Evaluation of the Efficacy of Respicure® (Resveratrol / Quercetin) in the Management of Respiratory Conditions Including Asthma,COPD and Long COVID.

Study Overview
=================
Brief Summary
-----------------
Interventional, Prospective, National, Multicentre, Randomised, Open-label, Controlled Clinical Study Comparing Two Parallel Groups, One Control Arm (Standard Treatment) Versus Intervention Arm (Standard Treatment + Study Product) Evaluating the Efficacy of Respicure® 0.38% /0.38% (Resveratrol / Quercetin) Phytotherapy Product From BEKER Laboratories as an add-on Treatment in the Management of Respiratory Conditions Including Asthma (Partially Controlled),COPD (Stage A, B, C and D) and long COVID in Algerian Adult Patients .

Detailed Description
-----------------
This is an interventional, prospective, national, multicenteric, randomized, open-label, controlled clinical study comparing two arms: Control arm taking the standard of care Versus Intervention arm (standard of care + Respicure®). A total of 480 patients (160 in each group of pathology i.e Asthme, COPD and long COVID, distributed through 8 centers resulting in 20 patients/center for each group of pathology). The administration of the study product is by randomaisation.The data will be collected during 5 visits for the two arms as following: Visit V1 on D0: inclusion, signature of informed consent and implementation of the RESPIRE DZ protocol with delivery to patients of a one-month supply of Respicure® for the intervention arm, Intermediary visit on D15: face-to-face and/or by telephone to assess safety after the use of Respicure® for the intervention arm. Visit V2 on D30: follow-up visit with delivery to patients of a one-month supply of Respicure® for the intervention arm, Visit V3 on D60: follow-up visit with delivery to patients of a one-month supply of Respicure® for the intervention arm, Visit V4 at D90:follow-up visit at the end of the use of the study product, Visit V5 at D180: follow-up and end-of-study visit.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of asthma symptoms in partially controlled patients . | The assessment of asthma management will be based on: 1. Improvement in symptoms measured at baseline and during the follow-up period and results will be compared to those of the control group to determine asthma control using the following criteria: Daytime symptoms at most twice a week, No nocturnal awakenings, Need for rescue medication at most twice a week, No limitation of activities. | Change from Baseline at 3 months | 
| Change of COPD symptoms in patients with stage A, B, C or D. | The assessment of reduction in symptoms will be be compared to those of the control group and will be based on reducing CAT scoring COPD assessment test to be less than 10. | Change from Baseline at 3 months | 
| Change of COPD symptoms in patients with stage A, B, C or D. | The assessment of reduction in symptoms will be based on reducing mMRC scoring modified Medical Research Council where 0 being the best and 4 being the worst. | Change from Baseline at 3 months. | 
| Change of respiratory symptoms related to long COVID. | The assessment of the respiratory symptoms linked to long COVID will be based on the reduction in dyspnea and cough by measuring m mMRC scoring modified Medical Research Council where 0 being the best and 4 being the worst. | Change from Baseline at 3 months | 
| Change of respiratory symptoms related to long COVID. | The assessment of the respiratory symptoms linked to long COVID will be based on: - Improvement of Blood oxygen saturation. | Change from Baseline at 3 months |

| Change of CAT scoring for Asthma patients | Improvement of CAT scoring (Asthma control test) more than 20. | Change from Baseline at 3 months | 
| Change of Respiratory function for Asthma patients | Evaluation of respiratory function by spirometry to detect Variation of PEF (Peak expiratory flow) compared to baseline (in %) | Change from Baseline at 3 months | 
| Change of Respiratory function for Asthma patients | Evaluation of respiratory function by spirometry to detect: Improved FEV1/FVC ratio (Forced expiratory volume in one second/ Forced vital capacity) compared to baseline (in %) | Change from Baseline at 3 months |
