Registration Number
NCT05295394
Lead Sponsor
Pedro Cahn
Brief Summary

The purpose of this study is to evaluate the antiviral efficacy, safety and tolerability of dual therapy with 3TC and DTG as initial therapy among naïve HIV patients with a documented M184V mutation.

Detailed Description

This is a pilot study designed to evaluate the antiviral efficacy, safety and tolerability of dual therapy with 3TC and DTG as initial therapy among naïve HIV-1 subjects ≥ 18 years old carrying the M184V mutation

This will be evaluated as the proportion of patients with pVL \< 50 copies/mL at week 48 using the ITT-exposed analysis (FDA snaphot).

This study will consist of a screening period of up to 42 days, a 48-week treatment period, followed by a 4-week post-treatment follow-up (FU) period to document late adverse events.

The study will include 20 HIV-1-infected subjects, meeting all inclusion criteria and not meeting any exclusion criteria for this study.

Exclusion Criteria

Patients will NOT be selected to be part of this study if they meet ANY of the following criteria:

  • Alcohol or drug use that might impact on adherence
  • Subjects positive for Hepatitis B at screening (+HBsAg), or anticipated need for Hepatitis C virus (HCV) therapy during the study
  • Women who are pregnant or breastfeeding, or women who plan to become pregnant in the next 2 years
  • interferon, interleukin-2, cytotoxic chemotherapy, Dofetilide (or pilsicainide) or immunosuppressors, antacid drugs containing Ca++ and or Mg++ at study entry
  • Grade 4 lab abnormalities
  • Primary HIV infection (indeterminate WB or previous negative HIV in the last 6 months
  • Opportunistic infection (CDC C category) or other disease and/or clinical condition that, in the investigator's opinion, would compromise the patient's safety or outcome of the study; including malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma, or cervical intraepithelial neoplasia
  • Subjects who in the investigator's judgment, poses a significant suicidality risk.
  • History or presence of allergy to the study drugs or their components or drugs of their class
  • Treatment with any of the following agents within 28 days of screening: radiation therapy; cytotoxic chemotherapeutic agents; any immunomodulators that alter immune responses or treatment with an HIV-1 immunotherapeutic vaccine within 90 days of screening or exposure to an experimental drug or experimental vaccine within either 28 days, 5 half-lives of the test agent, or twice the duration of the biological effect of the test agent, whichever is longer, prior to the first dose of investigational product
  • Any acute laboratory abnormality at screening, which, in the opinion of the Investigator, would preclude the subject's participation in the study of an investigational compound;
  • Alanine aminotransferase (ALT) >5 times the upper limit of normal (ULN), or ALT ≥ 3xULN and bilirubin ≥ 1.5xULN (with >35% direct bilirubin)
  • Creatinine clearance of <50mL/min via Cockroft-Gault method
  • Subjects with moderate to severe hepatic impairment (Class B or greater) as determined by Child-Pugh classification

Primary Outcome Measures
NameTimeMethod
HIV viral load efficacy at week 4848 weeks

the proportion of patients with pVL \< 50 copies/mL at week 48 using the ITT-exposed analysis (FDA snaphot).

Secondary Outcome Measures
NameTimeMethod
adverse eventsbaseline to 48 weeks

To describe frequency, type and severity of clinical and laboratory adverse events based on DAIDS Adverse event grading table , version 2.1

HIV viral resistance mutationsAt week 48

the number and the type of HIV resistance mutations among patients that meet the definition of virologic failure .

HIV viral load efficacy at week 24week 24 and week 36

proportion of patients with \<400 copies/mL and \<50 copies/mL at weeks 24 and 36.

immunological response in CD4 cell countbaseline and week 48

to measure and compare the absolute values of cd4 cells count in two points, at baseline visit and week 48, in this way we will evaluate the gain or increase of CD4 count cells during the study.

lipid profile changebaseline and week 48

to measure the change in cholesterol and triglyceride values. we are going to compare the value at the baseline visit and at week 48 for both deteminations, in this way we will evaluate the response or change on the lipid profile.
