Threshold Pharmaceuticals Announces Completion Of Patient Recruitment For Phase 2 TH-302 Pancreatic Cancer Study

Stocks in this article: THLD

Threshold Pharmaceuticals, Inc. (NASDAQ:THLD), announced today the completion of patient enrollment into the Company’s Phase 2 pancreatic cancer study with TH-302, a novel small molecule tumor selective Hypoxia-Activated Prodrug (HAP) that specifically targets tumor hypoxia and is applicable to a broad range of solid tumors. Enrollment in the study exceeded initial recruitment expectations. As a result, the company expanded the study’s enrollment target from the original 165 patients to at least 200 patients, consequently increasing the statistical power of the study to greater than 80%.

“We are pleased that the clinical investigator and patient communities have expressed strong support for this study of TH-302 in combination with gemcitabine compared to gemcitabine alone in patients with pancreatic cancer. It’s always encouraging to experience enthusiasm for a program and in this case, we are happy to report that enrollment was achieved faster than anticipated,” said Stewart Kroll, Senior Vice President, Clinical Operations and Biostatistics.

The Phase 2 trial is a multi-center, randomized, controlled, crossover clinical trial of TH-302 in combination with gemcitabine in patients with first line pancreatic cancer. The primary endpoint of the trial is progression-free survival. The secondary endpoints are overall response rate, overall survival, event-free survival, CA 19-9 response rate as well as various safety parameters. Tumor response is evaluated at baseline and every eight weeks using RECIST. Patients for whom monotherapy with gemcitabine is considered standard therapy were eligible for the trial. Patients were randomized equally into one of three cohorts: TH-302 at a dose of 240 mg/m 2 plus gemcitabine, TH-302 at a dose of 340 mg/m 2 plus gemcitabine, or gemcitabine alone. Patients who successfully complete six cycles of treatment without evidence of significant treatment-related toxicity or progressive disease may continue to receive treatment. If a patient experiences cancer progression on gemcitabine alone, the patient may cross over into one of the TH-302 plus gemcitabine cohorts. The primary efficacy analysis will be performed after a minimum of 144 events.
