An Open-label Extension Study Evaluating the Safety and Efficacy of Upadacitinib (ABT-494) in Adults With Rheumatoid Arthritis

Phase 2CompletedNCT02049138

AbbVie493 enrolled

Overview

The primary objective of the study is to evaluate the long-term safety, tolerability, and efficacy of upadacitinib in adults with rheumatoid arthritis (RA) who have completed a preceding randomized controlled trial with upadacitinib.

This is an open-label extension study to assess the long-term safety, tolerability, and efficacy of upadacitinib in adults with RA who have completed Study M13-550 (NCT01960855) or Study M13-537 (NCT02066389) Phase 2 randomized controlled trial (RCT) with upadacitinib. All participants received treatment with 6 mg upadacitinib twice a day at the start of the study. Participants may have been up-titrated to 12 mg BID based on protocol-specified criteria. In Protocol Amendment 2 (January 2016) the study treatment was changed to a once daily (QD) formulation. Participants receiving 6 mg BID were transitioned to 15 mg QD and participants receiving 12 mg BID were transitioned to 30 mg QD dosing. An optional 12-week vaccine sub-study was added in Protocol Amendment 3 (November 2017) to assess the impact of upadacitinib treatment (15 mg QD and 30 mg QD) with background methotrexate on immunological responses to pneumococcal 13-valent conjugate vaccine (PCV-13; Prevnar 13®) in RA patients. The vaccine substudy included 111 participants who were enrolled in the main study, the first participant was enrolled on 13 February 2018 and the the last participant completed the sub-study on 9 April 2020. In Protocol Amendment 5 (December 2019), the protocol was revised to allow a decrease in upadacitinib dosing from 30 mg QD to 15 mg QD, as appropriate, based on investigator's medical decision or for safety/tolerability concerns.

The Health Assessment Questionnaire - Disability Index is a patient-reported questionnaire that measures the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and errands and chores) over the past week. Participants assessed their ability to do each task on a scale from 0 (without any difficulty) to 3 (unable to do). Scores were averaged to provide an overall score ranging from 0 to 3, where 0 represents no disability and 3 represents very severe, high-dependency disability.

Time frame: Baseline (of the preceding RCT study) and Weeks 6, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 252, 264, 276, 288, 300, and 312

Change From Baseline in in Functional Assessment of Chronic Illness Therapy (FACIT) - Fatigue Scale Over Time

The FACIT Fatigue scale is a 13-item tool that measures an individual's level of fatigue during their usual daily activities over the past 7 days. Each of the fatigue and impact of fatigue items are measured on a four point Likert scale (4 = not at all fatigued to 0 = very much fatigued). The FACIT Fatigue Scale is the sum of the individual 13 scores and ranges from 0 to 52 where higher scores indicate better quality of life. A positive change from Baseline indicates improvement.

Time frame: Baseline (of the preceding RCT study) and Weeks 6, 12, 24, 36, 48, 72, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 252, 264, 276, 288, 300, and 312

Change From Baseline in Work Instability Scale for RA (RA-WIS) Over Time

RA-WIS is a tool to evaluate work instability (the consequence of a mismatch between an individual's functional ability and their work tasks). RA-WIS consists of 23 questions relating to the participant's functioning in their work environment, each answered as Yes or No. The total score is the number of questions answered Yes, and ranges from 0 to 23. A score \< 10 means low risk, scores between 10 and 17 indicate medium risk, and scores \> 17 indicate high risk of work instability. A negative change from Baseline indicates improvement in work instability.

Time frame: Baseline (of the preceding RCT study) and Weeks 6, 12, 24, 36, 48, 72, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 252, 264, 276, 288, 300, and 312

Change From Baseline in EuroQoL-5D (EQ-5D) Index Over Time

The EQ-5D-5L is a generic measure of health status consisting of two parts. The first part (the descriptive system) assesses health in five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) each of which is rated on 5 levels of severity (1: no problem, 2: slight problems, 3: moderate problems, 4: severe problems, 5: extreme problems). A health state index score was calculated from individual health profiles using a UK scoring algorithm. Health state index scores generally range from less than 0 (where 0 is the value of a health state equivalent to dead; negative values representing values as worse than dead) to 1 (the value of full health), with higher scores indicating higher health utility. The higher the score the better the health status. A positive change from baseline indicates improvement in health status.

Time frame: Baseline (of the preceding RCT study) and Weeks 6, 12, 24, 36, 48, 72, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 252, 264, 276, 288, 300, and 312

Change From Baseline in EuroQoL-5D VAS Score Over Time

The EQ-5D-5L is a generic measure of health status consisting of two parts. The second part of the questionnaire consists of a visual analog scale (VAS) on which the participant rates his/her perceived health from 0 (the worst imaginable health) to 100 (the best imaginable health). A positive change from baseline indicates improvement.

Time frame: Baseline (of the preceding RCT study) and Weeks 6, 12, 24, 36, 48, 72, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 252, 264, 276, 288, 300, and 312
