E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the ability of Zoreline 3.6 mg SC implant to induce by Visit 7 (Day 29±1 day) of Cycle 1 at the latest and maintain up to Visit 14 (end of treatment; Day 85±2 days) oestradiol plasma suppression (≤30 pg/mL) in women with confirmed endometriosis |
|
E.2.2 | Secondary objectives of the trial |
•To assess general safety and acceptability of the drug and syringe combination in line with standard of care.
•To characterize the goserelin plasma concentration profile (maximum plasma concentration [Cmax], time to reach Cmax [Tmax], minimum plasma concentration [Cmin], area under the plasma concentration-time curve [AUC]) from Visit 2 (Day 1) to Visit 7, from Visit 7 to Visit 12, and from Visit 12 to Visit 14, i.e. during three consecutive treatment cycles, and during follow-up period until Visit 15. The area under the curve will be extrapolated to infinity (AUC0-∞) and terminal (apparent elimination) half-life (t½) will be determined if possible.
•To characterize the (Cmax, AUC) from Visit 2 (Day 1) to Visit 15 including initial flare between Visit 2 (Day 1) and Visit 7, time to achieve menopause level, acute or chronic phenomenon (surge at re-injection between Visit 8 (Day 30) and Visit 9 (Day 32) and potential escape (surge) from Visit 10 (Day 36±1 day) to Visit 14.

4. Use of contraceptive treatments that interfere with oestradiol plasma level 1 week (or 5 half lives; whichever is longest) before IMP administration;
5. Has endometriosis surgery scheduled for between the Screening and Enrolment visit. (Endometriosis surgery allowed following Visit 14 [Day 85±2 days]);
6. Implanted progestin treatment should be released at least 1 month before study enrolment;
7. Has received an investigational drug within the last 28 days before the Screening visit (Visit 1) or longer if considered to possibly influencing the outcome of this study;
8. Has an unstable medical condition or chronic disease such as but not limited to neurological hepatic, renal, cardiovascular, gastrointestinal, pulmonary, or endocrine disease;
9. History or presence of any malignancy other than treated squamous cell/basal cell carcinoma of the skin within the last 5 years;
10. Evidence (including clinically significant abnormal bilirubin and/or albumin values) or history of chronic hepatic disease;
11. Have a repeatable prolongation of the QTc interval at screening (mean QTcB ≥450 ms); or personal or family history of long QT syndrome or significant risk factors of prolonged QT interval arrhythmias. (as determined by the investigator);
12. Patient for which a possible loss in bone mass which in the judgment of the investigator would affect the patient's health;
13. History of severe uncontrolled asthma, anaphylactic reactions, or severe urticarial and/or angioedema, and particularly, history of hypersensitivity towards any components of the IMP;
14. Other abnormal laboratory results which in the judgment of the investigator would affect the patient's health or the outcome of the study;
15. Pregnancy (or willingness to become pregnant during the study) or breast-feeding during study period;
16. Has an intellectual incapacity or inability to comprehend, precluding adequate understanding or co-operation.
