About this study
Official title: International Proof of Concept Therapeutic Stratification Trial of Molecular Anomalies in Relapsed or Refractory HEMatological Malignancies in Children, Subprotocol A: Decitabine / Venetoclax and Navitoclax in Pediatric Patients With Relapsed or Refractory Hematological Malignancies
HEM-iSMART is a master protocol which investigates multiple investigational medicinal products in children, adolescents and young adults (AYA) with relapsed/refractory (R/R) ALL and LBL. Sub-protocol A is a phase I/II trial evaluating the safety and efficacy of Decitabine / Venetoclax and Navitoclax in children and AYA with R/R pediatric ALL/LBL
Read the detailed description
HEM-iSMART is a master protocol with sub-protocols. The overarching objective is that introducing targeted therapy using a biomarker driven approach for treatment stratification may improve the outcome of children with R/R acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) It is characterized by a shared framework that allows for the investigation of multiple IMPs and generate pivotal safety and efficacy evidence within the sub-protocols to establish and define the benefits and risks of new treatments for children with R/R leukemia.
Sub-protocol A within HEM-iSMART, is a phase I/II, multicenter, international, open-label clinical trial designed to evaluate the safety, tolerability, pharmacokinetics (PK) and efficacy of decitabine, venetoclax and navitoclax in children, adolescents and young with R/R ALL and LBL. The epigenetic approach may improve outcome for patients whose tumor lack molecular alterations.

What is being measured
The primary outcome is the main question the study is designed to answer.
Phase I: Maximum tolerated dose (MTD) / Recommended phase 2 dose (RP2D)
Defined as the highest dose level tested at which 0/6 or 1/6 patients experiences dose limiting toxicities (DLT) during course 1 with at least 2 patients experiencing DLT at the next higher dose.
Measured: 3 years
Phase II: Best overall response rate (ORR)
For patients with leukemia: CR and MRD response after 1 cycle of treatment. This includes determination of CR, CRp, CRi and minimal residual disease (MRD) negativity rate in patients suffering from overt morphological relapse of T-ALL at time of enrolment (morphological disease (M2/M3)), and the MRD negativity rate in those that entered with high-MRD levels but in morphological CR. These results will together be presented as a composite endpoint Overall Response rate (ORR). MRD negativity will be defined as ≤1x10-4 as generated by multi-parameter flow cytometry.
For patients with lymphoma: Response in LBL patients is defined as CR, PR, minor response (MR) as defined in International pediatric NHL response criteria. In case of bone-marrow involvement MRD will be taken into account.
Measured: 6 years
Secondary outcomes (7)
Overall survival (OS)
Defined as time from C1D1 until death of any cause.
Measured: 7 years
Event-free survival (EFS)
Defined as time from C1D1 to the first event (subsequent relapse after CR (including molecular reappearance), death of any cause, failure to achieve remission (CR, CRp or CRi), or secondary malignancy).
Measured: 7 years
Cumulative incidence of relapse (CIR)
Estimate of the risk, that a patient will develop a relapse over a specified period of time.
Measured: 7 years
Number of patients proceeding to hematopoietic stem cell transplantation (HSCT) after the experimental therapy.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Decitabine, Venetoclax and Navitoclax in people with Acute Lymphoblastic Leukemia, in Relapse and Lymphoblastic Lymphoma (Precursor B-Lymphoblastic Lymphoma/Leukaemia) Recurrent, run by Princess Maxima Center for Pediatric Oncology at 1 site in Netherlands.
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 25 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: withdrawn, as of the sponsor's last update on 21 Jun 2024. 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 Netherlands. 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 withdrawn before enrolling participants, so there are no results.
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?
Phase I: Maximum tolerated dose (MTD) / Recommended phase 2 dose (RP2D) (time frame: 3 years). 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?
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 21 Jun 2024.
