KALETRA (lopinavir)

HIV Protease Inhibitors Trial Activity: Declining 1 active trials
Infectious Disease Approved 2000-09-15

Kaletra helps patients with HIV-1 infection, including adults and infants at least 14 days old. It is used as part of a combination therapy with other antiretroviral medications to manage the virus. Healthcare providers typically use resistance testing or a patient's medical history to determine if this specific medication is the right choice for their viral profile.

How KALETRA Works

This medication works by combining lopinavir, a protease inhibitor, with ritonavir. Ritonavir acts as an inhibitor of the CYP3A enzyme, which prevents the body from breaking down lopinavir too quickly. This process maintains higher levels of lopinavir in the blood to help manage the infection.

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
