Key Factors Driving the Growth of the Rheumatoid Arthritis Market 

Rising Rheumatoid Arthritis Disease Prevalence

According to DelveInsight's estimates, the US accounted for around ~1.3 million diagnosed prevalent cases of rheumatoid arthritis in 2024. These cases are further expected to increase by 2034.

Biologic DMARDs and JAK Inhibitors Fuel Future Market Expansion

Current therapies such as biological DMARDs showed promising results in treating rheumatoid arthritis patients, and market penetration is expected to be more in the future and expected to drive market growth. Oral classes such as JAKi are also expected to contribute to the rheumatoid arthritis market growth.

Rising Rheumatoid Arthritis Clinical Trial Activities

Emerging therapies like rabeximod (Cyxone), AZD1163 and AZD6912 (AstraZeneca), ocadusertib (Eli Lilly and Company), R-2487 (Rise Therapeutics), MYMD-1 (TNF Pharmaceuticals), SR-878 (SciRhom), and others are being developed for safe and efficacious treatment options.

Rheumatoid Arthritis Market Analysis

Since the introduction of the first biologic therapy over two decades ago, the treatment landscape for rheumatoid arthritis has undergone a remarkable transformation. The market today is well-established, featuring multiple blockbuster therapies. The approval of Etanercept paved the way for subsequent anti-TNF agents and other classes of rheumatoid arthritis treatments. Biologics, especially anti-TNFs, remain deeply entrenched as the standard of care, and despite the approval of several new therapeutic classes, none have achieved comparable influence or market penetration.

Approved treatments for rheumatoid arthritis include RINVOQ (AbbVie), OLUMIANT (Eli Lilly and Company), KEVZARA (Regeneron/Sanofi), and XELJANZ (Pfizer), among others. Meanwhile, emerging therapies such as rabeximod (Cyxone), AZD1163 and AZD6912 (AstraZeneca), ocadusertib (Eli Lilly and Company), R-2487 (Rise Therapeutics), MYMD-1 (TNF Pharmaceuticals), and SR-878 (SciRhom) are being developed to provide safer and more effective treatment alternatives. Notably, SciRhom has discontinued its Phase I trial for autoimmune disorders in Austria.

The market potential for rheumatoid arthritis therapies remains substantial; six of the world's top 50 bestselling drugs are currently used for rheumatoid arthritis treatment. Major pharmaceutical and biotechnology companies, including AbbVie, Amgen, Roche, Pfizer, Johnson & Johnson, and Bristol Myers Squibb, dominate the space. Many of these industry leaders have fortified their market positions through robust patent protections, effectively limiting biosimilar and generic competition.

Rheumatoid Arthritis Competitive Landscape

Some of the rheumatoid arthritis drugs in the pipeline include rabeximod (Cyxone), TAS5315 (Taiho Pharmaceutical), AZD1163 and AZD6912 (AstraZeneca), Ocadusertib (Eli Lilly and Company), R-2487 (Rise Therapeutics), MYMD-1 (TNF Pharmaceuticals), and others.

Cyxone's Rabeximod is an orally administered drug with a distinct mechanism of action that selectively targets inflammatory macrophages — white blood cells that play a central role in driving inflammation, tissue destruction, and clinical manifestations of rheumatoid arthritis (RA). It is considered particularly effective during the onset and flare-ups of RA, with strong potential to prevent joint damage and disease progression. The drug is currently in Phase II clinical trials.

Taiho Pharmaceutical's TAS5315 is a novel, highly selective Bruton's tyrosine kinase (BTK) inhibitor. By targeting BTK, the drug may help control inflammation and bone erosion by directly modulating effector cells, such as B cells, macrophages, and osteoclasts, involved in RA. A Phase II clinical trial is underway in Japan to assess the safety and efficacy of TAS5315 in combination with methotrexate in patients with RA who show an inadequate response to methotrexate alone.

AstraZeneca's AZD1163 is a first-in-class bispecific antibody designed to simultaneously inhibit peptidyl arginine deiminases (PADs) 2 and 4 — enzymes responsible for protein citrullination. This process generates autoantigens driving the autoimmune response in RA. By blocking PAD2 and PAD4, AZD1163 seeks to prevent the formation of these autoantigens.

AstraZeneca's AZD6912 is a small interfering RNA (siRNA) therapy targeting human Complement Factor B (CFB), a critical component of the alternative complement pathway. By suppressing hepatic CFB expression, AZD6912 aims to reduce systemic complement activation, thereby mitigating inflammation and tissue damage associated with rheumatoid arthritis.

The anticipated launch of these emerging therapies are poised to transform the rheumatoid arthritis market landscape in the coming years. As these cutting-edge therapies continue to mature and gain regulatory approval, they are expected to reshape the rheumatoid arthritis market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth.

Recent Developments in the Rheumatoid Arthritis Market

• In October 2025, Lifordi Immunotherapeutics, Inc. shared preclinical findings for its lead candidate, LFD-200, an ADC designed to deliver a potent glucocorticoid (GC) specifically to immune cells. The company also reported that its Phase 1 clinical trial of LFD-200 for Rheumatoid Arthritis has begun, with initial results from healthy participants (HPs) expected by the end of 2025.
• In October 2025, Kymera Therapeutics, Inc. reported new preclinical results for KT-579, a potent and selective oral IRF5 degrader, highlighting its disease-modifying potential across several immuno-inflammatory conditions. The data demonstrate that by specifically targeting and degrading IRF5, a key regulator of immune activity, KT-579 provides a novel oral strategy to inhibit multiple pro-inflammatory pathways involved in disorders like lupus and rheumatoid arthritis.
• In April 2025, Calibr-Skaggs Institute for Innovative Medicines (Scripps Research) received FDA clearance for their IND application to study switchable CAR-T therapy (CLBR001 + SWI019) in autoimmune diseases. The upcoming Phase 1 trial will assess safety and efficacy in patients with myositis, systemic sclerosis, lupus, and rheumatoid arthritis, with plans to potentially expand to other conditions.

What is Rheumatoid Arthritis?

Rheumatoid arthritis is a long-term, inflammatory autoimmune disorder that causes progressive and damaging polyarthritis. It is marked by persistent pain and joint deterioration, typically spreading from the smaller, distal joints to larger, proximal ones. The condition arises when the immune system mistakenly attacks the body's own healthy tissues, though its exact causes remain unclear. RA occurs more frequently in women, who account for roughly 75% of all cases, and it most commonly develops between the ages of 30 and 50.
