NCT ID:
NCT03705858
Eligibility Criteria:
Inclusion Criteria:
1. Subjects must have histologically confirmed AML in first, second, or third clinical CR/CRp after any standard or investigational therapy.
2. Subjects must have detectable MRD by cytogenetics, FISH, or flow cytometry after the completion of all planned therapy. Detectable MRD by flow cytometry is defined by the presence of a myeloid blast population with an atypical immunophenotype, constituting less than 5% of all events. Examples of planned therapy courses include induction chemotherapy with cytarabine and an anthracycline followed by consolidation chemotherapy or 4-6 cycles of a hypomethylating agent-based regimen.
3. At the time of diagnosis or most recent relapse, greater than 25% of bone marrow blasts must have been CD33 positive.
4. Age ≥18 years. Because no dosing or adverse event data are currently available on the use of 225Ac-lintuzumab in patients \<18 years of age, children are excluded from this study.
5. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
6. Subjects must have adequate bone marrow and organ function documented within 14 days of study entry as follows:
1. Absolute neutrophil count (ANC) ≥ 1,000/μL;
2. Platelet count ≥ 50,000/μL;
3. Serum creatinine ≤ 1.5 × upper limit of normal (ULN) or estimated glomerular filtration rate of \> 50 mL/min;
4. Serum total bilirubin ≤ 1.5 × ULN (unless attributable to Gilbert's disease);
5. Alkaline phosphatase, serum aspartate aminotransferase (AST), and serum alanine aminotransferase (ALT) ≤ 2.5 × ULN.
7. The effects of 225Ac-lintuzumab on the developing human fetus are unknown. Since radiation exposure, however, is known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of treatment on study. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of 225Ac-lintuzumab administration.
8. Ability to understand and the willingness to sign a written informed consent document.
Exclusion Criteria:
1. Subjects with acute promyelocytic leukemia or BCR-ABL-positive leukemia.
2. Subjects who have had chemotherapy or radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier. Prior clofarabine is not allowed due to risk of liver dysfunction.
3. Subjects who have previously received 225Ac-lintuzumab.
4. Subjects with an human leukocyte antigen (HLA)-compatible donor or stem cell source who are immediate candidates for allogeneic hematopoietic cell transplantation (HCT).
5. Subjects who are receiving any other investigational agents concurrently.
6. Subjects with active central nervous system (CNS) involvement by AML.
7. Uncontrolled intercurrent illness including, but not limited to, active serious infections uncontrolled by antibiotics, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, documented liver cirrhosis, or psychiatric illness/social situations that would limit compliance with study requirements.
8. Active malignancy within 3 years of study entry, except previously treated melanoma grade 2 or less, non-melanoma skin cancer, carcinoma in situ or cervical intraepithelial neoplasia, and organ confined prostate cancer with no evidence of recurrent or progressive disease based on prostate-specific antigen (PSA) levels and are not on active therapy.
9. Prior organ transplant, including allogeneic HCT.
10. Pregnant or nursing women.
11. Subjects with known human immunodeficiency virus (HIV) infection, active hepatitis B, or active hepatitis C.
