At 12 weeks, the women treated with the antimuscarinic therapy showed a significant 12% greater decrease in urgency urinary incontinence (UUI) episodes per day and 11% greater decrease in total incontinence frequency, compared with the placebo group. They also had significantly less daytime and nighttime incontinence, and diurnal and nocturnal voiding frequency.

The antimuscarinic treatment was also associated with a significant 0.48 point improvement in Pittsburgh Sleep Quality Index score (P = .02), compared with the placebo group, as well as significant improvements in sleep duration and sleep efficiency subscales. However, there were no significant differences between the two groups in Epworth Sleepiness Scale scores.

“Both fewer voids at night and decreased urge incontinence reduce the number of awakenings during the night, which may be reflected in higher sleep efficiency and longer sleep duration,” wrote Qurratul A. Warsi, MBBS, of the University of California, San Francisco, and her coauthors.

Antimuscarinic medications such as fesoterodine may have a sedating effect, the authors noted, which could also improve the quality of sleep. The study also did not control for sleep disorders such as obstructive sleep apnea and restless leg syndrome.

“This analysis provides new data that indicate initiating pharmacologic treatment for UUI in ambulatory women is associated with improvement in important domains of sleep,” they wrote. “Among community-dwelling women with UUI, flexible-dose antimuscarinic therapy not only resulted in improvement in incontinence measures, but was also associated with significant improvements in overall quality of sleep, sleep duration, and sleep efficiency.”

Pfizer funded the study and provided the study medication. Four authors declared research grants from the pharmaceutical sector, including three who had received grants or consultancies from Pfizer. One author declared royalties and stipends from the publishing industry. No other conflicts of interest were declared.

CHMP recommends approval of emicizumab

Photo from Business Wire
Emicizumab (Hemlibra)

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended approval of emicizumab (Hemlibra®), a bispecific factor IXa- and factor X-directed antibody.

The recommendation is for emicizumab to be used as routine prophylaxis in patients of all ages who have hemophilia A with factor VIII inhibitors.

The marketing authorization application for emicizumab is being reviewed under accelerated assessment, a procedure granted to medicines the CHMP believes are of major interest for public health and therapeutic innovation.

The CHMP’s opinion on emicizumab will be reviewed by the European Commission (EC).

If the EC agrees with the CHMP, the commission will grant a centralized marketing authorization that will be valid in the European Union. Norway, Iceland, and Liechtenstein will make corresponding decisions on the basis of the EC’s decision.

The EC typically makes a decision within 67 days of the CHMP’s recommendation.

The CHMP’s recommendation for emicizumab is based on results from 2 phase 3 trials—HAVEN 1 and HAVEN 2.

Results from HAVEN 1 were published in NEJM and presented at the 26th ISTH Congress in July 2017. Updated results from HAVEN 2 were presented at the 2017 ASH Annual Meeting.

HAVEN 1

The study enrolled 109 patients (age 12 and older) with hemophilia A and FVIII inhibitors who were previously treated with bypassing agents (BPAs) on-demand or as prophylaxis.

The patients were randomized to receive emicizumab prophylaxis or no prophylaxis. On-demand treatment of breakthrough bleeds with BPAs was allowed.

There was a significant reduction in treated bleeds of 87% with emicizumab prophylaxis compared to no prophylaxis (95% CI: 72.3; 94.3, P<0.0001). And there was an 80% reduction in all bleeds with emicizumab (95% CI: 62.5; 89.8, P<0.0001).

Adverse events (AEs) occurring in at least 5% of patients treated with emicizumab were local injection site reactions, headache, fatigue, upper respiratory tract infection, and arthralgia.

Two patients experienced thromboembolic events (TEs), and 3 had thrombotic microangiopathy (TMA) while receiving emicizumab prophylaxis and more than 100 u/kg/day of activated prothrombin complex concentrate, on average, for 24 hours or more before the event. Two of these patients had also received recombinant factor VIIa.

Neither TE required anticoagulation therapy, and 1 patient restarted emicizumab. The cases of TMA observed were transient, and 1 patient restarted emicizumab.

HAVEN 2

In this single-arm trial, researchers evaluated emicizumab prophylaxis in 60 patients, ages 1 to 17, who had hemophilia A with FVIII inhibitors.

The efficacy analysis included 57 patients who were younger than 12. The 3 older patients were only included in the safety analysis.

Of the 57 patients, 64.9% had 0 bleeds, 94.7% had 0 treated bleeds, and 98.2% had 0 treated spontaneous bleeds and 0 treated joint bleeds. None of the patients had treated target joint bleeds.

Forty patients had a total of 201 AEs. The most common of these were viral upper respiratory tract infections (16.7%) and injection site reactions (16.7%).

There were no TEs or TMA events, and none of the patients tested positive for anti-drug antibodies. None of the 7 serious AEs in this trial were considered treatment-related.

VIDEO: COMPASS shows stroke-clot aspiration noninferior to retrieval

Article Type
Changed

 

– Clot removal in acute ischemic stroke patients using an aspiration catheter was noninferior to clot removal using the standard method, a stent retriever, in a multicenter, randomized trial with 270 patients.

“There is now level I evidence that stent retrievers and primary aspiration have equivalent outcomes in emergent large vessel occlusions,” J Mocco, MD, said at the International Stroke Conference, sponsored by the American Heart Association.

