SAN ANTONIO – A proprietary oral fixed-dose, triple-antibiotic combination pill offers a promising new approach to the treatment of Crohn’s disease, David Y. Graham, MD, declared at the annual meeting of the American College of Gastroenterology.

In the phase 3 MAP US trial, patients with Crohn’s disease who were randomized to the fixed-dose combination of 45 mg rifabutin, 95 mg clarithromycin, and 10 mg clofazimine, known for now as RHB-104, experienced significantly higher rates of clinical remission and improvement in inflammation as assessed endoscopically and via biomarkers, compared with placebo-treated controls, reported Dr. Graham, professor of medicine at Baylor College of Medicine, Houston.

RHB-104 is effective against Mycobacterium avium paratuberculosis (MAP) – and therein hangs a tale.

“MAP has been considered as a possible cause of Crohn’s disease since the disease was described by Crohn in 1932,” the gastroenterologist noted. “These randomized trial data provide further evidence suggesting an important role for MAP or similar microorganisms in the pathogenesis of Crohn’s disease.”

For Dr. Graham, this is a case of deja vu all over again. More than a quarter century ago he was lead author of a highly influential randomized, controlled trial which established that treatment with antibiotics directed against Helicobacter pylori cured peptic ulcer disease. As such, he became internationally recognized as a key figure in the resultant revolution in peptic ulcer treatment. He hears an echo of that earlier transformative change in the MAP US results.

“This is either an additional therapy or it’s the beginning of a paradigm shift. I mean, I see this as we’re standing at the same place now as we were standing with Helicobacter pylori 30 years ago, when the question was: Have we found something that we can eradicate and change the natural history of the disease and cure it? You can say this [MAP-directed therapy] is going in that direction, but it certainly hasn’t gotten to the point of proof yet. The results have to be reproduced,” he said.

The MAP US trial included 331 patients with moderate to severely active Crohn’s disease at 92 sites who had failed to achieve an adequate response with conventional therapies. Participants were randomized double blind to twice-daily RHB-104 or placebo for 52 weeks. Those not in remission at 26 weeks could opt for open-label RHB-104. Background concomitant treatment with corticosteroids, tumor necrosis factor inhibitors, and immunosuppressives was permitted.

The primary outcome was clinical remission as defined by a Crohn’s Disease Activity Index (CDAI) score below 150 at week 26. This was achieved in 36.7% of the active treatment group and 23% of controls, a highly significant difference. The clinical remission rates at week 16 were 42.2% and 29.1%, respectively. At week 26, 44% of RHB-104-treated patients had achieved at least a 100-point reduction in CDAI score, compared with baseline, as did 30.9% of controls. The key symptom score provided by the sum of the abdominal pain and bowel movement components of the CDAI was significantly lower in the RHB-104 group than in controls from week 16 on.

The remission rate at week 26 in the group on RHB-104 was similarly favorable regardless of whether or not they were on anti–tumor necrosis factor therapy.

“This suggests that RHB-104 can be used effectively and safely as an adjunct treatment to other medications to enhance the response to medical therapy,” according to Dr. Graham, who was principal investigator for MAP US.

The composite endpoint of clinical remission plus at least a 50% reduction from baseline in fecal calprotectin or C-reactive protein was achieved in 21.1% of the RHB-104 group and 9.1% of controls at week 26, and by 16.9% on RHB-104 and 7.9% on placebo at week 52.

In the 35 patients who underwent endoscopy at week 26, a 50% or greater reduction in the Simple Endoscopic Score in Crohn’s Disease was documented in 28.6% of patients on RHB-104 versus 4.8% of controls.

Durable remission, defined as a CDAI score below 150 at all study visits from week 16 to week 52, was achieved in 18.7% of the RHB-104 group, compared with 8.5% of controls.

The side effect profiles of RHB-104 and placebo were similar, with no serious adverse events recorded in the 52-week study. An increase in the QT interval on ECG was noted in the RHB-104 group from week 4 on, but it wasn’t associated with any clinical findings. Further study of this ECG finding is underway.

Several audience members rose to urge caution in interpreting the MAP US data.

“We must adhere to Koch’s postulates before we make conclusions about causative agents of an infectious disease, and I didn’t see those data here. So I look forward to a future presentation that shares that,” one gastroenterologist commented.

“I haven’t seen any data here that shows Mycobacterium was present in these patients,” noted another.

Dr. Graham replied that MAP US was a hypothesis-driven clinical trial: Crohn’s disease has much in common with an inflammatory bowel disease occurring in ruminant animals, where RHB-104 has shown treatment efficacy.

“This is a Mycobacterium avium organism, so it’s not something you’re going to cure in 2 weeks or 2 months. But the question is, do you have an effect on the disease, and the answer in MAP US was unquestionably yes. It’s very positive data to further pursue the hypothesis, but the study doesn’t provide a definitive answer,” he said.

Dr. Graham reported serving as a consultant to RedHill Biopharma, the study sponsor.

ORLANDO – There is an urgent need for new therapies to treat relapsed or refractory peripheral T-cell lymphoma, but results of a phase 2 study suggest that monotherapy with the immune checkpoint inhibitor nivolumab (Opdivo) is not the hoped-for salvage treatment.

Neil Osterweil/MDedge News

An interim analysis of data on 12 patients with peripheral T-cell lymphoma (PTCL) treated with nivolumab monotherapy showed an overall response rate of 33%, consisting of 2 complete responses and 2 partial responses. But the responses were short lived, and one patient had hyperprogressive disease – dramatic progression within one cycle of treatment – while two more had progression within two cycles, leading to a trial halt, reported N. Nora Bennani, MD, from the Mayo Clinic in Rochester, Minn.

“These findings likely reflect the distinct biology of PTCL and should be considered when designing future studies using checkpoint inhibitors in these diseases,” she said at the annual meeting of the American Society of Hematology.

The rationale for using an immune checkpoint inhibitor directed against the programmed death–1 protein and its ligands (PD and PD-L1/2) is that malignant cells in PTCL induce a profoundly immunosuppressive tumor microenvironment. Checkpoint inhibitors have shown strong activity against relapsed Hodgkin lymphoma, and the Mayo Clinic researchers speculated that an anti-PD-1 agent could have a similar effect in PTCL.

They had originally planned to enroll 29 patients into a phase 2 trial with nivolumab delivered 240 mg every 2 weeks for eight cycles, followed by a dose of 480 mg given every 4 weeks until disease progression or intolerable toxicities.

