Brief Summary

Indoximod was developed to inhibit the IDO (indoleamine 2,3-dioxygenase) enzymatic pathway, which is important in the natural regulation of immune responses. This potent immune suppressive mechanism h...

  • Must be 28 days from administration of antibody-based therapies (e.g., bevacizumab), tumor-directed vaccines, or cellular immune therapies (e.g., T cells, NK cells, etc).
  • Must be 56 days from administration of tumor-directed therapies using infectious agents (e.g., viruses, bacteria, etc).

  • .

Exclusion

  • Patients who cannot swallow indoximod pills are excluded.
  • Patients previously treated with indoximod are excluded.
  • Patients with DIPG who have been treated with any prior radiation or medical therapy are excluded.
  • Midline glioma that does not include significant brain stem involvement is not considered DIPG for enrollment purposes, and is excluded.
