E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective is to initiate a secondary hormone ablation with somatostatin analogues for patients with hormone-refractory prostate cancer following radical prostatectomy without computer tomographic or skeletal scintigraphic confirmed manifest metastatic lesions. Primary criteria:
• PSA Response Assessment of the PSA (Prostate Specific Antigen) -based response (PSA-R) of patients with homone-refractory prostate cancer without evidence of manifest metastatic lesions receiving intramuscular somatostatin-analogue treatment.
• CgA Response Assessment of the CgA (Chromogranin A) -based response (CgA) of patients with hormone-refractory prostate cancer without evidence of manifest metastatic lesions receiving intramuscular somatostatin-analogue treatment.
|
|
E.2.2 | Secondary objectives of the trial |
-Biological effects -chromogranin A (CgA) in serum -Insulin-like growth factor (IGF-1) in serum -Overall survival -Assessment of safety and feasibility of a somatostatin-analogue therapy in patients with prostate cancer.
Experimental study aims
- Correlation of therapeutic response of a reduction of PSA or CgA with expression of PSA, CgA, AR and NeuroD1 in primary tissue.
The aim of this study is to demonstrate the feasibility and safety together with the optimisation of efficacy of the described therapy in patients with biochemical relapse following radical prostatectomy.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion criteria: • Patients who have given written informed consent prior to the study • Patients with biochemical relapse after radical prostatectomy under hormone ablative therapy using an LHRH analogue, or after surgical castration, with no computer tomographic or skeletal scintigraphic evidence of manifest metastatic lesions. • Serum testosterone < 1.75 nmol/l • Karnofsky index > 70 • Age >40 /< 90 • No previous or concomitant chemotherapy ( Exception: hormone therapy) • No concomitant radiotherapy • Clinical chemistry: essentially normal values for liver, pancreas and kidney function (bilirubin < UNL mg/dl, creatinine < 1.5x UNL mg/ dl, amylase and lipase within normal range) • No chronic obstructive lung disease or other allergic predisposition from medical history
|
|
E.4 | Principal exclusion criteria |
• Karnofsky index < 70 • Patients unwilling to give written informed consent to study participation • Previous pancreatic illness e.g. pancreatitis • Alcohol abuse • Obstructive lung disease or known allergic predisposition • Presence of an uncured second malignant disease • Intake of drugs which hinder functioning of the immune system • Previous chemotherapy • Concomitant radiotherapy • Cerebral seizures • Severe physical or psychological concomitant diseases which could impair the compliance of the patient to study protocol procedures or the evaluation of drug safety, e.g. clinically relevant ascites, cardic insufficieny> NYHA III, clinically relevant ECG anomalies • Intake of other study medication within 30 days prior to randomisation.
