- 2-methyltetrahydrofuran (50 mg/day)

On March 25, 2020, ICH had already published the document open for public consultation (Step 2). The proposed values were then adopted as final and included in the final draft of the document (step 4). This will allow for adoption by the regulatory parties of ICH regions, in accordance with the ICH Process (step 5), concluding the review.
