Conference Coverage

SAN ANTONIO – For patients with hormone receptor-positive/HER2-negative (HR+/HER2–) breast cancers resistant to aromatase inhibitors, the combination of the investigational AKT inhibitor capivasertib with the selective estrogen receptor degrader fulvestrant (Faslodex) was associated with significant improvement in progression-free survival compared with fulvestrant alone in the CAPItelllo-291 study recently presented at the San Antonio Breast Cancer Symposium.

The benefit of adding capivasertib to fulvestrant was also seen in patients with previous exposure to cyclin-dependent kinase 4/6 (CDK4/6) inhibitors and in patients with liver metastases, reported Nicholas Turner, MD, PhD, of the Institute of Cancer Research and Royal Marsden NHS Foundation Trust in London.

“Capivasertib plus fulvestrant has the potential to be a future treatment option for patients with hormone receptor–positive advanced breast cancer who have progressed on an endocrine-based regimen,” he said.
 

AKT alterations

Many HR+/HER2– advanced breast cancers have activation of the AKT pathway through alteration in PIK3CA, AKT1, and PTEN, but this activation can also occur in the absence of genetic alterations. AKT signaling is also a mechanism of resistance to endocrine therapy, Dr. Turner said.

Capivasertib, a select inhibitor of the AKT isoforms 1, 2, and 3, was combined with fulvestrant in the phase 2 FAKTION trial. The combination was associated with significant improvements in both progression-free survival (PFS) and overall survival (OS) compared with fulvestrant plus placebo in CDK4/6-naive postmenopausal women with aromatase inhibitor–resistant HR+/HER2– advanced breast cancer. The clinical benefit in this trial was more pronounced among patients with tumors bearing AKT pathway alterations, he said.

In the phase 3 CAPItello study, Dr. Turner and colleagues enrolled men and both pre- and postmenopausal women with HR+/HER2– advanced breast cancer who experienced recurrence either during therapy with adjuvant aromatase inhibitor or within 12 months of the end of therapy, or who had disease progression while on prior aromatase inhibitor therapy for advanced breast cancer.

The patients could have no more than two prior lines of endocrine therapy and no more than one prior line of chemotherapy for advanced breast cancer, and no prior selective estrogen receptor degrader (SERD), mTOR inhibitor, PI3K inhibitor, or AKT inhibitor. Patients with hemoglobin A1c below 8% and with diabetes not requiring insulin were eligible for the study. After stratification for liver metastases, prior CDK4/6 inhibitor therapy, and geographic region, 708 patients were randomized to either capivasertib 400 mg twice daily 4 days on and 3 days off plus fulvestrant 500 mg on days 1 and 15 of cycle 1 and then every 4 weeks, or to fulvestrant in the same dose and schedule plus placebo.
 

Results

The dual primary endpoint was investigator assessed PFS in both the overall population and in those with AKT pathway alterations. The median PFS in the overall population was 7.2 months with the combination, compared with 3.6 months for fulvestrant alone, translating into an adjusted hazard ratio for progression of 0.60 (P < .001).

In the pathway-altered population, the median PFS was 7.3 months with capivasertib/fulvestrant vs. 3.1 months with fulvestrant placebo, which translated into an adjusted hazard ratio for progression on the combination of 0.50 (P < .001).

An exploratory analysis of PFS among patients either without pathway alterations or unknown AKT status showed median PFS of 7.2 months and 3.7 months, respectively, with a hazard ratio of 0.70.

An analysis of benefit by subgroups in the overall population showed that the balance tipped in favor of the combination in nearly all categories, including among patients with or without liver metastases and with or without prior CDK4/6 inhibitor use.

Among patients with measurable disease at baseline the combination was associated with objective response rates (ORR) of 22.9% in the overall population and 28.8% in the pathway-altered population. The respective ORR for fulvestrant/placebo were 12.2% and 9.7%.

Overall survival data were not mature at the time of data cutoff, but showed trends favoring capivasertib plus fulvestrant in both the overall and AKT-pathway-altered population.

There were four fatal adverse events in the combination arm (acute myocardial infarction, cerebral hemorrhage, pneumonia aspiration, and sepsis), and one in the fulvestrant alone arm (COVID-19).

The most common grade 3 or greater adverse events among patients treated with the combination were rash (12.1%), diarrhea (9.3 %), and hyperglycemia (2.3%). In all, 13% of patients randomized to capivasertib/fulvestrant discontinued therapy due to adverse events, compared with 2.3% of patients assigned to fulvestrant/placebo.

Dr. Turner said that the overall adverse event profile with the combination was manageable and consistent with data from previous studies.
 

‘Clinically relevant benefit’

Invited discussant Fabrice André, MD, PhD, of Gustave Roussy Cancer Center in Villejuif, France, noted that the CAPItello-291 study is one of the first randomized trials enriched with patients whose tumors are resistant to CDK4/6 inhibitors.

“What are the take-home messages? First, there is a clinically relevant benefit in the overall population and in the PIK3CA mutant/AKT/PTEN altered population,” he said.

He noted that the exploratory analysis showed a small clinical benefit with an impressive hazard ratio but broad confidence interval in patients with biomarker-negative tumors, and noted that the study lacked either circulating tumor DNA analysis or exploration of other mechanisms of AKT pathway alteration.

The study was funded by AstraZeneca. Dr. Turner has served on the advisory board for AstraZeneca, and his institution has received research funding from the company. Dr. Andre disclosed fees to his hospital on his behalf from AstraZeneca, Daiichi Sankyo, Sanofi, Pfizer, Lilly, and Roche.

AT ASH 2022 NEW ORLEANS – Children with Hodgkin lymphoma can be cured with intensive chemotherapy, radiation, and other modalities, but a large majority of those who survive into adulthood then pay a high price in terms of accelerated aging and neurocognitive impairment.

The research findings emerged from a study of nearly 500 individuals in their late 30s, of whom 215 were adult survivors of pediatric Hodgkin lymphoma (HL) and 282 were community controls.

The results showed that HL survivors had a higher epigenetic age relative to their chronological age, compared with controls, translating into epigenetic age acceleration over chronological age equivalent to a mean of 7.7 years.

In addition, this accelerated epigenetic aging in HL survivors was accompanied by neurocognitive deficits, including declines in visual-motor processing, short-term memory, verbal learning and recall, and executive function.

“We found that biologic aging is associated with long-term neurocognitive impairment in Hodgkin lymphoma survivors,” commented lead author AnnaLynn M. Williams, PhD, of the Wilmot Cancer Institute at the University of Rochester (N.Y.) “Specifically, we see strong and consistent associations with memory impairment, which suggests that biologic aging is likely related to cognitive aging.”

Dr. Williams presented the findings at the annual meeting of the American Society of Hematology.

“Our hope is that this biomarker may help us identify those survivors most at risk for early-onset cognitive aging and might actually help us gauge a preclinical response to interventions, so that we can see efficacy sooner than some other endpoints,” she said in a media briefing prior to presenting the data.

“This is an area that is very near and dear to my heart,” commented ASH President Jane N. Winter, MD, from Northwestern University, Chicago.

