A Dose Escalation Study of Selinexor (KPT-330), a Selective Inhibitor of Nuclear Export, and Ibrutinib, a Bruton's Tyrosine Kinase Inhibitor, in Patients With Relapsed and Refractory Chronic Lymphocytic Leukemia or Aggressive Non-Hodgkin Lymphoma

This phase I trial studies the side effects and best dose of selinexor when given together
with ibrutinib in treating patients with chronic lymphocytic leukemia or aggressive
non-Hodgkin lymphoma that has returned after a period of improvement or does not respond to
treatment. Drugs used in chemotherapy, such as selinexor, 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. Ibrutinib may stop the growth of cancer cells by blocking some
of the enzymes needed for cell growth. Giving selinexor together with ibrutinib may be a
better treatment for chronic lymphocytic leukemia or aggressive non-Hodgkin lymphoma.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose for the combination of selinexor and ibrutinib in
patients with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic
leukemia(SLL)/B-cell prolymphocytic leukemia (PLL) or aggressive non-Hodgkin lymphoma (NHL).

SECONDARY OBJECTIVES:

I. To characterize the safety and tolerability of the combination of selinexor and ibrutinib
in patients with relapsed or refractory CLL/SLL/PLL or aggressive NHL.

II. To characterize the pharmacokinetic (PK) properties of the combination of selinexor and
ibrutinib in patients with relapsed or refractory CLL/SLL/PLL or aggressive NHL.

III. To obtain preliminary evidence on efficacy of the combination of selinexor and ibrutinib
in patients with relapsed or refractory CLL/SLL/PLL or aggressive NHL.

IV. To obtain preliminary evidence of response in CLL/SLL/PLL and diffuse large B-cell
lymphoma (DLBCL) patients receiving the combination of selinexor and ibrutinib as related to
CLL/SLL/PLL karyotype and immunoglobulin variable heavy chain (IgVH) mutational status and
DLBCL subtype, respectively.

V. To evaluate the inhibition of the B-cell receptor signaling pathway in patients with
relapsed or refractory CLL/SLL/PLL who receive the combination of selinexor and ibrutinib.

VI. To evaluate the change in localization of tumor suppressor and growth regulation proteins
in patients with relapsed or refractory CLL/SLL/PLL following treatment with selinexor in
general and as related to response.

VII. To preliminarily assess potential causes for primary and secondary resistance to
selinexor and ibrutinib.

VIII. To measure intracellular levels of selinexor and metabolites in peripheral blood
mononuclear cells and to identify how this relates to pharmacodynamics effects and clinical
outcomes.

OUTLINE: This is a dose-escalation study of selinexor.

Patients receive ibrutinib orally (PO) on days 8-28 of course 1 and on days 1-28 on
subsequent courses and selinexor PO twice daily (BID) weekly on day 1 or bi-weekly on days 1
and 3. Courses repeat every 28 days in the absence of disease progression or unacceptable
toxicity.

After completion of study treatment, patients are followed up at 4 weeks and then every 6
months thereafter.

Inclusion Criteria:

- A histologically confirmed diagnosis of CLL according the International Workshop on
CLL/SLL/B-cell PLL or variant of these (IWCLL or World Health Organization [WHO]
Criteria) and meet criteria for treatment or have need for cytoreduction for stem cell
transplantation or alternative cell therapy; OR

- A histologically confirmed diagnosis of mantle cell lymphoma (MCL) or diffuse large
B-cell lymphoma (DLBCL) de novo or in the setting of transformation from an indolent
lymphoma (including DLBCL not otherwise specified) according to the World Health
Organization criteria for diagnosis of NHL; AND

- Patients must have received at least one prior therapy for CLL or NHL, need additional
treatment, and meet criteria for relapsed or refractory disease; they may not be a
candidate for curative therapy; relapsed disease is defined as a patient who
previously achieved a complete remission (CR) or a partial remission (PR), but after a
period of six or more months demonstrates evidence of disease progression; refractory
disease is defined as progression within six months of the last anti-leukemic or
anti-lymphoma therapy, or any response less than a CR or PR

- Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of
=< 2

- Patients with NHL must have objective, documented evidence of disease prior to study
entry

- Platelet count >= 50,000/mm^3 in the absence of bone marrow involvement; patients with
bone marrow involvement only require a platelet count of 30,000/mm^3

- Absolute neutrophil count >= 1000/mm^3 in the absence of bone marrow involvement

- Creatinine clearance (as calculated by Cockroft Gault equation = [140-age] * mass
[kg]/[72 * creatinine mg/dL) >= 30mL/min

- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) < 2.5 times upper
limit of normal (ULN)

- Total bilirubin =< 2.0 x ULN

reproduction must agree to use an effective contraceptive method during the course of
the study and for 2 months following the completion of their last treatment

gonadotropin (HCG) pregnancy test result within 3 days of first study dose; female
patients who are surgically sterilized or who are > 45 years old and have not
experienced menses for > 2 years may have beta-HCG pregnancy test waived

- Patients who are hepatitis B polymerase chain reaction (PCR) negative who have a
recent (< 6 month) history of intravenous immunoglobulin (IVIG) therapy are eligible;
patients with a history of hepatitis B (surface antigen or core antibody positive and
PCR positive) must take lamivudine or equivalent drug during study therapy and for one
year after completion of all therapy; patients on IVIG who are core antibody positive
but PCR negative are not mandated to take prophylaxis
