Study Summary

The purpose of this study is to evaluate the safety and tolerability of DOR/ISL in adult participants with HIV-1 who had been previously treated with DOR/ISL in earlier clinical studies. There are no formal hypotheses to be tested in this study.

Primary Outcome

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants who experience an AE through Week 96 will be presented.
