PHC IVD and JCR Announces Upgraded Medication
Management App Melon NikkiTM for Pediatric Patients
Undergoing Growth Hormone Therapy

Tokyo and Hyogo, August 8, 2022 - The In Vitro Diagnostics Division of PHC Corporation
(headquarters: Minato-ku, Tokyo, President: Kyoji Morimoto, hereafter PHC IVD), a
provider of medical and diagnostic devices, and JCR Pharmaceuticals Co., Ltd.
(headquarters: Ashiya, Hyogo, Chairman and President: Shin Ashida, hereafter JCR)
announce new features and expanded availability of Melon Nikki TM*1, a dedicated
smartphone app for growth hormone therapy medication management that is used with the
motorized growth hormone delivery device GROWJECTOR® L*2. The renewed app will
now be available on Google Play and App Store*3 from August 2022.


GROWJECTOR® L, manufactured and sold by PHC IVD, and is used exclusively to
administer subcutaneous injections of the recombinant human growth hormone
GROWJECT® (6mg and 12 mg*4), which has been manufactured and sold by JCR since
2017. Melon NikkiTM, co-developed by PHC IVD and JCR, was first launched in October
2020 to support medication adherence when paired with the injector. The dosing history
recorded by the GROWJECTOR® L can be seamlessly sent via Wi-Fi to a smartphone with
the app, allowing easier access to detailed dosing history. Furthermore, Melon NikkiTM can
record the injected area, generate growth curve graphs with a patient’s height and weight
data, and send the PDF data to a PC by e-mail. Also, it is equipped with “fun features*5”
designed to reduce a patient’s injection anxiety and improve their positive attitude toward
injections.


Melon NikkiTM was provided to a clinical study*6, initiated in February 2019, which focused
on the improvement of poor medication adherence. Based on the insights gained from
these clinical studies on the state of treatment and the needs in the market, the two
companies promptly proceeded with development study and are now ready to release an
upgraded product that is iPhone-compatible and supports Bluetooth®-connectivity, aiming
to improve accessibility for patients and healthcare professionals.
With this product upgrade, iPhone users will also be able to download Melon Nikki TM in
addition to Android smartphone users, and the new Bluetooth feature is expected to reduce
the workload in data sharing. Moreover, the new app will help improve the patients’ quality
of life as it creates a new standard for growth hormone therapy contributing to the
advancement of personalized medicine and revolutionizes the diagnosis/treatment for
patients and healthcare professionals as promotion of IoT in healthcare is anticipated in the
industry. With the update of the function of Melon NikkiTM, the function of GROWJECTOR®
L has also been updated. The updated contents of each main specification are as follows.


[Melon NikkiTM]
• Melon NikkiTM is now available on the App Store for iPhone users, in addition to Google
Play for Android users.
• The app now allows parents, relatives, and healthcare professionals to connect to a
patient as “friends” and share information and messages on treatment remotely.
• The app now includes enhanced features to ease patient’s injection anxiety, such as an
avatar that grows with the patient and additional “fun items” using the avatar such as
pets, trips, and events.

available for iPhones users in addition to Android users.

 Application and GROWJECTOR® L Usage


Hiroyuki Tokunaga, Board Member and Director of the In Vitro Diagnostics Business Unit
of PHC Corporation, said, “Since we began developing blood glucose monitoring systems
in 1991, we have developed, manufactured, and sold easy-to-use and highly accurate
testing and analysis equipment to support a range of patient needs. The GROWJECTOR ®
L has been well-received by our customers since its launch in 2017, and we expect that the
enhanced functionality of the product and the Melon NikkiTM app will further reduce the
strain associated with injections for patients and their families and improve the connection
needed for monitoring between healthcare professional and families, leading to more
effective medication treatment. As we integrate our expertise in precision engineering with
digital technology, we will contribute to higher quality medical care by providing healthcare
solutions that help improve the quality of life for patients and respond to pressing diagnosis
and treatment issues.”


Toru Ashida, Vice President and in charge of Corporate Strategy of JCR said, “Since
launching the motorized growth hormone delivery device GROWJECTOR ® in 2006, we
have carried out activities to provide product information as well as conducted research
and development to meet the needs of patients undergoing treatment with recombinant
human growth hormone GROWJECT®. We believe that Melon NikkiTM, released in 2020,
has contributed to supporting self injections in growth hormone therapy and connecting
healthcare professionals with patient’s information. It has become a good example of
healthcare digital transformation in this age of IoT by making growth hormone therapy
more effective. We expect that the upgraded Melon NikkiTM, which is available to iPhone
users and has added new functions, will contribute to even more patients and provide new
value to meet their needs for self injection therapy. We will continue to provide a wide range
of options for the treatment of growth disorders and to contribute to the development of
pediatric care.”
