German Preoperative Adriamycin Docetaxel Study

Status Completed

Clinical Trial Summary

The primary objective of this trial is to determine the rate of pathologically complete remissions following a preoperative dose-intensified therapy with doxorubicin and docetaxel with or without tamoxifen in patients with operable carcinoma of the breast. Secondary aims are to assess the rate of clinical complete and partial responses, of breast-conserving operations, and the toxicity of chemotherapy with and without tamoxifen.

Women meeting the following criteria will be eligible for the study: operable breast cancer (T³3cm N0-2 M0), histologically confirmed diagnosis by core-cut needle or incisional biopsy, and measurable disease by mammography or sonography or breast MRI (best appropriate method has to chosen by investigator). After the patients have given written informed consent, they will be randomised to the study treatments. All patients are scheduled to receive 4 cycles of combination chemotherapy consisting of doxorubicin 50 mg/m² (15-min i.v. infusion) and docetaxel 75 mg/m² (1-h i.v. infusion). The patients allocated to group I additionally receive oral doses of tamoxifen 30 mg once daily, starting on the first day of chemotherapy, while chemotherapy alone is administered to patients of group II. Cycles should be repeated every 14 days, followed by surgery 8 weeks after initiation of the trial. Surgery consists of removal of the remaining tumour (breastconserving resection or mastectomy) and axillary dissection. Patients with no response or even progression of the primary tumour can be treated to the discretion of the investigator but should be followed up according to protocol. If a partial or complete tumour response has been achieved, radiotherapy is given to the remaining breast in patients undergoing breast conserving therapy, and tamoxifen treatment is continued for a further 5 years.

Response will be assessed between the 4th cycle and surgery, using the best appropriate method. Clinical evaluation should be performed after each cycle. It is planned to recruite 200 patients during a period of 1 year.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
