COVID-19-IAMA: Assessment of the Clinical Effectiveness of a Herbal Extract (Cretan IAMA) in Patients With Viral Respiratory Infections, Including COVID-19, in Primary Healthcare Settings, and Co-assessment of Its Prophylactic Effect in People Cohabiting With These Patients
Study Details
Study Description
Brief Summary
This single-arm, open-label small interventional proof-of-concept (POC) study study aims:
-
to assess the clinical outcomes of patients exhibiting viral respiratory infection (VRI) symptoms and seeking primary healthcare (PHC) services at the time of the COVID-19 pandemic,
-
to assess the clinical effectiveness of the Cretan IAMA (CAPeo), a herbal extract combination, for these patients, including in terms of symptom resolution (symptom frequency, duration) and intensity), and
-
to investigate its prophylactic effect in terms of transmission prevention for people cohabiting with the patients exhibiting VRI symptoms.

Detailed Description
Cretan IAMA (CAPeo) is an essential oil mixture of three native herbs of Crete (Thymbra capitata (L.) Cav., Salvia fruticosa Mill. and Origanum dictamnus L.), which exhibits remarkable in vitro antiviral activity against Influenza A & B and the Human Rhinovirus HRV-14 strains, decreasing the symptoms of upper respiratory tract viral infections. It has also been proven safe in experimental animals and humans. There is currently a strong unmet medical need for safe and effective therapeutic regimens for patients in ambulatory settings. Given its properties, it was, therefore, deemed both appropriate and urgent to explore its potential in the context of COVID-19 for patients in primary care settings. It was also deemed important to investigate the Cretan IAMA (CAPeo) regarding prophylactic treatment for people coming in close contact with these ambulatory patients.

Outcome Measures
Primary Outcome Measures
- Number of patients with symptom resolution [2 weeks (14 days)]
Number of patients with symptoms recorded at baseline resolving at 2 weeks (14 days) or sooner
- Number of people cohabiting with a patient not developing VRI symptoms [2 weeks (14 days) )]
Number of people cohabiting with a patient who did not develop VRI symptoms (per patient) at 2 weeks (14 days)
Secondary Outcome Measures
- Median time to full symptom resolution [2 weeks (14 days)]
Median time to full symptom resolution, including those emerging after Day 1 adjusted for symptoms emerging after Day 1 (Baseline symptoms)
- Intensity of symptoms [2 weeks (14 days)]
Intensity of symptoms, incl. of those emerging after Day 1 (Baseline symptoms), and adjusted for symptoms emerging after Day 1 (Baseline symptoms), scoring on the seven-point Likert scale based on a questionnaire adapted from the Wisconsin Upper Respiratory System Survey - A seven-point Likert scale allowed recording 131 of reported symptoms starting from 1 (minor) to 2 (very mild) and 3 (mild), 4 (somewhat moderate) and 132 5 (moderate) and culminating to 6 (severe) and 7 (very severe).
- Duration of symptoms [2 weeks (14 days)]
Duration of symptoms, incl. of those emerging after Day 1 (Baseline symptoms) and adjusted for symptoms emerging after Day 1 (Baseline symptoms)
- Number of patients whose symptoms never exceeded a score of 3-4 (mild) [2 weeks (14 days)]
Number of patients whose symptoms never exceeded a score of 3-4 (mild) on the seven-point Likert scale based on a questionnaire adapted from the Wisconsin Upper Respiratory System Survey
- Quality of life (QoL) of patients [2 weeks (14 days)]
EQ-5D-5L measurement of QoL
