| Date ISRCTN assigned | 01/07/2001 |
| Local reference number(s) | N/A |

| Scientific title | |
| Acronym | TEAM - Tamoxifen and Exemestane Adjuvant Multicentre trial |
| Disease/condition/study domain | Breast cancer |
| Study hypothesis | To compare the efficacy and tolerability of exemestane versus tamoxifen followed by exemestane given in the adjuvant setting in postmenopausal women with Estrogen Receptor (ER) and/or Progesterone Receptor (PgR)-positive early breast cancer. |
| Design/methodology | Randomised controlled trial |
| Research ethics review | Not provided at time of registration |
| Countries of trial | United Kingdom, Republic of Ireland |
| Participants - inclusion criteria | 1. Women with histologically/cytologically confirmed early adenocarcinoma of the breast, completely excised by surgery with curative intent (Ro) including: a. Any node-positive cancer b. Any cancer greater than or equal to 3 cm c. Node negative cancer, grade II or III and 1 cm or greater 2. ER and/or PgR status positive 3. Postmenopausal 4. Patients on Hormone Replacement Therapy (HRT) which was discontinued at least four weeks prior to randomisation 5. Adequate haematological, renal and hepatic function 6. Accessible for follow-up for the duration of the trial 7. Eastern Cooperative Oncology Group (ECOG) performance status zero, one or two 8. Written informed consent (according to International Conference on Harmonisation [ICH]/Good Clinical Practice [GCP] and local Institutional Review Board [IRB] guidelines) 9. Randomisation within ten weeks of completing surgery +/- adjuvant chemotherapy |
| Participants - exclusion criteria | 1. Positive supraclavicular nodes 2. Evidence of distant metastases (M1) 3. Patients whose chemotherapy was started more than ten weeks after completion of primary surgery 4. Patients who have received previous hormonal treatment as adjuvant treatment for breast cancer 5. Patients who have received neoadjuvant chemotherapy 6. Neoadjuvant hormone therapy more than four weeks duration prior to surgery 7. Severe osteoporosis (bisphosphonates for therapeutic use is not an exclusion criterion) 8.
