Multicenter, Double-Blind, Randomized, 2-Part, Dose Ranging Study to Compare the Safety, and Antiretroviral Activity of MK-1439 Plus TRUVADA Versus Efavirenz Plus TRUVADA in Antiretroviral Treatment-Naive, HIV-1 Infected Patients

Part 1 - Dose-Ranging. Part 1 will evaluate the (1) safety and tolerability and (2) efficacy
(antiretroviral activity) of 4 doses of MK-1439 compared with efavirenz, when each is given
in combination with TRUVADA® for at least 24 weeks in approximately 200 participants. A
single dose of MK-1439 will be selected for further study after all participants complete
the Week 24 visit in Part 1. Participants receiving any dose of MK-1439 in Part 1 will be
switched to the selected MK-1439 dose and continue in the study for up to 96 weeks.

Part 2 - Selected Dose. Part 2 will be initiated after the MK-1439 dose has been selected as
indicated above for Part 1. Approximately 120 additional participants will be randomized in
1:1 ratio to the selected dose of MK-1439 or efavirenz, each in combination with TRUVADA®
for 96 weeks of blinded treatment. Part 2 will evaluate the safety of the selected dose
compared with efavirenz, particularly with regard to central nervous system adverse events
(CNS events).

The hypothesis tested in this study is that MK-1439 at the final dose selected is superior
to efavirenz, each given in combination with TRUVADA®, as measured by the proportion of
participants with CNS events by Week 8. If superiority is established at Week 8, the same
hypothesis will be tested for Week 24.