Patients were eligible if they had biopsy-confirmed relapsed or refractory PTCL, measurable disease on cross-sectional imaging of at least 1.5 cm, and prior systemic chemoimmunotherapy and/or autologous stem cell transplantation.

The interim analysis included 12 patients who received at least one dose of nivolumab. Of the 12 patients, 6 had angioimmunoblastic T-cell lymphoma (AITL), 3 had PTCL not otherwise specified, and 1 each had ALK-negative anaplastic large cell lymphoma (ALK-ALCL), enteropathy-associated T-cell lymphoma (EATL), or hepatosplenic gamma/delta T-cell lymphoma.

All patients had Ann Arbor stage III/IV disease, and 11 had extranodal involvement.

As noted, there were 4 responses among the 12 patients, consisting of 1 complete response in the patient with ALK-ALCL and 1 in a patient with AITL, and 2 partial responses – 1 in a patient with PTCL-NOS, and 1 in the patient with EATL.

The median progression-free survival for all 12 patients was short at 2.7 months, and the median overall survival was estimated at 6.7 months.

“It was staggering to see this: The duration of response was significantly short, less than 2 months,” Dr. Bennani said.

Nonhematologic toxicities were seen in 5 of the 12 patients (42%), and hematologic adverse events occurred in 3 (25%). All patients are now off treatment, 10 because of disease progression, 1 because of acute pancreatitis, and the aforementioned patient with hyperprogressive disease.

The patient with hyperprogressive disease had significant progression in tonsillar and cervical lymphadenopathy within 7-10 days of nivolumab infusion, with biopsy-proven AITL in the involved nodes.

“I believe that, in this patient population, combination therapies will be key. I think checkpoint blockers alone are not going to be sufficient to see meaningful outcomes in these patients,” Dr. Bennani said in an interview.

“An overall response rate of 33% is significant, because most other agents that were FDA approved in this patient population have response rates around 30%,” she said, adding that it’s possible that the patients with rapid progression had disease too advanced to be effectively treated with a checkpoint inhibitor.

“Ideally however, if we want to move forward, it will need to be with combinations of checkpoint inhibitors with HDAC [histone deacetylase] inhibitors, hypomethylating agents, or even PI3 kinase inhibitors,” she said.

­The study was supported by Bristol-Myers Squibb. Dr. Bennani reported research funding and advisory board activities for Bristol-Myers Squibb and others.

ORLANDO – Combining aspirin and direct oral anticoagulant (DOAC) therapy for the secondary prevention of venous thromboembolism (VTE) or the prevention of stroke associated with nonvalvular atrial fibrillation (NVAF) without a clear indication was associated with increased bleeding risks in a large registry-based cohort.

Sharon Worcester/MDedge News

The study, which involved a cohort of 2,045 patients who were followed at 6 anticoagulation clinics in Michigan during January 2009–June 2019, also found no apparent improvement in thrombosis incidence with the addition of aspirin, Jordan K. Schaefer, MD, reported during a press briefing at the annual meeting of the American Society of Hematology.

Of the cohort patients, 639 adults who received a DOAC plus aspirin after VTE or for NVAF without a clear indication were compared with 639 propensity-matched controls. The bleeding event rate per 100 patient years was 39.50 vs. 32.32 at an average of 15.2 months of follow-up in the combination therapy and DOAC monotherapy groups, respectively, said Dr. Schaefer of the division of hematology/oncology, department of internal medicine, University of Michigan, Ann Arbor.

“This result was statistically significant for clinically relevant non-major bleeding, with an 18.7 rate per 100 patient years, compared with 13.5 for DOAC monotherapy,” (P = .02), he said. “We also saw a significant increase in non-major bleeding with combination therapy, compared with direct oral anticoagulant monotherapy” (rate, 32.82 vs. 25.88; P =.04).

No significant difference was seen overall (P =.07) or for other specific types of bleeding, he noted.

The observed rates of thrombosis in the groups, respectively, were 2.35 and 2.23 per 100 patient years (P =.95), he said, noting that patients on combination therapy also had more emergency department visits and hospitalizations, but those differences were not statistically significant.

“Direct-acting oral anticoagulants, which include apixaban, dabigatran, edoxaban, and rivaroxaban, are increasingly used in clinical practice for indications that include the prevention of strokes for patients with nonvalvular atrial fibrillation, and the treatment and secondary prevention of venous thromboembolic disease,” Dr. Schaefer said.

Aspirin is commonly used in clinical practice for various indications, including primary prevention of heart attacks, strokes, and colorectal cancer, as well as for thromboprophylaxis in patients with certain blood disorders or with certain cardiac devices, he added.

“Aspirin is used for the secondary prevention of thrombosis for patients with known coronary artery disease, peripheral artery disease, or carotid artery disease,” he said. “And while adding aspirin to a DOAC is often appropriate after acute coronary syndromes or percutaneous coronary intervention, many patients receive the combination therapy without a clear indication, he said, noting that increasing evidence in recent years, largely from patients treated with warfarin and aspirin, suggest that the approach may do more harm than good for certain patients.

Specifically, there’s a question of whether aspirin is increasing the rates of bleeding without protecting patients from adverse thrombotic outcomes.

“This has specifically been a concern for patients who are on full-dose anticoagulation,” he said.

In the current study, patient demographics, comorbidities, and concurrent medications were well balanced in the treatment and control groups after propensity score matching, he said, noting that patients with a history of heart valve replacement, recent MI, or less than 3 months of follow-up were excluded.

“These findings need to be confirmed in larger studies, but until such data [are] available, clinicians and patients should continue to balance the relative risks and benefits of adding aspirin to their direct oral anticoagulant therapy,” Dr. Schaefer said. “Further research needs to evaluate key subgroups to see if any particular population may benefit from combination therapy compared to DOAC therapy alone.”

Dr. Schaefer reported having no disclosures.

The study, which involved a cohort of 2,045 patients who were followed at 6 anticoagulation clinics in Michigan during January 2009–June 2019, also found no apparent improvement in thrombosis incidence with the addition of aspirin, Jordan K. Schaefer, MD, reported during a press briefing at the annual meeting of the American Society of Hematology.

Of the cohort patients, 639 adults who received a DOAC plus aspirin after VTE or for NVAF without a clear indication were compared with 639 propensity-matched controls. The bleeding event rate per 100 patient years was 39.50 vs. 32.32 at an average of 15.2 months of follow-up in the combination therapy and DOAC monotherapy groups, respectively, said Dr. Schaefer of the division of hematology/oncology, department of internal medicine, University of Michigan, Ann Arbor.