“Pediatricians have been very much wedded to very intensive therapies and intend to incorporate radiation more frequently in their treatment strategies for children than we do in adults,” she said. In addition, “we are very much focused on the long-term consequences of mediastinal radiation causing breast cancer in adults who were treated as young adults or children for Hodgkin lymphoma, but now we’re shedding a light on the neurocognitive deficits, which I think are underappreciated.”

Such HL therapies may exert a significant long-term impact on a patient population “that we otherwise cure,” Dr. Winter commented, pointing to a study by investigators in Germany that showed high unemployment levels among adult survivors of childhood HL, compared with the general population.

Also reacting to Dr. Williams’ findings, Catherine Bollard, MD, of the Center for Cancer and Immunology Research at Children’s National Research Institute in Washington, D.C., said: “My concern actually is that even today, in pediatrics, we’re still giving combined chemotherapy and radiation to the majority of the children with the more advanced disease, and that is not what is happening for the treatment of adult Hodgkin disease.”

She noted that there are now many immune-based therapies available for Hodgkin lymphoma that could soon obviate the need for chemotherapy.
 

Long-term complications

Dr. Williams and colleagues had previously reported that, compared with their healthy siblings, long-term survivors of HL had significantly higher risk (P < .05 for all comparisons) of neurocognitive impairment, anxiety, depression, unemployment, and impaired physical/mental quality of life.

In the current study, they looked specifically at epigenetic aging, and asked all participants to complete a comprehensive neuropsychological battery of tests.

The 215 trial participants who were survivors of pediatric HL came from the St Jude Lifetime Cohort. The mean patient age was 39, and the survivors were an average of 25 years out from their initial diagnosis.

The mean age of the 282 community controls was 36 years. Both the cohort and the controls were all European ancestry.

All participants provided a blood sample. The investigators performed genome-wide methylation studies on DNA derived from peripheral blood mononuclear cells (PBMC), and used the data to calculate epigenetic age according to a biomarker called DNAm PhenoAge. Also known as “Levine’s Clock,” this epigenetic biomarker of aging for life span and health span was developed by Morgan E. Levine, PhD, and colleagues at the University of California, Los Angeles, and other centers.

Dr. Williams and her team determined epigenetic age acceleration by calculating the difference between epigenetic and chronological age, with a higher epigenetic accelerated age suggesting an older biological age relative to the patient’s actual age.

As noted above, they found that HL survivors had a significantly higher epigenetic accelerated age, compared with controls, equivalent to a mean difference of 7.7 years (P < .001).

More than 80% of the survivors had some degree of accelerated aging, compared with only 23% of controls.

HL survivors with higher degrees (second and third tertiles) of accelerated aging had significantly worse visual-motor processing speed compared with survivors in the first (lowest) tertile, with survivors in the second tertile performing on average 0.42 standard deviations worse (P = .005) and those in the third tertile performing 0.55 SD worse (P < .001).

In addition, relative to first tertile survivors, those in the second and third tertiles performed worse on short-term memory, with a decrease of –0.42 SD (P = .011) and 0.59 SD (P < .001), respectively.

HL survivors in the third tertile performed worse than those in the other tertiles on measures of verbal learning (P =.007) and long-term verbal recall (P = .005), and those in the second or third tertiles had an average decline of 0.4 SD, compared with those in first tertile on verbal fluency, a measure of executive function.

The declines in neurocognitive measures among survivors were relatively small but clinically significant, Dr. Williams said, and were likely to prove troublesome for patients.

Dr. Williams added that she and her colleagues are currently compiling data on a comparison of neurocognitive scores between cohort members and control, for future publication, “but I can say that, in the majority of measures that are reported on, survivors do worse.”

The investigators are planning expansion of DNA methylation profiling in the St. Jude Lifetime Cohort and will follow survivors prospectively to look for changes in epigenetic acceleration and how those changes might predict who is most at risk for neurocognitive decline.

The study was supported by grants from the National Cancer Institute. Dr. Williams, Dr. Winter, and Dr. Bollard all reported no relevant financial relationships.

HL survivors with higher degrees (second and third tertiles) of accelerated aging had significantly worse visual-motor processing speed compared with survivors in the first (lowest) tertile, with survivors in the second tertile performing on average 0.42 standard deviations worse (P = .005) and those in the third tertile performing 0.55 SD worse (P < .001).

In addition, relative to first tertile survivors, those in the second and third tertiles performed worse on short-term memory, with a decrease of –0.42 SD (P = .011) and 0.59 SD (P < .001), respectively.

HL survivors in the third tertile performed worse than those in the other tertiles on measures of verbal learning (P =.007) and long-term verbal recall (P = .005), and those in the second or third tertiles had an average decline of 0.4 SD, compared with those in first tertile on verbal fluency, a measure of executive function.

The declines in neurocognitive measures among survivors were relatively small but clinically significant, Dr. Williams said, and were likely to prove troublesome for patients.

Dr. Williams added that she and her colleagues are currently compiling data on a comparison of neurocognitive scores between cohort members and control, for future publication, “but I can say that, in the majority of measures that are reported on, survivors do worse.”

The investigators are planning expansion of DNA methylation profiling in the St. Jude Lifetime Cohort and will follow survivors prospectively to look for changes in epigenetic acceleration and how those changes might predict who is most at risk for neurocognitive decline.

The study was supported by grants from the National Cancer Institute. Dr. Williams, Dr. Winter, and Dr. Bollard all reported no relevant financial relationships.

NEW ORLEANS – Save lives; save money. What’s not to love? That’s the claim made for a proposed nationwide data bank on alloantibodies, which develop in response to foreign red blood cells in individuals who undergo repeated blood transfusions. They can occur after pregnancy or transplants, as well as in patients with sickle cell disease.

A central repository of data on alloantibodies would save lives by preventing serious immune reactions among patients with sickle cell disease and other maladies, and would save costs associated with hospitalization for serious and potentially fatal infusion reactions, say the creators of a mathematical model demonstrating the clear value of such a databank.

“The findings from our model are pretty definitive,” said George Goshua, MD, MSc, of Yale University, New Haven, Conn. “Despite very conservative assumptions, our results still show a huge financial benefit to having a system in place to serve as a preventive net that catches patients before they have to go through a delayed hemolytic transfusion reaction (DHTR).”

Dr. Goshua presented the study at the American Society of Hematology annual meeting. The proposed registry would significantly reduce the risk that transfusion-dependent patients, and others who require occasional transfusions, would develop complications requiring hospitalization, he said.

A similar registry has been up and running in the Netherlands for 15 years, he said at a press briefing.

Briefing moderator Catherine Bollard, MD, of the Center for Cancer and Immunology at Children’s National Research Institute in Washington, asked Dr. Goshua why such an exchange hasn’t been started in the United States already.

“I will say first that our European colleagues are far ahead in terms of preventative care,” he replied.

“On top of that, there’s a unique environment in the United States – and this dates back about 15 years now – where we are almost allergic to putting costs on benefits, that is, attaching a cost value to a benefit that a population can gain,” Dr. Goshua said. “So in this context, there hasn’t been an analysis that shows that this [exchange] actually makes sense, but I think it’s one of those analyses kind of showing people that the sky is blue but proving it quantitatively.”

