Brief Summary

The primary trial objective is to determine the efficacy of KPT-330 (selinexor) in participants with advanced or metastatic gynaecological cancers by disease control rate (complete response (CR) or partial response (PR) or stable disease (SD) for at least 12 weeks, assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

Detailed Description

Two-stage Phase 2 study in 3 separate gynecological cancer cohorts, with an additional set of participants in the ovarian cohort randomized into 2 different treatment regimens. The study is divided between a Primary Treatment Phase and a Maintenance Phase with each phase supported by a separate database.

Part 1 - Three parallel cohorts of participants with ovarian (Cohort A), endometrial (Cohort B), or cervical (Cohort C) carcinoma were enrolled.

Part 2 - Based on the observed tolerability and efficacy profile in the ongoing ovarian cohort (Cohort A), 2 additional treatment schedules will be explored to optimize the dosing schedule in a participant population with ovarian carcinoma.

Conditions

Ovarian Carcinoma; Endometrial Carcinoma; Cervical Carcinoma

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Part 1: Cohort A-Ovarian carcinoma: Selinexor up to 60 mg/m^2 BIW

Participants with ovarian carcinoma who were platinum refractory or platinum resistant and had received at least one line of chemotherapy for relapsed disease received a dose of 50 milligram per meter square (mg/m\^2) of selinexor oral tablets twice weekly (BIW) (doses at least 36 hours apart) with light meal and 120 milliliters (mL) of water in a 4-week treatment cycles. After 12 weeks of treatment, a dose of 60 mg/m\^2 of selinexor oral tablets BIW were administrated if the participants had no major toxicity. During dose reduction, participants received a minimum dose of 35 mg/m\^2 once weekly (QW). This treatment continued until progression of disease (PD) or unacceptable toxicity or any discontinuation criteria or withdrawal of consent by the participant, or non-compliance by the participant with protocol requirements.
