The results of this study are being finalized to initiate end of Phase 2 discussions with U.S. and European regulatory agencies to define the next steps in the development plan for this combination therapy. These interim results were initially presented at the Annual Meeting of the American Society of Hematology (ASH) (Free ASH Whitepaper) in December 2015.
"We are encouraged by the interim overall response rate results of this Phase 2 trial, which demonstrated that 23 of 30 patients, or 77%, responded to treatment, and anticipate further updates to the data set," stated Steve Fruchtman, M.D., Chief Medical Officer of Onconova. "Of note, 84% of HMA-naïve patients responded to this novel combination. We look forward to discussing these results, and the longer-term follow-up from this study, with U.S. and European regulatory agencies in order to define the next step of development for this combination therapy."
