Genzyme Revenues Grow in First-Quarter 2011

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Genzyme Corporation announced today that its first-quarter 2011 revenue grew 7 percent compared with the same period in 2010. Genzyme first-quarter revenue grew to $1.009 billion from $941.9 million in the first quarter of 2010.

Genzyme was acquired in a transaction completed on April 8, 2011, subsequent to the first quarter, and is now a wholly-owned subsidiary of sanofi-aventis (EURONEXT: SAN and NYSE: SNY). Because information concerning Genzyme business prospects and research and development is now found in the public reports of Genzyme’s new parent company sanofi-aventis, this release is limited to historical sales results for the period prior to the change of control. Genzyme sales for this period are not consolidated into the corresponding sanofi-aventis financial statements.

Business Unit Revenue

Personalized Genetic Health

First-quarter revenue from the Personalized Genetic Health business grew 11 percent to $436.9 million from $392.5 million in the first quarter of 2010.

Revenue of Myozyme^® (alglucosidase alfa) / Lumizyme^® (alglucosidase alfa) grew 47 percent in the first quarter to $126.8 million from $86.1 million in the same period last year, driven by U.S. sales of Lumizyme^®, which was approved in May 2010.

First-quarter Cerezyme^® revenue was $183.8 million compared with $179.1 million in the same period in 2010. Sales in the first quarter were impacted by a delay in lot release with a subsequent impact on the timing of shipments, as well as delayed tenders. Patients in Europe and Japan, where there was no inventory available at distributors, missed one infusion during the quarter. Patients in the United States did not miss any infusions; all available inventory was utilized. Overall market share in the first quarter remained stable from the fourth quarter of 2010.

Sales of Fabrazyme^® in the first quarter were $40.9 million compared with $53.2 million in the same period last year, reflecting supply constraints. Production levels continued to be lower than needed to provide patients with full dosing during the quarter. Genzyme expects to be able to provide full dosing to existing patients in the fourth quarter.

Biosurgery

First-quarter revenue from Genzyme’s Biosurgery business increased 12 percent to $153.8 million from $137.4 million in the same period last year. Growth in this segment was driven by sales of Synvisc^® (hylan G-F 20) and Synvisc-One^® (hylan G-F 20), which increased 20 percent to $95.3 million from $79.5 million in the first quarter of 2010. In December, Genzyme launched Synvisc^® in Japan, the largest market in the world for viscosupplements, and first-quarter sales there exceeded expectations.

Hematology and Oncology

First-quarter revenue from Genzyme’s Hematology and Oncology business grew 7 percent to $166.5 million from $156.3 million in the same period in 2010. Results reflect strong U.S. growth of Clolar^® (clofarabine), continued market penetration of Mozobil^® (plerixafor injection), and double-digit growth of Thymoglobulin^® (anti-thymocyte globulin, rabbit), offset by lower sales of the oncology products acquired from Bayer. Genzyme recently received approval of Thymoglobulin^® in Japan for the treatment of acute kidney transplant rejection.

Renal and Endocrinology

First-quarter revenue from the company’s Renal and Endocrinology business was $250.7 million compared with $252.4 million in the same period last year. Results reflect increased sales of Renvela^® (sevelamer carbonate) and Renagel^® (sevelamer hydrochloride) offset by a decrease in sales of Thyrogen^® (thyrotropin alfa for injection) and Hectorol^® (doxercalciferol).

Sales of Renvela^® and Renagel^® grew 14 percent to $187.4 million from $164.6 million in the first quarter of 2010, driven by U.S. growth, the impact of a new tender in Brazil, and the continued successful launch of Renvela^® in the EU.

Sales of Thyrogen^® decreased in the first quarter due to supply shortages caused by manufacturing constraints. Inventory levels of Thyrogen^® are expected to remain low through July, causing temporary shortages in certain countries. The first-quarter decrease in Hectorol^® revenue reflects lower volume due to the launch of a more efficient dosage formulation for dialysis providers, as well as the impact of Medicare’s new bundled payment system for the treatment of end-stage renal disease patients.
