St. Jude Medical, FDA and Top Pediatric Cardiology Experts Announce New Clinical Trial to Treat Congenital Heart Defects

Within a new U.S. clinical trial, St. Jude Medical is helping
physicians evaluate minimally invasive device as alternative to open
heart surgery for babies—including premature newborns

ST. PAUL, Minn.–(BUSINESS WIRE)–$STJ #AdvaMed2016–St. Jude Medical, Inc. (NYSE:STJ), a global medical device company,
today announced the launch of the ADO II AS (AMPLATZER™
Duct Occluder
II Additional
Sizes) pediatric clinical trial. The
U.S. IDE clinical trial will evaluate the safety and effectiveness of
the St.
Jude Medical™ AMPLATZER™ Duct Occluder II AS (ADO II AS), a
first-of-its-kind device specifically designed for closure of the small
patent ductus arteriosus (PDA). St. Jude Medical now has two ongoing
U.S. cardiology IDE clinical trials for pediatric patients. In 2014, the
company launched the HALO trial to evaluate the safety and effectiveness
of the SJM™ Masters HP Series 15mm mechanical heart valve, the smallest
pediatric mechanical heart valve in the world.

Congenital heart disease (CHD) is the most common cause of major
congenital anomalies, representing a major global health challenge.
Every year CHD affects 1.35 million babies worldwide. Nearly 25 percent
of babies with a congenital heart defect require surgery during their
first year.

“The patients who would be eligible for this study are the tiniest and
most fragile we care for—severely premature newborns who in many cases
are critically ill from the presence of a patent ductus arteriosus
(PDA),” said national investigator Dr. Evan Zahn, director of the Guerin
Family Congenital Heart Program in the Cedars-Sinai Heart Institute and
Department of Pediatrics at Cedars‐Sinai Medical Center in Los Angeles.
“The AMPLATZER Duct Occluder II AS will provide an experimental option
to surgery. Surgery has many risks in this delicate population and a
minimally invasive approach is desperately needed for this fairly common
and often quiet serious problem.”

Despite the large number of babies worldwide born with CHD, many
children are treated with adult-sized devices, which may not be optimal
for their tiny hearts. St. Jude Medical and the U.S. Food & Drug
Administration (FDA) have long recognized the need for solutions and
educational resources to support pediatric patients.

In 2007, the U.S. Congress passed the Pediatric Medical Device Safety
and Improvement Act to prompt development of medical devices designed
and engineered specifically for the pediatric patient population. In
collaboration with the FDA and top congenital heart disease experts, St.
Jude Medical is addressing the unique challenges of developing,
evaluating and bringing to market devices intended for pediatric use.

With more than 17 years of demonstrated clinical experience, the
AMPLATZER™ family of occluders is the most studied transcatheter cardiac
defect closure devices in the marketplace today. Adding to this body of
clinical data, specifically for pediatrics, the ADO II AS IDE trial will
enroll a maximum of 50 patients at up to 10 sites nationwide. Patients
in the trial will fall within two study groups:

• A minimum of 15 patients less than or equal to 2 KG (approx. 4.4
  pounds)
• A minimum of 25 patients greater than 2 KG

Designed to treat PDA—one of the most common of all congenital heart
anomalies—the ADO II AS device conforms to the smallest ducts while
achieving complete closure from a pulmonary or aortic artery approach.
Data collected during the ADO II AS trial across all trial sites will be
used to support a pre-market approval submission of the device to FDA.
The ADO II AS device is currently approved for use in more than 50
countries outside the United States.

“St. Jude Medical is continuing to build its legacy of innovation in the
field of pediatric cardiology, and working to break the barriers to
developing new CHD treatments so more children’s health conditions can
be properly addressed,” said Dr. Srijoy Mahapatra, vice president of
clinical, medical and scientific affairs at St. Jude Medical. “We are
passionate about helping kids thrive, along with creating medical
solutions that save and improve their lives.”

Building on the Momentum of the HALO IDE Clinical Trial
The
other pediatric clinical trial from St. Jude Medical is evaluating the
safety and efficacy of the SJM Masters HP Series 15mm mechanical heart
valve, the smallest pediatric mechanical heart valve in the world. In
the United States alone, more than 35,000
babies are born each year with congenital heart defects, some of
which will impact valve function to the point they cannot be repaired
and will require surgical
valve replacement. The HALO
IDE trial is enrolling pediatric patients in need of mitral valve
replacement who cannot be implanted with the current range of approved
valves without additional risks and who have no alternative approved
treatment options.

The HALO IDE trial stems from a new approach to the design, evaluation
and regulatory approval of pediatric heart valves that emerged from a
FDA-led workshop in 2010 organized in response to the pressing need to
develop products for this patient population. During the 2nd
Annual Pediatric Surgical Innovation Symposium, former FDA
Commissioner Dr. Margaret A. Hamburg cited the St. Jude Medical
pediatric heart valve as an example of what collaboration can achieve
when industry, FDA staff, clinicians and academics come together to
support pediatric medical device development.
