- |||||||||| EFFICACY AND SAFETY OF ADVANCED MEDICAL TREATMENTS FOR INDUCTION OF REMISSION IN CROHN'S DISEASE: A SYSTEMATIC REVIEW AND NETWORK META-ANALYSIS (Hall A) - Mar 14, 2024 - Abstract #DDW2024DDW_4909;
There was moderate certainty of evidence for combination of ADA and azathioprine (AZA) (RR 3.1, 95%CI [2.0-4.8]; risk difference [RD]: 40.1%), IFX+AZA (RR 2.5, 95%CI [1.7-3.8]; RD: 28.9%), ADA (RR 2.5, 95%CI [1.8-3.5]; RD:28.5%), and UST (RR 2.0 95%CI, [1.6-2.5]; RD: 19.2%) in induction of clinical remission compared to placebo...Conclusion On network meta-analysis, combination of anti-TNFs and immunomodulators followed by anti-TNF monotherapy had large effect size with moderate certainty for the induction of clinical remission. More novel therapies appear to have examples of similarly important effect sizes, but are currently limited due to the imprecision of the limited evidence base at present and future research should target these therapies in study

ORAL IL-23R ANTAGONIST MINIPROTEIN MB1 IS AS EFFECTIVE AS GUSELKUMAB IN A PRECLINICAL MODEL OF COLITIS (Hall A) - Mar 14, 2024 - Abstract #DDW2024DDW_3189; This work demonstrates for the first time that de novo designed miniproteins can be administered orally and reach a therapeutic target past the gut epithelial barrier. With very high potency, gut stability, and straightforward manufacturability, de novo designed minibinders are a promising new modality for orally delivered biologics.

DEVELOPMENT OF A CROHN'S DISEASE MOLECULAR ACTIVITY SCORE TO IDENTIFY REGION-SPECIFIC CHRONICALLY INFLAMED AND NON-INFLAMED PROCESSES (Hall A) - Mar 14, 2024 - Abstract #DDW2024DDW_3185; P2/3 Application of the MAS to identify inflamed tissue enabled identification of key immune and inflammatory related processes across the ileum and colon that were associated with the IL-23 pathway, and baseline regional endoscopic and histologic severity. By identifying inflamed baseline samples, molecular changes associated with treatment can be more accurately defined in future analyses to better understand regional heterogeneity in CD.

The Efficacy and Safety of Switching From Different Biologics To Interleukin-23 Inhibitors: A Systematic Review () - Feb 20, 2024 - Abstract #AAD2024AAD_3020; Adverse events during IL-23 treatment were uncommon (13%, 115/870) with the most common adverse event being infection in 8.0% (70/870) of patients. Switching to IL-23 inhibitors from other biologics generally results in favorable outcomes with minimal adverse events, supporting their potential as effective alternatives in psoriasis treatment.

VISIBLE: Clearance and Symptom Improvement With Guselkumab at Week 16 in Skin of Color Participants With Moderate-to-Severe Plaque Psoriasis (San Diego Convention Center (Upper Level, Sails Pavilion, Poster Center 1)) - Feb 20, 2024 - Abstract #AAD2024AAD_3013; Switching to IL-23 inhibitors from other biologics generally results in favorable outcomes with minimal adverse events, supporting their potential as effective alternatives in psoriasis treatment. After 3 doses of guselkumab, the majority of participants with moderate-to-severe plaque psoriasis achieved significantly clearer skin and reported clinically meaningful improvement in psoriasis symptoms.
- |||||||||| Comparative Effectiveness of Biologic Classes in Clinical Practice: Month 12 Outcomes from the International Observational Psoriasis Study of Health Outcomes (PSoHO) (San Diego Convention Center (Upper Level, Sails Pavilion, Poster Center 1)) - Feb 20, 2024 - Abstract #AAD2024AAD_2944;
The adjusted ORs (95% CIs) of achieving PASI100 (M12) for the IL-17A/RA cohort, was 1.3 (1.02,1.71), 2.0 (1.24,2.61) and 0.9 (0.77,1.14) compared to TNF-?, IL-12/23 p40, and IL-23 p19 cohorts respectively. This analysis highlighted the short- and long-term effectiveness and durability of anti-IL-17A/RA biologics compared to other biologic classes.

Applications were submitted for PDMAPs associated with risankizumab-rzaa, adalimumab, ixekizumab, guselkumab, secukinumab, apremilast, tildrakizumab-asmn, and brodalumab. There are significant timeliness and enrollment differences across PDMAPs.

Preclinical, Journal: A Novel human IL-23A Overexpressing Mouse Model of Systemic Lupus Erythematosus. (Pubmed Central) - Feb 16, 2024 We have generated and characterized a novel genetic mouse model of SLE, providing proof-of-concept for the etiopathogenic role of hIL-23A. This new model has a normal lifespan and integrates several characteristics of the human disease's complexity and chronicity making it an attractive preclinical tool for studying IL23-dependent pathogenic mechanisms and assessing the efficacy of anti-hIL23A or modeled disease-related therapeutics.
