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

Eligibility Criteria

Inclusion Criteria

  • 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.

Exclusion Criteria

  • 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).
