Anesiva, Inc. Launches Needle-Free Zingo(TM) to Reduce Pain

SOUTH SAN FRANCISCO, Calif., June 30 /PRNewswire-FirstCall/ -- Anesiva, Inc. today announced that it has launched its first commercial product, Zingo(TM) (lidocaine hydrochloride monohydrate) powder intradermal injection system. Zingo is an easy-to-administer, single-use, needle-free system that reduces the pain associated with peripheral intravenous (IV) line placements and blood draws in children three to 18 years of age. Zingo works quickly, within one to three minutes, to relieve pain at the needle insertion site.

“Zingo is the first easy-to-administer, fast-acting local anesthetic that could lead to a paradigm shift in the approach to venous access procedures such as drawing blood and placing IV lines in children,” said William T. Zempsky, M.D., Associate Professor, Department of Pediatrics, University of Connecticut; Associate Director, Pain Relief Program, Connecticut Children’s Medical Center, Hartford, who led the pediatric trials of Zingo. “Because available topical anesthetic creams can take up to 30 to 60 minutes to work, healthcare providers have had to sacrifice patient comfort when performing the numerous peripheral venous access procedures that occur each day. Zingo will be a source of relief to both them and the children and parents they deal with every day.”

“The commercial launch of Zingo is a major milestone that is notable both for our company and for patients. We are fully committed to driving successful market introduction for this exciting new product,” said Michael L. Kranda, Anesiva’s president and chief executive officer.

Driving Penetration and Uptake for Large Unmet Need

“We are initially focusing our efforts on the children’s hospitals and academic medical centers with large pediatric units which facilitate the majority of acute and chronic pediatric care. Many of the patients served in these hospitals undergo peripheral venous access procedures repeatedly, and are undertreated, indicating a significant unmet medical need,” said Nancy E. Donahue, senior vice president, sales and marketing. Anesiva estimates that approximately 18 million pediatric peripheral venous access procedures are performed annually in U.S. hospitals.

Anesiva and its co-promotion partner Sagent Pharmaceuticals, Inc. are working in tandem to educate caregivers about the importance of addressing peripheral venous access pain in children, and to ensure Zingo availability through hospital pharmacies. Anesiva’s seasoned team of 15 hospital-based regional account managers with an average of 14 years’ industry experience, led by two directors who have a combined 30 years’ experience, will drive the launch of this product in the United States. Sagent has assigned 15 field representatives, all of whom have an average of more than 18 years’ hospital selling experience and whose national account representatives have an average of 25 years of hospital sales experience.

Zingo is currently manufactured with established, approved processes. Anesiva continues to pursue Zingo manufacturing scale-up in order to reduce cost of goods and meet anticipated increasing market demand.

Anesiva intends to grow a global brand for Zingo through geographically based license and distribution agreements with companies that have expertise in hospital-based markets in their territories, and has already entered into agreements for several major markets. Sigma Tau SpA will market Zingo in most major European markets; Medical Futures, Inc. is responsible for commercializing Zingo in Canada; and Green Vision Company will commercialize Zingo in several countries in the Middle East. Planning for local regulatory filings for marketing approval is underway. Discussions for license and distribution agreements in other major markets are in progress. Anesiva also has established a joint venture in China for the assembly of Zingo devices using U.S.-sourced components.

About Zingo

Peripheral venous access procedures are among the most frequently reported painful events in hospitalized children.(1) The American Pain Society and the American Academy of Pediatrics, among other organizations, have developed recommendations that emphasize the importance of minimizing procedural pain in children whenever possible.(2) However, despite the existence of these recommendations, children undergoing these procedures remain largely under- treated.(3)

Zingo is an easy-to-administer, single-use, needle-free system that delivers sterile lidocaine powder to provide topical, local analgesia to reduce the pain associated with peripheral IV insertions or blood draws, approved for use in children aged three to 18. Zingo’s rapid onset of action allows intravenous line placement or venipuncture to begin one to three minutes after administration. In clinical trials, the most common adverse events with Zingo were redness, red dots and swelling. For full Zingo prescribing information, go to http://www.zingo.com.

A supplemental New Drug Application (sNDA) is under FDA review to expand Zingo’s indicated use to include adults. FDA action on the sNDA is anticipated by January 2009, based on the standard review period under the Prescription Drug User Fee Act (PDUFA).
