Study of ALGRX 3268 for Needlestick Pain in Children

Inclusion Criteria:

• Outpatient children of either gender who were to undergo venipuncture at the back of the hand
• Children must have had sufficient cognitive skills to identify faces depicting extremes of pain on the Wong-Baker FACES Pain Rating Scale (ages 3-12) and/or the extremes of pain on a 100 mm VAS (ages 8-18).
• Ages 3 to 7 years; 8 to 12 years; and 13 to 18 years, inclusive
• Consent forms must have been approved by the appropriate Institutional Review Board (IRB). Signed informed consent must have been granted by the parent or legal guardian and assent to participate should have been sought (either verbally or in writing) from each child.
• In females of childbearing potential, who in the judgment of the investigator or designee were sexually active, a negative urine pregnancy test must have been documented prior to enrollment. A negative urine pregnancy test was required in all teenage girls over the age of 14 years. Surgically sterile females did not require a pregnancy test.

Exclusion Criteria:

• Previous history of allergic reactions to any local anesthetic
• Any medical condition or instability that, in the judgment of the investigator, might have adversely impacted the conduct of the study and the collection of data
• Subjects in whom the investigator determined that venipuncture could not be accomplished cleanly
• Active local infection or other skin pathology on the dorsum of the hand
• Subjects with tattoos, surgical scars, ports, implantable devices or a skin condition that may have interfered with placement of study treatment or skin site assessments
• Female subjects who were pregnant or lactating; females who planned to become pregnant; females with a positive serum or urine pregnancy test; females of childbearing potential who were not using adequate contraception.
• Prior participation in an ALGRX 3268 study
• Venipuncture at the proposed site within the prior two weeks (longer if bruising was apparent)
