A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Age ≥16 years; subjects age 16 or 17 years must be documented Tanner Stage 5 (see Appendix 3).
- Documented diagnosis of sickle cell disease (SCD) (HbSS, HbSC [combined heterozygosity for hemoglobins S and C], HbS/β0-thalassemia, HbS/β+-thalassemia, or other sickle cell syndrome variants).
- At least 2 sickle cell pain crises (SCPCs) (defined in Section 8.5.2.1) and no more than 10 SCPCs in the 12 months prior to providing informed assent/consent.
- Hemoglobin ≥5.5 and ≤10.5 g/dL. Hemoglobin concentration must be based on an average of at least 2 Hb concentration measurements (separated by ≥7 days) collected during the Screening Period.
- If taking hydroxyurea, the hydroxyurea dose must be stable for at least 90 days prior to randomization. Discontinuation of hydroxyurea requires a 90-day washout prior to informed assent/consent.
- Women of childbearing potential (WOCBP) must be abstinent of sexual activities that may induce pregnancy as part of their usual lifestyle or agree to use 2 forms of contraception, one of which must be considered highly effective, from the time of providing informed assent/consent, throughout the study, and for 28 days after the last dose of study drug. The second form of contraception can include an acceptable barrier method (see Appendix 2).
You likely can't join if
- Pregnant or breastfeeding.
- Other protocol defined exclusion criteria may apply.
- Receiving regularly scheduled transfusions.
- Hospitalized for an SCPC and/or other vaso-occlusive event within 14 days prior to providing informed assent/consent or during the Screening Period. A hospitalization is defined as an in-patient admission to a hospital that may or may not be preceded by an emergency room or out patient clinic visit. A visit to an emergency room that does not result in an in-patient admission does not meet the definition of hospitalization
- Currently receiving treatment for SCD (eg, voxelotor, crizanlizumab, L glutamine), with the exception of hydroxyurea. The last dose of voxelotor, crizanlizumab, and L-glutamine must have been administered at least 90 days before starting study drug.
- Currently receiving treatment with hematopoietic stimulating agents; the last dose must have been administered at least 90 days before starting study drug.
