Brief Summary
To evaluate the preliminary efficacy of the established dose of indoximod in combination with immune checkpoint inhibition as measured by the best overall response rate (ORR) (complete response (CR) + partial response (PR))across both standard of care agents administered sequentially in patients with unresectable stage III or stage IV melanoma

Outcome Measures
Primary Outcomes (3)
Overall Incidence of Adverse Events as a Measure of Safety and Tolerability
Phase 1 component: Evaluate the safety (adverse events - type, incidence, severity, duration, causality and treatment intervention) of the combination of indoximod and ipilimumab when given concomitantly. The safety and tolerability ipilimumab followed by Indoximod will be assessed by listing the overall incidence of AEs. The AEs will be summarized and classified by body system and by treatment group. The type, incidence, severity, and causality of each AE, the duration of the event, and any required treatment interventions will be tabulated. Physical examination results will be presented in the patient data listings. The DLT will be listed per dose level and treatment along with overall frequencies. The data from the expansion part (Phase II) will be used for this part of safety and tolerability assessment.
17 months
Phase 2 Dosing
Phase 1 component: To determine the recommended Phase 2 dose of indoximod in combination with ipilimumab in patients with unresectable melanoma. A minimum of nine patients will be treated depending on DLT. Each dose will be administered to a cohort of 3 patients. If 0 out of 3 or less than 2 out of 6 patients experienced a DLT at any given dose level, the dose escalation will proceed to the next dose level. The MTD is generally the largest dose level at which at most 1 out of 6 patients experiences a DLT. IF DLT is not reached at the highest dose level (1200mg twice daily), no further escalation will proceed and this dose level will be declared the recommended Phase II dose
22 months
Overall Response Rate
Phase 2 component: To evaluate the preliminary efficacy of the established dose of indoximod in combination with immune checkpoint inhibition as measured by the best overall response rate in patients with unresectable Stage III or Stage IV melanoma.

Study Arms (3)
Indoximod + Ipilimumab
EXPERIMENTALIndoximod will be administered at 1200mg BID by mouth. Ipilimumab administered intravenously at 3 mg/kg every three weeks for a total of four doses. Indoximod and ipilimumab will be dosed concurrently. Indoximod will be dosed twice daily on all days of each 21 day cycles (segment 1). Ipilimumab will be dosed on the 1st day of each 21 day cycle for the first 4 cycles. Indoximod dosing will continue after all 4 doses of ipilimumab are administered (segment 2, 28-day cycles). Patients will continue until they experience disease progression or limiting toxicity.
Indoximod + Pembrolizumab
EXPERIMENTALIndoximod will be administered at 1200mg BID by mouth. Pembrolizumab administered intravenously at 2 mg/kg every three weeks.
Indoximod + Nivolumab
EXPERIMENTALIndoximod will be administered at 1200mg BID by mouth. Nivolumab administered intravenously at 240 mg every 2 weeks.
Interventions
Initial dose of 600mg BID by mouth with escalation planned to 1200mg BID by mouth Dose escalation: * If 0 of the 3 subjects forming the first cohort experience RLT, 1200mg BID cohort will be enrolled * If 1 of the 3 subjects in any cohort experiences a RLT, then enrollment into that cohort will increase to a total of 6 subjects * If \> 1 of the 3-6 subjects experience a RLT, then the MTD has been exceeded and further enrollment into the cohort will cease * If \>1 subject at 600mg BID experiences a RLT, the dose will be de-escalated to 400mg BID. If \>1 subject at this level experiences a RLT, one additional de-escalation to 200mg BID is allowed Dosing cycles are 21 days in length during the combination immunotherapy component (first 4 cycles) and 28 days during indoximod monotherapy. Patients will continue until they experience disease progression or limiting toxicity Phase 2 Treatment Plan (Cohort 2) Will receive fixed dose of indoximod determined in phase 1
Ipilimumab administered intravenously at 3 mg/kg every three weeks for a total of four doses.
Pembrolizumab administered intravenously at 2 mg/kg every three weeks.
Eligibility Criteria
You may qualify if:
- Unresectable Stage III or Stage IV melanoma.
- Patients must have measurable disease, defined as lesions that can be accurately measure in in 2 perpendicular diameters with at least one diameter \> 20mm and the other \>10mm on conventional CT or MRI or 10mm x 10 mm by spiral CT.
- No systemic treatment in the previous 28 days.
- Age ≥18 years. Because no dosing or adverse event data are currently available on the use of ipilimumab or indoximod in patients \<18 years of age, children are excluded from this study.
- ECOG performance status ≤2 (Karnofsky ≥60% )
- Patients with known brain metastases will only be eligible after their tumors have been treated with definitive resection and/or radiotherapy and they are neurologically stable for at least 1 month off steroids.
You may not qualify if:
- Patients who have had molecular targeted therapy (including vemurafenib) or radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
- Patients who have had prior therapy with immune checkpoint inhibition or or indoximod are excluded from the trial.
- Any other cancer, unless the patient has been disease-free for ≥5 years
- Patients with laboratory evidence of pancreatitis are excluded.
- Patients with autoimmune disease
- Chronic use of immune-suppressive drugs (ie, systemic corticosteroids used in the management of cancer or non-cancer related illnesses, eg, COPD).
