BURLINGTON, Mass., July 1, 2013 (GLOBE NEWSWIRE) -- Coronado Biosciences, Inc. (Nasdaq:CNDO), a biopharmaceutical company focused on the development of novel immunotherapy biologic agents for the treatment of autoimmune diseases and cancer, announced today that it has completed the enrollment of TRUST-I, its phase 2 clinical trial with TSO (Trichuris suis ova or CNDO-201) in 250 Crohn's disease patients.
"We are excited to have completed enrollment in our phase 2 TRUST-I trial and we expect to report top-line data in the fourth quarter of 2013," said Dr. Harlan F. Weisman, Coronado's Chairman and CEO. "This is a significant milestone for our TSO program as a potential game changer in the treatment paradigm of Crohn's disease and other autoimmune diseases. This accomplishment continues to demonstrate the strength of our clinical development program as we move closer to completing the first company-sponsored phase 2 trial and meeting our timeline projection for the results of the study."
TRUST-I is a randomized, double-blind, placebo-controlled, U.S. multicenter study designed to evaluate the safety and efficacy of TSO in Crohn's disease. The trial enrolled and randomized 250 patients with moderate-to-severe Crohn's disease to receive either 7500 ova or placebo once every 2 weeks, for 12 weeks. The final number of patients in the trial surpassed the target enrollment of 220 patients to accommodate individuals in the screening process when the trial's enrollment goal was achieved. The primary endpoint for the study is induction of response at 12 weeks, with induction of remission being a key secondary endpoint. Additional study details can be found at www.clinicaltrials.gov.
Coronado's development partner for TSO in Crohn's disease, Dr. Falk Pharma GmbH, is also conducting TRUST-II, a phase 2, double-blind, randomized, placebo-controlled, multi-center study in Europe to evaluate the efficacy and safety of three different dosages of TSO in active Crohn's disease. The results from a second interim analysis are expected in the second half of 2013.
TSO (Trichuris suis ova or CNDO-201), the microscopic eggs of the porcine whipworm, is a novel, orally administered, natural immunomodulator that regulates T-Cells and pro-inflammatory cytokines. The use of TSO as a therapeutic is based on the "hygiene hypothesis" and numerous animal and human studies. TSO was chosen as the biological agent of choice because it is not a human pathogen, and is spontaneously eliminated from the body within several weeks after dosing.
In February 2012, the company reported positive results from a phase 1 clinical study of TSO in patients with Crohn's disease, where TSO was shown to be safe and well tolerated. The phase 1 trial was a multi-center, sequential dose, dose-escalation, double-blind, placebo-controlled study of 36 patients with Crohn's disease.
Multiple investigator-sponsored clinical trials of TSO for the treatment of Crohn's disease, ulcerative colitis and multiple sclerosis have been completed, in which TSO demonstrated benefit with regard to accepted outcome measurements of remission of disease, and was shown to be well tolerated. In an open-label clinical trial with 29 patients reported in GUT in January 2005, TSO was shown to induce clinical remission in over 72 percent of patients with Crohn's disease after 24 weeks of treatment using the Crohn's Disease Activity Index as the primary outcome variable. As reported in the American Journal of Gastroenterology in April 2005, in a double-blind, randomized placebo-controlled trial in 54 patients with ulcerative colitis, TSO was shown to produce statistically significantly more responders than those treated with placebo (43.3% vs. 16.7%, p=.04).
