In a phase 3 trial, participants with early Alzheimer’s disease who received the monoclonal antibody lecanemab had less decline on measures of cognition and function at 18 months than those who received placebo.

Lenvatinib plus either pembrolizumab or everolimus was compared with sunitinib as first-line therapy for advanced renal cell cancer. Progression-free survival was significantly longer with lenvatinib plus pembrolizumab than with sunitinib. Lenvatinib plus everolimus was also more effective than sunitinib, but the difference was smaller.

A randomized trial compared standard chemotherapy plus dostarlimab or placebo. Patients with mismatch repair–deficient tumors had 2-year progression-free survival of 61.4% with dostarlimab and 15.7% with placebo.

Tezepelumab is a monoclonal antibody that blocks thymic stromal lymphopoietin, an epithelial-cell–derived cytokine implicated in the pathogenesis of asthma. This randomized, placebo-controlled clinical trial showed a reduction in the annualized rate of asthma exacerbations among patients with severe, uncontrolled asthma treated with tezepelumab.

In this 52-week randomized trial, the α 4 β 7 integrin antibody vedolizumab was effective in treating Crohn's disease. The incidence of serious adverse events was higher with vedolizumab than with placebo. Crohn's disease is a chronic inflammatory bowel disease. 1 Current treatments include glucocorticoids, immunosuppressive agents (i.e., azathioprine, mercaptopurine, or methotrexate), and tumor necrosis factor (TNF) antagonists. 1 – 3 Many patients do not have a response to therapy, 4 and treatments are associated with important toxic effects. 5 , 6 Natalizumab, a monoclonal antibody that modulates gut and brain lymphocyte migration by antagonizing α 4 β 1 and α 4 β 7 integrin–mediated interactions, 7 is efficacious in the treatment of multiple sclerosis 8 , 9 and Crohn's disease. 10 – 12 Its use in patients with Crohn's disease has been limited by the development in some patients of progressive multifocal . . .

A randomized, double-blind, placebo-controlled, 52-week study (no. NCT03068468) evaluated gosuranemab, an anti-tau monoclonal antibody, in the treatment of progressive supranuclear palsy (PSP). In total, 486 participants dosed were assigned to either gosuranemab ( n  = 321) or placebo ( n  = 165). Efficacy was not demonstrated on adjusted mean change of PSP Rating Scale score at week 52 between gosuranemab and placebo (10.4 versus 10.6, P  = 0.85, primary endpoint), or at secondary endpoints, resulting in discontinuation of the open-label, long-term extension. Unbound N-terminal tau in cerebrospinal fluid decreased by 98% with gosuranemab and increased by 11% with placebo ( P  < 0.0001). Incidences of adverse events and deaths were similar between groups. This well-powered study suggests that N-terminal tau neutralization does not translate into clinical efficacy. In the phase 2 PASSPORT study, treatment with the anti-tau antibody gosuranemab did not show clinical benefit in participants with supranuclear palsy, suggesting that N-terminal tau neutralization does not translate into clinical efficacy.

CD38-targeting immunotherapy is approved in combination with lenalidomide and dexamethasone in patients with newly diagnosed multiple myeloma (NDMM) that are transplant ineligible (TI) and is considered the best standard of care (SOC). To improve current SOC, we evaluated the added value of weekly bortezomib (V) to isatuximab plus lenalidomide and dexamethasone (IsaRd versus Isa-VRd). This Intergroupe Francophone of Myeloma phase 3 study randomized 270 patients with NDMM that were TI, aged 65–79 years, to IsaRd versus Isa-VRd arms. The primary endpoint was a minimal residual disease (MRD) negativity rate at 10 −5 by next-generation sequencing at 18 months from randomization. Key secondary endpoints included response rates, MRD assessment rates, survival and safety. The 18-month MRD negativity rates at 10 −5 were reported in 35 patients (26%, 95% confidence interval (CI) 19–34) in IsaRd versus 71 (53%, 95% CI 44–61) in Isa-VRd (odds ratio for MRD negativity 3.16, 95% CI 1.89–5.28, P  < 0.0001). The MRD benefit was consistent across subgroups at 10 −5 and 10 −6 , and was already observed at month 12. The proportion of patients with complete response or better at 18 months was higher with Isa-VRd (58% versus 33%; P  < 0.0001), as was the proportion of MRD negativity and complete response or better (37% versus 17%; P  = 0.0003). At a median follow-up of 23.5 months, no difference was observed for survival times (immature data). The addition of weekly bortezomib did not significantly affect the relative dose intensity of IsaRd. Isa-VRd significantly increased MRD endpoints, including the 18-month negativity rate at 10 −5 , the primary endpoint, compared with IsaRd. This study proposes Isa-VRd as a new SOC for patients with NDMM that are TI. ClinicalTrials.gov identifier: NCT04751877 . In patients with newly diagnosed, transplant-ineligible multiple myeloma, addition of weekly bortzomib to isatuximab, lenalidomide and dexamethasone leads to increased minimal residual disease negativity compared with isatuximab, lenalidomide and dexamethasone.

