Pre-assignment details
A total of 549 subjects gave informed consent in SP0994 and were included in the Enrolled Set, 548 subjects received at least 1 dose of study medication and were included in the Safety Set (SS). Participant Flow refers to the Safety Population including all enrolled subjects who received at least 1 dose of study medication in the current study.
