Study of IOMAB-ACT Followed by CAR-T Cell Therapy for Patients Relapsed or Refractory (Diffuse Large B-cell Lymphoma

Is NCT06768905 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments including Iomab-B and CAR-T cell for non hodgkin lymphoma.

Phase 1/2RecruitingUniversity of Texas Southwestern Medical CenterNCT06768905Data as of May 2026

Treatment: Iomab-B · CAR-T cellThis study is being done to determine the safety, efficacy and tolerability of a single 50 mCi dose of 131I-Apamistamab given prior to CAR-T cell infusion in patients with Relapsed or refractory (R/R) Diffuse large B-cell lymphoma (DLBCL).

Lab requirements

Blood counts

Absolute neutrophil count ≥1.0k/µL, Platelets ≥50k/µL, Hemoglobin ≥8g/dL, without requiring blood product or granulocyte-colony stimulating factor support in the 7 days prior to screening and start of 131I-Apamistamab treatment.

Kidney function

Creatinine clearance ≥50 mL/min as calculated by the Cockroft-Gault formula.

Liver function

Total bilirubin ≤1.5x upper limit of normal, AST and ALT ≤3x upper limit of normal (ULN), unless liver dysfunction is thought to be related to underlying malignancy or secondary to Gilbert's disease in which case the direct bilirubin should be ≤3.0 mg/dL, and AST and ALT ≤5x ULN.

Cardiac function

LVEF ≥40% as assessed by echocardiogram or MUGA scan. Exclude NYHA stage III or IV congestive heart failure, myocardial infarction ≤6 months prior to enrollment, any history of clinically significant ventricular arrhythmia or unexplained syncope.
