About this study
Official title: Study of Crizanlizumab for Prevention of Silent Cerebral Infarcts in SCA Novartis Investigator Initiated Trial: CSEG101AUS12T
In this prospective, single-arm, open-label, imaging and treatment study, the investigator will test the hypothesis that crizanlizumab will prevent the progression of silent cerebral infarcts in patients with sickle cell disease. Study participants will undergo brain MRI before initiation of crizanlizumab and at 6 and 30 months after starting crizanlizumab infusions. The crizanlizumab cohort will be compared to a matched, observational cohort of patients not receiving crizanlizumab.
- Conditions
- Sickle Cell Disease
- Being tested
- Crizanlizumab
- Medical subject headings
- Anemia, Sickle Cell
What participants receive

Questions about this trial
What is this clinical trial studying?
A study testing Crizanlizumab in people with Sickle Cell Disease, run by Andria Ford at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 6 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Andria Ford, MD (314-362-7382, forda@wustl.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
New or enlarged silent cerebral infarcts (time frame: 30 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2023; AzTrials last refreshed its copy on 8 Nov 2026.
