Study Description

Relapse of AML is driven by chemotherapy resistant stem cells. One mechanism of chemotherapeutic resistance in AML is the overexpression of the protein B-cell lymphoma 2 (BCL-2), an anti-apoptotic protein which sequesters intracellular activators of apoptosis. Venetoclax is a selective, potent, orally bioavailable, small molecule inhibitor of B-cell lymphoma (BCL)-2 that restores programmed cell death in cancer cells.

This is a trial for children, adolescents and young adults with 2nd relapsed AML or 1st relapsed AML unable to receive additional anthracycline.

This is randomized trial of venetoclax in combination with intensive chemotherapy (fludarabine/cytarabine/gemtuzumab ozogamicin) for the first two cycles that would inform and evaluate if this agent is an effective option for this population to improve its poor prognosis. Participants can receive up to two cycles of induction chemotherapy before hematopoietic stem cell transplantation (HSCT). Participants benefiting from treatment and who are not able to proceed to HSCT have the possibility to continue to receive azacitidine in monotherapy (Arm A, control arm) or in combination with venetoclax (Arm B, experimental arm).

Study Description

A Phase II pilot trial will estimate survival after a non-TBI based conditioning regimen in patients diagnosed with B-acute lymphoblastic leukemia (ALL) who are pre-allogeneic hematopoietic cell transplantation (HCT) next-generation-sequence (NGS) minimal residual disease (MRD) negative.

The relationship of NGS-MRD status to survival in children, adolescents, and young adults with B-ALL undergoing any approach to allogeneic HCT will be explored in a larger cohort (treatment [phase II] and observational arms of the study).

The primary objective is to estimate 2-year event free survival (EFS) in pre-HCT NGS-MRD negative patients with B-ALL undergoing a non-TBI based conditioning regimen through a multi-center prospective trial. The accrual period is 3 years.

Patients that are NGS-MRD negative with B-ALL may be eligible for the Treatment Arm, which is myeloablative non-TBI conditioning with busulfan, fludarabine, and thiotepa followed -matched related, unrelated, and umbilical cord blood transplants. Patients that are NGS-MRD positive will be followed on the observational arm for outcome.

Study sampling will include NGS-MRD bone marrow (BM) aspirate and peripheral blood (PB) samples collected [same day when possible] pre-HCT (within 4 weeks), and post-HCT on days 42 ± 14, 100 ± 20, and 365 ± 60; PB samples only will also be collected day 180± 60 and 270± 60; day +30, day +100, and 1-year post-HCT. NGS-MRD peripheral blood sample only at 6 months and 9 months post-HCT; (Blast specimen at time of diagnosis or relapse is required for NGS-MRD testing).

Study Description

 This study is eligible for STEP-1 funding. Find more information here. 

Both Australia (Zero Childhood Cancer) and Canada (PROFYLE) have developed precision oncology programs for the pediatric population through which samples from childhood/adolescent cancers undergo in depth genetic profiling. OPTIMISE is a companion platform trial, which will link patients to novel targeted agents based on their tumor profile. The trial will have multiple basket arms based on the most common genetically altered pathways the investigators have identified in these childhood cancers. Each arm of the trial will be histopathology agnostic and test a rational, novel combination therapy, to maximise potential clinical benefit.

The information below is for Treatment Arm A which will be combining, for the first time, paxalisib with conventional chemotherapy in paediatric patients with high-risk malignancies.

