List of antipsychotics under development in 2024【Revised 2024.1.26】

この記事は約10分で読めます。

Introduction

I’ll do as much research as I can about the antipsychotics in development in the list below, and I’ll write articles about them one by one. I would be happy if you think that innovative drugs will come in the future.

This article lists antipsychotics. In addition, I added drugs for negative and cognitive symptoms to the list.

I’ll investigate the study results, mechanism of action, efficacy, side effects, which stage of study (phase) it is in, and which company is developing it.

It seems that the clinical trial process in Japan takes about 0.5-1 years for Phase I, about 2 years for Phase II, and about 2-3 years for Phase III.

A drug is released about 1 year after the application, and it takes about 8 years in total from the start of the clinical trial.

Concerning drugs already released overseas, once a clinical trial for a drug begins in Japan, it takes at least 5 or 6 years before it is released.

However, for example, Pyridoxamine has been in clinical trial for about 10 years and is still in phase II. Some drugs may be substantially delayed or even withdrawn from trials.
