Bristol Myers Squibb have announced two-year results from the POETYK PSO long-term extension (LTE) trial demonstrating durable efficacy and a consistent safety profile with deucravacitinib treatment in adult patients with moderate to severe plaque psoriasis.

Clinical efficacy was maintained through up to two years of deucravacitinib treatment, with response rates at Week 60 in the LTE of 77.7% and 58.7% for Psoriasis Area and Severity Index (PASI) 75 and static Physicians Global Assessment (sPGA) 0/1 (clear/almost clear skin), respectively.
“Plaque psoriasis is a chronic, systemic immune-mediated disease associated with multiple serious comorbidities, and there remains a strong unmet need for new treatments, particularly oral medicines, as many patients are undertreated or are dissatisfied with current options,” said Professor Richard B. Warren, Consultant Dermatologist, Salford Royal Hospital, part of Northern Care Alliance NHS Foundation Trust and Professor at The University of Manchester. “Long-term research showing durable efficacy, in addition to a well understood safety profile, is critical for clinicians and patients making treatment decisions, and these new two-year data underscore the potential of deucravacitinib to be an important new oral treatment option for people living with moderate to severe plaque psoriasis who require systemic therapy.”
The overall safety profile of deucravacitinib observed through two years spans 2,482 patient years of treatment and was consistent with that observed in the previously presented pivotal Phase 3 POETYK PSO-1 and POETYK PSO-2 trials. Adverse events (AEs) continued to be predominantly of mild or moderate severity, with the most common AEs continuing to be nasopharyngitis, upper respiratory tract infection and headache. Serious AEs and AEs leading to discontinuation remained low for up to two years, and no emerging safety signals were observed. With additional follow-up in the LTE trial, which coincided with the peak of the COVID-19 pandemic, there was an increased number of reported COVID-19 infections compared to the POETYK PSO-1 and POETYK PSO-2 trials; however, deucravacitinib treatment did not increase the risk or severity of COVID-19 infection. Overall incidence rates of COVID-19 infection and COVID-19-related hospitalization and death in the LTE trial were consistent with background epidemiologic rates. Through two years, no new trends or clinically meaningful changes from baseline in laboratory values, including hematology, chemistry and lipid parameters, were observed.
“At Bristol Myers Squibb, our pioneering research is leading to the potential for novel, well-tolerated treatment options for individuals impacted by serious immune-mediated diseases like psoriasis. These long-term follow up results add to the growing body of evidence for deucravacitinib, a first-in-class, oral, selective allosteric TYK2 inhibitor with a unique mechanism of action, reinforcing its potential to offer patients with moderate to severe plaque psoriasis an oral treatment option that addresses current gaps in care,” said Jonathan Sadeh, MD, MSc, senior vice president of Immunology and Fibrosis Development, Bristol Myers Squibb.
Bristol Myers Squibb thanks the patients and investigators involved in the POETYK PSO clinical trial program.
About Deucravacitinib
Deucravacitinib (pronounced doo-krav-a-sih-ti-nib) is an oral, selective allosteric tyrosine kinase 2 (TYK2) inhibitor with a unique mechanism of action, representing a new class of small molecules. It is the first and only selective TYK2 inhibitor in clinical studies across multiple immune-mediated diseases. Bristol Myers Squibb scientists designed deucravacitinib to selectively target TYK2, thereby inhibiting signaling of interleukin (IL)-23, IL-12 and Type 1 interferons (IFN), key cytokines involved in the pathogenesis of multiple immune-mediated diseases. Deucravacitinib achieves a high degree of selectivity by binding to the regulatory domain of TYK2, resulting in allosteric inhibition of TYK2 and its downstream functions. Deucravacitinib selectively inhibits TYK2 at physiologically relevant concentrations. At therapeutic doses, deucravacitinib does not inhibit JAK1, JAK2 or JAK3.
Deucravacitinib is being evaluated in global clinical trials in multiple immune-mediated diseases, including psoriasis, psoriatic arthritis, lupus and inflammatory bowel diseases. Deucravacitinib is under regulatory review with global health authorities, including the U.S. Food and Drug Administration (FDA) and European Medical Association (EMA) for the treatment of moderate to severe plaque psoriasis and by Japan's Ministry of Health, Labour and Welfare for the treatment of adults with moderate to severe plaque psoriasis, pustular psoriasis and erythrodermic psoriasis.
