S964 A Promising Novel Therapeutic Strategy for Inflammatory Bowel Disease Through Enhanced Efferocytosis and Anti-Inflammatory Mechanisms
Bibliographic record
Abstract
Introduction: Inflammatory bowel disease (IBD) continues to present significant challenges in treatment. Prolonged utilization of existing therapies frequently results in insufficient outcomes, dependency, serious adverse effects, or recurrent disease exacerbations, underlining the urgency for new, innovative treatment strategies. This study explores the potential of a novel drug candidate, NP-011 (C2-deleted MFG-E8), aimed at IBD management through a unique mode of action, with promising therapeutic effectiveness and potential advantages over existing treatment options. Methods: Our hypothesis was that NP-011 functions as a bridging molecule, facilitating the process of efferocytosis. We initially measured the binding affinity of NP-011 to phosphatidylserine (PS) through a radioligand binding assay. Following this, we examined the absorption of fluorescent PS microparticles and apoptotic cells (ACs) by macrophages, and subsequently observed alterations in the expression of HO-1 post absorption of ACs. We then used a DSS-induced UC mouse model to assess the in vivo efficacy of NP-011, focusing on its impact on weight regain, restoration of colon length, reduction of inflammation, and mitigation of necrosis. Results: N P-011 demonstrated strong affinity to phosphatidylserine (PS) and boosted the uptake of PS and apoptotic cells (ACs) by macrophages, leading to an enhanced expression of HO-1. The maximum count of TUNEL-positive cells in mouse colons was observed on day 5 post-exposure to DSS. By strategically administering NP-011 on this pivotal day, we managed to effectively reduce the count of ACs, and lower the concentration of inflammation and necrosis markers in the blood. This resulted in a significant improvement in histopathological assessments. Importantly, NP-011 exceeded the efficacy of its predecessor protein and currently available clinical biologics. Conclusion: NP-011's novel mechanism of action holds potential in addressing the unmet needs in ulcerative colitis treatment. This potential stems from its capacity to facilitate efferocytosis, promoting the cessation of inflammation and steering the cytokine profile to a state of reduced inflammation. Moreover, NP-011 contributes to the repair and reorganization of tissues, staves off the emergence of autoimmunity, and assists in maintaining the balance of the immune system.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
