Head-to-head evidence
Alimatravir vs Rilpivirine
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

Alimatravir
Developed by Merck & Co.
NCT06045507 · Phase 2 · completed
The study randomized 352 participants to three MK-8527 dose groups or matched placebo and used double blinding, but Alimatravir was not studied and was not the comparator. Its primary endpoints were safety outcomes rather than efficacy, and the registry provides counts without statistical comparisons, so whether the primary comparisons were met cannot be determined.
Next expected readout: January 2027 · NCT07600775 (registry estimate)
Rilpivirine · Edurant
Marketed by Johnson & Johnson and partners
NCT00540449 · Phase 3 · completed
This was a large (690-participant), randomized, quadruple-blinded, active-controlled (efavirenz) phase 3 trial with a hard clinical endpoint (confirmed viral load <50 copies/mL). The pre-specified non-inferiority margin was clearly met, with the confidence interval for the treatment difference falling entirely within the allowed -12% boundary, so rilpivirine was shown to be as effective as efavirenz on the primary measure despite a somewhat higher rate of virologic failure and resistance emergence as a secondary finding.
Next expected readout: October 2026 · NCT05660980 (registry estimate)
