A Study of BL-B01D1 Plus an Anti-PD-1 Antibody Versus Nab-paclitaxel Plus an Anti-PD-1 Antibody in Patients With Previously Untreated, Locally Advanced, Inoperable or Metastatic Triple-Negative Breast Cancer Whose Tumors Express PD-L1 (PANKU-Breast04)

28. september 2026 opdateret af: Sichuan Baili Pharmaceutical Co., Ltd.

A Phase III Randomized Controlled Clinical Study of BL-B01D1 Plus an Anti-PD-1 Antibody Versus Nab-paclitaxel Plus an Anti-PD-1 Antibody in Patients With Previously Untreated, Locally Advanced, Inoperable or Metastatic Triple-Negative Breast Cancer Whose Tumors Express PD-L1 (PANKU-Breast04)

This trial is a registrational Phase III, randomized, open-label, multicenter study designed to compare the efficacy and safety of BL-B01D1 in combination with a PD-1 monoclonal antibody versus nab-paclitaxel in combination with a PD-1 monoclonal antibody in patients with PD-L1-positive, previously untreated, inoperable locally advanced or recurrent metastatic triple-negative breast cancer.
