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: United States (US) vs China , duration of the platinum free interval (PFI): 1 3 months vs >3-6 months and number of prior platinum based therapy treatments (1/2 versus 3 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 PFS follow up). Patients will be tested at baseline for phosphoinositide 3 kinase (PI3K)/AKT/PTEN pathway alterations, BRCA1/2 mutations 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.

The archival tumor biopsy sample collected less than 1 year is preferred. If no archival tumor sample is available, fresh biopsy will be recommended. For patients who cannot provide a tumor sample or cannot accept fresh tumor biopsy, the Sponsor should be consulted about their qualification to enter this study.
  3. Patients must have histologically or cytologically confirmed high grade serous OC, endometroid OC, or ovarian clear cell carcinoma (including fallopian tube and primary peritoneal cancers). Carcinosarcoma, sarcoma, mucinous OC, or low-grade serous histologies must be excluded.

  13. Toxicities of prior therapy (except alopecia) should have been resolved to less than or equal to grade 1 as per NCI-CTCAE v5.0.
  14. Patients must be able to tolerate oral medications and not have any GI illnesses that would preclude absorption of afuresertib.
  15. Patient must have a life expectancy of greater than 6 months.
  16. Must have at least one lesion that meets the definition of measurable disease by RECIST 1.1 criteria (Appendix 3).
  17. Patients of childbearing potential must agree to use adequate contraception (barrier method of birth control or abstinence) prior to study entry and for the duration of study participation. If a woman becomes pregnant or suspects she is pregnant while participating in this study, she should inform her treating physician immediately.

  9. Any condition for which, in the opinion of the investigator, participation would not be in the best interest of the patient (eg, compromise well-being) or that could prevent, limit, or confound the protocol-specified assessments.
  10. Any medical contraindication to the use of paclitaxel.
  11. Prior radiotherapy ≤ 15 days prior to Study Day 1, with the exception of a single fraction of radiotherapy for the purposes of palliation, which is permitted.
