Pacira sNDA Resubmitted on Exparel for Pain
FDA has accepted a Pacira Pharmaceuticals supplemental NDA resubmission seeking expansion of its Exparel (bupivacaine liposome injectable suspension) label to include administration via nerve block for prolonged regional analgesia. The agency has set a user fee review action target date of 4/5/2018. Exparel is currently indicated for single-dose infiltration into the surgical site to produce postsurgical analgesia.
FDA issued a complete response letter in 2015 on the original submission. At the time, the agency said Pacira would need to conduct additional Phase 3 studies on Exparel before it resubmitted the application. It requested new trials based upon Exparel’s expected use for a broad spectrum of nerve blocks and not limited to the narrow indication of a single nerve block, the company said.
The sNDA is based on data from a Phase 3 study of Exparel in femoral nerve block in the lower extremity, and a Phase 3 study in brachial plexus block for shoulder surgeries (upper extremity), the company says. It also includes safety and pharmacokinetic data through 120 hours, it adds.
The product combines bupivacaine with DepoFoam that delivers medication over a desired time period. “By utilizing the DepoFoam platform, a single dose of Exparel delivers bupivacaine over time, providing significant reductions in cumulative pain scores with a 45% decrease in opioid consumption,” Pacira says.
