An Open-Label Study to Investigate the Regional Brain Kinetics of the Positron Emission Tomography Ligand 11C-MK-3168 and the Blocking of the Retention of the Ligand in the Human Brain by JNJ-42165279

The purpose of the study is to measure the uptake, distribution, and clearance of 11C-MK-3168 by Positron Emission Tomography (PET) scan and to model the tissue specific kinetics of 11C-MK-3168 with the appropriate input function in human brain in Part A; to measure blocking of retention of 11C-MK-3168 at the estimated time to maximum plasma concentration after dosing (tmax) following each single oral doses of JNJ-42165279 and model the exposure/enzyme interaction of JNJ-42165279 in Part B; to measure the saturation of enzyme inhibition in the brain at steady state plasma concentrations of JNJ-42165279 (on Day 8) after 7 once-daily doses of JNJ-42165279 by conducting PET studies with 11C-MK-3168 at trough plasma concentrations on Day 2 in Part C.

AbstractInhibition of fatty acid amide hydrolase (FAAH) potentiates endocannabinoid activity and is hypothesized to have therapeutic potential for mood and anxiety disorders and pain. The clinical profile of JNJ‐42165279, an oral selective FAAH inhibitor, was assessed by investigating the pharmacokinetics, pharmacodynamics, safety, and binding to FAAH in the brain of healthy human volunteers. Concentrations of JNJ‐42165279 (plasma, cerebrospinal fluid (CSF), urine) and fatty acid amides (FAA; plasma, CSF), and FAAH activity in leukocytes was determined in a phase I multiple ascending dose study. A positron emission tomography study with the FAAH tracer [11C]MK3168 was conducted to determine brain FAAH occupancy after single and multiple doses of JNJ‐42165279. JNJ‐42165279 administration resulted in an increase in plasma and CSF FAA. Significant blocking of brain FAAH binding of [11C]MK3168 was observed after pretreatment with JNJ‐42165279. JNJ‐42165279 produces potent central and peripheral FAAH inhibition. Saturation of brain FAAH occupancy occurred with doses ≥10 mg of JNJ‐42165279. No safety concerns were identified.

We report herein the discovery of a fatty acid amide hydrolase (FAAH) positron emission tomography (PET) tracer. Starting from a pyrazole lead, medicinal chemistry efforts directed toward reducing lipophilicity led to the synthesis of a series of imidazole analogues. Compound 6 was chosen for further profiling due to its appropriate physical chemical properties and excellent FAAH inhibition potency across species. [(11)C]-6 (MK-3168) exhibited good brain uptake and FAAH-specific signal in rhesus monkeys and is a suitable PET tracer for imaging FAAH in the brain.
