About this study

Official title: An Exploratory, Open-label, Multicenter Study to Evaluate the Safety and Efficacy of ATIR, Donor T-lymphocytes Depleted ex Vivo of Host Alloreactive T-cells, in Patients With a Hematologic Malignancy, Who Received a CD34-selected Hematopoietic Stem Cell Transplantation From a Haploidentical Donor

The purpose of this study is to determine whether ATIR is safe and effective in reducing transplant-related mortality and improving overall survival, when infused in patients with a hematologic malignancy following a T-cell depleted stem cell graft from a related haploidentical donor.

Read the detailed description

Study CR-AIR-007 is an exploratory, open-label, multicenter study. After signing informed consent, patients will receive a hematopoietic stem cell transplantation (HSCT) from a related, haploidentical donor, followed by infusion with ATIR between 28 and 32 days after the HSCT (or later if required by the patient's medical condition). Patients will receive ATIR as a single infusion at a dose of 2x10E6 viable T-cells/kg. All patients treated with ATIR will be followed up until 12 months after the HSCT. Assessments will be performed at weekly visits from the day of ATIR infusion until 8 weeks after ATIR infusion, at monthly visits from 3 until 6 months after the HSCT, every 2 months from 6 until 12 months after the HSCT, and every 6 months from 12 until 24 months after the HSCT.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Transplant-related Mortality (TRM)

    TRM is defined as death due to causes other than disease relapse or progression, or other causes which are unrelated to the transplantation procedure (e.g. accident, suicide). The TRM rate is displayed as a function of time using the Kaplan-Meier method. The TRM rate at 6 months post HSCT is estimated from this analysis.

    Measured: At 6 months post HSCT

Secondary outcomes (6)
  1. Immune Reconstitution

    Immunophenotyping on peripheral blood samples by means of flow cytometry assessment of immune subsets was done if the absolute lymphocyte count was higher than 0.1×10E9/l

    Measured: Up to 24 months post HSCT

  2. Relapse-related Mortality (RRM)

    Defined as death due to disease relapse or disease progression. The Kaplan-Meier analysis resulted in estimates and 95% confidence intervals (CI)s.

    Measured: 6, 12 and 24 months post HSCT

  3. Overall Survival (OS)

    Defined as the time from HSCT until death from any cause. The Kaplan-Meier analysis resulted in estimates and 95% CIs.

    Measured: 6, 12 and 24 months post HSCT

  4. Progression-free Survival (PFS)

    Defined as the time from HSCT until relapse, disease progression, or death, whichever occurs first. The Kaplan-Meier analysis resulted in estimates and 95% CIs.

    Measured: 6, 12 and 24 months post HSCT

  5. Number of Participants With Viral, Fungal, and Bacterial Infections.

    Measured: Up to 24 months post HSCT

  6. Number of Participants With Graft Versus Host Disease (GVHD)

    Measured: Up to 24 months post HSCT

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ATIR in people with Acute Myeloid Leukemia and Acute Lymphoblastic Leukemia, run by Kiadis Pharma at 8 sites in 4 countries.

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 2 inclusion and 22 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 12 Apr 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 Belgium, Canada, Germany, United Kingdom. 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?

Yes. Results are posted in the registry (first posted 12 Jan 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Transplant-related Mortality (TRM) (time frame: At 6 months post HSCT). 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 12 Apr 2021.
