According to the Zhitong Finance APP, Grandpharma (00512) recently announced that the group has completed Phase III clinical trials in China for the glucocorticoid nanosuspension eye drops GPN00833 used for post-operative ophthalmic anti-inflammatory and analgesic purposes, achieving the clinical endpoints successfully. This marks another significant milestone for the group in the otorhinolaryngology field and ophthalmic direction.
It is reported that GPN00833 is an anti-inflammatory and analgesic glucocorticoid nanosuspension eye drops, with its main active ingredient chlorobutanol acetate being a potent glucocorticoid with highly effective local anti-inflammatory activity and strong vasoconstrictor effects. Simultaneously, its unique nanosuspension process effectively addresses the low solubility of steroid products leading to low bioavailability and safety risks. This product was approved in April 2023 in China to conduct a multicenter, randomized, double-blind, placebo-controlled, parallel-group Phase III clinical study, enrolling a total of 255 patients who underwent cataract surgery, assigned in a 2:1 ratio to the study drug group and placebo group, evaluating the effectiveness and safety of GPN00833 in treating postoperative inflammation and pain after cataract surgery in the Chinese population. The primary clinical endpoint of this study is the percentage of patients with zero anterior chamber cell count (no inflammation) between the 8th and 15th days after cataract surgery, with the secondary endpoint being the percentage of patients with zero eye pain grade between the 4th and 15th days after surgery.
The study results show that in terms of anti-inflammatory effects, the percentage of patients with zero anterior chamber cell count between the 8th and 15th days after surgery in the study drug group was significantly higher compared to the placebo group, at 31.8% and 20.0% respectively, demonstrating statistical significance and clinical relevance. For analgesic effects, the percentage of patients with zero eye pain grade between the 4th and 15th days after surgery was significantly higher in the study drug group compared to the placebo group, at 91.2% and 55.3% respectively, also showing statistical significance and clinical relevance. Additionally, the product demonstrated good safety, tolerability, and pharmacokinetic characteristics as expected. Overall analysis indicates that GPN00833 is significantly more effective than the placebo in treating postoperative inflammation and pain after cataract surgery, with good safety profile. In terms of international registrations, the product obtained approval from the United States Food and Drug Administration (FDA) in March 2024.
