ReAlta Life Sciences Presents Promising Phase 2 Data on Pegtarazimod for Acute GvHD at ASH 2025
ReAlta Life Sciences, a clinical-stage biopharmaceutical company, has announced interim results from its Phase 2 clinical trial of pegtarazimod (RLS-0071) for treating steroid-refractory acute graft-versus-host disease (aGvHD). The data, presented at the 67th American Society of Hematology (ASH) Annual Meeting, highlight significant clinical improvements in patients with lower gastrointestinal aGvHD. The study, which is an open-label, prospective, dose-escalation trial, showed that all six patients in the treatment optimization cohort experienced clinical improvement, with a median 68% reduction in plasma myeloperoxidase levels, indicating modulation of inflammatory mechanisms. The safety profile was favorable, with no dose-limiting toxicities or serious adverse events attributed to the drug.
