U.S. FDA Approves MydayisTM (mixed salts of a single-entity amphetamine
product) - A New Once-Daily Option for ADHD Symptom Control in Patients 13
Years and Older
Mydayis demonstrated improvements lasting up to 16 hours post-dose, beginning
at 2 or 4 hours post-administration, compared to placebo, in total score on a
skill-adjusted math test that measures attention in ADHD
Lexington, Mass., USA - June 20, 2017 - Shire plc (LSE: SHP, NASDAQ: SHPG)
announced today that the U.S. Food and Drug Administration (FDA) has approved
MYDAYISTM (mixed salts of a single-entity amphetamine product), a once-daily
treatment comprised of three different types of drug-releasing beads for
patients 13 years and older with Attention Deficit Hyperactivity Disorder
(ADHD). Mydayis is not for use in children 12 years and younger. Shire expects
to make Mydayis commercially available in the United States in the third
quarter of 2017.
The U.S. FDA approval of Mydayis is based on results from 16 clinical studies
evaluating Mydayis in more than 1,600 subjects, including adolescents (aged 13
to 17 years) and adults with ADHD. In pivotal, placebo-controlled clinical
studies, Mydayis significantly improved symptoms of ADHD, as measured by the
ADHD-RS-IV and the Permanent Product Measure of Performance (PERMP), in adults
and adolescents. Improvement on the PERMP, an objective, validated,
skill-adjusted math test that measures attention in ADHD patients, reached
statistical significance beginning at 2 or 4 hours post-dose and lasting up to
16 hours post-dose.
"Mydayis is the latest innovation in Shire's 20-year legacy of helping to
support the treatment of ADHD. It's a testament to Shire's commitment to
helping support the evolving needs of appropriate patients with ADHD," said
Flemming Ornskov, M.D., MPH, CEO of Shire. "With this approval, we hope to help
patients who need a once-daily treatment option. Mydayis has shown efficacy
lasting up to 16 hours after taking one capsule, beginning at 2 or 4 hours
post-dose."
Andrew J. Cutler, M.D., Executive Vice President and Chief Medical Officer at
Meridien Research and an investigator in the Mydayis clinical trials said:
"Many of my patients living with ADHD are trying to manage symptoms that impact
them in different settings - often across home life, school or work, and in
social settings. Patients have individual needs and may respond differently to
treatments, so it is important for healthcare professionals to have multiple
options. It's rewarding to work with Shire to provide a new treatment option
that may help appropriate patients with ADHD."
Mydayis, other amphetamine containing medicines, and methylphenidate have a
high chance for abuse and can cause physical and psychological dependence. Your
healthcare provider should check you or your child for signs of abuse and
dependence before and during treatment with Mydayis.
In pivotal Phase 3 clinical studies where efficacy was the primary endpoint, a
morning dose of Mydayis demonstrated superiority to placebo based on the change
from baseline in the ADHD-RS-IV total score for adult and adolescent patients,
respectively. The most common adverse reactions associated with Mydayis
(incidence ?5% and at a rate at least twice placebo) in adults are insomnia,
decreased appetite, decreased weight, dry mouth, increased heart rate, and
anxiety. For pediatric patients (13 years and older), the most common adverse
reactions were insomnia, decreased appetite, decreased weight, irritability,
and nausea.
In Phase 2 studies (two studies in adults and one in adolescents), patients
treated with Mydayis demonstrated improved attention compared to placebo, as
assessed by the total PERMP score, with results reaching statistical
significance beginning at 2 or 4 hours post-dose, and lasting up to 16 hours
post-dose. Across all clinical studies, adverse events were generally mild to
moderate in severity and similar to those observed with other amphetamine
compounds.
ADHD is a neurodevelopmental disorder that manifests as a persistent pattern of
inattention and/or hyperactivity-impulsivity that interferes with functioning
or development. An estimated 4.4% of adults have ADHD in the U.S. When applied
to the full U.S. adult population aged 18 and over, approximately 10.5 million
adults are estimated to have ADHD in the U.S. Approximately 50 to 66% of
children with ADHD may continue to have ADHD symptoms as adults. Medication is
not appropriate for all individuals diagnosed with ADHD.
"Being diagnosed with ADHD as an adult helped me understand my symptoms," said
Gina D'Angelo, an adult patient with ADHD. "Living with my ADHD symptoms is an
ongoing process, and how I navigate my daily responsibilities with ADHD changes
as I learn more about it. It is encouraging to see new options that may help
adults manage their ADHD symptoms."
Mydayis (mixed salts of a single-entity amphetamine product) Important Safety
Information
What is MYDAYISTM?
Mydayis is a prescription medicine used for the treatment of Attention Deficit
Hyperactivity Disorder (ADHD) in patients 13 years and older. Mydayis is not
for use in children 12 years and younger.