The results “will give physicians more choice,” Dr. Mocco said in a video interview. Until now, “many physicians felt that they had to use stent retrievers” because these devices had an much bigger evidence base of efficacy and safety. The new findings provide evidence that supports aspiration as an alternative strategy, said Dr. Mocco, professor of neurosurgery and director of the Cerebrovascular Center at Mount Sinai Medical Center in New York.

The results Dr. Mocco reported from the COMPASS trial (Comparison of Direct Aspiration vs. Stent Retriever as a First Approach) were the second time that clot aspiration was shown to produce outcomes similar to stent retrieval. Similar findings came from a French multicenter trial, ASTER, reported in 2017 (JAMA. 2017 Aug 1;318[5]:443-52).

The study ran at 15 U.S. centers during 2015-2017 and randomized patients with emergent large vessel occlusion strokes to receive initial treatment with either an aspiration catheter or a stent retriever. The specific type of catheter or stent used was left up to each operator. In 83% of the aspiration cases and 81% of the stent retriever cases, the initial device used produced a moderately high or better level of restored blood flow within the occluded artery, with thrombolysis in cerebral infarction (TICI) 2b flow or greater.

The study’s primary efficacy endpoint was the percentage of patients with a modified Rankin Scale score of 0-2 at 90 days after treatment, which occurred in 52% of patients treated with aspiration first and in 49% of those treated by retrieval first, which met the study’s prespecified criterion for noninferiority of the aspiration strategy, Dr. Mocco reported.

The results also showed suggestions of faster responses in the patients treated by aspiration first, although these did not reach statistical significance. The highest rate of restored blood flow within the occluded artery, TICI 3 flow, occurred in 34% of patients treated by aspiration first and in 23% of those treated with retrieval first. The average time to produce TICI 2b flow or greater was 22 minutes in the aspiration-first patients, compared with 33 minutes among retrieval-first patients.

“I prefer to start with aspiration first because it’s fast and efficient,” Dr. Mocco said. “I find encouragement in the nonsignificant faster rate of reperfusion” seen in the results.

Although Dr. Mocco highlighted operator preference when choosing aspiration or clot retrieval, “clot composition and underlying pathophysiology could potentially be important” considerations when selecting a strategy, commented Ralph L. Sacco, MD, professor and chairman of neurology at the University of Miami. “For cardioembolic, fresh clot, it makes sense that aspiration could be better. For atherosclerotic, fibrous clot, perhaps retrieval is better.”

The study’s safety endpoints, the rate of all-cause mortality after 90 days, all intracranial hemorrhages, and symptomatic intracranial hemorrhages, were all similar in the two study arms.

The COMPASS study was funded by Penumbra, but the company had no role in the trial’s design or analysis. Dr. Mocco has been a consultant to Cerebrotech Medical, EndoStream, Rebound Medical, Synchron, and Viseon and has investments in some of these companies. Dr. Sacco had no disclosures.

Experimental PD-1/PARP inhibitor combo shows promise in solid tumors

Article Type
Changed

 

– Combined therapy using an experimental programmed cell death protein 1 (PD-1) inhibitor and experimental poly ADP-ribose polymerase (PARP) 1/2 inhibitor was generally well tolerated and showed efficacy in a phase 1 study of patients with advanced solid tumors.

Tislelizumab, the anti–PD-1 agent in development for solid and hematologic malignancies, is a humanized IgG4 monoclonal antibody engineered to have minimal Fc-gamma receptor binding. Pamiparib, the PARP 1/2 inhibitor, is hypothesized to promote neoantigen release that may boost the efficacy of tislelizumab. At the Jan. 4 data cutoff, 2 of 49 patients treated with one of five planned dose levels experienced a complete response, 8 had a confirmed partial response, and 4 had an unconfirmed partial response, Linda Mileshkin, MD, reported at the ASCO-SITC Clinical Immuno-Oncology Symposium.

Thus, the objective response rate was 20%, she said, noting that the clinical benefit rate, which encompasses all those with a response as well as those with durable stable disease after at least 24 weeks, was 39%. The median duration of response was 168.5 days

As of the data cutoff, 11 patients, including all those with a complete or partial response, remained on treatment, and 10 patients remained on treatment beyond 200 days, said Dr. Mileshkin of Peter MacCallum Cancer Centre, Melbourne.

Study participants were 42 women and 7 men, with a mean age of 63 years and measurable disease treated with at least 1 prior line of therapy (median of 4), but with no prior exposure to a PARP inhibitor or PD-1 therapy. Primary tumor sites included ovarian/fallopian tube/peritoneal (34 patients); pancreas, prostate, and breast cancer (3 patients each); and bile duct, bladder, cervix, lung, peripheral nerve sheath, and uterus (1 patient each). For the current dose-finding phase of the study (phase 1a), cohorts of 6-13 patients were treated with either tislelizumab at an intravenous dose of 2 mg/kg every 3 weeks plus either an oral dose of 20, 40, or 60 mg of pamiparib (dose levels 1, 2, and 3, respectively), or with tislelizumab at an intravenous dose of 200 mg every 3 weeks plus pamiparib at an oral dose of 40 or 60 mg twice daily (dose levels 4 and 5, respectively), Dr. Mileshkin said.

Phase 1b will be a disease-specific expansion to evaluate preliminary antitumor activity.

The rationale for combining the two agents was “to prove that we could get some up-regulation of tumor-associated antigens by using a PARP inhibitor that may then allow us to improve the antitumor activity of the checkpoint inhibitor,” she said.

