Official title: A Pilot Trial of Bridging Radiation Therapy With Oral Vancomycin for Patients With B-cell Lymphomas Undergoing CAR-T Therapy
Run by Abramson Cancer Center at Penn Medicine · NCT07478848 · Data updated 2026-11-12
This trial tests if giving radiation and the antibiotic vancomycin before CAR-T cell therapy is feasible for adults with large B-cell lymphomas.

Is this trial a fit for you?
✓Likely a good fit
Adults with pathologically confirmed large B-cell lymphoma who are planned to receive standard-of-care CAR-T therapy and have disease sites amenable to radiation.
✕Probably not a fit
Patients without measurable disease or those not proceeding to CAR-T after the bridging strategy may not experience benefit.

What this trial studies
This Phase 1 interventional study explores whether a bridging strategy using radiation therapy combined with oral vancomycin is feasible prior to standard anti-CD19 CAR-T treatment in adults with large B-cell non-Hodgkin lymphoma. Eligible patients have measurable disease, at least one site suitable for radiation, and are candidates for CAR-T therapy. The approach aims to modulate the disease environment before CAR-T and assess practical aspects such as safety and logistics. Primary goals focus on feasibility, with secondary observations on preliminary safety and treatment response. This is conducted at the Abramson Cancer Center with collaboration from the NCI.
Why it matters
Potential benefit: If successful, patients may receive a safe and streamlined bridging approach prior to CAR-T that could improve disease control and treatment readiness.
How similar studies have gone: Prior small studies in similar bridging or combination approaches have shown mixed but encouraging signals for feasibility and safety in CAR-T settings.

Inclusion Criteria: * Male or female subject aged ≥ 18 years. * Pathologically confirmed B-cell lymphoma patients intended for standard of care CAR-T * ECOG Performance Status ≤ 2. * Subjects must be clinically eligible to receive standard of care anti-CD19 CAR-T * Subjects must have at least one site of disease amenable to radiation, with the ability to deliver radiation to at least 50% of involved sites * Subjects must have at least one site of measurable disease based on CT or FDG PET * Subjects must not be anticipated to require additional therapy beyond bridging radiation listed in this protocol for control of their lymphoma * For female subjects: Negative pregnancy test or evidence of post-menopausal status. The post-menopausal status will be defined as having been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: Women \< 50 years of age: amenorrheic for ≥ 12 months following cessation of exogenous hormonal treatments; and luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution; or Underwent surgical sterilization (bilateral oophorectomy or hysterectomy). Women ≥ 50 years of age: amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments; or had radiation-induced menopause with last menses \>1 year ago; or had chemotherapy-induced menopause with last menses \>1 year ago; or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy, or hysterectomy). * Able to provide informed consent and willing to sign an approved consent form that conforms to federal and institutional guidelines. * Stated willingness to comply with all study procedures and availability for the duration of the study Exclusion Criteria: * Unable to take oral vancomycin for any reason, including: Allergy or Inability to swallow drug * Known history of vancomycin resistant enterococcus (VRE) * Contraindications to radiation therapy, including scleroderma, systemic lupus erythematosus, Crohn disease, ulcerative colitis, or idiopathic pulmonary fibrosis * History of radiation pneumonitis or other grade 4 radiation-related adverse event * Prior or concurrent malignancy whose natural history or treatment which has the potential to interfere with the safety or efficacy assessment of the radiation therapy are eligible for this trial. * Severe, uncontrolled, significant intercurrent or recent illness that would exclude them from being a candidate for standard-of-care CART therapy. * Known uncontrolled HIV infection with a detectable viral load at the time of screening. Note: Patients on effective antiretroviral therapy or who will plan on going on antiretroviral therapy at the time of screening are eligible for this trial. HIV testing is not required for eligibility. * Active infection that required the use of antibiotics within 4 weeks prior to registration * Any other condition that would, in the investigator's judgment, contraindicate the subject's participation in the clinical study due to safety concerns or compliance with clinical study procedures
