Chief Operating Officer of PharmaCyte Biotech
Gerald Crabtree is the Chief Operating Officer of PharmaCyte Biotech and a Board member. He has spent almost 50 years working in academic, biotech and pharmaceutical companies with the majority of that vast experience being in the development of drugs and treatments for cancer. He has held positions of ever-increasing importance over that time. Crabtree’s background in the biomedical sciences has been substantial, having been involved with various biopharmaceutical companies where he has alternatively supervised and coordinated the development of multiple drug candidates, prepared clinical protocols, investigator brochures, monographs, and research and review articles. A highlight of Dr. Crabtree’s professional career was his tenure as Director of Project Planning and Management (Oncology and Immunology) at Bristol-Myers Squibb (“BMS”) from 1990 to 1997. While at BMS, Crabtree established and directed a department that monitored and coordinated the development of all oncologic and immunologic drugs from initial discovery through regulatory approval within BMS and served as Project Manager for the development of the major anticancer agent, Taxol®, the “number one” drug under development at BMS at that time. Taxol® ultimately became a multi-billion dollar drug for BMS and is still widely used to treat a variety of cancers. From 1989 to 1990, Crabtree was Director of Pharmacology at Viratek, Inc., a subsidiary of ICN Pharmaceuticals, Inc. in Costa Mesa, California. There he worked on the development of anticancer drugs first developed at the Nucleic Acid Research Institute (NARI, a joint venture between Eastman Kodak and ICN Pharmaceuticals) and with ribavirin (Virazole®), Viratek’s landmark antiviral drug. From 1985 to 1989, Crabtree served as Head of the Department of Molecular Pharmacology at NARI where his department was tasked with elucidating the mechanisms of action of anticancer and antiviral drugs developed by NARI chemists. From 1970 to 1985, Crabtree held several faculty positions at Brown University in Providence Rhode Island as well as at the Roger Williams Cancer Center (“RWCC”) at that institution. These positions culminated in his attaining the rank of Associate Professor of Medicine. During his time at Brown and the RWCC, Crabtree studied the mechanisms of action of putative anticancer and antiparasitic drugs and participated in clinical trials of anticancer agents. After leaving BMS in 1997, Crabtree consulted with several biotech companies, all of which were developing cancer drugs or treatments. Then, from 2000 to 2003, Crabtree served as Vice President of R&D at ETEX Corporation, a “device” company, where he was tasked with developing that company’s proprietary calcium phosphate formulations as depot/delivery platforms for cancer drugs. Upon leaving ETEX, he resumed his consulting business, which soon became focused on PhytoCeutica, Inc. located in the Yale Science Park in New Haven, Connecticut, where he assisted in the preparation and review of FDA documents, clinical study protocols, investment acquisitions, and contracts and business plans. PhytoCeutica was developing a traditional Chinese medicine four-herb combination as a treatment for liver and pancreatic cancer. During his time with PhytoCeutica, Crabtree assumed ever-increasing responsibilities and from 2009 to 2010, ultimately serving as its Interim CEO. Dr. Crabtree resumed his consulting business after leaving PhytoCeutica until he joined PharmaCyte Biotech. Crabtree received his Ph.D. in Biochemistry from the University of Alberta, Edmonton, Alberta, Canada, and has published over 80 articles in peer-reviewed journals. He was a National Cancer Institute of Canada Research Fellow. Crabtree is currently a member of the American Society of Clinical Oncology and the American Association for Cancer Research. He has served on research grant review committees for the National Institutes of Health and the American Cancer Society.
