Clinical Trial Summary

The primary purpose of this proof-of-activity, phase 2 trial is to evaluate the safety and activity of orticumab in subjects with moderate to severe psoriasis and cardiometabolic risk factors.

Description:

This randomized, double-blind, study is designed to compare the effect of orticumab against placebo in subjects with moderate to severe psoriasis and cardiometabolic risk factors. A total of 75 subjects will be randomized in a double-blind fashion to receive intravenous (IV) infusions either of orticumab or placebo for up to 78 days.

Participants will be enrolled into one of the two groups: active treatment or placebo. Subjects will be randomized in a 2:1 ratio, orticumab to placebo and receive up to 11 weeks of treatment.

Planned treatments are weekly x 4 , then monthly x 2 . The Internal Safety Review Committee (ISRC) will review the blinded safety data after the first subject completes the first dose (Day 1), the first five subjects complete the first dose (Day 1), and the first ten subjects complete the first dose (Day 1). The IRSC will review all adverse reactions to all administered doses at these times.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in Coronary Artery Inflammation by CCTA	Change in coronary artery perivascular fat attenuation index (FAI) measured by coronary computed tomographic angiography (CCTA)	106 days (Week 15)
Other	Change in coronary artery plaque burden by CCTA	Change in total, noncalcified and low attenuation coronary artery plaque volume	106 days (Week 15)
Primary	Mean percent change from Baseline in Psoriasis Area Severity Index (PASI)	PASI combines the assessment of the severity of lesions and the area affected into a single score in the range 0 (no disease) to 72 (maximal disease)	106 days (Week 15)
Primary	Percentage of participants achieving treatment success by the 5-point static Investigator's Global Assessment modified 2011 version (sIGA) Score	Percentage of participants achieving treatment success (clear =0 or almost clear =1) and greater than or equal to (>=) 2 Point Improvement at Week 15 on the sIGA scale	106 days (Week 15)
Primary	Incidence of Treatment Emergent Adverse Events (TEAEs)		106 days (Week 15)
Primary	Incidence of serious adverse events (SAEs)		106 days (Week 15)
Primary	Incidence of abnormal hemodynamic parameters	heart rate (HR) and blood pressure (BP)	Weeks 3, 7, 11 and 15
Primary	Incidence of abnormal laboratory tests results		Weeks 3 and 15
Primary	Incidence of abnormal physical examination findings	Physical examination will include the following organ or body system assessments: general appearance; eyes; ears, nose, and throat; head and neck; chest and lungs; cardiovascular; abdomen; musculoskeletal; lymphatic; dermatological; neurological; and extremities.	Weeks 3, 7, 11, 15
Secondary	Mean percent change from Baseline in Psoriasis Area Severity Index (PASI)	PASI combines the assessment of the severity of lesions and the area affected into a single score in the range 0 (no disease) to 72 (maximal disease)	Weeks 1, 3, 7, and 11
Secondary	Percentage of Participants achieving PASI75 and PASI50	PASI75 is a 75 percent reduction in PASI score. PASI50 is a 50 percent reduction in PASI score	Weeks 1, 3, 7, and 11
Secondary	Mean percent change in Baseline in Body Surface Area (BSA) % involvement	Minimum: 0 percent, Maximum: 100 percent. Higher percentage indicates more skin with psoriasis.	Weeks 1, 3, 7, 11, 15
Secondary	Mean change from Baseline in Dermatology Life Quality Index (DLQI) score	DLQI is a ten-question questionnaire used to measure the impact of skin disease on the quality of life of an affected person. Each question is scored from 0 to 3, giving a possible score range from 0 (meaning no impact of skin disease on quality of life) to 30 (meaning maximum impact on quality of life).	Weeks 3, 7, 11, 15
Secondary	Mean change from Baseline in Itch Numerical Rating Scale (INRS) Score	The Itch NRS is a self-administered subject reported outcome questionnaire that is completed during protocol specified clinic visits. Participants indicate itch severity by circling the integer that best describes the worst level of itching due to psoriasis in the past 24 h on an 11-point scale anchored at 0, representing 'no itching' and 10, representing 'worst itch imaginable'.	Weeks 3 and 15
