Ibalizumab-uiyk is an HIV entry or fusion inhibitor.

Cautions for Ibalizumab-uiyk

Contraindications

None.1

Warnings/Precautions

Immune Reconstitution Inflammatory Syndrome

Immune reconstitution inflammatory syndrome has been reported in one patient treated with ibalizumab-uiyk in combination with other antiretrovirals. During the initial phase of combination antiretroviral therapies, patients whose immune systems respond may develop an inflammatory response to indolent or residual opportunistic infections, which may necessitate further evaluation and treatment.1

Specific Populations

Pregnancy

There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ibalizumab-uiyk during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1–800–258–4263.1

No adequate human data are available to establish whether or not ibalizumab-uiyk poses a risk to pregnancy outcomes. Animal reproductive toxicology studies with ibalizumab-uiyk have not been conducted. Monoclonal antibodies, such as ibalizumab-uiyk, are transported across the placenta as pregnancy progresses; therefore, ibalizumab-uiyk has the potential to be transmitted from the mother to the developing fetus. 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. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.1

Lactation

The Centers for Disease Control and Prevention recommend that HIV-1-infected mothers in the United States not breastfeed their infants to avoid the risk of postnatal transmission of HIV-1 infection.1

No data are available regarding the presence of ibalizumab-uiyk in human milk, the effects on the breastfed child, or the effects on milk production. Human IgG is present in human milk, although published data indicate that antibodies in breast milk do not enter the neonatal or infant circulation system in substantial amounts. Because of the potential for HIV-1 transmission, instruct mothers not to breastfeed if they are receiving ibalizumab-uiyk.1

Pediatric Use

The safety and effectiveness of ibalizumab-uiyk in pediatric patients have not been established. 1

Geriatric Use

No studies have been conducted with ibalizumab-uiyk in geriatric patients. 1

Common Adverse Effects

Adverse Reactions

The most common adverse reactions (incidence ≥ 5%) were diarrhea, dizziness, nausea, and rash. 1
