Brian Frenzel’s current day-to-day responsibilities include serving on the board of directors of SanBio, Inc. in Mountain View, CA and as President and CEO of Tosk, Inc., in Santa Cruz, CA. SanBio develops new cell therapies to recover function in disabled neurodegenerative disease patients, tapping into Mr. Frenzel’s extensive experience in this field. SanBio’s first product, for recovery of motor and cogitative function in patients who have suffered ischemic stroke is currently undergoing clinical studies in the United States. SanBio has other therapies under development for Parkinson’s disease, retinal disorders, multiple sclerosis and muscular dystrophy. Tosk, Inc. develops new oncology drugs, with a focus on discovering and developing drugs that block dose-limiting, potentially fatal adverse side effects of chemotherapeutic agents and radiation therapy. Tosk’s first drug for amelioration of mucositis, a painful and debilitating adverse effect of a number of cancer therapies, has recently completed the first phase of human clinical studies. It, along with related compounds and technologies, was claimed in a recently awarded U.S. patent for which Mr. Frenzel was a co-inventor.
