Eladur, an investigational transdermal drug patch for low back pain, did not meet goals in a double-blind study, according to a report by its maker, Durect.
Eladur delivers for up to three days bupivacaine, an FDA-approved long-acting local anesthetic used in regional anesthesia for local tissue infiltration, nerve block, and epidural and intrathecal anesthesia.
"Demonstrating efficacy against placebo in a chronic low back pain trial is challenging for any topical locally acting product," said James E. Brown, president and CEO of Durect. "We and Pfizer are continuing to analyze this most recent study and will work together to determine next steps."
