How does this medicine work?[edit | edit source]

Ibalizumab-uiyk, a recombinant humanized monoclonal antibody, blocks HIV-1 from infecting CD4+ T cells by binding to domain 2 of CD4 and interfering with post-attachment steps required for the entry of HIV-1 virus particles into host cells and preventing the viral transmission that occurs via cell-cell fusion.

Can this medicine be used in pregnancy?[edit | edit source]

Based on animal data, ibalizumab-uiyk use during pregnancy may cause reversible immunosuppression (CD4+ T cell and B cell lymphocytopenia) in infants exposed to ibalizumab-uiyk in utero. Immunoglobulin G (IgG) antibodies, such as ibalizumab-uiyk, are transported across the placenta in significant amounts, especially near term; therefore, ibalizumab-uiyk has the potential to be transferred from the mother to the developing fetus (see Clinical Considerations). There are no available data on ibalizumab-uiyk use in pregnant women to evaluate for a drug- associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

Can this medicine be used in children?[edit | edit source]

The safety and effectiveness of TROGARZO in pediatric patients have not been established.

What should I know about storage and disposal of this medication?[edit | edit source]

Store vials under refrigeration at 2 to 8ºC (36-46 ºF). Do not freeze and protect from light.
Once diluted, the TROGARZO solution should be administered immediately
