STRIBILD (cobicistat)

Cytochrome P450 3A Inhibitors Trial Activity: Declining
Infectious Disease Approved 2012-08-27

STRIBILD is a four-drug fixed-dose combination indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients 12 years of age and older weighing at least 35 kg. It is indicated for patients with no prior antiretroviral treatment history or to replace a current stable regimen in patients who are virologically suppressed (HIV-1 RNA <50 copies/mL) for at least 6 months, have no history of treatment failure, and no known resistance to the individual components of STRIBILD.

How STRIBILD Works

STRIBILD achieves antiretroviral activity through the synergistic effect of three active drugs and one pharmacokinetic enhancer: 1. **Elvitegravir:** An integrase strand transfer inhibitor (INSTI) that prevents the integration of HIV-1 DNA into the host cell genome. 2. **Cobicistat:** A selective CYP3A inhibitor that serves as a pharmacokinetic enhancer ("booster") to increase the systemic exposure of elvitegravir. 3. **Emtricitabine and Tenofovir Disoproxil Fumarate (TDF):** Both are nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) that inhibit HIV-1 reverse transcriptase, leading to DNA chain termination and blocking viral replication.

STRIBILD Boxed Warning

POSTTREATMENT ACUTE EXACERBATION OF HEPATITIS B Severe acute exacerbations of hepatitis B have been reported in patients who are coinfected with HIV-1 and HBV and have discontinued EMTRIVA or VIREAD, which are components of STRIBILD. Hepatic function should be monitored closely, with both clinical and laboratory follow-up for at least several months in patients who are coinfected with HIV-1 and HBV and discontinue STRIBILD. If appropriate, initiation of anti-hepatitis B therapy may be warranted ...

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
