Study 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 .

Read the 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.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. 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.

    Time frame: Change from Baseline at 3 months

  2. 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.

    Time frame: Change from Baseline at 3 months

  3. 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.

    Time frame: Change from Baseline at 3 months.

  4. 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.

    Time frame: Change from Baseline at 3 months

  5. 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.

    Time frame: Change from Baseline at 3 months

    Time frame: Change from Baseline at 3 months

  10. Change of Respiratory function for COPD patients

    Evaluation of respiratory function by spirometry to detect variation of FEV (Forced expiratory volume) compared to baseline (in %)
