Safety of Navoximod and NLG802 With Stereotactic Body Radiotherapy (SBRT) Treatment of Advanced Solid Tumors

This early phase trial proposes to study of stereotactic body radiation therapy (SBRT) with navoximod and NLG802, a prodrug of indoximod. Combinations of immune-oncology (IO) agents with complementary mechanisms as well as radiation represent a promising strategy to improve response rates to immunotherapy. Radiation therapy induces immunogenic cell death, increases production of tumor specific antigens, enhances TH cell functioning, and modulates immunosuppressive cell populations such as T regulatory cells and myeloid derived suppressor cells.
