A Phase 4 interventional study of Crizanlizumab in Sickle Cell Disease, sponsored by Novartis Pharmaceuticals. Recruiting at 31 sites in 11 countries. Open to participants aged 6 Months to 100 Years. Per ClinicalTrials.gov, last updated 2026-06-08.
Sponsored by Novartis Pharmaceuticals (part of Novartis) · Phase 4, Interventional, and Treatment
This is a multi-center multi-national rollover study to allow continued access to crizanlizumab for patients with sickle cell disease (SCD) who are on crizanlizumab treatment in a Novartis-sponsored study (parent study) and are benefiting from the treatment as judged by the investigator.
There will be no screening period for this study as patients will transfer directly from parent studies. After providing informed consent, all eligible participants should start Crizanlizumab treatment at the earliest convenience following the treatment schedule of 28 days of the last dose in the parent study. Crizanlizumab will be administered at the same dose/schedule as in the parent study.
Study participants will have a safety follow up visit conducted 105 days after last administration of study treatment. The safety follow up at 105 days is not applicable for those participants who continue to receive Crizanlizumab after end of treatment visit either commercially or through PSDS.
The study is expected to remain open for 10 years from the first Patient's first visit (FPFV) in this clinical study or until study treatment becomes commercially available and is reimbursed in the respective indication or until such time that all enrolled patients no longer need treatment with Crizanlizumab, or a PSDS treatment plan is allowed and approved as per local laws and regulations, whichever comes first

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
