The Japanese regulatory authority has approved the clinical use of anti-amyloid-β (Aβ) immunotherapy for Alzheimer’s disease. This Correspondence highlights the launch of the Japanese Registry for Alzheimer’s Disease-Modifying Therapies, which aims to ensure safety and maximize the optimal risk–benefit balance through integrating a real-world database of adverse events, post-marketing surveillance, APOE genotyping and biomarker research.
Lecanemab, an anti-Aβ-antibody drug for Alzheimer’s disease, received accelerated approval in the USA on 6 January 2023 and was submitted for approval in Japan on 16 January. On 6 July, the US Food and Drug Administration granted full approval for lecanemab. Later that year, the Pharmaceuticals and Medical Devices Agency (PMDA) — the Japanese regulatory authority — approved the clinical use of lecanemab, which was listed in the national health insurance and made available for clinical use on 20 December 2023.
