Trial Description
Title
Prostagen Study - Investigation of polymorphisms in genes of the fatty acid
metabolism in relation to the evolvement and further development of prostate
cancer

Brief Summary in Lay Language
The aim of this study is to develop a genetic test able to predict the individual
course of disease (aggressiveness) in patients with prostate cancer. An accurate
prediction could allow a better decision on the most suitable treatment for the
individual patient.
It will also seek to clarify if a supplementation with omega-3 fatty acids in form of
marine phospholipids (Vitalipin ® capsules) could achieve a reduction of prostate
specific antigen (PSA) in the blood.
Brief Summary in Scientific Language
The primary study objective is to determine polymorphisms (SNPs) in genes of the
fatty acid metabolism and its possible correlation with the incidence of prostate
cancer, as well as with the severity of the disease.
A secondary objective is to examine changes in the fatty acid composition in blood
samples after an intake of omega-3 fatty acids in form of phospholipids over a
period of three months (as dietary supplementation) and whether these changes
depend on the individual SNPs constellation.
Based on the results of this research, an improved decision regarding therapy
and/or dietary recommendations (in relation to omega-3-fatty acids) the most
suitable for each patient, could be created.

Primary Outcome
Analysis of polymorphisms (SNPs) in genes of the fatty acid metabolism will be
done to each patient / healthy subject at the beginning of the study.
Secondary Outcome
To assess changes in the fatty acid composition in plasma after the
supplementation with the omega-3-preparation and its relation to the found SNP.
Phospholipids, lysolipids and their fatty acid composition in plasma at baseline
and after three months of omega-3-intake will be analyzed.
