A comparison of sunitinib with cabozantinib, crizotinib, and savolitinib for treatment of advanced papillary renal cell carcinoma: a randomised, open-label, phase 2 trial.

MET (also known as hepatocyte growth factor receptor) signalling is a key driver of papillary renal cell carcinoma (PRCC). Given that no optimal therapy for metastatic PRCC exists, we aimed to compare an existing standard of care, sunitinib, with the MET kinase inhibitors cabozantinib, crizotinib, and savolitinib for treatment of patients with PRCC. We did a randomised, open-label, phase 2 trial done in 65 centres in the USA and Canada. Eligible patients were aged 18 years or older with metastatic PRCC who had received up to one previous therapy (excluding vascular endothelial growth factor-directed and MET-directed agents). Patients were randomly assigned to receive sunitinib, cabozantinib, crizotinib, or savolitinib, with stratification by receipt of previous therapy and PRCC subtype. All drug doses were administered orally: sunitinib 50 mg, 4 weeks on and 2 weeks off (dose reductions to 37·5 mg and 25 mg allowed); cabozantinib 60 mg daily (reductions to 40 mg and 20 mg allowed); crizotinib 250 mg twice daily (reductions to 200 mg twice daily and 250 mg once daily allowed); and savolitinib 600 mg daily (reductions to 400 mg and 200 mg allowed). Progression-free survival (PFS) was the primary endpoint. Analyses were done in an intention-to-treat population, with patients who did not receive protocol therapy excluded from safety analyses. This trial is registered with ClinicalTrials.gov, NCT02761057. Between April 5, 2016, and Dec 15, 2019, 152 patients were randomly assigned to one of four study groups. Five patients were identified as ineligible post-randomisation and were excluded from these analyses, resulting in 147 eligible patients. Assignment to the savolitinib (29 patients) and crizotinib (28 patients) groups was halted after a prespecified futility analysis; planned accrual was completed for both sunitinib (46 patients) and cabozantinib (44 patients) groups. PFS was longer in patients in the cabozantinib group (median 9·0 months, 95% CI 6-12) than in the sunitinib group (5·6 months, 3-7; hazard ratio for progression or death 0·60, 0·37-0·97, one-sided p=0·019). Response rate for cabozantinib was 23% versus 4% for sunitinib (two-sided p=0·010). Savolitinib and crizotinib did not improve PFS compared with sunitinib. Grade 3 or 4 adverse events occurred in 31 (69%) of 45 patients receiving sunitinib, 32 (74%) of 43 receiving cabozantinib, ten (37%) of 27 receiving crizotinib, and 11 (39%) of 28 receiving savolitinib; one grade 5 thromboembolic event was recorded in the cabozantinib group. Cabozantinib treatment resulted in significantly longer PFS compared with sunitinib in patients with metastatic PRCC. National Institutes of Health and National Cancer Institute.

Concizumab prophylaxis in people with haemophilia A or haemophilia B without inhibitors (explorer8): a prospective, multicentre, open-label, randomised, phase 3a trial.

