About this study

Official title: Comparative Evaluation of Efficacy and Safety of Toremifene, Tamoxifen, and Aromatase Inhibitor Plus Ovarian Suppression in Hormone Receptor-Positive Early Breast Cancer Among Non-Low-Risk Premenopausal Women: A Real-World Study

This study aims to enroll premenopausal patients, with early breast cancer who are non-low-risk and hormone receptor-positive and have undergone prior surgical intervention at the Breast Cancer Center of Sun Yat-sen Memorial Hospital, Sun Yat-sen University. These participants, receiving tamoxifen (TAM), toremifene (TOR), or aromatase inhibitors (AI) as adjuvant endocrine therapy and undergoing ovarian function suppression (OFS) treatment, will be divided into three groups, namely TOR+OFS, TAM+OFS, AI+OFS. The study will compare the efficacy and safety of TOR+OFS to that of TAM+OFS or AI+OFS in premenopausal estrogen receptor-positive breast cancer patients by comparing the 5-year disease-free survival (DFS) and quality of life etc. The objective is to evaluate whether TOR+OFS is non-inferior to TAM+OFS or AI+OFS in this specific patient population.

Read the detailed description

Selective estrogen receptor modulators (SERM), tamoxifen (TAM) and toremifene (TOR), have been proven to be effective in premenopausal estrogen receptor positive breast cancer patients with similar outcomes. In addition, many large-scale long-term follow-up clinical tials, such as ABCSG XII, SOFT, TEXT, ASTRRA, and ZIPP, have confirmed that premenopausal patients with hormone-receptor-positive breast cancer at intermediate to high risk could benefit from ovarian function suppression (OFS) combined with aromatase inhibitor (AI) or TAM. The Asian Breast Cancer Cooperative Group (ABCCG) also recommends OFS+TAM or OFS+AI for the treatment in this specific patient population. Notably, the therapeutic efficacy and safety profile of OFS in conjunction with TOR have yet to be investigated, nor has its comparative effectiveness with OFS plus TAM or OFS plus AI been established.

Questions about this trial

What is this clinical trial studying?

An observational study of Hormone-receptor-positive Breast Cancer and Premenopausal Breast Cancer, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. 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: status not confirmed, as of the sponsor's last update on 18 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Chang Gong, doctor (13925089353, gchang@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

disease free survival (time frame: 5 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 May 2023.
