Importantly, SAR’514 exhibits ex vivo efficacy using bone marrow mononuclear cells (BMMC) from MM patients in an autologous setting showing an active and efficient primary MM cell killing against MM cells from patients that have failed diverse therapies, including standard of care treatments. In summary, these results demonstrate the efficacy of SAR’514 for controlling MM tumors in vivo and ex vivo, and provide consistent support for its clinical development.
As compared to the control group in which only 20% of mice survived with a median survival day of 44.5 days, SAR'514 induced a significant mouse survival from 0.5 mg/kg to 5 mg/kg with an overall survival of 90% and a median survival day over 90 days. In summary, these results demonstrate the efficacy of SAR'514 for controlling MM tumors in vivo and provide consistent support for its clinical development.
