What Does the Future of Plaque Psoriasis Treatment Market Look Like?

Apr 07, 2023

Psoriasis is a common skin condition that accelerates the life cycle of skin cells. More than 3% of the adult population in the United States suffers from psoriasis. That equates to more than 7.5 million US adults. According to the World Psoriasis Day Consortium, 125 million people worldwide (2-3% of the total population) have psoriasis. According to the National Psoriasis Foundation (NPF), more than 8 million Americans suffer from psoriasis. As per Delveinsight’s estimates, the total prevalent population of psoriasis in the seven major markets was around 16 million cases in 2021. Plaque psoriasis is the most common type of psoriasis, affecting 80% of people with the disease. According to the latest published “Plaque Psoriasis Epidemiology” report, it was found that males are slightly more affected by plaque psoriasis than females.

The Current Plaque Psoriasis Treatment Space

There is currently no cure for psoriasis, but plaque psoriasis treatment can slow the growth of skin cells and relieve pain and itching. The severity of the disease determines the type of plaque psoriasis treatment. Phototherapy alone or in combination with systemic agents is generally recommended for moderate to severe plaque psoriasis treatment. The first line of active plaque psoriasis treatments includes the use of topical agents such as moisturizers, vitamin D creams, topical retinoids, and medications such as TAZORAC®, Duobrii (Ortho Dermatologics), and coal tar. TAZORAC (Allergan, Inc) Gel, 0.05%, and 0.1% are indicated for the topical plaque psoriasis treatment with up to 20% body surface area involvement.

It was approved by the FDA in 1997 and is widely used as a topical agent for plaque psoriasis treatment. Duobrii (Ortho Dermatologics) is a combination of the corticosteroid halobetasol propionate and the retinoid prodrug tazarotene. It was approved by the FDA in 2019 and is specifically indicated for topical plaque psoriasis treatment in adults. Phototherapy, oral-systemic agents, and injectable biological therapies are recommended when topical therapy fails. Phototherapy is a mainstay moderate to severe psoriasis treatment, particularly when topical agents are ineffective. It comes in psoralen plus UVA, broadband UVB, and narrowband UVB formulations (NB-UVB). As demonstrated in multiple RCTs, NB-UVB therapy is frequently used as a first-line plaque psoriasis treatment due to its efficacy and safety benefits.

Systemic plaque psoriasis treatments are frequently used in conjunction with topical therapy and phototherapy for patients with severe psoriasis. Oral agents and injectable biological therapies are currently available as systemic plaque psoriasis treatments. Among the FDA-approved drugs for plaque psoriasis treatment are Amevive (Biogen IDEC), Cimzia (UCB), Cosentyx (Novartis), Ilumya (Sun Pharmaceuticals), Otezla (Celgene), Skyrizi (AbbVie), and many others.

Future Directions in the Plaque Psoriasis Treatment

The history of psoriasis treatment over the last century celebrates the advances made in understanding and caring for patients with this disease. This progress has been made possible thanks to the collaboration of clinicians, patients, academics, and the pharmaceutical industry. While a cure for psoriasis is unlikely in the near future, complete eradication of the disease with the most recent biologic therapies is now a realistic goal for some. A whole-person approach to disease management that incorporates the P4 medicine principles of prediction, prevention, individualized therapy, and patient participation is a logical extension of our understanding that psoriasis is a “systemic disease” with significant physical and psychosocial consequences.

Although systemic psoriasis therapy has advanced significantly, there is still an unmet need for more effective topical therapies and wider use of biosimilars. The use of integrated multi-omic data to stratify patients and guide therapy will be the focus of future research. Improved access to care and early intervention with systemic therapy are topics that are being debated more and more. This is where service development and research intersect, necessitating innovative approaches and research methodologies to achieve this goal.

FAQs

1. What is plaque psoriasis?

2. What are the plaque psoriasis symptoms?

Psoriasis is distinguished by small scaly, red bumps. These bumps usually join together to form elevated skin plaques and are most visible on the elbows, knees, and scalp, though any skin area can be affected. The most common plaque psoriasis symptoms are itchiness, skin pain, joint pain, cracked, dry skin, and others.

3. How is plaque psoriasis diagnosed?

As psoriasis can resemble eczema and other skin conditions, the plaque psoriasis diagnosis can be difficult. The doctor may need to do a biopsy in some circumstances. 

4. What are the current plaque psoriasis treatment options?

Plaque psoriasis treatment modalities are selected based on disease severity, relevant comorbidities, patient preference (including cost and convenience), efficacy, and individual patient response evaluation. Although there is no cure for psoriasis, numerous effective plaque psoriasis treatment options exist, with topical therapy being the standard of care.
