Tokyo and Hyogo, September 15, 2020 - PHC Corporation (headquarters: Minato-ku, Tokyo, President: Kyoji Morimoto, hereafter PHC) and JCR Pharmaceuticals Co., Ltd. (headquarters: Ashiya, Hyogo, Chairman and President: Shin Ashida, hereafter JCR) announce a dedicated smartphone application for the motorized growth hormone delivery device GROWJECTOR® L*1 that the two companies have jointly developed. This application will be provided to the Tokyo Medical and Dental University (Bunkyo-ku, Tokyo) and other medical institutions for clinical research starting September 2020.

The application will be provided for clinical research in the following area:
“Exploratory study on the effect on medication adherence*2 for short-stature children when using new growth hormone liquid formulation aimed to reduce injection irritation” (Project Leader: Dr. Kenichi Kashimada of Tokyo Medical and Dental University Graduate School of Medical and Dental Sciences, Department of Pediatrics and Developmental Biology).

GROWJECTOR® L is a motorized drug delivery device manufactured and sold by PHC, that is used exclusively for the recombinant human growth hormone GROWJECT® subcutaneous 6mg and 12mg*3 treatment that is manufactured and sold by JCR. The device records patient injections (dosing history), which are stored in the device memory. Using the dedicated application, the dosing history stored in GROWJECTOR® L can be wirelessly transmitted to a smartphone, allowing patients to more easily check the details of a specific injection, as well as review detailed dosing history including the time and number of injections.

Previously, gathering accurate data had been difficult, as it was dependent on patient memory, as well as recorded information. The planned clinical research will use the application to accurately collect basic data related to the detailed dosing history (adherence rate), and is expected to provide useful knowledge on the correlation between irritation during injection and maintaining on treatment, as well as improving medication adherence in growth hormone therapy.

The application has already been provided to the clinical research program “Effectiveness of smartphone-based mobile application on medication adherence in patients receiving growth hormone therapy - An exploratory observation study (UMIN000035997)”*4 (Project Leader: Dr. Tatsuhiko Urakami of Nihon University Hospital) that is aiming to gain information for practical use. Data collection for this research program has completed, and the application is planned for Google Play release in Japan this October.
