About this study

Single-arm, open-label, single center study to assess the efficacy and safety of terbutaline plus danazol in patients with corticosteroid resistant/relapsed ITP.

Read the detailed description

Immune thrombocytopenia (ITP) is a severe bleeding disorder. Approximately 2/3 of patients achieve remission from first-line therapies. However, the underlying mechanism of corticosteroid-resistant or relapsed ITP is not well understood; thus, treatment remains a great challenge. β2-AR agonist terbutaline modulates T cell differentiation and effector cell function.

A single center prospective study was performed in non-splenectomized ITP patients who were either resistant to a standard dose of corticosteroids or had relapsed. Patients were assigned to terbutaline plus danazol group. Platelet count, bleeding and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study, in order to assess the efficacy and safety of terbutaline plus danazol in patients with corticosteroid-resistant/relapsed ITP.

What is being measured

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

  1. Sustained response

    The maintenance of platelet count ≥ 30 x 10^9/L, at least 2-fold increase of the baseline count, the absence of bleeding, and no need for rescue medication at the 6-month follow-up. Interim analysis was scheduled at 50% through recruitment.

    Measured: 6 months

Secondary outcomes (5)
  1. complete remission

    The number of participants (responders) with platelet count>=100x10^9/L (CR) and the absence of bleeding.

    Measured: 6 months

  2. partial remission

    The number of participants (responders) with platelet count >=30x10^9/L and at least a 2-fold increase in the baseline count (PR) without the administration of any other platelet increasing therapy.

    Measured: 6 months

  3. time to response

    Time to response was defined as the time from starting treatment to the time to achieve the response. Interim analysis

    Measured: 6 months

  4. duration of response

    Duration of response was measured from the achievement of response to the loss of response.

    Measured: 6 months

  5. incidence of treatment-emergent adverse events

    Adverse events were scaled according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Terbutaline and Danazol in people with Immune Thrombocytopenia, run by Peking University People's 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 6 inclusion and 9 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 22 Jul 2020. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Contact Xiaohui Zhang, MD (010-88324981, zhangxh100@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sustained response (time frame: 6 months). 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 22 Jul 2020.
