Evaluation of the Safety and Efficacy of Reformulated Raltegravir (MK-0518) 1200 mg Once Daily in Combination With TRUVADA™ in Human Immunodeficiency Virus (HIV)-1 Infected, Treatment-Naive Participants (MK-0518-292) (onceMRK)

11 januari 2019 uppdaterad av: Merck Sharp & Dohme LLC

A Phase III Multicenter, Double-Blind, Randomized, Active Comparator-Controlled Clinical Trial to Evaluate the Safety and Efficacy of Reformulated Raltegravir 1200 mg Once Daily Versus Raltegravir 400 mg Twice Daily, Each in Combination With TRUVADA™, in Treatment-Naïve HIV-1 Infected Subjects

To evaluate the safety and efficacy of reformulated raltegravir (MK-0518) 1200 mg once daily in combination with TRUVADA™ versus raltegravir 400 mg twice daily in combination with TRUVADA™ in HIV-1 infected, treatment-naive participants. The primary hypothesis being tested is that reformulated raltegravir 1200 mg once-daily is non-inferior to raltegravir 400 mg twice-daily, each in combination therapy with TRUVADA™, as assessed by the proportion of participants achieving HIV-1 ribonucleic acid (RNA) <40 copies/mL at Week 48.

Tidsram
Percentage of Participants Achieving <40 Copies/mL Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) at Week 48
Tidsram: Week 48
From blood samples collected at week 48, HIV-1 RNA levels were determined by the Abbott RealTime HIV-1 Assay, which has a limit of reliable quantification (LoQ) of 40 copies/mL. The NC=F approach as defined by FDA "snapshot" approach was used as the primary approach to analysis where all missing data were treated as failures regardless of the reason.

Percentage of Participants With an Adverse Event (AE) at Week 48
Tidsram: Up to Week 48
An adverse event (AE) is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Up to Week 48
Percentage of Participants With an AE After 96 Weeks of Treatment
