Doravirine/islatravir for the treatment of HIV

When approved, doravirine/islatravir should be considered for patients who have previously failed treatment due to viral resistance. It expands the selection of two-drug single-pill therapies and introduces a novel mechanism of action to the market. However, more data is needed regarding the effects of islatravir on CD4 counts. ISL doses as low as 0.25 mg proved non-inferior to current treatments. Therefore, evaluation of the long-term efficacy and safety of DOR/ISL should focus on reduced doses of ISL and minimizing CD4 reduction.
