The ALK inhibitor crizotinib as first-line therapy was associated with a significantly better response rate, longer progression-free survival, and greater improvement in quality of life measures than standard chemotherapy in patients with ALK -positive lung cancer. Rearrangements of the anaplastic lymphoma kinase ( ALK ) gene are present in 3 to 5% of non–small-cell lung cancers (NSCLCs). 1 , 2 They define a distinct subgroup of NSCLC that typically occurs in younger patients who have never smoked or have a history of light smoking and that has adenocarcinoma histologic characteristics. 3 – 5 Crizotinib is an oral small-molecule tyrosine kinase inhibitor of ALK, MET, and ROS1 kinases. 6 In phase 1 and 2 studies, crizotinib treatment resulted in objective tumor responses in approximately 60% of patients with ALK -positive NSCLC and in progression-free survival of 7 to 10 months. 7 – 9 In . . .

In patients with venous thromboembolism at high risk of recurrence for whom extended treatment with direct oral anticoagulants has been indicated, the optimal dose is unknown. We aimed to assess efficacy and safety of reduced-dose versus full-dose direct oral anticoagulants in patients in whom extended anticoagulation has been indicated. RENOVE was a non-inferiority, investigator-initiated, multicentre, randomised, open-label, blinded endpoint trial done in 47 hospitals in France. Ambulatory patients aged 18 years or older with acute symptomatic venous thromboembolism (pulmonary embolism or proximal deep vein thrombosis) who had received 6–24 uninterrupted months of full-dose anticoagulation and for whom extended anticoagulation has been indicated were eligible. Eligible participants were categorised as having either a first unprovoked venous thromboembolism, recurrent venous thromboembolism, presence of persistent risk factors, or other clinical situations considered to be a high risk of recurrence. Participants were randomly assigned (1:1) to receive oral treatment with either a reduced dose of apixaban (2·5 mg twice daily) or rivaroxaban (10 mg once daily) or a full dose of apixaban (5 mg twice daily) or rivaroxaban (20 mg once daily) using a centralised randomisation procedure with an interactive web response system. The sequence generation method was a computerised random number generator and was balanced by blocks of different sizes. Randomisation was stratified by centre, type of direct oral anticoagulant, and antiplatelet drug. Physicians and participants were unmasked to treatment allocation; recurrent venous thromboembolism, clinically relevant bleeding, and all-cause death were adjudicated by an independent committee blinded to treatment allocation. The primary outcome was symptomatic recurrent venous thromboembolism, including recurrent fatal or non-fatal pulmonary embolism or isolated proximal deep vein thrombosis (non-inferiority hypothesis 90% power to exclude a hazard ratio [HR] of 1·7). The primary outcome and first two secondary outcomes were included in a hierarchical testing procedure. This trial is registered with ClinicalTrials.gov, NCT03285438. From Nov 2, 2017, to July 6, 2022, 2768 patients were enrolled and randomly assigned to the reduced-dose group (n=1383) or the full-dose group (n=1385). 970 (35·0%) participants were female, 1797 (65·0%) were male, and one (<0·1%) had sex not reported. Median follow-up was 37·1 months (IQR 24·0–48·3). Recurrent venous thromboembolism occurred in 19 of 1383 patients in the reduced-dose group (5-year cumulative incidence 2·2% [95% CI 1·1–3·3]) versus 15 of 1385 patients in the full-dose group (5-year cumulative incidence 1·8% [0·8–2·7]; adjusted HR 1·32 [95% CI 0·67–2·60]; absolute difference 0·40% [95% CI –1·05 to 1·85]; p=0·23 for non-inferiority). Major or clinically relevant bleeding occurred in 96 patients in the reduced-dose group (5-year cumulative incidence 9·9% [95% CI 7·7–12·1]) and 154 patients in the full-dose group (5-year cumulative incidence 15·2% [12·8–17·6]; adjusted HR 0·61 [95% CI 0·48–0·79]). 1136 (82·1%) of 1383 patients in the reduced-dose group and 1150 (83·0%) of 1385 in the full-dose group had an adverse event; 374 (27·0%) patients in the reduced-dose group and 420 (30·3%) in the full-dose group has a serious adverse event. 35 (5-year cumulative incidence 4·3% [95% CI 2·6–6·0]) patients in the reduced-dose group and 54 (5-year cumulative incidence 6·1% [4·3–8·0]) patients in the full-dose group died during the study period. In patients with venous thromboembolism requiring extended anticoagulation, reduction of the direct oral anticoagulant dose did not meet the non-inferiority criteria. However, the low recurrence rates in both groups and substantial reduction of clinically relevant bleeding with the reduced dose could support this regimen as an option. Further research will be needed to identify subgroups for whom the anticoagulation dose should not be reduced. French Ministry of Health.

