Approval Letter Other 204803 (Jan 1, 2022)
The FDA issued a Complete Response letter for DURECT Corporation's New Drug Application (NDA) 204803 for POSIMIR (bupivacaine extended-release solution), indicating that the application cannot be approved in its current form. The primary reasons for non-approval are insufficient clinical data to demonstrate the safety of POSIMIR, specifically regarding adverse events related to shoulder joints, skin/underlying tissues (bruising, hematoma, pruritus, dehiscence), and neurologically related adverse events (dizziness, dysgeusia, headache, hypoesthesia, paresthesia, somnolence). The letter outlines specific additional studies required to characterize the risk profile and details requirements for a comprehensive safety update.
