Patient Outcomes: Real World Evidence in Rheumatoid Arthritis (POWER)

Study Purpose

This is a prospective, real-world observational study in which patients with RA who are initiating treatment with a JAK inhibitor medication will self-report disease activity and treatment satisfaction measures using their own web-enabled device such as a smartphone. Secondary objectives include analyzing the epidemiology and natural history of the disease, its comorbidities, and current treatment practices.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

A patient MUST satisfy all of the following criteria to be eligible for enrollment into the POWER study: 1. Patient is currently participating in the Corrona RA Registry OR is eligible to participate and enrolls into the RA Registry prior to POWER study registration. 2. Patient is willing and able to complete online weekly surveys about their RA using their own computer, tablet,or smartphone and have a valid email address. 3. Patient is literate in English. 4. Patients provides consent for their data to be included in ArthritisPower™ registry in addition to providing consent to participate in the POWER study itself. 5. In conjunction with POWER registration: 1. A Corrona RA Registry Enrollment or Follow-up visit is conducted (includes both the Provider and Subject questionnaires and most recent Lab/Imaging Results if available) 2. Patient is newly prescribed* or receives their first dose of one of the following JAK-inhibitor medications: OLUMIANT® (baricitinib), RINVOQ™ (upadacitinib), or XELJANZ / XELJANZ XR® (tofacitinib)**, or any other JAK inhibitor approved during the study period.
  • - The decision to treat with a new therapy must precede the decision to recruit the patient into this study.
Prior use of a JAK-inhibitor medication does not exclude a patient from enrollment.
  • - Patients switching to and from either formula of tofacitinib (Xeljanz 5 mg BID or the "once daily" XR 11 mg version) do not qualify for the POWER study.

Trial Details

Trial ID:

This trial id was obtained from, 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.


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.

Patient Outcomes: Real World Evidence in Rheumatoid Arthritis (POWER)
Additional Details

The primary objective of this study is to analyze self-reported disease activity outcomes and treatment satisfaction measures in the real world using a bring-your-own-device approach for patients with rheumatoid arthritis who are initiating a JAKi medication. An exploratory objective is to assess the feasibility of using smartphone or web-based data collection to expand upon the insights gained through the Corrona RA Registry which uses a traditional site-based approach. POWER is a prospective, non-interventional study that will collect structured real-world data from patients with RA using a patient-centered mobile health application called ArthritisPower™. Patients planning to start treatment with a JAKi medication will self-report disease activity and treatment satisfaction through their first 3 months of therapy using their own web-enabled device such as a smartphone or computer. Patients will be recruited from the Corrona RA Registry at the time of a routine clinical encounter. After POWER registration, the remainder of the study is carried out using an automated data collection schedule via the web-based ArthritisPower™ application. Patients may complete assessments using a web browser or by downloading the free ArthritisPower™ application to a smartphone or tablet.
