A Phase III Randomized Controlled Clinical Study Comparing BL-B01D1 With Treatment of Physician's Choice in Patients With Locally Advanced or Metastatic Biliary Tract Cancer After Failure of Platinum-based Chemotherapy(PANKU-BTC01)
This trial is a registrational Phase III, randomized, open-label, multicenter study to evaluate the efficacy and safety of BL-B01D1 compared with the investigator's choice of protocol in patients with locally advanced or metastatic biliary tract cancer who have failed prior platinum-based chemotherapy.
