ReACT is a Phase 2 study designed to determine if adding rindopepimut to standard of care Avastin® (bevacizumab) improves the outcomes for patients with recurrent EGFRvIII-positive glioblastoma. In August, 2013, Celldex announced that enrollment had been completed in an initial cohort (n=25) of Avastin refractory patients and that, based on early evidence of anti-tumor activity, the Company decided to add an expansion cohort of approximately 75 patients (Group 2C) to better characterize the potential activity of rindopepimut in this refractory patient population. As amended, the ReACT study is actively enrolling approximately 170 patients across three groups:
- Group 1 - Avastin naive, 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
Study endpoints include 6 month progression free survival rate, objective response rate, overall survival and safety and tolerability.
