Overview
The present study is a randomized, placebo-controlled, double-blind, parallel-group clinical study designed to assess the effects of IP in individuals with mild cognitive impairment and Tinnitus as compared to a placebo. Approximately 112 individuals aged between 30 and 75years will be screened. Considering a screen failure of 25%, approximately 84 individuals will be randomized in a ratio of 1:1 to receive either the active or placebo. The study will have at least 64 completed participants i.e. 32 participants in each study arm after accounting for adropout/withdrawal rate of 25% at the end of the study. The intervention and follow up duration for all the study participants will be 90 days.
