About this study

Official title: A Randomised Phase III Study for Evaluating the Role of the Addition of Ovarian Function Suppression to Tamoxifen in Young Women With Hormone-Sensitive Breast Cancer Who Remain in Premenopause or Regain Menstruation After Chemotherapy

The purpose of this study is to compare 5-year disease free survival rate (DFS rate) between the hormone receptor positive breast cancer patients who were added Goserelin to Tamoxifen for ovarian function suppression after neo-/adjuvant cytotoxic chemotherapy and the hormone receptor positive breast cancer patients who were treated with Tamoxifen.

Read the detailed description
  • To compare overall Survival(OS) between the patients added Goserelin(ZOLADEXTM) to Tamoxifen and the patients treated with Tamoxifen alone in premenopausal status
  • To compare 5-year disease free survival rate (DFS rate) between the patients who took tamoxifen only in postmenopause and the patients added Goserelin(ZOLADEXTM) to Tamoxifen for inducing ovarian function suppression in premenopause
  • To determine the tolerability and safety of Tamoxifen with or without concomitant Zoladex

Study groups in NCT00912548
Study groupRoleWhat they receive
TAM+OFS(E) groupExperimentalPatients should be premenopausal women ,prior to the start of chemotherapy, less than or equal to 45 years of age with oestrogen receptor positive ± progesterone receptor positive who have undergone a primary mass excision, received an neo-/adjuvant chemotherapy ± radiotherapy for their stage I, II or III breast cancer. This arm is ovarian suppression group which have a various starting time of ovarian function suppression after neo-/adjuvant chemotherapy. Ovarian function suppression will be done by administration of LHRH agonist (ZOLADEXTM) for 2 years. After that, the patients will complete taking tamoxifen 20mg/day for 5 years.
Receives: Drug: goserelin; Drug: tamoxifen
TAM(D) groupActive comparatorPatients, less than or equal to 45 years of age with hormone receptor positive breast cancer will be enrolled. Included All the patients have already treated by surgery, neo- or adjuvant chemotherapy ±and/or radiotherapy before enrolment. At 0, 6, 12, 18 and 24 months since the baseline asTsessment(0), the ovarian function status will be evaluated by menstruation status or serum FSH level. If the patients are regarded as the premenopausal women, they will be randomized into the additional ovarian function suppression group or tamoxifen only group. The latter will complete taking tamoxifen 20mg/day for 5 years.
Receives: Drug: tamoxifen
Permanent postmenopausal(A) groupNo interventionPatients, less than or equal to 45 years of age with hormone receptor positive breast cancer will be enrolled. Included All the patients have already treated by surgery, neo- or adjuvant chemotherapy ±and/or radiotherapy before enrolment. Eligible patients except for premenopausal status at the baseline will be followed up until 2 years after the baseline assessment for evaluating the menopausal status. This group still remains to postmenopausal status and will taking tamoxifen 20mg/day for 5 years if they remain in the study.
TAM(B)Active comparatorPatients, less than or equal to 45 years of age with hormone receptor positive breast cancer will be enrolled. Included All the patients have already treated by surgery, neo- or adjuvant chemotherapy ±and/or radiotherapy before enrolment. At 6, 12, 18 and 24 months since the baseline assessment (0), the ovarian function status will be evaluated by menstruation status or serum FSH level. If the patients are regarded as the premenopausal women, they will be randomized into the additional ovarian function suppression group or tamoxifen only group. This group, patients are premenopausal women, they will be randomized into tamoxifen only group, complete taking tamoxifen 20mg/day for 5 years.
Receives: Drug: tamoxifen
TAM+OFS (C)ExperimentalPatients, less than or equal to 45 years of age with hormone receptor positive breast cancer will be enrolled. Included All the patients have already treated by surgery, neo- or adjuvant chemotherapy ±and/or radiotherapy before enrolment. At 6, 12, 18 and 24 months since the baseline assessment (0), the ovarian function status will be evaluated by menstruation status or serum FSH level. If the patients are regarded as the premenopausal women, they will be randomized. This group, patients are premenopausal women, they will be randomized into the additional ovarian function suppression group. Ovarian function suppression will be done by administration of LHRH agonist (ZOLADEXTM) for 2 years. Then, Patients will complete taking tamoxifen 20mg/day for 5 years.
Receives: Drug: goserelin; Drug: tamoxifen

Where is the study taking place?

The record lists 1 site in South Korea. 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?

Results are not available in the source record.

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?

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00912548, which also lists 3 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.
