Conditions: Pain
Keywords: dental pain post-surgical dental pain
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 269
Healthy volunteers: no

Brief summary:
To assess the safety and effectiveness one dose of a new pain reliever medicine (JNJ-10450232 at either the 250 or 1000 mg strength) compared with placebo (sugar pill) or acetaminophen 1000 mg after surgical removal of third molars. The primary endpoint will evaluate pain relief effectiveness up to 6 hours after administration of the study drug.

Detailed description:
This is a single-center, randomized, double-blind, placebo- and active-controlled, parallel group study to evaluate the efficacy, safety and pharmacokinetic profile of JNJ-10450232, administered as a single dose in capsules (250 or 1000 mg), over a 24 hour period after molar extractions. Subjects will stay at the research center for \~24 hours after administration of study drug. Healthy male subjects, ages 18 to 45 years inclusive, will be screened by medical history, vital signs, an electrocardiogram (ECG), and clinical laboratory tests. Eligible subjects will return to the clinic on the day of surgery and complete baseline vital signs and clinical laboratory tests. They will undergo dental extraction of a minimum of three third-molars and, if qualified, will be randomly assigned to one of four study treatments for pain.

Arms:
arm 1: None arm 2: None arm 3: None arm 4: None

Interventions: intervention 1: JNJ-10450232 / Not yet marketed intervention 2: JNJ-10450232 / Not yet marketed intervention 3: JNJ-10450232 / Not yet marketed intervention 4: acetaminophen / Tylenol
Intervention descriptions: intervention 1: Subjects who meet the randomization criteria at baseline within 4.5 hours after dental surgery will be assigned to one of four treatment groups stratified by pharmacokinetic blood sampling schedule and by baseline pain intensity level. intervention 2: Subjects who meet the randomization criteria at baseline within 4.5 hours after dental surgery will be assigned to one of four treatment groups stratified by pharmacokinetic blood sampling schedule and by baseline pain intensity level. intervention 3: Subjects who meet the randomization criteria at baseline within 4.5 hours after dental surgery will be assigned to one of four treatment groups stratified by pharmacokinetic blood sampling schedule and by baseline pain intensity level. intervention 4: Subjects who meet the randomization criteria at baseline within 4.5 hours after dental surgery will be assigned to one of four treatment groups stratified by pharmacokinetic blood sampling schedule and by baseline pain intensity level.
