What is the approval history and clinical development pathway of Rinvoq?

Overview of Rinvoq

Introduction to Rinvoq Rinvoqq (upadacitinib) is an oral, once-daily small molecule inhibitor belonging to the Janus kinase (JAK) inhibitor class. Developed by AbbVie scientists, it is designed with selective reversible inhibitory activity; in vitro cellular assays demonstrate that Rinvoq preferentially blocks JAK1 or JAK1/3 signaling while sparing less of the signaling mediated by JAK2, thereby yielding its distinctive pharmacologic profile. It was engineered to manage immune-mediated inflammatory responses by tempering cytokine signaling pathways that drive the pathologic processes seen in chronic immune disorders. Because of its unique mechanism, Rinvoq has become a transformative option in the treatment of several autoimmune disorders, influencing the evolving paradigm in immunomodulatory therapies. Moreover, its oral administration route provides a convenience advantage over injectable biologics, and its once-daily dosing regimen enhances patient adherence and quality of life. Rinvoq’s rapid onset of action and durable clinical responses have further underscored its potential in altering the disease trajectory in patients affected by chronic inflammatory diseases.

Indications and Uses
Rinvoq is approved for a broad range of indications that reflect its versatility in treating immune-mediated conditions. Initially, it was approved for adults with moderately to severely active rheumatoid arthritis (RA) who had an inadequate response or intolerance to methotrexate or other disease-modifying antirheumatic drugs (DMARDs). Beyond rheumatoid arthritis, the approved uses have expanded considerably over time. It is also indicated for active psoriatic arthritis (PsA) and active ankylosing spondylitis (AS), as well as for non-radiographic axial spondyloarthritis (nr-axSpA) when accompanied by objective signs of inflammation. In addition, Rinvoq enjoys approvals in the gastrointestinal space; it is indicated for the treatment of moderately to severely active ulcerative colitis (UC) and, more recently, for Crohn's disease, thus becoming a valuable treatment option for patients in need of an oral therapeutic option in inflammatory bowel diseases (IBD). Moreover, Rinvoq has once again expanded its footprint into the dermatological realm by receiving approval for moderate-to-severe atopic dermatitis (AD) in adults and adolescents aged 12 and older. These multiple approved indications testify to the broad anti-inflammatory potential of Rinvoq across different organ systems and chronic inflammatory diseases.

Regulatory Approval History

Initial Approval and Indications
Rinvoq’s regulatory journey began with its initial approval in August 2019 by the U.S. Food and Drug Administration (FDA). This landmark authorization was granted based on robust data from pivotal Phase III trials conducted in adults with moderately to severely active rheumatoid arthritis who had an inadequate response or intolerance to methotrexate. The FDA approval was a culmination of a thorough review of multiple clinical endpoints, including improvements in joint pain, function and markers of inflammatory activity. At the time, the approved indication was narrowly scoped to rheumatoid arthritis, which was the first manifestation of its clinical potential. Simultaneously, this approval was also followed by the European Commission’s authorization for the treatment of adult rheumatoid arthritis in patients who had an inadequate response to one or more DMARDs, thereby laying the foundation for its international acceptance. The initial indications mainly focused on rheumatic diseases, pointing to the drug’s strong immunomodulatory effects in conditions characterized by systemic inflammation. This early approval signaled a major advancement amidst a crowded RA therapeutic landscape and provided a new oral alternative to biologic agents.

Subsequent Approvals and Label Expansions
Following its initial success in rheumatoid arthritis, Rinvoq’s label underwent a series of expansions as further clinical data emerged. AbbVie’s clinical development program demonstrated consistent efficacy and manageable safety profiles in other immune-mediated conditions. The indications in psoriatic arthritis and axial spondyloarthritis were added, expanding the drug’s utility into other rheumatic diseases. Regulatory agencies in both the U.S. and Europe recognized these benefits, and label expansions allowed Rinvoq to be used either as monotherapy or in combination with methotrexate in these patient populations. During subsequent years, Rinvoq’s label further expanded into the gastrointestinal arena with approvals for moderate to severe ulcerative colitis, driven by convincing clinical data from multiple Phase III induction and maintenance studies that showed statistically significant improvements in clinical remission and endoscopic response. More recently, regulatory agencies have approved Rinvoq for the treatment of Crohn’s disease, marking its seventh overall indication; this approval not only underscores its versatility but also its emerging role as the first approved oral treatment option in Crohn’s disease. Additionally, in 2022, the FDA approved Rinvoq for moderate to severe atopic dermatitis in adults and adolescents 12 years and older, based on data from large registrational Phase III studies that demonstrated rapid itch relief and improvement in skin clearance outcomes. Each successive approval has been supported by extensive clinical trials, and the label expansions have cemented Rinvoq’s position as a multi‐indication therapy with broad therapeutic reach across rheumatologic, gastrointestinal, and dermatologic conditions.

