FDA ADVISORY
PANEL UNANIMOUSLY RECOMMENDS APPROVAL OF EXTRANEAL(7.5% ICODEXTRIN), BAXTER'S
PERITONEAL DIALYSIS SOLUTION
DEERFIELD, IL., August 9, 2001 - Baxter Healthcare Corporation reported
that the Cardiovascular and Renal Drugs Advisory Committee to the U.S.
Food and Drug Administration (FDA) today unanimously recommended approval
of Extraneal (7.5% icodextrin), a peritoneal dialysis (PD) solution. If
approved by the FDA, Extraneal would be the first solution with a new
osmotic agent introduced for PD patients since 1978 in the United States.
Several members of the advisory
panel requested that Baxter conduct additional analyses of the existing
database in relation to possible blood pressure effects. Further, the
panel recommended that Baxter confer with the FDA to determine if any
post-marketing evaluations may be needed. The FDA seeks expert advice
from advisory committees as part of its review of a New Drug Application
(NDA). However, the final decision regarding the approval of an NDA is
made by the FDA.
Baxter is seeking FDA approval
of its new PD solution, which is uniquely suited to increase ultrafiltration
during the long dwell dialysis exchanges. Dwell is the amount of time
dialysis solution remains in the abdominal cavity during PD therapy, which
is usually performed in the home.
"We are pleased with the
panel's recommendation and intend to work closely with the FDA to discuss
the best course of action for making this product available to PD patients
in the United States," said Marsha Wolfson, M.D., F.A.C.P, vice president,
Global Clinical Affairs, Baxter Healthcare Corporation. "We believe
in the value of this product and its ability to help address an unmet
medical need, particularly due to its positive nine-year commercial track-record
in other countries."
Current dialysis solutions available
in the United States use glucose as the osmotic agent, which acts as the
driving force in the removal of fluids. Because Extraneal uses a novel
osmotic agent, which is a polymer of glucose, it removes fluid more consistently
and in greater amounts over the long dwell as compared to the currently
available 1.5% and 2.5% glucose-based solutions.
Ultrafiltration is the removal
of fluid from the bloodstream during dialysis. During long dwell dialysis
exchanges with currently available solutions, more dialysis fluid may
be absorbed into the blood stream than is removed by ultrafiltration,
which translates into less effective fluid removal. Effective fluid management
is a primary goal of PD according to ultrafiltration management guidelines1
released this year by the International Society of Peritoneal Dialysis,
which recommend, in part, the greater use of dialysis solutions that can
optimize fluid management of the PD patient.
Extraneal solution was granted
Orphan Drug status by the FDA in 1997, and an NDA was filed with the FDA
earlier this year. Extraneal solution is currently approved for marketing
in 31 countries, and more than 8,000 patients are currently using the
solution worldwide. In Europe, more than 7,000 patients, or nearly 30
percent of the total European PD patient population, currently use the
product, which has been available for approximately nine years.
Extraneal solution is contraindicated
in patients with a known allergy to cornstarch or icodextrin or in patients
with glycogen storage disease. In the clinical trials comparing Extraneal
to glucose-based solutions, the most frequent Extraneal treatment-related
adverse event was skin rash. Most cases of rash were mild to moderate
and all cases completely resolved.
Peritoneal Dialysis
Peritoneal dialysis,
which is a form of dialysis performed in a patient's home, uses the peritoneal
membrane as the filter device. To gain access, a catheter is surgically
inserted through the wall of the peritoneal cavity into which the dialysis
solution is infused. Through the process of osmosis, toxins and excess
fluids move across the membrane into the solution. After a predetermined
dwell period, the solution is drained from the cavity through the catheter.
More than 300,000 people in the
United States, or just over one in 1,000 Americans, are being treated
for end-stage renal disease (ESRD), which occurs when the kidneys are
destroyed by disease. The number of people being treated for ESRD in the
United States is growing at about seven percent annually, and as the number
of patients increase, so do the costs for treating the disease. Of the
estimated one million people worldwide suffering from chronic kidney disease
who are treated with some form of dialysis therapy, 10 to 15 percent use
peritoneal dialysis.
Baxter is a leading provider of
renal products and services worldwide. In 1956, the company introduced
the first disposable coil dialyzer, a development that greatly enhanced
the use and application of hemodialysis. Nearly 20 years later, Baxter
was one of the first companies to introduce PD.
Baxter Healthcare Corporation

critical therapies for people with life-threatening conditions. Baxter's
products and services in bioscience (biopharmaceuticals, vaccines, biosurgery
products and transfusion therapies), medication delivery and renal therapy
are used by health-care providers and their patients in more than 100
