Fabrazyme, our enzyme replacement therapy for Fabry disease, grew rapidly in 2004 — revenue
more than doubled, and now the majority of treated Fabry patients in Europe use our product. In
2004, Fabrazyme was launched in more than 23 markets, including Japan, and we believe that it will
be a growth driver for Genzyme in 2005. A phase 4 post-marketing study was successfully completed
in 2004. Fabry patients demonstrated a high level of commitment by volunteering for this
placebo-controlled study of their potentially fatal disease despite the availability of commercial
treatment. In early 2005, we filed a supplemental application with the U.S. Food and Drug Administration
(FDA) to obtain changes in the product label that incorporate the findings of this study, and we are
taking similar steps in Europe and other regions.
Aldurazyme, which we developed jointly with BioMarin Pharmaceutical Inc. to treat MPS I, is now available
in more than 30 markets. MPS I attacks young children, and we are engaged in educating pediatricians to
accelerate referrals to geneticists for diagnosis and treatment. To validate our belief that early
treatment can improve outcomes, we are conducting a study of MPS I patients under age 5 that should be
completed in 2005.
Cerezyme, the world's standard of care for Gaucher disease, continued to grow steadily. We focused on
product and service enhancements and on providing greater access, both commercial and humanitarian, to
patients throughout the world.
We are pursuing a global strategy for Myozyme, our enzyme replacement therapy for Pompe disease, which
we are preparing to launch in early 2006.
