Triptorelin for Preserving Ovarian Function in Premenopausal Women Receiving Chemotherapy for Early-Stage Breast Cancer

Breast Cancer Clinical Trial

Official title: Preservation of Ovarian Function in Young Women Treated With (Neo) Adjuvant Chemotherapy for Breast Cancer: A Randomized Trial Using the Gonadotropin-releasing Hormone (GnRH) Agonist (Triptorelin) During Chemotherapy

Status Terminated

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Chemoprotective drugs, such as triptorelin, may protect normal ovarian cells from the side effects of chemotherapy.

PURPOSE: This randomized phase II trial is studying how well triptorelin works in preserving ovarian function in premenopausal women who are receiving chemotherapy for early-stage breast cancer.

Clinical Trial Description

OBJECTIVES:

Primary

• Determine the protective effect of chemical ovarian suppression using triptorelin on the preservation of ovarian function in premenopausal women with early-stage operable breast cancer undergoing adjuvant or neoadjuvant systemic chemotherapy.

Secondary

• Determine the rate of chemotherapy-related amenorrhea in patients treated with this drug.

• Determine the value of inhibin A and B as alternative markers of premature ovarian failure in patients treated with this drug.

• Determine quality of life of patients treated with this drug.

• Determine disease-free and overall survival of patients treated with this drug.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to age (< 35 years vs 35 to 39 years vs > 39 years); concurrent neoadjuvant or adjuvant systemic chemotherapy (fluorouracil, epirubicin, and cyclophosphamide [6 courses] OR fluorouracil, doxorubicin, and cyclophosphamide [6 courses] vs doxorubicin and cyclophosphamide [AC] [4 courses] vs doxorubicin and cyclophosphamide [AC] [4 courses] followed by a taxane [4 courses]); and hormone receptor status (estrogen receptor [ER]- AND progesterone receptor [PR]-negative vs ER- OR PR-positive).

• Arm I: Beginning within 1-4 weeks before the start of chemotherapy, patients receive triptorelin intramuscularly once monthly for 4-6 months during neoadjuvant or adjuvant systemic chemotherapy.

• Arm II: Patients receive neoadjuvant or adjuvant systemic chemotherapy only. Quality of life is assessed at baseline, monthly during treatment, every 6 months for 2 years, and then annually for 3 years.

Patients are followed every 6 months for 2 years and then annually for 3 years.

PROJECTED ACCRUAL: A total of 138 patients (69 per treatment arm) will be accrued for this study within 35 months. ;
