About Cotinga Pharmaceuticals Inc.Cotinga Pharmaceuticals is a clinical-stage pharmaceutical company that uses proprietary artificial intelligence technologies to pursue a targeted and transformational approach to treating cancer and other unmet medical needs. Cotinga’s CHEMSAS® technology is intended to accelerate the discovery and development of novel drug therapies, allowing the Company to build a pipeline of potential drug candidates faster and with a higher probability of success than traditional methods.

The Company’s lead compound, COTI-2, has a novel p53-dependent mechanism of action with selective and potent anti-cancer activity. P53 mutations occur in over 50% of all cancers. COTI-2 is initially being evaluated in combination with various standard of care chemotherapy regimens for the treatment of a wide spectrum of cancers in a Phase 1b/2a clinical trial at the MD Anderson Cancer Center at the University of Texas. The Company has secured orphan drug status in the United States for COTI‐2 for the treatment of ovarian cancer. Preclinical data suggests that COTI-2 could dramatically improve the treatment of cancers with mutations in the p53 gene.

The Company’s second lead compound, COTI-219, is a novel oral small molecule compound targeting the mutant forms of KRAS without inhibiting normal KRAS function. KRAS mutations occur in up to 30% of all cancers and represent a tremendous unmet clinical need and a desirable drug target. COTI-219 is undergoing IND-enabling studies to support a regulatory submission.
