We hypothesized that prexasertib would be active in HGSOC without HR dysfunction; this was in part due to the acknowledged upregulation/amplification of cyclins E and D.22 Examination of biopsies taken prior to initiation of therapy showed two thirds of women with CCNE1-overexpressing tumours had clinical benefit. with ClinicalTrials.gov (“type”:”clinical-trial”,”attrs”:”text”:”NCT02203513″,”term_id”:”NCT02203513″NCT02203513) and enrolling the patients of mutation cohort. Findings Between January 2015 and November 2016, 28 women (median age 64-year-old [IQR 58C695], with median 5 prior systemic therapies [IQR 25C5]) were enrolled and received at least one dose of prexasertib. Eight of 24 evaluable patients experienced a partial response (PR; 33%, 95% CI: 16C55) and 50% experienced a GCIG CA125 response. The RR in the intention-to-treat populace was 29% (8/28, 95% CI: 13C49). The common (>10%) grade 3 or 4 4 treatment-emergent adverse events were neutropenia (26 [93%] patients), thrombocytopenia (seven [25%] patients), and anaemia (three [11%] patients). Grade 4 neutropenia occurred in 22 (79%) patients after the first dose and was transient 7 days (median 6 days [IQR 4C8]) without growth factor support; the incidence of febrile neutropenia was 7% (2/28). Interpretation We demonstrate clinical activity of prexasertib in wild-type HGSOC, especially patients with platinum-resistant or refractory ovarian malignancy. These results warrant further development for this unmet patient need. Funding Intramural Research Program of the National Institutes of Health, National Cancer Institute, Center for Cancer Research, USA. wild-type, CCNE1 amplification and/or overexpression INTRODUCTION High-grade serous ovarian carcinoma (HGSOC) is the most lethal gynecologic malignancy in the United States.1 The majority of patients with HGSOC experience relapse at some point in time despite responses to initial cytoreductive surgery and platinum-based chemotherapy, then ultimately develop platinum resistance. 2 The prognosis for these patients remains poor and novel therapeutic strategies are needed.2 HGSOC is characterized by a high frequency of mutation-associated HGSOC and in mutation. METHODS Study design and participants This study was designed as a signal-seeking study with three independent cohorts, triple negative breast cancer, germline wild-type ovarian cancer. This report describes the wild-type ovarian cancer cohort. Eligible patients were age 18 years and had recurrent sporadic high-grade serous or high-grade endometrioid ovarian carcinoma, either absence of deleterious germline mutation upon testing or a negative family history of hereditary breast ovarian cancer syndrome (appendix p 5). Other histologic types of ovarian cancer were not eligible. Patients must have had measurable disease by Response Evaluation Criteria In Solid Tumors (RECIST) v11 and disease amenable to safe percutaneous biopsy (appendix p 1). There were no restrictions on the number of prior treatment regimens. Other inclusion criteria included ISG20 radiological progression after one or more lines of therapy, an Eastern Cooperative Oncology Group performance status 0C2, and adequate organ and marrow function, defined as hemoglobin 100 g/L, absolute neutrophil count 15 109 per L, platelet count 100 109 per L, total bilirubin 15 the upper limit of normal (ULN), alanine aminotransferase and aspartate aminotransferase 3 ULN, and serum creatinine 15 ULN or measured glomerular filtration rate 45 mL/min per 173 m2 (appendix p 5). Study exclusion criteria included concurrent anticancer therapy or any investigational anticancer therapy 4 weeks before first doses of prexasertib, prior prexasertib or other cell cycle checkpoint kinase inhibitors and central nervous system metastases within 1 year of enrollment (appendix p 1). All patients provided written informed consent before enrollment. The trial was approved by the Institutional Review Board of the Center for Cancer Research, National Cancer Institute, USA. Procedures Eligible patients received intravenous prexasertib monotherapy at 105 mg/m2 every two weeks in 4-week cycles. Blood counts were repeated on cycle 1 day 8 to check absolute neutrophil count nadir. 11 Laboratory assessments (including haematology, fasting serum chemistry, and urinalysis) and electrocardiogram were done within 24 hours before each study drug administration during cycle 1 then every 4-week cycle. Clinical response was assessed by the investigator every two cycles by computed tomography (CT) imaging using RECISTv11 criteria. Serum CA125 response was investigated every cycle as a post-hoc exploratory end point and was defined as a 50% reduction during treatment with confirmation after 4 weeks according to GCIG criteria.12 Patients were evaluated for toxicity per Common Terminology Criteria for Adverse Events version (CTCAE) v40. Events of temporary ( 7 days) neutropenia without fever (grade three or four 4) didn’t require dose decrease or discontinuation of treatment. Quality three or four 4 thrombocytopenia > seven days or any thrombocytopenia needing platelet transfusion for bleeding led to dose decrease to 80 mg/m2 every fourteen days. Research treatment was.The protocol-defined major objective was met, with 33% of individuals achieving a PR. position of 0 or one or two 2, and sufficient haematological, renal, and hepatic function. Individuals received intravenous prexasertib 105mg/m2 once every 14 days until disease development, undesirable toxicity or individual drawback of consent. The principal endpoint was investigator-assessed tumour response per process predicated on Response Evaluation Requirements in Solid Tumors, edition 11 in evaluable individuals.

Eight of 24 evaluable individuals got a incomplete response (PR; 33%, 95% CI: 16C55) and 50% got a GCIG CA125 response. The RR in the intention-to-treat human population was 29% (8/28, 95% CI: 13C49).
