Pharmacokinetics (PK) and Pharmacodynamics (PD) Study of Single and Multiple Ascending Doses of JNJ-41443532 in Healthy Male Participants

2014-08-27 03:14:28 | BioPortfolio


The purpose of this study is to investigate the safety, tolerability, food effect as well as the pharmacokinetics (how the drug is absorbed in the body, how it is distributed within the body and how it is removed from the body over time) and pharmacodynamics (the effects of the drug) of single and multiple ascending doses of JNJ-41443532 in healthy male participants.


This is a randomized (study drug assigned by chance), double-blind (neither physician nor participant knows the name of the assigned drug), placebo-controlled, single and multiple ascending dose study conducted at a single study center. The study has 4 parts. Part 1 is a randomized, double-blind, alternating panel, single ascending oral dose study. Two alternating treatment panels (A and B) each with nine healthy male participants will be studied with successively increasing dose levels. Part 2 is a randomized, open-label (all people involved know the identity of the intervention), 2-period crossover study to evaluate what the effect of administering JNJ- 41443532 with food (i.e. standard high fat breakfast meal) relative to administration in the fasted state will have on pharmacokinetics/blood levels of JNJ-41443532. Part 3 is a randomized, double-blind, single oral dose study in obese, otherwise healthy male participants. Part 4 is a double-blind, randomized, placebo-controlled multiple ascending dose study in up to 5 sequential treatment groups of healthy male participants. Safety assessments include monitoring of adverse events, and evaluation of lab results, cardiac parameters, vital signs, and physical exams. In Parts 1, 2, and 3 participants receive study medication (JNJ-41443532 or placebo) orally on Day 1 after an overnight fast of at least 10 hours; planned doses are 25 to 1500 mg. In Part 4, participants receive study medication (JNJ-41443532 or placebo) orally each day for 10 consecutive days after an overnight fast of at least 10 hours; planned doses are 100 to 1000 mg.

Medical and Biotech [MESH] Definitions

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.
