Abstract

RBP-8000 is a double mutant cocaine esterase that rapidly metabolizes cocaine. This study was conducted to assess the pharmacokinetics of cocaine and cocaine-induced physiological effects in the absence (placebo) or presence of RBP-8000. Twenty-nine cocaine abusers were randomized 1:1 (active: placebo) to 4 sequences and 2 treatment periods. In the presence of RBP-8000, cocaine plasma exposures dropped by 90% within 2 min; cocaine-induced physiological effects were significantly reduced with higher extent and faster decrease in systolic blood pressure and pulse rate compared to placebo. This study provides strong evidence in support to use RBP-8000 as a pharmacotherapy for cocaine intoxication.
