E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To characterize the goserelin plasma concentration profile based on primary pharmacokinetic endpoints from Day 1 to 29 of Period 1 and Day 1 (coinciding with Day 29 of Period 1) to Day 17 of Period 2 (2 treatment cycles whereas Day 29 of Period 2 represents the end of treatment), after 2 consecutive injections with Zoreline 3.6 mg or Zoladex® 3.6 mg subcutaneous implant in female subjects with confirmed endometriosis. |
|
E.2.2 | Secondary objectives of the trial |
-To characterize additional PK parameters: gosereline plasma concentration at the end of the first treatment cycle[CDay29 of Period 1] and 17 days post-second implant injection [CDay17 of Period 2]; time to reach Cmax [tmax]. -To assess the general safety and acceptability of the drug in both groups.

E.3 | Principal inclusion criteria |
1. Women aged between 18 and 45 years (inclusive), who are not menopausal. 2. Clinical diagnosis of endometriosis, within the last 5 years indicated for treatment with hormone therapy as judged by the investigator. Note: As per clinical guidelines: Clinical diagnosis is be based on clinical symptoms of endometriosis (such as chronic pelvic pain, dyspareunia, cyclic intestinal pain (bloating/diarrhoea/constipation), uterine cramping in young females, severe dysmenorrhea, dyspareunia, ovulation pain, cyclical/menstrual symptoms with or without abnormal bleeding, infertility, chronic fatigue) confirmed by laparoscopy (with or without histology) and/or transvaginal/rectal ultrasound (bladder, ovarian or rectum locations) and/or enema studies (for deeply infiltrating endometriosis). 3. Good physical and mental health as judged by the investigator determined by medical history, physical examination, clinical laboratory and vital signs. 4. Willing to give informed consent in writing. 5. Willing to use non-hormonal anti-conception from screening visit till the end of treatment (Day 29 of Period 2). 6. Willing and able to attend the scheduled study visits and to comply with the study procedures. 7. Body Mass Index (BMI) between 18 and 32 kg/m2 inclusive. |
|
E.4 | Principal exclusion criteria |
1. Previous or current hormonal treatment for endometriosis: including usage of GnRH receptor agonists or GnRH receptor antagonists within 6 months prior to the screening visit. 2. Use of treatments that interfere with estradiol plasma level within one week (or 5 half-lives, whichever is longer) before drug administration. 3. Endometriosis surgery scheduled in the period between screening and end of study. 4. Alanine aminotransferase (ALT)/ serum glutamic-pyruvic transaminase (SGPT) or aspartate transaminase (AST) / serum glutamic oxaloacetic transaminase (SGOT) levels ≥ 2x upper limit of normal (ULN) or GGT ≥ 2.5 x upper limit of normal. 5. Evidence (including clinically significant abnormal bilirubin and/or albumin values) or history for chronic hepatic disease. Gilbert’s disease however is allowed. 6. Moderate or severe chronic kidney disease with an estimated glomerular filtration rate (eGFR), calculated by using the modification of diet in renal disease (MDRD) equation, < 60 mL/min/1,73m2. 7. Use of implanted long-acting progestin treatments like nexplanon or implanon at less than 1 month before the screening visit. 8. Receipt of an investigational drug within the last 28 days before the Screening visit (or 5 times the half-life of the drug, whichever is longer), if considered by the investigator to possibly influencing the outcome of this trial. 9. An unstable medical condition or chronic disease (including history of neurological [including cognitive and untreated depression], cardiovascular [including uncontrolled hypertension], gastrointestinal, pulmonary, bone, metabolic or endocrine disease), or malignancy that could confound interpretation of the study at investigator’s discretion. 10. History of severe uncontrolled asthma, anaphylactic reactions, or severe urticarial and/or angioedema, and particularly, history of hypersensitivity towards any components of the study drug. 11. History or presence of any malignancy other than treated squamous cell/basal cell carcinoma within the last 5 years. 12. Loss in bone mass that could affect the patient's health. 13. Prolonged QTc interval defined as mean QTcF > 450 ms at Screening or on Day 1 of Period 1 as measured by triplicate ECG. Note: If the mean value of the QTcF interval from the three measurements is above 450 ms, another triplicate ECG should be recorded once. 14. Family history for prolonged QT interval including history of arrhythmia, sudden unexplained death at a young age (before 40 years) in a first-degree relative. 15. Patients with unstable angina pectoris or stable angina pectoris classified higher than Canadian Cardiovascular Society Class II, or a myocardial infarction, or stroke within 6 months before Visit 1 ( Screening visit ). 16. History of hospitalization within 12 months before Visit 1 (Screening visit) caused by heart failure or a diagnosis of heart failure higher than New York Heart Association Class II. 17. Patient with decompensated diabetes mellitus. 18. Other abnormal laboratory results, which according to the investigator would affect the patient's health or the outcome of the trial. 19. Pregnancy (or willingness to become pregnant during the study) or breast-feeding. 20. Intellectual incapacity or inability to comprehend, precluding adequate understanding or co-operation. 21. Any contraindications for goserelin administration. |
