Lanifibranor is a pan–peroxisome proliferator–activated receptor agonist that modulates metabolic and inflammatory pathways. In this 24-week, phase 2b, placebo-controlled trial involving patients with NASH, 1200 mg of lanifibranor, but not 800 mg, significantly improved histologic features of NASH. Weight gain, anemia, peripheral edema, diarrhea, and nausea occurred more frequently with lanifibranor than with placebo.

Abrocitinib, an oral selective Janus kinase 1 inhibitor, was effective and well tolerated in adults with moderate-to-severe atopic dermatitis in a phase 2b trial. We aimed to assess the efficacy and safety of abrocitinib monotherapy in adolescents and adults with moderate-to-severe atopic dermatitis. In this multicentre, double-blind, randomised phase 3 trial (JADE MONO-1), patients (aged ≥12 years) with moderate-to-severe atopic dermatitis (Investigator Global Assessment score ≥3, Eczema Area and Severity Index [EASI] score ≥16, percentage of body surface area affected ≥10%, and Peak Pruritus Numerical Rating Scale score ≥4) with a bodyweight of 40 kg or more, were enrolled at 69 sites in Australia, Canada, Europe, and the USA. Patients were randomly assigned (2:2:1) to oral abrocitinib 100 mg, abrocitinib 200 mg, or placebo once daily for 12 weeks. Randomisation was done using an interactive response technology system, stratified by baseline disease severity and age. Patients, investigators, and the funder of the study were masked to study treatment. The coprimary endpoints were the proportion of patients who had achieved an Investigator Global Assessment response (score of 0 [clear] or 1 [almost clear] with a ≥2-grade improvement from baseline), and the proportion of patients who achieved at least a 75% improvement in EASI score from baseline (EASI-75) score, both assessed at week 12. Efficacy was assessed in the full analysis set, which included all randomised patients who received at least one dose of study medication. Safety was assessed in all randomised patients. This study is registered with ClinicalTrials.gov, NCT03349060. Between Dec 7, 2017, and March 26, 2019, 387 patients were enrolled: 156 were assigned to abrocitinib 100 mg, 154 to abrocitinib 200 mg, and 77 to placebo. All enrolled patients received at least one dose of study treatment and thus were evaluable for 12-week efficacy. Of the patients with available data for the coprimary endpoints at week 12, the proportion of patients who had achieved an Investigator Global Assessment response was significantly higher in the abrocitinib 100 mg group than in the placebo group (37 [24%] of 156 patients vs six [8%] of 76 patients; p=0·0037) and in the abrocitinib 200 mg group compared with the placebo group (67 [44%] of 153 patients vs six [8%] of 76 patients; p<0·0001). Of the patients with available data for the coprimary endpoints at week 12, compared with the placebo group, the proportion of patients who had achieved an EASI-75 response was significantly higher in the abrocitinib 100 mg group (62 [40%] of 156 patients vs nine [12%] of 76 patients; p<0·0001) and abrocitinib 200 mg group (96 [63%] of 153 patients vs nine [12%] of 76 patients; p<0·0001). Adverse events were reported in 108 (69%) of 156 patients in the abrocitinib 100 mg group, 120 (78%) of 154 patients in the abrocitinib 200 mg group, and 44 (57%) of 77 patients in the placebo group. Serious adverse events were reported in five (3%) of 156 patients in the abrocitinib 100 mg group, five (3%) of 154 patients in the abrocitinib 200 mg group, and three (4%) of 77 patients in the placebo group. No treatment-related deaths were reported. Monotherapy with oral abrocitinib once daily was effective and well tolerated in adolescents and adults with moderate-to-severe atopic dermatitis. Pfizer.

An oral inhibitor of BCL2 produces substantial responses in the majority of patients with refractory chronic lymphocytic leukemia. The agent is so effective that precautions are necessary to protect patients against the tumor lysis syndrome at therapy initiation. The landscape of treatment for relapsed chronic lymphocytic leukemia (CLL) has recently changed with the introduction of agents that inhibit intracellular B-cell receptor signaling. 1 , 2 Ibrutinib monotherapy 3 , 4 and idelalisib in combination with rituximab 5 induce responses in the majority of patients in whom chemoimmunotherapy has failed, and these patients have improved outcomes. Treatment is given indefinitely, and complete remission is uncommon, particularly in the first 2 years after the initiation of therapy. Persistent disease is a concern because of the potential development of resistance. 6 – 8 Although many responses are durable and may deepen over time, relapses accumulate with ongoing follow-up, . . .

In more than 400 older patients with AML who could not receive myeloablative therapy, the incidence of composite complete remission was higher (66.4% vs. 28.3) and the median overall survival was longer (14.7 vs. 9.6 months) among patients who received azacitidine plus venetoclax (a B-cell lymphoma 2 antagonist) than among those who received azacitidine alone.

