Eligibility Criteria
Inclusion Criteria:
- Patient has definitive histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas. Patients with islet cell or neuroendocrine neoplasms are excluded.
- Initial diagnosis of metastatic disease must have occurred ≤8 weeks prior to entry in the study.
- Patient has one or more metastatic tumors measurable per RECIST 1.1 by CT scan ≤4 weeks prior to entry into the study
- Male or non-pregnant and non-lactating female, and ≥18 years of age.
- Patients must have received no previous radiotherapy, surgery, chemotherapy or investigational therapy for the treatment of metastatic disease.
- Prior treatment with gemcitabine and/or nab-paclitaxel in the adjuvant setting is allowed, provided at least 6 months have elapsed since completion of the last dose and no lingering toxicities are present.
- Patients cannot have received any other immunomodulatory therapies (including vaccines) as treatment for this or any other cancer.
- Patient has a Karnofsky performance status (KPS) ≥ 70.
- Patients should be asymptomatic for jaundice prior to Day 1.
Exclusion Criteria:
- Patients may not be receiving (or received prior to enrollment) any other investigational agents for metastatic disease.
- Patient has known brain metastases,
- Patient has only locally advanced disease.
- Lymph node only metastases even if considered M1 disease by official staging criteria.
- History of malignancy in the last 3 years. Patients with prior history of in situ cancer or basal or squamous cell skin cancer are eligible. Patients with other malignancies are eligible if they were cured by surgery alone or surgery plus radiotherapy and have been continuously disease-free for at least 3 years.
- Patients with any active autoimmune disease
- Patient has undergone major surgery, other than diagnostic surgery (ie, surgery done to obtain a biopsy for diagnosis without removal of an organ), within 4 weeks prior to Day 1 of treatment in this study.

Arms of the Study
Arm 1
Experimental
Indoximod and Gemcitabine + Nab-paclitaxel
Phase 1 portion: Participants to receive indoximod (600mg, 100mg, or 1200mg according to their assigned dose cohort) PO BID for 28 days concurrently with IV Nab-paclitaxel 125 mg/m^2 followed by gemcitabine 1000 mg/m^2 weekly for 3 weeks with one week rest. Each cycle is 28 days. Patients will continue until they experience disease progression or significant toxicity. Phase 2 portion: Once a RP2D is determined, treatment will commence with oral indoximod concurrent with the first backbone chemotherapy cycle.Patients will receive gemcitabine plus nab-paclitaxel on a standard 4 week cycle schedule. Oral indoximod will continue throughout.
