About this trial

This phase I/II trial studies the best dose of total body irradiation with astatine-211 BC8-B10 monoclonal antibody for the treatment of patients with nonmalignant diseases undergoing hematopoietic cell transplant. Radiation therapy uses high energy gamma rays to kill cancer cells and shrink tumors. Astatine-211-labeled BC8-B10 monoclonal antibody is a monoclonal antibody, called anti-CD45 monoclonal antibody BC8-B10, linked to a radioactive/toxic agent called astatine 211. Anti-CD45 monoclonal antibody BC8-B10 is attached to CD45 antigen positive cancer cells in a targeted way and delivers astatine 211 to kill them. Giving astatine-211 BC8-B10 monoclonal antibody and total-body irradiation before a donor stem cell transplant may help stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells.

Eligibility criteria

Qualifiers

Age >= 18 years and < 50 years

Nonmalignant disease treatable by allogeneic hematopoietic cell transplantation (HCT). Patients with a nonmalignant disease that is not clearly defined must be approved by the principal investigator (PI)

Karnofsky score >= 70

Patients must have normal elastography

Disqualifiers

Patients with Fanconi Anemia

Impaired cardiac function as evidenced by ejection fraction < 35% (or, if unable to obtain ejection fraction, shortening fraction of < 26%) or cardiac insufficiency requiring treatment or symptomatic coronary artery disease. Patients with a shortening fraction of < 26% may be enrolled if approved by a cardiologist. In addition, patients with poorly controlled hypertension on multiple anti-hypertensive medications, symptomatic coronary artery disease, or patients on cardiac medications for antiarrhythmic or inotropic effects are excluded

Impaired pulmonary function as evidenced by carbon monoxide diffusing capability test (DLCO) < 35% of predicted or receiving supplemental continuous oxygen. In addition, if patients are unable to perform pulmonary function tests, then O2 saturation < 92% on room air

Impaired renal function as evidenced by estimated creatinine clearance less than 50 ml/min or serum creatinine > 2 x upper normal limit or dialysis-dependent. Serum creatinine value must be within 28 days prior to start of conditioning