IMPORTANT SAFETY INFORMATION
Abuse and dependence. Mydayis, other amphetamine containing medicines, and
methylphenidate have a high chance for abuse and can cause physical and
psychological dependence. Your healthcare provider should check you or your
child for signs of abuse and dependence before and during treatment with
Mydayis.
* Tell your healthcare provider if you or your child have ever abused or been
dependent on alcohol, prescription medicines, or street drugs.
* Your healthcare provider can tell you more about the differences between
physical and psychological dependence and drug addiction.
Who should not take Mydayis?
Do not take Mydayis if you or your child is:
* allergic to amphetamine or any of the ingredients in Mydayis. See the end
of the Medication Guide for a complete list of ingredients in Mydayis.
* taking, or have taken within the past 14 days, a medicine used to treat
depression called a monoamine oxidase inhibitor (MAOI).
Problems that can occur while taking Mydayis. Tell your doctor:
* if you or your child have any heart problems, heart defects, high blood
pressure, or a family history of these problems. This is important because
sudden death has occurred in people with heart problems or defects taking
stimulant medicines, and sudden death, stroke and heart attack have
happened in adults taking stimulant medicines. Your healthcare provider
should check you or your child carefully for heart problems before starting
Mydayis. Since increases in blood pressure and heart rate may occur, your
healthcare provider should regularly check these during treatment. Call
your healthcare provider or go to the nearest hospital emergency room right
away if you or your child has any signs of heart problems such as chest
pain, shortness of breath, or fainting while taking Mydayis.
* if you or your child have mental (psychiatric) problems, or a family
history of suicide, bipolar illness, or depression. This is important
because new or worse behavior and thought problems or new or worse bipolar
illness may occur. New symptoms such as hearing voices, seeing or believing
things that are not real, or new manic symptoms may occur. Call your
healthcare provider right away if you or your child have any new or
worsening mental symptoms or problems during treatment, especially hearing
voices, seeing or believing things that are not real, or new manic
symptoms.
* if your child is having slowing of growth (height and weight); Mydayis may
cause this serious side effect. Your child should have height and weight
checked often while taking Mydayis. Your healthcare provider may stop
treatment if a problem is found during these check-ups.
* if you or your child have circulation problems in fingers and toes
(peripheral vasculopathy, including Raynaud's phenomenon). Fingers or toes
may feel numb, cool, painful, sensitive to temperature and/or change color
from pale, to blue, to red. Tell your healthcare provider if you or your
child have any numbness, pain, skin color change, or sensitivity to
temperature in fingers or toes. Call your healthcare provider if you or
your child have any signs of unexplained wounds appearing on fingers or
toes while taking Mydayis.
* if you have a seizure. Your healthcare provider will stop treatment.
* if you have symptoms of serotonin syndrome such as agitation,
hallucinations, coma, or other changes in mental status; problems
controlling your movements or muscle twitching; fast heartbeat; sweating or
fever; nausea, vomiting or diarrhea; or muscle stiffness or tightness. Call
your healthcare provider or go to the nearest hospital emergency room if
you have these symptoms. Serotonin syndrome may happen when Mydayis is
taken with certain other medicines and may be life-threatening.
* if you or your child are pregnant or plan to become pregnant. It is not
known if Mydayis may harm your unborn baby.
* if you or your child are breastfeeding or plan to breastfeed. You should
not breastfeed while taking Mydayis. Mydayis passes into breast milk.
What are possible side effects of Mydayis?
The most common side effects of Mydayis include:
* trouble sleeping
* decreased appetite
* dry mouth
* increased heart rate
* anxiety
* nausea
* irritability

More About ADHD
Attention Deficit Hyperactivity Disorder (ADHD) impacts people in multiple
settings - even beyond work into daily tasks, at home or in social settings.
The specific etiology of ADHD is unknown. The diagnosis is made utilizing
criteria specified in the Diagnostic and Statistical Manual of Mental
Disorders, Fifth Edition (DSM-5®). Only a trained healthcare professional can
evaluate and diagnose ADHD.
Although there is no cure for ADHD, there are accepted treatments that have
demonstrated improvement in ADHD symptoms. A comprehensive approach is often
advised, which may include a combination of medication, psychotherapy and
educational approaches. Ongoing assessment of ADHD management plans is
recommended.
About the Mydayis Phase 3 Studies
Efficacy of Mydayis in adults (aged 18-55 years) was evaluated in a pivotal
randomized, double-blind, placebo-controlled study of Mydayis 12.5 mg or 37.5
mg in 275 adult patients (Study 1) who met the DSM-5® criteria for ADHD. The
primary endpoint was defined as the change from baseline in the ADHD-RS-IV with
prompts total score compared to placebo. When administered as a daily morning
dose, Mydayis was superior compared to placebo for both the 12.5 mg and 37.5 mg
doses, respectively. In addition, patients treated with either 12.5 mg or 37.5
mg of Mydayis also showed significantly greater improvement compared to placebo
on the Clinical Global Impression of Improvement (CGI-I) score, a key secondary
endpoint.
