简要总结
Background: The primary goal of antiretroviral therapy is to prevent HIV-associated morbidity and mortality. The effectiveness of first-line regimens is supported by a large number of clinical trials; current concerns focus on the long-term adverse effects of antiretrovirals, especially integrase strand transfer inhibitors, as they have been associated with significant weight gain, which may be associated with increased cardiovascular risk.
Objective: To determine the effectiveness, safety, and tolerability of Dolutegravir/Lamivudine (DTG/3TC) compared with Bictegravir/Tenofovir Alafenamide/Emtricitabine (BIC/TAF/FTC) in treatment-naive people living with HIV (PWH). Materials and methods: With prior approval from the Ethics and Scientific Research Committee 3502, an open-label, randomized clinical trial will be conducted at the Infectious Diseases Hospital of the National Medical Center "La Raza" from November 2024 to May 2026. Recently diagnosed PWH with no history of PrEP and/or PeP use, without hospitalization criteria, and without a diagnosis of metabolic syndrome based on ATP-III criteria will be identified. They will be invited to participate in the study and, if they accept, they will sign an informed consent form. They will be randomized to start a BIC/TAF/FTC or DTG/3TC 1:1 regimen. Laboratory studies, vital signs, and somatometry including bioimpedance will be performed at 4, 12, 24, 36, 48, 72, 96, 120, 144 weeks of follow-up; viral load and CD4+ count will be measured at weeks 12, 24, 48, 72, 96, 120, 144 weeks after the start of treatment. Sampling will be non-probabilistic; the distribution will be identified using the Kolmogorov-Smirnoff test, and measures of central tendency and percentages will be expressed. Comparisons will be made using the Mann-Whitney U test. Qualitative data will be analyzed using the x2 or Fisher's exact test. Group analysis will be performed at 12, 24, 48, 96 and 144 weeks using the Wilcoxon test. A P value ≤0.05 with a 95% confidence interval will be considered statistically significant.
详细描述
With prior approval of the protocol by the Local Ethics and Scientific Research Committee 3502, PWH attending the HIV clinic at the Infectious Diseases Hospital who are ART (antiretroviral therapy) naive and meet all the protocol inclusion criteria will be identified. They will be invited to participate in the study protocol, and will sign informed consent during the medical visit. If they accept, they will be explained that they can withdraw from the study whenever they wish. The initial medical interview will then be conducted to assess the sociodemographic, clinical, and comorbid characteristics of the PWH, eating habits, exercise, alcoholism and smoking; in addition, anthropometric measurements will be taken with the 4-point bioimpedance equipment (FitScan segmental body composition monitor C-545F), which expresses weight in kilograms, water in %, muscle in kg, bone in kg, fat in %; waist and hip will be recorded on the data collection sheet. The principal or associate investigator will take measurements in centimeters, in addition to vital signs such as blood pressure, heart rate, respiratory rate, oxygen saturation, prior to entering the study. In addition, in that first consultation, the following will be assessed: Glucose, creatinine, lipid profile, liver function test, complete blood count, viral load, CD4+, hepatitis B virus serology, hepatitis C virus serology, and VDRL. Randomization will be performed using the MEDSHARING digital system for each of the two arms, consisting of DTG/3TC or BIC/FTC/TAF. Follow-up appointments will be held at 4, 12, 24, 36, 48, 72, 96, 120, 144 weeks after randomization with further laboratory studies at baseline and at 4, 12, 24, 36, 48, 72, 96, 120, 144 week. Glucose, creatinine, lipid profile, liver profile, complete blood count, adverse events by organ and system, and DAIDS scale will be assessed at 4, 12, 24, 48, 72, 96, 120, 144 weeks after randomization; HIV-1 viral load and CD4+ count will be assessed at 12, 24, 48, 72, 96, 120 and 144 weeks after study entry.Also, Neuropsychiatric disorders will be assessed with scales for depression, anxiety and insomnia: Hospital Anxiety and Depression Scale (HADS-D, HADS-A), Insomnia Severity Index (ISI), Patient Health Questionnaire (PHQ-9) prior to entering the protocol, at 4, 12, 24, 48 72, 96, 120 and 144 weeks after randomization; satisfaction with the treatment and distress associated with it will be assessed using the HIVTSQ and HIVSDM scales will be measured after 4, 12, 24, 48, 72, 96, 129, 144 weeks after randomization.
Sampling and Sample Calculation Sampling will be simple random sampling (1:1), with participation in the study offered to all ART-naive PWH who meet the selection criteria and sign the informed consent form. For this study, the target sample size was 103 participants per treatment group, based on 80% power, an α level of 2.5%, a non-inferiority margin of -10% for virologic efficacy (non-inferiority is established if the lower bound of the 2-sided 95% CI for the difference in response is greater than -10% between the two groups), and an assumed true response of 93% at week 48 for both treatment groups. Considering a 20% attrition rate, a total of 124 patients (62 PWH in each arm) are planned for enrollment.
Statistical Analysis Data will be described using proportions, frequencies, or percentages for categorical variables and using mean and standard deviation or median and percentile, according to their Kolmogorov-Smirnov distribution, for quantitative variables.
The incidence rate of metabolic syndrome, significant weight gain, dyslipidemia, overweight/obesity, and dyslipidemia will be calculated.
The Chi-square test or Fisher's exact test will be used to determine the relative risk of developing metabolic changes with the factors analyzed.
