Scientific titleTrial of accelerated adjuvant chemotherapy with capecitabine in early breast cancer
Study acronymTACT2
Study objectivesA randomised, phase III clinical trial with a 2 x 2 factorial design addressing two hypotheses:
1. That accelerating Epirubicin will improve the efficacy of the sequential schedules (based originally on the NEAT epirubicin/CMF schedule).
2. That the substitution of CMF by Capecitabine will not be detrimental to patient outcome but will offer advantages in Quality of Life and/or toxicity.
Ethics approval(s)Protocol TACT2: Version 1d approved on the 23/09/2005, UK Ethics Committee MREC ref: 04/MRE00/88
Version 3 approved on the 13/05/2008. Current protocol, version 5 approved July 2009
Health condition(s) or problem(s) studiedEarly breast cancer
InterventionEpirubicin followed by cyclophosphamide, methotrexate and 5-fluorouracil (5-FU) (E-CMF)
Accelerated E-CMF
Epi-capecitabine
Accelerated epi-capecitabine
Intervention typeDrug
PhasePhase III
Drug / device / biological / vaccine name(s)Capecitabine, cyclophosphamide, epirubicin hydrochloride, fluorouracil, methotrexate, pegfilgrastim
Primary outcome measure(s)

Target sample size at registration4400
Total final enrolment4391
Key inclusion criteriaPatients with early breast cancer for whom treatment with anthracycline chemotherapy is indicated.

1. Histological diagnosis of invasive breast carcinoma
2. Completely resected disease with negative surgical margins (apart from deep margin if full thickness resection).
3. Early stage disease (T0-3 N0-2 M0) with no evidence of distant metastases on routine staging
4. Definite indication for adjuvant chemotherapy
5. ECOG status 0 or 1
6. Aged over 18 years (no upper age limit)
7. Fit to receive any of the trial chemotherapy regimens, with adequate bone marrow, hepatic, and renal function ie:
7.1 Hb > 9g/dL; WBC > 3 ´ 109/L; platelets > 100 x 109/L
7.2 Bilirubin within normal range (unless known Gilbert’s disease)
7.3 AST/ALT = 1.5 x Upper limit of normal (ULN)
7.4 Albumen within normal range
7.5 Creatinine = 1.5 x ULN and calculated creatinine clearance using Cockroft-Gault formula > 50 ml/min
7.6 No active, uncontrolled infection
8. Signed TACT2 trial consent form
9. Randomisation within 8 weeks of surgery, but ideally within 1 month
10. No previous chemotherapy, hormonal therapy or radiotherapy for the treatment of pre-invasive or invasive cancer except:
10.1 Previous radiotherapy for basal cell carcinoma
10.2 Previous pre-operative endocrine therapy provided that there was no evidence of progression during this therapy, that it was for less than 6 weeks in duration, and was stopped at least one month prior to trial entry
11. No previous malignancy except in the case of DCIS, or basal cell carcinoma or cervical carcinoma in situ, or where the patient has been disease-free for 10 years, and where treatment consisted solely of resection.
12. Non-pregnant and non-lactating, with no intention of pregnancy during chemotherapy, and prepared to adopt adequate contraceptive measures if pre-menopausal and sexually active
13. No concomitant medical, psychiatric or geographic problems that might prevent completion of treatment or follow-up
Key exclusion criteria1. Only cytological proof of malignancy
2. No evidence of invasive breast cancer
3. Previous invasive breast cancer or bilateral breast cancer (surgically treated DCIS or LCIS is allowed)
4. Locally advanced breast cancer (T4 and/or N3 disease)
5. Patients who have had breast conserving surgery in whom there is a contra-indication for, or refusal of post-operative radiotherapy
6. Patients with positive surgical margins unless either:
6.1 Deep surgical margin involvement following full thickness resection
6.2 Non-invasive cancer at surgical margins and a decision to perform mastectomy on completion of chemotherapy has already been made
7. Patients not able or willing to give informed consent
8. Patients known not to be available for a minimum of 5 years' follow-up
9. Patients with known serious viral infection such as active Hepatitis B, Hepatitis C or HIV
10. Patients with significant cardiac disease, such as impaired left ventricular function or active angina (requiring regular anti-anginal medication and/or resulting in restricted physical activity)
11. Patients with a history of significant renal impairment or disease
12. Simultaneous participation in the active intervention phase of another treatment trial
13. Being approached and recruited into the active intervention phase of another treatment trial two months before or after recruitment into TACT2
