Study summary

The project was undertaking by Qilu Hospital of Shandong University and other 18 well-known hospitals in China. In order to report the efficacy and safety of decitabine combining with dexamethasone for the treatment of adults with immune thrombocytopenia (ITP), compared to dexamethasone alone .

Read the detailed description

The investigators anticipate to undertaking a parallel group, multicentre, randomised controlled trial of 200 ITP adult patients from 19 medical centers in China. One part of the participants are randomly selected to receive dexamethasone (given 40mg/d for 4 consecutive days as a cycle , If platelet count remained below 30 × 109/L or there were bleeding symptoms by day 10, an additional cycle of dexamethasone was given) combining with decitabine (given intravenously at a dose of 3.5mg/m2/d for 4 consecutive days as a cycle and repeated every 2 weeks for 3 cycles), the others are selected to receive dexamethasone therapy(given 40mg/d for 4 consecutive days as a cycle, If platelet count remained below 30 × 109/L or there were bleeding symptoms by day 10, an additional cycle of dexamethasone was given). 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 the combination therapy compared to dexemathasone alone therapy for the treatment of adults with ITP.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Meet the diagnostic criteria for immune thrombocytopenia.
  2. within 3 months fromdiagnosis,untreated patients, may be male or female, between the ages of 18 \~ 80 years.
  3. To show a count \< 30×10\^9/L, and with bleeding manifestations.
  4. (ECOG)performance status ≤ 2.

Exclusion criteria

Exclusion Criteria:

  1. Received chemotherapy or anticoagulants or other drugs affecting the counts within 3 months before the screening visit.
  2. Received high-dose or intravenous immunoglobulin transfusion(IVIG) in the 3 weeks prior to the start of the study.
  3. Current infection or virus or virus infections.
  4. Severe medical condition (lung, hepatic or renal disorder) other than 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)
  5. Female patients who are nursing or pregnant, who may be pregnant, or who contemplate pregnancy during the study period.
  6. Have a known diagnosis of other 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.
  7. Patients who are deemed unsuitable for the study by the investigator.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Evaluation of platelet response(continuous response rate)

    Complete Response:a sustained (≥ 3 months) platelet count ≥100×10\^9/L;response: a sustained (≥ 3 months) platelet count ≥ 30×10\^9/L without recurrence of thrombocytopenia;No response (NR): 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.

    Time frame: up to 1 year per subject

Secondary outcomes

  1. therapy associated adverse events

Start is estimated for Sep 2018; primary completion for Dec 2020, 27 months later.

Of 57 phase 3 interventional studies under Purpura, Thrombocytopenic, Idiopathic, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 49. This study's planned 27 months is close to that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 15, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
