Dosage form: injectable injection
Drug class: Miscellaneous antivirals
What is Trogarzo?
Trogarzo ((ibalizumab-uiyk) is an antiviral medicine that is used in combination with other antiviral medicines to treat Human Immunodeficiency Virus-1 (HIV-1) infection in adults who:
- have received several anti-HIV-1 regimens in the past, and
- have HIV-1 virus that is resistant to many antiretroviral medicines, and
- who are failing their current antiretroviral therapy.
Trogarzo ((ibalizumab-uiyk) is a recombinant humanized monoclonal antibody that works by binding to domain 2 of CD4 and blocking HIV-1 from infecting CD4+ T cells and preventing the viral transmission that occurs via cell-cell fusion.
HIV-1 is a virus that attacks the body’s immune system. If HIV is not treated, people typically progress through three phases (acute HIV infection, chronic HIV infection, and Acquired Immune Deficiency Syndrome [AIDS]). Untreated, people with AIDS usually only survive about 3 years.
Trogarzo was FDA approved on March 6, 2018.
Warnings
Trogarzo may cause hypersensitivity reactions including infusion-related reactions and anaphylactic reactions. You should not use Trogarzo if you are allergic to ibalizumab. Tell your healthcare provider or nurse, or get medical help right away if you get any of the following symptoms of an allergic reaction, such as:
- trouble breathing
- cough
- swelling in your throat
- hot flush
- wheezing
- nausea
- chest pain
- vomiting
- chest tightness.
Immune Reconstitution Inflammatory Syndrome (IRIS) is a state of hyperinflammatory response that has been reported in patients treated with combination antiretroviral therapies.
Trogarzo may cause irreversible immunosuppression (CD4+ T cell and B cell lymphocytopenia) in infants born to mothers exposed during pregnancy. Your healthcare provider will monitor exposed infants for signs and symptoms of immunosuppression. The safety of administering live or live-attenuated vaccines in exposed infants is unknown.
It is not known if Trogarzo is safe and effective in children.
Before taking this medicine
Before you receive Trogarzo, tell your doctor about all your medical conditions or allergies.
Trogarzo affects your immune system. Tell your doctor if you have signs of a new infection such as fever, night sweats, swollen glands, cough, diarrhea, or weight loss.
Tell your doctor if you are pregnant or become pregnant while taking Trogarzo or any other medications used to treat HIV. Continue taking your medications throughout pregnancy. HIV can be passed to your baby if the virus is not controlled during pregnancy. Your name may be listed on a registry to track any effects of antiviral medicine on the baby.
Women with HIV or AIDS should not breastfeed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
How is Trogarzo administered?
Trogarzo is administered by your healthcare provider as an intravenous infusion (IV infusion) or as an intravenous push (IV push).
- The first dose will be given over 30 minutes by IV infusion or 90 seconds by IV push.
- After the first dose, the dose will be given over 15 minutes by IV infusion or 30 seconds by IV push.
A healthcare provider will monitor you during the infusion or IV push and for some time afterward.
- You will receive Trogarzo every two weeks.
- Ensure you keep your appointments every two weeks as instructed by your healthcare provider. Do not change the schedule of your IV infusion/IV push, or any of your antiretroviral medicines without talking to your healthcare provider first.
HIV is often treated with a combination of drugs. Use all medications as directed and read all medication guides you receive. Every person with HIV should remain under the care of a doctor.
