Synta Provides Company Updates and Reports Fourth Quarter and Year-End 2012 Financial Results

-- Expects mid-year overall survival results from the GALAXY-1 trial for ganetespib in second-line non-small cell lung cancer –

-- Expects enrollment of the pivotal GALAXY-2 Phase 3 trial to commence this month --

-- Announces key addition to executive management team –

LEXINGTON, Mass.--(BUSINESS WIRE)--Mar. 14, 2013-- Synta Pharmaceuticals Corp. (NASDAQ: SNTA) today provided an update on recent progress with its clinical programs and reported financial results for the fourth quarter and year ended December 31, 2012.

“Over the past year, we have made strong progress in the development of ganetespib, our Hsp90 inhibitor,” said Dr. Safi Bahcall, President and CEO of Synta. “Interim results presented last year from our GALAXY-1 trial evaluating ganetespib as second-line treatment of non-small cell lung cancer showed encouraging clinical activity. We look forward to presenting more mature results from the 240-patient target population of this trial mid-year, and enrolling the first patient in our GALAXY-2 Phase 3 trial before the end of this month.”

“Ganetespib represents a distinct cancer treatment paradigm – targeting one protein, the chaperone, which simultaneously destabilizes a broad range of oncogenic pathways,” said Dr. Sumant Ramachandra, President of Research and Development. “This approach is differentiated: existing cancer therapies are generally either non-specific, for example anti-mitotic chemotherapies, or target one particular signaling protein involved in a limited number of cancer signaling pathways, for example tyrosine kinase inhibitors.”

“The clinical evidence to date, together with the preclinical results that show treatment with ganetespib changes the broader biology of cancer cells, reducing tumor aggressiveness, are encouraging,” continued Dr. Ramachandra. “Results expected later this year will be important in confirming the clinical activity and establishing the potential for ganetespib beyond lung cancer.”

The safety profile of ganetespib has been favorable in over 700 patients treated to date in more than 20 clinical trials. Transient, mild or moderate diarrhea has been the most commonly reported adverse event.

Key accomplishments in 2012

1. At the 2012 Congress of the European Society for Medical Oncology (ESMO), investigators reported results from the second interim efficacy analysis of the GALAXY-1 trial. There were 172 adenocarcinoma patients in the clinical database at the time of the September 10 cutoff for this analysis.

Highlights included:

a. An increase in overall survival was observed in adenocarcinoma patients treated with ganetespib plus docetaxel. A median overall survival of 7.4 months was observed in the docetaxel control arm, while median overall survival had not yet been reached in the ganetespib arm. Results for docetaxel were consistent with results from prior second line non-small cell lung cancer (NSCLC) therapy trials. Objective response rate and progression-free survival were also improved in the ganetespib arm.

b. Results in several GALAXY patient subpopulations, defined by pre-specified clinical and biomarker characteristics, showed a substantially improved survival difference between the control arm and ganetespib arm, as compared with the difference in the all-comer (intent-to-treat) adenocarcinoma patient population. These findings have been incorporated into the design of the GALAXY-2 trial, with the objective of enriching for patients likely to derive the greatest benefit from ganetespib treatment.

c. Clinical and preclinical results were presented that suggest ganetespib reduces or disrupts new blood vessel formation (angiogenesis) and the emergence of new lesions (metastases). Analyses of tumor samples from patients treated with ganetespib showed a reduction of levels of vascular endothelial growth factor (VEGF) and hypoxia induced factor-1alpha (HIF-1alpha), key drivers of angiogenesis and metastasis.

d. A favorable safety profile was observed with the ganetespib plus docetaxel combination in adenocarcinoma patients. Transient, mild-to-moderate diarrhea was the most common adverse event, consistent with observations from other clinical trials evaluating ganetespib.

2. Completed enrollment of the 240 adenocarcinoma patient target population of GALAXY-1 in October 2012.

3. Participated in an End-of-Phase 2 (EOP2) meeting with the Food and Drug Administration (FDA) to review plans for the GALAXY-2 Phase 3 trial. Synta has incorporated comments from the EOP2 meeting into the Phase 3 protocol and is initiating this trial.

4. Presented results at the American Society of Clinical Oncology (ASCO) meeting in June 2012 showing that common ocular toxicities seen with some Hsp90 inhibitors, but not observed in clinical trials with ganetespib or with 17-AAG, are associated with physicochemical properties that affect drug distribution to the eye.

5. Synta collaborators enrolled the first patients in investigator-sponsored trials evaluating ganetespib in combination regimens for treatment of ALK+ NSCLC, hormone receptor-positive metastatic breast cancer, multiple myeloma, acute myeloid leukemia, and rectal cancer.

