Patients with rheumatoid arthritis (RA) have an elevated risk of interstitial lung disease (ILD), but methotrexate does not accentuate that risk and may in fact be protective, new data show. These were among key findings of a pair of studies reported at the annual European Congress of Rheumatology, held online this year due to COVID-19.

Although a guideline-recommended cornerstone in the management of RA, methotrexate has been associated with both hypersensitivity pneumonitis and diffuse lung disease. However, its involvement in the development of ILD among patients with RA is unclear.

A Danish study of more than 30,000 RA patients reported at the congress found that their risk of ILD was about three to five times that of the general population. However, risk did not differ significantly whether they had filled a methotrexate prescription or not.

In addition, a multinational case-control study of more than 1,000 RA patients also reported at the congress found that, compared with never-users of methotrexate, ever-users actually had a 59% lower likelihood of developing ILD.

However, both studies were limited by their retrospective design, Elizabeth R. Volkmann, MD, codirector of the connective tissue disease–related interstitial lung disease program at the University of California, Los Angeles, cautioned in an interview. Hence, there was likely systematic bias and confounding.

“I would interpret the conclusions of both studies with caution,” she maintained. “To understand how a particular intervention, such as methotrexate use, affects the outcome of ILD development, a prospective design is needed, which adequately adjusts for known ILD risk factors, such as male sex and smoking.”

As to whether the new findings are practice changing and how they might affect patient counseling, “the answers to these questions are not straightforward and depend on other patient-related factors,” according to Dr. Volkmann.
 

Danish nationwide study

René Cordtz, MD, a clinical assistant at the Center for Rheumatology and Spine Diseases, Rigshospitalet‐Gentofte, Copenhagen, and colleagues conducted a nationwide population-based cohort study using registry data from 1997 to 2015 to assess lung disease among patients with RA by prescriptions filled.

Results based on 30,512 RA patients showed that, compared with peers filling no methotrexate prescriptions, patients filling at least one did not have a significantly elevated risk of ILD at either 1 year of follow-up (hazard ratio, 1.03) or 5 years of follow-up (HR, 1.00). (Findings were similar for sulfasalazine, with respective nonsignificant HRs of 0.88 and 1.14.)

In addition, patients with RA had a similarly sharply elevated 5-year risk of ILD relative to the general population regardless of whether they had filled neither methotrexate nor sulfasalazine prescriptions (standardized incidence ratio, 3.38) or had filled prescriptions for methotrexate only (SIR, 3.63), sulfasalazine only (SIR, 4.12), or both (SIR, 5.45).

“RA patients have an increased risk of ILD, compared to the general population, which was not surprising, but very importantly, that risk was not further exacerbated in those treated with methotrexate,” Dr. Cordtz concluded. “We do acknowledge that purchasing your medicine is different from taking your medicine, which is why we found it extra reassuring that when requiring at least two methotrexate prescriptions to be considered exposed, it did not change our results.”

Multinational study

Pierre-Antoine Juge, MD, a rheumatologist at Bichat-Claude Bernard Hospital, Paris, and colleagues performed a case-control study among 482 RA patients with ILD and 741 RA patients without ILD in three cohorts: a French discovery cohort, a multinational (Brazilian, Italian, Mexican, United Kingdom, and United States) replication cohort, and a combined cohort. Those with methotrexate hypersensitivity pneumonitis were excluded.

Results showed that relative to peers without ILD, patients with ILD had a lower prevalence of ever having used methotrexate and had received a lower cumulative methotrexate dose, findings that were consistent across all three cohorts.

Methotrexate ever-use was associated with a significantly lower adjusted likelihood of ILD in the discovery cohort (odds ratio, 0.46), the replication cohort (OR, 0.38), and the combined cohort (OR, 0.41). Furthermore, ever-users were less commonly represented among patients with ILD regardless of chest high-resolution CT pattern (usual interstitial pneumonia pattern vs. not).

Finally, methotrexate use appeared to delay the adjusted time to onset of ILD by 3.5 years in the discovery cohort (P = .001), by 3.2 years in the replication cohort (P < .0001), and by 3.5 years in the combined cohort (P < .0001).

“Outside of methotrexate hypersensitivity pneumonitis, methotrexate was not a risk factor for RA-associated ILD in our study. We observed an inverse relationship that was similar whatever the high-resolution CT pattern,” Dr. Juge commented. “But this possible protective effect should be confirmed through a dedicated prospective, randomized, controlled trial.”

“Methotrexate should not be considered as a causal factor for RA-associated ILD, and its [discontinuation] should be discussed through a multidisciplinary discussion,” he recommended. In addition, “this study does not investigate the impact of methotrexate use on RA-associated ILD prognosis.”

The Danish study did not receive any specific funding, and none of its authors reported having any financial disclosures. The multinational study did not receive any specific funding. Dr. Juge disclosed that he had no relevant conflicts of interest, but many of his coauthors reported financial relationships with industry. Dr. Volkmann disclosed consulting for Boehringer Ingelheim and Forbius, and receiving grant support from Forbius and Corbus.

The MET inhibitor tepotinib produced responses in about half of advanced non–small cell lung cancer (NSCLC) patients with confirmed MET exon 14–skipping mutations in an open-label, phase 2 study.

The objective response rate was 46.5% among the 99 patients followed for 9 or more months, as assessed by independent reviewers. There were no complete responders, according to the reviewers.

However, the response rate according to investigator assessment was 55.6%, including two responses that were judged to be complete.

The median duration of response was 11.1 months according to reviewers and 14 months according to investigators.

“The success of this trial, alongside other studies on the same class of drugs, establishes MET exon 14 as an actionable target for non–small cell lung cancer,” said senior author Xiuning Le, MD, PhD, assistant professor in the department of thoracic/head and neck medical oncology at the University of Texas MD Anderson Cancer Center, Houston.

Dr. Le presented results from this trial as part of the American Society of Clinical Oncology virtual scientific program. Results were published simultaneously in the New England Journal of Medicine.

The trial, dubbed VISION, already won tepotinib approval in Japan to treat NSCLC patients with MET exon 14–skipping mutations. The Food and Drug Administration has granted tepotinib breakthrough status, and Merck, the drug’s manufacturer, plans to submit tepotinib for review this year.

The VISION trial enrolled 152 patients with NSCLC – 99 with at least 9 months of follow-up and 53 with shorter follow-up. The patients’ MET exon 14 mutations were confirmed by liquid or tissue biopsy.

The patients’ median age at baseline was 74 years, 54% were men, and almost half had no smoking history. Patients received tepotinib at 500 mg daily until disease progression or intolerable toxicity.

Overall, the VISION results “compare favorably” with those from studies of other MET inhibitors, the investigators wrote.

The 46.5% objective response rate (per independent reviewers) included the 99 patients with follow-up of at least 9 months who were liquid- or tissue-biopsy positive (combined group). The response rate was 48.5% among the 66 patients with positive liquid biopsies and 50% among the 60 patients with positive tissue biopsies.

The median progression-free survival was 8.5 months in the combined group, 8.5 months in the liquid-biopsy group, and 11 months in the tissue-biopsy group. The median overall survival was 17.1 months, 15.8 months, and 22.3 months, respectively.

The 11 patients with brain metastases at baseline had results that were in line with the other patients’ results. Patients with brain metastases had an objective response rate of 54.5%, a median response duration of 9.5 months, and a median progression-free survival of 10.9 months.

Overall, 88.8% of patients reported adverse events related to treatment, including peripheral edema in 63.2%, nausea in 25.7%, and diarrhea in 21.7%.

Grade 3-4 adverse events occurred in 27% of patients. Peripheral edema was the most common of these events, reported in 7.2% of patients.

“Proactive monitoring for peripheral edema is recommended and can be managed with temporary discontinuation of tepotinib or dose reduction,” the investigators wrote.

The death of a 79-year-old patient with respiratory failure and dyspnea, secondary to interstitial lung disease, was the only death considered to be treatment related.

The study was funded by Merck. Dr. Le and other investigators disclosed relationships, including employment, with the company.

Being aged older than 65 years was associated with the highest risk of people with rheumatic and musculoskeletal diseases (RMDs) needing hospital treatment for COVID-19, according to the first results to be reported from ReCoVery, the German national COVID-19 registry.

Older patients with RMDs were five times more likely than younger patients to be hospitalized if they tested positive for SARS‑CoV‑2 and developed COVID-19 (odds ratio, 5.1; 95% confidence interval, 2.3-11.4).

The likelihood of hospitalization was also significantly increased by the current or prior use of glucocorticoids (OR, 2.59; 95% CI, 1.2-5.4) and by the presence of cardiovascular disease (OR, 2.27; 95% CI, 1.2-5.4).

