New Peer-reviewed Publication Offers Guidance for Integrating Gattex® (Teduglutide [rDNA origin]) for Injection into Management



  New Peer-reviewed Publication Offers Guidance for Integrating Gattex®
  (Teduglutide [rDNA origin]) for Injection into Management of Short Bowel
  Syndrome

 First published recommendation for reducing parenteral nutrition/intravenous
                       fluid dependence while on Gattex

Business Wire

BEDMINSTER, N.J. -- January 30, 2013

The Journal of Parenteral and Enteral Nutrition recently published clinical
considerations and best-practice recommendations for introducing Gattex^®
(teduglutide [rDNA origin]) for injection into the management of short bowel
syndrome (SBS). The recommendations conclude that integrating Gattex into a
coordinated approach to treating SBS may result in more success in
rehabilitating the intestine and weaning from parenteral nutrition
(PN)/intravenous (IV) fluids in these patients.

Gattex is indicated for the treatment of adults with SBS who are dependent on
parenteral support. Full prescribing information for Gattex is available at
www.Gattex.com. The complete guidelines can be viewed at the Journal of
Parenteral and Enteral Nutrition website by searching “teduglutide.”

The goal of intestinal rehabilitation is to enhance nutrient processing and
absorptive capacity of the remaining gastrointestinal tract, allowing for
maximum oral intake of nutrients and fluids. Until recently, the approaches
for achieving this goal have been limited to dietary intervention,
antidiarrheal and antisecretory medications, and surgical bowel
reconstruction. The article considers the integration of Gattex, a targeted
agent, in conjunction with best-practice recommendations, including strategies
for PN/IV weaning and the importance of an integrated approach centering on
specialized care.

“Teduglutide achieves intestinal adaptation as evidenced by significant
reductions in PN/IV dependence or even complete weaning of this supportive
care in some patients with short bowel syndrome,” said Douglas L. Seidner, MD,
director of Vanderbilt Center for Human Nutrition at Vanderbilt Medical Center
in Nashville and lead author. “Due to the complexities of short bowel syndrome
and the need for individualized management strategies, patients should be
referred to major centers with experience in short bowel syndrome,
particularly during the early stages of teduglutide treatment.”

Prior to initiating therapy with Gattex, the authors suggest optimizing
fluids, electrolytes, nutrients, and adjunctive medications. They also
recommend establishing baseline parameters for monitoring purposes,
particularly nutrient balance and liver function for those requiring
long-term, home use of parenteral nutrition, or HPN. Pre-planning and
communication between the various healthcare providers and the patient are
strongly recommended to allow for a well-coordinated care plan. Further, the
authors recommend that patients be referred to major centers with experience
in intestinal rehabilitation and that Gattex prescribers adhere to the
warnings and requirements for the specific population of patients described in
the product’s label.

These are the first published recommendations for weaning SBS patients off of
PN/IV while on Gattex. The recommendations detail that the intended approach
to reducing dependence on PN/IV should clearly be determined in the planning
stages, prior to initiating therapy with Gattex, citing patient and caregiver
preferences. It is also recommended that throughout the weaning process, with
or without teduglutide, continued monitoring of key parameters should be
tracked closely to ensure safe withdrawal of PN/IV. In addition, it is
recommended that patients keep a diary to record oral food and fluid intake,
urine output, and stool/stoma characteristics and share it with their
prescribing physician. Further, patients should be educated on signs of fluid
overload that could arise during the weaning process and advised to report
rapid changes in weight and urine output to their prescribing physician.

The guidelines were formed by a panel of experts convened in a roundtable that
was sponsored by NPS Pharmaceuticals. In addition to Dr. Seidner, the panel
consisted of Lauren K. Schwartz, MD, Marion F. Winkler, PhD, RD, LDN, CNSC,
FASPEN, Khursheed Jeejeebhoy, MD, FRCP(C), PhD, Joseph I. Boullata, PharmD,
RPh, BCNSP, Kelly A. Tappenden, PhD, RD, FASPEN, and Joan Bishop of The Oley
Foundation.

About Short Bowel Syndrome

Short bowel syndrome, or SBS, is a serious, complex disorder in which the body
is unable to absorb enough nutrients and fluids through the gastrointestinal
tract to sustain life. SBS patients are commonly infused with parenteral
nutrition and IV fluids, or parenteral support, five to seven nights per week
for up to 10 to 12 hours at a time, and in extreme cases, some patients could
receive parenteral support for 24 hours a day. Long-term use of parenteral
support can be associated with life-threatening complications such as liver
damage, serious bloodstream infections, and blood clots.

