Anesiva Announces Pivotal Phase 3 Clinical Trial of Adlea(TM) for Reducing Post-Surgical Pain Following Total Knee R...(of action results in site-specific effic...),Health

Adlea is a highly purified form of capsaicin (derived from chili peppers) that acts primarily on C-fiber neurons, which transmit long-term pain, by binding to and desensitizing the TRPV1 pain receptors. This leads to a prolonged, reversible and localized desensitization of the pain fibers. The drug generally has a short half-life of 1 to 2 hours, and is undetectable in the blood after 24 hours.

Adlea's short duration of systemic exposure relative to the longer duration of analgesia may offer a safe, additive treatment option in the management of post-surgical orthopedic pain. In clinical trials to date, adverse events have been similar in patients receiving Adlea or placebo. Adlea is also in clinical development for the treatment of pain associated with moderate to severe osteoarthritis.
