|Study Design:||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Prospective, Open Phase I Study to Investigate the Tolerability and Efficacy of Administering ALECSAT to Prostate Cancer Patients - a First Dose in Man Study|
- The primary endpoint is to show safety and tolerability for the administration of ALECSAT to enable further clinical development of the ALECSAT therapy. [ Time Frame: Within 7 weeks ] [ Designated as safety issue: Yes ]
- The secondary endpoint for this study is to establish if any indications of a positive therapeutic effect on the prostate cancer may be observed. [ Time Frame: Within 7 weeks ] [ Designated as safety issue: No ]

This study is a prospective open phase I study to investigate the safety and tolerability of administration of a single dose of a cell based medicinal product (CBMP) ALECSAT.
ALECSAT is an autologous CBMP that is made from the patient's own blood cells. ALECSAT contains a large amount of tumour specific cytotoxic Lymphocytes (CTL) and Natural Killer (NK) cells that are isolated activated and amplified in number.
The CBMP is given as a slow i. v. injection to patients with prostate cancer. The patients are in the late stage of the disease where they have received hormone treatment but their disease is progressing.
The primary objective of the study is to observe if any side effects or tolerability issues occur as a consequence of the cell administration, secondarily it will be observed if any positive anti tumour effect may be observed. The study has the purpose to investigate whether treatment with ALECSAT in any way is toxic.
Trial Design: The study is an open, prospective phase I safety study of ALECSAT in prostate cancer patients.
A group consisting of 6 patients will be treated with ALECSAT according to the protocol. Then an interim analysis will be done. If there are no signs of significant toxicity related to the treatment, the study will continue with 8 more patients that will be included and treated with ALECSAT according to the phase I protocol. Thus this study will include a total of 14 patients.
The patients will after a single administration of ALECSAT be hospitalised for 3 days and will furthermore be followed closely for 7 weeks by 5 planned study visits, by the investigators at Urologisk Klinik at Fredrikssund Hospital.
