Abstract

Chronic psoriasis, a prevalent immune-mediated skin disorder, is characterized by keratinocyte hyperproliferation and systemic inflammation. Over the last decade, immunotherapy has transformed its management, targeting specific immune pathways with unprecedented precision. This review explores the mechanistic basis of novel immunotherapeutic agents, evaluates their clinical efficacy, and discusses future innovations such as personalized medicine approaches. Advances in monoclonal antibodies, cytokine inhibitors, and small-molecule modulators have substantially improved disease outcomes, with many patients achieving sustained remission. However, challenges remain regarding longterm safety, cost-effectiveness, and equitable access to treatment. Integrating biomarker-guided therapy and novel delivery systems holds promise for improving patient care and reducing disease burden.

Introduction

Psoriasis is a chronic, relapsing inflammatory skin condition affecting approximately 2–3% of the global population, with significant impact on quality of life [1]. The pathogenesis involves genetic susceptibility, environmental triggers, and immune dysregulation, primarily driven by the **IL-23/Th17 axis**. Traditional treatments such as phototherapy and systemic agents provide symptomatic relief but are often inadequate for moderate-to-severe disease. **Immunotherapy** has emerged as a transformative approach, enabling targeted modulation of the immune system to achieve deeper and more sustained responses.

Mechanistic insights into immunotherapy

The **IL-23/Th17 pathway** plays a central role in psoriasis, promoting keratinocyte proliferation and inflammation. Novel **biologics** selectively inhibit cytokines like IL-17A, IL-17F, and IL-23p19, reducing skin lesions without broadly suppressing the immune system. By focusing on specific immune checkpoints and pro-inflammatory mediators, these agents achieve high efficacy with a lower risk of systemic side effects compared to older immunosuppressants.

Monoclonal antibody therapies

**Ustekinumab**, the first monoclonal antibody approved for psoriasis, targets the p40 subunit shared by IL-12 and IL-23 [2]. Subsequently, more specific **IL-23 inhibitors** such as guselkumab, tildrakizumab, and risankizumab have demonstrated superior efficacy and durability. These therapies provide high **PASI 90 and PASI 100** response rates, representing near-complete skin clearance for many patients.

IL-17 inhibitors and rapid clinical response

Drugs like **secukinumab** and **ixekizumab** directly block IL-17A, resulting in rapid onset of symptom improvement within weeks. **Bimekizumab**, which inhibits both IL-17A and IL-17F, offers even greater efficacy in reducing plaques and associated symptoms, including joint pain in psoriatic arthritis.

Small molecule modulators

Beyond biologics, **small molecule therapies** such as **apremilast** (a PDE4 inhibitor) offer oral administration and lower immunogenicity risk [3]. While generally less potent than monoclonal antibodies, they are valuable for patients with milder disease or those unsuitable for injectable treatments.

Safety and long-term outcomes

Long-term registry data indicate that most biologics maintain safety profiles with minimal increased risk of serious infections or malignancies. Nevertheless, vigilance is essential for monitoring rare adverse events, and more real-world studies are needed to assess sustained immunomodulation over decades.

Biomarker-guided therapy

**Biomarker discovery** is revolutionizing **personalized dermatology**, enabling stratification of patients likely to respond to specific agents [4]. Genetic and proteomic profiling can predict treatment efficacy, minimize trial-and-error prescribing, and reduce healthcare costs.

Future directions

Next-generation immunotherapies aim to combine **nanotechnology-based delivery systems** with targeted immune modulation for higher skin penetration and reduced systemic exposure [8]. There is also growing interest in oral biologics, bispecific antibodies, and microbiome-targeted treatments.

Challenges in global access

Despite the clinical success of immunotherapy, **cost** remains a major barrier in low- and middle-income countries [5]. Strategies such as biosimilar development, price negotiation, and insurance reform are critical to ensuring equitable access to these advanced treatments.

Conclusion

Immunotherapy has fundamentally reshaped the management of chronic psoriasis, offering patients unprecedented rates of remission. Future innovations—including biomarker-guided care, novel delivery platforms, and global affordability initiatives—hold promise for reducing the burden of this lifelong condition.
