Real-life outcomes of maraviroc-based regimens in HIV-1-infected individuals

The use of maraviroc in our unit was reviewed with regard to efficacy and safety and also reviewed with regard to how our experience reflects the data presented in clinical trials.

We utilized the pharmacy dispensary system to identify any patient dispensed maraviroc and conducted a case note review.

We identified 27 patients who have been prescribed maraviroc as part of their antiretroviral treatment. In all, 81% were men and 81% were white British. There were 26 treatment-experienced patients and 1 treatment-naive patient. At the time of switching to maraviroc, 17 patients had detectable HIV viral loads and 10 had HIV RNA levels <40 copies/mL. At completion, 6 undetectable patients maintained undetectability and 10 viremically detectable patients achieved viral suppression. Maraviroc was discontinued in 18.5% of patients and the only adverse drug reaction reported was a rash.

The experience of using maraviroc by our study participants shows similarity in terms of efficacy and safety to the MERIT and MOTIVATE clinical trials.