SBS typically occurs when a large portion of the intestine has been removed by
surgery caused by disease or injury. In rare cases, it is congenital. Common
symptoms of SBS can include diarrhea, dehydration, malnutrition, and weight
loss, which are closely related to the functional issues of the bowel. During
a typical day, SBS patients will move their bowels up to 10 times, or change
their ostomy bag, which collects their stool output, three to four times. In
extreme cases, patients may move their bowels as many as 25 times each day.

Gattex Clinical Trials

NPS' clinical development program for Gattex is the largest and most
comprehensive conducted in SBS patients to date, consisting of 15 clinical
studies. Across all clinical studies, 566 subjects were exposed to at least
one dose of Gattex, of whom 134 had SBS and were treated with 0.05 mg/kg/day
Gattex. The FDA's approval of Gattex was based on an international, 24-week,
double-blind, placebo-controlled, pivotal Phase 3 trial, known as STEPS. The
primary endpoint of STEPS was defined as a 20 percent or greater PN/IV volume
reduction demonstrated at week 20 and sustained at week 24. The study's
secondary endpoints included reductions in PN/IV volume and additional days
off therapy. Key findings from the STEPS trial include:

  * In an intent-to-treat analysis at weeks 20 and 24, 63 percent of patients
    treated with Gattex achieved at least a 20 percent reduction in weekly
    PN/IV volume when compared to baseline, versus 30 percent for placebo
    (p=0.002).
  * After 24 weeks of treatment, PN volume declined by 32 percent (4.4 L/wk)
    in Gattex-treated patients, versus 21 percent (2.3 L/wk) in the placebo
    group (p<0.001).
  * After 24 weeks of treatment, 54 percent of Gattex-treated patients were
    able to reduce the number of infusion days per week by one or more days,
    compared to 23 percent of those treated with placebo (p=0.005).

The most common adverse reactions (≥10 percent) across all studies with Gattex
are abdominal pain, injection site reactions, nausea, headaches, abdominal
distension, upper respiratory tract infection. In addition, vomiting and fluid
overload were reported in the Phase 3 SBS studies at rates ≥ 10 percent.

About Gattex® (teduglutide [rDNA origin]) for Injection

Gattex^® (teduglutide [rDNA origin]) for injection, for subcutaneous use is a
novel, recombinant analog of human glucagon-like peptide 2, a protein involved
in the rehabilitation of the intestinal lining. Gattex is indicated for the
treatment of adult patients with short bowel syndrome (SBS) who are dependent
on parenteral support. Significant reductions in mean PN/IV infusion volume
from baseline to end of treatment were seen in the Phase 3 studies of Gattex.
In addition, some patients were able to achieve independence from PN/IV
support during these trials. The most common side effects of Gattex include
stomach area (abdomen) pain or swelling, skin reaction where the injection was
given, nausea, headache, cold or flu like symptoms, vomiting, and holding too
much fluid in the body (swelling of face, ankles, hands or feet).

Gattex has received orphan drug designation for the treatment of SBS from the
European Medicines Agency (EMA) and the FDA.

In 2007, NPS granted Takeda GmbH, the rights to develop and commercialize
teduglutide outside the United States, Canada, Mexico and Israel. NPS retains
all rights to teduglutide in North America. The European Commission granted
European market authorization on August 30, 2012 for the medicinal product
teduglutide (trade name in Europe: Revestive®) as a once-daily treatment for
adult patients with SBS.

Important Safety Information (ISI)

Gattex has been associated with serious risks including:

Neoplastic growth. There is a risk for acceleration of neoplastic growth.
Colonoscopy of the entire colon with removal of polyps must be done before
initiating treatment with Gattex and is recommended after 1 year. Subsequent
colonoscopies should be done as needed, but no less frequently than every 5
years. In case of intestinal malignancy discontinue Gattex. The clinical
decision to continue Gattex in patients with active non-gastrointestinal
malignancy should be made based on risk and benefit considerations.

Intestinal obstruction. In patients who develop obstruction, Gattex should be
temporarily discontinued pending further clinical evaluation and management.

Biliary and pancreatic disease. Patients should undergo laboratory assessment
(bilirubin, alkaline phosphatase, lipase, amylase) before starting Gattex.
Subsequent laboratory tests should be done every 6 months. If clinically
meaningful changes are seen, further evaluation is recommended including
imaging, and continued treatment with Gattex should be reassessed.

Fluid overload. There is a potential for fluid overload while on Gattex. If
fluid overload occurs, especially in patients with cardiovascular disease,
parenteral support should be appropriately adjusted, and Gattex treatment
reassessed.

Prescribers should select the appropriate patients to receive Gattex in
accordance with the approved prescribing information, discuss the benefits and
risks of Gattex with patients, and monitor patients as specified in the
approved prescribing information and report adverse events to NPS' Gattex
information line at 1-855-5GATTEX (1-855-542-8839) or event/product complaint
line at 1-855-215-5550.
