| Popis: | Background: This study assessed the checkpoint kinase 1 inhibitor prexasertib in patients with extensive-stage small-cell lung cancer (ED-SCLC). Patients and Methods: This was a parallel-cohort phase II study of 105 mg/m2 prexasertib once every 14 days for patients who progressed after no more than two prior therapies and had platinum-sensitive (Cohort 1) or platinum-resistant/platinum-refractory (Cohort 2) disease. The primary endpoint was objective response rate (ORR). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), safety, and pharmacokinetics. Exploratory endpoints included biomarker identification and assessment of an alternative regimen (Cohort 3: 40 mg/m2 days 1-3, 14-day cycle). Results: In Cohort 1 (n = 58), ORR was 5.2%; DCR, 31%; median PFS, 1.41 months (95% confidence interval [CI], 1.31-1.64); and median OS, 5.42 months (95% CI, 3.75-8.51). In Cohort 2 (n = 60), ORR was 0%; DCR, 20%; median PFS, 1.36 months (95% CI, 1.25-1.45); and median OS, 3.15 months (95% CI, 2.27-5.52). The most frequent all-grade, related, treatment-emergent adverse events were decreased neutrophil count (Cohort 1, 69.6%; Cohort 2, 73.3%), decreased platelet count (Cohort 1, 51.8%; Cohort 2, 50.0%), decreased white blood cell count (Cohort 1, 28.6%; Cohort 2, 40.0%), and anemia (Cohort 1, 39.3%; Cohort 2, 28.3%). Eleven patients (19.6%) in Cohort 1 and one patient (1.7%) in Cohort 2 experienced grade ?3 febrile neutropenia. Prexasertib pharmacokinetics were consistent with prior studies. Cohort 3 outcomes were similar to those of Cohorts 1 and 2. No actionable biomarkers were identified. Conclusion: Prexasertib did not demonstrate activity to warrant future development as monotherapy in ED-SCLC. © 2021 The Authors Boehringer Ingelheim; Amgen; Bristol-Myers Squibb; Eli Lilly and Company; Pfizer; Astellas Pharma US; AstraZeneca; Merck; Novartis; Roche; AbbVie; University of Michigan; Takeda Pharmaceuticals U.S.A.; Merck Sharp and Dohme; PTC Therapeutics; TG Therapeutics; NIHR Biomedical Research Centre, Royal Marsden NHS Foundation Trust/Institute of Cancer Research; Bayer Fund; National Institute for Health Research; European Commission; Daiichi-Sankyo; Oryzon Genomics; Otsuka Pharmaceutical; UCLH Biomedical Research Centre We thank the patients who participated in this trial and the study coordinators, nurses, nurse practitioners, clinical research assistants, and doctors who assisted with the research.
