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.	NCT04761627
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

Additional Details

This is a multi-center study and will enroll approximately 480 participants. After eligibility confirmation, all participants will be randomized in a 1:1 ratio into 2 treatment arms: continued use of ustekinumab or multiple switches between ustekinumab and ABP 654 at Week 28. The randomization will be stratified by prior biologic use for psoriasis (yes versus [vs] no) at baseline (Week 0), geographic region, and baseline (Week 0) body weight. All participants will receive an initial 3 doses of ustekinumab on Day 1 (Week 0), Week 4 and Week 16. At Week 28, participants will be randomized to continue on ustekinumab or switching between ABP 654 and ustekinumab every 12 weeks. At Week 28, efficacy assessments will be conducted including evaluation of Psoriasis and Area Severity Index (PASI). Participants who do not achieve PASI 50 response or better improvement at Week 28 will be considered as run-in failures and will not be randomized at Week 28; these participants will complete End of Study procedures at Week 28. The run-in period will occur from Day 1 until randomization at Week 28. Those unable to complete the Week 28 visit or did not have a PASI assessment completed at Week 28 will be discontinued from the study. The total duration of study participation for each participant will be 68 weeks, with up to 4 weeks for screening and 64 weeks after the first investigational product administration.
