**Shire plc** (LON: SHP, NASDAQ: SHPG), the leading global biotechnology company
focused on rare diseases, announced today that additional data from the Phase 3 
HELP (Hereditary Angioedema Long-term Prophylaxis) Study™, evaluating the efficacy
and safety of subcutaneously administered lanadelumab in HAE, will be presented 
at the American College of Allergy, Asthma & Immunology (ACAAI) 2018 Annual Scientific
Meeting. HAE is a rare, genetic and potentially life-threatening disorder that can
result in recurrent attacks of oedema (swelling) in various parts of the body.

Data showed that patients treated with lanadelumab 300 mg every two weeks experienced
significantly fewer HAE attacks, were less likely to have moderate or severe attacks
or use rescue medication (primary and secondary endpoints), and were more likely
to be HAE attack-free than those treated with placebo. These results were noted 
during the entire 26-week treatment period and, according to a post hoc sensitivity
analysis, were greatest for patients during the 16-week steady state period (days
70-182).

> **Andreas Busch, Ph.D., Executive Vice President, Head of Research and Development
> at Shire said,** “For those living with this chronic and unpredictable disease,
> it is important that they can reduce the frequency of their HAE attacks. Additional
> analysis of the HELP Study continues to support the use of lanadelumab as a preventive
> subcutaneous treatment option for HAE in appropriate patients 12 years of age 
> and older.”

Interim results from the HELP Study open-label extension found treatment with lanadelumab
was generally well-tolerated and consistent with the previously observed safety 
profile. At the time of interim analysis, patients had been exposed to lanadelumab
for a mean (SD) of 8.21 (2.17) months and continued to experience a reduction in
HAE attacks.

> “The data we have seen from the HELP open-label extension are very promising and
> we look forward to receiving the final results,” **said Dr. Busch.**

**About the HELP Study™**
 The HELP Study™ was a multicentre, randomised, double-
blind, placebo-controlled parallel group trial that evaluated the efficacy and safety
of subcutaneously administered lanadelumab versus placebo over 26 weeks in 125 patients
12 years of age or older with HAE.

The primary endpoint of the HELP Study™ was the number of investigator-confirmed
HAE attacks over the entire 26-week study duration. Lanadelumab demonstrated that
subcutaneous injections every two or four weeks reduced the mean monthly number 
of attacks across all three lanadelumab treatment arms studied: 300 mg every two
weeks, 300 mg every four weeks, and 150 mg of lanadelumab every four weeks.

No serious Treatment Emerging Adverse Events (TEAEs) or deaths were reported. The
most common TEAE was HAE attack. The most commonly reported adverse events, excluding
events related to HAE attacks, were injection site pain (42.9%), followed by upper
respiratory infection (23.8%), headache (20.2%) and injection site erythema (9.5%).
The majority of TEAEs were mild to moderate in severity. TEAEs resulted in discontinuation
for 1 patient from the 300 mg every four weeks lanadelumab arm (ALT/AST elevation)
and 2 from the placebo arm (tension headache, HAE attack).

**About the HELP Study™ Extension**
 The long-term safety and efficacy of lanadelumab
for the prevention of HAE attacks continues to be evaluated in a 132-week open-label
extension study.

In the extension study, 212 adolescent and adult patients received at least one 
dose of lanadelumab. Of these, 109 patients are rollover participants from the HELP
Study™ and 103 are new (non-rollover) participants who had a confirmed diagnosis
of HAE and a historical baseline attack rate of >1 attack per 12 weeks.

**About Lanadelumab**
 Lanadelumab is a fully human monoclonal antibody that specifically
binds and decreases plasma kallikrein activity. Lanadelumab is produced in Chinese
Hamster Ovary (CHO) cells by recombinant DNA technology. Lanadelumab is formulated
for subcutaneous administration and has a half-life of approximately two weeks in
patients with HAE.

Lanadelumab was approved under the brand name TAKHZYRO™ in the U.S. on 23 August
2018 and Canada on 19 September 2018 to prevent attacks of HAE in patients 12 and
older, and additional regulatory submissions are ongoing worldwide. For full U.S.

**About Hereditary Angioedema**
 HAE is a rare, genetic disorder estimated to affect
about 1 in 10,000 to 1 in 50,000 people worldwide. The condition results in recurring
attacks of oedema (swelling) in various parts of the body that can be debilitating
and painful. Laryngeal attacks that obstruct the airways are potentially life-threatening
due to the risk of asphyxiation. Aside from the burden of the disease itself, patients
can suffer anxiety, fatigue and depression between attacks.

**Shire’s Commitment to Hereditary Angioedema**
 Shire is a dedicated, long-term
partner to the HAE community with nearly a decade of experience supporting patients.
We believe people living with HAE deserve a right-fit approach to treatment and 
are committed to serial innovation. Our existing portfolio of products includes 
a number of therapy options to help meet the needs of those living with the disease.
Beyond our focus on developing novel treatments, we provide specialised services
and support offerings tailored to the HAE community.