“This result was statistically significant for clinically relevant non-major bleeding, with an 18.7 rate per 100 patient years, compared with 13.5 for DOAC monotherapy,” (P = .02), he said. “We also saw a significant increase in non-major bleeding with combination therapy, compared with direct oral anticoagulant monotherapy” (rate, 32.82 vs. 25.88; P =.04).

No significant difference was seen overall (P =.07) or for other specific types of bleeding, he noted.

The observed rates of thrombosis in the groups, respectively, were 2.35 and 2.23 per 100 patient years (P =.95), he said, noting that patients on combination therapy also had more emergency department visits and hospitalizations, but those differences were not statistically significant.

“Direct-acting oral anticoagulants, which include apixaban, dabigatran, edoxaban, and rivaroxaban, are increasingly used in clinical practice for indications that include the prevention of strokes for patients with nonvalvular atrial fibrillation, and the treatment and secondary prevention of venous thromboembolic disease,” Dr. Schaefer said.

Aspirin is commonly used in clinical practice for various indications, including primary prevention of heart attacks, strokes, and colorectal cancer, as well as for thromboprophylaxis in patients with certain blood disorders or with certain cardiac devices, he added.

“Aspirin is used for the secondary prevention of thrombosis for patients with known coronary artery disease, peripheral artery disease, or carotid artery disease,” he said. “And while adding aspirin to a DOAC is often appropriate after acute coronary syndromes or percutaneous coronary intervention, many patients receive the combination therapy without a clear indication, he said, noting that increasing evidence in recent years, largely from patients treated with warfarin and aspirin, suggest that the approach may do more harm than good for certain patients.

Specifically, there’s a question of whether aspirin is increasing the rates of bleeding without protecting patients from adverse thrombotic outcomes.

“This has specifically been a concern for patients who are on full-dose anticoagulation,” he said.

In the current study, patient demographics, comorbidities, and concurrent medications were well balanced in the treatment and control groups after propensity score matching, he said, noting that patients with a history of heart valve replacement, recent MI, or less than 3 months of follow-up were excluded.

“These findings need to be confirmed in larger studies, but until such data [are] available, clinicians and patients should continue to balance the relative risks and benefits of adding aspirin to their direct oral anticoagulant therapy,” Dr. Schaefer said. “Further research needs to evaluate key subgroups to see if any particular population may benefit from combination therapy compared to DOAC therapy alone.”

Dr. Schaefer reported having no disclosures.

ORLANDO – A dual-targeted chimeric antigen receptor (CAR) T-cell therapy has demonstrated a high overall response rate, a long response duration, and manageable safety in patients with relapsed or refractory multiple myeloma, according to an investigator in a phase 1 study.

Benjamin Pena/Medscape

The overall response rate exceeded 90%, and about three-quarters of patients remained progression-free at 9 months after treatment with the CAR T-cell therapy, which targets both B-cell maturation antigen (BCMA) and CD38, the study investigator reported.

Grade 3 or greater cytokine release syndrome (CRS) occurred in about one-quarter of the patients, and no neurotoxicity was observed, according to investigator Yu Hu, MD, of Tongji Medical College in Hubei, China.

“These initial data provide strong evidence to support the further development of a dual-targeted CAR T-cell therapy for hard to treat multiple myeloma,” Dr. Hu said in a press conference.

Short-term relapse has been a “major challenge” with current CAR T-cell therapies currently under investigation for myeloma, most of which target BCMA, according to Dr. Hu.

He said the bispecific CAR T-cell therapy under investigation, known as BM38, was designed to target antigen loss and increase persistence of effector cells. According to the investigator, this was the first study to focus on an anti-BCMA and CD38 dual-targeted CAR T-cell therapy for patients with relapsed or refractory multiple myeloma.

Gary J. Schiller, MD, of UCLA Health, who moderated the press conference, said that while dual-targeting is a potentially “attractive” approach in these hard-to-treat patients, further follow-up is needed to see duration of response and to see if antigen escape re-emerges.

“Cellular therapy is costly, in terms of toxicity as well as financial costs, so you would like to see what the durability of responses is before engaging in that as a late-stage therapy, not to mention moving it up front,” Dr. Schiller said in an interview.

The median progression-free survival (PFS) duration had not been reached at the time of this report, though the 9-month PFS rate was 78.87%, according to the data presented by Dr. Hu.

ORLANDO – A novel chimeric antigen receptor T (CAR T) cell construct is associated with deep clinical responses in patients with multiple myeloma for whom prior lines of therapy – some numbering in the double digits – have failed.

Among 29 patients with multiple myeloma enrolled in a phase 1b/2 trial of JNJ-4528, the overall response rate (ORR) at 6 months median follow-up was 100%, including 69% complete responses, with 27 patients remaining free of disease progression at a median of 6 months, reported Deepu Madduri, MD, of Icahn School of Medicine at Mount Sinai, New York.

Benjamin Pena/Medscape

“These are very heavily pretreated patients, and so getting early and deep responses is quite amazing,” she said at a briefing prior to presentation of the data at the annual meeting of the American Society of Hematology.

JNJ-4528 is a second-generation CAR T containing two single-domain antibodies targeted against B-cell maturation protein (BCMA). As previously reported, an identical CAR T cell construct showed a high overall response with manageable toxicities in 74 patients with relapsed/refractory multiple myeloma. JNJ-4528 was granted a breakthrough therapy designation for relapsed/refractory multiple myeloma by the Food and Drug Administration on Dec. 6, 2019, and a priority medicines (PRIME) designation by the European Medicines Agency in April 2019.

BCMA was first described in myeloma in 2004 as a mechanism for the growth and survival of malignant plasma cells. Several research groups are currently investigating CAR T cells or monoclonal antibodies targeted to BCMA. The product closest to receiving FDA approval is likely BB2121.

Patient-reported outcomes support pembrolizumab plus chemotherapy for first-line treatment of metastatic non–small cell lung cancer (NSCLC), based on results from the KEYNOTE-407 trial.

At week 18, patients given pembrolizumab more often reported clinically meaningful health-related quality of life improvements than those in the placebo group, according to lead author Julien Mazieres, MD, PhD, of Paul Sabatier University in Toulouse, France, and colleagues.

Writing in the Journal of Clinical Oncology, the investigators explained that these findings build upon previously published results from KEYNOTE-407, which showed that adding pembrolizumab to chemotherapy in the first line could extend both progression-free and overall survival among patients with NSCLC. The benefits to quality of life associated with pembrolizumab align with similar findings from the KEYNOTE-024 and KEYNOTE-189 trials, they added.

