Phase II study of ceritinib in alectinib-pretreated patients with anaplastic lymphoma kinase-rearranged metastatic non-small-cell lung cancer in Japan: ASCEND-9.

ABSTRACT: Clinical experience of ceritinib in patients who progressed on alectinib is limited. In this prospective phase II study, we evaluated the activity of ceritinib in alectinib-pretreated patients with anaplastic lymphoma kinase (ALK)-rearranged metastatic (stage IIIB/IV) non-small-cell lung cancer (NSCLC) in Japan. All patients were required to have ?1 measurable lesion per RECIST, 1.1, and a World Health Organization Performance Status (WHO PS) of 0-1. Prior crizotinib and/or up to 1 chemotherapy regimen was allowed. Primary endpoint was investigator-assessed overall response rate (ORR) per RECIST 1.1. Ceritinib was given at a dose of 750 mg/day fasted. A total of 20 patients were enrolled from August 2015 to March 2017. All patients received prior alectinib (100%), 13 (65.0%) patients received prior platinum-based chemotherapy, and 4 (20%) patients received prior crizotinib. Median duration of exposure and the follow-up time with ceritinib were 3.7 months (range: 0.4-15.1) and 11.6 months (range: 4.8-23.0), respectively. Investigator-assessed ORR was 25% (95% CI: 8.7-49.1). Key secondary endpoints, all investigator assessed, included disease control rate (70.0%; 95% CI: 45.7-88.1), time to response (median, 1.8 months; range: 1.8-2.0), and duration of response (median, 6.3 months; 95% CI: 3.5-9.2). Median progression-free survival was 3.7 months (95% CI: 1.9-5.3). The most common adverse events reported were diarrhea (85.0%), nausea (80.0%), and vomiting (65.0%). Based on our findings, ceritinib could be considered as one of the treatment options for patients with ALK-positive NSCLC who progressed on alectinib. (Trial registration no. NCT02450903).

Project description:Background:This is the first trial to directly compare efficacy and safety of alectinib versus standard chemotherapy in advanced/metastatic anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC) patients who have progressed on, or were intolerant to, crizotinib. Patients and methods:ALUR (MO29750; NCT02604342) was a randomized, multicenter, open-label, phase III trial of alectinib versus chemotherapy in advanced/metastatic ALK-positive NSCLC patients previously treated with platinum-based doublet chemotherapy and crizotinib. Patients were randomized 2 : 1 to receive alectinib 600?mg twice daily or chemotherapy (pemetrexed 500?mg/m2 or docetaxel 75?mg/m2, both every 3?weeks) until disease progression, death, or withdrawal. Primary end point was investigator-assessed progression-free survival (PFS). Results:Altogether, 107 patients were randomized (alectinib, n?=?72; chemotherapy, n?=?35) in 13 countries across Europe and Asia. Median investigator-assessed PFS was 9.6?months [95% confidence interval (CI): 6.9-12.2] with alectinib and 1.4?months (95% CI: 1.3-1.6) with chemotherapy [hazard ratio (HR) 0.15 (95% CI: 0.08-0.29); P?<?0.001]. Independent Review Committee-assessed PFS was also significantly longer with alectinib [HR 0.32 (95% CI: 0.17-0.59); median PFS was 7.1?months (95% CI: 6.3-10.8) with alectinib and 1.6?months (95% CI: 1.3-4.1) with chemotherapy]. In patients with measurable baseline central nervous system (CNS) disease (alectinib, n?=?24; chemotherapy, n?=?16), CNS objective response rate was significantly higher with alectinib (54.2%) versus chemotherapy (0%; P?<?0.001). Grade ?3 adverse events were more common with chemotherapy (41.2%) than alectinib (27.1%). Incidence of AEs leading to study-drug discontinuation was lower with alectinib (5.7%) than chemotherapy (8.8%), despite alectinib treatment duration being longer (20.1?weeks versus 6.0?weeks). Conclusion:Alectinib significantly improved systemic and CNS efficacy versus chemotherapy for crizotinib-pretreated ALK-positive NSCLC patients, with a favorable safety profile. Trial registration:ClinicalTrials.gov NCT02604342; Roche study MO29750.
