PainReform Announces Initial Topline Data for PRF-110 Phase 3 Clinical Trial
TEL AVIV, Israel, Nov. 20, 2024 (GLOBE NEWSWIRE) -- PainReform Ltd. (NASDAQ:PRFX) ("PainReform" or the "Company"), a clinical-stage specialty pharmaceutical company focused on the reformulation of established therapeutics, today announced the receipt of partial topline data from its contract research organization (CRO), Lotus Clinical Research ("Lotus"), for the Phase 3 clinical trial evaluating PRF-110 in post-surgical pain management of patients undergoing bunionectomy.
Initial analysis of the topline data indicates that PRF-110 demonstrated statistically significant superiority over placebo in reducing pain during the first 48 hours following surgery. These findings underscore PRF-110's potential to provide effective pain relief during the critical early postoperative period.
However, data pertaining to the subsequent 24-hour period, which is essential for assessing the primary endpoint of the trial, is currently unclear due to incoherence of the data. PainReform is actively collaborating with Lotus to resolve this to complete the analysis of this portion of the data. At present, there can be no assurance that the effort to resolve the incoherence will be successful.
"We are cautiously encouraged by the statistically significant pain reduction observed in the initial 48 hours, highlighting PRF-110's promise as an effective solution for post-surgical pain," said Ehud Geller, Chairman and interim CEO of PainReform. "While we are addressing the data issues concerning the subsequent 24-hour period, we plan on providing updates as our analysis progresses and we gain a clearer understanding of PRF-110's efficacy across the full study follow-up period."
PRF-110 is PainReform's proprietary, oil-based, extended-release formulation of ropivacaine, a widely used local anesthetic. Designed to provide prolonged pain relief while reducing the need for opioids, PRF-110 has the potential to significantly enhance patient recovery and safety in the post-surgical setting.
About Phase 3 Clinical Trial
The bunionectomy Phase 3 trial is a randomized, double-blind, placebo- and active-controlled, multicenter study to evaluate the analgesic efficacy and safety of intra-operative administration of PRF-110 following unilateral bunionectomy. The study is conducted in two parts. In the first part, a total of 15 patients were enrolled in an open label study at a single site in which PRF-110 was administered intra-operatively to measure safety and plasma concentration levels. All safety requirements including plasma concentration levels were met, and the study proceeded to the second part. In the second part, we randomized 428 patients. PRF-110 was administered intra-operatively and patients were divided into three cohorts, PRF-110, Naropin® (ropivacaine), and placebo in a 2:2:1 ratio. The primary efficacy endpoint is mean area under the curve, or AUC, of the numerical rating scale, or NRS, of pain intensity scores over 72 hours (AUC0-72) for PRF110 compared with placebo. Secondary efficacy endpoints include mean AUC0-72 of the NRS of pain intensity scores for PRF110 compared with plain ropivacaine, total post-surgery opioid consumption (in morphine equivalents) over 72 hours for PRF110 compared with saline placebo, the proportion of subjects who are opioid-free through 72 hours for PRF110 compared to that of plain ropivacaine, the total postoperative opioid consumption through 72 hours for PRF110 compared to that of plain ropivacaine. Safety endpoints include incidence of treatment emergent adverse events and serious adverse events, physical examination, vital signs and wound healing. If the first Phase 3 clinical trial of patients undergoing bunionectomy is successful, we plan to initiate a second trial for pain treatment of hernia repair operations.
