About

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) after single dose and multiple dose administrations of JNJ-40411813 in Japanese healthy adult male participants.

Enrollment: 39 patients

Sex: Male

Ages: 20 to 55 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Be a Japanese man
• Be healthy on the basis of clinical laboratory tests performed at screening. If the results of the serum chemistry panel, hematology, or urinalysis are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant. This determination must be recorded in the participant's source documents and initialed by the investigator
• Blood pressure (after the participant supine for 5 minutes) between 90 and 140 millimeter of Mercury (mmHg) systolic, inclusive, and no higher than 90 mmHg diastolic. If blood pressure is out of range, up to 2 repeated assessments are permitted
• During the study and for a minimum of 1 spermatogenesis cycle (defined as approximately 90 days) after receiving the last dose of study intervention, a participant must wear a condom when engaging in any activity that allows for passage of ejaculate to another person. Male participants should also be advised of the benefit for a female partner to use a highly effective method of contraception as condom may break or leak. Recommended highly effective methods of contraception in this study for female partners of male participants to use in addition to the male participant wearing a condom during include: a) oral hormonal contraception, b) intrauterine device, c) intrauterine hormone-releasing system, and d) bilateral tubal occlusion
• A participant must agree not to donate sperm for the purpose of reproduction during the study and for a minimum 90 days after receiving the last dose of study intervention

Exclusion criteria

• History of or current clinically significant medical illness including (but not limited to) cardiac arrhythmias or other cardiac disease, hematologic disease, coagulation disorders (including any abnormal bleeding or blood dyscrasias), lipid abnormalities, significant pulmonary disease, including bronchospastic respiratory disease, diabetes mellitus, hepatic or renal insufficiency, thyroid disease, neurologic or psychiatric disease, infection or any other illness that the investigator considers should exclude the participant or that could interfere with the interpretation of the study results
• Clinically significant abnormal values for hematology, clinical chemistry, or urinalysis at screening as deemed appropriate by the investigator
• Clinically significant abnormal physical examination, vital signs, or 12 lead electrocardiogram (ECG) at screening as deemed appropriate by the investigator
• Known allergies, hypersensitivity, or intolerance to JNJ-40411813 or its excipients
• Test positive for human immunodeficiency virus (HIV) antigen/antibodies, hepatitis A antibody immunoglobulin M (IgM), syphilis, hepatitis B surface antigen (HbsAg) or hepatitis C virus (HCV) antibodies at screening
