A Trial of YL-13027 in Combination With Gemcitabine and Nab-paclitaxel in Patients With Refractory Metastatic Pancreatic Cancer

Primary Objectives 1. To determine the safety and tolerability of YL-13027 in combination with gemcitabine and nab-paclitaxel in participants with refractory metastatic pancreatic cancer. 2. To determine the objective response rate (ORR) of YL-13027 in combination with gemcitabine and nab-paclitaxel in participants with refractory metastatic pancreatic cancer. Secondary Objectives 1. To evaluate other indicators of the antitumor activity of YL-13027 in combination with gemcitabine and nab-paclitaxel. 2. To evaluate the PK of YL-13027 in combination with gemcitabine and nabpaclitaxel. Exploratory Objectives 1. To evaluate the PD effects of YL-13027 in combination with gemcitabine and nabpaclitaxel. 2. To evaluate biomarkers of response and resistance to YL-13027 in combination with gemcitabine and nab-paclitaxel.
