Mapping lifecycle management activities for blockbuster drugs in Japan based on drug approvals and patent term extensions

Strategic balance of drug lifecycle management options differs between domestic and foreign companies in Japan

INTRODUCTION

Drug approvals and patent protections are critical in drug lifecycle management (LCM) in order to maximize drug discovery investment returns.

AREA COVERED

We analyzed drug LCM activities implemented by 10 top companies in Japan, focusing on drug approvals and patent term extensions.

EXPERT OPINION

Foreign companies acquired numerous drug approvals primarily for new molecular entities (NMEs), while Japanese companies mainly obtained approvals for improved drugs including new indications, and intensively extended patent terms. Furthermore, we discovered three factors likely responsible for differences in drug LCM strategies of Japanese and foreign companies: research and development capacities for drugs, drug lags of foreign-origin NMEs, and cooperation between Research and Development Departments and Intellectual Property Departments.
