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 . . .

This preclinical, phase 2 report shows that VX-445, a CFTR potentiator when administered with tezacaftor and ivacaftor, improved lung function and reduced sweat chloride concentrations and symptoms in patients harboring one or two Phe508del alleles.

In a randomized trial, 1050 patients with cancer who had acute venous thromboembolism were assigned to receive either dalteparin or edoxaban for 6 to 12 months. Edoxaban was noninferior to dalteparin with respect to the outcome of recurrent venous thromboembolism or major bleeding.

The muscarinic receptor agonist xanomeline has antipsychotic properties without dopamine blockade. Cholinergic adverse events limit its use. When xanomeline was combined with trospium to limit peripheral effects, scores were better on measures of schizophrenia than were scores with placebo over a period of 5 weeks.

Daily use of atogepant (a small-molecule, calcitonin gene–related peptide receptor antagonist) at any of three doses resulted in greater reductions in migraine days per month over a period of 12 weeks than did placebo. Nausea and constipation were side effects in approximately 5% of the participants who received atogepant.

Elexacaftor–ivacaftor–tezacaftor therapy is efficacious in cystic fibrosis among patients with at least one copy of the Phe508del allele. In this trial involving patients with either a gating or residual function allele in addition to the Phe508del allele, elexacaftor–ivacaftor–tezacaftor improved lung function as compared with active control therapy.

In 6 to 10% of patients with acute myeloid leukemia, mutant isocitrate dehydrogenase 1 is thought to contribute to leukemogenesis. Ivosidenib is an oral inhibitor of mutant IDH1. In a randomized trial, event-free survival was significantly longer with ivosidenib and azacitidine than with placebo and azacitidine.

Alectinib, a potent ALK tyrosine kinase inhibitor, was more effective and somewhat less toxic than crizotinib when used as primary therapy in patients with ALK -positive non–small-cell lung cancer. Importantly, it reduced the risk of CNS relapse.

There are no systemic treatments for patients with hepatocellular carcinoma (HCC) whose disease progresses during sorafenib treatment. We aimed to assess the efficacy and safety of regorafenib in patients with HCC who have progressed during sorafenib treatment. In this randomised, double-blind, parallel-group, phase 3 trial done at 152 sites in 21 countries, adults with HCC who tolerated sorafenib (≥400 mg/day for ≥20 of last 28 days of treatment), progressed on sorafenib, and had Child-Pugh A liver function were enrolled. Participants were randomly assigned (2:1) by a computer-generated randomisation list and interactive voice response system and stratified by geographical region, Eastern Cooperative Oncology Group performance status, macrovascular invasion, extrahepatic disease, and α-fetoprotein level to best supportive care plus oral regorafenib 160 mg or placebo once daily during weeks 1–3 of each 4-week cycle. Investigators, patients, and the funder were masked to treatment assignment. The primary endpoint was overall survival (defined as time from randomisation to death due to any cause) and analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01774344. Between May 14, 2013, and Dec 31, 2015, 843 patients were screened, of whom 573 were enrolled and randomised (379 to regorafenib and 194 to placebo; population for efficacy analyses), and 567 initiated treatment (374 received regorafenib and 193 received placebo; population for safety analyses). Regorafenib improved overall survival with a hazard ratio of 0·63 (95% CI 0·50–0·79; one-sided p<0·0001); median survival was 10·6 months (95% CI 9·1–12·1) for regorafenib versus 7·8 months (6·3–8·8) for placebo. Adverse events were reported in all regorafenib recipients (374 [100%] of 374) and 179 (93%) of 193 placebo recipients. The most common clinically relevant grade 3 or 4 treatment-emergent events were hypertension (57 patients [15%] in the regorafenib group vs nine patients [5%] in the placebo group), hand–foot skin reaction (47 patients [13%] vs one [1%]), fatigue (34 patients [9%] vs nine patients [5%]), and diarrhoea (12 patients [3%] vs no patients). Of the 88 deaths (grade 5 adverse events) reported during the study (50 patients [13%] assigned to regorafenib and 38 [20%] assigned to placebo), seven (2%) were considered by the investigator to be related to study drug in the regorafenib group and two (1%) in the placebo group, including two patients (1%) with hepatic failure in the placebo group. Regorafenib is the only systemic treatment shown to provide survival benefit in HCC patients progressing on sorafenib treatment. Future trials should explore combinations of regorafenib with other systemic agents and third-line treatments for patients who fail or who do not tolerate the sequence of sorafenib and regorafenib.

Glioblastoma is a highly vascularised tumour and there are few treatment options after disease recurrence. Regorafenib is an oral multikinase inhibitor of angiogenic, stromal, and oncogenic receptor tyrosine kinases. We aimed to assess the efficacy and safety of regorafenib in the treatment of recurrent glioblastoma. REGOMA is a randomised, multicentre, open-label phase 2 trial done in ten centres in Italy. Eligible patients (aged ≥18 years) with histologically confirmed glioblastoma, Eastern Cooperative Oncology Group performance status 0 or 1, and documented disease progression after surgery followed by radiotherapy and temozolomide chemoradiotherapy were randomly assigned (1:1) by a web-based system, stratified by centre and surgery at recurrence (yes vs no), to receive regorafenib 160 mg once daily for the first 3 weeks of each 4-week cycle or lomustine 110 mg/m2 once every 6 weeks until disease progression, death, unacceptable toxicity, or consent withdrawal. The primary endpoint was overall survival in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02926222, and is currently in follow-up. Between Nov 27, 2015, and Feb 23, 2017, 124 patients were screened and 119 eligible patients were randomly assigned to receive regorafenib (n=59) or lomustine (n=60). Median follow-up was 15·4 months (IQR 13·8–18·1). At the analysis cutoff date, 99 (83%) of 119 patients had died: 42 (71%) of 59 in the regorafenib group and 57 (95%) of 60 in the lomustine group. Overall survival was significantly improved in the regorafenib group compared with the lomustine group, with a median overall survival of 7·4 months (95% CI 5·8–12·0) in the regorafenib group and 5·6 months (4·7–7·3) in the lomustine group (hazard ratio 0·50, 95% CI 0·33–0·75; log-rank p=0·0009). Grade 3–4 treatment-related adverse events occurred in 33 (56%) of 59 patients treated with regorafenib and 24 (40%) of 60 with lomustine. The most frequent grade 3 or 4 adverse events related to regorafenib were hand–foot skin reaction, increased lipase, and blood bilirubin increased (in six [10%] of 59 patients each). In the lomustine group, the most common grade 3 or 4 adverse events were decreased platelet count (eight [13%] of 60 patients), decreased lymphocyte count (eight [13%]), and neutropenia (seven [12%]). No death was considered by the investigators to be drug related. REGOMA showed an encouraging overall survival benefit of regorafenib in recurrent glioblastoma. This drug might be a new potential treatment for these patients and should be investigated in an adequately powered phase 3 study. Veneto Institute of Oncology and Bayer Italy.
