Primary Outcome Measures:
  • Phase 2 Dosing [ Time Frame: 10 months ]

    Phase 1 component:

    To determine recommended phase 2 dose of indoximod when administered with a standard of care chemotherapy backbone consisting of gemcitabine plus nab-paclitaxel.


  • Regimen Limiting Toxicity [ Time Frame: 10 months ]

    Phase 1 component:

    To identify the regimen limiting toxicity (RLT) for the combination of the immunotherapeutic agent indoximod when administered in combination with standard of care chemotherapy gemcitabine plus nab-paclitaxel in subjects with metastatic adenocarcinoma of the pancreas.

    RLT will be considered as only grade 3 and 4 toxicities that are attributable to the test agent and result in the delay of the administration of the backbone chemotherapy, gemcitabine plus nab-paclitaxel.


  • Overall Survival [ Time Frame: 22 months ]

    Phase 2 component:

    To evaluate efficacy as determined by overall survival (OS) in patients with metastatic adenocarcinoma of the pancreas.



Secondary Outcome Measures:
  • Biomarker Response [ Time Frame: 22 months ]
    A secondary objective is to examine biomarker responses of gemcitabine and nab-paclitaxel with indoximod through the evaluation of serum for biomarkers of IDO activity (kynurenine and tryptophan), before and after initiation of therapy through specimen collection at protocol specified timepoints.

  • Response Rate [ Time Frame: 22 months ]
    To determine the response rate of the combination indoximod with gemcitabine plus nab-paclitaxel. Imaging assessments to be performed at protocol-specified time points and evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1).

  • Time to Progression of Disease [ Time Frame: 22 months ]
    To determine the time to progression with the combination indoximod with gemcitabine plus nab-paclitaxel. Progression will be evaluated in this study using the new international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1).


Estimated Enrollment: 98

Detailed Description:

This is a Phase I/II trial designed to evaluate the combination of the immunotherapeutic agent indoximod and the standard of care chemotherapy gemcitabine plus nab-paclitaxel in subjects with metastatic adenocarcinoma of the pancreas. The phase 1 portion is designed to identify the regimen-limiting toxicity (RLT) and recommended phase 2 dose (RP2D) for the combination. The phase 2 portion of the study will evaluate the potential efficacy of this combination. All subjects will receive the standard 28-day gemcitabine plus nab-paclitaxel regimen. Twice daily oral indoximod will be administered concurrently in continuous 28 day cycles.

In the phase 1 portion, dose escalation of indoximod will begin at 600mg/day and potentially escalate to 1200mg/day. There will be no intra-subject dose escalation. Regimen-limiting toxicity will be considered as those toxicities related to indoximod that significantly limit the administration of the backbone chemotherapy gemcitabine plus nab-paclitaxel. The period for determination of dose-limiting toxicities will be the initial 28 days of treatment. The recommended phase 2 dose will include an assessment of toxicities that occur at later time points.

Once a RP2D is determined, the phase 2 portion of the study will be initiated. In both phase 1 and phase 2, every 2 cycles subjects will have repeat imaging to assess response. Corollary biomarkers will be assessed at the same interval as will PET-CT after the 1st 8 week cycle. Up to 18 patients will be enrolled in the phase 1 portion of the study and 80 patients will be enrolled in the phase 2 portion.

  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patient has definitive histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas. The definitive diagnosis of metastatic pancreatic adenocarcinoma will be made by integrating the histopathological data within the context of the clinical and radiographic data. 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 (or MRI, if patient is allergic to CT contrast media). Patients cannot have nodal metastases alone even if such nodal metastases are formally considered M1 disease
  • Life expectancy of greater than 3 months.
  • Male or non-pregnant and non-lactating female, and ≥18 years of age.
  • If a female patient is of child-bearing potential, as evidenced by regular menstrual periods, she must have a negative serum pregnancy test (β-hCG) documented within 7 days prior to the first administration of study drug.
  • The effects of indoximod on the developing human fetus are unknown. For this reason and because indoximod may affect maternal immune tolerance of the fetus, sexually active women of child-bearing potential must agree to use two forms of contraception (hormonal and barrier method of birth control or abstinence) prior to study entry and for the duration of study participation. Use of contraception or abstinence should continue for a minimum of 1 month after completion of the study. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should discontinue the study drug and inform her treating physician immediately. Also men should be discouraged from fathering children while on treatment.
  • 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 adequate biological parameters as demonstrated by the following blood counts at Baseline (obtained ≤14 days prior to treatment initiation):
  • Absolute neutrophil count (ANC) ≥1.5 × 10^9/L
  • Platelet count ≥75,000/mm3 (75 × 10^9/L)
  • Hemoglobin (Hgb) ≥9 g/dL.
  • Patient has the following blood chemistry levels at Baseline (obtained ≤14 days prior to randomization):
  • AST (SGOT), ALT (SGPT) ≤2.5 × upper limit of normal range (ULN), unless liver metastases are clearly present, then ≤5 × ULN is allowed
  • Total bilirubin ≤ULN, patients with known Gilbert's syndrome allowed up to 3x ULN.
  • Serum creatinine within normal limits or calculated clearance ≥60 mL/min/1.73 m^2 for patients with serum creatinine levels above or below the institutional normal value
  • Patient has acceptable coagulation studies (obtained ≤14 days prior to randomization) as demonstrated by prothrombin time (PT) and partial thromboplastin time (PTT) within normal limits (±15%). If the patient is on coumadin we suggest switching the patient to a low molecular weight heparin product including enoxaparin (Lovenox) and fondiparinux (Arixtra), but if not feasible then INR must be ≤ 3.
  • Patient has no clinically significant abnormalities in urinalysis results (obtained ≤14 days prior to randomization).
  • Patient has a Karnofsky performance status (KPS) ≥ 70.
  • Patients should be asymptomatic for jaundice prior to Day 1.
  • Significant or symptomatic amounts of ascites should be drained prior to enrollment.
  • Pain symptoms should be stable and should not require modifications in analgesic management prior to enrollment.
  • Ability to understand and the willingness to sign a written informed consent document.

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 any active autoimmune disease (i.e. psoriasis, extensive atopic dermatitis, asthma, IBD, M.S., uveitis, vasculitis), chronic inflammatory condition, or any condition requiring concurrent use of any systemic immunosuppressants or steroids for any reason would be excluded from the study. Any patient with an allo-transplant of any kind would be excluded as well. This would include those with a xenograft heart valve to avoid the potential risk of any immune reaction causing valvular degeneration. Mild-intermittent asthma requiring only occasional beta-agonist inhaler use or mild localized eczema will not be excluded.
  • 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.
  • Patient has a history of allergy or hypersensitivity to any of the study drugs or any of their excipients.
  • Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