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.

Triple treatment with elexacaftor, tezacaftor, and ivacaftor in patients with cystic fibrosis who had one Phe508del allele and a minimal-function mutation resulted in sustained improvement in FEV 1 , sweat chloride concentration, and the number of pulmonary exacerbations.

In animal models, cannabinoid-1 receptor (CB 1) blockade produces a lean phenotype, with resistance to diet-induced obesity and associated dyslipidaemia. We assessed the effect of rimonabant, a selective CB 1 blocker, on bodyweight and cardiovascular risk factors in overweight or obese patients. patients with body-mass index 30 kg/m 2 or greater, or body-mass index greater than 27 kg/m 2 with treated or untreated dyslipidaemia, hypertension, or both, were randomised to receive double-blind treatment with placebo, 5 mg rimonabant, or 20 mg rimonabant once daily in addition to a mild hypocaloric diet (600 kcal/day deficit). The primary efficacy endpoint was weight change from baseline after 1 year of treatment in the intention-to-treat population. Weight loss at 1 year was significantly greater in patients treated with rimonabant 5 mg (mean −3·4 kg [SD 5·7]; p=0·002 vs placebo) and 20 mg (−6·6 kg [7·2]; p<0·001 vs placebo) compared with placebo (−1·8 kg [6·4]). Significantly more patients treated with rimonabant 20 mg than placebo achieved weight loss of 5% or greater (p<0·001) and 10% or greater (p<0·001). Rimonabant 20 mg produced significantly greater improvements than placebo in waist circumference, HDL-cholesterol, triglycerides, and insulin resistance, and prevalence of the metabolic syndrome. The effects of rimonabant 5 mg were of less clinical significance. Rimonabant was generally well tolerated with mild and transient side effects. CB 1 blockade with rimonabant 20 mg, combined with a hypocaloric diet over 1 year, promoted significant decrease of bodyweight and waist circumference, and improvement in cardiovascular risk factors.

Cystic fibrosis transmembrane conductance regulator (CFTR) modulators correct the basic defect caused by CFTR mutations. Improvements in health outcomes have been achieved with the combination of a CFTR corrector and potentiator in people with cystic fibrosis homozygous for the F508del mutation. The addition of elexacaftor (VX-445), a next-generation CFTR corrector, to tezacaftor plus ivacaftor further improved F508del-CFTR function and clinical outcomes in a phase 2 study in people with cystic fibrosis homozygous for the F508del mutation. This phase 3, multicentre, randomised, double-blind, active-controlled trial of elexacaftor in combination with tezacaftor plus ivacaftor was done at 44 sites in four countries. Eligible participants were those with cystic fibrosis homozygous for the F508del mutation, aged 12 years or older with stable disease, and with a percentage predicted forced expiratory volume in 1 s (ppFEV1) of 40–90%, inclusive. After a 4-week tezacaftor plus ivacaftor run-in period, participants were randomly assigned (1:1) to 4 weeks of elexacaftor 200 mg orally once daily plus tezacaftor 100 mg orally once daily plus ivacaftor 150 mg orally every 12 h versus tezacaftor 100 mg orally once daily plus ivacaftor 150 mg orally every 12 h alone. The primary outcome was the absolute change from baseline (measured at the end of the tezacaftor plus ivacaftor run-in) in ppFEV1 at week 4. Key secondary outcomes were absolute change in sweat chloride and Cystic Fibrosis Questionnaire-Revised respiratory domain (CFQ-R RD) score. This study is registered with ClinicalTrials.gov, NCT03525548. Between Aug 3 and Dec 28, 2018, 113 participants were enrolled. Following the run-in, 107 participants were randomly assigned (55 in the elexacaftor plus tezacaftor plus ivacaftor group and 52 in the tezacaftor plus ivacaftor group) and completed the 4-week treatment period. The elexacaftor plus tezacaftor plus ivacaftor group had improvements in the primary outcome of ppFEV1 (least squares mean [LSM] treatment difference of 10·0 percentage points [95% CI 7·4 to 12·6], p<0·0001) and the key secondary outcomes of sweat chloride concentration (LSM treatment difference −45·1 mmol/L [95% CI −50·1 to −40·1], p<0·0001), and CFQ-R RD score (LSM treatment difference 17·4 points [95% CI 11·8 to 23·0], p<0·0001) compared with the tezacaftor plus ivacaftor group. The triple combination regimen was well tolerated, with no discontinuations. Most adverse events were mild or moderate; serious adverse events occurred in two (4%) participants receiving elexacaftor plus tezacaftor plus ivacaftor and in one (2%) receiving tezacaftor plus ivacaftor. Elexacaftor plus tezacaftor plus ivacaftor provided clinically robust benefit compared with tezacaftor plus ivacaftor alone, with a favourable safety profile, and shows the potential to lead to transformative improvements in the lives of people with cystic fibrosis who are homozygous for the F508del mutation.

