Overview
Brief Summary
There will be two phases to this study. The lead-in phase will evaluate the safety, pharmacokinetics, and define the maximum tolerated dose (MTD) of momelotinib (MMB) combined with nab-paclitaxel and gemcitabine (nab-P + G) in adults with previously untreated metastatic pancreatic ductal adenocarcinoma. The randomized treatment phase will evaluate the efficacy, safety, and tolerability of nab-P + G with either MMB administered at the MTD or placebo in adults with previously untreated metastatic pancreatic ductal adenocarcinoma. Participants will continue study treatment until disease progression, unacceptable toxicity, consent withdrawal, or participant's refusal of treatment. Following treatment, participants will be followed for safety for 30 days and for survival approximately every 3 months for up to 3 years.

Outcomes
Primary Outcomes
Lead-In Phase: Percentage of Participants Experiencing Treatment-Emergent Dose Limiting Toxicity (DLT) Adverse Events
Time Frame: Up to 28 Days
Dose limiting toxicities were based on the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Dose limiting toxicities referred to toxicities experienced during the first 28 days (Cycle 1) of treatment that were judged to be clinically significant and related to study treatment. No statistical analysis was planned or performed for this endpoint.
Randomized Treatment Phase: Overall Survival (OS)
Time Frame: Baseline up to the Date of Death or Censoring, up to 3 years
Overall survival was defined as the time interval from first dose date of MMB to death from any cause
Secondary Outcomes
- Lead-In Phase: Progression-Free Survival (PFS)(Baseline up to the Date of Event or Censoring, up to 3 years)
- Lead-In Phase: Overall Survival (OS)(Baseline up to the Date of Death or Censoring, up to 3 years)
- Lead-In Phase: Overall Response Rate (ORR)(Baseline up to the Last Tumor Assessment Date, up to 3 years)
- Randomized Treatment Phase: Progression-Free Survival (PFS)(Baseline up to the Date of Event or Censoring, up to 3 years)
- Randomized Treatment Phase: Overall Response Rate(Baseline up to the Last Tumor Assessment Date, up to 3 years)
