Testing the Combination of Nivolumab and ASTX727 for Relapsed or Refractory B-Cell Lymphoma

Exclusion Criteria

• •Patients should be New York Heart Association Functional Classification of class 2B or better
• •The effects of nivolumab and ASTX727 on the developing human fetus are unknown. For this reason and because DNMTi agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential (WOCBP) and men must agree to use highly effective contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. WOCBP should use a highly effective contraception method to avoid pregnancy during treatment with ASTX727 and for at least 6 months after the last dose of investigational drug and must agree not to donate eggs (ova, oocytes) for the purpose of reproduction for the same time period. Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin \[HCG\]) within 24 hours prior to the start of nivolumab. An extension up to 72 hours prior to the start of study treatment is permissible in situations where results cannot be obtained within the standard 24-hour window. Women must not be breastfeeding. Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men who are sexually active with WOCBP will be instructed to adhere to highly-effective contraceptive measures of birth control and not to father a child while receiving treatment and for a period of 3 months after the last dose of investigational product. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception
• •* Women of childbearing potential (WOCBP) is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:
• •* Women \< 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
• •* Women ≥ 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses \> 1 year ago, had chemotherapy-induced menopause with last menses \> 1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
• •WOCBP receiving ASTX727 will be instructed to adhere to contraception for a period of 6 months after the last dose of investigational product. Men receiving ASTX727 and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 3 months after the last dose of investigational product. WOCBP receiving nivolumab as a single agent will be instructed to adhere to contraception for a period of 5 months after the last dose. These durations have been calculated using the upper limit of the half-life for nivolumab (25 days) and are based on the protocol requirement that WOCBP use contraception for 5 half-lives plus 30 days Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she (or the participating partner) should inform the treating physician immediately
• •Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity who have a legally-authorized representative (LAR) and/or family member available will also be eligible
• •Patients who have had chemotherapy or radiotherapy within 4 weeks (2 weeks for Revlimid, 6 weeks for nitrosoureas or mitomycin C) prior to entering the study. Palliative (limited-field) radiation therapy is permitted, if all of the following criteria are met:
• •* Repeat imaging demonstrates no new sites of bone metastases
• •* The lesion being considered for palliative radiation is not a target lesion
• •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 have had prior treatment with anti-PD-1/PD-L1 inhibitors or anti CTLA4 antibodies and were permanently discontinued from further treatment because of an adverse event. All other prior therapies are permissible. Prior checkpoint inhibitor therapy is allowed if there was no discontinuation due to adverse event
• •Patients who are receiving any other investigational agents
• •Patients with known brain metastases or leptomeningeal metastases may be excluded because of poor prognosis and concerns regarding progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
• •History of allergic reactions attributed to compounds of similar chemical or biologic composition to ASTX727 or nivolumab, including severe hypersensitivity reaction to any monoclonal antibody
• •Patients with uncontrolled intercurrent illness
• •Patients with cognitive or other impairment that would prevent compliance with study requirements
• •Pregnant women are excluded from this study because ASTX727 is a DNMTi agent and nivolumab is a PD-L1 inhibitor 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 ASTX727 and nivolumab, breastfeeding should be discontinued if the mother is treated with ASTX727 and nivolumab
• •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 (GBS), 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 who have had evidence of active or acute diverticulitis, intra-abdominal abscess, gastrointestinal (GI) obstruction and abdominal carcinomatosis which are known risk factors for bowel perforation should be evaluated for the potential need for additional treatment before coming on study
