May 27, 2021 updated by: Chia Tai Tianqing Pharmaceutical Group Co., Ltd.

A Open-label, Multicenter Phase II Study of TQ-B3525 Tablets in Subjects With PIK3CA and/or PIK3R1/2 Gene-altered Recurrent/Metastatic Advanced Gynecologic Tumors

This is a study to evaluate the efficacy and safety of TQ-B3525 in subjects with recurrent / metastatic advanced endometrial cancer, cervical cancer and ovarian cancer with PIK3CA and / or PIK3R1 / 2 gene-altered (mutation or amplification). Endometrial cancer, cervical cancer and ovarian cancer are divided into three cohorts, each cohort administrated TQ-B3525 tablet orally once a day.
