Continuation Study of Zasocitinib in Adults With Psoriatic Arthritis
Sponsor: Takeda
Summary
Psoriatic arthritis (PsA) is a long-term inflammatory disease that affects the joints and skin. The purpose of this study is to check how safe zasocitinib is, how well it is tolerated and how well it works in adults with PsA over a longer period of time. Adults who completed the 1-year (52-week) treatment period in one of the parent studies (TAK-279-PsA-3001 \[NCT06671483\] or TAK-279-PsA-3002 \[NCT06671496\]) may be able to join this continuation study (also called long-term extension or LTE study). All participants in this continuation study, will receive zasocitinib (lower or higher dose), once a day (QD). Each participant can be in this study for approximately 2 years (108 weeks). This includes a treatment period of up to 2 years (104 weeks) and a 1-month (4-week) follow-up period to monitor a participant's health.
Official title: A Phase 3, Multicenter, Long-Term Extension Study to Evaluate the Long-Term Safety, Tolerability, and Efficacy of Zasocitinib (TAK-279) in Subjects With Active Psoriatic Arthritis Who Are Either Biologic DMARD-Naïve or Biologic DMARD-Experienced, Including Those With Inadequate Response to Biologic DMARDs
