En undersøgelse af strålebehandling før CAR T-celleterapi til mennesker med B-celle lymfom

3. november 2026 opdateret af: Memorial Sloan Kettering Cancer Center

Et Fase I-studie af Split-Course Bridging Radiotherapy (SC-BRT) forud for kommerciel CD19 CAR T-celleterapi til patienter med recidiverende eller refraktære B-celle lymfomer

The purpose of this study is to test whether radiation therapy given before standard CAR T cell therapy is a safe and effective treatment for people with relapsed and refractory B cell lymphoma. The researchers will also study whether radiation therapy used in this study is a practical treatment option before standard CAR T cell therapy.

Beskrivelse

Inclusion Criteria:

  • Histologically confirmed, relapsed or refractory non-Hodgkin lymphoma patients eligible for a CAR T-cell therapy, such as DLBCL (including transformed follicular lymphoma), high grade B-cell lymphoma, primary mediastinal B-cell lymphoma, and follicular lymphoma of any grade
  • Patient is approved for, and planned to receive, anyone of the three commercially available anti-CD19 CAR T-cell products (axicabtagene ciloleucel, maraleucel or tisagenlecleucel)
  • Patient has at least one site of disease with avidity greater than liver on a screening FDG-PET scan performed within 2 months of RT simulation. Measurable disease is not required.
  • Active secondary central nervous system (CNS) lymphoma is allowed
  • Age 18 or older
  • ECOG status ≤2
  • Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile or abstain from sexual activity for the course of the study through 120 days after the last dose of radiotherapy. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year. Note: Abstinence is acceptable if this is the established and preferred contraception for the subject
  • Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy. Note: Abstinence is acceptable if this is the established and preferred contraception for the subject

Exclusion Criteria:

  • Subject is planned to receive any systemic therapy after initiation of BRT and before re-infusion of CAR T cells including conventional chemotherapy, immunotherapy or targeted agents [Note: Planned lymphodepletion chemotherapy in preparation for CAR T cell administration is not an exclusion criterion]
  • Subject has received prior RT to any site(s) planned for bridging therapy such that the composite dose considering the protocol-mandated BRT would exceed normal tissue tolerances in the determination of the investigator.
  • The treating investigator deems that it would be impossible to comprehensively treat the patient with radiotherapy given concerns about feasibility or potential toxicities
  • Current or planned pregnancy
  • Known additional malignancy that is progressing or requires any treatment other than active surveillance or hormonal therapy. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy.
  • Subject has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study based on the investigator´s judgment

Eksperimentel: Radiation Therapy Before CAR T Cell Therapy

For the purposes of this protocol, day 0 will be considered the date of planned CAR T infusion. BRT Part I (intervention is 9 fractions of 3 Gy to a total dose of 27 Gy). Post-BRT Phase I re- evaluation period: Following delivery of the first 9- fractions of BRT, patients will have a period for recovery, and undergo protocol-mandated reassessment (e.g., PET scan and biopsy). Patients will receive standard of care lymphodepleting chemotherapy. Substitutions to the lymphodepleting regimen will be permitted at the discretion of the treating investigator. Day -2: BRT Part II (intervention is one fraction 3 Gy to receive a total dose of 3 Gy). Day -1: No protocol scheduled treatment interventions. Day 0: Subject will receive standard of care infusion of a manufactured commercial CAR T-cell product, as an inpatient or outpatient, at the discretion of the treating investigator.

RT Part I. The target will be to complete the 9th fraction of radiotherapy (i.e., total of 27Gy) between days -12 and -8 Day -2: BRT Part II (intervention is one fraction 3 Gy to receive a total dose of 3 Gy).

Day -5 to -3: Patients will receive standard of care lymphodepleting chemotherapy

Day 0: Subject will receive standard of care infusion of a manufactured commercial CAR T-cell product.
