- Remedy Plan Therapeutics
Participated · Equity · May 2025
Remedy Plan Therapeutics develops novel, hyperbolic NAMPT inhibitors intended to inhibit disease-associated NAMPT activity without fully turning the enzyme off, thereby avoiding on-target toxicity in healthy tissues. The company’s lead candidate is RPT1G. Remedy Plan plans to use recent financing to accelerate advancement of RPT1G into a Phase 1/2 trial in patients with acute myeloid leukemia (AML) and high-risk myelodysplastic syndromes (MDS). It says NAMPT is dysregulated in more than 20 diseases spanning oncology, autoimmunity, and metabolic disorders. Remedy Plan is a privately-held, clinical-stage company led by CEO and founder Greg Crimmins and is based in Gaithersburg, MD. The company cites prior failures of NAMPT inhibitors due to severe on-target toxicities and positions its approach as selectively avoiding those toxicities while still meaningfully inhibiting diseased cells.
