Study Description

Brief Summary:

Afuresertib is an AKT inhibitor, a new class of agents under development that may provide physicians with a new clinical option to control platinum resistant ovarian cancer (PROC) progression. Afuresertib plus chemotherapy has demonstrated anti-tumor efficacy and an acceptable safety profile in patients with PROC in a published Phase I/II study. Therefore, the combination of afuresertib plus weekly paclitaxel could represent a clinically meaningful step forward in the clinical management of these difficult-to-treat patients with PROC.

Condition or disease	Intervention/treatment	Phase
Platinum-resistant Ovarian Cancer	Drug: Paclitaxel; Drug: Afuresertib	Phase 2

Detailed Description:

A total of approximately 141 patients with PROC are planned to be enrolled and randomized with a 2:1 ratio in an open label manner to the 2 arms (94 patients in the combination treatment arm and 47 patients in the paclitaxel arm) for efficacy and safety evaluation. The randomization will be stratified by country (the United States vs. China), prior bevacizumab use (yes vs. no), and number of prior platinum based therapy treatments (1-2 vs. 3-5 prior platinum regimens). The study will consist of 3 periods. The first period is the Screening Period (Day -24 to 1) during which patients are screened for eligibility according to the inclusion and exclusion criteria. The second period is a Treatment Evaluation Period with a randomized, open-label, two arm parallel design (from starting study treatment until patients have progressive disease [PD], unacceptable toxicity, death, or withdrawal of consent). The PK study will be applied to both the combination treatment arm and control arm. The third period is a Follow up Period (safety evaluation at 30 days after the last dose of study treatment and OS and/or PFS follow up). Patients will be tested at baseline for phosphoinositide 3 kinase (PI3K)/AKT/PTEN pathway alterations and BRCA1/2 mutations by NGS, and/or level of phospho AKT by IHC; the correlation of the efficacy endpoints and biomarker status will be analyzed retrospectively as an exploratory endpoint.
