Expert Perspectives on First-In-Class IL-23 Oral Peptide

 are linked to more frequent exacerbations, poorer asthma control, reduced quality of life, and increased healthcare utilization, independent of lung function severity.

“These data define a more difficult-to-treat asthma phenotype that need to be further investigated, and it might be indicative of the complex interplay between sleep and asthma control, suggesting that treatment for sleep disorders might be an overlooked therapeutic target to reduce the need for intensive asthma therapy and improve outcomes,” wrote study investigator Sebastian Ferri, from IRCCS Humanitas Research Hospital in Italy, and colleagues.

Growing evidence has highlighted a bidirectional relationship between asthma and sleep disorders.

Sleep disturbances, including snoring, frequent awakenings, and daytime sleepiness, are common among patients with asthma and are associated with worse asthma control, increased exacerbations, and impaired quality of life.

The team sought to assess the link between sleep disorders and severe asthma. Using data from the Severe Asthma Network Italy (SANI) registry, this retrospective analysis assessed the prevalence and overall burden of sleep disorders in patients with severe asthma, while also identifying related clinical features, risk factors, and treatable traits.

 Participants were stratified based on the presence or absence of sleep disorders at baseline.

Among 1823 participants with severe asthma, approximately 1 in 4 suffered from a concomitant sleep disorder (26.1%), with 5.5% diagnosed with obstructive sleep apnea (OSA), and 20.5% reported to snore.

“The high prevalence of sleep disorders in our cohort underscores the importance of considering sleep disorders as a comorbidity in patients with severe asthma,” investigators wrote.

Investigators noted that polysomnography data were not available for all patients, which could explain the discrepancy between snoring and OSA. There may be undiagnosed cases of OSA or respiratory-related disorders.

In this study, sleep disorders were more common in overweight patients, which aligns with previous research that found that being overweight is a risk factor for sleep disorders, such as OSA.

Patients with severe asthma and a comorbid sleep disorder also had more frequent rhinitis, chronic rhinosinusitis with and without nasal polyps, gastroesophageal reflux disease (GERD), cardiovascular disease (CVD), and type II diabetes. Additionally, they had greater rates of intranasal corticosteroid use and a greater need for systemic corticosteroids due to increased exacerbation rates.

The study revealed that participants with severe asthma and a comorbid sleep disorder had less severe lung function but worse asthma control and quality of life. These patients also had increased asthma-related hospital admissions and unscheduled medical visits.

“The finding that these patients have worse asthma control and quality of life, despite less severe functional impairment based on FEV1, may indicate that sleep disturbances are an important factor in the overall management of asthma,” investigators wrote.

 “As found by Teodorescu et al, individuals with OSA are 3.6 times as likely to have uncontrolled asthma, [which] leads to a higher number of disease-related hospital admissions and the need [for] non-programmed medical visits.”

Investigators identified several risk factors for sleep disorders in this population: being overweight or having moderate-to-severe rhinitis, chronic rhinosinusitis with and without nasal polyps, GERD, and CVD.

“Considering the overall results of our study, we confirm and strengthen the concept that sleep disorders are a common and relevant clinical feature among patients with severe asthma, and physicians should consider investigating patients’ sleep quality in their daily clinical practice,” investigators concluded. “It is important to consider asthma and sleep disorders as two entities which can influence each other, and only treating properly both we could improve patient quality of life and reduce healthcare burden."

Severe asthma is often accompanied by sleep disorders, which are linked to increased exacerbations, poorer asthma control, and higher healthcare utilization, regardless of lung function severity. This suggests a complex interplay between sleep and asthma, highlighting sleep disorders as a potential therapeutic target. A study using data from the Severe Asthma Network Italy found that 26.1% of patients with severe asthma had sleep disorders, with obesity being a significant risk factor. Addressing sleep disorders in asthma management could improve patient outcomes and reduce healthcare burdens.

Registry data show worse asthma control, more exacerbations, and higher healthcare utilization in patients with severe asthma and a comorbid sleep disorder.

Updates in Remibrutinib from ACAAI 2025

Recent presentations at the American College of Allergy, Asthma & Immunology (ACAAI) 2025 and European Academy of Dermatology and Venereology provided additional insights into the clinical and immunologic effects of remibrutinib in chronic spontaneous urticaria (CSU). In this video Shyam Joshi, MD, assistant professor of medicine in the Section of Allergy and Clinical Immunology at Oregon Health & Science University (OHSU) School of Medicine, breaks down Data demonstrating remibrutinib’s efficacy and safety across both major CSU subtypes—autoallergic (type I) and autoimmune (type IIb).