Further, the malignancies in the patients include those likely to harbor DNA damage repair deficiencies, she added.

All patients experienced at least one treatment-emergent adverse event; 21 experienced a serious event, and 23 had immune-related adverse events.

“Despite the number of events, most patients were able to continue therapy,” Dr. Mileshkin said, noting that more discontinuation was associated with the PD-1 therapy than with the PARP inhibitor.

Non–immune-related adverse events related to the PARP inhibitor included mostly grade 1 and 2 nausea, fatigue, and diarrhea. Anemia also occurred and was grade 3 in 12% of patients.

“In terms of the PD-1 therapy, we mostly saw grade 1 or 2 nonimmune adverse events and very few grade 3 and 4 events,” she said.

One or more grade 3 immune-related adverse events occurred in 12 patients, and based on reports from participating centers, there “seemed to be a signal here that we were seeing more hepatic toxicity than we might have expected,” she said, explaining that these included increases in transaminases and hepatitis.

“We ended up with 13 patients who had a hepatic adverse event thought to be related to treatment. The median time to onset was 55 days ... and there were 9 patients in whom these events were grade 3 or 4,” she said.

Ten had grade 2 or higher transaminitis, which was most likely autoimmune in nature.

“All of these patients were treated with corticosteroids, and they all recovered promptly from the event. Subsequently, the protocol was amended to try increase real-time hepatic safety monitoring,” she said, noting that the rate of hepatic events has fallen since these changes were made.

“We need to closely monitor that moving forward to try to understand it better,” she said of the hepatic events.

Dose level 4 (tislelizumab at 200 mg every 3 weeks plus pamiparib at 40 mg twice daily) was determined to be the maximum tolerated dose and is the recommended phase 2 dose, she noted.

“We were pleased to see 10 patients respond, with these responses appearing to be durable with this currently short follow-up period, and we look forward to seeing the results of part B,” she concluded, noting that enrollment of patients into disease-specific cohorts for that next phase is ongoing.

This study is sponsored by BeiGene. Dr. Mileshkin reported receiving payment for travel, accommodations, and/or expenses from BeiGene and Roche.

– Combined therapy using an experimental programmed cell death protein 1 (PD-1) inhibitor and experimental poly ADP-ribose polymerase (PARP) 1/2 inhibitor was generally well tolerated and showed efficacy in a phase 1 study of patients with advanced solid tumors.

Tislelizumab, the anti–PD-1 agent in development for solid and hematologic malignancies, is a humanized IgG4 monoclonal antibody engineered to have minimal Fc-gamma receptor binding. Pamiparib, the PARP 1/2 inhibitor, is hypothesized to promote neoantigen release that may boost the efficacy of tislelizumab. At the Jan. 4 data cutoff, 2 of 49 patients treated with one of five planned dose levels experienced a complete response, 8 had a confirmed partial response, and 4 had an unconfirmed partial response, Linda Mileshkin, MD, reported at the ASCO-SITC Clinical Immuno-Oncology Symposium.

Thus, the objective response rate was 20%, she said, noting that the clinical benefit rate, which encompasses all those with a response as well as those with durable stable disease after at least 24 weeks, was 39%. The median duration of response was 168.5 days

As of the data cutoff, 11 patients, including all those with a complete or partial response, remained on treatment, and 10 patients remained on treatment beyond 200 days, said Dr. Mileshkin of Peter MacCallum Cancer Centre, Melbourne.

Study participants were 42 women and 7 men, with a mean age of 63 years and measurable disease treated with at least 1 prior line of therapy (median of 4), but with no prior exposure to a PARP inhibitor or PD-1 therapy. Primary tumor sites included ovarian/fallopian tube/peritoneal (34 patients); pancreas, prostate, and breast cancer (3 patients each); and bile duct, bladder, cervix, lung, peripheral nerve sheath, and uterus (1 patient each). For the current dose-finding phase of the study (phase 1a), cohorts of 6-13 patients were treated with either tislelizumab at an intravenous dose of 2 mg/kg every 3 weeks plus either an oral dose of 20, 40, or 60 mg of pamiparib (dose levels 1, 2, and 3, respectively), or with tislelizumab at an intravenous dose of 200 mg every 3 weeks plus pamiparib at an oral dose of 40 or 60 mg twice daily (dose levels 4 and 5, respectively), Dr. Mileshkin said.

Barancik Prize winner to discuss MS biology advances

Article Type
Changed

 

Two decades ago, multiple sclerosis researchers like the University of Cambridge’s, Robin Franklin, PhD, understood the crucial role of regeneration of the myelin coating on nerve fibers, and they knew the process went awry in MS patients. But, he recalled, “we knew very little about how remyelination came about and the processes that orchestrated it.”

Now, thanks in part to the work of Dr. Franklin’s team, research into remyelination is making tremendous advances. “We’ve begun to understand the mechanisms that are operating, and that is fundamental to devising new therapies,” he said in an interview. “You don’t develop effective new therapies unless you understand the underlying biology. Now, we’re on the brink of that biology leading to regenerative medicine in MS.”

Dr. Robin Franklin
Dr. Franklin, professor of stem cell medicine at the Wellcome Trust-MRC Cambridge (England) Stem Cell Institute, will speak about the progress in myelin regeneration research when he delivers the Barancik Prize for Innovation in MS Research lecture Feb. 1 at a meeting of the Americas Committee for Treatment and Research in Multiple Sclerosis in San Diego.

