Read MoreHide Full Article

Key Takeaways

  • ABBV's Rinvoq gains EU approval for pJIA in patients aged two years and older with inadequate DMARD. response.
  • Rinvoq's pJIA approval was supported by SELECT-YOUTH data showing gains in disease activity by week 12.
  • By week 48, Rinvoq's ACR Pediatric 70 response reached 79.5%, while clinical remission rose to 43.4%.

AbbVie (ABBV - Free Report) announced that the European Commission ("EC") has approved its blockbuster immunology drug, Rinvoq (upadacitinib), for a new indication. The drug is approved in the European Union for the treatment of active polyarticular juvenile idiopathic arthritis (pJIA) in patients aged two years and older who have had an inadequate response or intolerance to disease-modifying antirheumatic drugs (DMARDs).

The approval marks the 11th indication for Rinvoq in the European Union, further expanding the drug’s use across chronic inflammatory diseases. For pJIA, Rinvoq can be used either as monotherapy or in combination with methotrexate.

Rinvoq is already approved in the United States for the treatment of pJIA. In the European Union, the drug is approved across several other chronic inflammatory conditions, including ulcerative colitis, Crohn’s disease, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, giant cell arteritis and atopic dermatitis.

In July, the EC approved Rinvoq for alopecia areata and vitiligo. Regulatory applications for both indications are currently under review in the United States.

Juvenile idiopathic arthritis is the most common rheumatic disease in children, affecting an estimated 126,000 children in Europe. pJIA is a subtype that causes inflammation in joints, including the hands, feet, knees, hips and ankles, lasting for at least six weeks.

Year to date, ABBV's shares have rallied 18.5% compared with the industry’s 14.2% growth.

Rinvoq’s EC Approval for pJIA Validates ABBV’s Clinical Data

The EC approval for pJIA was supported by results from the open-label phase I SELECT-YOUTH study, along with data from adult patients with rheumatoid arthritis. The study showed meaningful improvements in disease activity as early as week 12, with responses continuing to improve through week 48. At week 12, 66.4% of patients achieved an ACR Pediatric 70 response, which increased to 79.5% by week 48.

The proportion of patients achieving clinical remission increased from 23% at week 12 to 43.4% at week 48. Patients additionally reported improvements in physical functioning and pain, supporting the potential benefits of Rinvoq in children with pJIA.

The treatment response in children with pJIA was generally similar to that seen in adults with rheumatoid arthritis.

Rinvoq: A Key Growth Driver for ABBV

Rinvoq is a key growth driver for AbbVie. Sales of the drug soared 22.2% year over year to $4.64 billion in the first half of 2026, driven by strong demand for all approved indications. In 2026, AbbVie expects Rinvoq revenues to be around $10.2 billion.

The drug is being evaluated in late-stage studies for hidradenitis suppurativa, Takayasu arteritis and systemic lupus erythematosus. It is also being studied in children with systemic juvenile idiopathic arthritis, atopic dermatitis, ulcerative colitis and Crohn’s disease. Phase III data for Rinvoq in hidradenitis suppurativa and systemic lupus erythematosus are expected in 2026.
