NCT05762419

Brief Summary

The blood brain barrier (BBB) prevents some drugs from successfully reaching the target tumor. Focused Ultrasound (FUS) using microbubbles and neuro-navigator controlled sonication is a non-invasive method of temporarily opening up the blood brain barrier to allow a greater concentration of the drug to reach into the brain tumor. This may improve response and may also reduce system side effects in the patient. The primary purpose of this study is to evaluate the feasibility of safely opening the blood brain barrier in children with progressive diffuse midline gliomas (DMG) treated with oral etoposide using focused ultrasound with microbubbles and neuro-navigator-controlled sonication. For the purpose of the study, the investigators will be opening up the blood brain barrier temporarily in one or two locations around the tumor using the non-invasive focused ultrasound technology, and administrating oral etoposide in children with progressive diffuse midline glioma.

Outcome Measures

Primary Outcomes (2)

  • Number of total adverse events

    This is to evaluate the safety of using focused ultrasound to open the blood brain barrier at one or two sites for administration of etoposide in children with progressive diffuse midline glioma. Safety will be assessed by adverse events as per the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 (including abnormalities from physical and neurologic examinations, laboratory values, and radiographic results).

    Up to 90 days after the end of the last focused ultrasound treatment

  • Number of patients with successful opening of the blood brain barrier

    This is to evaluate the feasibility of using FUS to open the blood brain barrier at one or two sites for administration of etoposide in children with progressive diffuse midline glioma. The study defines feasibility as successful opening of the blood brain barrier.

    Treatment will consist of up to 4 cycles, each lasting 28 days. During the first 2 weeks of each cycle, subjects will receive FUS therapy for a maximum of 3 times per week, concurrent with etoposide.

Secondary Outcomes (4)

  • 3-month Progression Free Survival (PFS3)

    Up to 3 months after last focused ultrasound treatment

  • 3-month Overall Survival (OS3)

    Up to 3 months after last focused ultrasound treatment

  • Blood brain barrier/Tumor imaging changes

    Up to 90 days after the end of the last focused ultrasound treatment

  • Number of severe or serious adverse events

    Up to 90 days after the last focused ultrasound treatment

Study Arms (1)

Focused ultrasound using oral etoposide

EXPERIMENTAL

All patients enrolled in the study will be treated with oral etoposide after receiving focused ultrasound (FUS) treatment with microbubbles and neuro-navigator-controlled sonication.

Drug: Etoposide; Oral, 50 MgDevice: Focused ultrasound with neuro-navigator-controlled sonication

Interventions

Subjects will receive focused ultrasound sonication followed by once daily oral etoposide (50mg/m\^2/dose). Oral etoposide will be taken every day for 21 days, followed by one week of rest. For the first cycle, etoposide will be administered immediately following confirming of the blood brain barrier opening through contrast magnetic resonance imaging (MRI) which will occur within 4 hours of the focused ultrasound procedure. For subsequent cycles, etoposide will be administered immediately following the focused ultrasound procedure. Subjects may continue for a maximum of 4 cycles.

Also known as: Etoposide phosphate
Focused ultrasound using oral etoposide

Focused ultrasound sonication will be performed a maximum of three times a week for two weeks with two weeks of rest.

Eligibility Criteria

Age4 Years - 21 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Ages 4 - 21 years

Subjects must have evidence of clinical and/or radiographic progression of disease.
  • Lansky performance status score of at least 60 for subjects 16 years of age or younger.

Abstinence is an acceptable method of birth control. Women of childbearing potential will be provided a routine quantitative beta-human chorionic gonadotropin (B-hCG) test during the pre-study phase, prior to enrollment and each cycle.