Dr. Bollard said that the potential beneficial impact of such an exchange “is huge,” but it would “require upfront expenditure to actually realize these massive gains you will get down the road for these patients.”
 

Would be cost-effective

Although hospitals and transfusion centers check donated blood against an individual patient’s alloantibody profile, that information is usually kept in localized records and is not typically shared across health systems nationwide.

It’s different in the Netherlands, where the Transfusion Register of Irregular Antibodies and Cross-match Problems (TRIX) was launched in 2007. Under this system, transfusion laboratories register the presence of irregular red blood cell alloantibodies for their patients and can consult the database for information that is relevant for pretransfusion testing.

To see whether such a system, if implemented in the United States, would satisfy even the most parsimonious administrator or insurer, Dr. Goshua and colleagues created a computer simulation.

They estimated age- and gender-adjusted quality-adjusted life years (QALYs) for patients living with sickle cell disease, who typically require frequent transfusions and are thus especially at risk for developing alloantibodies and immune reactions from repeat exposures to the blood of others.

The model included age- and gender-adjusted costs based on 10 years of claims data, with the assumption that equal numbers of male and females would be in the sample.

The model estimated that by reducing DHTR incidence and DHTR-specific mortality in 20% to 44% of alloimmunized patients (a very conservative estimate, according to Dr. Goshua), the existence of a U.S. exchange would result in a gain of between 7,140 and 15,710 QALYs.

Assuming a willingness to pay up to $100,000 per QALY, a commonly used threshold in economic analyses in the United States, the exchange (vs. no exchange) would be preferred in 100% of 10,000 different iterations of a cost-effectiveness acceptability curve, Dr. Goshua said.

Even if the lifetime operational costs of such an exchange exceeded $600 million, it would still be cost-effective, and the net monetary benefit to the U.S. economy would be $0.7 billion, the authors found.

And although the model was limited to patients with sickle cell anemia, many other alloimmunized patients would be likely to benefit from such an exchange, including women with a prior pregnancy, and patients with autoimmunity, myelodysplastic syndrome, or beta-thalassemia, Dr. Goshua said.

The study was supported by the American Society of Hematology, the Yale School of Medicine, and Yale Center. Dr. Goshua and Dr. Bollard reported no relevant financial relationships.

Nearly 90% of beta-thalassemia patients were transfusion free for up to 8 years after treatment with the one-time gene therapy betibeglogene autotemcel (beti-cel), according to a report at the American Society of Hematology annual meeting.

Surveyed at 3 years, patients also reported ongoing benefits from treatment, including positive impacts on employment, school attendance, and physical activity, according to a second report.

The findings address a major question about betibeglogene autotemcel: Its durability. The therapy is priced at over $2 million per treatment, based on the premise that it will benefit patients in the long-term, in part by offsetting the cost of ongoing transfusions. Therefore, proof of long-standing benefit is important.

The Food and Drug Administration approved betibeglogene autotemcel in August 2022 for children and adults with transfusion dependent beta-thalassemia, a condition that causes patients to have absent or reduced levels of hemoglobin due to mutations in the beta-globin gene. Patients typically require transfusions every 2-5 weeks.

The treatment inserts functional copies of the mutated gene into the patients’ hematopoietic stem cells via a replication-defective lentivirus. The cells are then transfused back into the patient.

As of August 2021, 63 patients had undergone treatment and been followed for a median of 41.4 months. So far, durability looks solid.

“We now have up to 8 years efficacy and safety follow-up” with beti-cel. “Patients experience durable transfusion independence,” said Mark Walters, MD, a pediatric hematologist/oncologist at the University of California, San Francisco, who presented the long-term efficacy data at the meeting.

Overall, 89.5% of patients (34/38) in phase 3 testing achieved transfusion independence, meaning that they had hemoglobin levels of at least 9 g/dL without transfusions for a year or more.

The response rate was an improvement over phase 1/2 testing, in which 68% of subjects (15/22) became transfusion free. Improvements in the manufacturing process led to better outcomes in phase 3, Dr. Walters said.

As for quality of life (QoL), improvement “continues through 3 years following treatment,” said Franco Locatelli, MD, a pediatric hematologist/oncologist at Catholic University of the Sacred Heart, Rome, who led the QoL study.

When patients who achieved transfusion independence were surveyed 3 years after treatment, 93% of adults were employed or able to seek employment, up from 67% before treatment. School absences were down among children, almost half of subjects no longer needed symptom management, and 81% reported improvements in physical activity.

There were also improvements on various quality of life scales, including in physical functioning and mental health.

Patient age and underlying thalassemia genotype had no impact on the likelihood of transfusion independence. Those who achieved it also had reductions in markers of ineffective erythropoiesis and iron overload.

On multivariate analysis, the greatest predictor of transfusion independence was having at least 62% of cells transduced prior to reintroduction to the patient.

As for adverse events, seven subjects (11%) developed severe veno-occlusive liver disease that resolved with supportive care. Mucositis and febrile neutropenia are also a concern and related to the busulfan conditioning regimen.

No malignancies, insertional oncogenesis, or lentivirus replication have been observed.

The studies were funded by beti-cel maker Bluebird Bio, and many of the investigators are employees. Others reported ties to Bluebird and a range of other companies. Among his industry ties, Dr. Locatelli is a speaker for Bluebird. Dr. Walters also had industry relationships, but didn’t report any ties to Bluebird.

San Antonio – A 16-gene molecular signature may identify patients with breast cancer who are at risk for locoregional recurrence, as well as those who can be safely spared from breast radiation following breast-conserving surgery, an international team of investigators said.

In combined data from three independent randomized trials grouped into a meta-analysis, patients who had low scores on the messenger RNA–based signature, dubbed “Profile for the Omission of Local Adjuvant Radiotherapy” (POLAR), derived only minimal benefit from radiotherapy following breast-conserving surgery. In contrast, patients with high POLAR scores had significant clinical benefit from adjuvant radiotherapy, reported Per Karlsson, MD, chief physician with the Sahlgrenska Comprehensive Cancer Center and the University of Gothenburg (Sweden). Dr. Karlsson reported his findings at the San Antonio Breast Cancer Symposium.

“To our knowledge, POLAR is the first genomic classifier that is not only prognostic but also predictive of radiotherapy benefit, showing a significant interaction between radiotherapy and the classifier,” he said. “These important retrospective findings warrant further investigation, including in contemporary clinical studies.”

Investigators with the Swedish SweBCG91RT trial (Swedish Breast Cancer Group 91 Radiotherapy), the Scottish Conservation (radiotherapy) Trial (SCT), and a trial from the Princess Margaret Cancer Hospital in Toronto, collaborated on improving and validating the POLAR signature, which was originally developed for use in the SweBCG91RT trial in patients with lymph node–negative breast cancer who underwent breast-conserving surgery. The patients were randomized to whole breast irradiation or no radiotherapy.

