About this study

Official title: Multicenter Prospective, Parallel-controlled Phase III Clinical Study on Comparing Efficacy of Tamoxifen Versus Toremifene in CYP2D6 Intermediate/Poor Metabolizers of Premenopausal Patients With ER-positive Early Breast Cancer

This clinical trial is designed to be a multi-center prospective, parallel-controlled Phase III clinical study. In this study, the efficacy of tamoxifen versus toremifene shall be compared in CYP2D6 intermediate/poor metabolizers of premenopausal patients with estrogen receptor-positive early breast cancer.

Read the detailed description

STUDY BACKGROUND Breast cancer is a serious disease that threatens human health and life. Especially in China, the incidence rate is increasing year by year. According to WHO data, the incidence of breast cancer in China in 2020 will reach 214,000. Selective estrogen receptor modulators (SERMs) are a classic form of endocrine therapy for early breast cancers, but not all hormone receptor positive breast cancers benefit from specific SERMs. Numerous studies have shown that CYP2D6 variant carriers (around 50% CYP2D6 variant carriers in Chinese population) will not benefit a lot from tamoxifen, and combined use of CYP2D6 inhibitors will further affect the efficacy of tamoxifen. However, studies on another SERM drug - toremifene have shown that its metabolism and pharmacological effects are not influenced by CYP2D6 genotype or enzyme activity. Therefore, in the principle of individualized medicine, it is necessary to compare the efficacy of using tamoxifen and toremifene in CYP2D6 variant carriers in China so as to provide more guidance for clinical use.

OBJECTIVES:

  1. The main purpose of this study is to compare 5-year disease-free survival rate of adjuvant endocrine therapy with tamoxifen and toremifene in premenopausal women with estrogen receptor-positive early breast cancer who are CYP2D6 intermediate/poor metabolizers.
  2. The secondary purpose of this study includes:
  3. To compare 5-year overall survival (OS) and safety of adjuvant endocrine therapy with tamoxifen and toremifene in premenopausal patients with estrogen receptor-positive early breast cancer who are CYP2D6 intermediate/poor metabolizers.
  4. To compare the changes of plasma concentration of the parent drugs and metabolites of tamoxifen and toremifene in premenopausal patients with estrogen receptor-positive early breast cancer who are CYP2D6 intermediate/poor metabolizers.
  5. To assess the pharmacokinetics of tamoxifen and toremifene in premenopausal patients with estrogen receptor-positive early breast cancer who are CYP2D6 intermediate/poor metabolizers.

OUTLINE:

First, CYP2D6 genotype screening shall be conducted in premenopausal patients with estrogen receptor-positive early breast cancer in order to determine the frequency of different alleles. Then, patients who are CYP2D6 intermediate/poor metabolizers (with *4, *5, *10, *14, *17, *41 alleles) shall be stratified and randomized at the ratio of 1:1 ratio: allele status of CYP2D6 CYP2D6 intermediate/poor metabolizer (Heterozygous or homozygous), lymph node metastasis (with vs. without), prior chemotherapy (with vs. without), and HER2 status (positive vs. negative). Included patients shall be divided into two groups. One group will be given Tamoxifen (10mg Bid) for 5 years and the other group will be given toremifene (60mg qd) for 5 years. Then 5-year disease-free rate and overall survival and safety will be compared between these two groups. At Month 6, pharmacokinetic study on tamoxifen, toremifene and their metabolites will be conducted on patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Disease-Free Survival

    The time period from randomization to local or distant invasive cancer recurrence, contralateral invasive breast cancer, second (non-breast) primary invasive cancer and all-cause death

    Measured: Within 5 years after randomization

Secondary outcomes (3)
  1. Overall Survival

    The time period from randomization to all-cause death

    Measured: Within 5 years after randomization

  2. Adverse drug reaction

    The time period from administration to adverse events (dyslipidemia, endometrial hyperplasia) with confirmed, probably and possibly relevant relationship to trial medicine.

    Measured: Within 5 years after administration

  3. Serum drug concentration

    Blood level of trial medicines and their metabolites

    Measured: Within 6 months after administration

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tamoxifen and Toremifene in people with Breast Cancer Female, run by Chinese Anti-Cancer Association at 21 sites 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 7 inclusion and 17 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 22 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites 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.

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?

Contact Zhimin Shao, M. D. (13611709888, zhimingshao@yahoo.com), 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: Within 5 years after randomization). 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 22 Nov 2017.
