PHILLIPSBURG, N.J., Aug. 12, 2013 (GLOBE NEWSWIRE) -- Celldex Therapeutics, Inc. (Nasdaq:CLDX) Celldex Therapeutics recently completed enrollment in an initial cohort (n=25) of Avastin ® (bevacizumab) refractory patients in the Company's ongoing ReACT study of rindopepimut in EGFR vIII (v3)-positive glioblastoma (GBM). Based on early evidence of anti-tumor activity, including stable disease, tumor shrinkage and investigator-reported response, the Company has decided to add an expansion cohort of approximately 75 patients to better characterize the potential activity of rindopepimut in this refractory patient population. Enrollment in the expansion cohort has begun and, like the initial cohort, will evaluate rindopepimut plus Avastin.
- Group 1 - Avastin naïve, n= apx. 70, enrollment ongoing—patients randomized to receive either rindopepimut or KLH (administered as a control), each along with Avastin
- Group 2 - Avastin refractory, n= apx. 25, enrollment completed—patients receive rindopepimut plus Avastin in a single treatment arm
- Group 2C (C = Confirmatory) - Avastin refractory expansion, n = apx. 75, enrollment initiated—patients receive rindopepimut plus Avastin in a single treatment arm
