Acute Lymphoblastic Leukemia Treatment Protocol Moscow-Berlin 2019 Pilot

January 22, 2021 updated by: Federal Research Institute of Pediatric Hematology, Oncology and Immunology

Treatment of Children and Adolescents With Primary B-precursor Acute Lymphoblastic Leukemia With Combination Chemotherapy and Immunotherapy

THE PURPOSE OF THE STUDY is to optimize the therapy of patients with primary B-cell precursor acute lymphoblastic leukemia (BCP-ALL) by including monoclonal bispecific antibodies in post-induction treatment with simultaneous reduction of chemotherapy.

QUESTIONS AND OBJECTIVES OF THE STUDY:

  • to determine the efficacy and feasibility of chemotherapy and immunotherapy combination in comparison with standard PCT in children and adolescents with newly diagnosed BCP-ALL;
  • to determine the safety and toxicity of chemotherapy and immunotherapy combination in comparison with standard PCT in children and adolescents with newly diagnosed BCP-ALL;
  • to determine the possibility of chemotherapy reducing when immunotherapy is included in the treatment regimen without loss of effectiveness;
  • to determine the possibility of reducing the maintenance therapy duration to 1 year when immunotherapy is included in the treatment regimen without loss of effectiveness.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years to 14 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

This study included patients with B-cell precursor ALL (BCP-ALL) diagnosed or confirmed in one of the clinics participating in the study. Also following criteria should be considered at the diagnosis for each case:

  1. Age at diagnosis at 1 to 18 years.
  2. The start of induction therapy within a time interval of study recruitment phase.
  3. The diagnosis of BCP-ALL is to be proved by the morphological, cytochemical, and immunological analysis of tumor cells in bone marrow in the reference laboratories of Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology (D. Rogachev NMRCPHOI).
  4. CD19 expression on tumor cells.
  5. Informed consent of the patient parents (guardians)

Exclusion Criteria:

  1. Any non-compliance with the inclusion criteria.
  2. ALL is a second malignancy.
  3. There is severe concomitant disease, which significantly impedes chemotherapy protocol (such as multiple malformations, heart diseases, metabolic disorders, etc.);
  4. The patient was treated before for a long time with cytotoxic drugs.
  5. Initial CNS (central nervous system) involvement (status CNSII or CNSIII).
  6. Initial leukocyte count ≥100×109/L (except for patients with significant translocations).
  7. Patients not achieved cytological remission after induction

Primary Outcome Measures

Primary Outcome Measures
