Inclusion criteria

Inclusion criteria: Inclusion Criteria Participants who meet all the following criteria will be eligible for study enrollment: 1. Male or female participant with SCD who participated and received study drug in a GBT-Sponsored inclacumab clinical study. 2. Participant has completed the originating inclacumab study within 30 days prior to 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 (UTP) prior to dosing on Day 1. Note: Female participants who become childbearing during the study must be willing to have a negative UPT to remain in the study. 4. If sexually active, female participants of childbearing potential must use highly effective methods of contraception until 165 days after the last dose of study drug. 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. For underage (i.e., = 18 years of age) participants, both the consent of the participant’s legal representative or legal guardian and the participant’s assent (where applicable) must be obtained based on local requirement.
