Shire launches MyPKFit for Advate® [antihemophilic factor (recombinant)] in the U.S.

First and only FDA-cleared PK dosing software now available to help healthcare professionals create personalized treatment regimens for patients 16 and older with hemophilia A1

CAMBRIDGE, MA, USA I March 5, 2018 I Shire plc (LSE: SHP, NASDAQ: SHPG), the global biotechnology leader in rare diseases, today announced the U.S. availability of myPKFiT for ADVATE [Antihemophilic Factor (Recombinant)], a free web-based, Rx software that is the first and only pharmacokinetic (PK) dosing software cleared by the U.S. Food and Drug Administration (FDA) for use with hemophilia A patients 16 and older weighing at least 45 kilograms and treated with ADVATE.1 The software generates a patient's estimated individual PK profile, which aids healthcare professionals in personalizing a patient's prophylaxis ADVATE dose and schedule.1

"A version of myPKFiT has already been widely adopted in Europe since 2014, and we've seen how important it has been in helping physicians develop personalized dosing regimens tailored to the specific needs of their patients," said Andreas Busch, Global Head of Research and Development, Shire. "As part of our commitment to precision medicine, we are pleased to bring this innovative application to physicians and patients in the United States."

The myPKFiT for ADVATE software offers an innovative approach to estimating a patient's PK curve, a key measure for assessing drug exposure over time.1,2 With myPKFiT for ADVATE, healthcare professionals can now estimate a full PK curve with as few as two measurable blood samples, compared to the 9 to 11 recommended by the International Society on Thrombosis and Haemostasis (ISTH) guidelines.1,3

"We understand that people with hemophilia have their own treatment goals, needs and challenges that require a customized approach to care," said Michael Tarantino, M.D., Medical Director and President, The Bleeding and Clotting Disorders Institute. "The myPKFiT software enables healthcare professionals to gain an even clearer picture of their patients' treatment needs to develop an ADVATE prophylaxis dose and schedule that's truly tailored to each individual patient."

Hemophilia A, the most common type of hemophilia, is a rare bleeding disorder that causes longer-than-normal bleeding due to a lack of clotting factor VIII (FVIII) in the blood.4 The severity of hemophilia A is determined by the amount of factor in the blood, with more severity associated with lower amounts of factor.5 More than half of patients with hemophilia A have the severe form of the condition.5 Hemophilia primarily affects males, with an incidence of one in 5,000 male births in the United States. 6

myPKFiT for ADVATE software is Rx Only. For safe and proper use of the myPKFiT for ADVATE software, please refer to the complete instructions for use in the User Manual.

myPKFiT for ADVATE Indications for Use8

The myPKFiT software is intended for use by licensed healthcare professionals (HCPs) who are familiar with hemophilia care. The myPKFiT software can be used to generate ADVATE dosage amount and frequency recommendations for routine prophylaxis for an individual patient 16 years of age and older and body weight of 45 kg or greater, using that patient's age and body weight information and local laboratory FVIII one-stage clotting activity measurements of sparse samples collected from that patient.

A minimum of two sparse sampling points are required at the recommended 3-4 hours (± 30 minutes) and at 24-32 hours (±1 hour) post-infusion.

HCPs will also be able to evaluate various prophylaxis dose regimens tailored to an individual patient's needs and treatment plan.

The software output may be used to guide decisions on appropriate ADVATE dose and infusion intervals to maintain FVIII activity levels at or above a user specified minimum FVIII activity level between 1% to 3% above natural baseline for an individual patient in accordance with the FDA-approved dosing recommendations provided in the ADVATE Prescribing Information (PI).

myPKFiT should only be used to evaluate prophylactic dosing regimens for hemophilia A patients treated with ADVATE, as per the ADVATE Prescribing Information (PI).

myPKFiT for ADVATE is not indicated for the treatment of von Willebrand disease. myPKFiT for ADVATE should not be used for patients who have developed neutralizing antibody (inhibitor) to FVIII products.

ADVATE is a full-length (derived from the complete FVIII gene) recombinant FVIII product that is processed without any blood-based additives.9

ADVATE is currently approved in 69 countries worldwide, including the United States, Canada, 28 countries in the European Union, Algeria, Argentina, Australia, Brazil, Brunei, Chile, China, Colombia, Ecuador, Hong Kong, Iceland, India, Iraq, Israel, Japan, Kuwait, Macau, Malaysia, Mexico, Morocco, New Zealand, Norway, Panama, Puerto Rico, Qatar, Russia, Saudi Arabia, Serbia, Singapore, South Korea, Suriname, Switzerland, Taiwan, Tunisia, Turkey, Ukraine, Uruguay, and Venezuela.
