Safety and efficacy of trifluridine/tipiracil +/- bevacizumab plus XB2001 (anti-IL-1α antibody): a single-center phase 1 trial. (PubMed, Signal Transduct Target Ther) - P1/2 | "XB2001, a fully human monoclonal antibody neutralizing IL-1α, was evaluated for safety and preliminary efficacy with trifluridine/tipiracil (FTD/TPI) and bevacizumab in metastatic colorectal cancer patients previously treated with oxaliplatin- and irinotecan-based chemotherapies. High intratumoral IL-1α expression at baseline and CD8/PD-L1 infiltration are associated with a better progression-free survival. The combination of XB2001 with FTD/TPI and bevacizumab is feasible and safe, and showed encouraging clinical activity in chemotherapy-resistant mCRC."

XBiotech Pauses Rheumatology program (GlobeNewswire) - P2 | N=210 | NCT05363891 | Sponsor: XBiotech, Inc. | "XBiotech...announced today data that it is halting its clinical program in rheumatological disease while it seeks to understand the outcome from its recently completed Phase II, Double-Blind, Placebo-Controlled, Randomized study in Rheumatoid Arthritis. The Phase II study failed to meet its primary endpoint amid substantial irregularities that make unequivocal interpretation of the findings difficult. XBiotech was planning launch of additional studies in arthritis as well as other areas of rheumatology, including ankylosing spondylitis, which are now on hold while recent findings are evaluated...Although the study did not meet efficacy endpoints, discrepancies found during data analysis suggest caution in interpreting results."

Phase I dose-escalation study of trifluridine/tipiracil plus XB2001 and bevacizumab in chemorefractory advanced colorectal cancer: The TASKIN study (ESMO-GI 2024) - P1/2 | "This supports testing the combination of TAS-102 plus XB2001 (an IL-1α monoclonal antibody). In the phase 1/2 TASKIN study (NCT05201352), patients (pts) with chemorefractory metastatic CC after failure of oxaliplatin, irinotecan, and fluoropyrimidine were enrolled and received XB2001 from 250 mg to 1000 mg every 2 weeks plus FTD-TPI 35 mg/m2. FTD-TPI plus XB2001 and bevacizumab demonstrated acceptable safety with promising efficacy in chemorefractory metastatic CC. The study continues as a randomized phase 2 study comparing FTD-TPI and bevacizumab with or without XB2001."

XBiotech Results from Randomized Double-Blinded Phase 1/2 Study Suggest Potential Breakthrough Treatment for Advanced Pancreatic Cancer (GlobeNewswire) - P1/2 | N=69 | 1-BETTER (NCT04825288) | Sponsor: XBiotech, Inc. | "The Phase 1 portion was a dose escalation study in metastatic pancreatic cancer patients to determine if dose limiting toxicities (DLTs) occurred in combination with the ON+5FU+LV regimen in second- or third-line setting. DLTs were not expected with Natrunix and none were seen....The primary endpoint for the Phase 2 study was to assess the safety and tolerability of Natrunix when used with the ON+5FU+LV combination. Overall, there were fewer adverse events (AEs) of any kind during the 24-week treatment period for the Natrunix arm compared to placebo (297 vs 336), with markedly fewer events in specific categories of adverse events during that time."

IL-1 Mediates Tissue-Specific Inflammation and Severe Respiratory Failure in COVID-19. (PubMed, J Innate Immun) - "Mice were treated with one anti-S100A8/A9 antibody, the IL-1 receptor antagonist anakinra or vehicle, and Flo1-2a anti-murine anti-IL-1α monoclonal antibody or the specific antihuman IL-1α antibody XB2001 or isotype controls. Circulating alarmins, specifically calprotectin, of critically ill COVID-19 patients induces tissue-specific inflammatory responses through an IL-1-mediated mechanism. This could be attenuated through inhibition of IL-1 receptor or of IL-1α."
