One sponsor concentrates Myositis research.
argenx accounts for 2 of 9 trials (22.2%). 8 distinct sponsors appear on at least one study for this condition label.
-
Typical Myositis enrolment sits around 90 participants.
Median target enrolment is 90 among the 9 trials that report a genuine target (sentinel values excluded). 5 of those (55.6%) plan for fewer than 100 participants.
