Synta Provides Clinical Update and Reports First Quarter 2012 Financial Results

-Company announces plans to proceed into Phase 3 stage of the GALAXY Trial by year-end-

LEXINGTON, Mass.--(BUSINESS WIRE)--May. 3, 2012-- Synta Pharmaceuticals Corp. (NASDAQ: SNTA) today provided a clinical program update and reported financial results for the quarter ended March 31, 2012.

“This year we made significant progress in the clinical development of ganetespib, our lead Hsp90 inhibitor, for cancer,” said Safi Bahcall, Ph.D., President and CEO. “We have seen encouraging activity with ganetespib in two distinct areas – as a single-agent, in patients whose tumors exhibit certain specific genetic profiles, and in combination with chemotherapy, in our randomized, second-line lung cancer trial. These results, together with the favorable safety profile established in over 500 patients treated to date, support the broad potential of ganetespib for treating cancer patients.”

“Existing cancer therapies are generally either non-specific or target one particular signaling protein involved in one or a small number of cancer signaling pathways,” said Dr. Vojo Vukovic, Chief Medical Officer. “Chemotherapies are an example of the former while kinase inhibitors, such as Gleevec® and monoclonal antibodies such as Herceptin®, are examples of the latter. Ganetespib, on the other hand, targets one chaperone protein, Hsp90, which is required for proper functioning of multiple oncoproteins. Consequently, ganetespib inhibits many different tumor growth and signaling pathways simultaneously. This characteristic is best demonstrated by the clinical results observed in a diverse range of tumor types. Ganetespib has demonstrated single-agent activity in patients with mutated ALK, KRAS, and BRAF non-small cell lung cancer (NSCLC) as well as HER2+ and triple-negative breast cancer (TNBC). Ganetespib is the first Hsp90 inhibitor to demonstrate this broad range of activity with a favorable safety profile.”

The GALAXY trial is a Phase 2b/3 trial designed to compare standard-of-care docetaxel with or without ganetespib in a second-line advanced NSCLC treatment setting. The Phase 2b portion of this trial, targeted to enroll 240 patients, is designed to identify one or more patient populations, defined by outcomes of biomarker analysis and other disease characteristics, which are best suited for enrollment in the Phase 3 portion of the trial. An interim analysis for the first-stage, Phase 2b portion is currently in progress, with an announcement planned for later this quarter. Based on encouraging results seen to date, Synta plans to meet with regulatory agencies and advance to the second-stage Phase 3 portion of this trial before the end of the year.

Two clinical trials confirming ganetespib activity in crizotinib-naive ALK+ advanced NSCLC patients are also initiating: a company-sponsored, 100-patient, Phase 2 monotherapy trial and a Phase 1/2 trial in combination with crizotinib being conducted by Memorial Sloan Kettering Cancer Center. Preliminary results from the ganetespib monotherapy trial are expected by year-end.

In addition to NSCLC, ganetespib is also being evaluated as potential treatment for metastatic breast cancer. Clinical data presented from a Phase 2 investigator-sponsored trial at the San Antonio Breast Cancer Symposium in December 2011 provided strong evidence that Hsp90 inhibition may be a promising approach for treating both HER2+ and TNBC. Based on this encouraging data, investigators at Memorial Sloan Kettering Cancer Center intend to initiate a Phase 1/2 trial evaluating ganetespib in combination with paclitaxel and Herceptin® in HER2+ breast cancer, and ganetespib in combination with paclitaxel in TNBC. In addition, Synta is designing a global clinical trial also evaluating ganetespib in these two breast cancer patient populations. Additional details will be provided as these trials initiate.

Synta expects that a number of third-party sponsored trials evaluating ganetespib will commence or continue in 2012. These include trials in combination with radiotherapy, a randomized trial in elderly patients with acute myelogenous leukemia (AML) in combination with cytarabine, and a Phase 1/2 trial both as a single agent and in combination with VELCADE® for the treatment of multiple myeloma. The multiple myeloma trial is being conducted in collaboration with the Multiple Myeloma Research Foundation (MMRF). Enrollment in this study began in March 2012. These third-party trials further diversify the ganetespib clinical trial portfolio and could inform new potential applications for ganetespib.

Financial Results

Total revenue was $0.1 million for the first quarter in 2012 compared to total revenue of $1.1 million for the same period in 2011.

About Ganetespib

Ganetespib is a potent, small-molecule inhibitor of heat shock protein 90 (Hsp90). Hsp90 is a molecular chaperone required for the proper folding and activation of many cancer-promoting proteins, and is recognized as a key facilitator of cancer cell growth and survival. In preclinical experiments, ganetespib has shown activity in multiple tumor models both as a single agent and in combination with certain widely used cancer agents. Ganetespib is currently being evaluated in a broad range of cancer clinical trials. In these trials, ganetespib has shown clinical activity in heavily pretreated patients and has been well tolerated to date with no evidence of severe liver or common ocular toxicities seen with other Hsp90 inhibitors. 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 clinical trials with ganetespib can be found at

About the Phase 2b/3 GALAXY TrialTM in NSCLC

The Phase 2b/3 trial will evaluate treatment with ganetespib and docetaxel vs. docetaxel alone, with 1:1 randomization, in patients with Stage IIIB or IV NSCLC who have completed one prior systemic therapy for advanced disease. The first stage, Phase 2b portion, will assess efficacy as measured by progression-free survival in approximately 240 patients. Results from this stage will also be used to inform the choice of patient subpopulation, by biomarker or other disease characteristic for the second stage, Phase 3 portion. The second stage may enroll up to 600 patients. More information on the trial can be found at

About Non-small Cell Lung Cancer

Lung cancer is the leading cause of cancer-related mortality in the United States, with over 226,000 new cases and 160,000 deaths estimated in 2012 according to the American Cancer Society. The five year survival rate for advanced-staged lung cancer is approximately 4%. Approximately 85% of all lung cancers are classified as non-small cell. Estimates for the global incidence of ALK+ NSCLC range from 40,000 to 70,000 new cases per year.
