Study Details

Study Description

Brief Summary

The current study will use a new treatment approach based on the molecular characteristics of each participant's tumor. The study will test the feasibility of performing real-time drug screening on tissue taken during surgery, and of having a specialized tumor board assign a treatment plan based on the results of this screening and genomic sequencing. The aim of this trial is to allow every child and young adult with medulloblastoma to receive the most effective and least toxic therapies currently available, and will pave the way for improved understanding and treatment of these tumors in the future.

N/A

Detailed Description

This is a single arm multi-center pilot trial within the Pacific Pediatric Neuro-Oncology Consortium (PNOC). Relapsed participants will receive an individualized treatment recommendation including up to four FDA-approved drugs based on the results of real-time high-throughput drug screening, whole exome sequencing (WES), and RNA sequencing.

PRIMARY OBJECTIVE:
  1. To determine the feasibility of using the results of real-time in vitro drug screening, whole exome sequencing, and RNA sequencing of participant-derived specimens to guide treatment recommendations by a specialized tumor board, in a clinically-actionable timeframe, for children and young adults with recurrent medulloblastoma.
SECONDARY OBJECTIVE:
  1. To determine the safety and describe the toxicity of treating children and young adults with relapsed medulloblastoma according to a specialized tumor board that makes treatment recommendations based on real-time drug screening and genomic sequencing.
EXPLORATORY OBJECTIVES:
  1. To estimate the objective response rate, progression free survival at 6 months (PFS-6) and overall survival (OS) of relapsed medulloblastoma in children and young adults treated with an individualized treatment regimen.

  2. To assess Quality of Life (QOL) measures in participants with relapsed medulloblastoma treated with an individualized regimen.

  3. To archive tumor and normal DNA from each participant along with serial blood draw following therapies as biospecimens for later studies to determine whether circulating tumor DNA (ctDNA) sequences in the participant's blood serve as biomarkers of tumor burden, response to therapy, or development of drug resistance.

Participants may continue treatment as tolerated for up to two years or until disease progression. Participants will be followed until progression, death, or up to 5 years from start of therapy.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Individualized Treatment Recommendation

Participants will receive an individualized treatment recommendation including a combination of up to four FDA-approved drugs within 21 business days of tissue acquisition using the results of real-time high-throughput drug screening, whole exome sequencing (WES), and RNA sequencing.

Other: Specialized Tumor Board Treatment Plan
Specialized Treatment Plan of up to four FDA approved drugs based on participant's screening results will be assigned by PNOC specialized tumor board

  • Specialized Treatment Plan
  • Outcome Measures

    Primary Outcome Measures

    1. Median Time from tissue collection to issued treatment plan from the specialized tumor board [Up to 21 days]

      Time to tissue collection will be used to determine the feasibility of using the results of real-time in vitro drug screening, WES and RNAseq of participant-derived specimens to guide treatment recommendations by a specialized tumor board, in a clinically-actionable timeframe, for children and young adults with recurrent medulloblastoma. Participants are expected to receive treatment plan within 21 business days

    Secondary Outcome Measures

    1. Proportion of participants with Adverse Events [Up to 2 years]

      Proportion of participants with grade 3 or higher toxicities classified according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Adverse events and clinically significant laboratory abnormalities (meeting Grade 3 or higher criteria will be summarized by maximum grade and relationship to study drug(s).

    Inclusion Criteria:
    1. Participants must have recurrent medulloblastoma.

    2. Participants must have surgically accessable disease.

    3. Prior Therapy:

    4. The participant must have recurrent medulloblastoma following at least one prior therapy for initial diagnosis or previous recurrence- surgery followed by high dose chemotherapy with stem cell rescue or multi-modality therapy of surgery, radiation and chemotherapy - prior to study registration.

    5. Participants must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.

    • Myelosuppressive chemotherapy: Participants must have received their last dose of known myelosuppressive anti-cancer chemotherapy at least 3 weeks prior to study registration (6 weeks prior if nitrosourea).

    • Biologic agent: Participant must have recovered from any toxicity potentially related to the agent and received their last dose of the biologic agent no less than 7 days prior to study registration.

    • For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended to beyond the time during which adverse events are known to occur. The duration of this interval should be discussed with the study chair.

    • For biologic agents that have a prolonged half-life, the appropriate interval since last treatment should be discussed with the Study Chair prior to registration.

    • Monoclonal antibody treatment: At least three half-lives must have elapsed prior to registration. Such participants should be discussed with the study chair prior to registration. For bevacizumab, participants must have received last dose > 32 days prior to study registration.

    • Bone Marrow Transplant: Participant must be >= 6 months since allogeneic bone marrow transplant prior to registration and >=3 months since autologous bone marrow/stem cell prior to registration.

    1. Participant must be a candidate for surgical resection or biopsy. Minimum tissue requirements for study are defined in Section 9.1.

    2. Radiation - Participants must have:

    3. Had their last fraction of local irradiation to primary tumor >= 12 weeks prior to registration; investigators are reminded to review potentially eligible cases to avoid confusion with pseudo-progression.

    4. Had their last fraction of craniospinal irradiation or total body irradiation >= 12 weeks prior to registration

    5. At least 14 days after local palliative radiation (small-port)

    6. Age >=12 months to <= 39 years of age.