To develop the signature, researchers collected tumor blocks from 1,004 patients, and extracted RNA from the samples. Gene expression data were obtained from primary tumors of 764 patients. The subset of 597 patients with estrogen receptor–positive, HER2-negative tumors (ER+/HER2–) who did not receive systemic therapy were divided into a training set with 243 patients, and a validation cohort with 354 patients.

They identified a total of 16 genes involved in cellular proliferation and immune response, and then validated the signature using retrospective data from three clinical trials of patients randomized to radiotherapy or no radiation following breast-conserving surgery.

Of 623 patients with node-negative ER+/HER2– tumors who were included in the meta-analysis, 429 patients were found to have high POLAR scores. These patients benefited from adjuvant radiation therapy after breast-conserving surgery with a 10-year cumulative incidence of low risk of locoregional recurrence ranging from 15% to 26% for those who were not treated with radiation therapy, compared with only 4%-11% percent for those who received radiation therapy (hazard ratio, 0.37; P < .001).

In contrast, among the 194 patients whose tumors had POLAR low scores, there was no apparent benefit from radiation therapy with a nonsignificant HR of 0.92 (P = .832).

In Cox proportional hazard models for time to locoregional recurrences for 309 patients who did not undergo radiation, POLAR scores were significantly prognostic for recurrence, with a HR of 1.53 (P < .001) in univariable analysis, and 1.43 (P = .005) in multivariable analysis controlling for age, tumor size, tumor grade and molecular groupings.
 

New modalities may make findings less relevant

Alphonse Taghian, MD, PhD, a breast radiation oncologist with Mass General Cancer Center, Boston, who was not involved in the study, said there have been major changes in radiation therapy since the studies used for development of the POLAR signature were performed. For example, the Scottish Conservation Trial ran from 1985 to 1991, while the SweBCGR91RT trial and Princess Margaret trial were both conducted in the 1990s.

He noted that patients in those studies would likely experience more morbidities from radiation than patients treated with more recent modalities such as intensity modulated radiation therapy, and that patients treated 30 years ago would have to put up with lengthy fractionation schedules that required daily trips to the hospital over as long as 6 weeks, whereas a majority of patients can now be treated with hypofractionated radiation that can be performed in a much shorter time and with minimal comorbidities.

He acknowledged, however, that “it will help to have a signature proved, confirmed, or validated retrospectively with a different set of data.”

Dr. Taghian also said that it would be helpful to have more data about the age of patients, because omitting radiation is more common for elderly patients than it is for younger patients.

“It will maybe be beneficial to look at this signature in patients that we think might not need radiation,” he said.

The study was supported by the Swedish Cancer Society, Swedish Research Council, King Gustav 5 Jubilee Clinic Foundation, the ALF Agreement of the Swedish government, PFS Genomics, and Exact Sciences. Dr. Karlsson has pending patents with and receives royalties from Exact Sciences and PreludeDX. Dr. Taghian reported having no relevant disclosures.

In Cox proportional hazard models for time to locoregional recurrences for 309 patients who did not undergo radiation, POLAR scores were significantly prognostic for recurrence, with a HR of 1.53 (P < .001) in univariable analysis, and 1.43 (P = .005) in multivariable analysis controlling for age, tumor size, tumor grade and molecular groupings.
 

New modalities may make findings less relevant

Alphonse Taghian, MD, PhD, a breast radiation oncologist with Mass General Cancer Center, Boston, who was not involved in the study, said there have been major changes in radiation therapy since the studies used for development of the POLAR signature were performed. For example, the Scottish Conservation Trial ran from 1985 to 1991, while the SweBCGR91RT trial and Princess Margaret trial were both conducted in the 1990s.

He noted that patients in those studies would likely experience more morbidities from radiation than patients treated with more recent modalities such as intensity modulated radiation therapy, and that patients treated 30 years ago would have to put up with lengthy fractionation schedules that required daily trips to the hospital over as long as 6 weeks, whereas a majority of patients can now be treated with hypofractionated radiation that can be performed in a much shorter time and with minimal comorbidities.

He acknowledged, however, that “it will help to have a signature proved, confirmed, or validated retrospectively with a different set of data.”

Dr. Taghian also said that it would be helpful to have more data about the age of patients, because omitting radiation is more common for elderly patients than it is for younger patients.

“It will maybe be beneficial to look at this signature in patients that we think might not need radiation,” he said.

San Antonio – A 16-gene molecular signature may identify patients with breast cancer who are at risk for locoregional recurrence, as well as those who can be safely spared from breast radiation following breast-conserving surgery, an international team of investigators said.

In combined data from three independent randomized trials grouped into a meta-analysis, patients who had low scores on the messenger RNA–based signature, dubbed “Profile for the Omission of Local Adjuvant Radiotherapy” (POLAR), derived only minimal benefit from radiotherapy following breast-conserving surgery. In contrast, patients with high POLAR scores had significant clinical benefit from adjuvant radiotherapy, reported Per Karlsson, MD, chief physician with the Sahlgrenska Comprehensive Cancer Center and the University of Gothenburg (Sweden). Dr. Karlsson reported his findings at the San Antonio Breast Cancer Symposium.

“To our knowledge, POLAR is the first genomic classifier that is not only prognostic but also predictive of radiotherapy benefit, showing a significant interaction between radiotherapy and the classifier,” he said. “These important retrospective findings warrant further investigation, including in contemporary clinical studies.”

Investigators with the Swedish SweBCG91RT trial (Swedish Breast Cancer Group 91 Radiotherapy), the Scottish Conservation (radiotherapy) Trial (SCT), and a trial from the Princess Margaret Cancer Hospital in Toronto, collaborated on improving and validating the POLAR signature, which was originally developed for use in the SweBCG91RT trial in patients with lymph node–negative breast cancer who underwent breast-conserving surgery. The patients were randomized to whole breast irradiation or no radiotherapy.

To develop the signature, researchers collected tumor blocks from 1,004 patients, and extracted RNA from the samples. Gene expression data were obtained from primary tumors of 764 patients. The subset of 597 patients with estrogen receptor–positive, HER2-negative tumors (ER+/HER2–) who did not receive systemic therapy were divided into a training set with 243 patients, and a validation cohort with 354 patients.

They identified a total of 16 genes involved in cellular proliferation and immune response, and then validated the signature using retrospective data from three clinical trials of patients randomized to radiotherapy or no radiation following breast-conserving surgery.

Of 623 patients with node-negative ER+/HER2– tumors who were included in the meta-analysis, 429 patients were found to have high POLAR scores. These patients benefited from adjuvant radiation therapy after breast-conserving surgery with a 10-year cumulative incidence of low risk of locoregional recurrence ranging from 15% to 26% for those who were not treated with radiation therapy, compared with only 4%-11% percent for those who received radiation therapy (hazard ratio, 0.37; P < .001).

In contrast, among the 194 patients whose tumors had POLAR low scores, there was no apparent benefit from radiation therapy with a nonsignificant HR of 0.92 (P = .832).

NASHVILLE, TENN. – Targeting relevant sleep problems for patients with refractory temporal lobe epilepsy (TLE) improves cognition, results of a new, double-blind, randomized controlled trial suggest.