Dr. Franklin is the winner of the international prize, which recognizes exceptional MS research and is administered by the National MS Society.

In recent years, Dr. Franklin and his colleagues have published multiple studies that reveal new details about the workings of myelin regeneration, especially the biology by which oligodendrocyte progenitor cells become new oligodendrocytes.

“There are simple steps in that process,” Dr. Franklin said. “What we’ve been able to do is decorate that simple model with a whole host of mechanisms that allow remyelination to take place.”

In 2011, Franklin and his colleagues published a study in rodents identifying the RXRg gene as a key promoter of remyelination, making it a potential target for therapy (Nat Neurosci. 2011;14:45-53).

“There’s still a lot more to be learned,” Dr. Franklin said, “but we’ve learned a sufficient amount that we can engage in a meaningful way with the pharmaceutical industry and MS clinicians to make regenerative medicines an effective component of the MS therapeutic armory.”

Dr. Franklin has no relevant disclosures.

Combination immunotherapy is active in dMMR/MSI-H metastatic colorectal cancer

Article Type
Changed

 

– Combination immunotherapy is efficacious for treating metastatic colorectal cancer that is deficient in mismatch repair (dMMR), giving rise to high microsatellite instability (MSI-H), according to the first report of results for the full cohort of the CheckMate-142 trial.

“Approximately 4% of patients with metastatic colorectal cancer have a deficiency in the DNA mismatch repair system. These patients benefit less from conventional chemotherapy than other patients,” lead investigator Thierry André, MD, chief of Medical Oncology at the Saint-Antoine Hospital, Paris, said at the 2018 GI Cancers Symposium.

Dr. Thierry André
In the nonrandomized phase 2 trial, patients with previously treated dMMR/MSI-H metastatic colorectal cancer were split into a 119-patient combination cohort given both nivolumab (Opdivo), which targets the receptor programmed death-1 (PD-1), and ipilimumab (Yervoy), which targets cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4), and a 74-patient monotherapy cohort given nivolumab alone.

Initial results for the latter cohort established a durable clinical benefit of nivolumab monotherapy, according to Dr. André. “It’s clear that there is a rationale to combine nivolumab and ipilimumab because they act synergistically to promote T-cell antitumor activity. Therefore, combination could further improve results,” he said.

With median follow-up of 13.4 months, 55% of patients had a response to the combination of nivolumab and ipilimumab, according to results reported at the symposium and simultaneously published (J Clin Oncol. 2018 Jan 20:JCO2017769901). Median progression-free and overall survival were not reached.

In addition, comparison with the nivolumab monotherapy cohort, albeit in nonrandomized fashion, suggested that addition of ipilimumab netted better outcomes.

“Nivolumab plus ipilimumab represents a promising new treatment option for patients with previously treated dMMR/MSI-H metastatic colorectal cancer,” Dr. André summarized. The results “are really very unusual in metastatic colorectal cancer, and we have a test, MSI, to select this population. It’s really a new hope for patients with metastatic colorectal cancer.”
 

Findings in context

“This is the largest study to date of anti-PD-1 and anti-CTLA-4 inhibitor combination in MSI-H colon cancer,” noted invited discussant Zsofia K. Stadler, MD, of Memorial Sloan Kettering Cancer Center in New York. Taken together, the results are promising.

“Is this sufficient evidence that combination therapy is superior to monotherapy with anti–PD-1? No. This trial was not intended for comparison or to show superiority,” she maintained. “This will require a large randomized comparison as has been done, for example, in melanoma. Even then, cost and value become important factors in the decision of whom to select for combination therapy.”

Dr. Zsofia K. Stadler
Rates of treatment-related adverse events and discontinuations due to such events with the combination were generally lower than those previously seen in other cancers, according to Dr. Stadler. Nonetheless, there is some added toxicity in going from monotherapy to combination therapy.

“Further studies are clearly needed to identify those particular subgroups of patients who may benefit from combination therapies, so can we predict which MSI-H patients may progress on monotherapy, and whether we can salvage patients on monotherapy who are not responding and are having progression of disease,” she concluded. “Those are important questions that need to be addressed.”
 

Study details

In CheckMate-142, the 55% overall response rate with the combination of nivolumab and ipilimumab consisted of complete response in 3.4% of patients and partial response in 51.3%, Dr. André reported at the symposium, sponsored by the American Gastroenterological Association, the American Society for Clinical Oncology, the American Society for Radiation Oncology, and the Society of Surgical Oncology. (The overall rate with nivolumab monotherapy at the same median follow-up was 31%, all partial responses.) The disease control rate was 80% with combination therapy (69% with monotherapy).

The combination achieved a similar response rate regardless of tumor PD-L1 expression and BRAF and KRAS mutational status. It was 71% in patients with a history of Lynch syndrome and 48% in those without such history.

The 12-month rates of progression-free survival and overall survival were 71% and 85%, respectively. “The PFS curve shows a plateau,” Dr. André pointed out. “This is a curve we dream about having in the first line. It’s very unusual to have that with a medical therapy in advanced disease.” (The corresponding rates with nivolumab monotherapy were 50% and 73%.)

Patients had significant, clinically meaningful improvements from baseline in quality of life with combination immunotherapy out to 91 weeks. “In my experience, this is really the first time I have had a very large number of patients going back to work in this very advanced disease,” he commented.

