Synta Pharmaceuticals Provides Clinical Update and Reports Second-Quarter 2011 Financial Results

LEXINGTON, Mass., Aug 04, 2011 (BUSINESS WIRE) -- Synta Pharmaceuticals Corp. (NASDAQ: SNTA) today reported financial results for the quarter ended June 30, 2011 and provided an update on recent progress with its clinical programs.

Ganetespib Clinical Update

"The results presented at ASCO in June and at the IASLC World Conference on Lung Cancer in July showed that ganetespib, administered as a monotherapy, is clinically active with a favorable safety profile," said Safi Bahcall, Ph.D., President and Chief Executive Officer. "Activity has been seen now in multiple tumor types at dose levels that have been well tolerated, without the serious liver toxicities or common ocular toxicities seen with other Hsp90 inhibitors, consistent with the safety profile established in the over 400 patients treated to date. These findings of clear single-agent activity, with favorable safety, represent an important milestone for the Hsp90 field and create exciting potential for ganetespib to be the first Hsp90 inhibitor to market."

"Based on the encouraging results and discussions with our medical advisers, in early 2012 we intend to initiate new trials in lung cancer and breast cancer to focus on specific patient populations that appear to derive the greatest benefit," continued Dr. Bahcall. "These trials will complement our ongoing Phase 2b/3 GALAXY trial in 2nd line NSCLC in terms of providing promising, additional paths to registration."

"The GALAXY trial is proceeding as planned, with over 50 sites across 15 countries expected to be initiated by the end of September, and interim data expected to be available in early 2012," continued Dr. Bahcall. "In addition, we are actively engaged in a number of partnership discussions, for several of our clinical-stage and preclinical-stage programs, and continue to expect to announce one or more partnerships by the end of the year."

Results of the Phase 2 single agent trial of patients with NSCLC presented at ASCO showed an overall disease control rate of 54% in a broad, heavily pretreated patient population with advanced progressive disease. Particularly promising activity was seen in certain patient populations with specific tumor genetic profiles: seven out of eight patients with ALK gene rearrangement achieved durable disease control or target lesion tumor shrinkage, and eight out of thirteen patients with KRAS mutation showed shrinkage of target tumor lesions. The most common adverse event seen to date has been diarrhea, which has been manageable with standard supportive care.

An investigator-sponsored Phase 2 trial in combination with dutasteride in castration-resistant prostate cancer was initiated in the second quarter. Previously announced clinical trials in multiple myeloma in combination with bortezomib (VELCADE®) and in combination with radiotherapy will begin in the second half of 2011. Details regarding additional trials, planned for 2012, will be announced later this year or early 2012.

Synta will present results from a Phase 1 trial of ganetespib in combination with docetaxel in solid tumors at the European Multidisciplinary Cancer Congress in Stockholm, Sweden on September 23-27, 2011.

Additional Pipeline Program Updates

The Phase 1 trial of elesclomol in acute myeloid leukemia and the Phase 2 gynecological oncology group trial in ovarian cancer continue to advance; a Phase 2 non-small cell lung cancer trial is expected to initiate in 2012.

The CRACM ion channel program for the treatment of inflammatory and auto-immune diseases has achieved certain important preclinical milestones, and is progressing on two fronts - the preclinical candidates partnered with Roche, which continue to advance, and certain new internal, fully owned, drug candidates which are showing promising therapeutic profiles.

Financial Results

Total revenue was $1.3 million for the second quarter in 2011 compared to total revenue of $3.4 million for the same period in 2010. The Company reported a net loss of $12.5 million or $0.30 per basic and diluted share for the second quarter in 2011, compared to a net loss of $9.1 million, or $0.22 per basic and diluted share for the same period in 2010.

Research and development expenses were $10.4 million for the second quarter in 2011 compared to $9.7 million for the same period in 2010. General and administrative expenses were $2.9 million for the second quarter in 2011 compared to $2.7 million for the same period in 2010.

In April 2011, Synta raised approximately $35.2 million from the sale of approximately 7.2 million shares of its common stock in an issuer-directed registered direct offering. The shares were sold directly to investors without a placement agent, underwriter, broker or dealer, and no warrants were issued or discounts offered as part of this transaction. Approximately 1.6 million shares were sold to certain of the Company's directors and the remainder of the shares were sold to institutional investors. The proceeds to the Company were approximately $34.8 million after deducting estimated offering expenses payable by the Company.

As of June 30, 2011, the Company had $62.9 million in cash, cash equivalents and marketable securities compared to $51.0 million in cash, cash equivalents and marketable securities as of December 31, 2010.

More detailed financial information and analysis may be found in the Company's Quarterly Report on Form 10-Q, which was filed with the Securities and Exchange Commission (SEC) on August 4, 2011.

The Company's existing S-3 universal shelf registration statement expires August 28, 2011. Today, Synta filed a new shelf registration statement with the SEC. This shelf registration, once declared effective, will allow the Company to sell up to $150 million of various types of securities including up to $35 million of shares of common stock pursuant to the Company's equity line of credit facility. Upon its effectiveness, the Company's existing shelf registration statement will be terminated. The Company has no immediate plans to offer or sell any of its securities. The terms of any future sale or issuance of securities under the new registration statement would be set forth in a prospectus supplement and filed with the SEC in connection with any such sale or issuance.

Guidance

Based on the current operating plan, Synta expects cash resources will be sufficient to fund operations into the second half of 2012. This estimate assumes no additional funds from new partnership agreements, equity financing events, or use of the $35 million equity line of credit available to Synta. Certain activities contemplated for 2012 would be conducted subject to the availability of additional financial resources.

About Ganetespib

Ganetespib (formerly STA-9090) is a potent, synthetic, 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 diarrhea, which has been manageable with standard supportive care. Information on clinical trials with ganetespib can be found at http://clinicaltrials.gov/ct2/results?term=ganetespib.

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 histology or biomarker, for the second stage, Phase 3 portion. The second stage will assess efficacy as measured by overall survival, and will enroll between 400 and 600 patients. Interim results from the first-stage portion of the trial are expected in early 2012. More information on the trial can be found at http://clinicaltrials.gov/ct2/show/NCT01348126?intr=%22STA-9090%22&rank=15.
