WOODCLIFF LAKE, N.J., March 26, 2013 /PRNewswire/ --Eisai Inc. announced
today that the U.S. Food and Drug Administration (FDA) has approved ACIPHEX^®
Sprinkle™ Delayed-Release Capsules 5mg and 10mg for the treatment of
Gastroesophageal Reflux Disease (GERD) in children 1 to 11 years of age for up
to 12 weeks.

"We are proud to offer a new treatment option for young children who suffer
from GERD," said Lonnel Coats, president and CEO of Eisai Inc. "Eisai is
committed to keeping the medical needs of patients and their families at the
forefront of all that we do, as part of our human health care (hhc) corporate
mission."

The approval of ACIPHEX Sprinkle is based on the results of a clinical trial
of pediatric patients 1 to 11 years of age. The clinical trial was a
multicenter, double-blind, parallel-group study conducted in 127 pediatric
patients with endoscopically-proven GERD that consisted of a 12-week treatment
and a 24-week extension period of two dose levels of rabeprazole. Overall, 81
percent of patients achieved healing during the 12-week treatment period and
90 percent retained healing during the ensuing 24-week extension period. The
absence of a placebo group does not allow assessment of sustained efficacy
through 36 weeks.

In the 12-week treatment period, the most commonly reported treatment-emergent
adverse events (greater than or equal to 5% of subjects) were cough (14%),
vomiting (14%), abdominal pain (12%), diarrhea (11%), pyrexia (10%), headache
(9%), upper respiratory tract infection (8%), oropharyngeal pain (6%), and
nasopharyngitis (5%).

In the 24-week extension period, the most commonly reported treatment emergent
adverse events (greater than or equal to 5% of subjects) were upper
respiratory tract infection (13%), vomiting (11%), abdominal pain (8%),
diarrhea (6%), pyrexia (5%), nasopharyngitis (5%), pharyngitis streptococcal
(5%), and sinusitis (5%).

Indication for ACIPHEX Sprinkle
ACIPHEX Sprinkle is indicated for the treatment of GERD in children 1 to 11
years of age for up to 12 weeks.

Important Safety Information about ACIPHEX Sprinkle:

  oSymptom relief does not rule out other serious stomach conditions.
  oSerious allergic reactions may occur. Tell your doctor if you have a rash,

    period of time may have an increased risk of fractures of the hip, wrist,

    least 3 months. Tell your doctor right away if you experience any of these
    symptoms: seizures, dizziness, abnormal or fast heartbeat, jitteriness,
    jerking movements or shaking (tremors), muscle weakness, spasms of the
    hands and feet, cramps or muscle aches, or spasm of the voice box.

About Gastroesophageal Reflux Disease (GERD)
Gastroesophageal reflux disease (GERD) is a chronic digestive disease that
occurs when stomach acid or, occasionally, bile flows back (refluxes) into
your food pipe (esophagus). The backwash of acid irritates the lining of your
esophagus and causes GERD signs and symptoms.

Signs and symptoms of GERD include acid reflux and heartburn. Both are common
digestive conditions that many people experience from time to time. When these
signs and symptoms occur at least twice each week or interfere with your daily
life, doctors call this GERD.