The present analysis involved 559 patients with treatment-naive metastatic NSCLC. Patients were randomized to receive 4 cycles of placebo or pembrolizumab once every 3 weeks with carboplatin-based chemotherapy, followed by pembrolizumab or placebo for an additional 31 cycles. Health-related quality of life was assessed by two measures: the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire–Core 30 (QLQ-C30) and QLQ–Lung Cancer Module 13 (QLQ-LC13).

Of the 559 patients enrolled, 554 completed at least one QLQ-C30 assessment and 553 completed at least one QLQ-LC13 assessment. These quality of life scores were compared temporally within treatment groups, from baseline to week 9 and week 18, and between groups. The investigators also analyzed median time to deterioration in chest pain, cough, and dyspnea.

Results showed that patients in the pembrolizumab group had statistically significant improvements in patient-reported outcomes over time and more frequently reported improvements than patients in the placebo group. Specifically, in the pembrolizumab group, least-squares mean score improved from baseline to week 9 (1.8) and week 18 (4.3); in comparison, least-squares mean score deteriorated in the placebo group from baseline to week 9 (–1.8) and week 18 (–0.57). Compared with placebo, treatment with pembrolizumab was associated with a least-squares mean change of 3.6 at week 9 (nominal P = .0337) and 4.9 at week 18 (nominal P = .0060). Stated differently, at week 18, compared with placebo, more patients in the pembrolizumab group reported clinically meaningful improvements in health-related quality of life (36.2% vs. 27.7%), and relatively fewer reported deterioration (22.8% vs. 31.3%). Median time to deterioration in symptoms was not reached in either treatment arm.

“These health-related quality of life findings, along with the improved efficacy (including overall survival benefit) of pembrolizumab plus carboplatin and paclitaxel/nab-paclitaxel, support its use as a first-line treatment of metastatic squamous NSCLC, regardless of programmed death–ligand 1 expression,” the investigators concluded.

The study was funded by Merck. The investigators reported additional relationships with Novartis, Genentech, Pfizer, and others.

SAN DIEGO – Intensive blood pressure control over 4 years reduced the overall risk of all-cause dementia by 17%, compared with standard care, but in subanalyses of the Systolic Blood Pressure Intervention Trial (SPRINT) it was also associated with significant decreases in cognitive function and total brain volume, researchers said at the Clinical Trials on Alzheimer’s Disease conference.

Michele G. Sullivan/MDedge News

Whether these between-group differences were clinically meaningful was the topic of some debate, but they were enough to prompt Mary Sano, PhD, to strongly state her reservations.

“The cardiovascular effects of SPRINT were impressive, but I am concerned about minimizing the potentially negative effect on cognition,” said Dr. Sano, professor of psychiatry and director of the Alzheimer’s Disease Research Center at the Icahn School of Medicine at Mount Sinai, New York. “Do I really want to treat a healthy, nonimpaired patient like this if I have to warn them that their cognition might actually get worse? We just cannot minimize this risk. There is very strong evidence that [intensive treatment of blood pressure] might be a step backward in cognition. Would you lower your own blood pressure at a risk of losing some points on your cognition?”

The subanalyses were conducted as part of the SPRINT Memory and Cognition In Decreased Hypertension (SPRINT MIND) substudy, which looked at cardiovascular and mortality outcomes in 9,361 subjects whose hypertension was managed intensively or by standard care (target systolic blood pressure less than 120 mm Hg vs. less than 140 mm Hg). The trial was stopped early because of a 25% reduction in the primary composite cardiovascular disease endpoint and a 27% reduction in all-cause mortality in the intensive-treatment group.

SPRINT MIND examined the risks of incident probable dementia, mild cognitive impairment (MCI), and a composite outcome of both. Intensive control reduced the risk of MCI by 19% and the combined outcome by 15%.

At the conference, SPRINT MIND investigators presented three long-term subanalyses with a median intervention and follow-up time of about 4 years.

Sarah Gaussoin of Wake Forest University, Winston-Salem, N.C., presented unpublished data detailing the effects of intensive control on several dementia subtypes: nonamnestic single domain, nonamnestic multidomain, amnestic single domain, and amnestic multidomain. There were 640 subjects in this analysis.

After a median of 3.3 years of intervention and 5 years of follow-up, there were no differences in the rate of incident probable dementia between the single- and multidomain nonamnestic groups. “We did see a strong 22% decreased risk in single-domain versus multidomain amnestic MCI, however,” she said.

Nicholas Pajewski, PhD, also of Wake Forest University, discussed more detailed cognitive outcomes in SPRINT MIND among 2,900 subjects who had a full battery of cognitive testing at every assessment over 5 years. The outcomes included memory deficit and processing speed.

Dr. Pajewski reported finding no significant difference between the groups in the rates of memory decline in either outcome. But there was a greater rate of decline in processing speed in the intensively treated group, he added. The difference was small but statistically significant.

The difference was largely driven by results of a single cognitive test – the Trail Making Test Part A. “It corresponded to about a 1.25-second increase over 4 years,” in processing speed on this test, Dr. Pajewski said.

There were no between-group differences in any of the other domains explored, including language, executive function, global cognitive function, or the Montreal Cognitive Assessment.

“Obviously, these results are perplexing,” given the overall positive results of SPRINT MIND, he said. “Intensive blood pressure control is a beneficial thing, and we expected to see an effect on memory, or a blunting of decline, and instead we saw some small decrements going the other way. This led us to speculate about what’s going on.”

The trial relied on a narrow definition of MCI that might have affected the outcomes. There was also a very broad range of ages in the study, ranging from 53 to 86 years. More importantly, he said, the original SPRINT study didn’t collect cognitive data at baseline, so there was no way to know how many subjects already might have had MCI when they entered the trial.

Ilya Nasrallah, MD, PhD, of the University of Pennsylvania, Philadelphia, presented MRI data on white-matter lesions, hippocampal volume fractional anisotropy in the cingulum, and cerebral blood flow. The median time between scans was 4 years, with a median treatment time of 3.4 years.

The standard-care group showed a significantly greater increase in white-matter lesion volume at the follow-up scan than did the intensive-treatment group (1.45 cm³ vs. 0.92 cm³). But the intensively treated group had significantly more brain atrophy, losing a median of 30.6 cm^3, compared with a loss of 26.9 cm³ in the standard-treatment group.

“It was a very small difference amounting to less than 1% of the total brain volume, but it was still statistically significant,” Dr. Nasrallah said.

