Participant Flow

A total of 105 participants signed the ICF. 8 participants were screen failures, 3 withdrew their consent and 1 participant could not continue due to internal site issues. Of the 105 participants, 93 received the study drug. 92 completed the overall study. 1 participant did not finish the FUP visit. The study was conducted in 29 sites in 10 countries from 16 August 2023 (First Patient First Visit) to 25 September 2024 (Last Patient Last Visit).
