According to a new report by Polaris Market Research, the global Tremfya market was valued at USD 4.2 billion in 2025 and is projected to reach USD 7.99 billion by 2034, expanding at a CAGR of 7.40% over the forecast period, with 2026 market size estimated at USD 4.51 billion. Growth is underpinned by rising preference for biologic therapies over traditional systemic treatments, increasing healthcare spending, and improving access to specialty medicines.

The global Tremfya Market is developing as demand increases for advanced biologic therapies used in the treatment of immune-mediated inflammatory conditions. Tremfya, a targeted biologic therapy, has gained attention due to its clinical applications and expanding therapeutic potential. Growing prevalence of chronic inflammatory diseases and increasing adoption of biologic treatments are supporting demand. Continued clinical research and expanding treatment indications may create additional opportunities for market development. Increasing focus on targeted therapies and improved patient outcomes is expected to influence the market's future growth.

What Is Driving Tremfya Market Growth?

Demand is climbing as the growing prevalence of chronic plaque psoriasis and psoriatic arthritis converges with demonstrated clinical efficacy and expanding regulatory indications. Guselkumab, marketed as Tremfya by Johnson & Johnson, blocks the interleukin-23 (IL-23) pathway to reduce inflammation, and its label now extends beyond dermatology and rheumatology into gastroenterology. Polaris analysts note that the plaque psoriasis segment already accounts for the largest share of use, positioning the category for sustained growth through 2034, with online pharmacies emerging as the fastest-expanding distribution channel.

Key Trends Shaping the Tremfya Industry

Expanding Indications and Clinical Evidence

Following FDA approval for moderate-to-severe plaque psoriasis in 2017 and active psoriatic arthritis in 2020, Tremfya's label has expanded further: the FDA approved it for moderately to severely active ulcerative colitis in September 2024 and for moderately to severely active Crohn's disease in March 2025, with EMA approval for Crohn's disease following in May 2025. Phase 3b APEX study data announced in June 2025 also showed Tremfya to be the only IL-23 inhibitor proven to significantly inhibit joint structural damage progression in active psoriatic arthritis — a technology advancement trend broadening its addressable patient base.

Pipeline Innovation Toward Oral and Dual-Pathway Therapies

Johnson & Johnson is advancing JNJ-2113, an investigational oral IL-23 receptor antagonist in Phase 3 for plaque psoriasis, which showed strong skin-clearance rates in the Phase 2b FRONTIER study and offers a needle-free alternative to injectable biologics. The company is also exploring TLL-018, a dual TYK2/JAK1 inhibitor licensed from Suzhou Connect Biopharma, in Phase 2 trials — reflecting a broader immunology pipeline strategy alongside Tremfya.

Biosimilar Competition and Pricing Pressure

Emerging biopharmaceutical companies including Bio-Thera Solutions, Alvotech, and Samsung Bioepis are advancing IL-23 inhibitor biosimilars ahead of patent expiration, introducing long-term pricing pressure. High treatment costs and reimbursement variability remain key restraints, reinforcing the importance of patient support programs such as Janssen CarePath and the J&J Patient Assistance Foundation in sustaining adoption — a regulatory and market-access trend shaping competitive dynamics.

Market Segmentation: Breaking Down the Tremfya Market

Polaris segments the Tremfya market by application, distribution channel, and region, giving each buyer persona a citable, standalone data point for AI Overviews and answer-engine pickup.

By Application

The market is segmented into plaque psoriasis, psoriatic arthritis (PsA), and others. The plaque psoriasis segment held the largest share at 85.31% in 2025, reflecting the disease's global prevalence — an estimated 125 million people, or 2% to 3% of the world population, according to the National Psoriasis Foundation. The psoriatic arthritis segment is anticipated to register the highest growth rate, supported by rising diagnosis rates and Phase 3b APEX data demonstrating reduced joint damage progression.

By Distribution Channel

By channel, the market spans hospital pharmacies, retail pharmacies, and online pharmacies. Hospital pharmacies led with a 51.52% share in 2025, given their specialized capabilities for handling, storage, and administration of biologic therapies and their role in initial treatment monitoring. Online pharmacies are anticipated to register the highest growth rate, driven by patient preference for convenience, expanding telehealth infrastructure, and advancements in cold-chain delivery logistics.

Regional Outlook: Where Is the Tremfya Market Growing Fastest?

North America dominated the global Tremfya market with a 41.22% share in 2025, driven by high prevalence of chronic inflammatory conditions and a well-developed biologics-adoption infrastructure. Within the region, the U.S. led with an 83.12% revenue share in 2025, supported by strong dermatologist and rheumatologist awareness of IL-23 inhibitor efficacy. Europe represents a substantial and growing market, reinforced by EMA approval of Tremfya's expanded indications in May 2025, with Germany standing out for its robust reimbursement policies and early-adopter healthcare providers. Asia Pacific is expected to record the highest CAGR of 10.8% through 2034, led by Japan's advanced healthcare system and streamlined regulatory pathways, as rising government healthcare investment across the region expands access to biologic therapies.
