Inclusion Criteria
- Patients with relapsed or refractory classical HL who have previously received
autologous stem cell transplant and/or allogeneic stem cell transplant. Patients must
have received prior autologous stem cell transplant at least 12 weeks (3 months)
before the first dose of ibrutinib and/or allogeneic stem cell transplant must have
been completed at least 6 months prior to the first dose of Ibrutinib. OR
- Patients with relapsed or refractory HL who have failed at least 2 lines of prior
therapy and are not eligible for autologous stem cell transplant due to:
- Inability to achieve a CR or PR prior to transplant
- Age or comorbid conditions
- Inability to collect stem cells
- Completion of any prior treatment with radiation, chemotherapy, biologics, and/or
other investigational agents at least 4 weeks prior to the first dose of ibrutinib.
Patients must have completed any prior immunotherapy (e.g., rituximab or PD-1
inhibition) or antibody drug conjugate therapy (e.g. brentuximab vedotin) at least 4
weeks prior to the first dose of ibrutinib in the absence of clear disease
progression.
- Prior treatment with at least 2 lines of therapy for HL including brentuximab vedotin.
In those patients who cannot receive brentuximab vedotin, treatment with 2 prior
therapeutic regimens is sufficient.

in minimum dimension by CT scan with contrast, as assessed by the site radiologist.
- Adequate hematologic function independent of transfusion and growth factor support for
at least 7 days prior to screening and randomization, with the exception of PEGylated
GCSF (pegfilgrastim) and darbopoeitin which require at least 14 days prior to
screening and randomization defined as:
- Absolute neutrophil count >750 cells/mm3 (0.75 x 109/L).
- Platelet count >50,000 cells/mm3 (50 x 109/L).

history-no menses for =1 year; OR history of hysterectomy; OR history of bilateral
tubal ligation; OR history of bilateral oophorectomy). Female subjects of childbearing
potential must have a negative serum pregnancy test upon study entry.
- Male and female subjects who agree to use highly effective methods of birth control
(e.g., condoms, implants, injectables, combined oral contraceptives, some intrauterine
devices [IUDs], sexual abstinence, or sterilized partner) during the period of therapy
and for 90 days after the last dose of study drug
- Sign (or their legally-acceptable representatives must sign) an informed consent
document indicating that they understand the purpose of and procedures required for
the study and are willing to participate in the study.

- Nodular lymphocyte predominant Hodgkin's Lymphoma subtype
- Concurrent therapy with other systemic anti-neoplastic or investigational agents

recurrence by treating physician.
- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence
of disease.
- Adequately treated carcinoma in situ without evidence of disease.
- Concurrent systemic immunosuppressant therapy (e.g., cyclosporine A, tacrolimus, etc.,
or chronic administration [>14 days] of >20 mg/day of prednisone) within 28 days of
the first dose of study drug.
- Vaccinated with live, attenuated vaccines within 4 weeks of first dose of study drug
- Recent infection requiring systemic treatment that was completed =14 days before the
first dose of study drug.
- Unresolved toxicities from prior anti-cancer therapy, defined as having not resolved

the levels dictated in the inclusion/exclusion criteria with the exception of
alopecia.
- Known bleeding disorders (e.g., von Willebrand's disease) or hemophilia.
- History of stroke or intracranial hemorrhage within 6 months prior to enrollment.
- Known history of human immunodeficiency virus (HIV) or active with hepatitis C virus
(HCV) or hepatitis B virus (HBV). Subjects who are positive for hepatitis B core

(PCR) result before enrollment. Those who are PCR positive will be excluded.
- Any uncontrolled active systemic infection

- Any life-threatening illness, medical condition, or organ system dysfunction that, in
the investigator's opinion, could compromise the subject's safety or put the study
outcomes at undue risk.

Association Functional Classification; or a history of myocardial infarction, unstable
angina, or acute coronary syndrome within 6 months prior to randomization
