Acalabrutinib in Combination With R-ICE For Relapsed or Refractory Lymphoma
Acalabrutinib in Combination With R-ICE For Relapsed or Refractory Lymphoma
The purpose of this study is to test a combination treatment of acalabrutunib when given
 together with rituximab-ifosfamide-carboplatin-etoposide (R-ICE) to evaluate if it will be
 able to improve durable responses and cure some patients.
Inclusion Criteria:

 1. Men and women ≥ 18 years of age.

 2. Patients must have histologic confirmation of relapsed or refractory lymphoma.

 3. Baseline FDG-PET scans must demonstrate positive lesions compatible with CT defined
 anatomical tumor sites.

 a) CT scan showing at least:

 -  i. 2 or more clearly demarcated lesions/nodes with a long axis >1.5cm and short
 axis ≥ 1.0cm, or

 -  ii. 1 clearly demarcated lesion/node with a long axis >2.0cm and short axis
 ≥1.0cm.

 4. Patient must have been previously treated for B cell non-Hodgkin lymphoma with any of
 the allowable below:

 1. First-line treatment with rituximab and an anthracycline-based chemotherapy.

 2. Monotherapy rituximab, dosed prior to first-line rituximab combined with
 anthracycline containing chemotherapy, or as maintenance therapy.

 3. Radiotherapy as part of the first-line treatment plan including anthracycline and
 rituximab.

 5. Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2.

 6. Life expectancy of greater than 6 weeks.

 7. Patients must have normal organ and marrow function as defined below,

 1. absolute neutrophil count ≥ 1000/microliters (mcL) (unless due to lymphoma
 involvement of the bone marrow),

 2. platelets ≥75,000/mcL (unless due to lymphoma involvement of the bone marrow),

 3. total bilirubin <1.5 x within normal institutional limits (unless due to lymphoma
 involvement of liver or a known history of Gilbert's disease),

 4. Aspartate transaminase (AST) (SGOT)/Alanine transaminase (ALT) (SGPT) ≤ 2.5 ×
 institutional upper limit of normal (unless due to lymphoma involvement of
 liver),

 5. creatinine within normal institutional limits, or

 6. creatinine clearance ≥40 mL/min/1.73 m2 for patients with creatinine levels above
 institutional normal. (unless due to lymphoma).

 8. Major surgical procedure within 28 days of first dose of study drug. If a subject had
 major surgery, they must have recovered adequately from any toxicity and/or
 complications from the intervention before the first dose of study drug.

 9. Women who are sexually active and can bear children must agree to use highly effective
 forms of contraception during the study and for 90 days after the last dose of
 acalabrutinib + R-ICE.

 10. Men who are sexually active and can beget children must agree to use highly effective
 forms of contraception during the study and for 90 days after the last dose of
 acalabrutinib + R-ICE.

 11. Men must agree to refrain from sperm donation during the study and for 90 days after
 the last dose of study drug.

 12. Willing and able to participate in all required evaluations and procedures in this
 study protocol including swallowing capsules without difficulty.

 13. Ability to understand the purpose and risks of the study and provide signed and dated
 informed consent and authorization to use protected health information (in accordance
 with national and local subject privacy regulations).

 Exclusion Criteria:

 1. Germinal-center cell-of-origin DLBCL.

 2. Patients who have had chemotherapy or radiotherapy < 21 days prior to first
 administration of study treatment or those who have not recovered from adverse events
 due to agents administered more than 4 weeks earlier.

 3. Patients who are receiving any other investigational agents.

 4. Patients with known central nervous system involvement of lymphoma.

 5. History of allergic reactions attributed to compounds of similar chemical or biologic
 composition to acalabrutinib or R-ICE with the exception of first-infusion reaction to
 rituximab.

 6. Uncontrolled intercurrent illness including, but not limited to, ongoing or active
 infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
 arrhythmia, or psychiatric illness/social situations that would limit compliance with
 study requirements. Recent infections requiring systemic treatment need to have
 completed therapy > 7 days before the first dose of study drug.

 7. Pregnant women are excluded from this study because an acalabrutinib R-ICE is a
 chemotherapy program 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 acalabrutinib R-ICE, breastfeeding should be
 discontinued if the mother is treated with acalabrutinib R-ICE.

 8. HIV-positive patients on combination antiretroviral therapy are eligible, unless the
 patient's CD4 count is below the institutional lower limit of normal, or the patient
 is taking prohibited CYP3A4/5 strong inhibitors or inducers.

 9. Patients may not have received any anti-cancer therapy for their primary rel/ref DLBCL
 with the exception of palliative radiation therapy (RT).

 10. Uncontrolled Autoimmune Hemolytic Anemia or immune thrombocytopenia purpura (ITP)
 resulting in (or as evidenced by) declining platelet or Hgb levels within the 4 weeks
 prior to first dose of study drug.

 11. Presence of transfusion-dependent thrombocytopenia.

 12. Prior exposure to a Bruton's tyrosine kinase (BTK) inhibitor.

 13. History of prior malignancy, with the exception of the following:

 1. Malignancy treated with curative intent felt to be at low risk for recurrence by
 treating physician,

 2. Adequately treated non-melanomatous skin cancer or lentigo maligna melanoma

 positive for hepatitis B core antibody, hepatitis B surface antigen (HBsAg), or
 hepatitis C antibody will need a negative polymerase chain reaction (PCR) prior to
 enrollment. (PCR positive patients will be excluded.) Hepatitis C antibody positive
 patients are eligible if PCR is negative. Hepatitis B core antibody (+) patients

 reactivation prophylaxis.

 17. History of stroke or intracranial hemorrhage within 6 months prior to enrollment.

 18. Current life-threatening illness, medical condition, or organ system dysfunction
