Summary
This clinical study proposes to evaluate the combination of maraviroc with an integrase strand transfer inhibitor (either raltegravir or dolutegravir) in antiretroviral-experienced patients to document the efficacy, safety, and tolerability of this combination in order to provide clinicians with a treatment regimen that minimizes the risk of metabolic complications by avoidance of NRTI/NNRTIs and PIs. The development of an alternative ART regimen which lessens the risk of metabolic complications could improve long-term adherence and reduce the risk of certain co-morbidities associated with long-term ART use. If this new combination is found to be as efficacious as the standard regimen with enhanced tolerability and improved metabolic effects, there is great potential for altering the current practice of HIV medicine.

Eligibility Criteria
Inclusion Criteria
- HIV-1 infection
- Age between 18 and 75 years
- CD4 count nadir ≥ 250 cells/mm3
- HIV RNA ≤ 50 copies/ml for ≥ 12 months while taking any ART regimen
o One virologic blip ≤ 400 copies/ml permissible within the 12 months
- CCR5 tropic virus as defined by:
- trofile/tropism testing if available, OR
- DNA trofile if no trofile/tropism test available and CD4 nadir 250-499 cells/mm3, OR
- CD4 nadir ≥ 500 cells/mm3
Exclusion Criteria
- Age 75 years
- CD4 count nadir 2.5 times the upper limits of normal
- Women who:
- are currently pregnant or breastfeeding
- are of child-bearing age and do not agree to remain abstinent or use (or have their partner use) an acceptable method of birth control throughout the study. Acceptable method of birth control is defined as intrauterine device (IUD), diaphragm with spermicide, contraceptive sponge, condom, vasectomy.
- History of any malignancy except non-melanoma skin cancer
- Concomitant use of drugs known to impact or be impacted in terms of pharmacokinetics or drug-drug interactions with either raltegravir or maraviroc. This includes:
- Inducers of UGT1A1 (such as rifampin, phenytoin, phenobarbital rifabutin, St. John's wort)
- CYP3A inhibitors (such as ketoconazole, itraconazole, clarithromycin, nefazodone, and telithromycin)
- CYP3A inducers (such as rifampin, carbamazepine, phenobarbital and phenytoin)
- Subject requires or is anticipated to require any of the prohibited medications noted in the protocol
- Enrollment in an experimental protocol having received investigational agents (antiretroviral or non-antiretroviral) within 30 days of study enrollment
- Chronic active hepatitis B infection as defined by presence of HBsAg
- Subject has a history or current evidence of any condition, therapy, laboratory abnormality or other circumstance that might interfere with the patient's participation for the full duration of the study, such that it is not in the best interest of the patient to participate.
- Subject is unlikely to adhere to the study procedures, keep appointments, or is planning to relocate during the study.
