Prevention of Chemotherapy Induced Ovarian Failure With Goserelin in BC Patients (ZORO)

Phase 2

Completed

• Conditions: Breast Cancer

• Registration Number: NCT00196846
• Lead Sponsor: German Breast Group

Brief Summary

Study done in young breast cancer patients to prevent chemotherapy induced ovarian failure

Detailed Description

Study Design:

Prospective, randomized, open phase II trial

Schedule:

All patients will receive an anthracycline-containing polychemotherapy.

Patients randomized to Goserelin will receive their first injection of 3.6 mg at least 2 weeks before start of chemotherapy. Goserelin will be given as a subcutaneous injection in the abdominal wall every 4 weeks (28 ± 3 days) until the end of the last chemotherapy cycle.

Primary objective:

•To increase the percentage of patients with normal ovarian function at 6 months after application of (neo)adjuvant, anthracycline-containing polychemotherapy in parallel with Goserelin compared to chemotherapy alone.

Secondary objectives:

To compare the two treatment groups regarding

* Compliance to treatment

* Toxicity

* Quality of life

* Menopausal Symptoms Score

* Ovarian function at 6, 12, 18 and 24 months

* Duration until recovery of regular menstrual period

* Pregnancy rate
