HT-1 is a rare genetic disorder that may result in liver, renal and
neurological complications. The Orfadin Ambassadors are patients and
caregivers who can share their experiences living with or managing HT-1,
provide guidance in navigating diet and lifestyle challenges, and answer
questions about their experiences with Orfadin® (nitisinone). Orfadin is
the first medicine approved for the treatment of HT-1; it must be used
in combination with dietary restriction of tyrosine and phenylalanine;
please see important safety information below.

"When the doctor told us our daughter Claire had HT-1, we were so scared
and had no idea what to expect," said Shannon, a mother and Orfadin
Ambassador. Over time, Shannon has learned ways to educate her local
school and community about Claire's needs, and how to plan ahead to
manage Claire's HT-1. "We keep learning new ways to take care of Claire.
Having a supportive community that understands what you are going
through is invaluable. I hope that by sharing my story, I can make the
journey a little easier for other families living with this condition."

"Just because you have HT-1 doesn't mean you can't do most of the things
you want to do. But you have to take care of yourself, follow your diet,
and take your medicine as prescribed by your physician," said Colin, a
22-year-old skier and videographer, who is also an Orfadin Ambassador.

The Orfadin Ambassador program is a phone-based, peer-to-peer program
that allows adults with HT-1 or caregivers of HT-1 patients to talk to
another patient or caregiver who has experience with HT-1 and Orfadin.
The goal of the program is to provide members of the HT-1 community with
support and help navigating living with or caring for a person with
HT-1. Orfadin ambassadors are paired with a Health Educator on each
call; neither may provide medical advice. The Orfadin Ambassador program
is supported by Sobi. More information is available at,
by calling 844-581-5872, or through

"Sobi is proud to have reliably provided Orfadin to HT-1 patients for
almost 25 years, and we are committed to supporting the HT-1 community,"
said Rami Levin, President of Sobi in North America. "In addition to
providing innovative treatments for HT-1, we listen and strive to
address the needs of patients and caregivers, which is why we developed
the Orfadin Ambassador program."

Indication and Usage
Orfadin is a synthetic reversible
inhibitor of 4-hydroxyphenylpyruvate dioxygenase indicated for use as an
adjunct to dietary restriction of tyrosine and phenylalanine in the
treatment of hereditary tyrosinemia type 1 (HT-1).

Important Safety Information

  • Tyrosine levels can increase in the blood if you do not restrict
    tyrosine and phenylalanine in your diet while taking Orfadin. Too much
    tyrosine in the blood can cause serious eye problems or other
  • Do not adjust your Orfadin dosage in order to lower the tyrosine
    levels in the blood.
  • A reduction in the number of white cells and platelets in the blood
    have been observed during treatment with Orfadin. Your platelet and
    white blood cell counts should be monitored regularly during Orfadin
  • The most common adverse reactions to taking Orfadin are liver cancer,
    liver failure, low platelets or white cells in the blood, and
    complaints related to the eyes, including conjunctivitis, corneal
    opacity, inflammation of the cornea, and extreme sensitivity to light.
  • Tell your physician promptly if you have unexplained eye symptoms,
    rash, jaundice (yellowing of the skin or whites of the eyes) or
    excessive bleeding.
  • Use Orfadin during pregnancy only if the potential benefit justifies
    the potential risk to the fetus.
  • Nursing women should discontinue either Orfadin or breast-feeding
    based on the recommendation of your healthcare professional.

About hereditary tyrosinemia (HT-1)
Hereditary tyrosinemia
type 1 (HT-1) is an extremely rare but treatable hereditary disorder.
When a child has HT-1, their body lacks the enzymes needed to break down
the amino acid tyrosine, which comes from food. High levels of tyrosine
can build up in the blood and form toxic substances in the liver,
kidneys and central nervous system, which can cause liver, renal and
neurological complications. Approximately 1,000 persons worldwide are
identified as living with HT-1 today.

About Orfadin®
Orfadin® (nitisinone) blocks the breakdown of
tyrosine, thereby reducing the amount of toxic tyrosine by-products in
the body. Patients must maintain a special diet in combination with
Orfadin treatment as tyrosine is not adequately broken down. Before the
introduction of Orfadin, fewer than one-third of infants diagnosed with
HT-1 before two months of age lived past their second birthday. Today,
many HT-1 patients have entered adolescence or adulthood. Orfadin is a
proprietary product and is developed and made available globally by
Sobi. For full European prescribing information, please visit the EMA
website. For full US prescribing information, please see
Full Canadian prescribing information can be found on the Sobi
North America website

Orfadin is the first nitisinone product approved in the U.S. and Europe.
The U.S. approval of the once-daily formulation was based on the results
of a clinical study in 16 HT-1 patients, comparing a 4-week once-daily
and 4-week twice daily dosing regimen. The study showed comparable
blood-levels of nitisinone for these two regimens. The original approval
in the U.S. in 2002 was based on an open-label study of 207 HT-1
patients, in which patients younger than 2 months of age who were
treated with dietary restrictions and Orfadin experienced 2- and 4-year
survival probabilities of 88% and 88%, respectively. Data from
historical controls showed that patients treated with dietary
restriction alone had 2- and 4-year survival probabilities of 29% and
29%, respectively. For patients presenting between 2 and 6 months of age
who were treated with dietary restrictions and Orfadin, 2- and 4-year
survival probabilities were 94% and 94%, respectively. Data for
historical controls showed that patients treated with dietary
restriction alone had 2- and 4-year survival probabilities of 74% and
60%, respectively. The most common adverse reactions (incidence >2%)
seen with Orfadin use are hepatic neoplasm, liver failure,
thrombocytopenia, leucopenia, visual system complaints including
conjunctivitis, corneal opacity, keratitis, and photophobia. Please see
important safety information below.