“No new safety signals or treatment-related deaths were reported,” Dr. André noted. The rate of treatment-related adverse events of grade 3 or 4 was 32% with the combination therapy (20% with monotherapy). The rate of events leading to discontinuation was 13% (7% with monotherapy).
 

 

 

Long-term outcomes with monotherapy

In a related presentation, Michael J. Overman, MD, an associate professor at the University of Texas MD Anderson Cancer Center, Houston, reported long-term outcomes with nivolumab monotherapy on CheckMate-142 according to prior lines of therapy.

Patients given monotherapy were classified as more heavily pretreated (at least three prior therapies, including a fluoropyrimidine, oxaliplatin, and irinotecan) and less heavily pretreated (at most two prior therapies, usually excluding irinotecan).

Dr. Michael J. Overman
Results for the entire monotherapy cohort now at a median 21 months of follow-up showed an overall response rate of 34% and a disease control rate of 62%, Dr. Overman reported. These compared with 32% and 64%, respectively, at the original 13 months of follow-up (Lancet Oncol. 2017;18:1182-91).

“Deepening of response was shown with further follow-up,” he noted; in particular, the rate of complete response increased from 3% to 9%. “This is primarily related to partial responses that have converted to complete responses with additional time.” Median duration of response was not reached.

The overall response rate was 26% in the more heavily pretreated group and 52% in the less heavily pretreated group, although confidence intervals overlapped. The disease control rate was 55% and 81%, respectively.

Both progression-free and overall survival curves for the entire monotherapy cohort showed a plateau. The 12-month rates were 44% (also 44% at 18 months) and 72% (67% at 18 months), respectively.

The rate of grade 3 or 4 treatment-related adverse events was 20%. “No new signals were seen with this longer follow-up,” Dr. Overman noted.

“Nivolumab continued to provide durable clinical benefit with long-term follow-up in previously treated patients with dMMR/MSI-H metastatic colorectal cancer. “Durable clinical benefit with deepening of response was observed regardless of prior chemotherapy with fluoropyrimidine, oxaliplatin, and irinotecan,” he summarized. “These results support ongoing evaluation of nivolumab-based therapy in the first-line setting in patients with deficient–mismatch repair colorectal cancer.”
 

Findings in context

“This secondary analysis is of interest, but this is an unplanned retrospective subgroup analysis of this data,” commented Dr. Stadler, the discussant. “I think the take-home message here is that both the heavily pretreated and not-so-heavily pretreated groups have clinical benefit from this therapy. Certainly, longer-term follow-up continues to support the use of nivolumab monotherapy in previously treated dMMR colorectal cancer.”

The findings for the whole nivolumab monotherapy cohort generally mirror those seen with pembrolizumab (Keytruda), another anti–PD-1 antibody, in this patient population, except for a shorter time to response with the former, she noted. “This suggests that both nivolumab and pembrolizumab are reasonable monotherapies in metastatic MSI-H colorectal cancer.”

“Evaluation of anti–PD-1 therapies in the first-line setting is certainly warranted,” Dr. Stadler concluded. “In fact, the KEYNOTE-177 trial is a phase 3 randomized study of pembrolizumab versus investigator-choice chemotherapy for mismatch repair–deficient colorectal cancer that is already investigating this question and that is nearing completion of accrual.”

Dr. Andre disclosed that he receives honoraria from Baxter, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Lilly, MSD Oncology, Novartis, Roche/Genentech, Sanofi, Servier, and Xbiotech; that he has a consulting or advisory role with Amgen, Bristol-Myers Squibb, HalioDX, MSD Oncology, Mundipharma, Roche/Genentech, and Servier; and that he receives travel expenses from Amgen, Bristol-Myers Squibb, and Roche/Genentech. Dr. Overman disclosed that he has a consulting or advisory role with Bristol-Myers Squibb, Merrimack, and Roche/Genentech, and receives research funding Amgen, Bristol-Myers Squibb, Celgene, MedImmune, Merck, and Roche. The trial was sponsored by Bristol-Myers Squibb.

“Further studies are clearly needed to identify those particular subgroups of patients who may benefit from combination therapies, so can we predict which MSI-H patients may progress on monotherapy, and whether we can salvage patients on monotherapy who are not responding and are having progression of disease,” she concluded. “Those are important questions that need to be addressed.”
 

Study details

In CheckMate-142, the 55% overall response rate with the combination of nivolumab and ipilimumab consisted of complete response in 3.4% of patients and partial response in 51.3%, Dr. André reported at the symposium, sponsored by the American Gastroenterological Association, the American Society for Clinical Oncology, the American Society for Radiation Oncology, and the Society of Surgical Oncology. (The overall rate with nivolumab monotherapy at the same median follow-up was 31%, all partial responses.) The disease control rate was 80% with combination therapy (69% with monotherapy).

The combination achieved a similar response rate regardless of tumor PD-L1 expression and BRAF and KRAS mutational status. It was 71% in patients with a history of Lynch syndrome and 48% in those without such history.

The 12-month rates of progression-free survival and overall survival were 71% and 85%, respectively. “The PFS curve shows a plateau,” Dr. André pointed out. “This is a curve we dream about having in the first line. It’s very unusual to have that with a medical therapy in advanced disease.” (The corresponding rates with nivolumab monotherapy were 50% and 73%.)

Patients had significant, clinically meaningful improvements from baseline in quality of life with combination immunotherapy out to 91 weeks. “In my experience, this is really the first time I have had a very large number of patients going back to work in this very advanced disease,” he commented.

