Dr. Arnold Monto to Help Evaluate and Advance Tarvacin(TM) Anti-Viral as a
Potential Treatment for Common and H5N1 Avian Influenza Strains -
- Tarvacin Already in Human Trials for Hepatitis C and Cancer -
TUSTIN, Calif., Nov. 30 /PRNewswire-FirstCall/ -- Peregrine
Pharmaceuticals, Inc. (Nasdaq:
PPHM), a biopharmaceutical company with a
portfolio of innovative, clinical stage product candidates for viral diseases
and cancer, today announced that it has appointed noted influenza expert
Arnold S. Monto, M.D., professor of epidemiology at the School of Public
Health of the University of Michigan, to its Scientific Resource Board.
Dr. Monto's expertise in influenza will support further evaluation of
Peregrine's clinical stage drug, Tarvacin(TM) Anti-Viral, for the treatment of
influenza, including the H5N1 avian influenza strain. Tarvacin Anti-Viral is
in a Phase I clinical trial for the treatment of chronic hepatitis C infection
and is being studied preclinically for use in the treatment of cytomegalovirus
and HIV, as well as influenza infections.
"Dr. Monto is one of the leading influenza experts in the world, and his
expertise should be especially valuable to Peregrine as we accelerate our
efforts to assess Tarvacin as a potentially important new influenza therapy,"
said Steven King, president and CEO of Peregrine. "As we have previously
reported, Tarvacin Anti-Viral binds to members of six different virus
families, including common influenza strains, and we are expanding our
existing collaborations with federal, private and academic research centers to
evaluate Tarvacin in animal models as both a stand-alone agent and in
combination with existing influenza therapies."
Tarvacin is a monoclonal antibody with unique anti-viral properties. It
attaches to specific cellular components called phospholipids found on the
surface of virus particles, including influenza and certain other virus
strains, as well as on the outer surface of human host cells only when they
are infected with these viruses. Tarvacin helps stimulate the body's natural
immune defenses to destroy both the virus particles and the infected cells.
Since the targeted phospholipids are not exposed on healthy cells, they are
not affected by Tarvacin, which in studies to date appears to be safe and well
tolerated. In addition, because Tarvacin's target is derived from the
infected human cell, its efficacy is less likely to be affected by mutations
in the virus, an issue that has led to drug resistance with other anti-viral
medications.
In preclinical studies Tarvacin has shown encouraging activity both as a
stand-alone agent and in combination with existing drugs. In addition, it has
the potential for broad activity against most types of influenza virus
strains, regardless of the specific genetic make-up of the virus itself.
"Tarvacin Anti-Viral has a unique and intriguing mechanism of action
supported by interesting science, and I look forward to helping to fully
evaluate its potential as a possible new therapy for influenza," said
Dr. Monto. "I am on record as stating that a flu pandemic is inevitable at
some point, so it is essential that we be prepared with a full arsenal of
preventative and therapeutic measures. Tarvacin may prove to be a promising
new therapeutic option in the anti-viral arena, and I look forward to
contributing to its progress."
Dr. Monto's influenza research is supported by grants from the National
Institutes of Health and the Centers for Disease Control. In January of this
year he authored an article on the threat of an avian flu pandemic in the New
England Journal of Medicine. Dr. Monto currently consults with a number of
federal agencies on influenza prevention, treatment and preparedness.
Among his many honors and special appointments, Dr. Monto is currently
finishing a term as president of the American Epidemiological Society, and he
has served as director of the University of Michigan's Bioterrorism
Preparedness Initiative, as chairman of its Department of Population Planning
and International Health, as a scholar-in-residence at the National Academy of
Sciences and Institute of Medicine, in the Division of Communicable Diseases
at the World Health Organization, and as a staff member in the Virus Disease
Section of the National Institute of Allergy and Infectious Diseases. Dr.
Monto has authored numerous scientific publications on influenza and other
public health issues. He received his undergraduate and M.D. degrees from
Cornell and completed a post-doctoral fellowship in infectious diseases at
Stanford.
In addition to its anti-viral properties, Tarvacin also binds to
phospholipids exposed on tumor blood vessels in all solid cancers tested to
date. Tarvacin Anti-Cancer is currently in a multi-center Phase I clinical
trial for patients with advanced refractory solid tumors.