Concizumab is an anti-tissue factor pathway inhibitor monoclonal antibody in development as a once-daily, subcutaneous prophylaxis for patients with haemophilia A or haemophilia B with or without inhibitors. We aimed to assess the efficacy and safety of concizumab in patients with haemophilia A or B without inhibitors. Here we report the results from the confirmatory analysis cutoff. This prospective, multicentre, open-label, randomised, phase 3a trial (explorer8) was conducted at 69 investigational sites in 31 countries. Eligible patients were male, aged 12 years or older, and had congenital severe haemophilia A or moderate or severe haemophilia B without inhibitors and with documented treatment with clotting factor concentrate in the 24 weeks before screening. The trial was paused because of non-fatal thromboembolic events in three patients (two from this trial [explorer8] and one from a related trial in haemophilia with inhibitors [explorer7; NCT04083781]) and restarted with mitigation measures, including a revised dosing regimen of subcutaneous concizumab at 1·0 mg/kg loading dose on day 1 and subsequent daily doses of 0·20 mg/kg from day 2, with options to decrease to 0·15 mg/kg, stay on 0·20 mg/kg, or increase to 0·25 mg/kg on the basis of concizumab plasma concentration measured after 4 weeks on concizumab. Patients recruited after treatment restart were randomly assigned 1:2 using an interactive web response system to receive no prophylaxis and continue on-demand clotting factor (group 1) or concizumab prophylaxis (group 2). The primary endpoints were the number of treated spontaneous and traumatic bleeding episodes for patients with haemophilia A and haemophilia B separately, assessed at the confirmatory analysis cutoff in randomly assigned patients. Analyses were by intention-to-treat. There were two additional groups containing non-randomly-assigned patients: group 3 contained patients who entered the trial before the trial pause and were receiving concizumab in the phase 2 trial (explorer5; NCT03196297), and group 4 contained patients who received previous clotting factor concentrate prophylaxis or on-demand treatment in the non-interventional trial (explorer6; NCT03741881), patients randomly assigned to groups 1 or 2 before the treatment pause, and patients from explorer5 enrolled after the treatment pause. The safety analysis set contained all patients who received concizumab. Superiority of concizumab over no prophylaxis was established if the two-sided 95% CI of the treatment ratio was less than 1 for haemophilia A and for haemophilia B. This trial is registered with ClinicalTrials.gov, NCT04082429, and its extension part is ongoing. Patients were recruited between Nov 13, 2019 and Nov 30, 2021; the cutoff date for the analyses presented was July 12, 2022. 173 patients were screened, of whom 148 (86%) were randomly assigned or allocated to the four groups in the study after trial restart on Sept 30, 2020 (nine with haemophilia A and 12 with haemophilia B in group 1; 18 with haemophilia A and 24 with haemophilia B in group 2; nine with haemophilia A in group 3; and 46 with haemophilia A and 30 with haemophilia B in group 4). The estimated mean annualised bleeding rate ratio for treated spontaneous and traumatic bleeding episodes during concizumab prophylaxis versus no prophylaxis was 0·14 (95% CI 0·07-0·29; p<0·0001) for patients with haemophilia A and 0·21 (0·10-0·45; p<0·0001) for patients with haemophilia B. The most frequent adverse events in patients who received concizumab were SARS-CoV-2 infection (19 [13%] of 151 patients), an increase in fibrin D-dimers (12 [8%] patients), and upper respiratory tract infection (ten [7%] patients). There was one fatal adverse event possibly related to treatment (intra-abdominal haemorrhage in a patient from group 4 with haemophilia A with a long-standing history of hypertension). No thromboembolic events were reported between the trial restart and confirmatory analysis cutoff. Concizumab was effective in reducing the bleeding rate compared with no prophylaxis and was considered safe in patients with haemophilia A or B without inhibitors. The results of this trial suggest that concizumab has the potential to be one of the first subcutaneous treatment options for patients with haemophilia B without inhibitors. Novo Nordisk.

Primary lung tumour stereotactic body radiotherapy followed by concurrent mediastinal chemoradiotherapy and adjuvant immunotherapy for locally advanced non-small-cell lung cancer: a multicentre, single-arm, phase 2 trial.