Study findings show significant improvement in REM sleep and language scores for patients with TLE who took the cholinesterase inhibitor donepezil and better slow-wave sleep and memory scores for those who took the sleep aid zolpidem.

The results are “intriguing and surprising” and should encourage clinicians to “look for sleep abnormalities” in patients with uncontrolled epilepsy, study investigator Garima Shukla, MBBS, MD, DM, professor, division of neurology, department of medicine, Queens University, Kingston, Ont., told this news organization.

Daytime sleepiness could be a red flag in these patients, although it could mean they just have treatable sleep apnea, said Dr. Shukla. “But if they have very poor slow-wave sleep, we could try increasing its percentage by prescribing zolpidem.”

The findings were presented at the annual meeting of the American Epilepsy Society.

Sleep, cognitive disturbances common

Sleep disturbances and cognitive disturbances are common among patients with TLE. Executive function is affected in almost all patients with refractory epilepsy, and it’s “super common” that TLE patients have memory disturbances, said Dr. Shukla.

The study included 108 patients with refractory TLE who were awaiting surgery. The patients, who had no severe comorbidities, were randomly assigned to three groups; the final number in each group was 36.

Patients in group 1 received donepezil 10 mg in the morning and a placebo at night. (Donepezil is used to treat memory loss associated with Alzheimer’s disease.)

Those in group 2 received a placebo in the morning and zolpidem 6.25 mg at night. Group 3 patients received a placebo in the morning and again at night.

The mean age of the patients was 25.4, 27.1, and 27.6 years, and the percentage of men was 63.8%, 72.2%, and 63.8% in groups 1, 2, and 3, respectively.

In all groups, patients had been experiencing about three seizures per month. The median number of antiseizure medications was two in group 1 and three in both groups 2 and 3.

Researchers evaluated sleep using the Pittsburgh Sleep Quality Index, the Epsworth Sleepiness Scale, and video polysomnography and electroencephalography.

To assess executive function, they used the Trail A & B, Stroop, and forward and backward Digit Span tests. For memory, they used the Weschler Memory Scale, and for language, the Western Aphasia Battery. They conducted follow-up evaluations at 6 months.

The results showed significant improvement in the percentage of rapid eye movement (REM) sleep in group 1 (from 14.81 at baseline to 18.21 at 6 months). In this group, the number of patients whose REM sleep percentage was less than 15 dropped significantly from 29 (of 36) to 10.

In group 2, sleep-onset latency significantly improved, and the percentage of N3 (slow-wave) sleep stage increased significantly from 25.27 to 28.74.

Regarding cognitive outcomes, backward Digit Span was significantly improved for patients in group 1. In this group, there was also a significant reduction in the time taken for Stroop A test, and there was significant improvement in language.

In group 2, there was a significant improvement in verbal and visual memory scores. There were no significant changes in group 3.

The increase in REM sleep percentage in group 1 strongly correlated with increased language and executive function scores. Similarly, in group 2, the increase in N3 sleep percentage strongly correlated with an increase in verbal memory scores.

On the basis of these observations, giving a small dose of zolpidem to a patient with “acceptable” REM sleep but very little slow-wave sleep may boost the patient’s non-REM sleep, said Dr. Shukla. “By improving non-REM sleep percentage, we will possibly help memory consolidation.”

Dr. Shukla sees this study as “a stepping-stone” to larger, multicenter trials testing “the effect of zolpidem through its impact on improving non-REM sleep percentage consolidation and its impact on memory.”

This idea veers somewhat from the traditional idea that REM sleep plays a greater role in memory consolidation, she said. “We actually found it correlates very well with language, which we have also seen in some of our anecdotal case reports.”

Patients whose language scores are very poor are “the population I would pick to target REM sleep through donepezil,” said Dr. Shukla.

‘Encouraging’ findings

Commenting for this news organization, Daniel Goldenholz, MD, PhD, assistant professor, Harvard Beth Israel Deaconess Medical Center, Boston, praised the study design.

“It allows for comparison between different treatments, as well as a placebo control group,” said Dr. Goldenholz, who added, “There appears to be good follow-up” as well.

The fact that medication may provide some cognitive benefit for patients with TLE is “very encouraging,” he said.

He noted many patients with TLE complain of memory or language problems. “So, this is a major concern.”

However, he cautioned about side effects. “Putting all temporal lobe epilepsy patients who say that they have memory problems or language problems on these medications could have some serious consequences.”

The study was funded by a Department of Health Research grant from the government of India. Dr. Goldenholz is on the advisory board for epilepsy AI, Eyzs, and Magic Leap.

NASHVILLE, TENN. – A study of more than 4 million births over 20 years in five Scandinavian countries has reported that three antiseizure medications should be used with caution in women of child-bearing age because they were associated with low birth weights.

In results presented at the annual meeting of the American Epilepsy Society, Jakob Christensen, MD, DSc, PhD, a professor at Aarhus University Hospital in Denmark, said that the study found that carbamazepine, oxcarbazepine, and topiramate were associated with low birth weight and increased risk of infants being born small for gestational age.

• Carbamazepine, 1.44 (95% confidence interval [CI], 1.21-1.71).
• Oxcarbazepine, 1.32 (95% CI, 1.03-1.69).
• Topiramate, 1.60 (95% CI, 1.15-2.24).
• Pregabalin, 1.23 (95% CI, 1.02-1.48).
• Clobazam, 4.36 (95% CI, 1.66-11.45).

The odds ratios for being born small for gestational age were:

• Carbamazepine, 1.25 (95% CI, 1.11-1.41).
• Oxcarbazepine, 1.48 (95% CI, 1.27-1.73).
• Topiramate, 1.52 (95% CI, 1.20-1.91).

“Prenatal exposure to carbamazepine, oxcarbazepine, and topiramate were associated with all estimates of adverse birth weight outcomes, thus confirming results from preclinical studies in animals and previous smaller studies in humans,” Dr. Christensen said.

He noted a lack of evidence for newer medications because their use was relatively low over the 20 years of the study. “However, for drugs like lamotrigine where we have a high number of exposed children, the finding of no association with low birth weight is reassuring, indicating the drug is safe,” Dr. Christensen said.
 

Use with caution

This study adds supportive evidence for expanding the list of antiseizure medications associated with small for gestational age infants, Elizabeth Gerard, MD, director of the Women with Epilepsy Program and associate professor of neurology at Northwestern University in Chicago, said in an interview.

“Previous clinical trials demonstrated that topiramate and zonisamide as well as phenobarbital were associated with small for gestational age,” she said. “This study added to the list carbamazepine and oxcarbazepine. Previously it wasn’t clear from clinical data but there were some hints that carbamazepine and oxcarbazepine might be associated with small for gestational age, but this is the first study to present robust data that carbamazepine and oxcarbazepine are associated with small for gestational age infants as well.”

She noted that these drugs can be used cautiously in women of child-bearing age and pregnant women. “I think these lines of evidence suggest that women with epilepsy should be more carefully monitored, at least with these high-quality, standard-of-care drugs, for fetal growth monitoring and perhaps most of them, especially those on at-risk drugs, should have detailed growth gradings,” Dr. Gerard said. Pregnant women on these antiseizure medications should have ultrasound beginning at 24 weeks gestation to monitor fetal growth, she said.

