What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Experiencing Adverse Events

    Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

    Measured: 104 weeks

Secondary outcomes (6)

  1. The Efficacy of Belimumab-thrombocytopenia

    Outcome measures scored as complete response (CR), partial (PR), and none (NR) at 24, 52, 104 weeks. For thrombocytopenia, CR defined as a platelet count of ≥150×109/μl,PR as 100-149,and NR as <100.

    Measured: 104 weeks

  2. The Efficacy of Belimumab-CVD

    Outcome measures scored as complete response (CR), partial (PR), and none (NR) at 24, 52, 104 weeks.For CVD,CR defined as the disappearance of cardiac lesions, PR as 50%improvement,and NR as no change.

    Measured: 104 weeks

  3. The Efficacy of Belimumab-renal involvement

    Outcome measures scored as complete response (CR), partial (PR), and none (NR) at 24, 52, 104 weeks. For aPL nephropathy, CR defined as a normal serum creatinine level, inactive urinary sediment, and urinary protein: creatinine 0.5;PR as a serum cr level 15% above baseline, RBCs per high-power field 50% above baseline with no casts, 50%improvement in the urinary prt:cr, and estimated GFR 10%above baseline; and NR as the absence of C/PR.

    Measured: 104 weeks

  4. The Efficacy of Belimumab-cognitive impairment

    Outcome measures scored as complete response (CR), partial (PR), and none (NR) at 24, 52, 104 weeks. For cognitive dysfunction,CR defined as normalization of the cognitive impairment index with 50%improvement,PR as abnormal index with 50%, and NR as no change.

    Measured: 104 weeks

  5. The Efficacy of Belimumab-thrombosis

    Rate of documented thrombotic events

    Measured: 104 weeks

  6. Change in aPL profile

    Change in aPL levels at 24, 52, 104 weeks

    Measured: 104 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Belimumab in people with Antiphospholipid Syndrome, run by University of Turin, Italy at 1 site in Italy.

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 10 inclusion and 24 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 13 Jan 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 Italy. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants Experiencing Adverse Events (time frame: 104 weeks). 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 NCT05020782.

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 13 Jan 2023; AzTrials last refreshed its copy on 6 Nov 2026.
