The U.S. Tremfya market is poised for steady growth over the coming decade, expanding from USD 3.18 billion in 2024 to an estimated USD 5.45 billion by 2034. This represents a compound annual growth rate (CAGR) of 5.5% from 2025 to 2034. Tremfya (guselkumab), developed by Janssen Biotech (a Johnson & Johnson company), has established itself as a leading biologic therapy, particularly for treating moderate-to-severe plaque psoriasis and active psoriatic arthritis. The drug’s efficacy, durability, and favorable dosing schedule are contributing to its sustained market performance.
Fueled by increasing disease prevalence, broader biologic adoption, and continued clinical advancement, the U.S. Tremfya market is witnessing solid momentum. Furthermore, the biologic is gaining traction amid rising demand for patient-centered therapies with lower immunogenicity and sustained response profiles.

Key Market Growth Drivers
✅ Rising Incidence of Psoriasis and Psoriatic Arthritis in the U.S.
One of the primary drivers for Tremfya’s market growth is the increasing burden of autoimmune dermatological and rheumatological disorders, especially plaque psoriasis and psoriatic arthritis. According to the National Psoriasis Foundation, more than 7.5 million people in the U.S. live with psoriasis, and up to 30% of them develop psoriatic arthritis. With these figures climbing due to genetic, environmental, and lifestyle factors, the demand for reliable, long-term treatment solutions like guselkumab continues to grow.
✅ Preference for IL-23 Inhibitor Class Over Traditional Biologics
Tremfya belongs to the interleukin-23 (IL-23) inhibitor class, which has demonstrated superior selectivity and long-term disease control compared to older biologics such as TNF-alpha inhibitors. IL-23 inhibitors reduce inflammation by targeting a more specific immune pathway, leading to fewer side effects and lower systemic immunosuppression.
With better tolerability, sustained efficacy, and reduced need for frequent injections (administered just once every eight weeks after the initial loading dose), Tremfya is increasingly being adopted as a first-line or second-line therapy after TNF-alpha biologics or methotrexate failures.
✅ Expansion into Psoriatic Arthritis and Other Indications
While initially approved for moderate-to-severe plaque psoriasis, Tremfya's FDA approval was expanded in 2020 to include active psoriatic arthritis. This expanded label has significantly widened its market potential in the U.S., particularly among rheumatologists seeking targeted therapies for systemic autoimmune diseases.
In clinical trials such as DISCOVER-1 and DISCOVER-2, guselkumab demonstrated strong and sustained ACR20/50/70 responses, reduced joint swelling, and improved skin clearance. These results have bolstered physician confidence and influenced treatment guidelines.
✅ Strong Brand Backing and Market Access Programs
Being marketed by Janssen Biotech, a subsidiary of Johnson & Johnson, Tremfya benefits from robust marketing, insurance support programs, and market access strategies. Janssen's patient assistance initiatives, such as co-pay support and affordability programs, have helped maintain high adherence rates and expand Tremfya’s penetration in both Medicare and commercially insured populations.
Moreover, direct-to-consumer advertising and physician outreach programs continue to boost brand visibility in the competitive biologics space.

Market Challenges
Despite its strong performance, the Tremfya market faces several notable challenges:
Growing Competition from Other IL-23 Inhibitors
While Tremfya was among the early IL-23 inhibitors to gain FDA approval, it now faces increased competition from newer entrants such as:
- Skyrizi (risankizumab) – AbbVie’s fast-growing IL-23 blocker showing superior skin clearance
- Ilumya (tildrakizumab) – Sun Pharma’s cost-effective alternative with similar efficacy
- Cosentyx (secukinumab) – A popular IL-17A inhibitor that also competes for market share in psoriasis and PsA
These alternatives pose a threat by offering similar or improved efficacy, better payer coverage, or price differentiation.
High Cost of Therapy and Access Inequities
The annual cost of Tremfya therapy can exceed $60,000, which presents affordability issues for uninsured and underinsured patients. Despite Janssen’s co-pay programs, disparities in access persist, especially among low-income and minority populations.
Formulary restrictions, prior authorization requirements, and insurer step therapy protocols may delay or limit patient access, impacting market growth.
Biosimilar Threat on the Horizon
Though no biosimilar for guselkumab currently exists in the U.S. market, increasing regulatory clarity and patent expirations could pave the way for biosimilar entrants toward the end of the forecast period. The introduction of cost-effective biosimilars would significantly affect pricing strategies and market dynamics for Tremfya in the long term.
Regional Insights: U.S. Market Landscape
The U.S. remains the dominant market for Tremfya globally, supported by early biologic adoption, strong reimbursement frameworks, and a large diagnosed patient base.
▶️ Northeast and West Coast Lead in Adoption
States like California, New York, and Massachusetts have higher concentrations of specialty dermatology and rheumatology clinics, facilitating advanced biologic treatments. These regions also benefit from greater insurance penetration and access to tertiary care hospitals.
▶️ Midwest and Southern States Show Growth Potential
Although adoption is slightly lower in rural and low-income populations, increasing telemedicine access and awareness campaigns are improving diagnosis and treatment rates. Initiatives to train primary care physicians in biologic prescribing practices are also supporting market expansion.
Emerging Trends and Future Outlook
???? Biologic Personalization and Biomarker Research
The future of biologic therapy in dermatology and rheumatology will be shaped by personalized medicine. Researchers are investigating biomarkers that can predict treatment response to guselkumab, enabling precision prescribing and improving patient outcomes.
???? Real-World Data and Long-Term Safety
Post-marketing studies and real-world evidence (RWE) continue to affirm Tremfya’s safety and efficacy in diverse populations, including those with comorbidities or complex disease profiles. Long-term safety surveillance is a key differentiator as patients and physicians consider chronic use.
???? Digital Health and Adherence Tools
To enhance patient engagement and adherence, digital companion apps, virtual nurse coaching, and smart auto-injectors are being explored. These tools can track dosing schedules, monitor side effects, and streamline communication between patients and providers.
Conclusion
The U.S. Tremfya market is positioned for healthy growth through 2034, driven by increasing prevalence of autoimmune skin and joint disorders, strong clinical efficacy across indications, and growing confidence in IL-23-targeted therapy.
While competition and pricing pressures persist, Tremfya’s unique position in the biologics landscape—supported by robust clinical backing and patient support programs—makes it a key asset in the evolving immunology market. Continued investment in innovation, real-world data generation, and equitable access will be essential to maintaining its leadership position and realizing the projected USD 5.45 billion market size by 2034.
