An estimated 125 million people worldwide live with psoriasis. Those affected show a standardized mortality ratio between 1.0 and 1.6 along with 1.5 to 2.0 times the risk of depression. Trial data indicate strong biologic response rates that exceed real world treatment coverage.
Key Takeaways
- Patients with psoriasis have increased mortality risk; standardized mortality ratio estimates range from 1.0 to 1.6 across studies
- Psoriasis is associated with a 1.5–2.0x increased risk of depression compared with controls (meta-analytic estimate range)
- 125 million people worldwide are estimated to have psoriasis
- 17% of psoriasis patients have scalp involvement
- 16.4% of adults with psoriasis had moderate-to-severe disease severity (PASI ≥10)
- 1.2% of adults in the UK have psoriasis
- 30% of psoriasis patients develop psoriatic arthritis
- 12% of patients with psoriasis achieve PASI 90 with systemic/biologic therapy within 12–16 weeks in trial settings (meta-analytic estimate)
- 80% of patients treated with adalimumab reach PASI 75 by week 16 in pivotal trials
- 67% of patients treated with ustekinumab reach PASI 75 by week 12–16 in pivotal trials
- The global psoriasis drugs market is projected to reach $XX.X billion by 2030 (forecast range)
- The global psoriasis therapeutics market is projected to reach $XX.X billion by 2032 (forecast range)
- The global psoriasis treatment market was valued at $XX.X billion in 2023 (market sizing publication)
- Worldwide sales of secukinumab were $4.4 billion in 2023 (company annual report figure)
- Outpatient costs represented 83.5% of total psoriasis-related healthcare costs (US estimate)
With up to 125 million people affected, psoriasis raises mortality and depression risk and many patients still need effective systemic treatment.
