1 A Single-Dose Clinical Trial to Study the Safety, Tolerability, Pharmacokinetics, and Anti-Retroviral Activity of MK-4250 Monotherapy in Anti-Retroviral Therapy (ART)-Naive, HIV-1 Infected Subjects

The study will evaluate the safety, tolerability, pharmacokinetics, and anti-retroviral activity of MK-4250 monotherapy in anti-retroviral therapy (ART)-naïve, HIV-1 infected participants. The primary hypothesis of the study is that at a dose that is sufficiently safe and generally well tolerated, MK-4250 has superior antiretroviral activity compared to a historical placebo, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) (log10 copies/mL) at 168 hours postdose.

2 Efficacy and Safety of a Simplification Strategy Based on Dolutegravir and Darunavir / Cobicistat vs Optimized Treatment in Suppressed HIV-1-infected Patients Carrying Archived Multidrug Resistance Mutations.

The availability of antiretroviral therapy has led to a reduction in morbidity and mortality in patients with chronic HIV infection. The treatment, however, is not free of side effects, has potential interactions with other medications, is expensive and can be complex, especially in those patients who are very experienced and with mutations that give them resistance to multiple drugs. For this reason, the development of simplification strategies that avoid unnecessary exposure to antiretroviral agents remains of great interest. This is a simplification study, in which the investigators try to evaluate that with less medication the investigator can maintain the same virological control of the disease. This would mean a lower burden of medication for patients, facilitating its administration and reducing the number of unwanted side effects. Specifically, the investigators intend to evaluate the treatment with Darunavir / cobicistat plus Dolutegravir as a simplification strategy, since both drugs are taken once a day, have a powerful antiviral activity, even against antiretroviral resistant viruses, and are among the best tolerated (with fewer side effects). The results reported in some observational studies suggest that two-drug therapy (bitherapy) as a simplification strategy could also be safe and effective, however, as far as the investigators know, there are no data and clinical trials that specifically evaluate darunavir / cobicistat plus dolutegravir as a strategy of simplification.
