Intervention model description: This is a multi-center, Phase 2/3 Study to evaluate the efficacy and safety of nasally administered CPM in subjects with symptomatic COVID-19 with a positive PCR test.
Primary purpose: TREATMENT

Brief summary: The goal of this clinical trial is to examine the effectiveness of intranasal-administered Chlorpheniramine Maleate in COVID-19-positive participants as part of early treatment for COVID-19. The main questions it aims to answer are:

* To assess the efficacy of nasal spray with Chlorpheniramine (0.4%) for improving clinical recovery in COVID-19 patients.
* To assess the efficacy, safety, and tolerability of nasal spray with Chlorpheniramine (0.4%) as an adjunct to the standard of care in reducing hospitalizations and improving clinical recovery in adult patients with mild COVID-19.

Detailed description: The main goal of the present study is to examine the effectiveness of CPM intranasal spray as part of early treatment for COVID-19. The study will test the hypothesis that intranasal CPM would accelerate clinical recovery, particularly the alleviation of sensory symptoms and URS, in patients with COVID-19.
