Study Description

Phase 1 of this study, utilizing a rolling 6 design, will be conducted to determine a maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D), and to describe the toxicities of lenvatinib administered in combination with everolimus once daily to pediatric participants with recurrent/refractory solid tumors [phase 1 has been completed]

Phase 2, utilizing Simon's optimal 2-stage design, will be conducted to estimate the antitumor activity of lenvatinib in combination with everolimus in pediatric participants with selected recurrent/refractory solid tumors including Ewing sarcoma/peripheral primitive neuroectodermal tumor (pPNET), rhabdomyosarcoma, and high grade glioma (HGG) using objective response rate (ORR) at Week 16 as the outcome measure.

Study Description

Brief Summary:

This is a prospective randomized clinical trial, to determine whether dose-intensive tandem Consolidation, in a randomized comparison with single cycle Consolidation, provides an event-free survival (EFS) and overall survival (OS). The study population will be high-risk patients (non-Wnt and non-Shh sub-groups) with medulloblastoma, and for all patients with central nervous system (CNS) embryonal tumors completing "Head Start 4" Induction. This study will further determine whether the additional labor intensity (duration of hospitalizations and short-term and long-term morbidities) associated with the tandem treatment is justified by the improvement in outcome. It is expected that the tandem (3 cycles) Consolidation regimen will produce a superior outcome compared to the single cycle Consolidation, given the substantially higher dose intensity of the tandem regimen, without significant addition of either short-term or long-term morbidities.

Detailed Description:

Due to the inferior response and event-free survival data of Regimens D and D2 on "Head Start III" for all children with supratentorial embryonal tumors, in comparison with the published data from "Head Start II" with Regimen A2 for metastatic patients, all such patients will receive the "Head Start II" Induction Regimen A2, on "Head Start 4", for either three or five cycles, depending upon whether or not they achieve complete remission by the end of Induction cycle #3. They will then undergo randomization to either single cycle or three tandem cycles of Consolidation marrow-ablative chemotherapy with AuHPCR.

Because of the unsatisfactory event-free survival for young children with non-desmoplastic/extensive nodular medulloblastoma (predominantly non-Shh and non-Wnt medulloblastoma subgroups) on Regimens D and D2 of "Head Start III", all these patients will receive the "Head Start II" Induction Regimen A2 on ""Head Start 4"", for either three or five cycles, depending upon whether or not they achieve complete remission by the end of Induction cycle #3. They will then undergo randomization to either single cycle or three tandem cycles of Consolidation marrow-ablative chemotherapy with AuHPCR.

Because of the excellent event-free and overall survival for young children with good risk medullo-blastoma (Shh or Wnt subgroups) treated with up-front "Head Start" chemotherapy strategies, such patients will undergo risk-tailored reduction of duration of Induction therapy from five cycles to three cycles of the "Head Start II" Induction Regimen A2 on "Head Start 4" for patients achieving a complete response to 3 cycles, followed, provided they are also without evidence of residual tumor following recovery from Induction cycle #3. They will NOT then undergo randomization, but will follow with a single cycle of Consolidation marrow-ablative chemotherapy as in "Head Start" studies.

Study Description

Brief Summary:

Many pediatric brain and solid tumors have altered epigenetic landscapes, and altered DNA methylation. As such this study is a Phase I/Ib study of combined 5'Azacitidine with an escalating dose of carboplatin for all recurrent/refractory pediatric brain and solid tumors. The phase I component will establish with maximum tolerated dose of carboplatin with azacytidine. An expansion cohort will be recruited of up to 30 patients will follow consisting of 20 recurrent posterior fossa ependymoma and 10 recurrent supratentorial ependymoma.

Detailed Description:

Aberrant DNA methylation is frequently observed in many pediatric solid tumors, but in particularly several entities such as ependymoma, medulloblastoma, embryonal tumor with multilayered rosettes, atypical/teratoid rhabdoid tumor, neuroblastoma and wilm's tumor have promoter hypermethylation. Treatment with DNMTi (DNA methyltransferase inhibitors) agents such as 5-azacytidine has been shown to be safe and efficacious in adult myelodysplastic syndromes, causing significant decreased DNA methylation in blood, with maximum effect at day 15 of each cycle. However, monotherapy with DNMTi has been shown to result in resistance in leukamia's and efficacy in solid tumours is limited. Synergy between DNMTi and platinum agents has shown promise in pre-clinical models including pediatric ependymoma, and in addition, the combination of demethylating agents with carboplatin has provided promising results in platinum resistant ovarian cancers. However, this approach has not been applied to pediatric solid malignancies, which are attractive targets due to their frequent epigenetic dysregulation.

Platinums are the backbone of therapy for most pediatric solid tumors, and as such it is an attractive hypothesis that part of the reason for resistance to upfront therapies is platinum resistance. Specifically, ependymoma's are highly chemoresistant tumors and studies in preclinical models of ependymoma support that this chemoresistance can be overcome with DNMTi.

