Introduction to Nepafenac
Nepafenac, a nonsteroidal anti-inflammatory drug (NSAID), is widely used in ophthalmology for the treatment of pain and inflammation associated with cataract surgery and other ocular conditions. Here, we will delve into the recent clinical trial results, market analysis, and future projections for this drug.
Clinical Trial Results
Phase II Clinical Trial by Mati Therapeutics
A significant Phase II clinical trial conducted by Mati Therapeutics evaluated the safety and efficacy of nepafenac delivered through their proprietary Evolute® sustained ocular punctal plug drug delivery platform. This multi-center, randomized, masked trial involved 56 patients undergoing cataract surgery, comparing nepafenac Evolute® with a placebo.
-
Pain Reduction: The trial showed that nepafenac Evolute® significantly reduced post-operative pain. At Day 3, 70% of patients treated with nepafenac Evolute® experienced no pain, compared to 38% in the placebo group (p value = 0.032). Moreover, 42% of patients using nepafenac Evolute® were pain-free throughout the trial period, whereas none in the placebo group achieved this (p value < 0.001)[1].
-
Inflammation Control: The treatment also demonstrated a statistically significant difference in post-operative inflammation, as measured by cell and flare scores, particularly for subjects with none-to-mild anterior chamber cells at Day 3[1].
-
Visual Acuity: The trial highlighted improved clinical outcomes, including statistically significant improvements in best corrected and uncorrected visual acuity scores at Day 14. For instance, 65% of subjects treated with nepafenac Evolute® achieved 20/20 or better best corrected visual acuity, compared to 29% for those treated with placebo (p = 0.021)[1].
Other Clinical Trials
Other clinical trials have also compared nepafenac with other NSAIDs and placebos. For example, a European study (EudraCT number 2005-002647-35) compared nepafenac 0.1% eye drops with ketorolac trometamol 0.5% eye drops and a placebo for the prevention and treatment of ocular inflammation and pain associated with cataract surgery. This study further validated the efficacy of nepafenac in managing post-surgical ocular discomfort and inflammation[4].
