Protection of Ovarian Function With Goserelin Acetate in Premenopausal Early Breast Cancer Patients With Chemotherapy (PROOF)

This study has been withdrawn prior to enrollment.
Information provided by:
AstraZeneca Identifier:
First received: April 23, 2009
Last updated: December 9, 2010
Last verified: December 2010

Primary objective of this study is to determine the effectiveness of goserelin acetate (Zoladex) in preserving ovarian function in premenopausal women undergoing adjuvant chemotherapy for primary invasive breast cancer by documenting persistence or resumption of regular menses via menstrual history, serum FSH and E2 measurements.

The secondary objectives of this study are as follows: To investigate the impact of treatment with chemotherapy with or without goserelin acetate (i.e. impact of the expectation of ovarian function preservation) on participants' quality of life (QOL) by FACT-ES scale, and to compare safety and tolerability of study drugs in two treatment groups by evaluation of adverse events.

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • The ovarian function will be considered as regained, if E2 measurements return to premenopausal levels (equal to or above 20 pg/ml), FSH measurements return to premenopausal levels (less than or equal to 40 IU/L) [ Time Frame: Each 3 months ]
  • The ovarian function will be considered as regained, if menstrual bleeding is observed in two consecutive menstrual cycles [ Time Frame: Each 3 months ]

Secondary Outcome Measures:
  • Quality of life (QOL) through-out the study measured by FACT-ES scale. [ Time Frame: Each 3 months ]

Estimated Enrollment: 102