“The register is a joint initiative of the German Society for Rheumatology and the Justus Liebig University in Giessen,” explained Anne Regierer, MD, during a live session of the annual European Congress of Rheumatology, held online this year due to COVID-19.

“The current pandemic has changed all of our lives. For patients it brought a lot of uncertainty and fears,” said Dr. Regierer, of the German Rheumatism Research Center Berlin.

“The risk of SARS-CoV-2 infection in patients with inflammatory rheumatic diseases [IRD] is still largely unknown. We still don’t know whether they have a high risk of getting the infection or whether they have a higher risk of a severer case ... therefore there’s an urgent need to have data to generate evidence for the management of our patients.”

Launched at the end of March 2020, the German registry now includes data on 251 patients – 194 of whom have recovered – provided by more than 200 registered rheumatologists. The registry data have now been integrated into the EULAR COVID-19 Database, which is itself part of a global effort to better understand and optimally manage RMD patients during the pandemic.

“The data presented by Dr. Regierer looked at similar outcomes and found quite similar results, which is reassuring,” Kimme Hyrich, MD, PhD, professor of epidemiology at the University of Manchester (England) and a consultant rheumatologist in the Kellgren Centre for Rheumatology at Manchester University Hospitals NHS Foundation Trust, said in an interview.

“We are very grateful for this collaboration [with the German society and others]. Our first publication has looked at hospitalization, but with more data we may have the opportunity to look at less-common outcomes [e.g. death, other COVID complications] or within individual diseases or treatments. So far I don’t think we will come to a different conclusion,” observed Dr. Hyrich, who is on the steering committee for the EULAR COVID-19 Database.

“These initial data are reassuring in that the majority of cases of COVID reported to our database have recovered, including those who were hospitalized,” she said.

Current EULAR advice is to continue treatment with glucocorticoids in patients who are being chronically treated, but to use them at the lowest possible dose.

The objectives of this first analysis of the German registry was to provide a description of the patients who did and did not require hospitalization and those who needed ventilation, as well as look at possible risk factors for hospitalization.

Dr. Regierer reported that, of 192 patients they included – all with a positive lab test for SARS-CoV-2 – 128 (67%) did not require hospital admission. Of those that did (n = 64), 43 (22%) did not need ventilation and 21 (11%) did. Fifteen patients died, all of whom had been hospitalized, and all but one of them had needed ventilation.

Concerning the characteristics of the patients, those who needed hospital treatment with and without ventilation were older than those who were not admitted (70 vs. 65 vs. 54 years, respectively).

“Looking at the sexes, the gender distribution is also interesting. We see 69% females in the nonhospitalized patients, 65% of the inpatients without ventilation, but only 43% females in the ventilated patients. So in this group, the male patients are the majority,” Dr. Regierer observed.

Just over half of all patients in the nonhospitalized and the hospitalized without ventilation groups had IRD in remission, but those in the hospitalized with ventilation group less than one-fifth had their IRD under control.

“Of course we have to keep in mind the small sample sizes,” Dr. Regierer said, but the distribution of patients by disease type was “what you’d expect in clinical care.” The majority of patients in each of the three groups had RA (47%, 56%, and 57%), followed by psoriatic arthritis (19%, 7%, and 14%), axial spondyloarthritis (11%, 5%, and 0%), systemic lupus erythematosus (6%, 2%, and 0%), and vasculitis (1%, 5%, and 5%).

Patients who were hospitalized with and without ventilation were more likely to have more than one comorbidity than those who were not hospitalized with COVID-19.

“The most frequent comorbidity was cardiovascular disease with 58% and 76% in the inpatient groups,” Dr. Regierer reported. One-third of the nonhospitalized patients had a cardiovascular comorbidity.

“If we look at pulmonary disease, we see that 38% of the ventilator patients had an underlying pulmonary disease,” she added. This was in comparison with 19% of the hospitalized without ventilation and 13% of the nonhospitalized patients. Diabetes was another common comorbidity in hospitalized patients with (16%) and without (19%) ventilation versus just 2% of nonhospitalized patients. While these and other comorbidities such as chronic renal insufficiency were associated with higher odds ratios in the multivariate risk factor analysis, they did not reach statistical significance.

With regard to RMD treatments, more than 60% of patients in the hospitalized group had received treatment with glucocorticoids versus 37% of those who did not get admitted. No differences were seen for the other treatments.

Interestingly, “female sex, remission, and use of NSAIDs have an odds ratio smaller than 1. So there might be a lower risk of hospitalization associated with these factors,” Dr. Regierer said.

Dr. Regierer has received grant support and is part of speaker’s bureaus for a variety of pharmaceutical companies. Dr. Hyrich disclosed grant income from Bristol-Myers Squibb, UCB, and Pfizer, and receiving speaker fees from AbbVie.

Being aged older than 65 years was associated with the highest risk of people with rheumatic and musculoskeletal diseases (RMDs) needing hospital treatment for COVID-19, according to the first results to be reported from ReCoVery, the German national COVID-19 registry.

Older patients with RMDs were five times more likely than younger patients to be hospitalized if they tested positive for SARS‑CoV‑2 and developed COVID-19 (odds ratio, 5.1; 95% confidence interval, 2.3-11.4).

The likelihood of hospitalization was also significantly increased by the current or prior use of glucocorticoids (OR, 2.59; 95% CI, 1.2-5.4) and by the presence of cardiovascular disease (OR, 2.27; 95% CI, 1.2-5.4).

“The register is a joint initiative of the German Society for Rheumatology and the Justus Liebig University in Giessen,” explained Anne Regierer, MD, during a live session of the annual European Congress of Rheumatology, held online this year due to COVID-19.

“The current pandemic has changed all of our lives. For patients it brought a lot of uncertainty and fears,” said Dr. Regierer, of the German Rheumatism Research Center Berlin.

“The risk of SARS-CoV-2 infection in patients with inflammatory rheumatic diseases [IRD] is still largely unknown. We still don’t know whether they have a high risk of getting the infection or whether they have a higher risk of a severer case ... therefore there’s an urgent need to have data to generate evidence for the management of our patients.”

Launched at the end of March 2020, the German registry now includes data on 251 patients – 194 of whom have recovered – provided by more than 200 registered rheumatologists. The registry data have now been integrated into the EULAR COVID-19 Database, which is itself part of a global effort to better understand and optimally manage RMD patients during the pandemic.

“The data presented by Dr. Regierer looked at similar outcomes and found quite similar results, which is reassuring,” Kimme Hyrich, MD, PhD, professor of epidemiology at the University of Manchester (England) and a consultant rheumatologist in the Kellgren Centre for Rheumatology at Manchester University Hospitals NHS Foundation Trust, said in an interview.

“We are very grateful for this collaboration [with the German society and others]. Our first publication has looked at hospitalization, but with more data we may have the opportunity to look at less-common outcomes [e.g. death, other COVID complications] or within individual diseases or treatments. So far I don’t think we will come to a different conclusion,” observed Dr. Hyrich, who is on the steering committee for the EULAR COVID-19 Database.

“These initial data are reassuring in that the majority of cases of COVID reported to our database have recovered, including those who were hospitalized,” she said.

Current EULAR advice is to continue treatment with glucocorticoids in patients who are being chronically treated, but to use them at the lowest possible dose.

The objectives of this first analysis of the German registry was to provide a description of the patients who did and did not require hospitalization and those who needed ventilation, as well as look at possible risk factors for hospitalization.

Dr. Regierer reported that, of 192 patients they included – all with a positive lab test for SARS-CoV-2 – 128 (67%) did not require hospital admission. Of those that did (n = 64), 43 (22%) did not need ventilation and 21 (11%) did. Fifteen patients died, all of whom had been hospitalized, and all but one of them had needed ventilation.

Concerning the characteristics of the patients, those who needed hospital treatment with and without ventilation were older than those who were not admitted (70 vs. 65 vs. 54 years, respectively).

“Looking at the sexes, the gender distribution is also interesting. We see 69% females in the nonhospitalized patients, 65% of the inpatients without ventilation, but only 43% females in the ventilated patients. So in this group, the male patients are the majority,” Dr. Regierer observed.

Just over half of all patients in the nonhospitalized and the hospitalized without ventilation groups had IRD in remission, but those in the hospitalized with ventilation group less than one-fifth had their IRD under control.

“Of course we have to keep in mind the small sample sizes,” Dr. Regierer said, but the distribution of patients by disease type was “what you’d expect in clinical care.” The majority of patients in each of the three groups had RA (47%, 56%, and 57%), followed by psoriatic arthritis (19%, 7%, and 14%), axial spondyloarthritis (11%, 5%, and 0%), systemic lupus erythematosus (6%, 2%, and 0%), and vasculitis (1%, 5%, and 5%).

