Infinity Pharmaceuticals, Inc., a drug discovery and development company, focuses on discovering, developing, and delivering medicines to patients for diseases with significant unmet need. Its lead product candidates include IPI-145 and IPI-443, inhibitors of the delta and gamma isoforms of phosphoinositide-3-kinase (PI3K); Retaspimycin HCl, a heat shock protein 90 inhibitor; and IPI-940, an inhibitor of fatty acid amide hydrolase. The company is pursuing a dual development path for IPI-145 in both hematologic malignancies and inflammation.

In addition, the company plans to initiate a Phase II signal-finding study in patients with rheumatoid arthritis. IPI-443 is undergoing preclinical studies to enable Phase I development. Retaspimycin HCl is in a Phase II trial in combination with docetaxel to treat patients with non-small cell lung cancer (NSCLC) and in an exploratory Phase Ib/II trial in combination with everolimus in NSCLC patients with a KRAS mutation.
