Trogarzo is indicated for the treatment of HIV-1 infection in heavily treatment-experienced adults with multidrug-resistant HIV-1 who are failing their current antiretroviral regimen.
Trogarzo is a monoclonal antibody that binds to the CD4 receptor on T-helper cells, blocking HIV from entering and infecting these immune cells. It is a CD4-directed post-attachment inhibitor that works synergistically with other antiretroviral drugs.
Trogarzo is administered as an intravenous infusion by a healthcare provider every two weeks after an initial loading dose. Common side effects may include diarrhea, dizziness, nausea, and rash. Patients should be monitored for immune reconstitution inflammatory syndrome. It must be used in combination with other antiretroviral medications as part of an optimized background regimen.