Patients who were hospitalized with and without ventilation were more likely to have more than one comorbidity than those who were not hospitalized with COVID-19.

“The most frequent comorbidity was cardiovascular disease with 58% and 76% in the inpatient groups,” Dr. Regierer reported. One-third of the nonhospitalized patients had a cardiovascular comorbidity.

Approximately one-fifth of patients undergoing hematopoietic stem cell transplantation (HSCT) develop posttraumatic stress disorder (PTSD), based on a retrospective analysis.

Patient factors at time of transplantation, such as low quality of life and high anxiety, predicted PTSD 6 months later, reported lead author Sarah Griffith, MD, of Massachusetts General Hospital, Boston, who presented findings as part of the American Society of Clinical Oncology virtual scientific program.

“We know that patients admitted for HSCT are often isolated in the hospital for a prolonged period of time, usually about 3-4 weeks, and that they endure substantial toxicities that impact both their physical and psychological well-being,” Dr. Griffith said. “We also know from the literature that HSCT can be considered a traumatic event and that it may lead to clinically significant PTSD symptoms.” But studies evaluating the prevalence and characteristics of PTSD in this patient population have been lacking, she noted.

Dr. Griffith and her colleagues therefore conducted a retrospective analysis involving 250 adults with hematologic malignancies who underwent autologous or allogeneic HSCT during clinical trials conducted from 2014 to 2016. Median patient age was 56 years.

The first objective of the study was to measure the prevalence of PTSD. The second was to characterize features of PTSD such as intrusion, which entails reliving experiences in the form of nightmares or flashbacks, and hypervigilance, which encompasses insomnia, irritability, and hyperarousal for threat. The third objective was to determine risk factors at baseline.

At time of admission for HSCT, after 2 weeks of hospitalization, and again 6 months after transplantation, patients were evaluated using the Functional Assessment of Cancer Therapy–Bone Marrow Transplant (FACT-BMT), and the Hospital Anxiety and Depression Scale (HADS), which measured of quality of life, anxiety, and depression. Six months after HSCT, patients also underwent screening for PTSD with the Post-Traumatic Stress Checklist (PTSD-CL). Multivariate regression models were used to determine predictive risk factors.

Six months after HSCT, 18.9% of patients had clinically significant PTSD symptoms; most common were symptoms of avoidance (92.3%), hypervigilance (92.3%), and intrusion (76.9%). Among those who did not have clinically significant PTSD, almost one-quarter (24.5%) demonstrated significant hypervigilance, while 13.7% showed symptoms of avoidance.

“Clinically significant PTSD symptoms are common in the transplant population,” Dr. Griffith said.

Baseline predictors of PTSD included single status and lower quality of life. More severe PTSD was predicted by single status, younger age, higher baseline scores for anxiety or depression, and increased anxiety during hospitalization.

Concluding her presentation, Dr. Griffith said that the findings, while correlative and not causative, should prompt concern and intervention.

“It is very important to be aware of and to manage PTSD symptoms in these patients,” she said. “There are several baseline factors that can be identified prior to HSCT that may illuminate patients at risk for developing worse PTSD symptoms down the road, and these patients may benefit from tailored supportive care interventions.”

Specifically, Dr. Griffith recommended integrating palliative care into hospitalization, as this has been shown to reduce anxiety.

In a virtual presentation, invited discussant Nirali N. Shah, MD, of the National Cancer Institute, Bethesda, Md., highlighted the importance of the findings, while also noting that the impact of palliative care on risk of PTSD has yet to be demonstrated.

Dr. Shah suggested that future research may be improved through use of a formal diagnosis for PTSD, instead of a PTSD checklist, as was used in the present study.

“And certainly long-term follow-up would be important to evaluate the utility of this tool looking at symptoms beyond 6 months,” she said.

Dr. Shah went on to discuss the relevance of the findings for pediatric populations, as children may face unique risk factors and consequences related to PTSD.

“[PTSD in children] may be impacted by family dynamics and structure,” Dr. Shah said. “Children may also have significant neurocognitive implications as a result of their underlying disease or prior therapy. They may experience chronic pain as they go out into adulthood and long-term survivorship, and may also struggle with symptoms of anxiety and depression.”

According to Dr. Shah, one previous study involving more than 6,000 adult survivors of childhood cancer found that PTSD was relatively common, with prevalence rate of 9%, suggesting that interventional work is necessary.

“Applying the data in the study from Griffith et al. suggests that evaluation in the more proximal posttransplant period for children is needed to specifically evaluate PTSD and symptoms thereof, and to try to use this to identify an opportunity for intervention,” Dr. Shah said.

“Pediatric-specific assessments are essential to optimally capture disease and/or age-specific considerations,” she added.

The study was funded by the Lymphoma and Leukemia Society. The investigators disclosed additional relationships with Vector Oncology, Pfizer, AstraZeneca, and Gaido Health/BCG Digital Ventures.

Irritability in adults with major depressive disorder (MDD) and stimulant use disorder (SUD) is strongly linked to suicidality and should be assessed by clinicians.

Three clinical trials of adults with MDD and one trial of adults with SUD showed that the link between irritability and suicidality was stronger than the association between depression severity and suicidal behaviors.

“Irritability is an important construct that is not often studied in adults with major depressive disorder,” Manish K. Jha, MD, of Icahn School of Medicine at Mount Sinai, New York, said in an interview.

“If you look at current diagnostic convention, irritability is not considered a symptom of major depressive episodes in adults, but below age 18, it is considered one of the two main symptoms,” Dr. Jha said.

The findings were presented at the virtual American Society of Clinical Psychopharmacology 2020 annual Meeting.
 

Clinically useful

Irritability is assessed using age-related norms of behavior, Dr. Jha said.

“The best way to conceptualize it is that it is the propensity to get angry easily or more frequently as compared to peers in response to frustration. I have a 2½-year old, and if he throws a tantrum, that is perfectly age appropriate. But if I do the same thing, it would be extreme irritability. The pediatric literature uses the word ‘grouchiness,’ but it is a little bit difficult to define, in part because it hasn’t been studied extensively,” he said.

To better understand the potential association between irritability and suicidality, the investigators reviewed results of three trials involving adults with MDD. These trials were CO-MED (Combining Medications to Enhance Depression Outcomes), which included 665 patients; EMBARC (Establishing Moderators and Biosignatures of Antidepressant Response in Clinical Care), which included 296 patients; and SAMS (Suicide Assessment Methodology Study), which included 266 patients.

They also examined the STRIDE (Stimulant Reduction Intervention Using Dosed Exercise) study, which was conducted in 302 adults with SUD.

All studies assessed irritability using the Concise Associated Symptom Tracking scale, a 5-point Likert scale. The trials also assessed suicidality with the Concise Health Risk Tracking Suicidal Thoughts.

The investigators found that irritability and suicidality were positively correlated. The association between irritability and suicidality was 2-11 times stronger than the link to overall depression.

Higher irritability at baseline predicted higher levels of suicidality at week 9 in CO-MED (P = .011), EMBARC (P < .0001), and STRIDE (P = .007), but not in SAMS (P = .21).

Greater reduction in irritability from baseline to week 4 predicted lower levels of suicidality at week 8 in CO-MED (P = .007), EMBARC (P < .0001), and STRIDE (P < .0001), but not in SAMS (P = .065).

Similarly, lower baseline levels and greater reductions in irritability were associated with lower levels of suicidality at week 28 of CO-MED, week 16 of EMBARC, and week 36 of STRIDE.

Dr. Jha speculated that by treating irritability, it may be possible to lower rates of subsequent suicidal ideation, and he believes that measuring irritability in MDD “has clinical utility.”
 

A common and disabling symptom

Commenting on the study, Sanjay J. Mathew, MD, professor of psychiatry and behavioral sciences at Baylor College of Medicine, Houston, said the findings provide further support that irritability is a relatively common and disabling symptom associated with major depression.

“The presence of significant irritability was associated with higher levels of suicidal ideation and is therefore highly relevant for clinicians to assess,” said Dr. Mathew, who was not part of the study.

“Early improvements in irritability are associated with better longer-term outcomes with antidepressant treatments, and this highlights the need for careful clinical evaluation early on in the course of antidepressant therapy, ideally within the first 2 weeks,” he said.

Greater reduction in irritability from baseline to week 4 predicted lower levels of suicidality at week 8 in CO-MED (P = .007), EMBARC (P < .0001), and STRIDE (P < .0001), but not in SAMS (P = .065).

Similarly, lower baseline levels and greater reductions in irritability were associated with lower levels of suicidality at week 28 of CO-MED, week 16 of EMBARC, and week 36 of STRIDE.

Dr. Jha speculated that by treating irritability, it may be possible to lower rates of subsequent suicidal ideation, and he believes that measuring irritability in MDD “has clinical utility.”
 

