High-dose Dexamethasone Versus Conventional Dose Prednisone for Initial Treatment of Primary Immune Thrombocytopenia (ITP)

April 18, 2016 updated by: Ming Hou, Shandong University

High-dose Dexamethasone and Conventional Dose Prednisone, for the First-line Treatment of Adults With ITP: a Multicenter, Randomized Controlled, Clinical Trial

The project was undertaking by Qilu Hospital of Shandong University and other 11 well-known hospitals in China. In order to report the efficacy and safety of high-dose dexamethasone compared to conventional dose prednisone for the first-line treatment of adults with primary immune thrombocytopenia(ITP).

Status

Completed

Detailed Description

The investigators are undertaking a parallel group, multicentre, randomised controlled trial of 300 adults with ITP from 11 medical centers in China. Part of the participants are randomly selected to receive high-dose dexamethasone treatment and the other part are selected to receive conventional dose of prednisone treatment. Platelet count, bleeding and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study. In order to report the efficacy and safety of high-dose dexamethasone compared to conventional dose prednisone for the first-line treatment of adults with ITP.

Description

Inclusion Criteria:

  1. Meet the diagnostic criteria for immune thrombocytopenia.
  2. Untreated hospitalized patients, may be male or female, between the ages of 18 ~ 80 years.
  3. To show a platelet count <30 * 10^9/L, and with bleeding manifestations.
  4. Willing and able to sign written informed consent.

Exclusion Criteria:

  1. Received chemotherapy or anticoagulants or other drugs affecting the platelet counts within 3 months before the screening visit.
  2. Received second-line ITP-specific treatments (eg, cyclophosphamide, 6-mercaptopurine, vincristine, vinblastine, etc) within 3 months before the screening visit.
  3. Received high-dose steroids or IVIG in the 3 weeks prior to the start of the study.
  4. Current HIV infection or hepatitis B virus or hepatitis C virus infections.
  5. Severe medical condition (lung, hepatic or renal disorder) other than chronic ITP. Unstable or uncontrolled disease or condition related to or impacting cardiac function (e.g., unstable angina, congestive heart failure, uncontrolled hypertension or cardiac arrhythmia)
  6. Female patients who are nursing or pregnant, who may be pregnant, or who contemplate pregnancy during the study period.
  7. Have a known diagnosis of other autoimmune diseases, established in the medical history and laboratory findings with positive results for the determination of antinuclear antibodies, anti-cardiolipin antibodies, lupus anticoagulant or direct Coombs test.
  8. Patients who are deemed unsuitable for the study by the investigator.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proposed criteria for assessing response to ITP treatments
Time Frame: The time frame is up to 28 days per subject
  1. Complete response (CR): A platelet count ≥ 100 * 10^9/L measured on two occasions > 7 days apart and the absence of bleeding.
  2. Response (R): A platelet count ≥ 30 * 10^9/L and a greater than two fold increase in platelet count from baseline measured on two occasions > 7 days apart and the absence of bleeding.
  3. No response (NR): A platelet count < 30 * 10^9/L or a less than two fold increase in platelet count from baseline or the presence of bleeding. Platelet count must be measured on two occasions more than a day apart.
The time frame is up to 28 days per subject
