AbbVie M16-852 Clinical Research Study

A Study to Evaluate the Safety and Efficacy of Upadacitinib in Participants With Giant Cell Arteritis (also known as Temporal Arteritis).

AbbVie M16-852 Clinical Research Study

Patient Benefits

If you pass screening and enroll in the study you will receive:

  • You may receive study drug (active or placebo), lab work, and visit exams at no cost.
  • You will be reimbursed $95.00 per completed study visit for transport costs with a maximum benefit of $2,375 for the course of the study.

Study Duration

Study Duration for Patients

The total study duration is approximately 104-weeks which consists of approximately 20 visits during the course of the study.

The study consists of four periods:

  1. Screening Period (2 to 5 weeks before the treatment starts) to see if you are eligible to participate in the study.
  2. Period 1 (52 weeks). In Period 1 of the study, you will be randomly assigned by chance (like the flip of a coin) to receive either upadacitinib plus a corticosteroid (CS) taper or placebo plus a CS taper. You will have a 75% chance of receiving upadacitinib and a 25% chance of receiving placebo.
  3. Period 2 (52 weeks). If you have no GCA signs and symptoms for at least 16 weeks before your Week 52 visit you will then continue to Period 2. If you were assigned to receive upadacitinib in Period 1, you will be randomly assigned to continue receiving the same dose of upadacitinib or switch to placebo. You will have a 66% chance of continuing to receive upadacitinib and a 33% chance of receiving placebo.
  4. Safety Follow-Up (approximately 30 days after final dose of study drug). This visit is for all patients who leave the study early or complete the study.

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