A common and disabling symptom

Commenting on the study, Sanjay J. Mathew, MD, professor of psychiatry and behavioral sciences at Baylor College of Medicine, Houston, said the findings provide further support that irritability is a relatively common and disabling symptom associated with major depression.

“The presence of significant irritability was associated with higher levels of suicidal ideation and is therefore highly relevant for clinicians to assess,” said Dr. Mathew, who was not part of the study.

“Early improvements in irritability are associated with better longer-term outcomes with antidepressant treatments, and this highlights the need for careful clinical evaluation early on in the course of antidepressant therapy, ideally within the first 2 weeks,” he said.

Irritability in adults with major depressive disorder (MDD) and stimulant use disorder (SUD) is strongly linked to suicidality and should be assessed by clinicians.

Three clinical trials of adults with MDD and one trial of adults with SUD showed that the link between irritability and suicidality was stronger than the association between depression severity and suicidal behaviors.

“Irritability is an important construct that is not often studied in adults with major depressive disorder,” Manish K. Jha, MD, of Icahn School of Medicine at Mount Sinai, New York, said in an interview.

“If you look at current diagnostic convention, irritability is not considered a symptom of major depressive episodes in adults, but below age 18, it is considered one of the two main symptoms,” Dr. Jha said.

The findings were presented at the virtual American Society of Clinical Psychopharmacology 2020 annual Meeting.
 

Clinically useful

Irritability is assessed using age-related norms of behavior, Dr. Jha said.

“The best way to conceptualize it is that it is the propensity to get angry easily or more frequently as compared to peers in response to frustration. I have a 2½-year old, and if he throws a tantrum, that is perfectly age appropriate. But if I do the same thing, it would be extreme irritability. The pediatric literature uses the word ‘grouchiness,’ but it is a little bit difficult to define, in part because it hasn’t been studied extensively,” he said.

To better understand the potential association between irritability and suicidality, the investigators reviewed results of three trials involving adults with MDD. These trials were CO-MED (Combining Medications to Enhance Depression Outcomes), which included 665 patients; EMBARC (Establishing Moderators and Biosignatures of Antidepressant Response in Clinical Care), which included 296 patients; and SAMS (Suicide Assessment Methodology Study), which included 266 patients.

They also examined the STRIDE (Stimulant Reduction Intervention Using Dosed Exercise) study, which was conducted in 302 adults with SUD.

All studies assessed irritability using the Concise Associated Symptom Tracking scale, a 5-point Likert scale. The trials also assessed suicidality with the Concise Health Risk Tracking Suicidal Thoughts.

The investigators found that irritability and suicidality were positively correlated. The association between irritability and suicidality was 2-11 times stronger than the link to overall depression.

Higher irritability at baseline predicted higher levels of suicidality at week 9 in CO-MED (P = .011), EMBARC (P < .0001), and STRIDE (P = .007), but not in SAMS (P = .21).

Greater reduction in irritability from baseline to week 4 predicted lower levels of suicidality at week 8 in CO-MED (P = .007), EMBARC (P < .0001), and STRIDE (P < .0001), but not in SAMS (P = .065).

Continuing adjuvant imatinib (Gleevec, Novartis) for 3 years rather than stopping at 1 year in patients with high-risk gastrointestinal stromal tumors (GIST) could halve the death rate over 10 years, phase 3 trial data suggest.

The most recent analysis of the SSGXVIII/AIO trial shows that, in about 400 patients who underwent surgery and had a high estimated risk of recurrence, there was a 50% increase in overall survival with longer treatment at 10 years on an efficacy analysis.

Moreover, there was a 30% improvement in recurrence-free survival (RFS) with 3 years vs 1 year of imatinib, with an even greater benefit seen in patients with a common tumor mutation.

The research was presented at the 2020 annual meeting of the American Society of Clinical Oncology (abstract 11503), held virtually because of the coronavirus pandemic.

Lead author Peter Reichardt, MD, Helios Klinikum Berlin-Buch, Berlin, Germany, said the results show that “3 years of adjuvant imatinib is highly superior” in terms of RFS and overall survival to 1 year of treatment.

“Overall, approximately 50% of deaths can be avoided during the first 10 years of follow-up after surgery with the longer adjuvant imatinib treatment.”

Study discussant Giovanni Grignani, MD, Division of Medical Oncology, Candiolo Cancer Institute, FPO-IRCCS, Turin, Italy, said that the “burning question” in the sarcoma space is: “Can we improve overall survival by reducing the risk of relapse with a perioperative treatment?

“We would like to able to identify patients for whom the cost of toxicity is paid off by an improvement in their outcome,” he added, noting that this is not achievable “and this is why perioperative treatment is so controversial in oncology.”

Grignani said the picture is a little different for GIST, as the relapse risk is unevenly distributed, the activity of imatinib is “extraordinary,” and the drug toxicity is “certainly bearable but not negligible.”

RFS is, however, affected by the inability of imatinib to eradicate resistant clones left behind by surgery, and replication resumes once the drug is stopped.

The current study nevertheless shows that overall survival “clearly favors 3-year imatinib therapy…with an impressive median follow-up of 119 months [10 years],” commented Patrick Leavey, MD, University of Texas Southwestern Medical Center, Dallas, in a highlights session.

He added that, in GIST, what might be considered “new progress” with the findings “is clarity over the length of imatinib therapy, which ... seems to be safe.”

Reichardt began by noting that several large randomized trials over the past decade have shown that adjuvant imatinib improves both RFS and overall survival.

However, “it is unknown whether imatinib improves overall survival after extended follow-up,” in addition to which “little is known about the long-term safety” of the drug in this setting.

To offer further insights, the protocol of SSGXVIII/AIO was amended in April 2017 to allow for a third analysis to be carried out once the last patient who entered the trial has been followed up for 10 years.
 

More Details

Reichardt recalled that the study, which was an open-label, multicenter phase 3 trial, involved GIST patients who were randomly assigned following surgery in a 1:1 fashion to imatinib for either 12 months or 36 months.

The patients were required to have a high-risk of recurrence, defined as at least one of the following:

• Tumor size >10 cm
• Tumor mitosis count >10/50 on high-powered microscopy (HPF)
• Tumor size >5 cm and mitosis count >5/50 HPF
• Tumor rupture, either spontaneously or at surgery.

Four hundred patients were recruited between February 2004 and September 2008, and 181 patients who were randomly assigned to 12 months of imatinib and 177 to 36 months were included in the efficacy analysis.

The median age of the patients was approximately 61 years, and half were female. The treatment groups were well-balanced in terms of their baseline characteristics.

Of note, 69% of patients in the 1-year treatment group and 71% of those given imatinib for 3 years had a detectable mutation in the KIT exon 11 site. The mean mitosis count was 10/50 and 8/50, respectively.

Over a median follow-up of 119 months (9 years, 11 months), 53% of 1-year treatment patients experienced a recurrence event, and 30% died, of whom 82% died with metastatic GIST.

In the 3-year treatment group, 44% experienced a recurrence event, and 18% died, with 83% of deaths from metastatic GIST.

On intention-to-treat analysis, RFS at 10 years was significantly higher with 3 years of imatinib than with 1 year, at 53% vs 42% (hazard ratio [HR], 0.66; P = .003).

Overall survival at 10 years was also higher with longer imatinib treatment, at 79% with 3 years of therapy vs 65% with 1 year (HR, 0.55; P = .004).

The team found on subgroup analysis that RFS was significantly better with 3-year than 1-year imatinib in patients with:

• A local mitotic count >10 (HR = 0.42)
• A central mitotic count >10 (HR = 0.50)
• A KIT exon 11 tumor mutation (HR = 0.57).

On the efficacy analysis, which included patients who signed informed consent, had GIST at pathology review, and no overt metastases at study entry, the HR for RFS with 3-year vs 1-year therapy was 0.70, whereas the HR for overall survival was 0.50.

Patients treated with imatinib for 3 years had a higher rate of any new cancer during follow-up, at 17%, vs 12% for those treated with imatinib for 1 year. Prostate cancer was the most common form of the disease in both groups.

Cardiac events were, in contrast, evenly distributed between the two groups, with 5% of 3-year patients and 6% of 1-year patients experiencing an event.

The American Diabetes Association’s 80th Scientific Sessions will forge ahead virtually this year in the face of the COVID-19 pandemic, with nearly all of its originally scheduled content to be presented online.

The meeting will take place online June 12-16, the same days it was slated to occur in Chicago and at the same times. All presentations were recorded in advance, but participants will be able to ask real-time questions during some sessions. Registered attendees – who paid a reduced fee – will have access to the online content for 90 days afterward.

