APRETUDE vs EMZAHH
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Apretude (cabotegravir) is an HIV-1 integrase strand transfer inhibitor (INSTI) that inhibits the integration of HIV-1 DNA into host genomic DNA, which is essential for viral replication. It binds to the active site of integrase and blocks the strand transfer step of retroviral DNA integration.
EMZAHH is a monoclonal antibody that targets and binds to the human epidermal growth factor receptor 2 (HER2), inhibiting downstream signaling pathways involved in cell proliferation and survival.
600 mg IM every 2 months, initiated as two consecutive monthly loading doses of 600 mg each, for HIV-1 pre-exposure prophylaxis.
10 mg orally twice daily without regard to meals.
