Chlorpheniramine Nasal Spray to Accelerate COVID-19 Clinical Recovery in an Outpatient Setting: ACCROS-III

Phase 2

Completed

• Conditions: COVID-19; COVID-19 Pandemic; Coronavirus Infections; Coronavirus Disease 2019; Symptoms and Signs
• Interventions: Combination Product: Chlorpheniramine Maleate 0.4% Nasal Spray; Combination Product: Placebo

• Registration Number: NCT05886829
• Lead Sponsor: Dr. Ferrer BioPharma

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.

Primary Outcome Measures

Name	Time	Method
Visual Analog Scale (VAS)	Baseline through day 7	Change from baseline visual analog scale (VAS) to day 7; The VAS is a quantitative method that evaluates the severity of symptoms on a scale of 1-10 (no signs to worst symptoms). A 10 cm line is used to grade the severity of symptoms from "no symptoms" (0 cm) to "the highest level of symptoms" (10 cm).
Daily symptoms score (DSS)	Baseline through day 7	Change from baseline daily symptoms score (DSS) to day 7; The DSS is an instrument comprised of a four-point severity rating scale ranging from 0 to 3.; 0 = no symptoms; 1. = mild symptoms; 2. = moderate symptoms; 3. = severe symptoms.

Secondary Outcome Measures

Name	Time	Method
Hospitalization	Baseline through Day 28	The proportion of Hospitalizations
Mortality	Baseline through Day 28	Rate of mortality
The proportion of subjects reporting olfactory function	Baseline through Day 7	Olfactory function reported on a four-point severity rating scale ranging from 0 to 3.; 0-normal; 1. slightly damaged; 2. moderately damaged; 3. away
The proportion of subjects reporting the presence of upper respiratory symptoms	Baseline through Day 7	The proportion of subjects reporting the presence of upper respiratory symptoms (anosmia, ageusia, cough, and nasal congestion) using a yes or no scale.; Yes- Present No- No symptoms present