ADA announced the shift in plans on April 3, after Chicago’s McCormick Place convention center became unavailable due to the COVID-19 pandemic. While some major medical meetings had to be canceled entirely or trimmed down online, “This is one of the international meetings that has had more time to really get ready to plan such a virtual session,” association co-president Robert H. Eckel, MD, told Medscape Medical News.

This year’s program features fewer blockbuster randomized clinical trials than in years past.

But it does offer a huge amount of clinical research focused on both type 1 and type 2 diabetes, children with diabetes, gestational diabetes, and much more. Also included are deep dives into optimal clinical translation of findings from previous cardiovascular outcomes trials (CVOTs).

Noteworthy sessions include four new automated insulin delivery system trials on Friday, new diabetes-specific data from the DAPA-HF trial on Saturday, and a debate on Sunday about the future of metformin as first-line therapy for people with established heart disease or at high risk.

And on Tuesday morning, full results from the CVOT VERTIS-CV, with the sodium-glucose cotransporter 2 (SGLT2) inhibitor ertugliflozin (Steglatro, Merck), will be reported.

Also presented on Tuesday will be the first cardiovascular and cancer outcomes from the Diabetes Prevention Program Outcomes Study (DPPOS).

The online content will cover roughly 90% of what was originally scheduled, meeting planning committee chair Jose C. Florez, MD, PhD, told Medscape Medical News.

There is no session officially addressing COVID-19, he said, because the topics were already finalized by February, but “I’m sure it will be discussed in informal exchanges ... the data are just coming out,” he said.

Florez also called attention to two symposia addressing the other major topic dominating today’s news: racial disparities. One on Friday will address that topic with regard to maternal/fetal health, and another on Monday will cover disparities in diabetes care generally.

“Both because of COVID-19 and how it has affected people with diabetes, and within that, disadvantaged people, more aggressively, and in the current context of how racism is coming to the surface, these two sessions will become very, very pertinent,” he said.
 

Putting the Treatment Pieces Together in Type 2 Diabetes

The Evaluation of Ertugliflozin Efficacy and Safety Cardiovascular Outcomes Trial (VERTIS-CV) session will include the major cardiovascular, metabolic, renal, and safety outcomes for that drug, along with a meta-analysis of outcomes from trials of several different SGLT2 inhibitors.

All eyes will be on the VERTIS-CV presentation because ertugliflozin broke ranks with the other drugs in this class and failed to produce statistically significant drops in the relevant endpoints, as detailed in top-line data issued by the company in April.

And the provocatively titled session, “DAPA-HF Update: Have We Lost SGLT2 inhibitors to Cardiologists?!” will include a review of the trial’s main findings presented at the European Society of Cardiology meeting in September 2019, and published a few weeks later in the New England Journal of Medicine, along with new data on patient-centered and metabolic outcomes, and diabetes prevention. An independent commentator will presumably address the session title’s question.

Eckel, who has been working to establish a new cardiometabolic medicine subspecialty, commented: “I think we have not lost it, but I think SGLT2 inhibitors are a perfect example of why we need physicians trained in this overlap of diabetes medicine and cardiology.”

And, he said, we may be coming to the end of the CVOTs trial phenomenon.

“I think unless there’s a whole new class of drugs developed, we may be done with CVOTs for dipeptidyl peptidase-4 (DPP-4) inhibitors, SGLT2 inhibitors, and glucagon-like peptide 1 (GLP-1) receptor agonists. We’ve learned a lot, and I’m not sure we need more other than mechanistic studies ... I don’t think we really know yet how SGLT2 inhibitors or GLP-1 agonists work,” Eckel said.

Metformin, on the other hand, has not been subject to a CVOT because it has been available as a generic since long before the US Food and Drug Administration mandated the CVOTs for new drugs for type 2 diabetes in 2008.

Such a trial is unlikely to be conducted at this point, but the new DPPOS data might actually come close, Florez noted.

The DPPOS is the observational follow-up of the landmark randomized DPP trial, which found that intensive lifestyle intervention and metformin reduced progression from prediabetes to type 2 diabetes.

Numerous additional outcomes have been reported over the years, but this will be the first-ever reporting of DPPOS data on both hard cardiovascular events and cancer incidence in people who have been continuously taking metformin for more than 20 years.

“There’s a lot of interest in whether metformin has an effect on cardiovascular events and cancer ... I think that’s going to be a very interesting session,” Florez said, noting that “short of a randomized clinical trial, which it’s hard to imagine would come to be, this is really, really good.”

Also examining metformin will be a debate on Sunday, “Should Metformin Be Considered First-Line Therapy for Individuals with Type 2 Diabetes With Established Arteriosclerotic Cardiovascular Disease (ASCVD) or at High Risk for ASCVD?”

And on Saturday, a debate will address another old-guard diabetes drug class, asking: “Is There a Current Place for Sulfonylureas in the Treatment of Type 2 Diabetes?”

Overall, Florez said, meeting attendees will come away with “a more clear understanding of the placement of SGLT2 inhibitors and GLP-1 agonists in the type 2 diabetes treatment algorithm.”

“What are the settings in which these [newer] drugs ought to be used, compared to the old-timers like metformin and sulfonylureas? One thing is having the trials, but the other is figuring out how you interpret these in deciding what happens at the point of care.”

Two more future-looking type 2 diabetes symposia of potential interest to clinicians are “Unraveling the Heterogeneity in Type 2 Diabetes” on Sunday and “Perspectives on the Future of Precision Diabetes Medicine — A Joint ADA/EASD Symposium” on Monday.
 

Type 1 Diabetes, Technology, and Kids

A symposium on Friday will feature four new clinical trials of automated insulin delivery systems for people with type 1 diabetes, the “US Advanced Hybrid Closed-Loop (AHCL) Pivotal Safety Study, FLAIR — An NIDDK-Sponsored International, Multi-site Randomized Crossover Trial of AHCL vs 670G,” the New Zealand AHCL randomized crossover trial, and the Horizon Automated Glucose Control System pre-pivotal trial data.

“Closed-loop devices are getting a lot of traction ... These trials will continue to advance the notion that these devices will narrow the glycemic range, prevent hypoglycemia, and improve quality of life because people don’t have to pay as much attention mentally to the management of the diabetes,” Florez said.

He added that although these trials “have been in the works for a while and they’re not big surprises, they continue to build a body of evidence suggesting that these devices will be part of our armamentarium in the very near future.”

And on Saturday, a debate will address the somewhat controversial question of whether continuous glucose monitoring in type 2 diabetes is worth the cost.

There will also be plenty of pediatric diabetes material presented this year, too.

On Sunday, there will be new insights from the Restoring Insulin Secretion (RISE) study, which examines prediabetes and type 2 diabetes in youth, and on Monday, 20-year data from the SEARCH for Diabetes in Youth Study will be reported.

And on Monday, the most recent findings from The Environmental Determinants of Diabetes in the Young (TEDDY) study of environmental triggers of type 1 diabetes will be presented.
 

All-Virtual Meeting: Pros and Cons

The all-virtual meeting format will have pluses and minuses, Eckel predicts.

Advantages include the fact that attendees don’t have to physically run from room to room or make difficult decisions about conflicting sessions.

“The fact that this meeting will be taking place in reality in terms of the timing of sessions, one can transition from one room to another in a matter of seconds if you want to,” he noted.

However, he observed, “a lot of interesting things happen in the hallways at meetings. Colleagues from around the world get together and knock heads about their ongoing research and potential collaborations can be formulated.

“Opportunities to engage with one another beyond the formality of the meeting is going to be lost to some extent.”

What’s more, the sessions will all be in Central US (Chicago) time, “So if you live in Thailand, the session may be occurring at a time when you’re in bed. If you want to see it live, then you’ve got to get up. Then you can ask a question.”

On the other hand, since all the content will be available online for 90 days, “if you want to stay in bed and you live in Thailand, you can get up a week from now during the day and log into a session you may have missed.”

Indeed, Florez said, “One silver lining of this virtual conference is that we’ve lowered the barriers for people to attend. It’s much more global. We’ve had an amazing influx of new registrants who were not planning on coming and were not registered for the original meeting and have registered since [more than 10,000 at the time of writing], and they continue to pile in.”

“We plan to reach people we haven’t reached before. The big question for ADA moving forward will be how much this can become a permanent feature, where even if we do it in person in the future, maybe we offer at least some virtual options so that our reach can go farther.”

Eckel has reported sitting on the scientific advisory board for a Kowa Company trial of pemafibrate and on an advisory board for Novo Nordisk. Florez has reported being a speaker for Novo Nordisk and receiving an honorarium from ADA for chairing the conference planning committee.

The American Diabetes Association’s 80th Scientific Sessions will forge ahead virtually this year in the face of the COVID-19 pandemic, with nearly all of its originally scheduled content to be presented online.

