About this study

Official title: A Phase I-II Pilot Clinical Trial of Safety and Efficacy of Personalized Targeted Preparative Regimen With Allogeneic TcRαβ/CD19-depleted Hematopoietic Stem Cell Transplantation and Posttransplant Donor T- Cells Infusion in Children With Chemoresistаnt Acute Leukemia.

The purpose of this study is to evaluate the safety and efficiency of personalized targeted therapy in combination with high-dose chemotherapy as part of a preparative regimen before T-depleted allogeneic hematopoietic stem cell transplantation in children with chemoresistant acute leukemias

Read the detailed description

The outcome of hematopoietic stem cell transplantation (HSCT) in a cohort of children with chemorefractory leukemia is poor. The incidence of relapse exceeds 50% and survival varies from 10 to 40%. Additional attempts at remission induction with various combinations of chemotherapy are unlikely to improve the outcome and will contribute to toxicity.

The hypothesis of the study is that personalized targeted therapy combined with high-dose chemotherapy may improve the outcome of allogeneic HSCT in a cohort of pediatric patients with refractory leukemia.

Bcl-2, CD38, CD184 were chosen as potential targets due to frequent expression in pediatric acute leukemias, availability of marketed targeted therapies venetoclax, daratumumab and prelixafor, and expected non-overlapping toxicity profile of these agents and the conditioning regimen.

    Measured: 30 days after HSCT

  2. Overall response rate

    Proportion of patients with hematologic remission at time points

    Measured: 30 days after HSCT

  3. Partial response rate

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Preparative regimen in people with Refractory Acute Myeloid Leukemia and Refractory Acute Lymphoblastic Leukemia, run by Federal Research Institute of Pediatric Hematology, Oncology and Immunology at 1 site in Russia.

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 12 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 20 Nov 2020. 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 Russia. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Larisa Shelikhova (84956647078, larisa.shelikhova@fccho-moscow.ru), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

cumulative incidence of neutrophil and platelets engraftment at day +30 after HSCT (time frame: 30 days after HSCT). The study lists 5 primary outcomes in all. 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 20 Nov 2020.