Loss of gray-matter volume drove about two-thirds of the difference in the intensively treated group. There was a corresponding increase in cerebrospinal fluid volume that was driven by differences in the ventricles and the subarachnoid space.

However, there were no significant differences in right, left, or total hippocampal volume. There also were no differences in cingulate bundle anisotropy or cerebral blood flow.

SPRINT was funded by the National Institutes of Health. None of the investigators reported having financial conflicts of interest.

SAN DIEGO – Intensive blood pressure control over 4 years reduced the overall risk of all-cause dementia by 17%, compared with standard care, but in subanalyses of the Systolic Blood Pressure Intervention Trial (SPRINT) it was also associated with significant decreases in cognitive function and total brain volume, researchers said at the Clinical Trials on Alzheimer’s Disease conference.

Whether these between-group differences were clinically meaningful was the topic of some debate, but they were enough to prompt Mary Sano, PhD, to strongly state her reservations.

“The cardiovascular effects of SPRINT were impressive, but I am concerned about minimizing the potentially negative effect on cognition,” said Dr. Sano, professor of psychiatry and director of the Alzheimer’s Disease Research Center at the Icahn School of Medicine at Mount Sinai, New York. “Do I really want to treat a healthy, nonimpaired patient like this if I have to warn them that their cognition might actually get worse? We just cannot minimize this risk. There is very strong evidence that [intensive treatment of blood pressure] might be a step backward in cognition. Would you lower your own blood pressure at a risk of losing some points on your cognition?”

The subanalyses were conducted as part of the SPRINT Memory and Cognition In Decreased Hypertension (SPRINT MIND) substudy, which looked at cardiovascular and mortality outcomes in 9,361 subjects whose hypertension was managed intensively or by standard care (target systolic blood pressure less than 120 mm Hg vs. less than 140 mm Hg). The trial was stopped early because of a 25% reduction in the primary composite cardiovascular disease endpoint and a 27% reduction in all-cause mortality in the intensive-treatment group.

SPRINT MIND examined the risks of incident probable dementia, mild cognitive impairment (MCI), and a composite outcome of both. Intensive control reduced the risk of MCI by 19% and the combined outcome by 15%.

At the conference, SPRINT MIND investigators presented three long-term subanalyses with a median intervention and follow-up time of about 4 years.

Sarah Gaussoin of Wake Forest University, Winston-Salem, N.C., presented unpublished data detailing the effects of intensive control on several dementia subtypes: nonamnestic single domain, nonamnestic multidomain, amnestic single domain, and amnestic multidomain. There were 640 subjects in this analysis.

After a median of 3.3 years of intervention and 5 years of follow-up, there were no differences in the rate of incident probable dementia between the single- and multidomain nonamnestic groups. “We did see a strong 22% decreased risk in single-domain versus multidomain amnestic MCI, however,” she said.

Nicholas Pajewski, PhD, also of Wake Forest University, discussed more detailed cognitive outcomes in SPRINT MIND among 2,900 subjects who had a full battery of cognitive testing at every assessment over 5 years. The outcomes included memory deficit and processing speed.

Dr. Pajewski reported finding no significant difference between the groups in the rates of memory decline in either outcome. But there was a greater rate of decline in processing speed in the intensively treated group, he added. The difference was small but statistically significant.

The difference was largely driven by results of a single cognitive test – the Trail Making Test Part A. “It corresponded to about a 1.25-second increase over 4 years,” in processing speed on this test, Dr. Pajewski said.

There were no between-group differences in any of the other domains explored, including language, executive function, global cognitive function, or the Montreal Cognitive Assessment.

“Obviously, these results are perplexing,” given the overall positive results of SPRINT MIND, he said. “Intensive blood pressure control is a beneficial thing, and we expected to see an effect on memory, or a blunting of decline, and instead we saw some small decrements going the other way. This led us to speculate about what’s going on.”

The trial relied on a narrow definition of MCI that might have affected the outcomes. There was also a very broad range of ages in the study, ranging from 53 to 86 years. More importantly, he said, the original SPRINT study didn’t collect cognitive data at baseline, so there was no way to know how many subjects already might have had MCI when they entered the trial.

Women are more likely to experience acute toxic effects from chemoradiotherapy for rectal cancer than men, but this does not appear to negatively impact treatment adherence or outcomes, research suggests.

In a research letter published in JAMA Oncology, Markus Diefenhardt, MD, from the University of Frankfurt and coauthors wrote that, while the risk of toxic chemotherapy effects was known to be greater in women for a number of cancers, this association was relatively unexplored for rectal cancer.

The researchers performed a pooled analysis of data from two phase 3, randomized clinical trials, involving 1,016 patients with rectal cancer – 28.6% of whom were female – treated with fluorouracil-based chemoradiotherapy followed by surgery and adjuvant fluorouracil.

They found that women experienced significantly higher rates of leukopenia and diarrhea than men. Grade 3-4 leukopenia was experienced by 28.6% of women, compared with 20.5% of men, and grades 3-4 diarrhea was experienced by 17.2% of women, compared with 8.1% of men.

Despite this, the study found similar rates of adherence to treatment between men and women both for neoadjuvant and adjuvant chemoradiotherapy. Women also had similar rates of disease-free survival and overall survival as men, and there were no significant differences in local recurrence or distant metastases.

“Although to our knowledge no data support using different chemotherapy regimens for men and women with rectal cancer, increased awareness of a higher risk of toxic effects among women may facilitate refinement of fluorouracil-based chemoradiotherapy and adjuvant chemotherapy, such as tailored patient education, closer monitoring of adverse effects, and earlier introduction of supportive measures,” the authors wrote.

The authors proposed several possible explanations for the higher rate of toxic effects in women. For example, women may have lower levels of the enzyme dihydropyridine dehydrogenase, which catabolizes fluorouracil, which could result in overdosing of fluorouracil. Similarly, sex-specific body fat composition could also contribute to fluorouracil overdosing in women.

The study also saw fewer postoperative complications in women, which the authors suggested could be related to the lower rate of abdominoperineal resections in women.

The two clinical trials included in the study were funded by German Cancer Aid. One author declared funding from German Cancer Aid, another declared a range of honoraria, research fees and institutional funding from the pharmaceutical sector. No other conflicts of interest were declared.

High reliability organizations (HROs) incorporate continuous process improvement through leadership commitment to create a safety culture that works toward creating a zero-harm environment.¹ The Veterans Health Administration (VHA) has set transformational goals for becoming an HRO. In this article, we describe VIONE, an expanding medication deprescribing clinical program, which exemplifies the translation of HRO principles into health care system models. Both VIONE and HRO are globally relevant.

