Study Details

Brief summary:

This study will evaluate BCB-276, an investigational B7-H3-targeted Chimeric Antigen Receptor (CAR) T cell therapy, in children and young adults with diffuse intrinsic pontine glioma (DIPG). DIPG is a rare and aggressive brain tumor with limited treatment options. CAR T cell therapy uses a patient's own immune cells that are changed in a laboratory to recognize and attack cancer cells. The purpose of this study is to determine whether BCB-276, when given after completion of standard radiation therapy, is safe and can improve survival for patients with DIPG.

To participate, individuals must be between 1 and 26 years of age when they join the study, have a diagnosis of DIPG, and enroll for treatment within 6 weeks of completing initial radiation therapy. Participants must not have received prior anti-cancer therapy beyond radiation with or without temozolomide prior to joining this study.

BCB-276 is administered intraventricularly (into the fluid around the brain), which requires placement of a catheter for treatment. BCB-276 is given every 2 weeks at a research center over a period of several months (approximately 7-8 months). Participation includes travel to a study site, procedures to support treatment administration, sample collection, and ongoing monitoring for safety and effectiveness, with follow-up visits lasting up to about 2 years.

Eligibility Criteria

Sex: All

Age: 1 - 26

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Participants must be aged 1 and ≤ 26 years and weigh ≥10kg.
  • Diagnosis of Diffuse Intrinsic Pontine Glioma (DIPG) based on imaging, with or without biopsy confirmation consistent with high-grade glioma or diffuse midline glioma
  • Able to tolerate leukapheresis and other study procedures in the opinion of the Investigator.
  • Central Nervous System (CNS) reservoir catheter present prior to first dose of study drug.
  • Participant must have completed standard radiation therapy within 6 weeks of enrollment for participation.
  • Performance Status of ≥ 60; mild to moderate restriction or better. Lansky (under 16 years of age) or Karnofsky (16 years of age or older).
  • Adequate organ function and overall clinical status to participate, including stable or improving neurologic symptoms.
  • Participants of childbearing/fathering potential must agree to use highly effective contraception from the time of enrollment through 12 months following the last T cell infusion.
  • Participants with ventriculoperitoneal (VP) shunts need to have a programable system and be able to tolerate temporary adjustment of the shunt required for study treatment.
  • Participant must meet all other health and safety criteria defined in the study protocol.
  • Participant and/or authorized legal representative willing to provide consent/assent for study participation, including participation in the 15-year long term follow up period.

Exclusion Criteria:

An individual who meets any of the following criteria will be excluded from participation in this study:

  • Previous tumor-directed therapy or treatment-directed clinical study other than standard radiation with or without temozolamide.
  • Evidence of metastatic disease.
  • Requirement of high or increasing doses of corticosteroids prior to participation.
  • Severe swallowing difficulties or other significant clinical conditions that may interfere with participation.
  • Presence of an active malignancy other than DIPG.
  • Active or uncontrolled human immunodeficiency virus (HIV), hepatitis B, or hepatitis C infection based on protocol-required laboratory testing.
  • Pregnant or breastfeeding.
  • Presence of any condition that, in the Investigator's opinion, would prohibit the participant from undergoing treatment under this protocol.

Interventions and Outcome Measures

Arms

experimental: BCB-276 CAR-T therapy for newly diagnosed DIPG patients post-radiation therapy

Participants will receive up to 15 intraventricular administrations of BCB-276 delivered every 14 days (+/- 2 days) for an approximate total duration of 30 weeks.

Interventions

BCB-276

Following completion of standard radiation therapy, eligible participants with DIPG will undergo leukapheresis, a procedure to collect white blood cells used to manufacture BCB-276, an autologous CAR T cell therapy made from the participant's own immune cells designed to target B7-H3.

All eligible participants will receive up to 15 intraventricular administrations of BCB-276 every 2 weeks for an approximate total duration of 30 weeks.

Primary outcome measure

  • Overall Survival [ Time Frame: Overall Survival (OS) as defined as time from the date of enrollment to death from any cause (up to 24 months from date of enrollment). ]
