Rhea-AI Summary

Merck (NYSE: MRK) announced an update on the Phase 2 IMAGINE-DR clinical trial, which evaluated the combination of MK-8507 and islatravir (ISL) for HIV-1 treatment.

Nevertheless, Merck remains committed to advancing islatravir across various settings, continuing other trials without MK-8507.
