PRIMARY OBJECTIVES:
I. Determine the progression-free survival (PFS) of gemcitabine hydrochloride (gemcitabine), cisplatin, and nab-paclitaxel in advanced, untreated biliary cancers (intrahepatic cholangiocarcinomas, extrahepatic cholangiocarcinomas, and gallbladder cancers).
SECONDARY OBJECTIVES:
I. Determine the response rate (RR) and disease control rate (partial response + complete response + stable disease) of gemcitabine, cisplatin, and nab-paclitaxel in advanced biliary cancers.
II. Determine overall survival (OS) of gemcitabine, cisplatin, and nab-paclitaxel in advanced biliary cancers.
III. Evaluate the toxicity of gemcitabine, cisplatin, and nab-paclitaxel in advanced biliary cancers.
EXPLORATORY OBJECTIVES:
I. Correlate the carbohydrate antigen (CA) 19-9 response (defined as >50% decrease from baseline) with tumor response, PFS and OS.
II. Assess ribonucleotide reductase subunit MI (RRMI), excision repair cross-complementation group 1 (ERCC1) pre-treatment status and correlate with tumor response, PFS and OS on an exploratory basis.
III. Collect optional blood and tissue at the start of treatment and at progression to explore mechanisms of resistance.
OUTLINE:
Patients receive paclitaxel albumin-stabilized nanoparticle formulation intravenously (IV) over 30 minutes, cisplatin IV over 60 minutes, and gemcitabine hydrochloride IV over 30 minutes on days 1 and 8. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 3 months thereafter.
