- Crohn’s Disease: Pending regulatory review based on promising Phase 3 clinical data.
Ongoing Clinical Trials and New Indications
As of Q1 2023, SKYRIZI is involved in over 35 clinical trials worldwide:
- Phase 3 Studies in Crohn’s Disease: Results from the ECLIPSE trial demonstrated significant improvement over placebo, leading to regulatory submissions in the U.S. and Europe.
- Psoriatic Arthritis Trials: The KIMPARK study assessed efficacy and safety, with preliminary data showing comparable performance to existing IL-23 inhibitors such as guselkumab.
- Additional Autoimmune Conditions: Trials investigating efficacy in hidradenitis suppurativa, uveitis, and ankylosing spondylitis are underway, reflecting AbbVie’s strategic focus on broad immunological indications.
Safety Profile
Across all trials, SKYRIZI has maintained a consistent safety profile:
- Adverse events primarily include upper respiratory infections and headache.
- No significant increase in serious infections or malignancies has been reported.
- Long-term data (up to 3 years) support sustained efficacy and tolerability.
Key Trial Results
- Efficacy in Plaque Psoriasis: Achieved PASI 75/90/100 responses in over 70%/50%/30% of patients at week 16.
- Psoriatic Arthritis: Demonstrated improvements in joint symptoms and skin lesions comparable to existing therapies.
- Crohn’s Disease: A pivotal trial achieved primary endpoints with a statistically significant higher remission rate versus placebo.
Market Analysis
Current Market Landscape
The global biologic market targeting plaque psoriasis and related autoimmune diseases is highly competitive. Key players include Pfizer’s Xeljanz, Lilly’s Taltz, Johnson & Johnson’s Stelara, and AbbVie’s Humira, alongside newer entrants like SKYRIZI.
- Market Penetration: As of 2023, SKYRIZI holds an estimated 15% share within the IL-23 inhibitor segment, amidst rising adoption rates driven by its favorable efficacy and safety profile.

- Geographic Expansion: Launches in emerging markets such as China, India, and Brazil, projected to contribute up to 40% of future revenue growth by 2027.
- Precision Medicine: Integration of biomarker-driven treatment protocols could optimize SKYRIZI’s positioning, leading to improved treatment outcomes and adherence.
Forecasts
- Revenue Projections: Analysts project SKYRIZI’s global sales to reach $4.5 billion by 2025, driven by increased penetration and additional indications (source: EvaluatePharma).
- Market Share Growth: Market share in IL-23 inhibitors is anticipated to reach 25-30% by 2027, overtaking older biologics like Stelara as the preferred option for certain indications.
- Pipeline Impact: Success in upcoming trials could provide a catalyst for sustained double-digit growth, with a compound annual growth rate (CAGR) of around 20% over the next 4 years.
Risks and Uncertainties
- Regulatory Delays: Any setbacks or delays in Crohn’s disease approval could impact sales forecasts.
- Competitive Innovation: Emergence of oral IL-23 inhibitors or biosimilars could erode SKYRIZI’s market dominance.
- Pricing and Reimbursement Policies: Changes in healthcare policies could impact profitability.
Key Takeaways
