The objective of the study is to determine a new combination of drug that improves the outcome in patients with advanced (unresectable or metastatic) BTC. The primary objective of the phase I part of the study is to determine the maximum tolerated dose (MTD) of the combination gemcitabine plus oxaliplatin plus nab-paclitaxel, established in the first cycle of therapy, in order to determine the recommended phase II dose (RP2D). The primary objective of the phase II is to determine activity of GEMOX plus nab-paclitaxel.
