Psoriasis clinical trials at UCLA

The main aim of this study is to check the side effects of TAK-279 and how well it is tolerated in participants with moderate-to-severe plaque psoriasis. All participants will be assigned to study treatments of TAK-279 and will be treated with TAK-279 if the participants meet the study rules. Participants will be in the study for up to 217 weeks, including up to 35 days for the screening period, 52 weeks (Part A) up to 156 additional weeks (Part B) study treatment and 4 weeks follow up period. During the study, participants will visit their study clinic multiple times.

The goal of this clinical trial is to learn if ESK-001 works to treat moderate to severe plaque psoriasis. The main questions it aims to answer are: - Does ESK-001 reduce the severity of people's psoriasis? - How safe is ESK-001 in people with moderate to severe plaque psoriasis? The study includes 2 comparators: a placebo control (a 'dummy' tablet that does not contain the medicine ESK-001 but looks just like it) and an active control (apremilast, which is a medicine approved to treat psoriasis). People taking part in this study must be men or women aged at least 18 years and have had plaque psoriasis for at least 6 months, currently moderate to severe. Participants will: - take drug every day for 24 weeks. - visit the clinic for checkups and tests. - fill out questionnaires about their psoriasis, itch severity, and change in quality of life. - be assessed for health issues and side effects, physical examinations, vital signs, heart electrical activity measurements, and psychological health. - provide blood and urine samples.
