PRF-110 is a unique, sustained-release, oil-based solution formulation of ropivacaine intended for administration into surgical sites for the prevention of postoperative pain. The formulation is designed to have an effect for up to 72 hours. It is postulated that PRF-110 will improve postoperative pain management by providing prolonged pain relief at the surgical site; thereby, reducing the amount of systemic analgesia needed after surgery. The slow, local release of ropivacaine following administration of PRF-110 has been demonstrated in dissolution studies, in postoperative pain studies in animals, in an experimental pain study in human volunteers, and in an open-label Phase 2 hernia repair trial to result in very low plasma concentrations of drug, therefore reducing the probability of systemic adverse events. This is a randomized, double-blind study to evaluate the efficacy and safety of PRF-110 compared with saline placebo and with ropivacaine hydrochloride injection administered intraoperatively in subjects undergoing unilateral bunionectomy.
PRF-110 is a viscous, yellowish clear oily solution of ropivacaine intended for administration into surgical sites to provide post-operative analgesia. The pharmacokinetic profile for PRF-110 suggests that its effect could last up to 72 hours. This is A Phase 3, Randomized, Double-Blind, Saline Placebo- and Active-Controlled, Multicenter Study to Evaluate the Analgesic Efficacy and Safety of Intra-operative Administration of PRF-110 Following Unilateral Bunionectomy
