Development and characterization of LQ080, a novel extended half-life bispecific TL1A/IL-23 p19 single domain antibody for the treatment of IBD
(ECCO-IBD 2025)
- "The TL1A/IL-23 p19 biparatropic sdAb, LQ080, showed better IFNγ secretion inhibition than RVT-3101 and PRA023, and better inhibition of mouse IL-17 induction than Risankizumab and Guselkumab. No large immune complex formation when mixed with TL1A and IL-23 would make LQ080 safer when administrated by SC route. Overall, LQ080 is a promising TL1A/IL-23 p19 sdAb for IBD treatment."

AI-guided generation and development of HXN-1001, a highly potent and half-life extended anti-TL1A antibody
(ECCO-IBD 2025)
- "In a DSS-induced colitis model in transgenic mice, HXN-1001 demonstrated superior anti-inflammatory effects compared to RVT-3101, MK-7240, and the α4β7 antibody Vedolizumab. In an IMQ-induced psoriasis model, HXN-1001 exhibited better therapeutic effects than the marketed anti-IL-23 monoclonal antibody Risankizumab...It has strong potential to enhance clinical efficacy and dosing convenience. HXN-1001 is anticipated to enter clinical development in Q2 2025."

Engineering and Development of a Novel Bispecific Antibody Targeting IL-23 and TL1A
(ECCO-IBD 2025)
- "Results HXN-1003 features a tetravalent structure, with the anti-IL23 arm specifically binds to the p19 subunit of IL23, demonstrating superior affinity and blocking activity compared to benchmark Risankizumab. For TL1A, HXN-1003 binds to both the TL1A trimer and monomer with sub-nanomolar affinity, exhibiting similar blocking activity to its parent antibody HXN-1001 and RVT-3101...Conclusion HXN-1003 simultaneously blocks IL23 and TL1A, with each arm exhibiting activity comparable to the parent monoclonal antibodies. It has demonstrated synergistic/additive therapeutic effects in both in vitro and in vivo experiments, highlighting its potential to enhance clinical efficacy and benefit autoimmune patients in multiple clinical settings."

(ACG 2024)
- P2 | "A total of 245 patients received ≥1 dose of RO7790121; 228 patients completed induction and 224 entered maintenance. At week 14, a greater proportion of patients across all treatment doses achieved remission vs PBO by both tMS (p >0.05) and mMS (nominal p < 0.05), sustained through week 56 (Table). Patients receiving any dose of RO7790121 showed greater endoscopic improvement vs PBO at weeks 14 and 56 (Table)."

CHARACTERIZATION OF TWO NOVEL EXTENDED HALF-LIFE MONOCLONAL ANTIBODY DRUG CANDIDATES TARGETING TL1A FOR THE TREATMENT OF IBD
(UEGW 2024)
- "Aims & SPY002-091 and SPY002-072 were evaluated in multiple in vitro and ex vivo assays and compared to other anti-TL1A mAbs in clinical development (MK-7240, RG6631, and TEV-48574). We have characterized two anti-TL1A antibodies that exhibit high selectivity and affinity for TL1A, demonstrate effective blockade of the TL1A interaction with DR3, and potently inhibit downstream cellular signaling. With an extended half-life observed in NHP, both SPY002-091 and SPY002-072 demonstrate therapeutic potential for effective and safe treatment of CD and UC with the advantage of infrequent SC dosing. Further preclinical and clinical studies are warranted to demonstrate this potential."

DISCOVERY AND CHARACTERIZATION OF A NOVEL HIGH-AFFINITY ANTI-TL1A MONOCLONAL ANTIBODY WITH EXTENDED HALF-LIFE FOR THE TREATMENT OF INFLAMMATORY BOWEL DISEASE
(UEGW 2024)
- "Select clinical candidate antibodies were further compared to clinical-stage anti-TL1A mAbs PRA023/MK-7240/tulisokibart, RVT-3101/RG6631, and TEV-48574. The clinical candidate antibodies bind with high affinity and specificity to TL1A and demonstrate potent blockade of TL1A-mediated DR3 receptor signaling. In human FcRn knock-in mice and in cynomolgus monkeys, these antibodies show an extended half-life consistent with FDA-approved antibodies using the XtendTM technology. These data demonstrate the therapeutic potential of the clinical candidate antibodies in the treatment of TL1A-mediated diseases such as ulcerative colitis and Crohn’s disease - with the advantage of infrequent subcutaneous dosing."
