Indoximod is an Indoleamine 2,3-dioxygenase (IDO) pathway inhibitor. IDO is a tryptophan-catabolizing enzyme that tumors use to create a state of immunosuppression. [1]

The immunosuppressive activity of IDO leads to an increase in the number of T-regulatory cells, as measured by their Foxp3+/CD4+/CD25+ phenotype. Indoximod has also been shown to reduce the number of T-regulatory cells [2]. In MMTV-Neu mice, researchers looked at the activity of indoximod with and without paclitaxel [3]. The combination of docetaxel and indoximod is more toxic than docetaxel monotherapy.  A single 1200 mg dose of indoximod almost totally saturates the gut, and higher doses do not significantly increase peak serum levels. The single-agent phase I trial of indoximod demonstrated very good oral bioavailability and a mild toxicity profile with no significant myelosuppression, and no maximally tolerated dose was identified up to 2000 mg orally twice daily [1].

Blockade of IDO with indoximod enhanced the adoptive immunologic response to antigens and dendritic cell (DC) vaccines in LLC mouse models.
