The TEddI study is a randomised, multi-centre, open-label study in well-controlled treatment-experienced HIV-infected patients to assess compliance with a once-daily regimen of antiretroviral therapy versus continuation of current anti-retroviral regimen delivered at least twice daily.', 'detailedDescription': "Rationale: 'TEddI' will enable a once-daily treatment strategy to be studied and provide information on effectiveness, patient adherence and quality of life and the tolerability of such regimens.\n\nHypothesis: The study hypothesis is that an antiretroviral regimen comprising of three agents taken once daily will have higher levels of adherence than a regimen requiring more frequent dosing.\n\nPrimary objective: To determine over 24 weeks the levels of adherence in two groups of HIV-infected subjects randomised to receive either a once daily minimum 3-drug regimen or to continue a minimum 3-drug regimen requiring more frequent dosing.\n\nSecondary objectives: The secondary objectives of the study will include:\n\n* To estimate the proportion of patients with treatment failure where treatment failure is defined as:\n* HIV-1 RNA viral load of \\>400 copies/ml on two consecutive occasions more than one month apart, OR\n* Discontinuation of treatment for any reason (where subsequent therapy does not comply with the study regimen change guidelines outlined in section 3.3.3)\n* Proportion of patients with plasma HIV-RNA less than 50 copies/ml (using an ultrasensitive assay) at 24 and 48 weeks\n* Change from baseline in CD4 cell count at 24 and 48 weeks\n* Changes from baseline in subjects' quality of life at 24 and 48 weeks\n* Changes from baseline based on DASS 21 scores at 24 and 48 weeks\n* Incidence and severity of adverse events and abnormal laboratory values (grade 3 \\& 4) at 24 and 48 weeks\n* Proportion of patients remaining on assigned treatment Study Design This is a randomised, open-label, multi-centre, prospective, 48-week study comparing a 3 (or more) drug once-daily antiretroviral regimen with any 3 (or more) drug regimen in which at least 1 drug must be taken at least twice daily.\n\nOne hundred and twenty (120) subjects will be recruited and randomised in a 1:1 ratio to one of two open-label treatment regimens and will continue to receive randomised treatment until week 24:\n\nArm 1: (Once daily arm) commence treatment with a once-a-day combination of licensed antiviral medications (such as EFV/ddI/3TC, EFV/3TC/TDF or ATV/3TC/TDF).\n\nArm 2: (Continuation arm) continue current ART (minimum 3-drugs) dosed twice daily or more frequently\n\nFollowing week 24, patients will have the option to continue randomised treatment for a further 24 weeks or switch to the once daily treatment arm. In all cases, patients will be followed up for 48 weeks from the baseline visit."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* aged 18 years or more with laboratory evidence of HIV-1 infection\n* ability to understand and provide written informed consent to participate in the study\n* stable on current ART regimen for at least 3 months prior to screening.\n* plasma HIV-RNA less than 400 copies/ml at the screening visit.\n* women of child bearing potential must have a negative serum or urine β-HCG pregnancy test within 14 days prior to week -4 (assessment of study eligibility)\n\nExclusion Criteria:\n\n* virological failure of a proposed Once daily arm medication\n* a serious medical condition which may compromise the subject's safety, including an active AIDS-defining condition within the previous 6 months\n* known toxicities to any of the proposed Once daily arm medications\n* laboratory abnormalities at screening:\n* serum creatinine greater than twice the upper limit of normal (2 x upper limit of normal (ULN))\n* AST, ALT or alkaline phosphatase greater than 5 times the ULN\n* lactate greater than 2.5 x ULN\n* haemoglobin less than 9.5 g/dL\n* women who are pregnant or breast-feeding or who, if of child-bearing potential, are not willing to use adequate contraception (including barrier contraception)\n* patients who in the investigator's opinion are unlikely to complete the study"}, 'identificationModule': {'nctId': 'NCT00214435', 'briefTitle': 'Once Daily 3TC, Efavirenz and ddI for HIV Infection', 'organization': {'class': 'OTHER', 'fullName': '407 Doctors'}, 'officialTitle': 'A Randomised, Multi-Centre, Open-Label Study in Well-Controlled Treatment-Experienced HIV-Infected Patients to Assess Compliance With a Once-Daily Regimen of Lamivudine, Efavirenz and Didanosine Versus Continuation of Current Anti-Retroviral Regimen Delivered at Least Twice Daily', 'orgStudyIdInfo': {'id': 'TEddI'}}, 'armsInterventionsModule': {'interventions': [{'name': 'once daily minimum 3-drug regimen of anti-retroviral medications', 'type': 'DRUG'}]}, 'contactsLocationsModule': {'locations': [{'zip': '2010', 'city': 'Sydney', 'state': 'New South Wales', 'status': 'RECRUITING', 'country': 'Australia', 'contacts': [{'name': 'David A Baker, MB ChB', 'role': 'CONTACT', 'email': 'db@407.com.au', 'phone': '02 9332 2531'}, {'name': 'David A Baker, MB ChB', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': '407 Doctors', 'geoPoint': {'lat': -33.86785, 'lon': 151.20732}}], 'centralContacts': [{'name': 'David A Baker, MB ChB', 'role': 'CONTACT', 'email': 'db@407.com.au', 'phone': '02 9332 2531'}, {'name': 'Robyn Vale, RN', 'role': 'CONTACT', 'phone': '02 9332 2531'}], 'overallOfficials': [{'name': 'David A Baker, MB ChB', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': '407 Doctors'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': '407 Doctors', 'class': 'OTHER'}, 'collaborators': [{'name': 'Bristol-Myers Squibb', 'class': 'INDUSTRY'}, {'name': 'Merck Sharp & Dohme LLC', 'class': 'INDUSTRY'}]}}}
