Summary
Design
Prospective, randomized Phase III trial
Study Population
Patients with HER-2 positive metastatic breast cancer and progression during or after previous chemotherapy and trastuzumab treatment as follows:
- Taxanes + trastuzumab given as adjuvant therapy
- Taxanes + trastuzumab given as first line therapy for palliation
- Trastuzumab given as first line therapy for palliation alone or in combination with chemotherapeutic agents other than capecitabine or taxanes
- Trastuzumab has to be given previously for at least 12 weeks, treatment-free interval of trastuzumab for a maximum of 6 weeks. No more than one chemotherapy for palliation
Aims
The primary aim is to compare the time to disease progression in patients with HER 2 positive metastatic breast cancer and progression after previous treatment with trastuzumab randomized to capecitabine alone or in combination with trastuzumab.
Secondary Aims/Endpoints
- To compare the objective response rate between the two arms.
- To compare the duration of response.
- To compare the clinical benefit defined as CR, PR, or stable disease >24 weeks between the two arms.
- To evaluate the safety of the capecitabine + trastuzumab combination.
- To compare overall survival between the two arms.
Treatment
- Capecitabine 2500 mg/m2 orally day 1–14 q day 22 until progression or unacceptable toxicity, patient’s request or withdrawal from study, and discontinuation of Trastuzumab.
- Capecitabine and Trastuzumab Capecitabine 2500 mg/m2orally day 1–14 q day 22 until progression or unacceptable toxicity, patient’s request or withdrawal from study.
- Trastuzumab 6 mg/kg body weight every 3 weeks intravenous (i.v.) as a 90 minutes infusion until progression or unacceptable toxicity, patient's request or withdrawal from study.

Summary
- A multi-centre, Phase III, placebo controlled randomized trial. Patients are randomized between 2 years celecoxib and placebo in a 2:1 ratio in favour of celecoxib
Chemotherapy
Prior to randomisation, patients may have received chemotherapy (all HR negative patients MUST have received chemotherapy). All patients who have received chemotherapy should have finished their treatment, which will have consisted of at least 4 cycles. The schedule of preference is FEC 3-weekly for 6 courses, however, other dose schedules of FEC or FAC plus combinations that contain EC/AC followed by a taxane, or Epirubicin/Doxorubicin plus a taxane are permitted. CMF may be substituted for patients where Epirubicin is contraindicated.
Aims
The primary aim is to assess the disease-free survival (DFS) benefit of 2 years adjuvant therapy with the COX-2 inhibitor celecoxib compared with placebo in primary breast cancer patients.
Secondary Aims/Endpoints
- To compare overall survival.
- To define the safety of adjuvant therapy with celecoxib in this patient population.
- To compare the incidence of second primary cancers.
- In postmenopausal hormone receptor (HR) positive patients, to assess tolerability of celecoxib with tamoxifen.
- To assess DFS benefit of 2 years adjuvant celecoxib compared with placebo in HR positive (i.e. ER positive and/or PR positive) and in HR negative (i.e. ER negative/PR negative) disease.

Summary
- Breast cancer complicating pregnancy is a rare coexistence. Breast cancer is after the age of 25 the most common malignancy in pregnancy. Little is known about the incidence in Germany and Western Europe. We therefore want to initiate a trial collecting prospectively as much data as possible for the diagnostic, treatment, and maternal and foetal outcome during pregnancy. The primary endpoint is the foetal outcome 4 weeks after delivery. Secondary endpoints will include maternal outcome, pregnancy outcome, diagnostic procedures used and the biology of the tumour. A flow sheet for the treatment is given and the acceptance of these guidelines will be evaluated.
Primary Endpoint
- Foetal outcome 4 weeks after delivery.
Secondary Endpoints
- Maternal outcome of pregnancy.
- Stage of and biological characteristics of breast cancer.
- Breast cancer therapy (treatment, response to chemotherapy, type of surgery).
- Sensitivity and specificity of diagnostic procedures (palpation, US, mammogram).
- Outcome of the newborn after 5 years of therapy.
- Outcome of breast cancer 5 years after diagnosis.
Scheme
Prospective and retrospective registration of patients who have been diagnosed with breast cancer during pregnancy

Summary
Design
Prospective, randomized, open Phase III trial
Study Population
Completely resected unilateral or bilateral primary carcinoma of the breast with histologically detectable tumour residuals (ypT2-4) and or histologically confirmed involvement of axillary nodes (ypN1-3) after prior preoperative chemotherapy for at least 4 cycles, of which at least two must contain a taxane and an anthracycline.
Primary Objective
To determine the event-free survival (EFS) after zoledronic acid for 5 years versus no postoperative treatment in patients with “chemo-insensitive” breast cancer (ypT2-4 and/or ypN1–3) after preoperative anthracycline/taxane-containing chemotherapy.
Treatment
Zoledronic acid 4mg (or adjusted dose based on renal function) will be given i.v.:
- Every 4 weeks for the first 6 doses (year 0–0.5)
- Every 3 months for 8 doses (year 0.5–2.5)
- Every 6 months for 5 doses (year 2.5–5)
Patients with hormone sensitive tumours (ER and/or PgR positive) should receive simultaneous endocrine treatment according to current treatment guidelines. In case an aromatase inhibitor is indicated for postmenopausal patients >50 years, letrozole should be used. Letrozole will be provided free of charge.

All patients will receive 4 cycles of EC:
- Epirubicin 90mg/m2 given simultaneously with
- Cyclophosphamide 600mg/m2, all day 1 q day 21
Thereafter they will be randomized to:
- Arm A: Docetaxel 100mg/m2day 1 q day 21 for 4 cycles (EC-Doc)
- Arm B: Docetaxel 75mg/m2day 1 q day 21 for 4 cycles concomitantly given with Capecitabine 1800mg/m2day 1–14 q day 21 for 4 cycles (EC-DocX)
- Arm C: Docetaxel 75mg/m2day 1 q day 21 for 4 cycles followed by Capecitabine 1800mg/m2day 1–14 q day 21 for 4 cycles (EC-Doc-X)
Patients with HER-2/neu positive tumors will receive trastuzumab 6mg/kg intravenous (i.v.) every 3 weeks concomitantly to cytotoxic treatment, starting with a loading dose of 8mg/kg i.v. on day 1 of the first EC-cycle. A total number of 8 (in the EC-Doc and EC-DocX arm) or 12 (in the EC-Doc-X arm) infusions will be given preoperatively.

Summary
Design
The trial is a prospective, randomized multi-centre open-label Phase III trial that is designed to detect a difference in efficacy between two chemotherapy regimens (FE100C*6 versus FE100C*3 followed by Docetaxel100*3) in high-risk node-negative breast cancer patients. Additionally, risk assessment by the traditional clinico-pathological factors and by tumour-biological factors (aPA/PAI-1) will be compared.
Study Population
Primary breast cancer, tumour size ≥0.5 cm and ≤5cm (pT1b-pT2, pN0, M0), age ≥18 years, ≤70 years
Aims/Endpoints
- Amongst the chemotherapy treated population:
– The primary endpoint of the study is Disease-Free Survival (DFS).
– The secondary endpoints are: Overall Survival (OS) and safety.
- Amongst the entire population of registered patients:
– DFS in each low-risk group (or of each patient group stratified for type of risk selection, respectively).
– The proportion of node-negative breast cancer patients grouped into each low-risk group.
– Side-effects of chemotherapy in each patient group.
Scheme
Update
- 999 patients enrolled as of October 2006.
