MacroGenics receives multiple government awards totaling more than $62 million to advance infectious disease programs

Rockville, Maryland, October 2, 2006  MacroGenics, Inc. announced today that the National Institute for Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), awarded the privately held biotechnology company a $50 million contract over five years to develop a monoclonal antibody to West Nile virus (WNV). The NIAID contract will support the advancement of the antibody through manufacturing and Phase 2 clinical trials.  MacroGenics WNV antibody is currently in late-stage preclinical testing and is anticipated to enter Phase 1 clinical trials in the first half of 2007.

MacroGenics therapeutic antibody will be targeted to individuals who develop neuroinvasive disease as a result of WNV infection, including patients with meningitis and encephalitis.  Since 1999, 21,877 cases of WNV have been reported to the Centers for Disease Control and Prevention (CDC) and 42% of these reported cases involved neuroinvasive disease.  This year to date, 2,177 WNV cases have been reported to the CDC, a 43% increase in the number of reported cases compared to this time in the 2005 season.  Among infectious pathogens that pose a biothreat or emerging disease risk to the U.S. population, the NIAID has prioritized these agents within three risk categories (A, B, and C).  WNV is assigned to Category B, with those viruses that infect the central nervous system. 

The NIAID award marks a true turning point in the advancement of our infectious disease portfolio, enabling MacroGenics to accelerate the development of a potentially novel, safe and effective intervention for patients suffering from West Nile virus neuroinvasive disease, noted Dr. Scott Koenig, President and CEO of MacroGenics. This award is especially timely, as there currently are no approved treatments for West Nile virus, and there is no evidence that this disease is abating since its introduction in the US in 1999. We are honored to have won the support and confidence of NIAID for this innovative approach to treating infectious diseases. 

MacroGenics also was recently granted two additional awards from NIAID totaling close to $13 million to support two new infectious disease programs. 

The company received a grant of up to $6.8 million to develop a monoclonal antibody with neutralizing activity against smallpox virus in collaboration with investigators at NIAID.  This immunotherapeutic product is intended to prevent infection in the face of an immediate biothreat and to suppress infection and disease in individuals exposed to the smallpox virus. NIAID classifies smallpox as a Category A agent.

MacroGenics was also awarded a NIAID subcontract of up to $6 million from St. Jude Childrens Research Hospital to develop cross-neutralizing monoclonal antibodies specific for the H5N1 influenza virus.  The World Health Organization (WHO) reports that since 2003, there have been 247 cases of human H5N1 avian flu, 58% of which have resulted in death.  New treatments are urgently needed for this virus in the event that person to person spread becomes a major route of virus transmission.
