Primary outcomePrimary: Percentage of Participants With At Least 1 AE in Weeks 0-24: Doravirine (All Doses) vs Efavirenz (Part I) — 90.0; 93.0; 71.4; 85.4 Percentage of participants
Summary
The hypothesis tested in this study is that doravirine (MK-1439) at the final dose selected is superior to efavirenz, each given in combination with TRUVADA®, as measured by the percentage of participants with CNS events by Week 8. If superiority is established at Week 8, the same hypothesis will be tested for Week 24.