ObjectiveTo establish the non-inferior efficacy of vonoprazan versus lansoprazole in the treatment of Asian patients with erosive oesophagitis (EO).DesignIn this phase III, double-blind, multicentre study, patients with endoscopically confirmed EO were randomised 1:1 to receive vonoprazan 20 mg or lansoprazole 30 mg, once daily for up to 8 weeks. The primary endpoint was EO healing rate at 8 weeks. The secondary endpoints were EO healing rates at 2 and 4 weeks. Safety endpoints included treatment-emergent adverse events (TEAEs).ResultsIn the vonoprazan (n=238) and lansoprazole (n=230) arms, 8-week EO healing rates were 92.4% and 91.3%, respectively (difference 1.1% (95% CI –3.822% to 6.087%)). The respective 2-week EO healing rates were 75.0% and 67.8% (difference 7.2% (95% CI –1.054% to 15.371%)), and the respective 4-week EO healing rates were 85.3% and 83.5% (difference 1.8% (95% CI –4.763% to 8.395%)). In patients with baseline Los Angeles classification grade C/D, 2-week, 4-week and 8-week EO healing rates were higher with vonoprazan versus lansoprazole (2 weeks: 62.2% vs 51.5%, difference 10.6% (95% CI –5.708% to 27.002%); 4 weeks: 73.3% vs 67.2%, difference 6.2% (95% CI –8.884 to 21.223); and 8 weeks: 84.0% vs 80.6%, difference 3.4% (95% CI –9.187% to 15.993%)). Overall, EO healing rates appeared higher with vonoprazan versus lansoprazole. TEAE rates were 38.1% and 36.6% in the vonoprazan and lansoprazole group, respectively.ConclusionOur findings demonstrate the non-inferior efficacy of vonoprazan versus lansoprazole in terms of EO healing rate at 8 weeks in this population. Safety outcomes were similar in the two treatment arms.Trial registration number NCT02388724.

BackgroundBaricitinib is an oral, reversible, selective Janus kinase 1 and 2 inhibitor.MethodsIn this phase III, double-blind 24-week study, 684 biologic disease-modifying antirheumatic drug (DMARD)-naïve patients with rheumatoid arthritis and inadequate response or intolerance to ≥1 conventional synthetic DMARDs were randomly assigned 1:1:1 to placebo or baricitinib (2 or 4 mg) once daily, stratified by region and the presence of joint erosions. Endpoint measures included American College of Rheumatology 20% response (ACR20, primary endpoint), Disease Activity Score (DAS28) and Simplified Disease Activity Index (SDAI) score ≤3.3.ResultsMore patients achieved ACR20 response at week 12 with baricitinib 4 mg than with placebo (62% vs 39%, p≤0.001). Compared with placebo, statistically significant improvements in DAS28, SDAI remission, Health Assessment Questionnaire-Disability Index, morning joint stiffness, worst joint pain and worst tiredness were observed. In a supportive analysis, radiographic progression of structural joint damage at week 24 was reduced with baricitinib versus placebo. Rates of adverse events during the treatment period and serious adverse events (SAEs), including serious infections, were similar among groups (SAEs: 5% for baricitinib 4 mg and placebo). One patient had an adverse event of tuberculosis (baricitinib 4 mg); one patient had an adverse event of non-melanoma skin cancer (baricitinib 4 mg). Two deaths and three major adverse cardiovascular events occurred (placebo). Baricitinib was associated with a decrease in neutrophils and increases in low-density and high-density lipoprotein.ConclusionsIn patients with rheumatoid arthritis and an inadequate response or intolerance to conventional synthetic DMARDs, baricitinib was associated with clinical improvement and inhibition of progression of radiographic joint damage.Trial registration numberNCT01721057; Results.

Respiratory syncytial virus is a common cause of illness and hospitalization, especially among infants and immunocompromised persons, but there are no accepted antiviral therapies. In this RSV challenge study, GS-5806, a new compound, showed activity against RSV. Respiratory syncytial virus (RSV) infection accounts for substantial morbidity and mortality among infants 1 – 7 and is the most common reason for hospitalization of infants in the United States, 8 with an even greater outpatient burden of disease. Estimates indicate that among children younger than 2 years of age, the annual rate of RSV-related hospitalization is 5.2 per 1000, the rate of emergency department encounters is 32 to 57 per 1000, and the rate of outpatient visits is 66 to 177 per 1000. 2 Among infants younger than 1 year of age, the risk of death from respiratory causes is increased by a . . .

Alopecia areata is a distressing disorder of hair loss that is mediated partly by cytokines dependent on Janus kinases. The JAK1 and JAK2 inhibitor baricitinib reduced the extent of hair loss in two randomized trials over a period of 36 weeks.

In a trial involving 1033 patients hospitalized with Covid-19, the addition of baricitinib to remdesivir was associated with shorter recovery time, particularly among patients receiving high-flow oxygen, and with a 30% higher odds of improvement at day 15 than remdesivir alone. Adverse events were less frequent with the combination therapy.

Objectives Ischaemic digital ulcers (DUs) are common in patients with systemic sclerosis (SSc) and are a cause of disease-related morbidity. In an earlier trial, treatment with bosentan, an oral endothelin receptor antagonist, reduced the occurrence of new DUs by 48%. The present study (RAPIDS-2, for ‘RAndomized, double-blind, Placebo-controlled study with bosentan on healing and prevention of Ischemic Digital ulcers in patients with systemic Sclerosis’) was conducted to more fully evaluate the effects of bosentan treatment on DUs associated with SSc. Methods This double-blind, placebo-controlled trial conducted at 41 centres in Europe and North America randomised 188 patients with SSc with at least 1 active DU (‘cardinal ulcer’) to bosentan 62.5 mg twice daily for 4 weeks and 125 mg twice daily thereafter for 20 weeks (n=98) or matching placebo (n=90; total 24 weeks). The two primary end points were the number of new DUs and the time to healing of the cardinal ulcer. Secondary end points included pain, disability and safety. Results Over 24 weeks, bosentan treatment was associated with a 30% reduction in the number of new DUs compared with placebo (mean±standard error: 1.9±0.2 vs 2.7±0.3 new ulcers; p=0.04). This effect was greater in patients who entered the trial with more DUs. There was no difference between treatments in healing rate of the cardinal ulcer or secondary end points of pain and disability. Peripheral oedema and elevated aminotransferases were associated with bosentan treatment. Conclusions Bosentan treatment reduced the occurrence of new DUs in patients with SSc but had no effect on DU healing. Bosentan was well tolerated and may be a useful adjunct in the management of patients with SSc with recurrent DUs.
