Results: As of October 1, 2023, 36 patients (pts) with heavily pretreated (median 5 prior lines) metastatic breast cancer (BC) were treated.

• Promising clinical benefit:
  • 28 pts receiving tinengotinib monotherapy were efficacy evaluable. 11 pts with HR+/HER2- BC achieved overall response rate (ORR) of 45%, clinical benefit rate (CBR, CR+PR+SD ≥ 24 weeks) of 64%, disease control rate (DCR) of 82% and median progression-free survival (mPFS) of 5.68 months. Partial responses were observed in 3 pts with HER2-zero and 2 pts with HER2 low (1+/2+) pts, respectively. One patient has been on the treatment for over 17 months and is still on-going. 17 pts with TNBC had ORR of 24%, CBR of 29%, DCR of 71% and mPFS of 2.73 months. Notably, 5 TNBC patients who were originally diagnosed as HR+/HER2- breast cancer had achieved 3 partial responses and 2 stable diseases.
  • Among 6 pts treated with tinengotinib in combination with nab-paclitaxel, 1 TNBC patient achieved PR and the treatment duration lasted for 6.5 months. 3 patients achieved stable diseases.
