Patient Benefits

Patients who screen and then enroll in the study will receive:

  • Doctor Assessments
  • Lab work and Safety Follow-ups
  • Study drug (active, comparator, or placebo)
  • $52.00 per completed study visit ($936 Maximum for the course of the study.)

Study Duration

Study Duration for Patients

The total study duration is approximately 36-weeks which consists of approximately 10 visits during the course of the study.

The study consists of three periods:

  1. Screening Period (2 to 6 weeks before the treatment starts) to see if you are eligible to participate in the study.
  2. Study Treatment Period (24 weeks). This Study Treatment period includes a Double-Blind Study Treatment Period (24 weeks). Double-blind means you and your study team will not know which of the two treatment therapies you will receive.
  3. Safety Follow-Up Visit (SFU visit) (16 weeks, after the last dose of study drug) This visit will ensure you have no long-term safety concerns after the end of treatment.

The study may also have some unplanned visits, most commonly for repeat lab work.

Study Drug

Guselkumab (Tremfya) and Golimumab (Simponi)

Guselkumab (Tremfya) and Golimumab (Simponi) are both monoclonal antibody therapies. Enrolled subjects will either receive a combination of the two therapies (66.7%) or only Guselkumab (33.3%).
