Safety Study of HBI-8000 in Japanese Patients With Non Hodgkin's Lymphoma

Exclusion Criteria

• •1. Patients with current, previous, or clinically suspected invasion of the central nervous system (CNS)
• •2. Organ transplant recipients
• •3. Allogeneic stem cell transplant recipients
• •4. Previous extensive radiotherapy involving ≥30% of hematopoietic bone marrow, excluding patients who have had total body irradiation as part of a conditioning regimen for ASCT
• •5. Patients with an electrocardiogram (ECG) finding at screening of QT interval corrected for heart rate using Fridericia's method (QTcF) prolongation \>450 ms in male patients and \>470 ms in female patients, ventricular tachycardia, ventricular fibrillation, second- or third-degree heart block, unstable angina, coronary angioplasty or stenting, myocardial infarction, chronic congestive heart failure (New York Heart Association Class III or IV) within 6 months of starting the study drug, any cardiomyopathy, or long QT syndrome
• •6. Any condition including the presence of laboratory abnormalities, which, as judged by the investigator, places the patient at unacceptable risk if he/she were to participate in the study. Examples of such medical conditions are, but are not limited to, as follows:
• •• Uncontrolled diabetes mellitus (e.g., glycosylated hemoglobin \[HbA1c\] \>8%), as judged by the investigator
• •7. Patients who have had any of the following abnormal measurements at screening performed within 2 weeks (14 days) prior to the start of study drug administration:
• •* Hemoglobin: \<8 g/dL
• •* Neutrophil count: \<1,200/µL
• •* Platelet count: \<75,000/µL
• •* Serum aspartate aminotransferase (AST) or alanine aminotransferase (ALT): \>3 x the upper limit of normal (ULN)
• •* Bilirubin level: \>1.5 x ULN
• •* Creatinine clearance: \<50 mL/min via Cockcroft-Gault formula ; proteinuria \> Grade 2
• •* Plasma troponin I (or troponin T): \>ULN
• •* Prothrombin time or activated partial thromboplastin time: \>1.25 x ULN
• •* Potassium, corrected calcium , or magnesium levels outside normal limits
• •8. Any cardiac arrhythmia requiring anti-arrhythmic medication
• •9. Patients with a history of seizures
• •10. Patients with known hypersensitivity to histone deacetylase (HDAC) inhibitors or any of the components of the HBI-8000 tablets
• •11. Patients with a history or complication of malignant tumors, unless the patients have been free of the disease for 5 years or longer, except the following, if successfully treated, in which case they are not excluded:
• •* Basal cell carcinoma of the skin
• •* Squamous cell carcinoma of the skin
• •* Cervical carcinoma in situ
• •* Carcinoma in situ of the breast
• •* An incidental histological finding of prostate carcinoma (TNM stage T1a or T1b)
• •* Early-stage gastric cancer treated with endoscopic mucosal resection or endoscopic submucosal dissection
• •12. Patients with uncontrolled inter-current infection
• •13. Patients with active clinically significant bleeding or recently occurred thrombotic diseases, including patients who are at a high risk for a thromboembolic event and are not willing to take venous thromboembolic prophylaxis
• •14. Women who are pregnant, women who are not willing to stop breastfeeding during study period and for 10 days after the last dose of study drug, women of child bearing potential, or men with a sexual partner of child bearing potential who are not willing to use double-barrier method during study period and at least 3 months (for men) or at least 1 month (for women) after the last dose of study drug. Double-barrier method is defined as a combination of 2 effective contraceptive methods, such as condom or condom containing spermicide in combination with a diaphragm, oral contraceptive, or intrauterine device.
• •Note: Female subjects will be considered to be a woman of childbearing potential unless having undergone permanent contraception or postmenopausal. Postmenopausal is defined as at least 12 months without menses with no other medical reasons (i.e., chemical menopause because of treatment with anti-malignant tumor agents).
• •15. Seropositivity for the human immunodeficiency virus (HIV) antibody
• •16. Hepatitis B surface antigen-positive, or hepatitis C virus antibody positive. In case hepatitis B core antibody and/or hepatitis B surface antibody is positive even if hepatitis B surface antigen negative, a hepatitis B virus deoxyribonucleic acid (DNA) test \[real-time polymerase chain reaction (PCR\]) measurement\] should be performed and if positive, the patient should be excluded
• •17. Patients who were in other experimental clinical studies with investigational agents within 30 days before the start of study drug administration (12 weeks for any investigational antibody therapy or investigational ASCT), or in current clinical studies with investigational agents
• •18. Patients with a history of drug abuse or long-term excessive alcohol consumption which could affect study result assessment
• •19. Patients considered by the investigator to be unsuitable for the study because of any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the patient from participating in the study, or because of any condition that confounds the ability to interpret data from the study