Patients with locally advanced non-small-cell lung cancer (NSCLC) who undergo concurrent chemotherapy and radiotherapy often experience synergistic toxicity, and local regional control rates remain poor. We assessed the activity and safety outcomes of primary tumour stereotactic body radiotherapy (SBRT) followed by conventional chemoradiotherapy to the lymph nodes and consolidation immunotherapy in patients with unresectable locally advanced NSCLC. In this multicentre, single-arm, phase 2 trial, patients aged 18 years and older were enrolled at eight regional cancer centres in North Carolina and South Carolina, USA. Patients were eligible if they had stage II-III, unresectable, locally advanced NSCLC (any histology), with peripheral or central primary tumours that were 7 cm or smaller, excluding central tumours within 2 cm of involved nodal disease, and an Eastern Cooperative Oncology Group performance status of 0-2. Patients who had previously received systemic therapy or radiotherapy were excluded. Participants received SBRT to the primary tumour (50-54 Gy in three to five fractions) followed by standard radiotherapy (planned up to 60 Gy in 30 2 Gy fractions) to the involved lymph nodes with concurrent platinum doublet chemotherapy (either paclitaxel 50 mg/m2 intravenously plus carboplatin area under the curve 2 mg/mL per min every 7 days for a total of six 1-week cycles or etoposide 50 mg/m2 intravenously on days 1-5 and days 29-33 plus cisplatin 50 mg/m2 intravenously on days 1, 8, 29, and 36 for two cycles of 4 weeks). An amendment to the protocol (Dec 11, 2017) permitted the administration of consolidation durvalumab at the discretion of the treating investigator. An additional protocol amendment on Jan 13, 2021, directed patients without disease progression after chemoradiotherapy to receive consolidation durvalumab (10 mg/kg intravenously on day 1 and day 15 of a 4-week cycle for up to 12 cycles or 1500 mg intravenously on day 1 of a 4-week cycle for up to 12 cycles). The primary endpoint was 1-year progression-free survival (per Response Evaluation Criteria in Solid Tumours version 1.1), assessed in all participants who received at least one fraction of SBRT and had radiological follow-up data up to 1 year. A 1-year progression-free survival rate of greater than 60% was required to reject the null hypothesis and show significant improvement in 1-year progression-free survival. One-sided exact binomial tests were used to compare the primary endpoint versus the historical control 1-year progression-free survival rate used to determine the sample size. Safety was assessed in all patients who received at least one fraction of SBRT. This study is registered with ClinicalTrials.gov, NCT03141359, and is closed to accrual. Between May 11, 2017, and June 27, 2022, 61 patients were enrolled and received at least one dose of fractionated SBRT, of whom 59 were evaluable for the primary endpoint. Median age was 67 years (IQR 61-72), 28 (46%) of 61 were female, 33 (54%) were male, 51 (84%) were White, seven (11%) were Black, and three (5%) were of other or unknown race. Of the 61 patients enrolled, 47 received at least one dose of consolidation durvalumab. As of data cutoff (July 12, 2023), median follow-up was 29·5 months (IQR 14·9-47·1). 1-year progression-free survival was 62·7% (90% CI 51·2-73·2; one-sided p=0·39, compared with the historical control rate), with 37 of 59 evaluable participants progression free and alive 1 year after enrolment (n=14 progressed, n=8 died). The most common grade 3-4 treatment-related adverse events were decreased neutrophil count (nine [15%] of 61 patients), decreased white blood cell count (five [8%]), and anaemia (four [7%]). Treatment-related serious adverse events occurred in 11 (18%) of 61 patients, which included lung infection (three [5%]), pneumonitis (two [3%]), decreased neutrophil count (two [3%]), febrile neutropenia (two [3%]), and dyspnoea, hypoxia, respiratory failure, sinus tachycardia, bronchial infection, and acute kidney injury (each in one [2%] patient). Treatment-related deaths occurred in four (7%) of 61 patients (one each of respiratory failure, respiratory failure and dyspnoea, lung infection, and pneumonitis). Although this study did not meet the primary endpoint, activity and safety profiles of primary lung tumour SBRT followed by concurrent mediastinal chemoradiotherapy were favourable compared with other modern trials treating locally advanced NSCLC with chemoradiotherapy. These findings serve as the basis for the ongoing randomised phase 3 study NRG Oncology LU008 (NCT05624996). AstraZeneca and Atrium Health Levine Cancer Institute.

Efficacy and safety of filgotinib as induction and maintenance therapy for Crohn's disease (DIVERSITY): a phase 3, double-blind, randomised, placebo-controlled trial.

