A Study of Immune Suppression Treatment for People With Sickle Cell Disease or β-Thalassemia Who Are Going to Receive an Allogeneic Hematopoietic Cell Transplantation (HCT)
NCT05736419 · View on ClinicalTrials.gov ↗
Study Summary
Hematopoietic Cell Transplantation/HCT involves receiving healthy blood-forming cells (stem cells) from a donor to replace the diseased or damaged cells in participants' bone marrow. The researchers think giving participants treatment with fludarabine and dexamethasone, drugs that lower the activity of the body's immune system (immune suppression), before standard conditioning therapy and HCT may help prevent serious side effects, including graft failure and GvHD. In this study, depending on how participants' body responds to the fludarabine and dexamethasone, the study doctor may decide participants should receive another drug, called cyclophosphamide, instead of fludarabine. In addition, depending on the results of participants' routine blood tests, participants may receive the drugs bortezomib and rituximab, which also help with immune suppression.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05736419
The ClinicalTrials.gov registry entry for NCT05736419 describes a study currently listed as recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 24 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Memorial Sloan Kettering Cancer Center, which has 2,280 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Sickle Cell Disease appearing as the primary indexed condition, and to 5 interventions — of which Cyclophosphamide is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05736419 reports 6 study locations spanning 2 distinct geographic areas — top geographies include New Jersey, New York. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
