The Student\'s t-test or the Mann-Whitney U-test will be used for data from independent groups according to their distribution.\n\nSubject to prior approval of the protocol by the local scientific research ethics committee and the relevant agencies, patients being monitored at the HIV clinic at the Infectious Diseases Hospital of the CMN "La Raza" who are living with HIV and receiving treatment with DRV/c + TFV/FTC for virological suppression will be identified as candidates for participation in the study.\n\nThey will be invited to participate in the study protocol, and the project and its likely outcomes will be explained in detail to the subjects. It will be explained that treatment assignment will be randomized using the digital system (MEDSHARING: randomizer for clinical trials) to one of two arms:\n\n1. DRV/c (800 mg/150 mg once daily) + 3TC (300 mg once daily) or\n2. DRV/c (800 mg/150 mg once daily) + TFV/FTC (300 mg/200 mg once daily). Answers will be obtained during the medical interview, allowing the patient to freely decide whether to continue or withdraw from the study during the study period without affecting their medical care at the HIV clinic. Informed consent will be obtained, and to maintain privacy, a patient ID number will be assigned at the time of recruitment. Weight (kg), height (cm), body mass index (BMI) (kg/height (m2), body composition (fat, water, muscle, kg, bone, kg) will be measured using the FitScan BC-545F segmental body composition monitor, and waist and hip measurements will be measured using a tape measure. Laboratory studies will include a complete blood count, complete blood chemistry with glucose and creatinine, a complete lipid profile, and post-randomization liver function tests at 4 weeks, 12 weeks, 24 weeks, and 48 weeks post-switch. CD4+ and HIV-1 RNA determinations will be performed prior to randomization, and at 3 months, 6 months, and 12 months post-study entry. Comparisons will be made between measurements taken prior to entry, 24 weeks, and 48 weeks post-study entry. Serum electrolytes (phosphorus, magnesium, calcium), cystatin C, and urinary electrolytes (phosphorus, magnesium, calcium, creatinine, urea, microproteins) will be measured prior to randomization and at 24 and 48 weeks post-switch.\n\nIf patients present with elevated AST and/or ALT \\>90 IU/L, serology tests will be ordered to rule out HBV and HCV.\n\nThe ISI, PHQ-9, HADS-A, and HADS-D questionnaires will be administered to assess anxiety, depression, and sleep quality. Additionally, the HIVTSQ questionnaire will be administered to assess treatment satisfaction at weeks 4, 12, 24, and 48 weeks post-randomization, and the HIV-SDM questionnaire will be administered to assess HIV-related symptoms and distress. At each medical visit, potential drug-related adverse effects will be deliberately inquired about by device and system, and will be classified into four grades using the DAIDS adverse event scale.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Men with HIV infection who are virologically suppressed with DRV/c (800 mg/150 mg) + TFV/FTC (300 mg/200 mg) for at least 6 months\n* Age ≥18 years-70 years\n* eGFR ≥30 mL/min\n* Written informed consent\n* Beneficiaries of the Mexican Social Security Institute treated at the Infectious Diseases Hospital of the La Raza National Medical Center.\n\nExclusion Criteria:\n\n* Withdrawal of informed consent\n* Loss of medical insurance\n* Presence of tuberculosis or other opportunistic infection requiring adjustment of the ARV regimen\n* Incomplete data collected during visits Uncontrolled chronic gastrointestinal conditions Desire to be on a single-dose regimen Coinfection with hepatitis B virus during follow-up if in the DRV/3TC arm Coinfection with hepatitis C virus during follow-up'}, 'identificationModule': {'nctId': 'NCT06907056', 'acronym': 'TLALOC', 'briefTitle': 'Effectiveness and Safety of Darunavir/Cobicistat Plus Lamivudine Versus Darunavir/Cobicistat Plus Tenofovir/Emtricitabine in Virologically Suppressed HIV-1-positive Individuals in Mexico', 'organization': {'class': 'OTHER_GOV', 'fullName': 'Instituto Mexicano del Seguro Social'}, 'officialTitle': 'Effectiveness, Safety, and Tolerability of Darunavir/Cobicistat Plus Lamivudine Versus Darunavir/Cobicistat Plus Tenofovir/Emtricitabine in Virologically Suppressed HIV-1-positive Individuals: 48-week Follow-up in Mexico', 'orgStudyIdInfo': {'id': 'R-2024-3502-116'}, 'secondaryIdInfos': [{'id': 'R-2024-3502-116', 'type': 'OTHER', 'domain': 'Instituto Mexicano Del Seguro Social'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Standar therapy', 'description': 'Darunavir/cobicistat 800/150 mg + tenofovir/emtricitabin 300/200 mg This arm is the commonly used therapy or standard 3-drug therapy consisting of Darunavir/cobicistad 800/150 mg, plus tenofovir/emtricitabine 300/200 mg', 'interventionNames': ['Drug: Standard Medical Therapy']}, {'type': 'EXPERIMENTAL', 'label': 'Dual therapy', 'description': 'Darunavir/cobicistat 800/150 mg + lamivudine 300 mg This arm is the experimental one, with dual therapy, 2 drugs: darunavir/cobicistat 800/150 mg plus lamivudine 300 mg', 'interventionNames': ['Drug: dual therapy']}], 'interventions': [{'name': 'dual therapy', 'type': 'DRUG', 'otherNames': ['DRV/c+3TC'], 'description': 'Intervention arm will be dual therapy oh DRV/C 800/150 mg + 3TC 300 mg, this will be compared to standar therapy of 3 drugs with: DRV/c 800/150 mg + TDF/FTC 300/200 mg', 'armGroupLabels': ['Dual therapy']}, {'name': 'Standard Medical Therapy', 'type': 'DRUG', 'otherNames': ['DRV/c+TDF/FTC'], 'description': 'DRV/c+TDF/FTC', 'armGroupLabels': ['Standar therapy']}]}, 'contactsLocationsModule': {'locations': [{'zip': '02990', 'city': 'Mexico City', 'state': 'Mexico City', 'status': 'RECRUITING', 'country': 'Mexico', 'contacts': [{'name': 'Ana Cano, Posgraduated', 'role': 'CONTACT', 'email': 'ana.knodiaz@gmail.com', 'phone': '2291243665'}, {'name': 'José A Mata, Master degree', 'role': 'CONTACT', 'email': 'jamatamarin@gmail.com'}, {'name': 'José A Mata, Master degree', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Ana L Cano, postgraduate', 'role': 'SUB_INVESTIGATOR'}], 'facility': 'Hospital de Infectología, Centro Médico Nacional La Raza', 'geoPoint': {'lat': 19.42847, 'lon': -99.12766}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': 'The data cannot be shared openly because it contains personal information about the participants; if required, it can be requested from the corresponding author.'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'José Antonio Mata Marín', 'class': 'OTHER_GOV'}, 'responsibleParty': {'type': 'SPONSOR_INVESTIGATOR', 'investigatorTitle': 'Doctor', 'investigatorFullName': 'José Antonio Mata Marín', 'investigatorAffiliation': 'Instituto Mexicano del Seguro Social'}}}}
