What side effects are associated with this type of intervention?

Common treatments for Palmoplantar Pustulosis (PPP) include systemic therapies such as oral retinoids, methotrexate, cyclosporine, and biologics like infliximab and adalimumab. These treatments can have various side effects. Oral retinoids may cause dryness of the skin and mucous membranes, elevated liver enzymes, and lipid abnormalities. Methotrexate can lead to liver toxicity, bone marrow suppression, and gastrointestinal issues. Cyclosporine is associated with nephrotoxicity, hypertension, and increased risk of infections. Biologics like infliximab and adalimumab can cause injection site reactions, increased risk of infections, and potential reactivation of latent tuberculosis. Deucravacitinib, being a selective TYK2 inhibitor, may have a different side effect profile, but further studies are needed to fully understand its safety and efficacy.

What prior FDA approvals exist?

There is limited information on prior FDA approvals specifically for the treatment of Palmoplantar Pustulosis (PPP). However, treatments for PPP often involve biologics and immunomodulatory therapies. Deucravacitinib, a selective TYK2 inhibitor, represents a novel approach in this context. Similar treatments that modulate immune pathways, such as TNF inhibitors, IL-17 inhibitors, and IL-23 inhibitors, have been used for related inflammatory conditions like psoriasis, which shares some pathophysiological features with PPP.

What other types of research exist?

Promising novel alternatives to Deucravacitinib for Palmoplantar Pustulosis patients include the use of hydrocolloid dressings for hand-foot skin reactions induced by kinase inhibitors, which are being studied in a phase 3 trial. Additionally, the combination of topical beta-blockers (timolol) and antibiotic ointments (neomycin/tyrothricin) has shown favorable results in treating drug-induced skin conditions like paronychia and pseudopyogenic granulomas. These treatments could potentially be adapted for PPP management.

Summary

This trial tests a pill called deucravacitinib in adults with severe PPP who haven't responded to other treatments. The medication aims to reduce inflammation and calm the immune system, improving symptoms like redness and swelling. Deucravacitinib has shown efficacy in treating moderate to severe plaque psoriasis.

Who is the study for?

Adults over 18 with a dermatologist-confirmed diagnosis of Palmoplantar Pustulosis (PPP) for at least 6 months, who have not seen results from topical treatments and are candidates for systemic or phototherapy. Participants must have moderate to severe PPP and be willing to stop current PPP treatments except OTC emollients.

What is being tested?

The trial is testing Deucravacitinib, taken daily at a dose of 6 mg for 24 weeks by patients with PPP. The study involves regular visits every four weeks and aims to see how effective this treatment is in managing the condition.

What are the potential side effects?

While specific side effects for Deucravacitinib in this trial aren't listed, common ones may include headaches, nausea, upper respiratory infections, high blood pressure, and potential liver enzyme abnormalities.

Mechanism Of Action

Side Effect Profile

Prior Approvals

Other Research

Deucravacitinib is a selective TYK2 inhibitor that works by blocking the TYK2 enzyme, which is involved in the signaling pathways of several cytokines implicated in inflammatory processes, such as IL-23, IL-12, and Type I interferons. This inhibition reduces the inflammatory response, which is crucial in managing Palmoplantar Pustulosis (PPP), a condition characterized by recurrent pustules and inflammation on the palms and soles. Understanding the mechanism of action is important for PPP patients as it helps in selecting targeted therapies that can effectively reduce symptoms and improve quality of life by addressing the underlying inflammatory pathways.
