Filter by:This is an open-label, randomized, multicenter phase III trial to assess the efficacy of early administration of zoledronate versus observation in delaying bone-related symptoms in metastatic breast cancer patients.
This is a prospective, randomised phase III trial, to compare the efficacy and safety profiles of two types of adjuvant chemotherapy regimens for human epidermal growth factor receptor 2 (HER2) negative, node positive breast cancer patients. Control Arm: This includes 4 cycles of EC 90/600 mg/m2 day 1 every 3 weeks, followed by 4 cycles of T 100 mg/m2 day 1 every 3 weeks. Experimental Arm: This includes 4 cycles of ET 90/75 mg/m2, day 1 every 3 weeks, followed by 4 cycles of capecitabine 1250 mg/m2, twice a day, via oral intake, for 14 days, and then a one-week rest period. Premenopausal women with hormone receptor positive tumours must receive 5 years of tamoxifen after the end of chemotherapy. Postmenopausal women with hormone receptor positive tumours can receive tamoxifen or aromatase inhibitors (or both) after the end of chemotherapy. Patients may receive radiotherapy when clinically indicated.
The efficacy of adjuvant chemotherapy is limited in patients with a high risk of recurrence. Also, for axillary positive node patients, optimum chemotherapy regimens are still under discussion. Some previous studies suggest that, in the subset of node-positive patients, treatments based on sequential administration of anthracyclines and taxanes are more efficient. Paclitaxel dose-dense (weekly) administration renders an improved therapeutic index (activity/toxicity). The study is designed to compare 6 courses of FEC scheme (600/90/600), a combination of proven efficacy in node positive breast cancer patients, versus 4 FEC courses followed by 8 weekly paclitaxel administrations (100mg/m2). The study hypothesis is that 5-year disease-free survival in the control arm will be 60%. The investigators expect to increase this by 8% with the experimental treatment. With an alpha error of 0.05, 80% power, and a post-randomization estimated drop-out rate of 10%, 1250 patients are needed, 625 per arm.
This is an open-label study to assess the efficacy and tolerability of the combination Myocet®/Taxotere®/Herceptin® as primary treatment for HER2 positive breast cancer patients. HER2 status will be confirmed centrally by fluorescence in situ hybridization (FISH). Phase I: Initial doses will be: Myocet: 50-60 mg/m² day 1 every 3 weeks; Taxotere 60-75 mg/m² day 1 every 3 weeks; and Herceptin (4) 2 mg/kg weekly. Sample size will depend on the number of patients recruited during dose escalation. Three patients must be recruited in each dose level. If one out of three experiences a dose-limiting toxicity (DLT), 3 more patients must be recruited in the same dose level. Considering that there are 4 dose levels to be tested, the estimated number of patients is 9 to 24. Patients receiving the recommended dose (RD) will be incorporated into phase II of the study.
This is a prospective, open-label, randomized, phase III trial. Patients will be stratified after breast surgery, as per investigational site; menopausal status; node negative diagnosis, as per sentinel-node technique versus lymphadenectomy; hormone receptor status (positive versus negative).
Treatment consists of 4 AC cycles followed by 2 weekly docetaxel cycles (12 infusions). The pathological complete response rate obtained in previous studies is around 12%. The expected pathological complete response rate in this study is 25%. With an alpha error of 0.05 and a beta error of 0.2, and following Simon´s 2 phase test, 19 patients are needed initially. With 2 pathological complete responses, patient recruitment will continue until approximately 61 patients are recruited. Twelve pathological complete responses are needed to confirm the study hypothesis.
This is a multicenter, open-label, phase II trial to assess the efficacy of the GAT neoadjuvant regimen in patients with stage III breast cancer.
This is a pivotal phase II, multicenter, open-label trial, designed to compare the efficacy of exemestane versus anastrozole as a first line treatment for advanced breast cancer. One hundred postmenopausal patients, with metastatic, positive hormone receptor breast cancer will be enrolled in this trial.
This is a randomized, prospective and multicenter phase IV clinical trial, which has been designed as a phase III study. One hundred fifty-four women (77 per treatment arm) will be recruited in the study.
The advent of mammography and increased awareness of breast cancer has resulted in detection of smaller tumors, the majority of which would not have had metastasized to the axillary lymph nodes. The sentinel node (SN) is presumably the first echelon node in the axillary basin to become involved with metastatic breast cancer cells. Sentinel node biopsy (SNB) in operable breast cancer has gained popularity since it promises to avoid treatment of the axilla when the nodes are negative for metastasis. Advances in technology (radio-guided SNB) is associated with a risk of false negative SN reporting in 4-12%. The consequence of leaving behind untreated positive non-sentinel nodes in the axilla is a potential risk for axillary recurrence. Axillary sampling is a simple and inexpensive procedure in which level I nodes are removed by a blind dissection. The investigators critically analyzed the efficacy of both the procedures separately in consecutive pilot studies i.e., targeted SNB versus blind axillary sampling. The current study is planned as a prospective comparison study where a patient undergoes both the procedures in the same surgical intervention and thus provides an immediate comparison of the two techniques with respect to their effectiveness.