The meeting will take place online June 12-16, the same days it was slated to occur in Chicago and at the same times. All presentations were recorded in advance, but participants will be able to ask real-time questions during some sessions. Registered attendees – who paid a reduced fee – will have access to the online content for 90 days afterward.

ADA announced the shift in plans on April 3, after Chicago’s McCormick Place convention center became unavailable due to the COVID-19 pandemic. While some major medical meetings had to be canceled entirely or trimmed down online, “This is one of the international meetings that has had more time to really get ready to plan such a virtual session,” association co-president Robert H. Eckel, MD, told Medscape Medical News.

This year’s program features fewer blockbuster randomized clinical trials than in years past.

But it does offer a huge amount of clinical research focused on both type 1 and type 2 diabetes, children with diabetes, gestational diabetes, and much more. Also included are deep dives into optimal clinical translation of findings from previous cardiovascular outcomes trials (CVOTs).

Noteworthy sessions include four new automated insulin delivery system trials on Friday, new diabetes-specific data from the DAPA-HF trial on Saturday, and a debate on Sunday about the future of metformin as first-line therapy for people with established heart disease or at high risk.

And on Tuesday morning, full results from the CVOT VERTIS-CV, with the sodium-glucose cotransporter 2 (SGLT2) inhibitor ertugliflozin (Steglatro, Merck), will be reported.

Also presented on Tuesday will be the first cardiovascular and cancer outcomes from the Diabetes Prevention Program Outcomes Study (DPPOS).

The online content will cover roughly 90% of what was originally scheduled, meeting planning committee chair Jose C. Florez, MD, PhD, told Medscape Medical News.

There is no session officially addressing COVID-19, he said, because the topics were already finalized by February, but “I’m sure it will be discussed in informal exchanges ... the data are just coming out,” he said.

Florez also called attention to two symposia addressing the other major topic dominating today’s news: racial disparities. One on Friday will address that topic with regard to maternal/fetal health, and another on Monday will cover disparities in diabetes care generally.

“Both because of COVID-19 and how it has affected people with diabetes, and within that, disadvantaged people, more aggressively, and in the current context of how racism is coming to the surface, these two sessions will become very, very pertinent,” he said.
 

Putting the Treatment Pieces Together in Type 2 Diabetes

The Evaluation of Ertugliflozin Efficacy and Safety Cardiovascular Outcomes Trial (VERTIS-CV) session will include the major cardiovascular, metabolic, renal, and safety outcomes for that drug, along with a meta-analysis of outcomes from trials of several different SGLT2 inhibitors.

All eyes will be on the VERTIS-CV presentation because ertugliflozin broke ranks with the other drugs in this class and failed to produce statistically significant drops in the relevant endpoints, as detailed in top-line data issued by the company in April.

And the provocatively titled session, “DAPA-HF Update: Have We Lost SGLT2 inhibitors to Cardiologists?!” will include a review of the trial’s main findings presented at the European Society of Cardiology meeting in September 2019, and published a few weeks later in the New England Journal of Medicine, along with new data on patient-centered and metabolic outcomes, and diabetes prevention. An independent commentator will presumably address the session title’s question.

Eckel, who has been working to establish a new cardiometabolic medicine subspecialty, commented: “I think we have not lost it, but I think SGLT2 inhibitors are a perfect example of why we need physicians trained in this overlap of diabetes medicine and cardiology.”

And, he said, we may be coming to the end of the CVOTs trial phenomenon.

“I think unless there’s a whole new class of drugs developed, we may be done with CVOTs for dipeptidyl peptidase-4 (DPP-4) inhibitors, SGLT2 inhibitors, and glucagon-like peptide 1 (GLP-1) receptor agonists. We’ve learned a lot, and I’m not sure we need more other than mechanistic studies ... I don’t think we really know yet how SGLT2 inhibitors or GLP-1 agonists work,” Eckel said.

Metformin, on the other hand, has not been subject to a CVOT because it has been available as a generic since long before the US Food and Drug Administration mandated the CVOTs for new drugs for type 2 diabetes in 2008.

Such a trial is unlikely to be conducted at this point, but the new DPPOS data might actually come close, Florez noted.

The DPPOS is the observational follow-up of the landmark randomized DPP trial, which found that intensive lifestyle intervention and metformin reduced progression from prediabetes to type 2 diabetes.

Numerous additional outcomes have been reported over the years, but this will be the first-ever reporting of DPPOS data on both hard cardiovascular events and cancer incidence in people who have been continuously taking metformin for more than 20 years.

“There’s a lot of interest in whether metformin has an effect on cardiovascular events and cancer ... I think that’s going to be a very interesting session,” Florez said, noting that “short of a randomized clinical trial, which it’s hard to imagine would come to be, this is really, really good.”

Also examining metformin will be a debate on Sunday, “Should Metformin Be Considered First-Line Therapy for Individuals with Type 2 Diabetes With Established Arteriosclerotic Cardiovascular Disease (ASCVD) or at High Risk for ASCVD?”

And on Saturday, a debate will address another old-guard diabetes drug class, asking: “Is There a Current Place for Sulfonylureas in the Treatment of Type 2 Diabetes?”

Overall, Florez said, meeting attendees will come away with “a more clear understanding of the placement of SGLT2 inhibitors and GLP-1 agonists in the type 2 diabetes treatment algorithm.”

“What are the settings in which these [newer] drugs ought to be used, compared to the old-timers like metformin and sulfonylureas? One thing is having the trials, but the other is figuring out how you interpret these in deciding what happens at the point of care.”

Two more future-looking type 2 diabetes symposia of potential interest to clinicians are “Unraveling the Heterogeneity in Type 2 Diabetes” on Sunday and “Perspectives on the Future of Precision Diabetes Medicine — A Joint ADA/EASD Symposium” on Monday.
 

Type 1 Diabetes, Technology, and Kids

A symposium on Friday will feature four new clinical trials of automated insulin delivery systems for people with type 1 diabetes, the “US Advanced Hybrid Closed-Loop (AHCL) Pivotal Safety Study, FLAIR — An NIDDK-Sponsored International, Multi-site Randomized Crossover Trial of AHCL vs 670G,” the New Zealand AHCL randomized crossover trial, and the Horizon Automated Glucose Control System pre-pivotal trial data.

“Closed-loop devices are getting a lot of traction ... These trials will continue to advance the notion that these devices will narrow the glycemic range, prevent hypoglycemia, and improve quality of life because people don’t have to pay as much attention mentally to the management of the diabetes,” Florez said.

He added that although these trials “have been in the works for a while and they’re not big surprises, they continue to build a body of evidence suggesting that these devices will be part of our armamentarium in the very near future.”

Adding aggressive local radiotherapy to treatment with tyrosine kinase inhibitor (TKI) significantly improved progression-free and overall survival in patients with previously untreated, EGFR-mutated, oligometastatic non–small cell lung cancer (NSCLC) in a phase 3 trial presented as part of the American Society of Clinical Oncology virtual scientific program.

Sixty-eight patients were randomized at diagnosis to receive a first-generation TKI plus stereotactic body radiation therapy (SBRT) to all disease sites. The other 68 patients were randomized to receive a TKI alone, but 3 patients were lost follow-up and not included in the analysis. The TKIs used were gefitinib, erlotinib, and icotinib.

At baseline, patients had a maximum of two lesions in any one organ and no more than five metastases overall. Patients with brain metastases were excluded.

The median progression-free survival was 20.2 months in the SBRT arm and 12.5 months in the TKI-only arm (hazard ratio, 0.618; P < .001). The median overall survival was 25.5 months and 17.4 months, respectively (HR, 0.682; P < .001).

There were no grade 4/5 adverse events nor any statistically significant between-group differences in grade 3 events.
 

‘Compelling’ data with caveats

The study results suggest that “aggressive local therapy to sites at diagnosis should be explored further in large cohort phase 3 trials as a standard treatment option in this clinical scenario,” said investigator Xiao-shan Wang, MD, PhD, of the University of Electronic Science and Technology of China and Sichuan Provincial People’s Hospital in Chengdu.

“The data are compelling,” Dr. Wang added. “As we attempt to maximize the benefits of EGFR-directed targeted therapies, we are likely going to be moving away from a sequentially administered approach to treatment and considering combinations.”

The new findings, combined with prior phase 2 results, support “incorporation of upfront SBRT with TKI into practice for selected patients with oligometastatic disease, with the open question remaining of how many metastases are too many,” said study discussant Rachel Sanborn, MD, of Providence Cancer Institute Franz Clinic in Portland, Ore.

However, “it’s important to make note of the baseline characteristics of the patients enrolled,” she said.

