E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to assess the ability of Zoreline 10.8 mg SC implant to induce by Day 29 of Cycle 1 at the latest and maintain up to Day 85 of Cycle 2 (end of treatment) testosterone plasma suppression (≤50 ng/dL) in male patients with prostate cancer. |
|
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 (Tmax, Cmin, Cmax, AUC) from Day 1 to Day 85 in each treatment cycle, i.e. during two consecutive treatment cycles in which Day 85 represents the end of treatment of each cycle. 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 testosterone plasma concentration profile (Cmax, AUC) including initial flare between Day 1 and Day 29 of Cycle 1, time to achieve castration level, acute on chronic phenomenon (surge at re-injection between Day 2 and Day 4 of Cycle 2) and potential escape (surge) following the onset of suppression after the initial flare in Cycle 1 to Day 85 of Cycle 1 (pre-dose Day 1 of Cycle 2) and from Day 8 until Day 85 of Cycle 2 (end of treatment).

2. Scheduled for prostatectomy or radiotherapy during study period
3. ALT (SGOT) or AST (SGPT) ≥2x upper limit of normal (ULN)

5. Has received an investigational drug within the last 28 days before the screening visit or longer if considered by the Investigator to possibly influencing the outcome of this trial
6. History or presence of any malignancy other than treated squamous cell/basal cell carcinoma of the skin within the last five years
7. Have an unstable medical condition or chronic disease (including history of neurological [including cognitive], hepatic, renal, cardiovascular, gastrointestinal, pulmonary, or endocrine disease), or malignancy that could confound interpretation of the study at Investigator discretion
8. 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
9. Other abnormal laboratory results which in the judgment of the Investigator would affect the patient's health or the outcome of the trial
10. Has an intellectual incapacity or language barrier precluding adequate understanding or co-operation |

E.5 End points |
E.5.1 | Primary end point(s) |
Pharmacodynamics:
The primary objective will be considered as achieved if the lower limit of the 2-sided 95% confidence interval (CI) on the responder rate is ≥90%. A responder is defined as a subject who reached plasma testosterone levels below the castrate level (≤50 ng/dL) by Day 29 of Cycle 1 at the latest and maintained plasma testosterone levels below the castrate level (≤50 ng/dL) until Day 85 of Cycle 2 (end of treatment).

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Cycle 1 Day 29 and Cycle 2 Day 85 |
|
E.5.2 | Secondary end point(s) |
Pharmacodynamics:
• Plasma concentrations of testosterone including initial flare between Day 1 and Day 29 of Cycle 1, time to achieve castrate level, acute on chronic phenomenon (surge(s) at re-injection) between Day 2 and Day 4 of Cycle 2 and potential escape (surge) following the onset of suppression after the initial flare in Cycle 1 to Day 85 of Cycle 1 (pre-dose of Cycle 2) and from Day 8 until day 85 of Cycle 2 (end of treatment).
Pharmacokinetics:
• Plasma concentrations of goserelin
Safety:
• Occurrence of serious and non-serious adverse events. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Blood samples will be taken during screening, on day 1, 2, 4, 8, 15, 29, 36 and 57 of cycle 1 and on day 1, 2, 4, 8, 15, 29, 36, 57 and 85 of cycle 2.
Safety:
Adverse events will continuously be monitored from signing of informed consent untill the last study related activity.