The NordForsk Nordic Program and Health and Welfare and the Independent Research Fund Denmark provided funding for the study. Dr. Christensen disclosed financial relationships with Union Chimique Belge Nordic and Eisai. Dr. Gerard disclosed relationships with Xenon Pharmaceuticals and Eisai.

NEW ORLEANS – A novel, off-the-shelf antibody, talquetamab, has shown high response rates among patients with heavily pretreated multiple myeloma in both phase 1 and now phase 2 studies, which have been submitted for approval.

“Talquetamab is a novel agent directed against a new antigen target in myeloma,” explained lead investigator Ajai Chari, MD, of Icahn School of Medicine at Mount Sinai in New York.

The product has demonstrated “a response rate of 73% to 74% with both weekly and every 2-week schedules in a heavily treated patient population. Even in those patients with prior T-cell redirection, we see a 63% response rate,” said Dr. Chari, who reported the data at the American Society of Hematology annual meeting.

It is encouraging to see high response rates among patients with disease that is refractory to multiple prior lines of therapy, and the results suggest that talquetamab may buy time for patients with few other options, said Stephanie Lee, MD, MPH, of the Fred Hutchinson Cancer Center in Seattle, and a former ASH president.

“It looks like there are responses even in people who are heavily pretreated and have had other agents similar to it, “ she said. “We hear about ‘penta-refractory’ [disease] and everything, and I think we’re going to start hearing about ‘octo-refractory’ and ‘deci-refractory,’ and those things. It’s really exciting [to see these responses],” she said. Dr. Lee moderated a media briefing prior to Dr. Chari’s discussion of the data.

Talquetamab is a bispecific antibody directed against a novel target with the prosaic name of “G protein–coupled receptor, family C, group 5, member D” or simply GPRC5D. The antigen is a so-called “orphan” receptor with an unidentified ligand. The receptor is expressed in malignant plasma cells, making it a particularly attractive target for the treatment of patients with multiple myeloma.

“It’s important to pick the right target for these [patients] and GPRC5D is a good candidate for that because it’s highly expressed on myeloma cells but spares normal tissues, in particular the hematopoietic stem cells for the precursors to their blood,” Dr. Chari said.

The new drug could be available next year. The manufacturer, Janssen, announced last week that it had submitted an approval application with the Food and Drug Administration for talquetamab use in the treatment of patients with relapsed or refractory multiple myeloma.

The clinical results so far “indicate the potential of this treatment for heavily pretreated patients who have exhausted currently approved therapies,” Dr. Chari said in a statement.
 

MonumenTAL study

Dr. Chari and colleagues recently reported results of the phase 1 MonumenTAL-1 study in The New England Journal of Medicine. At ASH 2022, they reported phase 2 results from the same study, including some patients carried over from phase 1, but also a subgroup of patients with prior exposure to either chimeric antigen receptor T-cell (CAR-T) therapy or other bispecific T cell-engaging antibodies.

In the phase 1 dose-escalation study published in NEJM,  the response rates among patients who had a median of six prior lines of therapy ranged from 64% to 70%. The drug was delivered in this phase at a variety of dose levels and schedules, and both intravenously and subcutaneously.
 

Three cohorts, two doses

The phase 2 study enrolled patients who had a minimum of three prior lines of therapy including a proteasome inhibitor, immunomodulating agent, and anti-CD38 antibody, and who had good-to-fair performance status.

There were three cohorts. The first cohort comprised 21 patients from phase 1 and 122 from phase 2 who received talquetamab at a dose of 0.4 mg/kg subcutaneously once weekly. These patients were allowed to have received prior therapy with an antibody-drug conjugate (ADC) targeted against B-cell maturation antigen (BCMA), but could not have received a prior T-cell redirection therapy.

The second cohort comprised 36 patients in phase 1 and 109 in phase 2 who were treated with 0.8 mg/kg subcutaneously every 2 weeks. These patients had the same prior therapy allowances and restrictions as the first cohort.

The third cohort comprised 17 patients in phase 1 plus 34 patients in phase 2 who had received either CAR T-cell receptor therapy or a different bispecific T-cell engager. These patients received either 0.4 mg/kg weekly subcutaneous talquetamab, or 0.8 mg/kg every 2 weeks.
 

Phase 2 results

The overall response rate (ORR)  among patients treated at 0.4 mg/kg weekly was 74.1%, including 23.8% stringent complete responses (sCR), 9.8% complete response (CR), 25.9% very good partial responses (VGPR) and 14.7% partial responses (PR).

The ORR among patients treated at the 0.8 mg/kg every 2 week dose was 73.1%, consisting of 20% sCR, 12.4% CR, 24,8% VGPR, and 15.9% PR.

The response rates were consistent across subgroups, including baseline International Staging System (ISS) stage III disease, baseline cytogenetic risk, number of prior therapies, degree of refractoriness to prior therapy, and prior exposure to the anti-BCMA antibody belantamab (except patients with baseline plasmacytomas).

The median durations of responses were 9.3 months and 13 months in the 0.4 and 0.8 mg/kg doses, respectively. The median duration of response was not reached among patients who had achieved a CR or better in either dosing group.
 

Safety profile

Most adverse events of grade 3 or 4 were cytopenias, including anemia, neutropenia, lymphopenia, and thrombocytopenia. These adverse events were generally limited to the first three cycles, and less than a third of all cytopenias were grade 3 or greater.

Infection occurred in 57.3% of patients treated at 0.4 mg/kg weekly and 50.3% treated at 0.8 mg/kg every 2 weeks. Of these infections, 16.8% and 11.7%, respectively, were grade 3 or 4.

Opportunistic infections were seen in 3.5% of patients treated at 0.4 mg/kg and 2.8% of those treated at 0.8 mg/kg.

Taste alterations (dysgeusia) occurred in nearly half of patients in each dosing group. Dysgeusia was managed with supportive care, including hydration, and in some cases  with dose reductions.

Immune effector cell-associated neurotoxicity syndrome (ICANS) was observed in 10% to 11% of patients, but most of these events were grade 1 or 2.
 

What’s next?

At the briefing, this news organization asked Dr. Chari whether, given the evident efficacy and relative safety of this agent, it could be moved up higher in the therapeutic lines and combined with other agents such as proteasome inhibitors (bortezomib et al.), immunomodulators (lenalidomide and others) and CD38-directed antibodies (daratumumab, etc.)

Dr. Chari replied that several studies combining talquetamab with agents in all of these classes and with other bispecific T-cell engagers are currently underway.

Dr. Chari disclosed consulting fees from Janssen, which supported the study. Dr. Lee has received clinical trial research funding from Amgen, AstraZeneca, Incyte, Kadmon, Novartis, Pfizer, Syndax, and Takeda and has served as a consultant to Incyte.

NEW ORLEANS – A gene therapy made headlines recently for becoming the most expensive pharmaceutical ever launched – the price tag was $3.5 million for a one-off treatment with etranacogene dezaparvovec (Hemgenix) for hemophilia B.

