About this trial
This study will compare the safety and effectiveness(Of a drug or treatment). The maximum ability of a drug or treatment to produce a result regardless of dosage. A drug passes efficacy trials if it is effective at the dose tested and against the illness for which it is prescribed. In the standard procedure, Phase II clinical trials gauge efficacy, and Phase III trials confirm it. of using a lower dose of efavirenz - 400mg versus the standard 600mg dose currently prescribed.
Participants will be randomisedA method based on chance by which study participants are assigned to a treatment group. Randomization minimizes the differences among groups by equally distributing people with particular characteristics among all the trial arms. The researchers do not know which treatment is better. From what is known at the time, any one of the treatments chosen could be of benefit to the participant to receive either dose along with Truvada (tenofovir + emtricitabine) and be followed for 96 weeks.
Participants will have an equal (1:1) chance of receiving either regimen. This is a double-blindA clinical trial design in which neither the participating individuals nor the study staff knows which participants are receiving the experimental drug and which are receiving a placebo (or another therapy). Double-blind trials are thought to produce objective results, since the expectations of the doctor and the participant about the experimental drug do not affect the outcome; also called double-masked study. study so neither participant nor the doctor will be aware of which treatment participants receive.
Background information
There's evidence to suggest that several antiretroviralsA medication or other substance which is active against retroviruses such as HIV. might be just as effective when taken in doses lower than they're currently prescribed. Potentially, this could mean paying less for fewer pills with not as many side effects or toxicities.
This is one of several trials looking at finding the optimum dose of various antiretrovirals. Other trials will be looking at ritonavir, ritonavir-boosted lopinavir, ritonavir-boosted atazanavir, and zidovudine.
