About this study
Official title: A Phase III Trial Evaluating The Role Of Exemestane Plus GnRH Analogue As Adjuvant Therapy For Premenopausal Women With Endocrine Responsive Breast Cancer
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using triptorelin, exemestane, and tamoxifen may fight breast cancer by blocking the use of estrogen. It is not yet known whether giving triptorelin together with exemestane is more effective than triptorelin and tamoxifen in treating hormone-responsive breast cancer.
PURPOSE: This randomized phase III trial is studying triptorelin and exemestane to see how well they work compared to triptorelin and tamoxifen in treating premenopausal women with hormone-responsive breast cancer.
Read the detailed description
OBJECTIVES:
- Compare the disease-free survival, breast cancer-free interval, distant recurrence-free interval and overall survival of premenopausal women with endocrine-responsive breast cancer when treated with triptorelin and exemestane vs triptorelin and tamoxifen.
- Compare the quality of life, including late side effects of early menopause, of patients treated with these regimens.
OUTLINE: This is a randomized, international, multicenter study. Patients are stratified according to planned use of concurrent adjuvant chemotherapy (yes vs no), and number of positive lymph nodes (0 vs 1 or more). Treatment duration is 5 years. Patients are followed every 3 months for 1 year, every 6 months for 5 years, and then annually thereafter. Quality of life is assessed at baseline, every 6 months for 2 years, and annually for 3 years.
- Conditions
- Breast Cancer
- Being tested

- Keywords
- stage II breast cancer, stage IIIA breast cancer, estrogen receptor-positive breast cancer, progesterone receptor-positive breast cancer, stage IA breast cancer, stage IB breast cancer

exemestaneDrug
Also called Aromasin

Also called Nolvadex
triptorelinDrug
Also called GnRH analogue, Trelstar Depot, Decapeptyl Depot
| Study group | Role | What they receive |
|---|---|---|
| T+OFS | Active comparator | Ovarian function suppression (OFS) by triptorelin (GnRH analogue) 3.75mg by im injection q28 days for 5 years plus tamoxifen 20mg orally daily for 5 years. Tamoxifen (T) begins after the completion of adjuvant chemotherapy if given, or approximately 6-8 weeks after the initiation of triptorelin. Bilateral oophorectomy or ovarian irradiation was allowed after at least 6 months of triptorelin. Receives: Drug: tamoxifen; Drug: triptorelin |
| E+OFS | Experimental | Ovarian function suppression (OFS) by triptorelin (GnRH analogue) 3.75mg by im injection q28 days for 5 years plus exemestane 25mg orally daily for 5 years. Exemestane (E) begins after the completion of adjuvant chemotherapy if given, or approximately 6-8 weeks after the initiation of triptorelin. Bilateral oophorectomy or ovarian irradiation was allowed after at least 6 months of triptorelin. Receives: Drug: exemestane; Drug: triptorelin |
What is being measured
The primary outcome is the main question the study is designed to answer.
Disease-free Survival
Estimated percentage of patients alive and disease-free at 5 years from randomization, where disease-free survival is defined as the time from randomization to the first appearance of one of the following: invasive breast cancer recurrence at local, regional, or distant site, invasive contralateral breast cancer, second (non-breast) invasive cancer, or death without cancer event; or censored at date of last follow up.
Measured: 5-year estimate reported at a median follow-up of 72 months
Secondary outcomes (3)
Breast Cancer-free Interval
Estimated percentage of patients alive and disease-free at 5 years from randomization, where breast cancer-free interval is defined as the time from randomization to the invasive breast cancer recurrence at local, regional, or distant site, or invasive contralateral breast cancer; or censored at date of last follow up.
Measured: 5-year estimate reported at a median follow-up of 72 months
Distant Recurrence-free Interval
Estimated percentage of patients alive and disease-free at 5 years from randomization, where distant recurrence-free interval is defined as the time from randomization to breast cancer recurrence at a distant site; or censored at date of last follow-up
Measured: 5-year estimates reported at a median follow-up of 72 months
Overall Survival
Estimated percentage of patients alive at 8 years from randomization, where overall survival is defined as the time from randomization to death from any cause; or censored at date last known alive.
Measured: 8-year estimates, reported at a median follow-up of 9 years

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using triptorelin, exemestane, and tamoxifen may fight breast cancer by blocking the use of estrogen. It is not yet known whether giving triptorelin together with exemestane is more effective than triptorelin and tamoxifen in treating hormone-responsive breast cancer.
PURPOSE: This randomized phase III trial is studying triptorelin and exemestane to see how well they work compared to triptorelin and tamoxifen in treating premenopausal women with hormone-responsive breast cancer.
Detailed description
OBJECTIVES:
- Compare the disease-free survival, breast cancer-free interval, distant recurrence-free interval and overall survival of premenopausal women with endocrine-responsive breast cancer when treated with triptorelin and exemestane vs triptorelin and tamoxifen.
- Compare the quality of life, including late side effects of early menopause, of patients treated with these regimens.
OUTLINE: This is a randomized, international, multicenter study. Patients are stratified according to planned use of concurrent adjuvant chemotherapy (yes vs no), and number of positive lymph nodes (0 vs 1 or more). Treatment duration is 5 years. Patients are followed every 3 months for 1 year, every 6 months for 5 years, and then annually thereafter. Quality of life is assessed at baseline, every 6 months for 2 years, and annually for 3 years.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing exemestane, tamoxifen and triptorelin in people with Breast Cancer, run by ETOP IBCSG Partners Foundation at 228 sites in 17 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 228 sites in United States, Australia, Germany, Switzerland, Italy and 12 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Apr 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease-free Survival (time frame: 5-year estimate reported at a median follow-up of 72 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00066703, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2026.
