Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Since there was not enough evidence of clinical benefit, this study did not go beyond the first stage in the two stage design. A total of 30 patients (14 in the MPA alone cohort and 16 in the MPA+ ldoCM cohort) were in the study before the study ended.
