FibroGen Appoints David Y. Liu, Ph.D., Vice President, Research
South San Francisco, Calif. - January 22, 2003 - FibroGen,
Inc., a privately held biotechnology company, today announced the
appointment of David Y. Liu, Ph.D., Vice President, Research. Dr. Liu
will focus on the rapid advancement of FibroGen's small molecule and
therapeutic antibody programs towards the development stage. FibroGen's
therapeutics business is centered on the discovery and development
of novel drugs that target Connective Tissue Growth Factor (CTGF)
and various prolyl hydroxylase enzymes for the treatment of diseases
and medical conditions associated with fibrosis (excessive scarring)
and ischemia (reduced blood flow to an organ or tissue), respectively.
Dr. Liu joins FibroGen from Scios, Inc., where he was the Director of
Inflammation Research and project leader for Scios' first two kinase
inhibitor programs. Under his direction, new chemical entities
with novel mechanisms of action were discovered and are progressing
through preclinical and clinical development. Prior to his tenure
at Scios, Dr. Liu held scientist positions at COR Therapeutics and
Cetus Corporation, leading projects to investigate inflammation and
leukocyte adhesion inhibitors.
"Dr. Liu brings to FibroGen a successful track record in drug discovery
and development, and we expect him to play a key role in fostering the
continued growth of our therapeutics business," said Thomas B. Neff,
Chairman and Chief Executive Officer. "Our prolyl hydroxylase and CTGF
programs have already yielded two lead drug candidates in preclinical
development. Dr. Liu's contributions are expected to help us to fully
develop the wide potential of these therapeutic platforms."
Dr. Liu also held a research position as an associate immunologist in
the Department of Rheumatology at the Brigham and Women's Hospital,
Boston, MA, and was an instructor and assistant professor of Medicine at
the Harvard Medical School. He is an author of over fifty-two original
research reports and reviews and a named inventor on thirteen patents
or patent applications, as well as an editor of Adhesion: Its Role in
Inflammatory Disease (1992). Dr. Liu earned a Ph.D. in Microbiology
and Immunology from Michigan State University and a B.S. in Chemistry
from the University of Chicago.
