Mesoglycan's anti-edematous, antithrombotic, and profibrinolytic actions suggest it may relieve Grade I–III HD symptoms, improve HRQoL, and have low AEs compared to placebo. The trial uses placebo to assess mesoglycan's benefits clearly. Patients take two mesoglycan capsules daily for 5 days, then one capsule for 35 days. Compliance is monitored via returned blister packs. Concomitant analgesics and stool softeners are allowed. Primary outcomes measure HDSS change from baseline to day 40, while secondary outcomes assess HRQoL, safety, fecal continence, bleeding, analgesic use, and pain. The trial aims to enroll 50 patients by October 2024.
