BMS-986322

PASI is a measure of the average erythema, induration thickness, and scaling of psoriatic skin lesions (each graded on a 0 to 4 scale), weighted by the area of involvement (head, arms, trunk to groin, and legs to top of buttocks). The PASI produces a numeric score that can range from 0 to 72, with higher PASI scores denoting more severe disease activity. The PASI-75 response rate is defined as the percentage of participants with moderate-to-severe PsO achieving at least 75% reduction from baseline in PASI score. Baseline is defined as the last measurement on or prior to date/time of first dose of study treatment.

Treatment related adverse events, serious adverse events and treatment related adverse events leading to treatment discontinuation are considered safety related events.

Mild TEAE: An event that is easily tolerated by the participant, causing minimal discomfort, and not interfering with everyday activities. Moderate TEAE:An event that causes sufficient discomfort and interferes with normal everyday activities. Severe TEAE: An event that prevents normal everyday activities. An AE that is assessed as severe should not be confused with an SAE. Severe is a category utilized for rating the intensity of an event, and both AEs and SAEs can be assessed as severe.

Number of participants with AE indicating clinical laboratory abnormality

Number of participants with clinically significant changes from baseline in ECG evaluations. ECG results for participants with any result outside of a pre-specified range and investigator identified abnormalities will be listed for the Safety Population. The following criteria will be used to determine ECG results that are outside of a pre-specified range: * PR (msec): Value \> 200 * QRS (msec): Value \> 120 * QT (msec): Value \> 500 or change from baseline \> 30 * QTcF (msec): Value \> 450 or change from baseline \> 30

Number of participants with clinically significant changes from baseline in vital signs evaluations. Vital signs for participants with any out-of-range result will be listed for the Safety Population. The following criteria will be used to determine vital sign results that are outside of a prespecified range, where changes from baseline are based on matched postural positions: * Heart Rate (bpm): Value \> 100 and change from baseline \> 30, or Value \< 55 and change from baseline \< -15 * Systolic blood pressure (mmHg): Value \> 140 and change from baseline \> 20, or Value \< 90 and change from baseline \< -20 * Diastolic blood pressure (mmHg): Value \> 90 and change from baseline \> 10, or Value \< 55 and change from baseline \< -10 * Respiration (breaths/min): Value \> 16 or change from baseline \> 10 * Temperature (°C): Value \> 38.3 or change from baseline \> 1.6

Number of participants with clinically significant changes from baseline in physical examination evaluations
