Trial Information

A Phase 1b, Multi-center, Open Label, Study to Determine the Safety and Activity of CC-292 in Combination With Rituximab in Subjects With Relapsed or Refractory Chronic Lymphocytic Leukemia / Small Lymphocytic Lymphoma.

This dose finding study uses a 3 + 3 dose escalation and expansion design to establish the
recommended Phase 2 dose (RP2D). Treatment will consist 28 day treatment cycles with a
single Rituximab infusion per cycle for 6 cycles and twice daily (days 1-28) administration
of CC-292 with a starting dose cohort of 375mg twice a day. Following safety review of the
data from the initial cohort and confirmation that the initial dose is tolerable, the next
dose level will be enrolled with a once per cycle Rituximab infusion for 6 cycles and twice
daily CC-292 at 500 mg.

Determination of the maximum tolerated dose and/or optimal biologic effect will be used to
establish a dose for evaluation in an expansion cohort of 24 subjects. Evaluation of the
data for subjects in the expansion cohorts will result in establishment of a RP2D.

Inclusion Criteria:

1. Male and female subjects 18 years of age and older at the time of signing the
informed consent document.

2. Understand and voluntarily sign an informed consent document (ICD) prior to any study
related assessments/procedures being conducted.

disease following last prior treatment.

1. Refractory is defined as CLL/SLL that does not achieve at least a partial
response (PR) to therapy or that progresses within 6 months of treatment.
Relapsed CLL/SLL refers to disease that progresses after ≥ 6 months in subjects
who had achieved a PR or complete response (CR) to therapy.

9. Females of childbearing potential (FCBP)must have a negative medically supervised
pregnancy test prior to starting of study therapy.

10. Male subjects must:

1. Agree to use a condom during sexual contact with a FCBP, even if they have had a
vasectomy, throughout study drug treatment, during any dose interruption and for
28 days after end of study therapy.

2. Agree to not donate semen during study drug treatment and for 28 days after end
of study drug treatment.

11. Ability to swallow oral capsules without difficulty.

12. Have an echocardiogram or multigated acquisition scan of the heart demonstrating left
ventricular ejection fraction (LVEF) ≥ 50% or the institution's lower limit of

13. Have recovered from adverse, toxic effects of prior therapies to Grade ≤ 1 National
Cancer Institute Common Terminology Criteria for Adverse Events (NCI/CTCAE) version
4.03 except for alopecia and peripheral neuropathy. This requirement will be
subordinate to specific clinical and laboratory criteria that are otherwise
specifically addressed in these inclusion/exclusion criteria.

Exclusion Criteria:

1. Any significant medical condition, laboratory abnormality, or psychiatric illness
that would prevent the subject from participating in the study.

2. Any condition including the presence of laboratory abnormalities, which places the
subject at unacceptable risk if he/she were to participate in the study.

3. Any condition that confounds the ability to interpret data from the study.

4. Autologous stem cell transplant within 3 months of screening date.

5. Uncontrolled intercurrent illness including, but not limited to:

1. Ongoing or active infection requiring parenteral antibiotics.

2. Uncontrolled diabetes mellitus as defined by the investigator.

3. Chronic symptomatic congestive heart failure (Class III or IV of the New York
Heart. Association Classification for Heart Disease; AppendixG).

4. Unstable angina pectoris, angioplasty, stenting, or myocardial infarction within
6 months of signing the ICD.

5. Clinically significant cardiac arrhythmia that is symptomatic or requires
treatment, or asymptomatic sustained ventricular tachycardia. Subjects with
controlled atrial fibrillation that is asymptomatic are eligible.

6. Pregnant or lactating females.

7. Prior history of malignancies, unless the subject has been free of the disease for ≥
3 years of signing the informed consent. Exceptions to the ≥ 3 year time limit
include history of the following:

1. Basal cell carcinoma of the skin.

2. Squamous cell carcinoma of the skin.

3. Carcinoma in situ of the cervix.

4. Carcinoma in situ of the breast.

5. Carcinoma in situ of the bladder.

6. Incidental histologic finding of prostate cancer (TNM stage of T1a or T1b). (The
TNM staging system is based on the extent of the tumor (T), whether cancer cells
have spread to nearby (regional) lymph nodes (N), and whether distant (to other
parts of the body) metastasis (M) has occurred).

8. Known seropositivity for or history of active viral infection with Human
Immunodeficiency Virus (HIV).

9. Seropositive for or active viral infection with Hepatitis B virus (HBV):

1. HBV surface antigen positive.

antibody positive and detectable viral deoxyribonucleic acid (DNA).

Note: Subjects who are HBV surface antigen negative and viral DNA negative are

3. Subjects who had HBV but have received an antiviral treatment and show no
detectable viral DNA within 6 months of signing the ICD are eligible.

4. Subjects who exhibit the classical vaccination profile of HBV surface antibody
positive, HBV core antibody negative, and HBV surface antigen negative are

these exclusionary laboratory values.
