Brief Summary:
This study is a phase I study of a cell based prostate cancer therapy, Autologous Lymphoid Effector Cells Specific Against Tumor-cells (ALECSAT). Safety and tolerability of a single dose has been shown in 13 prostate cancer patients. In this study 20 prostate cancer patients will receive 3 doses of the ALECSAT treatment. In this therapy specific cells from the patient's own immune system are isolated, activated and re-administered to the patient to boost a specific immune response against the cancer cells. The aim of the study is to show safety and tolerability for repeated dosing of this type of therapy. It is the hypothesis that the cells administered during the therapy will attack the tumor cells and in this way stop or slow down the progression of disease.
Detailed Description:
This study is a prospective open phase I study to investigate the safety and tolerability of administration of repeated doses 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 repeated administration of ALECSAT, secondarily it will be observed if changes in Prostate-Specific Antigen (PSA) levels or any positive anti tumor effect may be observed. The study has the purpose to investigate whether repeated 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 4 patients will be treated twice 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 to the third treatment for these patients and with 14 more patients that will be treated with ALECSAT according to the protocol. Thus this study will include a total of 20 patients.
The patients will after the first administration of ALECSAT be hospitalized for 2 days. Five and 10 weeks later the patients will be hospitalized for 1 day and receive the second and third administration of ALECSAT. Each patient will furthermore be followed closely for 12 weeks after the third treatment. During the course of the entire study the patients will be monitored by 11 planned study visits, by the investigators at Department of Urology, Fredrikssund Hospital, Denmark.