“No new safety signals or treatment-related deaths were reported,” Dr. André noted. The rate of treatment-related adverse events of grade 3 or 4 was 32% with the combination therapy (20% with monotherapy). The rate of events leading to discontinuation was 13% (7% with monotherapy).
 

 

 

Long-term outcomes with monotherapy

In a related presentation, Michael J. Overman, MD, an associate professor at the University of Texas MD Anderson Cancer Center, Houston, reported long-term outcomes with nivolumab monotherapy on CheckMate-142 according to prior lines of therapy.

Patients given monotherapy were classified as more heavily pretreated (at least three prior therapies, including a fluoropyrimidine, oxaliplatin, and irinotecan) and less heavily pretreated (at most two prior therapies, usually excluding irinotecan).

Dr. Michael J. Overman
Results for the entire monotherapy cohort now at a median 21 months of follow-up showed an overall response rate of 34% and a disease control rate of 62%, Dr. Overman reported. These compared with 32% and 64%, respectively, at the original 13 months of follow-up (Lancet Oncol. 2017;18:1182-91).

“Deepening of response was shown with further follow-up,” he noted; in particular, the rate of complete response increased from 3% to 9%. “This is primarily related to partial responses that have converted to complete responses with additional time.” Median duration of response was not reached.

The overall response rate was 26% in the more heavily pretreated group and 52% in the less heavily pretreated group, although confidence intervals overlapped. The disease control rate was 55% and 81%, respectively.

Both progression-free and overall survival curves for the entire monotherapy cohort showed a plateau. The 12-month rates were 44% (also 44% at 18 months) and 72% (67% at 18 months), respectively.

The rate of grade 3 or 4 treatment-related adverse events was 20%. “No new signals were seen with this longer follow-up,” Dr. Overman noted.

“Nivolumab continued to provide durable clinical benefit with long-term follow-up in previously treated patients with dMMR/MSI-H metastatic colorectal cancer. “Durable clinical benefit with deepening of response was observed regardless of prior chemotherapy with fluoropyrimidine, oxaliplatin, and irinotecan,” he summarized. “These results support ongoing evaluation of nivolumab-based therapy in the first-line setting in patients with deficient–mismatch repair colorectal cancer.”
 

Findings in context

“This secondary analysis is of interest, but this is an unplanned retrospective subgroup analysis of this data,” commented Dr. Stadler, the discussant. “I think the take-home message here is that both the heavily pretreated and not-so-heavily pretreated groups have clinical benefit from this therapy. Certainly, longer-term follow-up continues to support the use of nivolumab monotherapy in previously treated dMMR colorectal cancer.”

The findings for the whole nivolumab monotherapy cohort generally mirror those seen with pembrolizumab (Keytruda), another anti–PD-1 antibody, in this patient population, except for a shorter time to response with the former, she noted. “This suggests that both nivolumab and pembrolizumab are reasonable monotherapies in metastatic MSI-H colorectal cancer.”

“Evaluation of anti–PD-1 therapies in the first-line setting is certainly warranted,” Dr. Stadler concluded. “In fact, the KEYNOTE-177 trial is a phase 3 randomized study of pembrolizumab versus investigator-choice chemotherapy for mismatch repair–deficient colorectal cancer that is already investigating this question and that is nearing completion of accrual.”

Dr. Andre disclosed that he receives honoraria from Baxter, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Lilly, MSD Oncology, Novartis, Roche/Genentech, Sanofi, Servier, and Xbiotech; that he has a consulting or advisory role with Amgen, Bristol-Myers Squibb, HalioDX, MSD Oncology, Mundipharma, Roche/Genentech, and Servier; and that he receives travel expenses from Amgen, Bristol-Myers Squibb, and Roche/Genentech. Dr. Overman disclosed that he has a consulting or advisory role with Bristol-Myers Squibb, Merrimack, and Roche/Genentech, and receives research funding Amgen, Bristol-Myers Squibb, Celgene, MedImmune, Merck, and Roche. The trial was sponsored by Bristol-Myers Squibb.

– Combination immunotherapy is efficacious for treating metastatic colorectal cancer that is deficient in mismatch repair (dMMR), giving rise to high microsatellite instability (MSI-H), according to the first report of results for the full cohort of the CheckMate-142 trial.

“Approximately 4% of patients with metastatic colorectal cancer have a deficiency in the DNA mismatch repair system. These patients benefit less from conventional chemotherapy than other patients,” lead investigator Thierry André, MD, chief of Medical Oncology at the Saint-Antoine Hospital, Paris, said at the 2018 GI Cancers Symposium.

Dr. Thierry André
In the nonrandomized phase 2 trial, patients with previously treated dMMR/MSI-H metastatic colorectal cancer were split into a 119-patient combination cohort given both nivolumab (Opdivo), which targets the receptor programmed death-1 (PD-1), and ipilimumab (Yervoy), which targets cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4), and a 74-patient monotherapy cohort given nivolumab alone.

Initial results for the latter cohort established a durable clinical benefit of nivolumab monotherapy, according to Dr. André. “It’s clear that there is a rationale to combine nivolumab and ipilimumab because they act synergistically to promote T-cell antitumor activity. Therefore, combination could further improve results,” he said.

With median follow-up of 13.4 months, 55% of patients had a response to the combination of nivolumab and ipilimumab, according to results reported at the symposium and simultaneously published (J Clin Oncol. 2018 Jan 20:JCO2017769901). Median progression-free and overall survival were not reached.

