PHASE I (ARMS A, B, C, D, E, F, G, H, I, X, Y, Z):

• Age ≥ 18 years old.
• Patients must have pathologically confirmed relapsed or refractory lassical Hodgkin Lymphoma (cHL). A biopsy at any relapse is acceptable. Other histologies including lymphocyte predominant (LP) HL are not permitted.
• Patients must have relapsed after first line chemotherapy. May have relapsed after autologous or allogeneic stem cell transplant, or have primary refractory disease. No upper limit for number of prior therapies. If status post allogeneic stem cell transplant, no active  graft versus host disease.
• Patients may have received prior brentuximab vedotin, but must not have received brentuximab vedotin within 6 months prior to registration, and must not have relapsed within 6 months of receiving previous brentuximab vedotin. Patients may not have received prior nivolumab or PD1/PDL1 axis agents. Patients in the nivolumab/brentuximab cohorts ONLY (D, E, F, Y) may have received prior ipilimumab.
• Patients may have received other prior activating immunotherapies (i.e., checkpoint inhibitors), but must not have received them within 6 months prior to registration, and there must be no serious unresolved complication of therapy at the time of registration. For the  purposes of this study monoclonal antibodies and antibody drug conjugates are not considered to be activating immunotherapies and there are no additional time restrictions on prior exposure to these agents (except prior brentuximab vedotin).
• ECOG-ACRIN performance status between 0-2.
• Patients must have measurable disease as defined in Section 6. Baseline measurements and evaluations must be obtained within 4 weeks of registration to the study. Abnormal PET scans will not constitute evaluable disease unless verified by a diagnostic quality CT scan. Patients must use the same imaging modality (CT or PET/CT) throughout the study.
• Women must not be pregnant or breast-feeding due to risk of fetal harm by the chemotherapeutic agents prescribed in this protocol. All females of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to rule out pregnancy. A female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria:
  • has not undergone a hysterectomy or bilateral oophorectomy; or
  • has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).
  • Female of childbearing potential? ______ (Yes or No)
  • Date of blood or urine test: ___________
• Women of childbearing potential (WOCBP) and sexually active males must either abstain from sexual intercourse for the duration of their participation in the study or agree to use both single barrier contraception and birth control pills or implants for at least one week prior to the start of the study drug and continuing for 5 months after the last dose of study drug (for female patients) and for 7 months after the last dose of study drug (for male patients who are sexually active with WOCBP).  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.
• Patients must have no evidence of dyspnea at rest and a pulse oximetry > 92% while breathing room air.
• Patients must have FEV1/FVC > 60% by pulmonary function test (PFT), unless due to large mediastinal mass from HL. Carbon monoxide diffusion capacity (DLCO), FEV1, and FVC all >50% predicted value. All pulmonary function tests must be obtained within one month prior to registration.

  • Calculated creatinine clearance by Cockroft-Gault formula  ≥ 30 ml/min.
• No evidence of prior malignancy except adequately treated nonmelanoma skin cancer, in situ cervical carcinoma or any surgically- or radiation-cured malignancy continuously disease free for ≥ 5 years so as not to interfere with interpretation of radiographic response.
• Patient must have no current or prior history of CNS involvement.
• All prior therapy must have been completed at least 21 days prior to enrollment. No concomitant anti lymphoma therapy, including systemic corticosteroids for the purpose of treatment of lymphoma are allowed. Topical steroids are allowed.

• Patients must not have autoimmune disorders or conditions of immunosuppression that require current ongoing treatment with systemic corticosteroids (or other systemic immunosuppressants), including oral steroids (i.e., prednisone, dexamethasone) or continuous use of topical steroid creams or ointments or ophthalmologic steroids. A history of occasional (but not continuous) use of steroid inhalers is allowed.
• Replacement doses of steroids for patients with adrenal insufficiency are allowed. Patients who discontinue use of these classes of medication for at least 2 weeks prior to initiation of study treatment are eligible if, in the judgment of the treating physician investigator, the patient is not likely to require resumption of treatment with these classes of drugs during the study. Exclusion from this study also includes patients with a history of symptomatic autoimmune disease (e.g., rheumatoid arthritis, systemic progressive sclerosis  scleroderma], systemic lupus erythematosus, Sjögren's syndrome, autoimmune vasculitis [e.g., Wegener’s Granulomatosis]); motor neuropathy considered of autoimmune origin (e.g., Guillain-Barre Syndrome and Myasthenia Gravis); other CNS autoimmune disease (e.g., Multiple sclerosis).
