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-Naïve, HIV-1 Infected Patients

MK-1439 is a promising NNRTI to be used in combination with other antiretrovirals (ARTs) for the treatment of HIV infection. It is a potent inhibitor of HIV-1 replication in vitro and is active against both wild type virus and most common NNRTI…

A Phase 4 Cross-Sectional Study of Bone Mineral Density in HIV-1 Infected Subjects

To characterize the profile of low BMD in >= 50 years old male HIV-1 infected subjects andpost-menopausal female HIV-1 infected subjects taking TDF-based regimens relative tothose taking non-TDF-based regimens for HIV infection.

An open-label randomised two-year trial comparing two first-line regimens in HIV-infected antiretroviral naïve subjects:
darunavir/r + tenofovir/emtricitabine vs. darunavir/r + raltegravir

Primary objective* To assess the non-inferiority of darunavir/r + raltegravir compared to darunavir/r + tenofovir/emtricitabine as first-line treatment strategies in HIV-1 infected, antiretroviral naïve adults over at least 96 weeks (i.e. to assess…

A Randomized Open Label Study Comparing the Efficacy, Safety, and Tolerability of Oral Administration of Amantadine and Ribavirin with Oseltamivir Versus Oseltamivir to Influenza A Virus Infected Immunocompromised Subjects

Primary: To assess the antiviral efficacy of triple combination antiviral drug (TCAD) therapy(i.e. amantadine and ribavirin co-administered with oseltamivir) compared to oseltamivirmonotherapy in immunocompromised subjects diagnosed with Influenza…

A randomized, multicenter study to assess the efficacy on disease activity on enteric-coated mycophenolate sodium (EC-MPS, myfortic) versus continuation of azathioprine in patients with systemic lupus erythematosus on azathioprine maintenance therapy.

To assess, in patients with systemic lupus erythematosus, the effect on disease activity of a regimen with myfortic® versus continuation of azathioprine.

The influence of Raltegravir (MK_0518) on the pharmacokinetics of single-dose Lamotrigine in healthy male subjects (GRANOLA)

In vitro data indicate that raltegravir is not a substrate of UGT1A4 or UGT2B7, but there is no evidence that raltegravir itself does not influence metabolism of other agents mediated by either UGT1A4 or UGT2B7.

A single-dose, open-label, randomized crossover study to assess the bioequivalence of darunavir 800 mg, emtricitabine 200 mg, and tenofovir alafenamide 10 mg, in the presence of cobicistat 150 mg, administered as either a fixed-dose combination tablet or as separate agents in healthy subjects

The purpose of this study is to evaluate the single dose pharmacokinetics and pivotal bioequivalence of Darunavir (DRV) 800 milligram (mg), Emtricitabine (FTC) 200 mg, and tenofovir alafenamide (TAF) 10 mg when administered as a fixed dose…

Convalescent Antibody-Mediated Treatment of COVID-19 Infections in Patients with B-cell dysfunction, a Randomized Trial (COVID-Compromise Study).

There have been reports of a more serious course of COVID-19 infections in patients with a reduced immune system, such as patients with congenital immune disorders, (haematological) malignancies or patients taking medications that suppress the…

A Phase 1, Single-blind, Randomized, Parallel-group Study in Healthy Participants to Investigate the Single-dose Pharmacokinetics, Safety and Tolerability of Rilpivirine After Subcutaneous Administration of a Rilpivirine Extended-Release Suspension alone, and of Rilpivirine and Cabotegravir After Co-administration with Cabotegravir Extended-Release Suspension

To characterize the single-dose pharmacokinetic (PK) of RPV after SC administration of RPV LA suspensions with different doses and/or different particle size (PS) to support further dose and formulation selection, in healthy adult participants.To…

Primary objectiveTo evaluate current clinical practice and develop a population based Campath® (Alemtuzumab) pharmacokinetics model for predicting total Alemtuzumab exposure after i.v. administration before allogeneic stem cell transplantation in…

Vaccination Against Covid in Primary Immune Deficiencies

To assess immunogenicity and safety of SARS-CoV-2 vaccination in patients with isolated antibody deficiencies, i.e. patients with immunoglobulin G (IgG) subclass deficiency and patients with selective antibody deficiency with normal immunoglobulins…

Switching to Tenofovir Alafenamide Fumarate or ABACavir in patients with Tenofovir Disoproxil Fumarate associated eGFR decline. A randomized clinical trial.

To study the renal safety when HIV patients with TDF related renal toxicity switch to TAF compared to the current practice of switching to ABC.
