Protein Sciences Announces Completion of Targeted Enrollment of Subjects in a Phase II/III Clinical Trial of FluBlok(TM), its Patented Cell Culture Influenza Vaccine

    MERIDEN, Conn., Nov. 22 /PRNewswire/ -- Protein Sciences Corporation, a
 world leader in developing the next generation of safer, more effective human
 and veterinary vaccines, announced today that it completed enrollment of 460
 subjects in a Phase II/III proof of principle/field study of FluBlok(TM), its
 patented cell culture influenza vaccine.  The study is comparing two different
 doses of FluBlok to a placebo group.  The study sites are the University of
 Rochester, NY (Dr. John Treanor, Study Principal Investigator), the University
 of Cincinnati Children's Hospital (Dr. Gilbert Schiff) and the University of
 Virginia (Dr. Frederick Hayden).
     Daniel D. Adams, President and CEO of Protein Sciences stated, "We believe
 that as enrolled the trial we will not only achieve our primary endpoint --
 showing safety and establishing a commercial dose for FluBlok -- but also will
 show by statistically significant data that FluBlok protects against influenza
 under field conditions as well or better than licensed vaccines."