There is a need for efficacious therapies for patients with Crohn's disease that are better tolerated and more durable than available treatments. We aimed to evaluate the efficacy and safety of filgotinib, an oral Janus kinase 1 preferential inhibitor, for treating Crohn's disease. This phase 3, double-blind, randomised, placebo-controlled trial was conducted in 371 centres in 39 countries. Eligible patients were aged 18-75 years with moderately to severely active Crohn's disease for at least 3 months before enrolment. Patients were enrolled into one of two induction studies on the basis of their experience with biological agents (induction study A included biologic-naive and later biologic-experienced patients and induction study B included biologic-experienced patients). In both induction studies, patients were randomly assigned (1:1:1), using an interactive web response system, to receive oral filgotinib 200 mg, filgotinib 100 mg, or placebo once daily for 11 weeks. Patients who received filgotinib and had two-item patient-reported outcome (PRO2) clinical remission or an endoscopic response at week 10 were re-randomised (2:1) to receive their induction dose or placebo orally, once daily to the end of week 58 in the maintenance study. Co-primary endpoints were PRO2 clinical remission and an endoscopic response at week 10 (induction studies) and week 58 (maintenance study). PRO2 clinical remission was defined as an abdominal pain subscore of not more than 1 and a liquid or very soft stool frequency subscore of not more than 3 (from eDiary data) and endoscopic response was defined as a reduction of at least 50% in Simple Endoscopic Score for Crohn's disease from induction baseline (from central reading of endoscopy). For the induction studies, efficacy was assessed in all randomly assigned patients who received at least one dose of study drug. For the maintenance study, efficacy was assessed in all patients from either filgotinib treatment group in the induction studies who reached PRO2 clinical remission or an endoscopic response at week 10, and who were re-randomised and received at least one dose of study drug in the maintenance study. Patients who received placebo throughout the induction and maintenance studies were not included in the full analysis set for the maintenance study. Safety was assessed in all patients who received at least one dose of study drug. This trial is complete and is registered with ClinicalTrials.gov, NCT02914561. Between Oct 31, 2016, and Nov 11, 2022, 2634 patients were screened, of whom 1372 were enrolled (induction study A: n=707, induction study B: n=665, and maintenance study: n=481). There were 346 (49%) women and 358 (51%) men in induction study A, 356 (54%) women and 303 (46%) men in induction study B, and 242 women (51%) and 236 men (49%) in the maintenance study. Significantly more patients had PRO2 clinical remission at week 10 with filgotinib 200 mg than with placebo in induction study B (29·7% vs 17·9%, difference 11·9%; 95% CI 3·7 to 20·2, p=0·0039) but not induction study A (32·9% vs 25·7%, 6·9%; -1·4 to 15·2, p=0·0963); there was no significant difference for endoscopic response (induction study A: 23·9% vs 18·1%, difference 5·5%; 95% CI -2·0 to 12·9, p=0·1365; induction study B: 11·9% vs 11·4%, 0·1%; -6·5 to 6·6, p=0·9797). At week 58, both co-primary endpoints were reported in greater proportions of patients who received filgotinib 200 mg than in those who received placebo (PRO2 clinical remission: 43·8% vs 26·4%, difference 16·8%; 95% CI 2·0 to 31·6, p=0·0382; endoscopic response: 30·4% vs 9·4%, difference 20·6%; 95% CI 8·2 to 33·1, p=0·0038). Co-primary endpoints were not met for filgotinib 100 mg in any study. In the induction studies, the most frequently reported treatment-emergent adverse events (TEAEs; ≥5% of patients in any group) were abdominal pain; arthralgia; an exacerbation, flare, or worsening of Crohn's disease; headache; nasopharyngitis; nausea; and pyrexia. In the maintenance study, the most frequently reported TEAEs (≥5% of patients in any filgotinib or associated placebo group) were those reported in the induction studies (except for headache) and abdominal distension, upper abdominal pain, anaemia, and flatulence. Serious TEAEs were reported in 49 patients in induction study A (18 [8%]) of 222 patients in the filgotinib 200 mg group, 16 [7%] of 245 patients in the filgotinib 100 mg group, and 15 [6%] of 237 patients in the placebo group), 81 patients in induction study B (19 [9%] of 202 patients in the filgotinib 200 mg group, 36 [16%] of 228 patients in the filgotinib 100 mg group, and 26 [11%] of 229 patients in the placebo group), and 49 patients in the maintenance study (13 [11%] of 118 patients in the filgotinib 200 mg-filgotinib 200 mg group, five [9%] of 56 patients in the filgotinib 200 mg-placebo group, 14 [13%] of 104 patients in the filgotinib 100 mg-filgotinib 100 mg group, three [5%] of 55 patients in the filgotinib 100 mg-placebo group, and 14 [10%] of 145 patients in the placebo-placebo group). No deaths were reported during the induction and maintenance studies. Filgotinib 200 mg did not meet the co-primary endpoints of clinical remission and an endoscopic response at week 10, but did meet the co-primary endpoints at week 58. Filgotinib treatment was well tolerated, and no new safety signals were reported. Galapagos.