6. Completed equity financings resulting in approximately $119 million of net proceeds to the company.

Ganetespib clinical updates


The 240 adenocarcinoma patient enrollment target for GALAXY-1 was achieved in October 2012. Twelve additional patients in screening at that time were also enrolled, yielding a total of 252 adenocarcinoma patients, with the last patient randomized in November 2012. An overall survival analysis of the all-comers (intent-to-treat; ITT) adenocarcinoma population was specified for six months from last patient enrolled. Based on current projections, Synta plans to conduct this analysis in mid-2013.

The GALAXY-1 protocol specified that enrollment of patients with either of two pre-specified biomarkers may continue, following completion of the targeted number of all-comers adenocarcinoma patients, in order to ensure a sufficient number of patients in each of these biomarker-defined subpopulations. We expect that approximately 60 additional such patients will be enrolled. Based on our current projections, we expect that the final PFS analyses for these GALAXY-1 biomarker-defined subpopulations will be conducted in the second half of 2013.


The GALAXY-2 Phase 3 trial has the same design as the GALAXY-1 trial. Approximately 500 patients with advanced adenocarcinoma NSCLC will be randomized 1:1 to treatment with docetaxel plus ganetespib or docetaxel alone. The same dose and schedule used in the GALAXY-1 trial will be used in the GALAXY-2 trial. Patients on both arms will receive docetaxel generally for four to six 21-day cycles, according to standard practice at their treatment center. After completion of docetaxel treatment, patients on the ganetespib arm are eligible to continue to receive ganetespib as monotherapy treatment until disease progression. The trial will be conducted in many of the 60 centers across Europe and North America that participated in the GALAXY-1 trial, together with up to 60 additional centers.

Results from an interim analysis of the GALAXY-1 trial conducted in September 2012 were used in selecting the eligibility criteria for the GALAXY-2 trial, in order to enrich for the patients most likely to derive the greatest benefit from ganetespib treatment. GALAXY-2 will enroll patients who have progressed following treatment with one prior platinum-containing regimen of chemotherapy and who were diagnosed with metastatic disease at least six months prior to study entry. This represents approximately 65% of the GALAXY-1 patient population.

Overall survival is the primary endpoint for GALAXY-2. Two event-driven interim analyses have been specified. Based on current projections and statistical assumptions, Synta expects these analyses, together with the final analysis, to occur in 2014.

Additional clinical updates

1. Results from an initial phase of the CHIARA trial, evaluating ganetespib monotherapy for treatment of ALK+ NSCLC naïve to ALK inhibitor therapy, will inform the decision as to whether to continue additional enrollment in this trial. Synta plans to provide additional updates regarding this program mid-2013.

2. Synta also plans to provide updates mid-year from the ongoing ENCHANT trial, designed to evaluate ganetespib monotherapy as first-line treatment of HER2+ and triple negative metastatic breast cancer.

3. New investigator-sponsored and cooperative group studies are being planned to evaluate ganetespib in combination with standard-of-care chemotherapies for the treatment of metastatic breast and ovarian cancers.

Elesclomol clinical update

In March 2011, the Gynecological Oncology Group (GOG) initiated a Phase 2 clinical trial of elesclomol, an oxidative stress inducer, in combination with paclitaxel for the treatment of persistent or recurrent ovarian, fallopian tube or primary peritoneal cancer for patients with total baseline serum lactate dehydrogenase (LDH) level less than 0.8 times the upper limit of normal (ULN). Synta has recently been informed that this trial has met the pre-specified efficacy requirement to advance to stage 2, indicating potential activity in this difficult-to-treat patient population that has limited treatment options.

Executive management team addition

In a separate release, the Company announced yesterday that Sumant Ramachandra, M.D., Ph.D., has joined Synta as President, Research and Development.

Fourth quarter and full year 2012 financial results

About Ganetespib

Ganetespib is a potent inhibitor of heat shock protein 90 (Hsp90) that is structurally unrelated to first-generation, ansamycin-related Hsp90 inhibitors. 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. Company-sponsored clinical studies with ganetespib include 1) the randomized GALAXY-1 and GALAXY-2 trials evaluating ganetespib in combination with docetaxel as second-line treatment of non-small cell lung cancer (NSCLC), 2) the CHIARA Phase 2 trial evaluating ganetespib monotherapy in ALK+ NSCLC, and 3) the ENCHANT Phase 2 trial evaluating ganetespib as first-line treatment for HER2+ and triple-negative metastatic breast cancer. In addition, ganetespib is being evaluated in investigator-sponsored trials for treatment of a number of solid tumor and hematologic cancer indications. Information on these trials can be found at

The safety profile of ganetespib has been favorable in over 700 patients treated to date in more than 20 clinical trials. Transient, mild or moderate diarrhea has been the most commonly reported adverse event.

About the GALAXY Trials

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 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. Many of the “client proteins” of Hsp90 – such as AKT, ALK, BCR-ABL, BRAF, EGFR, FLT3, HER2, HIF-1alpha, KIT, MET, PDGFRA, and VEGFR – are the targets of clinically validated cancer drugs. In preclinical studies, inhibiting Hsp90 causes the degradation of multiple client proteins and leads to cancer cell death.
