E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the pharmacodynamic profile of a 6-month sustained-release formulation of triptorelin administered as two simultaneous subcutaneous microimplant injections (2x6 mg) by measuring serum testosterone levels. |
|
E.2.2 | Secondary objectives of the trial |
•To determine the proportion of patients achieving medical castration (defined as serum testosterone level <50 ng/dL) at Day 31; •To determine the proportion of patients maintaining medical castration on Day 181; •To evaluate the pharmacodynamic profile/efficacy by measuring LH, FSH and PSA serum levels; •To evaluate the pharmacokinetic profile by measuring plasma triptorelin levels; •To assess the clinical and biological tolerance of the simultaneous subcutaneous administration of the 2x6 mg microimplant formulation; •To document the potential testosterone flare at the time of the 1st and the 2nd triptorelin administration; •To determine the proportion of patients medically castrated (defined as serum testosterone level <50 ng/dL) on Day 361.

E.3 | Principal inclusion criteria |
All screened patients must fulfil the following: 1) Give written (personally signed and dated) informed consent before completing any study-related procedure; 2) Be 18 years old or over; 3) The patient must have a histologically-confirmed diagnosis of prostate cancer, either locally advanced or metastatic or a biological and/or clinical relapse after a curative treatment like radical prostatectomy, external radiotherapy or curietherapy amenable to androgen deprivation therapy; 4) Have a life expectancy of at least twelve months; 5) Have WHO ECOG performance status score < ou = 2;

E.4 | Principal exclusion criteria |
A screened patient will not be included in the study if he: 1) Has undergone a surgical castration; 2) Has undergone any surgery for prostate cancer within 2 weeks of baseline; 3) Has undergone radiation therapy for prostate cancer within 2 months of baseline; 4) Has undergone hormone therapy (GnRH analogue, oestrogens or steroid anti-androgens) within 3 months of baseline (previous treatment with non-steroidal anti-androgens is permitted) or could be under the effects of any hormonal therapy; 5) Has undergone any of the following treatments for prostate cancer within 2 months of baseline: immunotherapy, chemotherapy, biological response modifiers (cytokines); 6) Was treated with any other investigational medicinal product (IMP) within the last 90 days before study entry; 7) Was treated with over-the-counter or alternative medical therapies that have an oestrogenic or anti-androgenic effect within the three months of baseline; 8) Has a risk of a serious complication in the case of tumour flare (vertebral metastases threatening spinal cord compression or significant obstructive uropathy); 9) Has a serum testosterone level below 150 ng/dL at screening; 10) Has a history of hypersensitivity to the IMP or drugs with a similar chemical structure; 11) Has any condition that may preclude subcutaneous injection; 12) Presents with known brain metastasis or leptomeningeal involvement; 13) Presents with other serious illness or medical condition; - Active or uncontrolled infection, - Any medical condition that might be aggravated by treatment or which could not be controlled: patients with concurrent heart failure New York Heart Association (NYHA) class III-IV or patients with severe/unstable angina pectoris, patients with myocardial infarction within 6 months, patients with history of cerebrovascular disease, and/or poorly controlled hypertension, patients who experienced venous thrombosis within six months of baseline, or have hypercalcaemia (calcium >2.9 mmol/L); 14) Has received a diagnosis of any other cancer, without a history of stability/remission, within 5 years of screening, with the exception of non-metastatic basal and/or squamous cell carcinoma of the skin; 15) Is, in the opinion of the Investigator, unable to comply fully with the protocol and the study instructions, or presents any concomitant condition which could compromise the objectives of the study and/or preclude the protocol-defined procedures (e.g. psychological, familial, sociological or geographical conditions). 16) Have inadequate blood parameters; Granulocytes < or = 2.0x10^9/L, Platelets < or = 100x10^9/L, Haemoglobin < 9 g/dL, 17) Have normal hepatic function; Bilirubin >1.5xUNL, ASAT/ALAT >2.5xUNL (and >5xUNL if liver metastasis), Alkaline phosphatase >2.5xUNL (and >5xUNL if liver or bone metastasis), 18) Have normal renal function; Creatinine >1.5xUNL.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the pharmacodynamic profile derived from testosterone serum levels. Specifically, Tlag, the time to achieve castration (testosterone levels <50 ng/dL) in days post-treatment; Texit, the time to escape from castration (testosterone levels ≥50 ng/dL); and Tcast the duration of castration. |
