SOUTH SAN FRANCISCO, Calif., March 10 /PRNewswire-FirstCall/ -- Anesiva, Inc. (Nasdaq: ANSV) today announced that the company has submitted a supplemental New Drug Application (sNDA) with the U.S. Food and Drug Administration (FDA) to expand the indication for Zingo to treat the pain associated with peripheral IV insertions and blood draws in adults. Zingo(TM) (lidocaine hydrochloride monohydrate) powder intradermal injection system is already approved by the FDA to provide local analgesia prior to peripheral IV insertions and blood draws in children three to 18 years of age.

The sNDA submission is based on results of a multi-center, randomized, double-blind study in 699 adult patients, which demonstrated less procedural pain associated with blood draws or IV cannulations in those treated with Zingo compared to placebo. Of the study participants, 348 patients received placebo and 345 received Zingo one to three minutes before undergoing medical procedures requiring venipuncture or IV line placement at the back of hand or antecubital fossa (crux of the elbow). The primary endpoint was pain upon needle insertion, utilizing the VAS pain scale. The mean pain score in the Zingo-treated patients was significantly lower than in the placebo group (p = 0.003).

The most common skin assessment findings were redness (erythema), red dots (petechiae) and swelling (edema) at the site of administration. The incidence of adverse events with Zingo was no higher than with placebo.
