  Synta Provides Clinical Updates and Reports First Quarter 2013 Financial

Business Wire

LEXINGTON, Mass. -- April 30, 2013

Synta Pharmaceuticals Corp. (NASDAQ: SNTA) today provided clinical updates and
reported financial results for the first quarter ended March 31, 2013.

Clinical Updates

Interim results from the randomized GALAXY-1 Phase 2b/3 trial, which compares
docetaxel with and without Synta’s investigational Hsp90 inhibitor ganetespib
for the second-line treatment of advanced non-small cell lung cancer (NSCLC),
will be presented at the American Society for Clinical Oncology (ASCO) in June
2013. Based on current projections, the company expects final progression-free
survival and updated overall survival results from GALAXY-1 will be presented
in the second half of 2013.

As previously announced, the first patients have been enrolled in the
confirmatory GALAXY-2 Phase 3 trial in non-small cell lung adenocarcinoma,
evaluating the same treatments and regimens as in the GALAXY-1 trial. Based on
current projections, the company expects to conduct interim and final analyses
for the overall survival primary endpoint of the GALAXY-2 trial in 2014.

Data collection continues for the CHIARA and ENCHANT trials, evaluating
ganetespib monotherapy in ALK+ NSCLC and metastatic breast cancer,
respectively. Results from these trials are expected to be presented in the
second half of 2013.

Financial Results

There were no revenues in the first quarter in 2013, compared to total revenue
of $0.1 million for the same period in 2012.

Research and development expenses were $16.4 million for the first quarter in
2013, compared to $12.1 million for the same period in 2012. General and
administrative expenses were $3.9 million for the first quarter in 2013,
compared to $2.6 million for the same period in 2012.

The Company reported a net loss of $20.7 million, or $0.30 per basic and
diluted share, in the first quarter of 2013, compared to a net loss of $15.1
million, or $0.27 per basic and diluted share, for the same period in 2012.

As of March 31, 2013, the Company had $90.4 million in cash, cash equivalents
and marketable securities, compared to $100.6 million in cash, cash
equivalents and marketable securities as of December 31, 2012.

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 April 30, 2013.


Based on our current operating levels the Company expects its cash resources
of approximately $90.4 million will be sufficient to fund operations into the
second quarter of 2014. This estimate assumes no additional funding from new
partnership agreements or equity financing events, and that the timing and
nature of certain activities contemplated for 2013 and 2014 will be conducted
subject to the availability of sufficient financial resources.

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 over 20 clinical trials including trials in
lung, breast, colorectal, and hematologic malignancies. Information on these
trials can be found at

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.
