INSUFFICIENT RELIABLE EVIDENCE to RATE

• Chemotherapy-related infection. It is unclear if oral fermented wheat germ extract is effective for the prevention of febrile neutropenia in children receiving chemotherapy. Details: A small, open-label clinical study in children undergoing chemotherapy shows that a specific fermented wheat germ extract (Avemar) 6 grams/m2 dissolved in water and taken by mouth twice daily along with standard chemotherapy for an average of 10-11 chemotherapy cycles (approximately 29 months) reduces the frequency of febrile neutropenia when compared with chemotherapy alone. Thirty episodes of febrile neutropenia were reported for children receiving fermented wheat germ extract, compared to 46 episodes reported for children receiving chemotherapy alone (27702).
• Colorectal cancer. It is unclear if oral fermented wheat germ extract is beneficial in patients with colorectal cancer. Details: Small non-randomized, open-label clinical studies in patients with colorectal cancer show that taking a specific fermented wheat germ extract (Avemar) 9 grams once or twice daily for at least 6 months in addition to chemotherapy reduces colon cancer progression, the frequency of new metastases, and the risk of mortality when compared with chemotherapy alone (27703,27704). The validity of these findings is limited by a lack of randomization and blinding.
• Melanoma. It is unclear if oral fermented wheat germ extract is beneficial in patients with melanoma. Details: A small clinical study in patients with melanoma shows that a specific fermented wheat germ extract (Avemar) 8.5 grams mixed in a drink and taken once daily in addition to dacarbazine (DTIC)-based chemotherapy for 12 months increases overall survival after 7 years of follow-up by around 22 months and progression-free survival by around 26 months when compared with dacarbazine (DTIC)-based chemotherapy alone (27707).
• Prostate cancer. It is unclear if oral fermented wheat germ extract is beneficial in patients with prostate cancer. Details: A small clinical study in patients with castration-resistant prostate cancer shows that a specific fermented wheat germ extract (Avemar) 8.5 grams mixed in a drink and taken once or twice daily in addition to a gonadotropin releasing hormone analog for at least 4 months increases the doubling time for prostate specific antigen levels in most patients, but does not seem to improve quality of life, when compared to baseline (109632). The validity of these findings is limited by a lack of control group.
• Rheumatoid arthritis (RA). It is unclear if oral fermented wheat germ extract is beneficial in patients with RA. Details: A small, uncontrolled clinical study in females with RA shows that taking a specific fermented wheat germ extract (Avemar) 8.5 grams by mouth in a drink twice daily in addition to disease-modifying anti-rheumatic drug (DMARD) and steroid therapies for 12 months reduces morning stiffness and the dose of steroid drug needed when compared to baseline (27706). The validity of these findings is limited by a lack of control group.
• Systemic lupus erythematosus (SLE). Although there has been interest in using oral fermented wheat germ extract for SLE, there is insufficient reliable information about the clinical effects of fermented wheat germ extract for this purpose. More evidence is needed to rate fermented wheat germ extract for these uses.

POSSIBLY SAFE ...when used orally and appropriately. A specific fermented wheat germ extract (Avemar) has been used safely in clinical research at doses of 8.5-9 grams once or twice daily for up to 12 months (27703,27704,27706,27708,109632). There is insufficient reliable information available regarding the safety of fermented wheat germ extract when applied topically.

CHILDREN: POSSIBLY SAFE
when used orally and appropriately. A specific fermented wheat germ extract (Avemar) has been used safely in clinical research at a dose of 6 grams/m2 twice daily for approximately 29 months (27702).

PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.

IMMUNOSUPPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, fermented wheat germ extract might decrease the effects of immunosuppressants.  Details Animal research suggests that fermented wheat germ extract can stimulate immune function (27709,27712,27713,27714,27727).

General ...Orally, fermented wheat germ extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, nausea.

Gastrointestinal ...Orally, fermented wheat germ extract may cause diarrhea, nausea, flatulence, satiation, soft stools, and constipation. In one clinical study, diarrhea and nausea with or without vomiting were reported in 6% and 3% of patients, respectively (27703).
