Clinical trials

This study is a treatment protocol with blinatumomab for infants under 1 year old who are diagnosed with acute lymphoblastic leukemia with a specific unfavorable genetic alteration. The purpose of the study is to improve the outcome of this disease in infants.

This is a non-randomized, open label phase Ib/II dose-escalation and expansion study designed to define the recommended dose of anti-GD2-800CW in pediatric neuroblastoma patients. The aim of this imaging study is to determine a safe and effective dose of anti-GD2-800CW for intra-operative detection of neuroblastoma using NIR fluorescence.

The iLTB is a proof-of-concept initiative for children with r/r hematological malignancies, in which available treatment options will be prioritized by actionable events in a harmonized and uniform setting across Europe by a team of biologists, bio-statisticians, bio-informaticians, disease experts, geneticists, flow-experts, clinical trial physicians and also the treating physician. The iLTB will discuss molecular (genetic lesions), immunophenotypic/surface antigen markers information and, if available, drug response profiles to prioritize these events taking into account the treatment history and treatment intention (bridging to hematopoietic stem cell transplanation/CAR-T or palliative) of each patient followed by a registry to monitor how often iLTB advice has been followed, which other therapy was chosen (off-label, compassionate use) and what the patient outcome is at an aggregated level. As such the iLTB is non-interventional as it mainly provides advice and registers data on patients discussed in the iLTB.

This is an open-label, phase I-II dose-escalation and expansion study designed to define the recommended dose of brigatinib as monotherapy in pediatric and young adult patients with ALK+ ALCL, IMT or other solid tumors and to evaluate the pharmacokinetics (PK), (long-term) safety, and efficacy of brigatinib in these children.

Treatment with intensive chemotherapy in AML results in approximately 70% survival in newly diagnosed patients. Prognosis at relapse is worse and is in the 30-40% range. Relapse treatment generally consists of one course of fludarabine, cytarabine and liposomal daunorubicin (FLAG-DNX), followed by a fludarabine and cytarabine course, and subsequent stem-cell transplantation. Cytarabine has been used in combination with fludarabine and cladribine, with the aim to induce synergism by increasing Ara-CTP (active cytotoxic metabolite from ara-C) accumulation, which can be seen as a surrogate marker for cytarabine induced cell-kill. Synergy with cytarabine can also be achieved with clofarabine, which is a potent inhibitor of ribonucleotide reductase, leading to a depletion of normal deoxynucleotides and subsequently to increased Ara-CTP levels. The phase IB trial ITCC020/I-BFM 2009-02 recently reported that clofarabine, replacing fludarabine in the standardly used fludarabine, cytarabine and liposomal daunorubicin (FLAG-DNX) combination regimen, showed high response rates (Overall Response Rate - ORR 68% and 80% at the recommended phase 2 dose - RP2D) in patients with refractory/relapsed AML, and was generally tolerable, with infectious complications as the main side-effect due to the immunosuppressive properties of clofarabine. Currently DNX is unavailable, which urges the need to develop other treatment blocks. The liposomal formulation of Vyxeos®/CPX-351 may be a suitable replacement for DNX, considering the long-term side effect of cardiotoxicity due to anthracyclines which is of primary importance in younger heavily pre-treated patients. The hypothesis is that due to the liposomal formulation there is less penetrance in the cardiac muscle and hence less cardiac damage. The results in pediatric and young adult patients with relapsed/refractory AML in a COG study using Vyxeos®/CPX-351 at a RP2D of 135 U/m2 (AAML1421) showed encouraging ORR, with 70% of patients reaching CR/CRi as best response after single agent-treatment with Vyxeos®/CPX-351. Preclinical data have also demonstrated an increased Ara-CTP accumulation and cytotoxicity in cell lines, and were confirmed by tests in ex-vivo blasts from a cohort of AML patients (n=5), when cells were exposed to Vyxeos®/CPX-351 after 4 hours of incubation with fludarabine. In this study Vyxeos®/CPX-351 was evaluated in combination with clofarabine with the aim to establish the RP2D of this combination.

The CHIP-AML22 Master protocol has the overall aim of increasing the cure rate in newly diagnosed pediatric de novo AML patients, while avoiding unnecessary toxicity. The linked Quizartinib trial (CHIP-AML22/Quizartinib) is a phase II, single arm, open label, study on the safety, efficacy, pharmacokinetics and pharmacodynamics of quizartinib in combination with chemotherapy and as single-agent after high dose therapy in newly diagnosed pediatric AML patients with a FLT3-ITD mutation and NPM1 wild-type.

The goal of this clinical trial is to to assess the dose level of dinutuximab Beta (DB) when combined with 2 different induction chemotherapy regimens (named GPOH or rapid COJEC) in newly diagnosed high-risk neuroblastoma patients. The main question is: • to assess the safety and tolerability and identifying the recommended phase II dose and/or the maximum tolerable dose of dinutiximab Beta when combined with 2 standard induction chemotherapy regimens Participants will receive: * GPOH + dinutuximab beta infusion duration = 10 mg/m2 × 5 days (50 mg/m2/course) in 21-day treatment intervals. * Rapid COJEC + dinutuximab beta infusion duration = 10 mg/m2 × 3 days (30 mg/m2/course) in 10-day treatment intervals.

PACMAN is a phase I/II single arm, open-label, multi-center study evaluating the safety of human CD19 CAR-T (huCAR19) produced locally using the Miltenyi Prodigy in children, adolescents and young adults with relapsed/refractory CD19+ hematological malignancies for whom no standard of care treatment is available.
