Trials in Australia

This Australian count is likely to be on the low side. It counts the trials this site files under this condition; the registry’s own search is broader and also returns closely related conditions, some of which have their own page here. If you are searching widely, check the registry as well — every trial below links to its own record.

Trials overseas

155 trials for this disease are open to new participants outside Australia, as ClinicalTrials.gov listed them on 11 October 2026. Voxsanity does not publish a page for any of them; the searches below reach them at the registry.

These overseas counts are likely too high. They come from the registry’s own search, which expands a condition name to related conditions, so some of the trials counted are for a different disease in the same family.

About Immune Thrombocytopenia

The text below is reproduced exactly as its source published it. It has not been edited, shortened or rewritten.

Immune thrombocytopenia is a disorder characterized by a blood abnormality called thrombocytopenia, which is a shortage of blood cells called platelets that are needed for normal blood clotting. Affected individuals can develop red or purple spots on the skin caused by bleeding just under the skin's surface. Small spots of bleeding under the skin are called purpura and larger spots are called ecchymoses. People with immune thrombocytopenia can have significant bleeding episodes, such as nose bleeds (epistaxis) or bleeding in the moist lining (mucosae) of the mouth. In severe cases, individuals may have gastrointestinal bleeding or blood in the urine or stool, or heavy and prolonged menstrual bleeding (menorrhagia). In very rare instances, bleeding inside the skull (intracranial hemorrhage) can occur, which can be life-threatening. A greater reduction in platelet numbers is often associated with more frequent bleeding episodes and an increased risk of severe bleeding. While immune thrombocytopenia can be diagnosed at any age, there are two periods when the condition is most likely to develop: early childhood and late adulthood. In children, the reduction in platelets is often sudden, but platelet levels usually return to normal levels within weeks to months. Immune thrombocytopenia in children is often preceded by a minor infection, such as an upper respiratory infection, but the relationship between the infection and immune thrombocytopenia is not clear. In adults, the development of immune thrombocytopenia is usually gradual and the condition tends to persist throughout life.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
