About Anesiva

Anesiva, Inc. seeks to be a leader in the development and commercialization of novel pharmaceutical products for pain management. The company's lead product candidate is Adlea, a novel small molecule formulation of capsaicin that is currently in development for the management of acute pain following orthopedic surgeries. Adlea has been shown in clinical trials to provide extended pain relief after only a single administration in multiple indications for site-specific, acute and chronic, moderate-to-severe pain.

In December 2008, Anesiva announced that a Phase 3 clinical trial of Adlea achieved its primary efficacy endpoint of reduced post-surgical pain versus placebo (p=0.03) following total knee arthroplasty (TKA) at four to 48 hours after surgery. The trial also met its key secondary endpoint with Adlea demonstrating a highly significant reduction in opioid medication consumption compared to placebo (p=0.005).

The Phase 3 TKA trial, known as ACTIVE-2, also showed that Adlea's safety profile of adverse events, wound healing, and wound sensory function were similar to placebo over the study duration.

Anesiva is based in South San Francisco, CA. For more information, go to www.anesiva.com.
