BRANFORD, Conn., June 1 /PRNewswire-FirstCall/ -- CuraGen Corporation (Nasdaq: CRGN) today presented encouraging results from the ongoing Phase I/II study of CR011-vcMMAE for the treatment of unresectable Stage III or Stage IV melanoma. The results were presented by Dr. Patrick Hwu, Co-Principal Investigator, and Professor, Chairman, Dept. of Melanoma Medical Oncology at The University of Texas, M.D. Anderson Cancer Center.

"In this heavily pretreated group of patients with primarily Stage IV disease, the observation of dose-dependent objective responses, tumor shrinkage, and encouraging early progression-free rate at 12 weeks at doses in the anticipated active range, leads us to believe that CR011-vcMMAE could be a potentially useful treatment for patients with advanced melanoma," commented Dr. Timothy Shannon, President and Chief Executive Officer of CuraGen Corporation. "Based on these promising results in melanoma we have expanded the CR011-vcMMAE development program to include a Phase II trial in metastatic breast cancer, and are also exploring additional doses and schedules to further optimize the activity of this antibody-drug conjugate."

As of April 4, 2008, forty patients were treated in this first-in-man Phase I/II study including a total of 32 patients in the Phase I dose-escalation portion of the trial that aimed to identify the safety and maximum tolerated dose (MTD) of CR011-vcMMAE and 8 patients in the ongoing Phase II portion of the study. During Phase I, doses of CR011-vcMMAE between 0.03 mg/kg to 2.63 mg/kg were evaluat
