Sickle Cell Disease study: DISC-3405
Official title A Phase 1b, Open-Label Study of DISC-3405 in Participants With Sickle Cell Disease (SCD)
ClinicalTrials.gov ID: NCT07187973
What this study is testing
What is DISC-3405?
DISC-3405 is an investigational subcutaneous injectable medicine being studied as a potential treatment for sickle cell disease.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether DISC-3405 is safe for people with sickle cell disease. It also looks at how the drug behaves in the body.
- Who it's for
- You may be able to join if you have sickle cell disease and meet the study’s health criteria.
- What's involved
- You will receive different amounts of DISC-3405 at home or in clinic. Doctors will check your health and take blood samples.
- Time commitment
- The study lasts a few weeks and includes several visits for drug doses and blood tests.
- Phase 1: an early, usually small safety study
- Which group you join is decided by chance.