Reducing medication errors and related adverse drug events are important for achieving zero harm. Preventable medical errors rank behind heart disease and cancer as the third leading cause of death in the US.² The simultaneous use of multiple medications can lead to dangerous drug interactions, adverse outcomes, and challenges with adherence. When a person is taking multiple medicines, known as polypharmacy, it is more likely that some are potentially inappropriate medications (PIM). Current literature highlights the prevalence and dangers of polypharmacy, which ranks among the top 10 common causes of death in the US, as well as suggestions to address preventable adverse outcomes from polypharmacy and PIM.^3-5

Deprescribing of PIM frequently results in better disease management with improved health outcomes and quality of life.⁴ Many health care settings lack standardized approaches or set expectations to proactively deprescribe PIM. There has been insufficient emphasis on how to make decisions for deprescribing medications when therapeutic benefits are not clear and/or when the adverse effects may outweigh the therapeutic benefits.⁵

It is imperative to provide practice guidance for deprescribing nonessential medications along with systems-based infrastructure to enable integrated and effective assessments during opportune moments in the health care continuum. Multimodal approaches that include education, risk stratification, population health management interventions, research and resource allocation can help transform organizational culture in health care facilities toward HRO models of care, aiming at zero harm to patients.

The practical lessons learned from VIONE implementation science experiences on various scales and under diverse circumstances, cumulative wisdom from hindsight, foresight and critical insights gathered during nationwide spread of VIONE over the past 3 years continues to propel us toward the desirable direction and core concepts of an HRO.

The VIONE program facilitates practical, real-time interventions that could be tailored to various health care settings, organizational needs, and available resources. VIONE implements an electronic Computerized Patient Record System (CPRS) tool to enable planned cessation of nonessential medications that are potentially harmful, inappropriate, not indicated, or not necessary. The VIONE tool supports systematic, individualized assessment and adjustment through 5 filters (Figure 1). It prompts providers to assign 1 of these filters intuitively and objectively. VIONE combines clinical evidence for best practices, an interprofessional team approach, patient engagement, adapted use of existing medical records systems, and HRO principles for effective implementation.

As a tool to support safer prescribing practices, VIONE aligns closely with HRO principles (Table 1) and core pillars (Table 2).^6-8 A zero-harm safety culture necessitates that medications be used for correct reasons, over a correct duration of time, and following a correct schedule while monitoring for adverse outcomes. However, reality generally falls significantly short of this for a myriad of reasons, such as compromised health literacy, functional limitations, affordability, communication gaps, patients seen by multiple providers, and an accumulation of prescriptions due to comorbidities, symptom progression, and management of adverse effects. Through a sharpened focus on both precision medicine and competent prescription management, VIONE is a viable opportunity for investing in the zero-harm philosophy that is integral to an HRO.

Design and Implementation 

Initially launched in 2016 in a 15-bed inpatient, subacute rehabilitation unit within a VHA tertiary care facility, VIONE has been sustained and gradually expanded to 38 other VHA facility programs (Figure 2). Recognizing the potential value if adopted into widespread use, VIONE was a Gold Status winner in the VHA Under Secretary for Health Shark Tank-style competition in 2017 and was selected by the VHA Diffusion of Excellence as an innovation worthy of scale and spread through national dissemination.⁹ A toolkit for VIONE implementation, patient and provider brochures, VIONE vignette, and National Dialog template also have been created.¹⁰

Implementing VIONE in a new facility requires an actively engaged core team committed to patient safety and reduction of polypharmacy and PIM, interest and availability to lead project implementation strategies, along with meaningful local organizational support. The current structure for VIONE spread is as follows:

• Interested VHA participants review information and contact vavione@va.gov.
• The VIONE team orients implementing champions, mainly pharmacists, physicians, nurse practitioners, and physician assistants at a facility program level, offering guidance and available resources.
• Clinical Application Coordinators at Central Arkansas VA Healthcare System and participating facilities collaborate to add deprescribing menu options in CPRS and install the VIONE Polypharmacy Reminder Dialog template.
• Through close and ongoing collaborations, medical providers and clinical pharmacists proceed with deprescribing, aiming at planned cessation of nonessential and PIM, using the mnemonic prompt of VIONE. Vital and Important medications are continued and consolidated while a methodical plan is developed to deprescribe any medications that could lead to more harm than benefit and qualify based on the filters of Optional, Not indicated, and Every medicine has a diagnosis/reason. They select the proper discontinuation reasons in the CPRS medication menu (Figure 3) and document the rationale in the progress notes. It is highly encouraged that the collaborating pharmacists and health care providers add each other as cosigners and communicate effectively. Clinical pharmacy specialists also use the VIONE Polypharmacy Reminder Dialog Template (RDT) to document complete medication reviews with veterans to include deprescribing rationale and document shared decision making.

• A VIONE national dashboard captures deprescribing data in real time and automates reporting with daily updates that are readily accessible to all implementing facilities. Minimum data captured include the number of unique veterans impacted, number of medications deprescribed, cumulative cost avoidance to date, and number of prescriptions deprescribed per veteran. The dashboard facilitates real-time use of individual patient data and has also been designed to capture data from VHA administrative data portals and Corporate Data Warehouse.

Results

As of October 31, 2019, the assessment of polypharmacy using the VIONE tool across VHA sites has benefited > 60,000 unique veterans, of whom 49.2% were in urban areas, 47.7% in rural areas, and 3.1% in highly rural areas. Elderly male veterans comprised a clear majority. More than 128,000 medications have been deprescribed. The top classes of medications deprescribed are antihypertensives, over-the-counter medications, and antidiabetic medications. An annualized cost avoidance of > $4.0 million has been achieved. Cost avoidance is the cost of medications that otherwise would have continued to be filled and paid for by the VHA if they had not been deprescribed, projected for a maximum of 365 days. The calculation methodology can be summarized as follows:

The calculations reported in Table 3 and Figure 4 are conservative and include only chronic outpatient prescriptions and do not account for medications deprescribed in inpatient units, nursing home, community living centers, or domiciliary populations. Data tracked separately from inpatient and community living center patient populations indicated an additional 25,536 deprescribed medications, across 28 VA facilities, impacting 7,076 veterans with an average 2.15 medications deprescribed per veteran. The additional achieved cost avoidance was $370,272 (based on $14.50 average cost per prescription). Medications restarted within 30 days of deprescribing are not included in these calculations.

