About this study

Official title: IIT2017-05-MERIN-BLINHMCT: Blinatumomab Plus HLA-Mismatched Cellular Therapy (HMCT) for Relapsed/Refractory CD19+ ALL

Single center Phase 1 dose escalation trial of the combination of standard-of-care blinatumomab plus Haplo-Mismatched Cellular Therapy (HMCT). HMCT refers to the infusion of donor peripheral blood mononuclear cells collected via pheresis from a haploidentical family member - the procedure is analogous to giving a donor lymphocyte infusion outside of the setting of an allogeneic stem cell transplant; also known as 'microtransplantation'. The HMCT is an unselected mix of lymphocytes and leukocytes, but the product dose escalation will be done based on the T cell content.

Ten recipients are planned. Each subject will be administered one infusion of HMCT during the first cycle of blinatumomab and two infusions during cycle two of blinatumomab; the CD3+ cell dose of the HMCT infusion is governed by dose escalation / de-escalation following a Bayesian method.

Read the detailed description

This single center, phase 1 study will examine the safety, side effects, and effectiveness of combining the investigational use of Haplo-Mismatched Cellular Therapy (HMCT) in combination with blinatumomab. Investigators plan to give HMCT starting on day 15, after the initial CRS caused by blinatumomab has resolved. The investigational treatment will start with 1% of the typical HMCT dose (10e6 CD3+ cells/kg) and will employ a modified dose escalation design as an additional safety measure. The primary end points will be DLT of the combination of blinatumomab and HMCT.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Blinatumomab and Haplo-Mismatched Cell Therapy (HMCT) in people with B-Cell Acute Lymphoblastic Leukaemia and ALL, Adult, run by Cedars-Sinai Medical Center at 1 site 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 13 inclusion and 13 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: finished, as of the sponsor's last update on 5 Feb 2025. 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 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 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.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Incidence of DLTs (time frame: up to 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 Feb 2025.
