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 85 (1 treatment cycle, Day 85 represents the end of treatment), after injection with Zoreline 10.8 mg or Zoladex® LA 10.8 mg subcutaneous implant in male patients with prostate cancer |
|
E.2.2 | Secondary objectives of the trial |
- To characterize additional PK parameters (plasma concentration at the end of the treatment period [CDay85], time to reach Cmax [tmax]).
- To characterize the testosterone plasma concentration (PD) profile including initial flare between Day 1 and Day 28 and time to achieve castrate level (≤50 ng/dl) after injection with Zoreline 10.8 mg or Zoladex® LA 10.8 mg subcutaneous implant
- To assess general safety and acceptability of the drug in both groups
Exploratory:
• To assess the performance of a novel syringe used to inject Zoreline 10.8 mg subcutaneous implant |

All other prohibited medications that are listed in Appendix 3 should not have been administered within the last 3 months prior the study drug administration
2. Scheduled for prostatectomy or prostate radiotherapy during study period
3. Alanine aminotransferase (ALT) / serum glutamic-pyruvic transaminase (SGPT) or aspartate transaminase (AST) / serum glutamic oxaloacetic transaminase (SGOT) ≥2x upper limit of normal (ULN) or GGT ≥2.5 x upper limit of normal
4. Evidence (including clinically significant abnormal bilirubin and/or albumin values) or history for chronic hepatic disease
Moderate or severe chronic kidney disease with an estimated glomerular filtration rate (eGFR), using the modification of diet in renal disease (MDRD) equation, <60 mL/min/1,73m2
6. Has received 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
7. History or presence of any malignancy other than prostate cancer and treated squamous cell /basal cell carcinoma of the skin within the last five years
8. Have an unstable medical condition or chronic disease (including history of neurological [including cognitive], cardiovascular, gastrointestinal, pulmonary, or endocrine disease), that could confound interpretation of the study at investigator discretion
9. 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
10. Other abnormal laboratory results which in the judgment of the investigator would affect the patient's health or the outcome of the trial
11. Has an intellectual incapacity or language barrier precluding adequate understanding or co-operation
12. Have a prolonged QTc interval defined as mean QTcB > 450 ms at Screening. If the mean value of QTcB interval from the three measurements is above 450 ms, another triplicate ECG could be recorded once on the same day
13. Have a family history for prolonged QT interval including a history of arrhythmia, sudden unexplained death at a young age (before 40 years) in a first-degree relative, or a personal history of syncope
14. Evidence or history for significant active cardiac disease (e.g., congestive heart failure, mitral valve regurgitation, endocarditis, coronary artery heart disease), or symptoms of angina pectoris or transient ischaemic attacks |
