Testing Nivolumab in Combination With Decitabine and Venetoclax in Patients With Newly Diagnosed TP53 Gene Mutated Acute Myeloid Leukemia

• Status: Suspended
• Trial end date: 2022-02-28
• Target enrollment: 0
• Participant gender: All

Summary

This trial studies the side effects of nivolumab in combination with decitabine and venetoclax and to see how well they work in treating patients with TP53-mutated acute myeloid leukemia. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as decitabine and venetoclax, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This study is being done to find out whether giving nivolumab, decitabine, and venetoclax is better or worse than the usual approach for TP53-mutated acute myeloid leukemia.

Criteria

Inclusion Criteria:

• Patients must have histologically or cytologically confirmed acute myeloid leukemia (AML)

• Presence of TP53 mutation at diagnosis

• Newly diagnosed, untreated AML

• Patients who received prior hypomethylating therapy for a prior myelodysplastic syndrome (MDS) diagnosis are allowed

• Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)

• Total bilirubin =< 1.5 x institutional upper limit of normal (ULN), (except for patients with Gilbert's disease)

• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 5 x institutional ULN

• Glomerular filtration rate (GFR) > 40 mL/min/1.73 m^2

• Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial

• For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated

• Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load

• Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial

• Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association functional classification. To be eligible for this trial, patients should be class 2B or better. A baseline troponin should be within normal limits and baseline oxygen saturation should be greater than or equal to 92%. A baseline electrocardiogram (ECG) should be normal, or with stable changes if patient has chronic ECG changes

• Active infection is permitted if the infection is under control

• White blood count (WBC) must be =< 25,000 at time of day 1 of study treatment. Cytoreduction with Hydrea and leukapheresis is allowed

• Risks from venetoclax and nivolumab to the developing human fetus cannot be ruled out. For this reason and because decitabine 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 study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Contraception use should be continued 6 months after the completion of all study treatments for women of child bearing potential. 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 7 months after completion of decitabine, venetoclax, or nivolumab administration

• Ability to understand and the willingness to sign a written informed consent document. Patients with impaired decision-making are allowed to participate as long as the patient has a legally authorized representative (LAR) or caregiver

Exclusion Criteria:

• Patients with history of prior allogeneic transplantation. This is due to this being a pilot study with a limited number of patients

• Patients with known autoimmune disease. Patients with active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids, should be excluded. These include but are not limited to patients with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, myasthenia gravis; systemic autoimmune disease such as systemic lupus erythematosus (SLE), connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis, hepatitis; and patients with a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome should be excluded because of the risk of recurrence or exacerbation of disease. Patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible. Patients with rheumatoid arthritis and other arthropathies, Sjogren's syndrome and psoriasis controlled with topical medication and patients with positive serology, such as antinuclear antibodies (ANA), anti-thyroid antibodies should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible

• Patients are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger (precipitating event)

• Patients should be excluded if they have a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses =< 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease. Patients are permitted to use topical, ocular, intra-articular, intranasal, and inhalational corticosteroids (with minimal systemic absorption). Physiologic replacement doses of systemic corticosteroids are permitted, even if =< 10 mg/day prednisone equivalents. A brief course of corticosteroids for prophylaxis (e.g., contrast dye allergy) or for treatment of non-autoimmune conditions (e.g., delayed-type hypersensitivity reaction caused by contact allergen) is permitted

• Patients with hyperleukocytosis requiring immediate cytoreductive chemotherapy (WBC >= 100,000 with symptoms of leukostasis)

• Isolated extramedullary leukemia of central nervous system (CNS) involvement with leukemia

• Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1) with the exception of alopecia

• Patients who are receiving any other investigational agents

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to decitabine, venetoclax, or nivolumab

• Patients with uncontrolled intercurrent illness

• Patients with psychiatric illness/social situations that would limit compliance with study requirements

• Pregnant women are excluded from this study because fetal risk has been demonstrated with decitabine with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with decitabine, breastfeeding should be discontinued if the mother is treated with decitabine. These potential risks may also apply to other agents used in this study
