Future Directions for GPP Management and Key Takeaways
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists discuss spesolimab’s place in therapy for treating generalized pustular psoriasis (GPP), address remaining unmet treatment needs, and share the types of future data they would like to see, along with key takeaways and advice for dermatologists managing patients with GPP.

Utilizing Intravenous and Subcutaneous Formulations of Spesolimab
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists compare the results of the EFFISAYIL-1 and
-2 trials with real-world use of spesolimab; discuss treatment expectations with patients; and explore the similarities, differences, and management roles of intravenous (IV) and subcutaneous (SQ) formulations, with strategies for timely IV therapy initiation during flares.

Overview of Spesolimab for Management of GPP
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists provide an overview of spesolimab, an IL-36R inhibitor now FDA-approved for treating GPP, discussing the efficacy and safety data from the EFFISAYIL-1 trial (intravenous [IV] formulation) and the EFFISAYIL-2 trial (subcutaneous
[SQ] formulation).

Role of IL-36 in GPP Pathogenesis and Treatment
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists describe the role of the IL-36 pathway in the pathogenesis of generalized pustular psoriasis (GPP) and discuss how IL-36 inhibition can be a key strategy in managing the disease.

Addressing the Psychosocial Aspects of GPP Management and the Role of Multidisciplinary Care
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists discuss the importance of multidisciplinary care in managing generalized pustular psoriasis (GPP), including collaboration between dermatologists and other specialists, and explore strategies for addressing the psychosocial aspects of treatment to improve overall patient outcomes.

Older Treatment Approaches to GPP Management
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists discuss the general treatment approach for generalized pustular psoriasis (GPP) prior to the availability of FDA-approved agents with specific indications, examining how these treatments aligned with patient goals and identifying the unmet needs that remained in managing the disease.

GPP Pathogenesis and Treatment Goals
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists discuss recent advances in understanding the pathogenesis of generalized pustular psoriasis (GPP) and how these insights have influenced the approach to and management of the disease. They also outline their immediate and long-term treatment goals for patients with GPP, focusing on symptom control and long-term disease management.

Challenges for Making a Timely GPP Diagnosis
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists discuss the biggest challenges dermatologists face in diagnosing generalized pustular psoriasis (GPP), focusing on the heterogeneity of patient presentations and how this complicates the diagnosis. They also explore how the relative rarity of GPP, compared with other psoriatic conditions, contributes to delays in diagnosis and treatment. They also examine the impact of misdiagnosis or delayed diagnosis on patient outcomes.

Approaches to Diagnosing GPP and Distinguishing It From Other Psoriatic Conditions
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists discuss their typical approach to diagnosing generalized pustular psoriasis (GPP), including key clinical features and how they distinguish GPP from other psoriatic conditions such as plaque psoriasis based on presentation and diagnostic criteria.

Impact of GPP Triggers and Flares on a Patient’s Physical and Mental Health
ByAaron Farberg, MD, FAAD ,Harrison Nguyen, MD, MBA, MPH, FAAD ,Boni Elewski, MD, FAAD ,Johann Gudjonsson, MD, PhD, FAAD Panelists discuss the physical and mental health challenges of generalized pustular psoriasis (GPP), common flare triggers, the varying severity of flares, and the importance of timely treatment to prevent severe complications.
