Fermented Wheat Germ Extract (FWGE) as a Treatment Additive for Castration-Resistant Prostate Cancer: A Pilot Clinical Trial

ABSTRACT

Castration-resistant prostate cancer (CRPC) is a devastating and incurable disease. Combined therapy using conventional anticancer drugs and a proprietary medical nutriment, fermented wheat germ extract (FWGE), also known as Avemar, has been suggested as a treatment for progressing prostate cancer (PCa) patients, who have become resistant to first line hormonal therapy (gonadotropin releasing hormone, GnRH). The primary aim of this study was to test if this combined therapy would slow down disease progression in CRPC patients. We tested the nontoxic, readily available, inexpensive FWGE, together with the conventional treatment, GnRH analogue, in 36 CRPC patients. Although this is a pilot study, with the drawback of a statistically small sample size, some anticancer clinical activity of FWGE could be seen in the CRPC patients, as measured by prostate specific antigen doubling time (PSADT). We found that the intake of GnRH with FWGE for at least 4 months, improved the overall health as well as the quality of life (QOL) in 4 patients (11%) and was instrumental in extending the PSADT in about 17 (out of 26) patients (65.4%), six of whom were significant. Since no mentionable adverse events were noticed, this treatment may permit the postponement of chemotherapy for these patients.
