Compare PFS in patients treated with napabucasin plus weekly nab-paclitaxel with gemcitabine vs. weekly nab-paclitaxel with gemcitabine alone; assess ORR – de�ned as patients with a documented (CR + PR) based on RECIST 1.1; assess quality of life, as assessed by the EORTC-QLQ-C30, in the general study population

Primary objectives/rationale

Study design and treatment including planned sample size, planned study period and study procedures

Determine whether the addition of orally administered napabucasin to weekly nab-paclitaxel and gemcitabine improves OS , compared to weekly nab-paclitaxel and gemcitabine alone in patients with mPDAC who have not received prior systemic chemotherapy in the metastatic setting

Global Open-label

Multicenter Phase III

Randomized patients: 1132

Randomized 1:1

?1132

Patients will be randomized in a 1:1 ratio to receive either twice daily napabucasin plus weekly nab-paclitaxel with gemcitabine (Arm A) or weekly nab-paclitaxel with gemcitabine (arm B) in 28-day cycles

Age ≥18 years

Outcome measures/end points

Secondary end points: PFS; ORR per RECIST; and QoL

Key eligibility criteria

Study period: December 15th 2016 – December 2020

In each arm, nab-paclitaxel at 125 mg/m2 will be administered, followed by gemcitabine 1000 mg/m2, on days 1, 8, and 15 of a 28-day cycle. In arm A, napabucasin will be given orally, twice-daily, at 240 mg (480 mg total daily dose). For cycle 1, napabucasin will be started 2–5 days prior to the �rst nab-paclitaxel with gemcitabine infusion.

Histological or cytological con�rmationof advanced PDAC that is metastatic

Patients must not have received prior cytotoxic chemotherapy or any investigational agents for treatment of mPDAC except in the case where either prior �uoropyrimidine or gemcitabine was used as a radiation sensitizer in the adjuvant setting with last dose administered > 6 months prior to randomization.

ECOG performance status score of 0 or 1 at randomization

Patients must have had adequate liver, renal and bone marrow function
