As a consequence, enfuvirtide resistant virus can emerge. It is not yet known if enfuvirtide has continued virologic or immunologic benefit after the drug-resistant variant emerges. Interrupting enfuvirtide may reduce the accumulation of enfuvirtide mutations and may allow for a potent response of enfuvirtide with future regimens.\n\nSubjects must have evidence of viral replication (HIV RNA \\> 1,000 copies/ml on two consecutive measurements) while on a stable antiretroviral regimen containing enfuvirtide. Patients will then interrupt enfuvirtide while continuing all other antiretroviral agents. Subjects will be seen weekly for four weeks, every two weeks for an additional 8 weeks, and then every four weeks through week 48.\n\nPlasma HIV RNA levels and CD4+/CD8+ T cell counts will be measured in real time at each visit, and provided to the referring primary care physician. Subjects will be allowed to resume enfuvirtide at any time during the course of this study. Subjects will be encouraged to resume enfuvirtide (with or without modifying the background regimen) if plasma HIV RNA levels increase by \\> 0.5 log on two consecutive occasions. Subjects are seen every four weeks for 24 weeks after enfuvirtide is resumed.\n\nPlasma will be collected at those visits for HIV RNA and stored for retrospective genotype/phenotype evaluation.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Currently receiving continuous enfuvirtide-based antiretroviral therapy.\n* Documentation of recent plasma HIV RNA level greater than the lower limit of detection (measured within the preceding 4 weeks)\n* Screening plasma HIV-1 RNA level \\> 1000 copies/mL.\n* Negative serum pregnancy test (for women of childbearing potential) documented within the 14-day period prior to study entry.\n* Subjects must be able to give written informed consent and agree to abide by the requirements of the study.\n\nExclusion Criteria:\n\n* Unstable HIV disease status such that interrupting any antiretroviral therapy poses significant short-term risk for disease progression (as determined by study investigators and referring primary care provider).\n* Female subjects who are pregnant, breastfeeding, or who plan to become pregnant during the study.\n* Active hepatitis C infection requiring treatment with an interferon-based regimen.\n* Evidence of active, untreated opportunistic infections or unexplained temperature which is \\> 38.5°C for seven consecutive days, within 30 days prior to the first screening visit.'}, 'identificationModule': {'nctId': 'NCT00187551', 'briefTitle': 'Pilot Study Evaluating Interruption of Enfuvirtide (Fuzeon, T20) in Patients With Enfuvirtide Resistance', 'organization': {'class': 'OTHER', 'fullName': 'University of California, San Francisco'}, 'officialTitle': 'Partial Treatment Interruptions in HIV-1 Patients With Multi-Drug Resistant Virus', 'orgStudyIdInfo': {'id': 'H8211-18804-05'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'interruption of enfuvirtide', 'description': 'enfuvirtide interruption', 'interventionNames': ['Other: Interruption of enfuvirtide', 'Other: enfuvirtide interrupton']}], 'interventions': [{'name': 'Interruption of enfuvirtide', 'type': 'OTHER', 'description': 'treatment interruption', 'armGroupLabels': ['interruption of enfuvirtide']}, {'name': 'enfuvirtide interrupton', 'type': 'OTHER', 'description': 'enfuvitide will be interrupted in patients harboring resistant virus', 'armGroupLabels': ['interruption of enfuvirtide']}]}, 'contactsLocationsModule': {'locations': [{'zip': '94110', 'city': 'San Francisco', 'state': 'California', 'country': 'United States', 'facility': 'San Francisco General Hospital', 'geoPoint': {'lat': 37.77493, 'lon': -122.41942}}], 'overallOfficials': [{'name': 'Steven G Deeks, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of California, San Francisco'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of California, San Francisco', 'class': 'OTHER'}, 'collaborators': [{'name': 'Universitywide AIDS Research Program', 'class': 'OTHER'}], 'responsibleParty': {'oldNameTitle': 'Steven Deeks', 'oldOrganization': 'UCSF'}}}}
