Memorial Sloan
Kettering Cancer
Center ("MSKCC") has announced at the
Annual Meeting of American Society of Clinical Oncology (ASCO) in Chicago May 30 - June 3,
2008, the results of a government-funded clinical study which began in 2004 and
confirms the immunomodulatory effects of Maitake extracts as well as "no
dose-limiting toxicity". MSKCC also
concluded that the clinical significance is unknown yet. The study was conducted on a crude
extract from maitake mushroom (Grifola frondosa). MSKCC together with Cornell University
Medical College published in 2004 the result of another laboratory study that
showed a significant enhancement of bone marrow colony formation as well as the
reduction of toxicity induced by an anti-cancer drug by the crude Maitake extract.(*)
Mike Shirota, CEO of Maitake Products, Inc.
welcomes the study by saying, "Our Grifron®-Pro Maitake D-Fraction® has
already been under a clinical trial with advanced breast and prostate cancer
patients under Investigational New Drug (IND) approval by the FDA. The new
clinical study at MSKCC, one of the nation's most prominent cancer institutes,
will significantly strengthen scientific validation of Maitake extracts,
although it was not carried out on a purified and standardized extract like our
Grifron® Pro Maitake D-Fraction®." Maitake Products,
Inc. is an official Corporate Cancer Research Sponsor of the Memorial Sloan
Kettering Cancer
Center.
