clinical trial to compare the safety and efficacy of nanodrop®

Conditions: Dry Eye

Summary: study design: phase i-ii clinical trial, comparative, non-inferiority with active control, parallel groups, double blind with randomisation. safety analysis when completing the visits of the first 12 subjects of the nanodrop® group, if there are less than 20% of unexpected events (ea), related to the research product, recruitment is continued until the sample is completed for efficacy analysis objectives security: evaluate the safety of the ophthalmic application of nanodrop® by quantifying the incidence of unexpected adverse events (ea) related to the research product (pi). effectiveness: demonstrate the non-inferiority of nanodrop® compared to systane® balance, in the efficacy of the treatment of patients with dry eye, by means of the ocular surface disease index (osdi). hypothesis security: h0 = nanodrop® is safe in its ophthalmic application as it presents an incidence of unexpected adverse events related to the research drug, less than 20% of the population of nanodrop® safety group. h1 = nanodrop® is not safe in its ophthalmic application, as it presents an incidence of unexpected adverse events related to the research drug, exceeding 20% of the population of nanodrop® safety group. effectiveness: h0 = nanodrop® is lower than systane® balance by more than 5 points in the osdi test score. h1 = nanodrop® is lower than systane® balance by 5 points or less in the osdi test score. number of subjects: n = 126 evaluable subjects 63 evaluable subjects per group (both eyes). main inclusion criteria: dry eye diagnosis duration of intervention treatment: 28 days approximate duration of the subject in the study: 35 days
