A Safety and Pharmacokinetics Study of CNTO 3157 in Healthy Japanese and Caucasian Participants

Phase 1CompletedNCT02008279

Janssen Research & Development, LLC40 enrolled

Overview

The purpose of this study is to find out if different doses of CNTO 3157 are well tolerated in both Japanese and Caucasian men as well as to understand how the body absorbs and removes the study drug after being injected or infused into the body.

This will be a randomized (the treatment is assigned by chance), double-blind (neither the participants nor study staff know the identity of the assigned treatment), placebo-controlled study (one of the study medications is inactive) to investigate the pharmacokinetics (ie, how the body absorbs and removes the study drug) and safety of subcutaneous (administered under the skin) (SC) CNTO 3157 (a drug currently being investigated for the treatment of asthma) in both Japanese and Caucasian men. Additionally, an open-label cohort (where participants and study staff know the identity of the assigned treatment) in Caucasian men will investigate the pharmacokinetics and safety of a single intravenous (into a vein) (IV) infusion. The study will consist of 3 phases: a screening phase, a treatment phase (comprising 2 days and 1 night at the study center) and a follow-up period (comprising approximately 11 visits to the study center). During the double-blind SC treatment period, participants will be randomly assigned to 1 of 3 treatment groups: group 1 will receive a single SC injection of 100 mg CNTO 3157 or placebo; group 2 will receive 2 SC injections of CNTO 3157 (making a total dose of 300mg) or placebo; group 3 will receive 4 SC injections of CNTO 3157 (making a total dose of 600 mg) or placebo. Group 4 (open-label cohort) will receive a single IV infusion of 300 mg CNTO 3157. Participants will be enrolled in each SC dose group sequentially from the lower to higher dose level. The study sponsor and the study doctor will review the test results (in terms of safety and tolerability) for each group before dosing participants in the next treatment group; this review will be carried out in a blinded manner. An equal number of Japanese and Caucasian participants will be assigned to the SC treatment groups forming 2 subgroups within each group (groups 1A, 1B, 2A, 2B, 3A and 3B). Within each SC treatment group, 10 participants will be randomly assigned in a 4 to 1 ratio to receive CNTO 3157 or placebo. Only Caucasian participants will be enrolled in the IV treatment group (group 4). For each treatment group, blood and urine samples will be taken at various time points during the study. Each participant will take part in the study for approximately 85 days. Participant safety will be monitored throughout the study.

Inclusion Criteria: * Participants must have a screening body weight in the range of 50 kg to 100 kg, inclusive, and a screening body mass index of 18.5 kg/m2 to 30 kg/m2, inclusive * Participants must be: of Japanese descent whose parents and maternal and paternal grandparents are Japanese, as determined by participant's verbal report; Japanese participants must have valid government issued identification; Japanese participants must have resided outside of Japan for \<= 5 years; or must be of non-Hispanic Caucasian descent whose parents are Caucasian, as determined by participant's verbal report * Participants must have been exposed to herpes simplex-type 1 virus (HSV-1) as documented by a positive serology test result for HSV-1 performed at screening, but have no signs or symptoms suggestive of an active HSV-1 infection and are not receiving prescription treatment or prophylaxis for HSV-1 Exclusion Criteria: * Participant has or has had a clinically significant (viral, bacterial or parasitic) infection, a prior history of recurrent serious infection (eg, sepsis, pneumonia or pyelonephritis) or be immunosuppressed or have been hospitalized or received IV antibiotics for an infection during the 2 months prior to screening * Participant is infected with human immunodeficiency virus or tests positive for hepatitis B virus infection or has antibodies to hepatitis C virus at screening * Participant has received any live or attenuated virus or bacterial vaccinations within 3 months prior to study agent administration or is expected to receive any live virus or bacterial vaccinations during the study or up to 6 months after administration of the study agent * Participant has had major surgery, (eg, requiring general anesthesia) within 12 weeks before screening, or will not have fully recovered from surgery, or has surgery planned during the time the participant is expected to participate in the study OR has had a major illness or hospitalization within 1 month prior to study agent administration * Participant has a history of, or currently active illness/disorder, considered to be clinically significant by the Investigator or any other illness/disorder that the Investigator considers should exclude the participant from the study or that could interfere with the interpretation of the study results

Outcomes

Primary Outcomes

Frequency of adverse events

The frequency of adverse events will be used to assess the safety and tolerability of CNTO 3157.

Time frame: Up to Day 57

Serum concentrations of CNTO 3157 in Caucasian and Japanese participants following single subcutaneous doses of 100 mg, 300 mg, and 600 mg

Serum concentrations of CNTO 3157 will be used to determine pharmacokinetic parameters (measurements that explore what the body does to the drug).

Time frame: Up to Day 57

Titer (concentration) of antibodies to CNTO 3157 in Caucasian and Japanese participants following single subcutaneous doses of 100 mg, 300 mg, and 600 mg

Serum samples will be screened for antibodies binding to CNTO 3157 providing an indication of the ability of CNTO 3157 to cause an immune response.

Time frame: Up to Day 57

Secondary Outcomes

Serum concentrations of CNTO 3157 in Caucasian participants following a single intravenous infusion of 300 mg

Serum concentrations of CNTO 3157 will be used to determine pharmacokinetic parameters (measurements that explore what the body does to the drug).

Time frame: Up to Day 57

Titer (concentration) of antibodies to CNTO 3157 in Caucasian participants following a single intravenous infusion of 300 mg
