benefit from PCI 24781 PO for at least 6 months and want to continue receiving study drug.

Subjects enrolled in this study will receive PCI-24781 at the schedule and dosage from their
prior protocol. Treatment may be continued as long as there is no evidence of progressive

study protocol including swallowing capsules without difficulty

5. 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. A life-threatening illness, medical condition or organ system dysfunction which, in
the investigator's opinion, could compromise the subject's safety, interfere with the
absorption or metabolism of oral PCI-24781, or put the study outcomes at undue risk

2. Significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias,
congestive heart failure, or myocardial infarction within 6 months of screening, or
any Class 3 or 4 cardiac disease as defined by the New York Heart Association
Functional Classification

prednisone > 20 mg/day) or experimental therapy (other than PCI-24781 PO) within 4
weeks before first dose of study drug

5. Concomitant use of medicines known to cause QT prolongation or torsades de points
(see Appendix 2)

6. Central nervous system involvement by lymphoma

7. Known history of Human Immunodeficiency Virus (HIV) or active infection with
Hepatitis C Virus (HCV) or Hepatitis B Virus (HBV) or any uncontrolled active
systemic infection

8. Creatinine > 1.5 x institutional upper limit of normal (ULN); total bilirubin > 1.5 x