Clinical Development Pathway

Preclinical Studies
Before entering human trials, Rinvoq underwent extensive preclinical testing to elucidate its pharmacological properties and ensure an acceptable safety profile. These early studies, performed in vitro and in animal models, focused on assessing its inhibitory potency on various JAK enzymes. Preclinical data demonstrated that Rinvoq preferentially inhibits JAK1—and to some extent JAK1/3 signaling—while sparing receptors that depend on JAK2, suggesting a more favorable balance between efficacy and safety compared to non-selective JAK inhibitors. Animal model studies were instrumental in determining the initial dosing parameters and assessing the compound’s potential toxicity, pharmacokinetics (absorption, distribution, metabolism, elimination), and pharmacodynamics (effects on cytokine signaling pathways). The promising preclinical profile provided the impetus to advance Rinvoq into clinical development, a process which was closely monitored by regulatory bodies.

Phase I, II, and III Clinical Trials
The clinical development of Rinvoq followed a traditional pathway through Phase I, II, and III trials, each designed to build on its safety and efficacy profile in a stepwise manner.
In Phase I studies, healthy volunteers were administered single and multiple doses of upadacitinib to evaluate its safety, tolerability, and pharmacokinetic parameters. Detailed drug–drug interaction studies were also conducted, such as evaluations involving potential inhibitors or inducers of CYP3A4 to understand how Rinvoq would behave in a real-world polypharmacy setting. These studies were crucial in establishing a foundation for dose selection and optimizing the dosing regimen for subsequent trials.

Phase II studies were initiated in patient populations to assess the preliminary efficacy of Rinvoq as well as further characterize its safety profile in target conditions. Early studies in rheumatoid arthritis, for instance, showed promising results with significant improvements in disease activity scores and biomarkers of inflammation. Phase II trials also included dose-ranging studies to ascertain the optimal doses needed to achieve a meaningful clinical response while minimizing adverse events. In addition, exploratory trials in other indications such as psoriatic arthritis, atopic dermatitis, and ulcerative colitis provided early signals regarding the broad therapeutic potential of the drug.

Based on the encouraging results from Phase I and II trials, multiple large-scale Phase III studies were undertaken across different indications. For rheumatoid arthritis, the pivotal SELECT-COMPARE trial, among other studies, evaluated Rinvoq’s efficacy and safety in a head-to-head comparison with established biologic agents, demonstrating rapid onset and sustained clinical improvements. Similar robust Phase III programs were executed in psoriatic arthritis (e.g., SELECT-PsA 2), axial spondyloarthritis (e.g., SELECT-AXIS 1 and SELECT-AXIS 2), and inflammatory bowel diseases (e.g., U-ACHIEVE, U-ACCOMPLISH for ulcerative colitis and U-EXCEED, U-EXCEL, U-ENDURE for Crohn’s disease).
The results of these Phase III trials consistently showed that Rinvoq was superior to placebo in achieving co-primary endpoints (such as clinical remission, endoscopic response, and corticosteroid-free remission) and improved key secondary endpoints (including patient-reported outcomes, improvements in skin clearance in AD, and radiographic progression in RA). Furthermore, the long-term extension studies from these trials provided essential data on the durability of clinical benefits and the long-term safety profile, thus supporting its continued clinical use. In each phase, data related to efficacy, adverse events, laboratory parameters (including hepatic transaminase elevations, lipid changes, and risk of infections), and quality of life outcomes were rigorously analyzed, ensuring that regulatory decisions were anchored in comprehensive evidence.
