Outline of Final Research Achievements

The market exclusivity period of a new drug should be optimized for the entire pharmaceutical industry, since it is necessary to recoup the huge investment in new drug development, while it also makes the timing of the launch of relatively inexpensive generics and biosimilars. This study analyzes the institutional factors that affect the market exclusivity period, with a particular focus on biopharmaceuticals such as antibody drugs, and, in light of recent developments, identifies issues in the current system that will likely affect the market exclusivity period for new drugs in the future.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、我が国の医薬品産業において、新薬開発のインセンティブを失わずに、ジェネリック・バイオシミラー市場を拡大していくための適正な新薬市場独占期間の設定に資するものである。新薬市場独占期間に関する制度的要因は多岐にわたるため、それらを複合的、包括的に分析し、将来的に各ステークホルダーに与える影響を予測することは社会的意義がある。