Analysis of the REMIX trials and additional substudies highlighted remibrutinib’s robust efficacy in patients previously unresponsive to omalizumab, the first FDA-approved biologic for CSU. Even among those who were refractory to this established treatment, remibrutinib achieved high response rates, supporting its utility as a second-line or rescue therapy in difficult-to-treat populations. This finding is of particular clinical significance, given the historical reliance on immunosuppressive agents for patients who failed standard therapies.

The breadth and quality of evidence presented at ACAAI 2025 solidify remibrutinib’s standing as a versatile agent within the CSU therapeutic armamentarium, with its oral administration, rapid onset of action, effective disease modification, and broad applicability positioning it as an integral component of individualized, guideline-driven CSU management. Ongoing updates to clinical practice recommendations are anticipated to further define remibrutinib’s role in routine care.

Takeda has announced positive topline results for a pair of phase 3 randomized, multicenter, double-blind, placebo- and active comparator-controlled studies of zasocitinib (TAK-279), a next-generation, highly selective oral tyrosine kinase 2 (TYK2) inhibitor, in adults with moderate-to-severe plaque psoriasis (PsO).

According to a December 18, 2025, release from the Company, the Latitude studies demonstrated superiority of zasocitinib compared to placebo for the coprimary endpoints of static Physician Global Assessment (sPGA) 0/1 and Psoriasis Area and Severity Index (PASI) 75 at week 16, with a significantly greater PASI 75 response rate observed as early as week 4 and continuing to increase through week 24. Of note, the studies also met all 44 ranked secondary endpoints, including PASI 90, PASI 100 and sPGA 0 against placebo and apremilast.

“People living with psoriasis continue to seek safe, effective and fast-acting oral therapies. These landmark results support zasocitinib’s promise to become a leading oral treatment option that can deliver clear skin for patients with plaque psoriasis,” Christophe Weber, president and chief executive officer at Takeda, said in a statement.

 “This marks the third positive Phase 3 readout from our overarching pipeline this year. Each of these programs – zasocitinib, oveporexton and rusfertide – has potential to transform patient lives, redefine medical practice and deliver significant revenue growth in the future.”

Zasocitinib is an investigational, next-generation, highly selective oral TYK2 inhibitor that maintains 24-hour inhibition of IL-23 as well as other core disease-driving immune pathways. It has > 1-million-fold greater selectivity for TYK2 compared to other JAK enzymes, which could maximize TYK2 inhibition without impacting JAK1, 2 and 3 signaling, based on in vitro data.

Takeda is currently evaluating the safety and efficacy of zasocitinib in a head-to-head study against deucravacitinib in plaque psoriasis and in phase 3 studies in psoriatic arthritis. Additionally, phase 2 studies are ongoing in Crohn’s disease, ulcerative colitis and vitiligo, and being initiated in hidradenitis suppurativa.

The Latitude phase 3 psoriasis studies are global, multicenter, randomized, double-blind, placebo- and active comparator-controlled studies to evaluate the efficacy, safety and tolerability of zasocitinib in adult patients with moderate-to-severe plaque psoriasis. The studies were conducted in 21 countries and enrolled 693 and 1108 participants, respectively.

The co-primary endpoints were the proportion of zasocitinib-treated patients achieving sPGA 0/1 and PASI 75 response compared to placebo at week. Ranked (key) secondary endpoints included comparisons versus placebo at week 16 and apremilast at week 16 and week 24.

As described in the release from Takeda, zasocitinib met the study’s coprimary endpoints for sPGA 0/1 and PASI 75 at week 16, with a significantly greater PASI 75 response rate observed as early as week 4 and continuing to increase through week 24 versus placebo. The studies also met all 44 ranked secondary endpoints.

Zasocitinib was generally well-tolerated, with a safety and tolerability profile consistent with prior studies, including the phase 2b plaque psoriasis study. The most common adverse events through week 24 were upper respiratory tract infection, nasopharyngitis and acne, with no new safety signals identified.

“It is incredibly rewarding and exciting to see our Phase 2 results validated in Phase 3, with more than half of patients treated with zasocitinib achieving clear or almost clear skin (PASI 90) and about 30 percent achieving completely clear skin (PASI 100) at week 16, with response rates continuing to increase through week 24,” Andy Plump, MD, PhD, president of R&D at Takeda, said in a statement.

 “These findings help demonstrate that highly selective inhibition of TYK2, a key mediator of IL-23 and other signaling pathways fundamental to psoriasis, may provide patients with significant reductions in their disease burden, including for many, the possibility of complete skin clearance.”

Takeda detailed plans to present the results at upcoming medical congresses as well as the Company’s intention to submit a New Drug Application with the United States Food and Drug Administration and other regulatory authorities starting in fiscal year 2026.
