Participant has completed the originating inclacumab study within 30 calendar days of the Day 1 Visit. Participants who discontinued study drug in the originating study due to a non-study drug-related adverse event (AE), but who remained on study, may be eligible for treatment in this study provided the AE does not pose a risk for treatment with inclacumab. 3. Female participants of childbearing potential are required to have a negative urine pregnancy test prior to dosing on Day 1. Note: Female participants who become of childbearing potential during the study must be willing to have a negative urine pregnancy test to remain in the study. 4.

If sexually active, male participants must use barrier methods of contraception until 165 days after the last dose of study drug. 5. Participant has provided written informed consent/assent.
