Navoximod (formerly NLG 919, GDC 0919), a small molecule, orally bioavailable, immune checkpoint inhibitor, is being developed by NewLink Genetics for the treatment of solid tumours. Navoximod is a potent IDO (indoleamine-(2,3)-dioxygenase) pathway inhibitor with Ki/EC50 of 7 nM/75 nM. Upon administration, navoximod targets and binds to IDO1, a cytosolic enzyme responsible for the oxidation of the essential amino acid tryptophan into kynurenine. By inhibiting IDO1 and decreasing kynurenine in tumor cells, this agent increases tryptophan levels, restores the proliferation and activation of various immune cells, including dendritic cells (DCs), natural killer (NK) cells, and T-lymphocytes, and causes a reduction in tumor-associated regulatory T-cells (Tregs). Activation of the immune system, which is suppressed in many cancers, may induce a cytotoxic T-lymphocyte (CTL) response against the IDO1-expressing tumor cells. IDO1 is overexpressed by a variety of tumor cell types and plays an important role in immunosuppression. Tryptophan depletion is associated with immunosuppression caused by T-cell suppression. Navoximod is under investigation in clinical trial NCT02048709 (Indoleamine 2,3-Dioxygenase (IDO) inhibitor in advanced solid tumors).

Curator's Comment: The recommended dose of navoximod monotherapy was determined as 1000 mg orally BID, and could be considered 1000 mg orally BID in combination with atezolizumab. Navoximod as monotherapy and in combination with atezolizumab was well tolerated in Japanese patients with advanced solid tumours. https://www.ncbi.nlm.nih.gov/pubmed/31124055
In this Phase I trial six dose levels of NLG919 are proposed for evaluation: 50, 100, 200, 400, 600 and 800 mg orally q12 h for 21 of 28 days in repeating cycles.

HeLa cells were seeded in 96-well culture plates at a density of 1 × 104 per well. On the next day, human IFN-γ (10 ng/mL) and compounds in a total volume of 200 μL culture medium containing 15 μg/mL of L-tryptophan were added to the cells. After incubation for 24 h, 140 μL of the supernatant was mixed with 10 μL of 6.1 N trichloroacetic acid and the mixture was incubated for 30 min at 50 °C. The reaction mixture was then centrifuged for 10 min at 2500 rpm to remove sediments. 100 μL of the supernatant was mixed with 100 μL of 2% (w/v) p-dimethylaminobenzaldehyde in acetic acid and measured at 480 nm.