The cost avoidance calculation further excludes the effects of VIONE implementation on many other types of interventions. These interventions include, but are not limited to, changing from aggressive care to end of life, comfort care when strongly indicated; reduced emergency department visits or invasive diagnostic and therapeutic approaches, when not indicated; medical supplies, antimicrobial preparations; labor costs related to packaging, mailing, and administering prescriptions; reduced/prevented clinical waste; reduced decompensation of systemic illnesses and subsequent health care needs precipitated by iatrogenic disturbances and prolonged convalescence; and overall changes to prescribing practices through purposeful and targeted interactions with colleagues across various disciplines and various hierarchical levels.

Discussion

The VIONE clinical program exemplifies the translation of HRO principles into health care system practices. VIONE offers a systematic approach to improve medication management with an emphasis on deprescribing nonessential medications across various health care settings, facilitating VHA efforts toward zero harm. It demonstrates close alignment with the key building blocks of an HRO. Effective VIONE incorporation into an organizational culture reflects leadership commitment to safety and reliability in their vision and actions. By empowering staff to proactively reduce inappropriate medications and thereby prevent patient harm, VIONE contributes to enhancing an enterprise-wide culture of safety, with fewer errors and greater reliability. As a standardized decision support tool for the ongoing practice of assessment and planned cessation of potentially inappropriate medications, VIONE illustrates how continuous process improvement can be a part of staff-engaged, veteran-centered, highly reliable care. The standardization of the VIONE tool promotes achievement and sustainment of desired HRO principles and practices within health care delivery systems.

Conclusions

The VIONE program was launched not as a cost savings or research program but as a practical, real-time bedside or ambulatory care intervention to improve patient safety. Its value is reflected in the overwhelming response from scholarly and well-engaged colleagues expressing serious interests in expanding collaborations and tailoring efforts to add more depth and breadth to VIONE related efforts.

As of October 31, 2019, the assessment of polypharmacy using the VIONE tool across VHA sites has benefited > 60,000 unique veterans, of whom 49.2% were in urban areas, 47.7% in rural areas, and 3.1% in highly rural areas. Elderly male veterans comprised a clear majority. More than 128,000 medications have been deprescribed. The top classes of medications deprescribed are antihypertensives, over-the-counter medications, and antidiabetic medications. An annualized cost avoidance of > $4.0 million has been achieved. Cost avoidance is the cost of medications that otherwise would have continued to be filled and paid for by the VHA if they had not been deprescribed, projected for a maximum of 365 days. The calculation methodology can be summarized as follows:

The calculations reported in Table 3 and Figure 4 are conservative and include only chronic outpatient prescriptions and do not account for medications deprescribed in inpatient units, nursing home, community living centers, or domiciliary populations. Data tracked separately from inpatient and community living center patient populations indicated an additional 25,536 deprescribed medications, across 28 VA facilities, impacting 7,076 veterans with an average 2.15 medications deprescribed per veteran. The additional achieved cost avoidance was $370,272 (based on $14.50 average cost per prescription). Medications restarted within 30 days of deprescribing are not included in these calculations.

The cost avoidance calculation further excludes the effects of VIONE implementation on many other types of interventions. These interventions include, but are not limited to, changing from aggressive care to end of life, comfort care when strongly indicated; reduced emergency department visits or invasive diagnostic and therapeutic approaches, when not indicated; medical supplies, antimicrobial preparations; labor costs related to packaging, mailing, and administering prescriptions; reduced/prevented clinical waste; reduced decompensation of systemic illnesses and subsequent health care needs precipitated by iatrogenic disturbances and prolonged convalescence; and overall changes to prescribing practices through purposeful and targeted interactions with colleagues across various disciplines and various hierarchical levels.

Discussion

The VIONE clinical program exemplifies the translation of HRO principles into health care system practices. VIONE offers a systematic approach to improve medication management with an emphasis on deprescribing nonessential medications across various health care settings, facilitating VHA efforts toward zero harm. It demonstrates close alignment with the key building blocks of an HRO. Effective VIONE incorporation into an organizational culture reflects leadership commitment to safety and reliability in their vision and actions. By empowering staff to proactively reduce inappropriate medications and thereby prevent patient harm, VIONE contributes to enhancing an enterprise-wide culture of safety, with fewer errors and greater reliability. As a standardized decision support tool for the ongoing practice of assessment and planned cessation of potentially inappropriate medications, VIONE illustrates how continuous process improvement can be a part of staff-engaged, veteran-centered, highly reliable care. The standardization of the VIONE tool promotes achievement and sustainment of desired HRO principles and practices within health care delivery systems.

Conclusions

The VIONE program was launched not as a cost savings or research program but as a practical, real-time bedside or ambulatory care intervention to improve patient safety. Its value is reflected in the overwhelming response from scholarly and well-engaged colleagues expressing serious interests in expanding collaborations and tailoring efforts to add more depth and breadth to VIONE related efforts.

High reliability organizations (HROs) incorporate continuous process improvement through leadership commitment to create a safety culture that works toward creating a zero-harm environment.¹ The Veterans Health Administration (VHA) has set transformational goals for becoming an HRO. In this article, we describe VIONE, an expanding medication deprescribing clinical program, which exemplifies the translation of HRO principles into health care system models. Both VIONE and HRO are globally relevant.

Reducing medication errors and related adverse drug events are important for achieving zero harm. Preventable medical errors rank behind heart disease and cancer as the third leading cause of death in the US.² The simultaneous use of multiple medications can lead to dangerous drug interactions, adverse outcomes, and challenges with adherence. When a person is taking multiple medicines, known as polypharmacy, it is more likely that some are potentially inappropriate medications (PIM). Current literature highlights the prevalence and dangers of polypharmacy, which ranks among the top 10 common causes of death in the US, as well as suggestions to address preventable adverse outcomes from polypharmacy and PIM.^3-5

Deprescribing of PIM frequently results in better disease management with improved health outcomes and quality of life.⁴ Many health care settings lack standardized approaches or set expectations to proactively deprescribe PIM. There has been insufficient emphasis on how to make decisions for deprescribing medications when therapeutic benefits are not clear and/or when the adverse effects may outweigh the therapeutic benefits.⁵

It is imperative to provide practice guidance for deprescribing nonessential medications along with systems-based infrastructure to enable integrated and effective assessments during opportune moments in the health care continuum. Multimodal approaches that include education, risk stratification, population health management interventions, research and resource allocation can help transform organizational culture in health care facilities toward HRO models of care, aiming at zero harm to patients.