Twelve percent of patients in the control arm and 4% of those in the SBRT group had EGFR exon 20 insertions. This “imbalance could have negatively impacted the outcomes in the TKI-alone arm,” Dr. Sanborn said.

Also, a higher proportion of patients in the TKI-alone arm received gefitinib, and “there was no information offered on second-line therapies in the study, which might have also affected outcomes,” Dr. Sanborn added.
 

Additional details

The study (NCT02893332) enrolled NSCLC patients with a life expectancy of at least 6 months and an Eastern Cooperative Oncology Group performance status score of 0-2. NSCLC was confirmed by pathology and EGFR mutations by gene sequencing.

The radiation dose was 25-40 Gy in five fractions. Gefitinib was used in 47% of patients in the SBRT arm and 58% of the control group. Erlotinib was used in 44% of the SBRT arm and 35% of controls. Icotinib was used by less than 10% of patients in each group.

Grade 3 skin rash occurred in 50% of patients in the SBRT arm and 62% of those in the TKI-alone arm. Grade 3 pneumonitis occurred in 30% and 15%, respectively. Grade 3 esophagitis occurred in 15% of patients in both arms.

One patient in the TKI arm had severe liver injury. One patient in the SBRT arm fractured a rib, which was considered probably related to the radiation.

Multivariate analysis revealed that, in addition to SBRT, lower baseline performance status score (0 vs. 1-2) and fewer metastases (<2 vs. ≥3) were protective for progression-free survival. Lower performance scores, fewer metastases, lower T stage (T1-2 vs. T3-4), and exon 19 versus exon 20 and 21 mutations were protective for overall survival.

The study arms were well balanced at baseline. The mean patient age was 66.9 years in the SBRT arm and 63.32 years in the TKI-only arm. In both arms, most patients were women (63% and 60%, respectively).

The study was sponsored by Sichuan Provincial People’s Hospital. The investigators and Dr. Sanborn have no relevant disclosures.

The new findings, combined with prior phase 2 results, support “incorporation of upfront SBRT with TKI into practice for selected patients with oligometastatic disease, with the open question remaining of how many metastases are too many,” said study discussant Rachel Sanborn, MD, of Providence Cancer Institute Franz Clinic in Portland, Ore.

However, “it’s important to make note of the baseline characteristics of the patients enrolled,” she said.

Twelve percent of patients in the control arm and 4% of those in the SBRT group had EGFR exon 20 insertions. This “imbalance could have negatively impacted the outcomes in the TKI-alone arm,” Dr. Sanborn said.

Also, a higher proportion of patients in the TKI-alone arm received gefitinib, and “there was no information offered on second-line therapies in the study, which might have also affected outcomes,” Dr. Sanborn added.
 

Additional details

The study (NCT02893332) enrolled NSCLC patients with a life expectancy of at least 6 months and an Eastern Cooperative Oncology Group performance status score of 0-2. NSCLC was confirmed by pathology and EGFR mutations by gene sequencing.

The radiation dose was 25-40 Gy in five fractions. Gefitinib was used in 47% of patients in the SBRT arm and 58% of the control group. Erlotinib was used in 44% of the SBRT arm and 35% of controls. Icotinib was used by less than 10% of patients in each group.

Grade 3 skin rash occurred in 50% of patients in the SBRT arm and 62% of those in the TKI-alone arm. Grade 3 pneumonitis occurred in 30% and 15%, respectively. Grade 3 esophagitis occurred in 15% of patients in both arms.

One patient in the TKI arm had severe liver injury. One patient in the SBRT arm fractured a rib, which was considered probably related to the radiation.

Multivariate analysis revealed that, in addition to SBRT, lower baseline performance status score (0 vs. 1-2) and fewer metastases (<2 vs. ≥3) were protective for progression-free survival. Lower performance scores, fewer metastases, lower T stage (T1-2 vs. T3-4), and exon 19 versus exon 20 and 21 mutations were protective for overall survival.

The study arms were well balanced at baseline. The mean patient age was 66.9 years in the SBRT arm and 63.32 years in the TKI-only arm. In both arms, most patients were women (63% and 60%, respectively).

The study was sponsored by Sichuan Provincial People’s Hospital. The investigators and Dr. Sanborn have no relevant disclosures.

Despite the ever-increasing acceptance of medical cannabis and its notably common use in patients with multiple sclerosis (MS), clinicians treating those patients still may be poorly informed about risks, benefits, regulations, and proper uses, experts say.

“There is evidence of a ‘clinical void,’ with clinicians on one side and people with MS and other conditions on the other that doesn’t usually exist regarding therapies that people with MS are using,” said Allen C. Bowling, MD, PhD, director of the NeuroHealth Institute and clinical professor of neurology at the University of Colorado, in Aurora. His presentation was part of the virtual meeting of the Consortium of Multiple Sclerosis Centers (CMSC).

While approximately 8% of the general population uses cannabis, evidence shows that the proportion of people with MS who do so ranges from 9% to 38%, for an average of about 20%, Dr. Bowling noted. Yet, according to research, only about 20% of those actually discuss their cannabis use with their clinicians, which could have potentially adverse implications in the management of the disease.

As an example, Dr. Bowling described a case of his own involving a stroke syndrome associated with cannabis use – reversible cerebral vasoconstriction syndrome (RCVS), which he mistook for an MS flare-up. “I had a patient who developed RCVS, but because it appeared to be an MS attack, I was treating her with corticosteroids, and she kept getting worse,” he said. “It’s very important for MS clinicians to be aware of this stroke syndrome that can mimic an MS attack. The way to rule it out is with CT angiography.”
 

Misconceptions common among clinicians

Studies underscore that such misconceptions could be common. One recent study showed that as many as 90% of residents and fellows did not feel prepared to recommend or answer questions on cannabis use, and in fact, most states do not even require physicians to have training in medical uses of cannabis, Dr. Bowling noted.

Other research shows that the rates of clinicians with high knowledge in medical cannabis use are in the single digits, while many have no cannabis training at all.

In a survey of 556 physicians taken as recently as January 2020, 47% gave incorrect responses regarding tetrahydrocannabinol (THC), while 33% reported being familiar with “nano-cannabinoids” – which don’t even exist, and the term was created for the sake of the survey.

Clinicians’ misconceptions about the regulation of cannabis was especially eyebrow raising, Dr. Bowling indicated. “The part that concerns me the most is regarding dispensary cannabis products – 17% of respondents thought the products were Food and Drug Administration–controlled and 25% said they thought that dispensary products were FDA approved,” he said.

There are, meanwhile, no formal clinical studies evaluating the medical efficacy of any products sold in U.S. cannabis dispensaries, much less FDA regulation, Dr. Bowling said.

Among the most recent research of cannabis use among MS patients is a real-world study of more than 2,000 patients with MS in Denmark. Said to be the most comprehensive survey of cannabis use among MS patients to date, the researchers found that 21% of patients reported cannabis use in the past year, with only 21% of those having a prescription to use the drug legally because of strict regulations in Denmark.

Respondents reported that the primary reasons for use in MS were to alleviate pain (61%), spasticity (52%), and sleep disturbances (46%). The most common adverse effects were drowsiness (30%), feeling quiet/subdued (23%), and dizziness (13%), with effects that were mild to moderate.

And a 2019 study of electronic medical record data for 561 patients with multiple sclerosis in British Columbia, Canada, showed that 19% reported using cannabis, with 71% reporting use for alleviation of pain, 71% for sleep, 44% for mood, and 40% for spasticity.

Dr. Bowling said the findings are consistent with his clinical experience in treating patients in Colorado, where medical cannabis has been legal for about 2 decades. “It seems that people who benefit most are those who use small amounts and typically use it for alleviation of pain and/or spasticity that interferes with sleep,” he said.

However, with a lack of regulation about the true components in dispensary products, there are many uncertainties about what works or doesn’t. “Very anecdotally, preparations that are high in cannabidiol (CBD) and low in tetrahydrocannabinol (THC, the main psychoactive compound in cannabis) seem the most helpful. Pure CBD preparations (i.e., with no THC) seem less effective,” Dr. Bowling noted.

Other recent evidence on cannabis use in MS, however, suggests important benefits once patients abstain from its use.

However, the exceptionally wide array of components in unregulated cannabis accounts for substantial variety in potency, benefits, and side effects, Dr. Bowling said.

He pointed out one recent study looking mainly at patients with MS who regularly smoked cannabis and showed cognitive improvements upon abstaining. The study included 40 MS patients who reported smoking cannabis regularly – at least 4 days per week for multiple years – who were randomized to continue their cannabis use or withdraw.

