About this study
Official title: Low-dose Rituximab in Combination With Eltrombopag and High-dose Dexamethasone as Frontline Treatment for Immune Thrombocytopenia
The purpose of this study is to determine the response rate and response duration with the combination of low-dose rituximab, eltrombopag and high-dose dexamethasone.
Read the detailed description
Immune thrombocytopenia is an autoimmune disorder characterized by formation of autoantibodies against platelet antigens leading platelet destruction.
Corticosteroids increase the platelet count in about 80 percent of patients. However, many patients have a relapse when the dose of corticosteroid is reduced. Debilitating side effects are common in patients who require long-term corticosteroid therapy to maintain the platelet count. Eltrombopag, it is a small molecule agonist of the c-mpl (TpoR) receptor, which is the physiological target of the hormone thrombopoietin, has been shown to be effectively raise the platelet count in adult patients (aged 18 years and over) who have had their spleen removed or where splenectomy is not an option and have received prior treatment with corticosteroids or immunoglobulins, and these medicines did not work (refractory ITP). There are a few case reports where eltrombopag was an option as first line treatment for IT.
The purpose of this study is to determine the response rate and response duration with the combination of rituximab (100 mg weekly four weeks), eltrombopag (50mg PO once a day, day 1-28) and high-dose dexamethasone (40mg PO days 1-4) in untreated adult patients with <30*109/L platelet count diagnosed with immune thrombocytopenia.
A complete response is defined as an increase in platelet counts to >150×109/L on two consecutive occasions. A clinical response is defined as an increase in the platelet count between >30×109/L on two consecutive measures and no bleeding. Duration of response is considered from the day of the initial administration to the first time of relapse (platelet count <30×109/L) or to time of analysis Patients will be evaluated each week during 4 weeks and then every month for at least 6 months.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Rituximab, Eltrombopag and Dexamethasone in people with Immune Thrombocytopenia, run by Hospital Universitario Dr. Jose E. Gonzalez at 1 site in Mexico.
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 5 inclusion and 7 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 15 Jul 2016. 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 Mexico. 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 David Gómez, MD (+5583486136, dgomezalmaguer@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Clinical Response (time frame: 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02834286, which also lists 4 linked publications.
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 15 Jul 2016.
