            Pregnancy Categories

            A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            Pharmacology

            Mechanism of Action

            Recombinant dimeric fusion protein: extracellular CD2-binding portion of human leukocyte function antigen-3 (LFA-3) linked to the Fc portion of human IgG1

            Inhibits LFA-3/CD2 interaction, thus inhibits T lymphocyte activation (decreases CD45RO+ T lymphs)

            Absorption

            Bioavailability: 63% (IM)

            Distribution

            Vd: 94 mL/kg (IV)

            Elimination

            Half-Life: 270 hr (IV)

            Clearance: 0.25 mL/kg/hr (IV)
