What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DupilumabDrug

    Also called Dupixent

    Duplimab was administered according to the guidelines of the atopic dermatitis treatment regimen, which involved the first dose of 600 mg followed by 300 mg every two weeks. Because of comorbidities or the side effects of corticosteroid, some patients used dupilumab in the initial course of treatment, while others added dupilumab when the traditional drugs proved ineffective. The discontinuation was a joint decision between treating dermatologists and patients. Concomitant medicine was decided by clinicians, depending on the assessing of disease status and patients' choices, and reduced according to international guidelines.

What is being measured

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

  1. Proportion of patients reached disease control

    Disease control was defined as the point at which new lesions or pruritic symptoms cease to form and existing lesions start to heal.

    Measured: within 4 weeks

Secondary outcomes (9)
  1. Complete remission rate

    Complete remission is defined as the absence of new or established lesions or pruritus while the patient is receiving minimal therapy or off therapy for at least 2 months.

    Measured: within 64 weeks

  2. Relapse rate

    Relapse was defined as the appearance of three or more new lesions a month or at least one eczematous lesion with a diameter >10cm or urticarial plaque that does not heal within one week, or the extension of established lesions or daily pruritus in a patient who has achieved disease control.

    Measured: within 64 weeks

  3. Adverse events

    Any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure.

    Measured: within 64 weeks

  4. Changes in BPDAI scores

    Disease severity was assessed using the bullous pemphigoid disease area index (BPDAI) score and was classified into mild (BPDAI≤19), moderate (20≤BPDAI≤56), and severe (BPDAI≥57).

    Measured: from 0 to 64 weeks

  5. Changes in itching NRS scores

    Pruritus was evaluated via itching numeric rating scale (NRS), ranging from 0 (no itch) to 10 points (worst imaginable itch).

    Measured: from 0 to 64 weeks

  6. Changes in serum anti-BP180 antibodies

    Measured: from 0 to 64 weeks

  7. Changes in serum anti-BP230 antibodies

    Measured: from 0 to 64 weeks

  8. Changes in serum total IgE

    Measured: from 0 to 64 weeks

  9. Changes in peripheral blood eosinophil count

    Measured: from 0 to 64 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Bullous Pemphigoid, run by Peking University First 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 3 inclusion and 3 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: finished, as of the sponsor's last update on 4 Dec 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 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Proportion of patients reached disease control (time frame: within 4 weeks). 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 4 Dec 2023.
