Ultra-Rapid Profiling and Drug Screening for Treatment Selection in Patients With Relapsed or Recurrent Rare Brain Tumors (SUPERNOVA-RBT)

October 12, 2026 updated by: Adriana Fonseca

A Pilot Trial of Screening and Ultra-Rapid Profiling to Enable Real-Time Neuro-Oncology Validation and Actionable Treatment Selection for Patients With Relapsed or Recurrent Rare Brain Tumors

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 in of performing real-time drug screening on tissue taken during surgery in patients with relapsed ultra rare brain tumors (BCOR -altered, MN1-altered, CNS Sarcomas, other rare brain tumors) and of having a specialized tumor board assign a treatment plan based on the results of the drug screening and genomic sequencing. The aim of this trial is to allow every child and young adult with relapsed ultra rare brain tumors 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. Moreover, if successful, it could serve as a paradigm for personalized medicine programs for other types of cancer.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Following clinically indicated biopsy or resection, fresh tissue will be submitted for real-time high-throughput drug screening and tumor/paired-normal molecular profiling will be initiated. A specialized tumor board will issue a documented management recommendation within 28 days . Recommendations will integrate successful drug screening, all molecular/pathology data available at the time of review, prior therapy, and clinical context. Later molecular results may prompt an addendum. The treating physician retains responsibility for final treatment decisions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 45 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  2. Participant must be a candidate for surgical resection or biopsy.

    • Participants must have surgically accessible disease.

  3. Prior therapy

    • The participant must have a relapsed or recurrent rare brain tumor following at least one prior therapy for initial diagnosis or previous recurrence prior to study registration:

    • Biologic agent: Participant must have recovered from any toxicity potentially related to the agent.
    • Last radiation at least 7 days prior to therapy start

  5. Karnofsky 50 for participants > 16 years of age and Lansky 50 for participants <16 years of age

  6. Corticosteroids: Subjects who are receiving dexamethasone or equivalent must be on a stable or decreasing dose for at least 1 week prior to therapy start.

  7. The effects of the agents used in this study on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and 4 months after completion of therapy administration.

  8. Adequate neurologic function defined as:

    • Participants with seizure disorders may be enrolled if seizures are well controlled. Participants on non-enzyme inducing anticonvulsants may be excluded pending interaction(s) with study drug.

  9. A legal parent or guardian must be able to understand and agree to sign a written informed consent and assent document, as appropriate.

Exclusion Criteria:

  1. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection.
  2. Women of childbearing potential must not be pregnant or breast-feeding. A negative serum or urine pregnancy test is required prior to start of therapy.
