Item 5. Other Events
Enzon, Inc. announced that results from a Phase III clinical trial
comparing the safety and efficacy of PEG-INTRON(TM) (peginterferon alfa-2b)
Injection and INTRON(R) A (interferon alfa-2b, recombinant) Injection, as
monotherapy for the treatment of hepatitis C will be presented by study
investigators at the upcoming European Association for the Study of the Liver
(EASL 2000) annual meeting on May 1, 2000. These results were reported in a
study abstract, posted on http://www.easl.com. In this study, after 48- weeks of
treatment plus a 24-week follow-up period, 25% of the patients treated with a
once weekly dose of ug/kg of PEG-INTRON showed a sustained viral response as
compared to 12% of patients receiving INTRON A three times a week. The trial
also concluded that PEG-INTRON was as safe as INTRON A. Preliminary Phase II
clinical results of PEG-Intron and REBETOL Combination Therapy will also be
presented by study investigators.
Schering-Plough Corporation currently markets INTRON A, for hepatitis B and
C and various cancers, and REBETRON(TM), a combination of INTRON A and
REBETOL(R) (ribavirin) capsules, for hepatitis C. Schering-Plough has reported
that the 1999 aggregate worldwide sales of INTRON A/REBETRON were approximately
$1.1 billion.
Monotherapy with PEG-INTRON may provide an alternative treatment to
hepatitis C patients who currently cannot tolerate REBETRON Combination Therapy.
Schering-Plough, in February 2000, announced that the European Union (EU)
Committee for Proprietary Medicinal Products (CPMP) of the European Agency for
the Evaluation of Medicinal Products (EMEA) issued an opinion recommending
approval of PEG-INTRON for hepatitis C. Product approval by the EMEA is
typically issued three months from the time that the Committee renders its
opinion. Approval of this application for PEG-INTRON will allow Schering-Plough
the market PEG-INTRON throughout the European Union. In December 1999,
Schering-Plough submitted a Biologics License Application, or BLA, to the FDA
seeking marketing approval for PEG-INTRON for the treatment of chronic hepatitis
C.
