REG1, the anticoagulant aptamer that inhibits Factor IXa (not a typo), is called pegnivacogin; REG2, the reversal agent for pegnivacogin, is called anivamersen. RGDO is using the name, Revolixys Kit to connote the two agents as a system.
I remain pretty skeptical of this approach to anticoagulation/reversal and to RDGO's attempt to pursue the ACS indication all by otself.
