JNJ-10450232 (NTM-006), A novel non-opioid with structural similarities to acetaminophen, produces relatively long-lasting analgesia after a single dose in patients undergoing 3rd molar extraction

Abstract

JNJ-10450232 (NTM-006) is a non-opioid, non-NSAID analgesic and antipyretic compound with structural similarity to acetaminophen. Preclinical models show comparable analgesia relative to acetaminophen and no evidence of hepatotoxicity associated with overdose. Moreover, it was safe and generally well tolerated in a First-in-Human Study. This single-dose, single-center, inpatient, randomized, double-blind study in moderate-to-severe acute pain following third molar extraction compared efficacy and safety of 250 mg and 1000 mg JNJ-10450232 (NTM-006), 1000 mg acetaminophen, and placebo during the 24 h following administration. While onset of action of 1000 mg JNJ-10450232 (NTM-006) was relatively slower compared with acetaminophen, its duration of action was sustained up to 24 h being superior beginning 7 h after administration. No clinically important differences among treatment groups in nature or severity of adverse events were observed and no serious adverse events were reported. Increased bilirubin, potentially due to UGT1A1 inhibition and ingestion of blood from oral surgery, was the most commonly reported adverse event and the only event reported by ≥ 5% of subjects across treatment groups. These data support further evaluation of JNJ-10450232 (NTM-006) for the treatment of moderate-to-severe pain. ClinicalTrials.gov IDNCT02209181.
