Avemar (MSC) is a nontoxic fermented wheat germ extract demonstrated to have antitumor effects. Avemar has the potential to significantly improve the survival rate in patients suffering from malignant colon tumors. We studied its effects in the HT-29 human colon carcinoma cell line. Avemar had an inhibiting effect on colonies of HT-29 cells with an IC50 value of 118 microg/ml (7 days of incubation); this value could be decreased to 100 and 75 microg/ml in the presence of vitamin C. In the cell line examined, Avemar induced both necrosis and apoptosis, as demonstrated by Hoechst/propidium iodide staining. The incubation of cells with 3200 microg/ml Avemar for 24 hrs caused necrosis in 28% and the induction of apoptosis in 22% of the cells. Avemar inhibited the cell-cycle progression of HT-29 cells in the G1 phase of the cell cycle. In addition, Avemar inhibited the activity of the key enzyme of de novo DNA synthesis, ribonucleotide reductase. In addition, we determined the effects of Avemar on the activity of cyclooxygenase-1 and -2. Both enzymes were significantly inhibited by Avemar with IC50 values of 100 and 300 microg/ml, respectively. We outline new explanations for its antitumor activity, which might serve as the basis for further studies using Avemar.

The role of the product in the treatment of colorectal cancer is reviewed in the light of experimental and clinical results to date. The fermented wheat germ extract (code name: MSC, trade name: Avemar) registered as a dietary food for special medical purposes for cancer patients to complement the active oncotherapy, exerted a growth inhibitory effect in HCR-25 human colon carcinoma xenograft, and had a synergistic effect with 5-FU in mouse C-38 colorectal carcinoma. The product is capable of chemoprevention of colon carcinoma in F-344 rats. One of the most significant underlying mechanism is a highly cancer cell specific induction of caspase-3 mediated cleavage of PARP. In the frame of supportive therapy, fermented wheat germ extract proved to be efficient in the treatment of colorectal cancer in humans.

Effect of Avemar–a fermented wheat germ extract–on rheumatoid arthritis. Preliminary data.

Fourth Department of Rheumatology, National Institute of Rheumatology and Physiotherapy, Budapest, Hungary.

OBJECTIVE: To investigate the effect of the fermented wheat germ extract (Avemar)in patients with severe rheumatoid arthritis (RA). METHODS: Fifteen female RA (Steinbrocker II-III) patients, who had unsuccessfully tried two different DMARD treatments, were enrolled in an open-label, 1-year long, pilot clinical study. DMARD and steroid therapies were recorded and continued. All patients received Avemar as additional therapy. For measurement of efficacy the Ritchie Index, the Health Assessment Questionnaire (HAQ) and the assessment of morning stiffness were applied.

Avemar, a nontoxic fermented wheat germ extract, induces apoptosis and inhibits ribonucleotide reductase in human HL-60 promyelocytic leukemia cells.

Clinical Institute of Medical and Chemical Laboratory Diagnostics, Medical University of Vienna, General Hospital of Vienna, Waehringer Guertel 18-20, A-1090 Vienna, Austria.

Avemar (MSC) is a nontoxic fermented wheat germ extract demonstrated to significantly improve the survival rate in patients suffering from various malignancies. We investigated its effects in human HL-60 promyelocytic leukemia cells. After 24, 48, and 72 h of incubation, Avemar inhibited the growth of HL-60 cells with IC50 values of 400, 190, and 160 microg/ml, respectively. Incubation with MSC caused dose-dependent induction of apoptosis in up to 85% of tumor cells. In addition, Avemar attenuated the progression from G2-M to G0-G1 phase of the cell cycle and was also found to significantly reduce the in situ activity of ribonucleotide reductase, the key enzyme of de novo DNA synthesis. We conclude that Avemar exerts a number of beneficial effects which could support conventional chemotherapy of human malignancies.

“Avemar pulvis” is a powder consisting of an aqueous extract of fermented wheat germ, with the drying aids maltodextrin and silicon dioxide, standardized to contain approximately 200 mug/g of the natural constituent 2,6-dimethoxy-p-benzoquinone. The results of toxicological and clinical studies of this product demonstrate its safety for its intended use as a dietary supplement ingredient in the United States. Avemar pulvis has been used in Hungary since 1998 and is approved in that country, as well as in the Czech Republic, Bulgaria, and Romania, as a “medical nutriment for cancer patients.” Acute and subacute toxicity studies using rodents orally administered Avemar pulvis showed that dose levels (2000 to 3000 mg/kg body weight [bw]/day) exceeding the normal recommended oral dosage (8.5 g/day or 121 mg/kg bw/day for a 70-kg individual) by up to approximately 25-fold caused no adverse effects. The test substance showed no evidence of mutagenicity or genotoxicity in vitro or in vivo. Clinical studies using Avemar pulvis as a supplement to drug therapy in cancer patients at doses of 8.5 g/day not only showed no evidence of toxicity, but also showed a reduction in the side effects of chemotherapy. Overall, it was concluded that Avemar pulvis would not be expected to cause adverse effects under the conditions of its intended use as an ingredient in dietary supplements.
