| Phase 1 |
Detailed Description
Phase 1, open-label, non-randomized, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of HBI-8000 administered orally. Patients must be hospitalized as per guidance of the treating investigator throughout Cycle 1. Patients will receive HBI 8000 twice weekly (BIW) (after breakfast), in 28 day treatment cycles.
Patients will be enrolled in cohorts of 3 patients. The first cohort of 3 patients will receive 30 mg BIW. Decisions regarding cohort escalation will be based upon the clinical experience in Cycle 1 (first 28 days) only. For a given cohort, if 1 patient enrolled in the cohort experiences a dose limiting toxicity (DLT) within 28 days of the first dose, the cohort will be expanded to 6 patients.

Outcome Measures
Primary Outcome Measures
- Maximum tolerated dose (MTD) of HBI-8000 in adult Japanese patients with non Hodgkin's lymphoma (NHL) for whom no other standard therapy is suitable based on the frequency of dose-limiting toxicities (DLTs) which occur within 28 days. [28 days]
Secondary Outcome Measures
- Pharmacokinetic parameter: area under the plasma concentration-time curve (AUC) measurement at 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 6, 12, 24, 48, and 72 hours. [28 days]
Plasma concentration of HBI-8000 will be measured following single dose (Days 1-4) and multiple dose (Days 25-28) administration
- Pharmacokinetic parameter: maximum observed plasma concentration (Cmax) measurement at 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 6, 12, 24, 48, and 72 hours. [28 days]
Plasma concentration of HBI-8000 will be measured following single dose (Days 1-4) and multiple dose (Days 25-28) administration
- Pharmacokinetic parameter: time of maximum observed plasma concentration (Tmax) at 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 6, 12, 24, 48, and 72 hours. [28 days]
Plasma concentration of HBI-8000 will be measured following single dose (Days 1-4) and multiple dose (Days 25-28) administration
- Pharmacokinetic parameter: apparent terminal half-life (T1/2) at 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 6, 12, 24, 48, and 72 hours. [28 days]
Plasma concentration of HBI-8000 will be measured following single dose (Days 1-4) and multiple dose (Days 25-28) administration
- Anti-tumor activity of HBI-8000 by overall response status based on Cheson's response criteria for NHL and Japan Clinical Oncology Group (JCOG) response criteria for Adult T-Cell Lymphoma (ATL) [Through study completion, an average of 24 weeks.]
- Safety of HBI-8000 in Japanese patients with NHL for whom no other standard therapy is suitable with incidence and severity of adverse events graded according to the NCI-CTCAE version 4.03 [Through study completion, an average of 24 weeks.]
