BeiGene Presents Clinical Data on Pamiparib in Chinese Patients with Ovarian Cancers or Triple-Negative Breast Cancer

BeiGene (NASDAQ:BGNE), a commercial-stage biopharmaceutical company focused on developing and commercializing innovative molecularly targeted and immuno-oncology drugs for the treatment of cancer, today announced that preliminary clinical data from an ongoing Phase 1 trial of its investigational PARP inhibitor pamiparib in Chinese patients with locally advanced or metastatic high-grade non-mucinous ovarian cancer (HGOC), including fallopian cancer, or triple-negative breast cancer (TNBC), who had disease progression following at least one line of chemotherapy were presented at the 2018 American Association for Cancer Research (AACR) Annual Meeting, being held in Chicago.

As quoted in the press release:

“In these heavily pre-treated patients with ovarian and breast cancers, the preliminary results support the recommended pamiparib dosing regimen and demonstrated antitumor activity, including partial responses in platinum-resistant or refractory patients with ovarian cancer. We saw no dose-limiting toxicities and found pamiparib to be generally well tolerated among these patients,” said Binghe Xu, M.D., Director of the Department of Medical Oncology, at the Cancer Hospital, Chinese Academy of Medical Sciences in Beijing, China, and the lead author of the poster presentation.

“In China, there are no currently approved PARP inhibitors, yet there are an aggregate of approximately 75,000 new cases of ovarian cancer¹ and triple-negative breast cancer diagnosed each year^1,2, and it is estimated that between 25 and 30 percent of ovarian cancer³ and between 15 and 20⁴ percent of triple-negative breast cancer patients harbor a germline mutation in BRCA1/2 and therefore may benefit from a PARP inhibitor. We look forward to advancing pamiparib’s development in China as well as initiating a global Phase 3 trial,” commented Amy Peterson, M.D., Chief Medical Officer for Immuno-Oncology of BeiGene.
