What this trial studies

This observational study aims to explore the influence of sex and gender on the effectiveness of advanced therapies in patients with psoriatic arthritis (PsA). Conducted across approximately 30 international sites, the study will enroll 540 patients who have a confirmed diagnosis of PsA and are starting advanced therapy. Participants will undergo assessments before and after treatment initiation, with data collected through questionnaires and physical examinations to identify biological and socio-cultural factors affecting treatment response. The study will compare outcomes between male and female patients to better understand these differences.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a rheumatologist-confirmed diagnosis of active psoriatic arthritis who are planning to start advanced therapies.

Not a fit: Patients who are unable to read or write, cannot sign informed consent, or are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment approaches for psoriatic arthritis based on sex and gender differences.

How similar studies have performed: While the specific focus on sex and gender in this context may be novel, other studies have explored treatment responses in psoriatic arthritis with varying degrees of success.
