Synta Pharmaceuticals Reports First Quarter 2008 Financial Results

LEXINGTON, Mass.--(BUSINESS WIRE)--May 14, 2008--Synta Pharmaceuticals Corp. (NASDAQ: SNTA), a biopharmaceutical company focused on discovering, developing, and commercializing small molecule drugs to treat severe medical conditions, today reported financial results for the quarter ended March 31, 2008.

In the first quarter of 2008, the Company recorded $1.3 million of collaboration revenue under its partnership agreement with GlaxoSmithKline (GSK), which principally reflects the $80 million upfront payment received in November 2007 recognized ratably over the 15-year estimated life of the agreement. The Company reported a net loss attributable to common stockholders of $17.7 million, or $0.52 per basic and diluted share for the first quarter in 2008, compared to $74.9 million or $2.61 per basic and diluted share for the same period in 2007. Included in the net loss to shareholders for the quarter ended March 31, 2007 was a one-time, non-cash charge of $58.6 million for the fair value of the beneficial conversion of our preferred stock which we recognized upon the conversion of the preferred stock in connection with our IPO in February 2007.

As of March 31, 2008, the Company had $99.2 million in cash and cash equivalents compared to $115.6 million as of December 31, 2007.

Operational Highlights

"We are pleased with the progress being made in advancing our product pipeline," said Safi Bahcall, Ph.D., President and Chief Executive Officer of Synta. "We are excited by the growing recognition in the scientific and medical communities of the potential of the oxidative stress mechanism of action of elesclomol for treating melanoma and other cancer types. Enrollment in our Phase 3 SYMMETRY trial of elesclomol in metastatic melanoma is proceeding well. We remain committed to our goal of completing enrollment by the end of this year, with the progression-free survival primary endpoint data available shortly thereafter. In addition, as we have previously announced, we expect to introduce a sodium salt formulation of elesclomol in the second half of 2008. This will allow us to more conveniently explore the potential of elesclomol in treating other cancer indications; we expect to initiate clinical trials in one or more additional indications by the end of the year."

"We also continue to advance our other clinical-stage programs - our Hsp90 inhibitor, STA-9090, and our oral cytokine inhibitor, apilimod," said Dr. Bahcall. "We are enrolling patients in two Phase 1 dose escalation studies of STA-9090 in solid tumors and we expect to begin a third clinical trial of STA-9090 in hematological cancers in the second half of the year. As previously announced, we plan to enroll an additional cohort of patients in our Phase 2a study of apilimod in rheumatoid arthritis to explore a higher dose level."

Financial Results

Synta reported a net loss attributable to common stockholders of $17.7 million, or $0.52 per basic or diluted share for the quarter ended March 31, 2008, compared to $74.9 million or $2.61 per basic or diluted share for the same period in 2007. Included in the net loss to shareholders for the quarter ended March 31, 2007 was a one-time, non-cash charge of $58.6 million for the fair value of the beneficial conversion feature of our preferred stock which we recognized upon the conversion of the preferred stock in connection with our IPO in February 2007.

Research and development expenses were $16.2 million for the first quarter in 2008 compared to $13.5 million for the same period in 2007. General and administrative expenses were $3.6 million for the first quarter in 2008 compared to $3.5 million for the same period in 2007.

Financial Guidance

Based upon our current operating plans, our financial guidance for 2008 remains unchanged. We expect to end 2008 with between approximately $60 million and $75 million of cash, cash equivalents and marketable securities. This includes $40 million to $50 million in anticipated operational progress milestone payments from GSK, and assumes no additional funds from new partnership agreements or financing events.

About Elesclomol (Formerly STA-4783)

Elesclomol is a novel, injectable, investigational drug candidate that triggers apoptosis (programmed cell death) in cancer cells. Cancer cells operate at high levels of reactive oxygen species, or oxidative stress. Elesclomol is believed to act by increasing the level of oxidative stress in cancer cells even further, beyond sustainable levels, inducing apoptosis. This mechanism of action, called oxidative stress induction, represents a novel way of selectively targeting and killing cancer cells.

In a double-blind, randomized, controlled Phase 2b clinical trial in 81 patients with stage IV metastatic melanoma, elesclomol in combination with paclitaxel met the primary endpoint, doubling the median time patients survived without their disease progressing, compared to paclitaxel alone (p = 0.035). The most common adverse events in the elesclomol plus paclitaxel group included fatigue, alopecia, constipation, nausea, hypoaesthesia, arthralgia, insomnia, diarrhea, and anemia.

A pivotal Phase 3 clinical trial of elesclomol in combination with paclitaxel in patients with stage IV metastatic melanoma (the SYMMETRY(SM) trial) is ongoing; Phase 2 trials in other indications, and in combination with other agents, are planned. Elesclomol has received Fast Track and Orphan Drug designation from the FDA for metastatic melanoma, and the Phase 3 SYMMETRY trial has completed a Special Protocol Assessment process with the FDA. Information about the SYMMETRY trial can be found at www.clinicaltrials.gov.

(1) The $80 million non-refundable upfront payment we received from GSK in November 2007, together with the $260,000 estimated value of an option to require GSK to purchase $25 million of our common stock, is being recognized as collaboration revenue over the estimated 15-year performance period of the agreement. At March 31, 2008, total deferred revenue was approximately $78.2 million, of which $5.4 million was current and will be recognized as revenue during the next twelve months, and $72.8 million was long-term.