There is a clear medical need for new therapies, particularly for relapsed solid tumors, specifically brain tumors. Although pre-clinical data from our group and others suggests DNA demethylase inhibitors to be promising therapies for high risk ependymoma, medulloblastoma and ETMR (embryonal tumor with multilayered rosettes), 5'azacitidine monotherapy has been disappointing in clinical studies of adult solid tumours. Previous studies have suggested that platinum therapy can be effectively combined with azacitidine therapy and based on adult studies, maximum demethylation occurs approximately 5-10 days after treatment with 5'azacitidine. As such combination of azacitidine and carboplatin is a rationale therapy for several pediatric brain tumours, particularly those with a hypermethylated phenotype.

Two phases of the study will be conducted. The Phase I will establish the maximum tolerated dose of carboplatin and 5'azacytidine in a rolling 6 design. 5'azacytidine will be administered on Days 1-7 followed by Carboplatin on Day 15. The initial dose level will be 5'Azacytidine 75mg/m2/day for 7 days with Carboplatin administered on Day 15 at AUC (Area under curve) 4. Carboplatin will be dose escalated to a maximum of AUC 6, or de-escalated to AUC 3. The Phase Ib will be an ependymoma specific expansion cohort at the established MTD (maximum tolerated dose), to determine the feasibility and initial efficacy of the combination of carboplatin and 5'azacytidine in patients with recurrent/refractory posterior fossa and supratentorial ependymoma.

Study Description

This is a 4-part (Part A, Part B, Part C and Part D), Phase I/IIa, multi-center, open label, study in pediatric subjects with refractory or recurrent tumors.

Part A is a repeat dose, dose escalation monotherapy study that will identify the recommended phase II dose (RP2D) on the continuous dosing schedule using a 3 + 3 dose- escalation procedure.

Part B will evaluate the preliminary activity of trametinib monotherapy in 4 disease-specific cohorts of subjects. Each cohort will enroll at least 10 response-evaluable subjects (evaluable for response is defined as a subject with a pre-dose and at least 1 post-dose disease assessment or clinical assessment of progression of disease).

Part C is will be a 3+3 study design to determine the safety, tolerability and preliminary activity of the RP2D of trametinib in combination with a limited dose escalation of dabrafenib. Part C will enroll up to 24 subjects.

Part D will evaluate the preliminary activity of trametinib in combination with dabrafenib in 2 disease-specific cohorts of subjects diagnosed with LGG and LCH. LGG cohort will enroll approximately 20 response-evaluable subjects and the LCH cohort will enroll approximately 10 response-evaluable subjects.

The overall goal of this trial is to efficiently establish safe, pharmacologically relevant dose of trametinib monotherapy and trametinib in combination with dabrafenib in infants, children and adolescents and determine preliminary activity of trametinib monotherapy and trametinib in combination with dabrafenib in selected recurrent, refractory or unresectable childhood tumors.

This study is currently open for LCH and neuroblastoma only.

Study Description

This is an open-label, single arm, multi-center, pilot study of Nivolumab in pediatric patients with recurrent or refractory hypermutant malignancies aged 12 months to 18 years of age. This study is to assess clinical and radiological benefits of treatment with Nivolumab in children with hypermutated cancers, including those with bMMRD syndrome. It is our expectation that patients with bMMRD syndrome will account for the majority of patients enrolled on this study.

Nivolumab (also referred to as BMS-936558 or MDX1106) is a human monoclonal antibody (HuMAb; immunoglobulin G4 [IgG4]-S228P) that targets the programmed death-1 (PD-1) cluster of differentiation 279 (CD279) cell surface membrane receptor. Nivolumab will be administered every 14 days until disease progression or treatment discontinuation due to unacceptable toxicities. Treatment may extend up to 2 years in patients who show clinical and radiological benefit (dose: 3 mg/kg intravenously as a continuous infusion over 60 min).

Primary Outcome Measures  :

  1. To evaluate the objective response rate to Nivolumab in bMMRD positive pediatric patients with refractory hypermutated malignancies 

    Objective response rate will assessed by physical assessments, lab values, disease assessments and adverse events that are related to treatment. Scheduled time-points and the above assessments are detailed further in section "9.1 Study Calendar" of the protocol.

  2. To evaluate the objective response rate to Nivolumab in bMMRD positive pediatric patients with recurrent hypermutated malignancies.

    Objective response rate will assessed by physical assessments, lab values, disease assessments and adverse events that are related to treatment. Scheduled time-points and the above assessments are detailed further in section "9.1 Study Calendar" of the protocol.

  3. Estimating the feasibility of using Nivolumab as a treatment in bMMRD positive, pediatric patients with refractory or recurrent hypermutated malignancies. Feasibility of treatment will be measured using a patient's disease response assessment. This means using standard RECIST criteria for solid tumours, iRANO/RANO criteria for CNS malignancies and the revised AML International Working Group (IWG) Criteria for haematological malignancies; modified RECIST criteria for immune response may be considered during the time of study.

Secondary Outcome Measures  :

  1. The progression free survival (PFS) of pediatric patients with progressive or recurrent hypermutated malignancies including bMMRD patients treated with Nivolumab.
  2. Number of Participants with Abnormal Laboratory Values and/or Adverse Events That Are Related to Treatment. These will be assessed by abnormal findings in physical assessments, lab values, disease assessments and adverse events

 Time Frame: 5 years (60 months) from date of enrollment