Inclusion Criteria

• Patients must be diagnosed with a solid tumor, CNS tumor or lymphoma that has progressed despite standard therapy, or for which no effective standard therapy exists.
• Age <21 years at inclusion; patients 21 years and older may be included after approval by the Study Chair if they have a pediatric type recurrent/refractory malignancy.
• Patients must be enrolled on a precision medicine study (i.e. PROFYLE, ZERO or equivalent as agreed with Study Chair.
  • Tumour profiling should be performed as close to the time of study enrolment as possible; at a minimum profiling should have been performed on a sample obtained within 12 months prior to enrolment, or had confirmation that the targeted molecular aberration is still present from a tumour sample collected within the 12 months prior to enrolment. Patients for whom tumour profiling has been performed outside this window may only be enrolled after approval by the Study Chairs.
• Patients are eligible to enrol using existing sequencing results or other criteria such as immunohistochemistry (provided a report from a CLIA‐approved or equivalent laboratory is provided), but concurrent enrolment on a precision medicine study is still required.  
• Patients enrolled in a Phase I cohort must have either evaluable or measurable disease.
• Patients enrolled in a Phase II cohort must have measurable disease. Evaluable and measurable disease are defined by standard imaging criteria (RECIST V1.1, RAPNO or RANO) for the patient's tumor type.

Additional Inclusion Criteria for Arm A

Study Description

 This study is eligible for STEP-1 funding. Find more information here. 

This is a phase I dose-finding trial of an autologous CD22 targeting chimeric antigen receptor (CAR)-T cell product, called CLIC-2201, for participants with relapsed/refractory B cell malignancies. In the proposed trial, eligible enrolled participants will undergo leukapheresis for autologous T cell collection to enable CLIC-2201 manufacturing, followed by lymphodepletion with cyclophosphamide and fludarabine, then intravenous infusion of the autologous CLIC-2201 product. The trial will use the 3+3 design to escalate or de-escalate the dose level of CLIC-2201 administered. Participants will be monitored for safety and tolerability up to day 365 following CLIC-2201 infusion.

The primary objective is to evaluate the safety and tolerability of CLIC-2201 and estimate the maximum tolerated dose (MTD) of CLIC-2201 in B-cell malignancies.

The secondary objectives are to evaluate the (i) feasibility; (ii) anti-tumour activity of CLIC-2201; (iii) and characterize the pharmacokinetic (PK) profile of CLIC-2201.

Exploratory objectives will include: i) characterizing the cellular and humoral immune responses against CLIC-2201 up to 1 year following infusion of CLIC-2201; (ii) characterizing the phenotype and gene expression profile of CLIC-2201 cells; (iii) evaluating immune and tumour cells at baseline and relapse for biomarkers of response or toxicity; (iv) evaluating serum cytokines, circulating tumour DNA (ctDNA) and B cell aplasia as biomarkers of clinical outcomes; and (v) assessing the quality of life.

Study Description

ACTEMRA (tocilizumab) is an IL-6 receptor antagonist used for the treatment of adult Rheumatoid Arthritis as well as Polyarticular (PJIA) and Systemic (SJIA) Juvenile Idiopathic Arthritis. In this Phase II, the drug will be used to treat pediatric patients diagnosed with recurrent Adamantinomatous Craniopharyngioma including patients who have undergone surgery and/or radiation therapy.

Adamantinomatous Craniopharyngioma (ACP) is a highly debilitating pediatric brain tumor that lacks medical anti-tumor therapies. Current therapy, which depends largely on surgery and radiation, is associated with poor quality of life and becomes more challenging and risky in the setting of recurrent disease. Recent discoveries regarding the biological characteristics of ACP indicate that available agents, including IL-6 pathway blockers may have efficacy in the control of ACP. We hypothesize that the IL6- receptor antagonist ACTEMRA (tocilizumab) will be safe and effective at inducing tumor response in children with residual ACP.

In this study, up to 38 patients will receive tocilizumab at the dose approved for pediatric Systemic Juvenile Idiopathic Arthritis (< 30 kg: 12 mg/kg IV every 2 weeks; ≥30 kg: 8 mg/kg IV every 2 weeks). Therapy may continue for up to two years (26 cycles).

It will be a multi-center Phase 2 trial with two strata for patients aged >1 year and <25 years with unresectable ACP who may have been previously treated with radiation (Stratum 1, 18 patients) or without radiation (Stratum 2, 18 patients).

Inclusion Criteria

1. Age: Patients must be ≥ 12 months and ≤ 25 years of age at the time of study enrollment.
