Infinity Pharmaceuticals, Inc.
Drug Names(s): IPI-504, MEDI561, MEDI-561, retaspimycin hydrochloride for injection
Description: IPI-504 is a proprietary agent that has demonstrated in preclinical studies to potently and selectively inhibit Heat Shock Protein 90 (Hsp90), thereby killing cancer cells. IPI-504 preferentially targets and accumulates in tumor tissues, sparing healthy tissues. In preclinical studies it has demonstrated a broad potential to treat cancer as both a single agent as well as in combination with existing anti-cancer drugs. IPI-504 is currently delivered in a water-based formulation.
Hsp90 is a therapeutic target for the treatment of cancer. Proteins are the mainstay of structural and signaling elements of all cells. Hsp90 functions to stabilize and maintain the equilibrium of proteins in the cancer cell, thereby allowing a cancer cell to survive despite an abundance of misfolded and unstable proteins.
Deal Structure: IPI-504 is Infinitys novel, proprietary agent.
