Mr. King continued, "We are also pleased to report that we have recently added additional clinical sites to the Cotara Phase II study, increasing the total participating centers from three sites to eight sites. We anticipate enhanced enrollment rates going forward, particularly in view of the quality and enthusiasm of the investigators we have recruited. We look forward to reporting further interim results from the Cotara program as we achieve additional enrollment milestones in the coming months."

The objectives of the open-label Phase II trial are to confirm the safety of the selected dose of Cotara and to obtain estimates of overall patient survival, progression-free survival and the proportion of patients alive at six months in GBM patients at first relapse. Patients in the trial are receiving a single infusion of Cotara by convection-enhanced delivery (CED), a technique that delivers the agent to the tumor with great precision. Patients receive brain scans at eight-week intervals post-treatment. Total enrollment in the 40-patient trial has reached the 20% completion mark. Patients who are continuing in the trials are being monitored for safety and overall survival, with the first dosed patient having reached eight months of survival post-treatment. Patient screening for the trial will continue until all 40 patients have been enrolled.
