1. At least 18 years of age on the day of signing the informed consent.
2. Understand the study procedures and voluntarily agree to participate by giving written informed consent (or have a legal representative provide written informed consent, if considered acceptable by local regulatory agencies and/or ERCs/IRBs) for the trial. The subject or his/her legal representative (if considered acceptable by local regulatory agencies and/or ERCs/IRBs) may also provide consent for Future Biomedical Research. However, the subject may participate in the main trial without participating in Future Biomedical Research.
3. Have had documentation of HIV-1 RNA < 50 copies/mL for at least 12 weeks prior to screening while on ATRIPLATM.
4. Have plasma HIV-1 RNA levels BLoQ (<40copies/mL) at the screening visit.
5. If genotyping was performed at any point prior to screening and results are available, the subject must have no known resistance mutations to any of the study agent components.
6. have at least one EFV-associated CNS toxicity of Grade 2 or worse intensity both at the time of screening and at Study Day 1 (BL); at least one of the Grade 2 or worse intensity CNS toxicity present at screening must also be present at Study day 1 with Grade 2 or worse intensity.
EFV associated CNS toxicity is defined as one of the following conditions listed on the CNS toxicity questionnaire: dizziness, depression/low mood, insomnia/sleeplessness, anxiety/nervousness, confusion, impaired concentration/attention, headache, somnolence/daytime sleepiness, aggressive mood/behavior, abnormal dreams.
7. have the following laboratory values at screening :
a) Alkaline phosphatase = 3.0 x upper limit of normal (ULN) 0 b) AST (SGOT) and ALT (SGPT) = 5.0 x ULN
c) Hemoglobin =9.0 g/dL (if female) or =10.0 g/dL (if male).
8. Calculated creatinine clearance = 50mL/min
9. In the opinion of the investigator, be considered clinically stable with no signs or symptoms of active infection at the time of entry into the study (i.e., clinical status and all chronic medications should be unchanged for at least 2 weeks prior to the start of treatment in this study).
10. be highly unlikely to become pregnant or to impregnate a partner
Study Extension 1 Eligibility:
11. have completed the Study Week 24 (for ISG) or Study Week 36 (for
DSG) visit.
12. be considered, in the opinion of the investigator, to have derived benefit from study participation through Study Week 24 (for ISG) or Study Week 36 (for DSG).
13. be considered, in the opinion of the investigator, a clinically appropriate candidate for an additional 2 years (additional 96 weeks) of treatment with MK-1439A.
14. understand the procedures in the study extension 1 and provide written informed consent to enter the study extension 1, thus continuing for approximately 2 years (96 weeks) beyond the base study.
Study Extension 2 Eligibility:
15. have completed the Study Week 120 (for ISG) or Study Week 132 (for DSG) visit.
16. be considered, in the opinion of the investigator, to have derived benefit from MK-1439A by Study Week 120 (for ISG) or Study Week 132 (for DSG).
17. be considered, in the opinion of the investigator, a clinically appropriate candidate for an additional 2 years (additional 96 weeks) of treatment with MK-1439A.
18. understand the procedures in the study extension and provide written informed consent to enter study extension 2, thus continuing treatment with MK-1439A until it is locally available or for up to approxim
1. has a history or current evidence of any condition, therapy, laboratory abnormality or other circumstance that might confound the results of the study or interfere with the subject's participation for the full duration of the study, such that it is not in the best interest of the subject to participate.
2. is, at the time of signing informed consent, a user of recreational or illicit drugs or has had a recent history of drug or alcohol abuse or dependence. The nature and potential clinical context of the subject's illicit drug use, in relation to their exclusion from this trial, will be at the discretion of the Investigator.
3. has ongoing Grade 4 CNS toxicity during screening period that requires a prompt change in ART.
4. has been treated for a viral infection other than HIV-1, such as hepatitis B, with an agent that is active against HIV-1 including, but not limited to, adefovir, emtricitabine, entecavir, lamivudine or tenofovir.
5. has documented or known resistance to study drugs including MK-
1439, EFV (Efavirenz), lamivudine, emtricitabine and/or tenofovir
(based on genotyping performed prior to the initiation of treatment with
ATRIPLATM) as defined below:
a. Resistance to MK-1439 or Efavirenz for the purpose of this study includes the following NNRTI mutations: L100I, K101E, K101P, K103N, K103S, V106A, V106I, V106M, V108I, E138A, E138G, E138K, E138Q, E138R, V179L, Y181C, Y181I, Y181V, Y188C, Y188H, Y188L, G190A, G190S, H221Y, L234I, P225H, F227C, F227L, F227V, M230L, M230I
b. Resistance to lamivudine, emtricitabine and tenofovir includes the following mutations: K65R, M41L, T69S (insertion complex), Q151M, M184I, M184V, L210W, T215F, T215Y, K219E, K219Q, D67N, K70R, K70E.
6. has participated in a study with an investigational compound/device within 30 days prior to signing informed consent or anticipates participating in such a study involving an investigational compound/device during the course of this study.
7. has used systemic immunosuppressive therapy or immune modulators within 30 days prior to treatment in this study or is anticipated to need them during the course of the study.
Note: Short courses of corticosteroids (e.g., as for asthma exacerbation)
