Zingo™ provides topical, local analgesia to reduce the pain associated with peripheral IV insertions or blood draws, in children three to 18 years of age. Zingo is an easy-to-administer, single-use, needle-free system containing 0.5 mg sterile lidocaine powder. It provides a rapid onset of action, allowing intravenous line placement or venipuncture to begin one to three minutes after administration.
In two pivotal, randomized, double-blind, placebo-controlled, Phase 3 clinical studies, 1,114 patients across 15 U.S. clinical centers received treatment with Zingo or placebo one to three minutes before blood draws or IV line placements at the back of hand or antecubital fossa (crux of the elbow): Zingo demonstrated a statistically significant reduction in procedural pain compared to placebo in children three to 18 years of age. The most common adverse reactions were redness (erythema), red dots (petechiae) and swelling (edema) at the site of administration.
In August 2007, the U.S. Food and Drug Administration (FDA) approved Zingo to reduce the pain associated with peripheral IV insertions or blood draws in children three to 18 years of age.
Initial results of a large randomized, double-blind, placebo-controlled Phase 3 clinical trial, enrolling nearly 700 adult patients, demonstrated that patients undergoing venipuncture or peripheral IV cannulation one to three minutes after treatment with Zingo experienced significantly less pain versus placebo. The incidence of adverse events was no higher in active drug group vs. patients who received placebo. Anesiva expects to file a supplemental new drug application (sNDA) with the FDA to expand Zingo’s label indication to include adults in the first quarter of 2008.
Anesiva plans to market Zingo with a targeted pediatric hospital-based specialty sales force. Zingo will be co-promoted with and distributed by Sagent Pharmaceuticals, Inc.
Among Zingo’s properties:
Rapid onset of analgesia in 1-3 minutes after administration
Incorporate Zingo into the peripheral IV procedure 1-3 minutes prior to needle insertion
Simple to use, easy to administer
Needle-free
In clinical trials, the most common adverse reactions (>5%) were skin reactions at the site of administration: redness (erythema), red dots (petechiae) and swelling (edema)
Zingo Mechanism of Action
Zingo delivers a powder form of lidocaine. Instead of using a needle to deliver the analgesic, Zingo uses compressed gas to accelerate the lidocaine particles into the skin. This provides analgesia in one to three minutes.
Guidelines and recommendations from the American Academy of Pediatrics, the American Pain Society and the Infusion Nurses Society all call for the use of topical anesthetics prior to venous access procedures.
