Synta Pharmaceuticals Corp. (NASDAQ: SNTA) today announced scheduled
presentations at the 2013 ECCO-ESMO-ESTRO European Cancer Congress in
Amsterdam, The Netherlands.

“Ganetespib in combination with docetaxel versus docetaxel alone in second
line adenocarcinoma patients with KRAS mutations and elevated LDH levels”

Abstract #: 3416
Date and Time: September 29, 2:00 – 4:30 PM CEST
Presenter: Dean Fennell, M.D., Ph.D., University of Leicester, United Kingdom

Interim results from the on-going GALAXY-1 Phase 2b/3 trial that were
previously presented at ASCO 2013 will be reviewed. Additional details on the
outcomes of patient subgroups with mutated KRAS and elevated LDH will also be

Synta expects that results from a future analysis of the GALAXY-1 trial will
be presented at the 2013 World Conference on Lung Cancer in Sydney, Australia
during the week of October 27.

“Antimetastatic activity of ganetespib: Preclinical studies and assessment of
progressions due to new lesions in the GALAXY-1 NSCLC trial”

Abstract #: 3517
Date: September 29, 2:00 – 4:30 PM CEST
Presenter: Vojo Vukovic, M.D., Ph.D., Synta Pharmaceuticals

Results demonstrating the anti-angiogenic and anti-metastatic properties of
ganetespib in preclinical cancer models will be presented.

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.
