Summary

This phase 3 trial tested a new drug called HRS-5965 in 39 adults with paroxysmal nocturnal hemoglobinuria (PNH) who remained anemic even after standard anti-C5 antibody treatment. The study aimed to see if the drug could raise hemoglobin levels without needing blood transfusions. Participants took HRS-5965 capsules for 24 weeks, and researchers measured how many achieved stable hemoglobin levels without transfusions.

What this could lead to

If successful, this could offer a new oral treatment option for PNH patients who still have anemia even after standard anti-C5 antibody therapy.

What could go wrong

This is a small, single-arm trial with only 39 participants, so results may not apply broadly. The drug's safety and effectiveness need confirmation in larger studies.
