About this study

Official title: A Phase I/II Study of Immunotherapy With Humanized Anti-CD20 Antibody, IMMU-106 (hA20), in Adult Patients With Chronic Immune Thrombocytopenic Purpura

This trial will study different dose levels of hA20 (IMMU-106) to see if they are safe and effective for treating ITP.

Read the detailed description

The goal of current treatment guidelines for most patients with chronic adult ITP is to maintain platelet levels above 30 x 109/L. The conventional first-line therapy is corticosteroids with or without intravenous immunoglobulins, but many patients relapse when steroids are tapered. Standard therapy then is splenectomy, but patients with refractory ITP who do not respond require further therapy. Unfortunately, immunosuppressive agents or other available treatments typically produce only short-term responses. Because of the lack of medical options after first-line therapy, the target population for this first study of anti-CD20 immunotherapy with hA20 are adult patients with chronic ITP who failed at least one standard ITP therapy (i.e., received at least one standard ITP therapy and now present with platelet levels below 30 x 109/L).

In autoimmune disease, rituximab as well as other anti-CD20 antibodies currently being considered for commercialization have focused on a different dosing schedule in rheumatoid arthritis, and use fixed dosages rather than variable doses based on body surface area. In addition, recent studies of these newer anti-CD20 antibodies in rheumatoid arthritis have reported that lower doses indeed appear effective when administered twice, 2 weeks apart. Based upon these considerations, patients in this study will receive hA20 twice, 2 weeks apart, and administered at one of 3 dose levels.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing veltuzumab in people with Purpura, Thrombocytopenic, Idiopathic and Autoimmune Thrombocytopenic Purpura, run by Gilead Sciences at 8 sites in United States.

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 7 inclusion and 1 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: stopped early, as of the sponsor's last update on 16 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

The study was stopped early. Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary - Safety (time frame: 1 year). The study lists 2 primary outcomes in all. 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 NCT00547066, which also lists 2 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 16 Aug 2021.
