The purpose of this study is to determine the safety, pharmacokinetics, and preliminary efficacy information of JNJ-40346527 in patients with relapsed or refractory Hodgkin lymphoma.

This is an open-label (individuals will know the identity of study treatments), dose-escalation study to evaluate the clinical efficacy, safety, and pharmacokinetics (PK; study of what the body does to a drug) of JNJ-40346527. Up to 38 subjects could be enrolled in the Phase 1 portion of the study and up to 30 subjects could be enrolled in the Phase 2 portion of the study (although planned, the study did not move forward to the Phase 2 portion). During the Phase 1 portion of the study, dose escalation of JNJ-40346527 will start at 150 mg (Cohort 1) once daily up to the maximum tolerated dose (MTD) or the highest planned dose (600 mg once daily); twice daily dosing may also be performed if deemed necessary. A Study Evaluation Team (SET) will review all available data after 1 cycle (21 days) of treatment for each cohort before any additional dose escalation occurs and will also determine the recommended Phase 2 dose for the expansion cohort. This study will consist of 3 periods: a screening period (from signing of informed consent until immediately before dosing), an open-label treatment period (from the first dose of study drug until the end-of-treatment visit), and a follow-up period (after the end-of-treatment visit). All patients will participate in the screening and treatment period. Patients will be administered JNJ-40346527 continuously until disease progression, or unacceptable toxicity (based on investigator assessment). The National Cancer Institute-Common Terminology Criteria for Adverse Events will be used to grade toxicity throughout the study. Disease response will be assessed according to the Revised Response Criteria for Malignant Lymphoma. Treatment will continue until disease progression or unacceptable toxicity (based on investigator assessment) occurs. Only patients who discontinue study drug before disease progression or discontinue due to treatment-related Grade 3 or higher toxicity will continue in the follow-up period. Serial PK samples will be collected in Cycle 1 as detailed in the protocol. Safety will be monitored throughout the study.

Inclusion Criteria:

- Patients with histopathologically confirmed initial diagnosis of Hodgkin lymphoma and who have disease that has relapsed or is refractory that is progressing or active and requires treatment after at least 1 appropriate therapy

Exclusion Criteria:

• Known brain metastases or leptomeningeal disease
• Other malignancy within past 5 years
• Has any condition that, in the opinion of the investigator, would make study participation not be in the best interest (eg, compromise the well-being) of the patient or that could prevent, limit, or confound the protocol-specified assessments
• QTc prolongation at screening or other factors that increase the risk of QT prolongation such as diagnosis or family history of long-QT syndrome, diagnosed or suspected congenital long QT syndrome, or concomitant use of medication that can prolong the QT interval
• Taking CYP3A4 substrate drugs with a narrow therapeutic index (eg, alfentanil, astemizole, sirolimus, tacrolimus, terfenadine)