In this 52-week randomized trial, the α 4 β 7 integrin antibody vedolizumab was effective in treating ulcerative colitis. There were not significantly more adverse events with vedolizumab than with placebo, but the trial was not large or long enough to fully assess safety. Ulcerative colitis is a chronic inflammatory bowel disease characterized by symptoms of bloody diarrhea, abdominal cramps, and fatigue. 1 Current medical therapy has important limitations. Aminosalicylates 2 – 4 are only modestly effective; glucocorticoids can cause unacceptable adverse events and do not provide a benefit as maintenance therapy. Tumor necrosis factor (TNF) antagonists, although efficacious, 5 , 6 predispose patients to serious infection. 7 Thus, new treatment strategies are needed. The migration of leukocytes into inflamed intestinal tissue is highly regulated by specific molecular mechanisms. The α 4 β 7 integrin, 8 a cell-surface glycoprotein variably expressed on circulating B and T lymphocytes, interacts with mucosal addressin-cell . . .

In patients with asthma who had elevated blood eosinophil levels and marginal asthma control despite treatment with high-dose inhaled or oral glucocorticoids, asthma exacerbations were reduced in those receiving a monoclonal antibody that binds to and inactivates interleukin-5. Severe asthma affects less than 10% of patients with asthma and is associated with substantial morbidity and mortality and a large fraction of the health care costs among patients with asthma. 1 – 3 Despite available care, recurrent asthma exacerbations are a major issue in a subgroup of patients with eosinophilic airway inflammation. 4 – 6 Mepolizumab, a humanized monoclonal antibody against interleukin-5, selectively inhibits eosinophilic inflammation 7 , 8 and reduces the number of eosinophils in both sputum and blood, resulting in a reduction in exacerbations and in the need for treatment with systemic glucocorticoids. 7 – 12 In the Dose Ranging Efficacy and Safety with Mepolizumab . . .

We present the 6-year update of a phase 2 study evaluating the combination of obinutuzumab and idelalisib in relapse/refractory Waldenstrom macroglobulinemia. The results of the REMODEL trial demonstrated interesting efficacy in a high-risk genotype profile population. The primary endpoint was achieved with a median PFS of 25.4 months (95% CI, 15.7 to 29.0). However, a major limitation of idelalisib is its toxicity. With a median follow-up of 70.9 months, median OS was still not reached, and 5-year OS was 72.9% (95% CI, 61.3 to 86.6). We confirm that CXCR4 mutations had no impact on PFS or OS. However, TP53 mutated patients had shorter OS. At the time of analysis, six patients are alive without relapse and 40 had progressive disease. Among the 38 patients who received a new treatment, the median time to second progression was not reached in ibrutinib treated patients (n = 17) versus 30.8 months in patients treated with other options (95% CI, 16.9 to NA), p = 0.005. With longer follow-up our prospective study is the first to show an impact of TP53 mutations in patients treated with fixed duration chemo-free regimen leading to a significant shorter OS in this population. Moreover, ibrutinib remains an effective treatment after this combination. This study was registered on the clinicaltrial.gov web (NCT02962401, November 9, 2016).
