Phototherapy Market Growing While Psoriasis Drug Market Declines, Reports National Biological Corporation

BEACHWOOD, Ohio--()--While the global market for psoriasis drugs has declined 11% due to the recent COVID-19 Pandemic, the demand for phototherapy devices has grown substantially. 1 This recent shift is due to lockdown measures and the ongoing safety of patients and medical staff.

“We are seeing double-digit growth in demand for our products,” shared Haley White, Chief Commercial Officer for National Biological Corporation.

Historically patients have turned to phototherapy because it costs less than biologics and is effective or more effective in treatment. According to a JAMA Dermatology study, a biologic prescription costs up to $25,000 annually to maintain. In contrast, a phototherapy device costs up to $6,000 and can be utilized for years. 2

With COVID-19, the American Academy of Dermatology has issued new guidelines for the use of biologics due to growing concerns about the effects of those drugs on the immune system. In some instances, the AAD recommends postponing or discontinuing prescription treatment altogether.3

More than 8 million Americans are affected by psoriasis. 4 Phototherapy, also known as light therapy, treats psoriasis by slowing the rate of skin cell production safely through exposure to the use of ultraviolet light. Patients can seek phototherapy treatment at a clinic or in the comfort of their home. Treatment requires a doctor’s prescription. 5