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.

Amivantamab, an antibody against MET and EGFR, plus lazertinib, an EGFR tyrosine kinase inhibitor, induced a response in 86% of previously untreated patients and led to a median progression-free survival of nearly 2 years.

This companion article to the VX-445 report shows that VX-659, a new CFTR potentiator, when administered with tezacaftor and ivacaftor improved lung function, sweat chloride concentration, and symptoms in patients with cystic fibrosis who harbored one or two Phe508del alleles.

Both single-agent ibrutinib and chlorambucil plus obinutuzumab have shown superior efficacy to chlorambucil monotherapy and are standard first-line treatments in chronic lymphocytic leukaemia. We compared the efficacy of the combination of ibrutinib plus obinutuzumab with chlorambucil plus obinutuzumab in first-line chronic lymphocytic leukaemia or small lymphocytic lymphoma. iLLUMINATE is a multicentre, randomised, open-label, phase 3 trial done at 74 academic and community hospitals in Australia, Canada, Israel, New Zealand, Russia, Turkey, the EU, and the USA in patients with previously untreated chronic lymphocytic leukaemia or small lymphocytic lymphoma, either aged 65 years or older or younger than 65 years with coexisting conditions. Patients were randomly assigned (1:1) using a blocked randomisation schedule, stratified by Eastern Cooperative Oncology Group performance status and cytogenetics, to receive ibrutinib plus obinutuzumab (oral ibrutinib [420 mg once daily continuously] combined with intravenous obinutuzumab [100 mg on day 1, 900 mg on day 2, 1000 mg on day 8, and 1000 mg on day 15 of cycle 1 and on day 1 of subsequent 28-day cycles, for a total of six cycles]) or chlorambucil plus obinutuzumab (oral chlorambucil [0·5 mg/kg bodyweight on days 1 and 15 of each 28-day cycle for six cycles] combined with the same obinutuzumab regimen). Allocation concealment was achieved using an interactive web response system. Patients and investigators were not masked to treatment assignment. The primary endpoint was progression-free survival assessed by a masked independent review committee in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study treatment. This study is registered with ClinicalTrials.gov (NCT02264574), and patient enrolment is complete. Between Oct 6, 2014, and Oct 12, 2015, 229 patients were enrolled and randomly assigned to receive ibrutinib plus obinutuzumab (n=113) or chlorambucil plus obinutuzumab (n=116). After a median follow-up of 31·3 months (IQR 29·4–33·2), median progression-free survival was significantly longer in the ibrutinib plus obinutuzumab group (median not reached [95% CI 33·6–non-estimable]) than in the chlorambucil plus obinutuzumab group (19·0 months [15·1–22·1]; hazard ratio 0·23; 95% CI 0·15–0·37; p<0·0001). Estimated 30-month progression-free survival was 79% (95% CI 70–85) in the ibrutinib plus obinutuzumab group and 31% (23–40) in the chlorambucil plus obinutuzumab group. The most common grade 3 or 4 adverse events in both groups were neutropenia and thrombocytopenia. Serious adverse events occurred in 65 (58%) of 113 patients treated with ibrutinib plus obinutuzumab and 40 (35%) of 115 patients treated with chlorambucil plus obinutuzumab. Ibrutinib or chlorambucil treatment-related deaths were reported in one (1%) of 113 patients in the ibrutinib plus obinutuzumab group (sudden death) and one (1%) of 115 patients in the chlorambucil plus obinutuzumab group (neuroendocrine carcinoma of the skin). Ibrutinib plus obinutuzumab is an efficacious and safe chemotherapy-free combination treatment in previously untreated patients with chronic lymphocytic leukaemia or small lymphocytic lymphoma independent of high-risk features and provides an alternative first-line treatment option for these patients.
