Filter by: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.
RATIONALE: Combinations of biological substances in denileukin diftitox may be able to carry cancer-killing substances directly to the cancer cells. Vaccines made from a gene-modified virus and a person's white blood cells may help the body build an effective immune response to kill cancer cells. Giving denileukin diftitox together with vaccine therapy may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects of giving denileukin diftitox together with vaccine therapy in treating patients with metastatic cancer that expresses carcinoembryonic antigen.
This is a multicenter, randomized, prospective, Phase III study in which patients with advanced breast carcinoma previously treated with anthracyclines and taxanes will be randomly assigned to receive one of two treatment options: vinorelbine (Arm A) or gemcitabine plus vinorelbine (Arm B).
The study objective is to evaluate the differences, in terms of first occurrence of a skeletal event, in patients with breast cancer and symptomatic bone metastases, when pamidronate is administered during 2 years, or when it is administered during 6 months, followed by a six month rest period, and again a 6 month treatment period.
This single arm study stratified patients into two treatment cohorts based on HER2-neu overexpression/amplification. Each cohort will be independently powered for the primary endpoint. The study will evaluate the efficacy, safety and impact on quality of life of treatment with oral Xeloda plus intravenous (iv) Taxotere (docetaxel). Patients with HER2-neu negative breast cancer will receive chemotherapy alone with oral Xeloda plus intravenous (iv) Taxotere (docetaxel). Patients with HER2-neu positive breast cancer, will receive the same chemotherapy in combination with intravenous (iv) Herceptin (trastuzumab). Patients will receive 3-weekly cycles of treatment with Xeloda (825mg/m2 oral administration [po] twice daily (bid) on days 1-14) + Taxotere (75mg/m2 iv on day 1). HER2-neu positive patients will also receive Herceptin (loading dose of 4mg/kg iv followed by 2mg/kg iv weekly). The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