While there were no cognitive differences among the patients at baseline, after 28 days, the abstinence group showed significant improvements on functional MRI in every cognitive index (P < .0001 for all). On the Symbol Digit Modalities Test at day 28, the withdrawal group completed more trials correctly (P < .012) and had a faster reaction time (P < .002) that was associated with significantly increased activation in brain regions known to be associated with performance of the test, including the bilateral inferior frontal gyri, caudate, and declive/cerebellum (P < .001 for all regions), the authors said.

“These results reveal that patients with multiple sclerosis who are frequent, long-term cannabis users can show significant improvements in memory, processing speed, and executive function after 28 days of drug abstinence,” the authors reported.
 

Addiction, distinguishing cannabis from MS symptoms

Dr. Bowling said that, while the findings are consistent with his own clinical observations, abstinence isn’t always easy. “I’ve seen patients with cognitive impairment whose cognition and overall day-to-day function have improved with discontinuation of cannabis,” he said. “For some of these patients, however, it was a long-term challenge to discontinue cannabis because they were addicted.”

Addiction to cannabis in MS in fact may be more common than many realize, and comes with a host of other adverse effects, Dr. Bowling said. “In my practice, I have definitely seen many cases of addiction. I think that it’s very underdiagnosed. In addition to cognitive dysfunction, it can worsen anxiety and depression and decrease balance, leading to falls.”

The RCVS risk is another concern, and changes in liver enzymes should also raise a red flag when MS patients are cannabis users, Bowling added.

“I’ve seen in multiple patients where the liver enzymes went up and I thought it was because of the disease-modifying therapy, but it turned out to have been because the patient had started CBD, so you need to be aware of potential hepatotoxicity.”

“The bottom line is that we don’t have strong data in this area and herbs are extremely complex with many unknown constituents.”

Dr. Bowling noted that pure CBD or CBD-enriched products would be expected to produce less cognitive dysfunction than does regular cannabis smoking, “however, it’s important to keep in mind that a ‘CBD-enriched’ product could have low but still significant THC content,” he said.

Dr. Bowling reported relationships with Bristol-Myers Squibb, EMD Serono, Genentech, Genzyme, Greenwich Biosciences, and Novartis, and he received royalties from Springer Publishing.

The variability in functional performance within and between levels of disability measured by the Expanded Disability Status Scale (EDSS) call into question the reliability of the EDSS itself, according to researchers.

Preferred walking speed, for example, may vary by as much as 20% among patients with the same EDSS score. “Even though it is considered a walking scale, your scale defined groups of homogeneous disability are not even homogeneous for quantified measurement of walking ability,” said Mark Gudesblatt, MD, medical director of the Comprehensive MS Care Center at South Shore Neurologic Associates in Patchogue, N.Y. “That’s a problem.”

Dr. Gudesblatt’s study was presented at the virtual meeting of the Consortium of Multiple Sclerosis Centers (CMSC).

John F. Kurtzke, MD, developed the EDSS in 1967. The scale has become a standard outcome of clinical trials, alongside MRI measures and annualized relapse rates. More than 15 therapies for MS have received regulatory approval in part based on their effects on EDSS outcomes. Furthermore, the recently proposed treatment goal of no evidence of disease activity includes the EDSS among its criteria.

Functional ability, however, which the EDSS measures, depends on various factors such as cognitive function, manual dexterity, and ambulation. If the degree of variability of these factors is greater than 20% within groups defined as having similar disability, this scale would no longer be valid, according to Dr. Gudesblatt.

To analyze the variability in functional performance in groups of patients with similar disability, Dr. Gudesblatt and colleagues retrospectively reviewed data from a prospective MS registry. Participants underwent multidimensional computerized cognitive testing and digital gait analysis. They also submitted patient-reported outcomes for hand function while undergoing simultaneous measurements of Patient-Determined Disease Steps (PDDS) or EDSS. For the analysis, Dr. Gudesblatt and colleagues defined groups of “adjacent” EDSS scores as follows: from 0 to 2.5, from 3 to 4.5, from 5 to 6.5, and greater than 7.

In all, 258 patients with MS underwent cognitive testing. Of this group, 73% of patients were women, and mean age was 46 years. The proportion of overlap in multidomain computerized cognitive testing global summary score of 7 domains among patients with adjacent EDSS scores was 65%. The researchers found 42% overlap among patients at the extremes of the EDSS scale. The proportion of overlap in accumulative cognitive impairment (i.e., the number of cognitive domains impaired by greater than one standard deviation) was 72% across adjacent EDSS groups and 38% across extreme EDSS groups.

Among 254 patients with MS who underwent evaluation of walking, 72% were women, and mean age was 46 years. The mean normalized velocity of preferred walking speed varied by more than 20% within EDSS groups and overlapped by more than 20% between groups.

A total of 783 patients underwent evaluation of hand function and tremor. About 74% of these participants were women, and mean age was 49 years. The variability across all PDDS groups (i.e., 0 to 1, 2 to 4, and greater than 4) was greater than 50%. Adjacent PDDS groups had overlap of more than 50%, and the extremes had an overlap of greater than 32%.

“The criteria for the diagnosis [of MS] have undergone multiple revisions, but the scale to define the disability remains unchanged,” said Dr. Gudesblatt. “It’s all about trying to do the right thing for the right patient at the right time for the right reason. We cannot go by our own perceptions. You need to have objective not subjective information to appropriately improve measurements of disease trajectory. The neurologist must move beyond the hammer and tuning fork, must move to objective, quantitative, examiner-independent, multidimensional measures of important aspects of disease to enhance identification of critical disease impact along a continuum so as to improved shared decision making with patient centric objective data to improve outcomes and reduce disability.”

Dr. Gudesblatt has served on speakers bureaus for Acorda, Amgen, Medtronic, and Saol Therapeutics. He has performed contracted research for Biogen, EMD Serono, Novartis, Sanofi, and Teva. The study was conducted without external funding.

John F. Kurtzke, MD, developed the EDSS in 1967. The scale has become a standard outcome of clinical trials, alongside MRI measures and annualized relapse rates. More than 15 therapies for MS have received regulatory approval in part based on their effects on EDSS outcomes. Furthermore, the recently proposed treatment goal of no evidence of disease activity includes the EDSS among its criteria.

Functional ability, however, which the EDSS measures, depends on various factors such as cognitive function, manual dexterity, and ambulation. If the degree of variability of these factors is greater than 20% within groups defined as having similar disability, this scale would no longer be valid, according to Dr. Gudesblatt.

To analyze the variability in functional performance in groups of patients with similar disability, Dr. Gudesblatt and colleagues retrospectively reviewed data from a prospective MS registry. Participants underwent multidimensional computerized cognitive testing and digital gait analysis. They also submitted patient-reported outcomes for hand function while undergoing simultaneous measurements of Patient-Determined Disease Steps (PDDS) or EDSS. For the analysis, Dr. Gudesblatt and colleagues defined groups of “adjacent” EDSS scores as follows: from 0 to 2.5, from 3 to 4.5, from 5 to 6.5, and greater than 7.

In all, 258 patients with MS underwent cognitive testing. Of this group, 73% of patients were women, and mean age was 46 years. The proportion of overlap in multidomain computerized cognitive testing global summary score of 7 domains among patients with adjacent EDSS scores was 65%. The researchers found 42% overlap among patients at the extremes of the EDSS scale. The proportion of overlap in accumulative cognitive impairment (i.e., the number of cognitive domains impaired by greater than one standard deviation) was 72% across adjacent EDSS groups and 38% across extreme EDSS groups.

Among 254 patients with MS who underwent evaluation of walking, 72% were women, and mean age was 46 years. The mean normalized velocity of preferred walking speed varied by more than 20% within EDSS groups and overlapped by more than 20% between groups.

A total of 783 patients underwent evaluation of hand function and tremor. About 74% of these participants were women, and mean age was 49 years. The variability across all PDDS groups (i.e., 0 to 1, 2 to 4, and greater than 4) was greater than 50%. Adjacent PDDS groups had overlap of more than 50%, and the extremes had an overlap of greater than 32%.

“The criteria for the diagnosis [of MS] have undergone multiple revisions, but the scale to define the disability remains unchanged,” said Dr. Gudesblatt. “It’s all about trying to do the right thing for the right patient at the right time for the right reason. We cannot go by our own perceptions. You need to have objective not subjective information to appropriately improve measurements of disease trajectory. The neurologist must move beyond the hammer and tuning fork, must move to objective, quantitative, examiner-independent, multidimensional measures of important aspects of disease to enhance identification of critical disease impact along a continuum so as to improved shared decision making with patient centric objective data to improve outcomes and reduce disability.”

Dr. Gudesblatt has served on speakers bureaus for Acorda, Amgen, Medtronic, and Saol Therapeutics. He has performed contracted research for Biogen, EMD Serono, Novartis, Sanofi, and Teva. The study was conducted without external funding.