In a pooled analysis of three Phase 3 clinical trials conducted in 626 adult
ADHD patients, the most commonly reported TEAEs (reported in >5% of
Mydayis-treated patients) were insomnia, decreased appetite, dry mouth,
decreased weight, increased heart rate, and anxiety. Nine percent of
Mydayis-treated patients discontinued due to adverse reactions compared to 2%
of placebo-treated patients. The most frequent adverse reactions leading to
discontinuation (i.e., leading to discontinuation in at least 1% of
Mydayis-treated patients and at a rate at least twice that of placebo) were
insomnia (2%), increased blood pressure (2%), decreased appetite (1%), and
headache (1%).
The efficacy of Mydayis was further assessed in a study that included 157
adolescent (13 to 17 years old) patients (Study 4). This was a randomized,
double-blind, placebo-controlled, dose-optimization study of Mydayis in
patients who met the DSM-IV-TR® criteria for ADHD. Subjects were titrated from
a dose of 12.5 mg/day until an optimal dose was reached (up to a maximum dose
of 25 mg/day). The primary efficacy endpoint was defined as the change from
baseline in the ADHD-RS-IV total score when compared to placebo. The primary
efficacy analysis demonstrated that Mydayis, administered as a daily morning
dose, was superior to placebo with respect to the change from baseline on the
ADHD-RS-IV total score. In addition, Mydayis also showed significantly
greater improvement on the CGI-I score at Week 4, the key secondary endpoint in
this study.
Among adolescent patients in Study 4, the most commonly reported TEAEs
(reported in >5% of Mydayis-treated patients) were decreased appetite, nausea,
insomnia, irritability, and decreased weight. Five percent of Mydayis-treated
patients discontinued due to adverse reactions compared to zero percent of
placebo-treated patients. The most frequent adverse reaction leading to
discontinuation (i.e., leading to discontinuation in at least 1% of
Mydayis-treated patients and at a rate at least twice that of placebo) were
dizziness, depression, upper abdominal pain, and viral infection (all 1%).
Safety and effectiveness of Mydayis have not been established in pediatric
patients ages 12 years and younger.
About the Mydayis Phase 2 Studies
The efficacy of Mydayis in adults (aged 18-55 years) was also evaluated in two
workplace analog studies. These were multi-center, randomized, double-blind,
placebo-controlled, crossover studies in adult patients that evaluated 50 mg
(Study 2, N=86, 42 of whom were treated with 50 mg) or 25 mg (Study 3, N=79, 76
of whom were treated with 25 mg) of Mydayis who met DSM-IV-TR® criteria for
ADHD. Efficacy was assessed by the PERMP total score, calculated as the sum of
the number of math problems attempted plus the number of math problems answered
correctly. The PERMP was administered at 2, 4, 8, 12, 14, and 16 hours
post-dose. Mydayis treatment reached statistical significance compared to
placebo at either 2 hours (Study 2) or 4 hours (Study 3) post-dose and lasting
up to 16 hours post-dose in both studies.
In Study 2, no patients in the Mydayis 50 mg treatment group experienced a
serious TEAE. The most commonly reported TEAEs (reported in >5% of patients) in
the Mydayis 50 mg treatment group included fatigue, insomnia, anorexia,
decreased appetite, headache, dry mouth, hypertension. In Study 3, no patients
experienced a serious TEAE. Two patients reported treatment-emergent adverse
events (TEAEs) that led to study discontinuation. The most commonly reported
TEAEs (reported in >5% of patients) in the Mydayis 25 mg treatment group were
insomnia, decreased appetite, dry mouth, headache, and anorexia.
The efficacy of Mydayis in adolescents was also evaluated in a classroom analog
study (Study 5, 13 to 17 years, N=84 adolescents). The study was a
multi-center, randomized, double-blind, placebo-controlled, crossover study of
Mydayis 12.5 mg or 25 mg who met DSM-IV-TR® criteria for ADHD. Efficacy was
assessed using the PERMP which was administered at 2, 4, 8, 12, 14, and 16
hours post-dose. Mydayis treatment, compared to placebo, resulted in a
statistically significant treatment effect compared with placebo, beginning at
2 hours and continued for up to 16 hours post-dose. In Study 5, TEAEs that were
more common in the Mydayis treatment arms (i.e., frequency >5% in either
Mydayis treatment arm) were upper abdominal pain, dry mouth, nausea, anorexia,
decreased appetite, dizziness, headache, insomnia, irritability, and
dysmenorrhea. There were no reported serious TEAEs and no TEAEs led to study
discontinuation.