Another gene therapy, a treatment for sickle cell anemia now in late clinical development, is expected to come on the market soon. It, too, is expected to bear an exorbitant price tag.

Such potentially curative therapies put financial pressure on publicly and privately funded health insurance.

However, investigators said that the new treatment for patients with sickle cell disease (SCD) in the United States has the potential to be cost-effective. Those who analyzed the costs used a novel method that takes historical health inequities into account.

“When faced with costs of innovative, one-time-administered therapies, budgetary constraints, as we all know too well, can and have driven therapy availability or lack thereof for patients,” said George Goshua, MD, from the Yale University, New Haven, Conn., speaking here at the annual meeting of the American Society of Hematology.

“We believe that quantitative consideration of health inequities, in addition to the important quality considerations, may be an additional helpful metric in this decision-making context,” he said.

He noted that SCD predominantly affects Black Americans, “who have historically been a very marginalized population when it comes to health care.

“Our study shows that, when we compare the costs of gene therapy and existing standard-of-care treatment for SCD using a technique that accounts for historical health disparities, gene therapy could be an equitable therapeutic strategy for all patients with SCD, whether their disease is mild, moderate, or severe,” he said.

Commenting on the study for this news organization, Bosula Oluwole, MD, from the University of Washington, Seattle, who studies sickle cell disease but was not involved in this study, said the cost-analysis approach taken by Dr. Goshua and colleagues is interesting, but she added: “I think we still have a way to go in trying to fully understand the issue.

“When you look over time at the cost for a patient to get gene therapy vs. the standard of care, it might actually be beneficial to have the gene therapy,” Dr. Oluwole said.

She noted, however, that some patients start gene therapy for SCD at older ages and that it’s important to analyze whether the treatment can still be cost-effective or the best therapeutic option for such patients.
 

Adding a D to CEA

Dr. Goshua and colleagues at Yale University and the Harvard T.H. Chan School of Public Health in Boston conducted what they believe is the first study in hematology to use distributional cost-effectiveness analysis (DCEA), developed at the University of York, England.

A University of York website explains that DCEA “is a general umbrella term for economic evaluation studies that provide information about equity in the distribution of costs and effects as well as efficiency in terms of aggregate costs and effects. DCEA can provide distributional breakdowns of who gains most and who bears the largest burdens (opportunity costs) by equity-relevant social variables (e.g., socioeconomic status, ethnicity, location) and disease categories (e.g., severity of illness, rarity, disability).”

The technique can also employ equity weight to evaluate trade-offs between equity and efficiency, the website says.

As Dr. Goshua put it, equity weighting is “a way of quantifying how much we prioritize health care equity.”
 

QALYs considered

Dr. Goshua and colleagues included equity weight in an analysis of 10 years of data on annual health care costs for patients with SCD who were covered by private insurance and were treated with medications (for example, hydroxyurea), antibiotics, blood transfusion, and hematopoietic stem cell transplants. Sex and the frequency of hospitalizations for acute pain crises were factors in the Markov model they created.

The model assumes that a single course of gene therapy for SCD would cost $2.1 million. The estimate was based on the cost of U.S. Food and Drug Administration–approved gene therapies, and it was assumed that the therapy would result in permanent disease remission for all patients.

In addition, the model assumed that all eligible patients in the United States with SCD who are aged 12 years and older would be offered the gene therapy.

In their base-case analysis, gene therapy starting at age 12 would yield 25.5 discounted lifetime quality-adjusted life-years (QALYs) at a cost of $2.4 million, compared with 16.0 discounted lifetime QALYs at a cost of $1.1 million for standard care.

Under traditional cost-effectiveness calculations, the upper limit of the incremental cost-effectiveness ratio (ICER) is estimated to be $100,000 per QALY. Under this scenario, the ICER of gene therapy for SCD at $144,000 per QALY would be considered by health economists or insurers to be too steep a price to pay.

However, applying equity weighting to the formula would bring the price of gene therapy into the $1.4 million to $3 million range.

Dr. Goshua acknowledged that the study is limited by the assumption that gene therapy would be a one-time cost and that patients would not need to undergo repeat therapy or treatment for relapses.

Stephanie Lee, MD, MPH, from the Fred Hutchinson Cancer Center in Seattle, and a former ASH president, who moderated a briefing the day before Dr. Goshua presented his data, recommended that he and his colleagues use their technique to explore other health inequities, such as in the care of patients with multiple myeloma.

“There’s some evidence that Black patients are not using even the agents we have as [are] some of the other groups, so there may be some distributional inequities there as well,” she said.

The study was funded by ASH and the Yale School of Medicine. Dr. Goshua, Dr. Oluwole, and Dr. Lee have disclosed no relevant financial relationships.

“When faced with costs of innovative, one-time-administered therapies, budgetary constraints, as we all know too well, can and have driven therapy availability or lack thereof for patients,” said George Goshua, MD, from the Yale University, New Haven, Conn., speaking here at the annual meeting of the American Society of Hematology.

“We believe that quantitative consideration of health inequities, in addition to the important quality considerations, may be an additional helpful metric in this decision-making context,” he said.

He noted that SCD predominantly affects Black Americans, “who have historically been a very marginalized population when it comes to health care.

“Our study shows that, when we compare the costs of gene therapy and existing standard-of-care treatment for SCD using a technique that accounts for historical health disparities, gene therapy could be an equitable therapeutic strategy for all patients with SCD, whether their disease is mild, moderate, or severe,” he said.

Commenting on the study for this news organization, Bosula Oluwole, MD, from the University of Washington, Seattle, who studies sickle cell disease but was not involved in this study, said the cost-analysis approach taken by Dr. Goshua and colleagues is interesting, but she added: “I think we still have a way to go in trying to fully understand the issue.

“When you look over time at the cost for a patient to get gene therapy vs. the standard of care, it might actually be beneficial to have the gene therapy,” Dr. Oluwole said.

She noted, however, that some patients start gene therapy for SCD at older ages and that it’s important to analyze whether the treatment can still be cost-effective or the best therapeutic option for such patients.
 

Adding a D to CEA

Dr. Goshua and colleagues at Yale University and the Harvard T.H. Chan School of Public Health in Boston conducted what they believe is the first study in hematology to use distributional cost-effectiveness analysis (DCEA), developed at the University of York, England.

A University of York website explains that DCEA “is a general umbrella term for economic evaluation studies that provide information about equity in the distribution of costs and effects as well as efficiency in terms of aggregate costs and effects. DCEA can provide distributional breakdowns of who gains most and who bears the largest burdens (opportunity costs) by equity-relevant social variables (e.g., socioeconomic status, ethnicity, location) and disease categories (e.g., severity of illness, rarity, disability).”

The technique can also employ equity weight to evaluate trade-offs between equity and efficiency, the website says.

As Dr. Goshua put it, equity weighting is “a way of quantifying how much we prioritize health care equity.”
 

QALYs considered

Dr. Goshua and colleagues included equity weight in an analysis of 10 years of data on annual health care costs for patients with SCD who were covered by private insurance and were treated with medications (for example, hydroxyurea), antibiotics, blood transfusion, and hematopoietic stem cell transplants. Sex and the frequency of hospitalizations for acute pain crises were factors in the Markov model they created.

