RealWorld Dynamix: Biologic/JAK Switching in Rheumatoid Arthritis US

There are currently nine biologics, one biosimilar, and three oral janus kinase (JAK) inhibitor approved for the treatment of rheumatoid arthritis (RA) in the United States. With the more established TNF-inhibiting biologics on the market for nearly two decades, RA treatment protocol and payer policy tend to dictate their use as first-line biologics. However, rheumatologists estimate that every year, roughly one-quarter of their RA patients treated with biologics or JAKs are switched from one biologic/JAK to another brand. Treatment protocols for second-line (and subsequent line) therapies are less stringent, resulting in a dynamic switching segment. This study provides independent analysis of the switching market, as the key driver and predictor of future brand share, delivering intelligence that is critical to informing commercial decisions.

RealWorld Dynamix™: Biologic/JAK Switching in RA (US) is based on a robust and deep patient chart analysis of ~1000 RA patients who were switched from one biologic or JAK-inhibitor to a different brand in the past three months. Each physician completes an in-depth medical history of their last five patients who met the study inclusion criteria. An excellent augmentation to claims data, this study also captures the clinician’s perspective on why the switch was made and the new brand chosen as well as future intentions should the response be suboptimal. In addition to patient demographics and treatment history, clinical assessments, diagnostic tests and laboratory values are included to provide insight into the clinical course of the disease.

The 2020 audit will be the fifth annual edition included in the service (trending since 2016).