In addition, comparison with the nivolumab monotherapy cohort, albeit in nonrandomized fashion, suggested that addition of ipilimumab netted better outcomes.

“Nivolumab plus ipilimumab represents a promising new treatment option for patients with previously treated dMMR/MSI-H metastatic colorectal cancer,” Dr. André summarized. The results “are really very unusual in metastatic colorectal cancer, and we have a test, MSI, to select this population. It’s really a new hope for patients with metastatic colorectal cancer.”
 

Findings in context

“This is the largest study to date of anti-PD-1 and anti-CTLA-4 inhibitor combination in MSI-H colon cancer,” noted invited discussant Zsofia K. Stadler, MD, of Memorial Sloan Kettering Cancer Center in New York. Taken together, the results are promising.

“Is this sufficient evidence that combination therapy is superior to monotherapy with anti–PD-1? No. This trial was not intended for comparison or to show superiority,” she maintained. “This will require a large randomized comparison as has been done, for example, in melanoma. Even then, cost and value become important factors in the decision of whom to select for combination therapy.”

Dr. Zsofia K. Stadler
Rates of treatment-related adverse events and discontinuations due to such events with the combination were generally lower than those previously seen in other cancers, according to Dr. Stadler. Nonetheless, there is some added toxicity in going from monotherapy to combination therapy.

“Further studies are clearly needed to identify those particular subgroups of patients who may benefit from combination therapies, so can we predict which MSI-H patients may progress on monotherapy, and whether we can salvage patients on monotherapy who are not responding and are having progression of disease,” she concluded. “Those are important questions that need to be addressed.”

Medicaid expansion meant earlier presentation, better surgical outcomes

Article Type
Changed

 

The Patient Protection and Affordable Care Act’s Medicaid expansion led to increased coverage of patients, earlier presentation, and improved care for five common surgical conditions, according to a Jan. 24 report in JAMA Surgery.

“Given current debate on the ACA [Affordable Care Act] and reforms to the Medicaid program, evidence on the effects of these policies is critical ... As policy makers weigh changes to or a potential repeal of the ACA, these findings provide important new data on the early clinical effects of the law’s coverage expansion,” said investigators led by Andrew Loehrer, MD, of the department of surgical oncology at MD Anderson Cancer Center, Houston.

Dr. Andrew Loehrer

For a baseline, the team used hospital administrative data from the Vizient Clinical Data Base and Resource Manager to assess outcomes for appendicitis, cholecystitis, diverticulitis, peripheral artery disease, and aortic aneurysm in 42 states during 2010-2013, before the ACA took effect in 2014. They then compared outcomes during 2014-2015 in the 27 states that expanded Medicaid programs under the ACA with 15 states that did not. The study included 225,572 hospital admissions in the Medicaid expansion states and 67,957 in the nonexpansion states at more than 200 academic medical centers and affiliated hospitals.

Medicaid expansion in the 27 states was associated with a 7.5-percentage point decreased probability of patients being uninsured (95% confidence interval, –12.2 to –2.9; P = .002) and an 8.6-percentage point increased probability of having Medicaid (95% CI, 6.1-11.1; P less than .001).

Medicaid expansion was also associated with a 1.8-percentage point increase in the probability of early, uncomplicated presentation (95% CI, 0.7-2.9; P = .001) and a 2.6-percentage point increase in the probability of receiving optimal management after admission, most likely due to the earlier presentation (95% CI, 0.8-4.4; P = .006).

“Uncomplicated presentation” meant, for example, diverticulitis without abscess, fistula, or sepsis; unruptured aortic aneurysm; and peripheral artery disease without ulcerations or gangrene. Optimal management included cholecystectomy for acute cholecystitis; laparoscopic approaches for cholecystectomy or appendectomy; and limb salvage for peripheral artery disease.

The improvements were concentrated among Medicaid and uninsured patients, who were most likely to benefit from coverage expansion, rather than those with private insurance.

The investigators acknowledged the limitations of their data for tracking changes access and quality of care for surgical patients. “We recognize that the data on improved quality of care are not as clear. Our use of composite outcomes has specific limitations,” they wrote.

“As expected for the conditions studied, our analysis found no significant change in the overall number of individuals treated but rather a change in the timeliness in which individuals received care.” Meanwhile, “our sample revealed an increase in the percentage of surgical patients who were uninsured in nonexpansion states after 2014,” which was associated with “worsening of outcomes ... whereas expansion states had stabilization or improvement,” they said. In Medicaid expansion states, the number of uninsured dropped from 14.% to 6.8%, but in the nonexpansion states, the number of uninsured actually increased slightly from 21.2% to 21.9%.

There was no funding source reported for the study. The authors had no conflicts of interest.

CDC: Flu levels highest since pandemic year 2009

Article Type
Changed

 

Influenza activity continued to increase in the week ending Jan. 20, and the 2017-2018 flu season continues to look a lot like the 2009-2010 pandemic, according to data from the Centers for Disease Control and Prevention.

That season was dominated by influenza A (H3N2), and the 2017-2018 season seems to be going down that same path. For the week ending Jan. 20, the proportion of outpatient visits for influenza-like illness increased to 6.6%, which is, for the second consecutive week, the highest level reported since October of – you guessed it – 2009, when it hit 7.7%, the CDC said in its weekly flu surveillance report.

The level reported last week, 6.3%, has been revised downward and now stands at an even 6%.

