I am a dedicated professional with extensive experience in safety management and post-marketing surveillance (PMS) in the pharmaceutical industry. After joining SANWA KAGAKU KENKYUSHO CO., LTD., I focused on risk management for diabetes medications and treatments for dialysis complications. My work included PMS literature development and cardiovascular event evaluations, contributing significantly to drug development.
At CureApp, Inc, a company specializing in software as medical devices, I served as the Safety Management Officer. I successfully established the safety management system and operational processes for Japan's first therapeutic app. My involvement in risk management for various therapeutic applications, including those for hypertension, allowed me to engage deeply with the core aspects of product development.
Currently, I am the Head of Quality Assurance at JMDC, Inc, where I oversee GxP compliance and reliability assurance. I am actively involved in building a new PMS framework that combines e-source data with additional collected data, as well as managing certification acquisition and maintenance.
