About this study

Official title: A Randomized, Controlled Trial Comparing the Safety and Efficacy of Luspatercept Plus Cyclosporine Versus Cyclosporine Alone for the Treatment of Newly Diagnosed Non-transfusion-dependent Non-severe Aplastic Anemia (NSAA)

In a randomized, controlled clinical trial, the efficacy and safety of rodsipil combined with cyclosporine versus cyclosporine alone in the treatment of newly diagnosed non-transfusion-dependent NSAA were compared.

Read the detailed description

Conduct a comparative evaluation of the effectiveness and safety of Luspatercept combined with cyclosporine versus cyclosporine monotherapy in the treatment of newly diagnosed non-transfusion-dependent non-severe aplastic anemia (NSAA). Patients were randomized in a 1:1 ratio and assigned to one of two groups: Group A, Luspatercept combined with cyclosporine: received Luspatercept (1.0 mg/kg, subcutaneous injection every 3 weeks), cyclosporine (3-5mg/kg/day), adjusted based on hematological parameters, for at least 6 months to assess efficacy. Effective patients continued to receive cyclosporine treatment for at least 1.5 years, with a gradual reduction in dosage; Group B, cyclosporine: received 3-5mg/kg/day, adjusted based on hematological parameters, for at least 6 months to assess efficacy, with effective patients continuing to receive cyclosporine treatment for at least 1.5 years, with a gradual reduction in dosage. Hgb below 60g/L was allowed, or in emergency conditions, blood transfusion was allowed. Platelets below 20×10^9/L or with obvious bleeding tendency were allowed to receive platelet transfusion. If neutrophil count was below 1.0×10^9/L, G-CSF was allowed until neutrophil count recovered to above 1.0×10^9/L. Symptoms, treatment-related adverse events, signs, blood transfusion volume, and laboratory tests (including reticulocyte count) were recorded at least every 3 months for the first 3 months, and every 6 months thereafter until 6 months, and bone marrow aspiration, biopsy, and chromosome examination were performed at least every 6 months to observe efficacy and safety.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Luspatercept and cyclosporine in people with Aplastic Anemia, run by Peking Union Medical College Hospital at 1 site in China.

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 9 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: withdrawn, as of the sponsor's last update on 4 Jun 2026. 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 China. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

overall response rate (ORR) (time frame: 6 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06424639, which also lists 14 linked publications.

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 4 Jun 2026.