The model assumes that a single course of gene therapy for SCD would cost $2.1 million. The estimate was based on the cost of U.S. Food and Drug Administration–approved gene therapies, and it was assumed that the therapy would result in permanent disease remission for all patients.

In addition, the model assumed that all eligible patients in the United States with SCD who are aged 12 years and older would be offered the gene therapy.

In their base-case analysis, gene therapy starting at age 12 would yield 25.5 discounted lifetime quality-adjusted life-years (QALYs) at a cost of $2.4 million, compared with 16.0 discounted lifetime QALYs at a cost of $1.1 million for standard care.

Under traditional cost-effectiveness calculations, the upper limit of the incremental cost-effectiveness ratio (ICER) is estimated to be $100,000 per QALY. Under this scenario, the ICER of gene therapy for SCD at $144,000 per QALY would be considered by health economists or insurers to be too steep a price to pay.

However, applying equity weighting to the formula would bring the price of gene therapy into the $1.4 million to $3 million range.

Dr. Goshua acknowledged that the study is limited by the assumption that gene therapy would be a one-time cost and that patients would not need to undergo repeat therapy or treatment for relapses.

Stephanie Lee, MD, MPH, from the Fred Hutchinson Cancer Center in Seattle, and a former ASH president, who moderated a briefing the day before Dr. Goshua presented his data, recommended that he and his colleagues use their technique to explore other health inequities, such as in the care of patients with multiple myeloma.

“There’s some evidence that Black patients are not using even the agents we have as [are] some of the other groups, so there may be some distributional inequities there as well,” she said.

The study was funded by ASH and the Yale School of Medicine. Dr. Goshua, Dr. Oluwole, and Dr. Lee have disclosed no relevant financial relationships.

NASHVILLE, TENN. – About 21% of teens newly diagnosed with epilepsy experience suicidal ideation, and the percentage jumps to 31% within 3 years, new research reveals.

“We hope these results inspire epileptologists and neurologists to both recognize and screen for suicide ideation and behaviors in their adolescent patients,” said study investigator Hadley Greenwood, a third-year medical student at New York University.

The new data should also encourage providers “to become more comfortable” providing support to patients, “be that by increasing their familiarity with prescribing different antidepressants or by being well versed in how to connect patients to resources within their community,” said Mr. Greenwood.

The findings were presented here at the annual meeting of the American Epilepsy Society.
 

Little research

Previous studies have reported on the prevalence of suicidality as well as depression and anxiety among adults with epilepsy. “We wanted to look at adolescents because there’s much less in the literature out there about psychiatric comorbidity, and specifically suicidality, in this population,” said Mr. Greenwood.

Researchers used data from the Human Epilepsy Project, a study that collected data from 34 sites in the United States, Canada, Europe, and Australia from 2012 to 2017.

From a cohort of more than 400 participants, researchers identified 67 patients aged 11-17 years who were enrolled within 4 months of starting treatment for focal epilepsy.

Participants completed the Columbia–Suicide Severity Rating Scale (C-SSRS) at enrollment and at follow-ups over 36 months. The C-SSRS measures suicidal ideation and severity, said Mr. Greenwood.

“It’s scaled from passive suicide ideation, such as thoughts of ‘I wish I were dead’ without active intent, all the way up to active suicidal ideation with a plan and intent.”

Researchers were able to distinguish individuals with passive suicide ideation from those with more serious intentions, said Mr. Greenwood. They used medical records to evaluate the prevalence of suicidal ideation and behavior.

The investigators found that more than one in five (20.9%) teens endorsed any lifetime suicide ideation. This, said Mr. Greenwood, is “roughly equivalent” to the prevalence reported earlier in the adult cohort of the Human Epilepsy Project (21.6%).
 

‘Striking’ rate

The fact that one in five adolescents had any lifetime suicide ideation is “definitely a striking number,” said Mr. Greenwood.

Researchers found that 15% of patients experienced active suicide ideation, 7.5% exhibited preparatory or suicidal behaviors, and 3% had made a prior suicide attempt.

All of these percentages increased at 3 years: Thirty-one percent for suicide ideation; 25% for active suicide behavior, 15% for preparatory or suicide behaviors, and 5% for prior suicide attempt.

The fact that nearly one in three adolescents endorsed suicide ideation at 3 years is another “striking” finding, said Mr. Greenwood.

Of the 53 adolescents who had never had suicide ideation at the time of enrollment, 7 endorsed new-onset suicide ideation in the follow-up period. Five of 14 who had had suicide ideation at some point prior to enrollment continued to endorse it.

“The value of the study is identifying the prevalence and identifying the significant number of adolescents with epilepsy who are endorsing either suicide ideation or suicidal behaviors,” said Mr. Greenwood.

The researchers found that among younger teens (aged 11–14 years) rates of suicide ideation were higher than among their older counterparts (aged 15–17 years).

The study does not shed light on the biological connection between epilepsy and suicidality, but Mr. Greenwood noted that prior research has suggested a bidirectional relationship.

“Depression and other psychiatric comorbidities might exist prior to epileptic activity and actually predispose to epileptic activity.”

Mr. Greenwood noted that suicide ideation has “spiked” recently across the general population, and so it’s difficult to compare the prevalence in her study with “today’s prevalence.”

However, other research generally shows that the suicide ideation rate in the general adolescent population is much lower than in teens with epilepsy.

Unique aspects of the current study are that it reports suicide ideation and behaviors at around the time of an epilepsy diagnosis and documents how suicidality progresses or resolves over time, said Mr. Greenwood.
 

Underdiagnosed, undertreated

Commenting on the research, Elizabeth Donner, MD, director of the comprehensive epilepsy program, Hospital for Sick Children, and associate professor, department of pediatrics, University of Toronto, said a “key point” from the study is that the suicidality rate among teens with epilepsy exceeds that of children not living with epilepsy.

“We are significantly underdiagnosing and undertreating the mental health comorbidities in epilepsy,” said Dr. Donner. “Epilepsy is a brain disease and so are mental health disorders, so it shouldn’t come as any surprise that they coexist in individuals with epilepsy.”

The new results contribute to what is already known about the significant mortality rates among persons with epilepsy, said Dr. Donner. She referred to a 2018 study that showed that people with epilepsy were 3.5 times more likely to die by suicide.

Other research has shown that people with epilepsy are 10 times more likely to die by drowning, mostly in the bathtub, said Dr. Donner.

“You would think that we’re educating these people about risks related to their epilepsy, but either the messages don’t get through, or they don’t know how to keep themselves safe,” she said.

“This needs to be seen in a bigger picture, and the bigger picture is we need to recognize comorbid mental health issues; we need to address them once recognized; and then we need to counsel and support people to live safely with their epilepsy.

The study received funding from the Epilepsy Study Consortium, Finding a Cure for Epilepsy and Seizures (FACES) and other related foundations, UCB, Pfizer, Eisai, Lundbeck, and Sunovion. Mr. Greenwood and Dr. Donner report no relevant financial relationships.
