NV-5138[2] is an orally and centrally active small-molecule drug which is under development by Navitor Pharmaceuticals for the treatment of major depressive disorder (MDD).[3][1][4] It directly and selectively activates the mammalian target of rapamycin complex 1 (mTORC1) signaling pathway by binding to and modulating sestrin2, a leucine amino acid sensor and upstream regulatory pathway.[1][4][5] The mTORC1 pathway is the same signaling pathway that the NMDA receptor antagonist ketamine activates in the medial prefrontal cortex (mPFC) to mediate its rapid-acting antidepressant effects.[1][4] A single oral dose of NV-5138 has been found to increase mTORC1 signaling and produce synaptogenesis in the mPFC and to induce rapid antidepressant effects in multiple animal models of depression.[1][4] Like those of ketamine, these actions require the signaling of brain-derived neurotrophic factor (BDNF).[1] The antidepressant effects following a single dose of NV-5138 are long-lasting, with a duration of up to 7 days, and are similar to those of ketamine.[1][4] Based on these promising preclinical findings, efforts are underway to assess NV-5138 in clinical trials with human subjects.[1] By November 2019, NV-5138 had completed three phase I studies for the treatment of MDD.[3] In these studies, preliminary evidence of efficacy, tolerability, safety, and pharmacokinetics was observed,[6] and as of 2021 it was into Phase II trials.[7][8]
