Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with sickle cell disease who are currently enrolled in a Novartis-sponsored study and are benefiting from crizanlizumab treatment.
✕Probably not a fit
Patients who have permanently discontinued crizanlizumab treatment in the parent study will not benefit from this rollover study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This multi-center, multinational rollover study allows patients with sickle cell disease who have previously participated in a Novartis-sponsored crizanlizumab study to continue receiving the treatment. Eligible participants will transfer directly from their parent study without a screening period, starting crizanlizumab treatment as per the established schedule. The study aims to monitor the safety and efficacy of crizanlizumab over an extended period, with follow-up visits scheduled after treatment. The study is expected to last up to 10 years or until the treatment becomes commercially available.
Why it matters
Potential benefit: If successful, this study could provide ongoing access to crizanlizumab for patients benefiting from its treatment for sickle cell disease.
How similar studies have gone: Other studies involving crizanlizumab have shown promising results, indicating a potential for continued success with this rollover approach.
