Advanced Magnetics Completes Enrollment in Two Phase III Studies of Ferumoxytol as an IV Iron Replacement Therapeutic

CAMBRIDGE, Mass., Sept. 5 (HSMN NewsFeed) -- Advanced Magnetics (Nasdaq: AMAG ) today announced that enrollment has been completed in two of four multi-center Phase III clinical studies of ferumoxytol as an intravenous (IV) iron replacement therapeutic for the treatment of anemia in chronic kidney disease patients, whether or not on dialysis.

One study enrolled 304 non dialysis-dependent chronic kidney disease patients (NDD-CKD) who were randomized to receive either two 510 mg doses of ferumoxytol within one week or 200 mg of oral iron daily for three weeks. The primary endpoint in the study is the mean change in hemoglobin from baseline in the ferumoxytol group compared to that in the oral iron treatment group.

The second study enrolled 750 dialysis-dependent and non-dialysis dependent chronic kidney disease patients in a double-blind, placebo-controlled, crossover safety study.

Additional milestones for the Phase III ferumoxytol iron therapy program include:

* Completion of enrollment in the second multi-center study in NDD-CKD patients, currently planned for the end of calendar 2006.

* Completion of enrollment in the multi-center study in hemodialysis dependent chronic kidney disease patients, currently planned for early 2007.

The next meeting of the Data Monitoring Committee, which provides independent oversight of the ferumoxytol Phase III iron therapy program, is scheduled to occur in October 2006.

The company is working with its Clinical Studies Steering Committee, which has oversight of the publications for the Phase III studies, and its Scientific Advisory Board to determine when data will become available and be presented to the scientific and investment communities.

The company will host a conference call to answer any questions regarding the ferumoxytol Phase III program, including the status of enrollment and availability of data, on Wednesday, September 6, 2006 at 4:15 pm EDT. Participating in the call will be Jerome Goldstein, Chairman and CEO, and Brian Pereira, MD, President.