The practical lessons learned from VIONE implementation science experiences on various scales and under diverse circumstances, cumulative wisdom from hindsight, foresight and critical insights gathered during nationwide spread of VIONE over the past 3 years continues to propel us toward the desirable direction and core concepts of an HRO.

The VIONE program facilitates practical, real-time interventions that could be tailored to various health care settings, organizational needs, and available resources. VIONE implements an electronic Computerized Patient Record System (CPRS) tool to enable planned cessation of nonessential medications that are potentially harmful, inappropriate, not indicated, or not necessary. The VIONE tool supports systematic, individualized assessment and adjustment through 5 filters (Figure 1). It prompts providers to assign 1 of these filters intuitively and objectively. VIONE combines clinical evidence for best practices, an interprofessional team approach, patient engagement, adapted use of existing medical records systems, and HRO principles for effective implementation.

As a tool to support safer prescribing practices, VIONE aligns closely with HRO principles (Table 1) and core pillars (Table 2).^6-8 A zero-harm safety culture necessitates that medications be used for correct reasons, over a correct duration of time, and following a correct schedule while monitoring for adverse outcomes. However, reality generally falls significantly short of this for a myriad of reasons, such as compromised health literacy, functional limitations, affordability, communication gaps, patients seen by multiple providers, and an accumulation of prescriptions due to comorbidities, symptom progression, and management of adverse effects. Through a sharpened focus on both precision medicine and competent prescription management, VIONE is a viable opportunity for investing in the zero-harm philosophy that is integral to an HRO.

Design and Implementation 

Initially launched in 2016 in a 15-bed inpatient, subacute rehabilitation unit within a VHA tertiary care facility, VIONE has been sustained and gradually expanded to 38 other VHA facility programs (Figure 2). Recognizing the potential value if adopted into widespread use, VIONE was a Gold Status winner in the VHA Under Secretary for Health Shark Tank-style competition in 2017 and was selected by the VHA Diffusion of Excellence as an innovation worthy of scale and spread through national dissemination.⁹ A toolkit for VIONE implementation, patient and provider brochures, VIONE vignette, and National Dialog template also have been created.¹⁰

Implementing VIONE in a new facility requires an actively engaged core team committed to patient safety and reduction of polypharmacy and PIM, interest and availability to lead project implementation strategies, along with meaningful local organizational support. The current structure for VIONE spread is as follows:

• Interested VHA participants review information and contact vavione@va.gov.
• The VIONE team orients implementing champions, mainly pharmacists, physicians, nurse practitioners, and physician assistants at a facility program level, offering guidance and available resources.
• Clinical Application Coordinators at Central Arkansas VA Healthcare System and participating facilities collaborate to add deprescribing menu options in CPRS and install the VIONE Polypharmacy Reminder Dialog template.
• Through close and ongoing collaborations, medical providers and clinical pharmacists proceed with deprescribing, aiming at planned cessation of nonessential and PIM, using the mnemonic prompt of VIONE. Vital and Important medications are continued and consolidated while a methodical plan is developed to deprescribe any medications that could lead to more harm than benefit and qualify based on the filters of Optional, Not indicated, and Every medicine has a diagnosis/reason. They select the proper discontinuation reasons in the CPRS medication menu (Figure 3) and document the rationale in the progress notes. It is highly encouraged that the collaborating pharmacists and health care providers add each other as cosigners and communicate effectively. Clinical pharmacy specialists also use the VIONE Polypharmacy Reminder Dialog Template (RDT) to document complete medication reviews with veterans to include deprescribing rationale and document shared decision making.

• A VIONE national dashboard captures deprescribing data in real time and automates reporting with daily updates that are readily accessible to all implementing facilities. Minimum data captured include the number of unique veterans impacted, number of medications deprescribed, cumulative cost avoidance to date, and number of prescriptions deprescribed per veteran. The dashboard facilitates real-time use of individual patient data and has also been designed to capture data from VHA administrative data portals and Corporate Data Warehouse.

Sequential chemoradiotherapy (CRT) and immunotherapy is safe, well tolerated, and efficacious among patients with locally advanced cervical cancer being treated with curative intent, a multicenter phase 1 trial suggests.

Less than 10% of patients treated with this sequence experienced a grade 3 toxicity. Meanwhile, more than 80% were alive and free of disease progression at 1 year.

“Despite standard CRT, most women with lymph node–positive cervical cancer experience disease recurrence,” note the investigators, led by Jyoti S. Mayadev, MD, associate professor in the department of radiation medicine and applied sciences, University of California, San Diego, in La Jolla. “Our study is potentially transformative in the standard treatment schema of locally advanced cervical cancer, with the prospect for immuno-oncology to add durable survival in patients with node-positive disease, a current unmet oncologic need.”

The investigators enrolled in the trial 32 women from Gynecology Oncology Cooperative Group member institutions who had stage IB2 to IVA cervical cancer with positive pelvic and/or para-aortic lymph nodes. Treatment consisted of six weekly doses of cisplatin, 40 mg/m², concurrent with extended-field, 3-dimensional conformal radiotherapy, followed by the immune checkpoint inhibitor ipilimumab (Yervoy) every 21 days for four cycles.

Results reported in JAMA Oncology showed that all 32 patients completed CRT and 21 patients went on to receive ipilimumab. Among the latter, 86% completed all four planned cycles and the rest completed two cycles.

In the group receiving sequential CRT and ipilimumab, 9.5% experienced grade 3 toxicity (lipase increase in one case and dermatitis in another case). Both toxicities were self-limited.

With a 14.8-month median follow-up, the patients treated with CRT-ipilimumab had a 12-month overall survival rate of 90%, and a 12-month progression-free survival rate of 81% (median durations were not reached). Neither human papillomavirus genotype nor HLA subtype was associated with these outcomes.

Translational analyses showed that patients experienced an increase in peripheral blood T cells expressing programmed cell death 1 (PD-1) after CRT that was then sustained with ipilimumab therapy. “[T]he use of an immune checkpoint inhibitor could stimulate the antitumor activity of tumor-specific cytotoxic T cells and augment radiation-induced neoantigen load,” the investigators proposed.

“To our knowledge, this phase 1 study is the first to show tolerability with a signal of efficacy of an immune check-point inhibitor ... as a part of the definitive treatment of locally advanced cervical cancer,” they concluded. “Our findings show promise for the use of immunotherapy in the definitive setting of locally advanced, node-positive cervical cancer; patients with this cancer historically have a poor prognosis with standard therapy alone.”
