Evaluation of Sonelokimab in Patients With Active Psoriatic Arthritis Naive to Biologic Disease-Modifying Antirheumatic Drug

Study Purpose

This is a study to demonstrate the clinical efficacy and safety of sonelokimab administered subcutaneously compared with placebo in the treatment of adult patients with active psoriatic arthritis who are naive to biologic disease-modifying antirheumatic drug therapy.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

Participants have a confirmed diagnosis of psoriatic arthritis (PsA) per the 2006 Classification for Psoriatic Arthritis (CASPAR) criteria with symptoms for ≥6 months before the Screening Visit. 3. Participants have moderate to severe active disease (defined by a 68 tender joint count [TJC68] of ≥3 and a 66 swollen joint count [SJC66] of ≥3). 4. Participants have current active plaque psoriasis (PsO) or a dermatologist-confirmed history of plaque PsO. 5. Participants test negative for both rheumatoid factor and anti-cyclic citrullinated peptide at the Screening Visit.

Exclusion Criteria:

1. Participants with a known hypersensitivity to sonelokimab or any of its excipients. 2. Participants who have a diagnosis of chronic inflammatory conditions other than PsO or PsA. 3. Participants with a diagnosis of inflammatory bowel disease. 4. Participants who have experienced a period of ≥3 weeks of unexplained diarrhea in the 24 weeks before the Baseline Visit. 5.

Participants who have ever received any biologic immunomodulating agents for PsA or PsO, whether investigational or approved.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06641076
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 3
