Clinical activity will be measured by objective tumor response rates observed after treatment with XR9576 in combination with taxane or anthracycline containing chemotherapy in patients previously resistant to the same agent(s).\n\nThe secondary objectives of the study are to assess the biological activity of XR9576 and evaluate MDR-1 expression in these tumors. The MDR-1 inhibitory activity of XR9576 will be evaluated by serial sestamibi scans of the tumor. MDR-1 expression will be detected by immunohistochemistry.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion criteria:\n\n* Histologically proven breast cancer with primary resistance to anthracyclines (doxorubicin, epirubicin) or taxane (paclitaxel, docetaxel) or both. Primary chemotherapy resistance is defined for the purpose of this protocol as any of the following:\n\n 1. Progression after a minimum of 1 cycles of therapy, or\n 2. Stable disease after a minimum of 2 cycles of therapy or,\n 3. Relapse within 6 months after completion of an anthracycline or/and taxane containing chemotherapy regimen.\n* Patients with anthracycline/taxane resistance INOPERABLE, locally advanced breast cancer are eligible.\n* Patients must have measurable disease as defined by the RECIST criteria in their breast/nodal regions or at a distant organ site(s).\n* There is no limit on prior hormonal therapies but only one prior chemotherapy for metastatic breast cancer is allowed.\n* Patients may receive concomitant bisphosphonate therapy for bone metastasis.\n* Patients may continue Herceptin if it has previously been started. Herceptin cannot be added to the chemotherapy regimen as a new agent at the same time when XR9576 is initiated.\n* Patients much have recovered from acute toxic effects of any prior therapy.\n* Zubrod performance status less than or equal to 2.\n* Adequate bone marrow function: platelets greater than or equal to 100,000/mm3, ANC greater than or equal to 1500 cells/mm3, hemoglobin greater than or equal to 8g/dl.\n* Normal renal function: creatinine less than or equal to 2.0 mg/dl. Adequate liver function: bilirubin less than or equal to 1.5 mg/dl. Transaminase (SGOT) and alkaline phosphatase must be less than or equal to 1.5 x of the upper limit of normal in the absence of bone or liver metastasis, or less than or equal to 2.5 x of the upper limit of normal in the presence of radiologically apparent liver metastasis or bone metastasis, respectively.\n* Female patients must be of non-lactating and using adequate contraception if premenopausal. Beta-HCG will be checked in premenopausal patients if clinically indicated.\n* Patients with brain metastases whose disease remained stable for more than 3 months after completing therapy to the brain are eligible.\n* Written informed consent.\n\nExclusion criteria:\n\n* More than 1 chemotherapy regimen for metastatic breast cancer.\n* Patients who relapsed more than 6 months after completion of anthracycline or taxane therapy.\n* Current treatment with a non-taxane, non-anthracycline based chemotherapy.\n* Uncontrolled psychiatric, or social (addictive) disorders that would preclude obtaining informed consent or patient participation in the study.\n* Clinical contraindication of continued anthracycline or taxane therapy. For patients who show primary resistance to anthracyclines this includes greater than 300 mg/m2 maximum life-time cumulative dose of doxorubicin, symptomatic heart failure, history of heart failure, recent myocardial infarction (less than 6 months) or left ventricular ejection fraction below normal range. For patients with primary resistance to taxanes, persistent grade 2 or greater neuropathy (neuropathy that interferes with function).\n* Patients with operable primary breast cancer are not eligible.\n* Patients who have developed primary resistance to the chemotherapy combination of doxorubicin/docetaxel.'}, 'identificationModule': {'nctId': 'NCT00048633', 'briefTitle': 'Phase II Study to Evaluate Tariquidar (XR9576), a Selective MDR-1 Inhibitor, in Chemotherapy Resistant Advanced Breast Cancer', 'organization': {'class': 'INDUSTRY', 'fullName': 'QLT Inc.'}, 'orgStudyIdInfo': {'id': 'TQD BRST 001'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Tariquidar', 'interventionNames': ['Drug: Chemotherapy']}], 'interventions': [{'name': 'Chemotherapy', 'type': 'DRUG', 'armGroupLabels': ['Tariquidar']}]}, 'contactsLocationsModule': {'locations': [{'zip': '32207-5905', 'city': 'Jacksonville', 'state': 'Florida', 'country': 'United States', 'facility': 'Florida Oncology Associates', 'geoPoint': {'lat': 30.33218, 'lon': -81.65565}}, {'zip': '47591', 'city': 'Vincennes', 'state': 'Indiana', 'country': 'United States', 'facility': 'Medical Center of Vincennes', 'geoPoint': {'lat': 38.67727, 'lon': -87.52863}}, {'zip': '76012', 'city': 'Arlington', 'state': 'Texas', 'country': 'United States', 'facility': 'Arlington Cancer Center', 'geoPoint': {'lat': 32.73569, 'lon': -97.10807}}, {'zip': '77030-4009', 'city': 'Houston', 'state': 'Texas', 'country': 'United States', 'facility': 'MD Anderson Cancer Center', 'geoPoint': {'lat': 29.76328, 'lon': -95.36327}}], 'overallOfficials': [{'name': 'Graeme R Boniface', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Sponsor GmbH'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'QLT Inc.', 'class': 'INDUSTRY'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
