Edesa Biotech reported additional positive Phase 3 results for its anti-TLR4 antibody paridiprubart in a 278-patient study. Across the full population, paridiprubart cut adjusted 28-day mortality to 24% versus 33% on placebo, a 27% relative risk reduction with strong statistical significance (p<0.001).
In a milder, 174-patient non-IMV subgroup, paridiprubart plus standard of care reduced adjusted 28-day mortality to 15% from 23%, a 35% relative risk reduction (p<0.005). Patients on paridiprubart also showed higher rates of clinical improvement by Day 28, and safety, adverse events and discontinuations were low and similar to placebo.
More than 400 patients have now received paridiprubart. Based partly on these results, Edesa has filed U.S. provisional patents covering use of paridiprubart in sepsis, acute kidney injury and pneumonia, adding to core composition-of-matter patents that extend into the 2030s. The drug is also being tested in a separate, government-funded ARDS study with enrollment of about 200 subjects for the company cohort.
