Study of IMP4297 in Patients With BRCA1/2 Mutation Ovarian Cancer (SABRINA)

A Phase II Study to Evaluate the Efficacy, Safety, and Tolerability of IMP4297 Capsules in Subjects With Germline and/or Systemic BRCA1/2 Mutation Positive Advanced Ovarian Cancer With at Least 2 Prior Lines of Standard Systemic Therapy

A phase II, multi-center, open-label, single-arm, non-randomized study to evaluate the efficacy, safety and tolerability of IMP4297 capsules in subjects with germline and/or systemic BRCA1/2 mutated advanced ovarian cancer in china

Study Overview

• Status: Unknown
• Conditions: Ovarian Cancer
• Intervention / Treatment: Drug: IMP4297

Detailed Description

A total of 100 subjects with germline and/or systemic BRCA1/2 mutated advanced ovarian cancer is planned to be enrolled to observe the efficacy, safety, tolerability and PK profile of IMP4297.

The primary objective is to assess ORR in subjects with germline and/or systemic BRCA1/2 mutated advanced ovarian cancer with at least 2 prior lines of standard systemic therapy treated with IMP4297 capsules by independent imaging according to RECIST v1.1. Subjects will be treated until there is evidence of disease progression or any other discontinuation criterion is met. Best supportive care will be provided to all subjects and will be decided by investigators if there are no other specific restrictions within the protocol.

Four to seven blood samples (approximately 2 mL/sample) are planned to be collected for each enrolled subject for the popPK and/or dose-response evaluation. Sample collection visits are planned on Cycle (C) 1 Day (D) 1, C1D15, C2D1, C3D1 and C4D1. The actual administration time, dose and blood collection time should be accurately recorded.
