Synta Announces Fast Track Designation Granted for Ganetespib in Non-Small Cell Lung Adenocarcinoma

LEXINGTON, Mass.--(BUSINESS WIRE)-- Synta Pharmaceuticals Corp. (NAS: SNTA) announced today that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to the investigation of ganetespib, the Company's lead Hsp90 inhibitor drug candidate, to improve overall survival when administered in combination with docetaxel for the treatment of patients with metastatic non-small cell lung adenocarcinoma who have progressed following one prior chemotherapy regimen. FDA's Fast Track Drug Development Program is designed to facilitate the clinical development and expedite the review of drugs that are intended to treat serious medical conditions and that demonstrate the potential to fill unmet medical needs.

"We are very pleased that FDA has granted this important designation to the ganetespib development program," said Safi Bahcall, President and CEO of Synta. "We look forward to continued progress and bringing ganetespib to cancer patients as quickly as possible."

Ganetespib is currently being evaluated as a treatment of non-small cell lung adenocarcinoma in the GALAXY program, consisting of the GALAXY-1 Phase 2b/3 all-comer trial and the GALAXY-2 Phase 3 trial enriched for patients most likely to benefit from ganetespib treatment.

About Ganetespib

Ganetespib, an investigational drug candidate, is a selective inhibitor of heat shock protein 90 (Hsp90), a molecular chaperone which controls the folding and activation of a number of client proteins that drive tumor development and progression. Many solid and hematologic tumors are dependent on Hsp90 client proteins including proteins involved in "oncogene addiction" (ALK, HER2, mutant BRAF and EGFR, androgen receptor, estrogen receptor, JAK2); proteins involved in resistance to chemotherapy and radiation therapy (ATR, BCL2, BRCA1/2, CDK1/4, CHK1, survivin, and WEE1); proteins involved in angiogenesis (HIF-1alpha, VEGFR, PDFGR, and VEGF); and proteins involved in metastasis (MET, RAF, AKT, MMPs, HIF-1alpha, and IGF-1R). In preclinical models, inhibition of Hsp90 by ganetespib results in the inactivation, destabilization, and eventual degradation of these cancer-promoting proteins. Ganetespib is being evaluated in trials in lung cancer, breast cancer, and other tumor types. The most common adverse event seen to date has been transient, mild or moderate diarrhea, which has been manageable with standard supportive care. Information on these trials can be found at Ganetespib has received Fast Track designation from FDA for second-line treatment of non-small cell lung adenocarcinoma in combination with docetaxel.

About the GALAXY Program

The GALAXY (Ganetespib Assessment in Lung cAncer with docetaXel) program consists of two randomized trials comparing the combination of ganetespib and docetaxel versus docetaxel alone in patients with Stage IIIB/IV NSCLC who have received one prior systemic therapy: a 300-patient Phase 2b/3 trial (GALAXY-1) to determine the patient population most likely to derive benefit from ganetespib, and a 500-patient confirmatory Phase 3 trial (GALAXY-2). More information about the GALAXY trials can be found at (NCT01348126 and NCT01798485).

About Lung Cancer

Lung cancer is the leading cause of cancer-related death in the world, accounting for nearly 1.4 million deaths in 2008, according to the World Health Organization. The five-year survival rate for this disease is approximately 16%; over half of people with lung cancer die within one year of being diagnosed. In the U.S., the American Cancer Society estimates that 228,000 cases of lung cancer will be diagnosed in 2013. Non-small cell adenocarcinoma comprises about 40% of all lung cancer.
