Item 5. Other Events
Company Announces Submission by Schering-Plough of U.S. Application for
Peg-Intron for the Treatment of Chronic Hepatitis C
Enzon, Inc. (the "Company") announced that on December 23, 1999,
Schering-Plough Corporation submitted a Biologics License Application ("BLA") to
the U.S. Food and Drug Administration seeking marketing approval for PEG-INTRON
(PEG-interferon alfa-2b) Powder for Injection for the treatment of chronic
hepatitis C in patients 18 years of age or older with compensated liver disease.
PEG-INTRON is a modified form of Schering-Plough's INTRON A (interferon alfa-2b,
recombinant) Injection that was developed using the Company's PEG technology to
have longer-acting properties. The application proposes administration of
PEG-INTRON Powder subcutaneously once weekly for one year.
Schering-Plough previously reported that it has submitted a centralized
Marketing Authorization Application for PEG-INTRON to the European Union's
European Agency for the Evaluation of Medicinal Products. Approval of the
centralized Marketing Authorization Application for PEG-INTRON would result in
unified labeling that would be valid in all 15 EU-Member States.
Under the Company's licensing agreement with Schering-Plough, the Company
is entitled to royalties on worldwide sales of PEG-INTRON and milestone
payments. The filing of the BLA by Schering-Plough triggers a $1 million
milestone payment to the Company. The Company will receive an additional $2
million milestone payment upon approval of PEG-INTRON.
Schering-Plough is continuing its development of PEG-INTRON as combination
therapy with REBETOL (ribavirin, USP) for hepatitis C, which is currently in a
multi-national Phase III clinical trial. In addition, PEG-INTRON is in Phase III
clinical trials for two cancer indications, malignant melanoma and chronic
myelogenous leukemia, as well as in early stage trials for various solid tumors
and other forms of leukemia.
INTRON A is a recombinant version of naturally occurring alpha interferon,
which has been shown to exert both antiviral and immunomodulatory effects.
Schering-Plough markets INTRON A, the world's largest-selling alpha interferon,
for 16 major antiviral and anticancer indications worldwide.
