About this trial
This is a pilot study; patients will receive 131-I apamistamab prior to CAR T-cell infusion in order to determine the maximum tolerated dose of 131-I apamistamab is exceeded at 75 mCi, and if so, to assess the safety of a step-down dose of 50 mCi.
Eligibility criteria
Qualifiers
While prior CD19-targeted therapies, including CAR T-cell therapy, do not exclude participation, CD19 expression by immunohistochemical staining or flow cytometry must be confirmed prior to enrollment.
Age ≥ 18 years of age
Creatinine clearance ≥50 mL/min as calculated by the Cockroft-Gault formula
Direct bilirubin ≤2.0 mg/dL, AST and ALT ≤3.0x upper limit of normal (ULN), unless liver dysfunction is thought to be related to underlying malignancy
Disqualifiers
ECOG performance status ≥3.
Pregnant or lactating patients. Patients of childbearing age should use effective contraception while on this study and continue for 1 year after all treatment is finished.
Impaired cardiac function (LVEF <40%) as assessed by echocardiogram or MUGA scan during screening
Patients with active graft versus host disease following allogeneic hematopoietic cell transplantation requiring systemic T-cell suppressive therapy are ineligible