It turns out that 2018 is something of a milestone for the H3N2 virus. The virus first emerged in 1968, so it has reached its 50th anniversary, Dan Jernigan, MD, director of the influenza division at the CDC’s National Center for Immunization and Respiratory Diseases, Atlanta, said on Jan. 26 in a weekly briefing.

H3N2 must not be happy about hitting the big 5-0, however, because the map of influenza-like illness activity looks pretty red and angry. For the week ending Jan. 20, there were 30 states at the highest level of flu activity on the CDC’s 1-10 scale, with another nine in the “high” range at levels 8 and 9.

Dr. Jernigan did suggest that activity may have peaked in some areas of the country, with California among them.

There were seven pediatric deaths reported for the week ending Jan. 20, although six occurred in previous weeks. There have been 37 flu-related deaths among children so far during the 2017-2018 season, the CDC said.

For the week ending Jan. 20, the proportion of outpatient visits for influenza-like illness increased to 6.6%, which is, for the second consecutive week, the highest level reported since October of – you guessed it – 2009, when it hit 7.7%, the CDC said in its weekly flu surveillance report.

The level reported last week, 6.3%, has been revised downward and now stands at an even 6%.

It turns out that 2018 is something of a milestone for the H3N2 virus. The virus first emerged in 1968, so it has reached its 50th anniversary, Dan Jernigan, MD, director of the influenza division at the CDC’s National Center for Immunization and Respiratory Diseases, Atlanta, said on Jan. 26 in a weekly briefing.

H3N2 must not be happy about hitting the big 5-0, however, because the map of influenza-like illness activity looks pretty red and angry. For the week ending Jan. 20, there were 30 states at the highest level of flu activity on the CDC’s 1-10 scale, with another nine in the “high” range at levels 8 and 9.

Dr. Jernigan did suggest that activity may have peaked in some areas of the country, with California among them.

There were seven pediatric deaths reported for the week ending Jan. 20, although six occurred in previous weeks. There have been 37 flu-related deaths among children so far during the 2017-2018 season, the CDC said.

Contrast nephropathy after computed tomography

Article Type
Changed

 

Clinical question: Do rates of acute kidney injury (AKI), renal replacement therapy (RRT), or mortality differ between adults receiving contrast-enhanced computed tomography (CT) versus those receiving noncontrast CT?

Background: Published estimates regarding the risk of postcontrast complications are highly variable and recent data show that the risk of postcontrast AKI may be lower than previously suggested.

Study design: Systematic review and meta-analysis..

Setting: Noninterventional studies assessing differences in AKI, new RRT, or mortality among adults who received contrast-enhanced CT, compared with those receiving noncontrast CT.

Synopsis: A search among six databases and Google Scholar from inception through 2016 yielded 28 observational studies meeting inclusion criteria that included 107,335 participants. Twenty-six assessed AKI, 13 assessed need for RRT, and 9 assessed all-cause mortality. Compared with noncontrast CT, contrast-enhanced CT was not significantly associated with AKI (odds ratio, 0.94; 95% confidence interval, 0.83-1.07), RRT (OR, 0.83; 95% CI 0.59-1.16), or all-cause mortality (OR, 1.0; 95% CI 0.73-1.36). The overall risk of bias ranged from low to serious among the included studies. Studies were observational in nature, they were conducted in multiple settings (for example, ICU, emergency department), and the baseline characteristics of included patients were highly variable.

Bottom line: This meta-analysis observed no difference in adverse events between patients receiving contrast-enhanced CT versus those receiving noncontrast CT but should be interpreted with caution given the observational nature of the studies and differing characteristics of the included patients and study settings.

FDA approves lutetium Lu 177 dotatate for GEP-NETs

Article Type
Changed

 



The Food and Drug Administration has approved the first radiopharmaceutical, lutetium Lu 177 dotatate (Lutathera), for the treatment of somatostatin receptor positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs), including foregut, midgut, and hindgut neuroendocrine tumors in adults.

Approval is based on two studies, including the phase 3, NETTER-1, that compared lutetium Lu 177 dotatate plus octreotide to octreotide alone, and a subset of patients from an expanded access program in the Netherlands in patients with somatostatin receptor positive tumors, the FDA said in a statement.

The NETTER-1 study included patients who had inoperable midgut NETs progressing under standard dose octreotide treatment and overexpressing somatostatin receptors. The primary endpoint was met, showing a 79% reduction in risk of disease progression or death in the study arm compared to the control (hazard ratio, 0.21, 95% confidence interval, 0.13-0.32, P less than. 0001). There was a 48% reduction in the estimated risk of death with lutetium Lu 177 dotatate treatment compared to treatment with octreotide alone at a preplanned interim overall survival analysis (hazard ratio, 0.52, 95% confidence interval, 0.32-0.84).

In the expanded access study, complete or partial tumor shrinkage was reported in 16% of the patients in the subset of 360 patients with GEP-NETs.

Common side effects include lymphopenia, increased GGT, AST and/or ALT, vomiting, nausea, hyperglycemia and hypokalemia.

Serious side effects include myelosuppression, secondary myelodysplastic syndrome and leukemia, renal toxicity, hepatotoxicity, neuroendocrine hormonal crises, and infertility. Patients taking lutetium Lu 177 dotatate are exposed to radiation and exposure of other patients, medical personnel, and household members should be limited in accordance with radiation safety practices, the FDA said.
