Study to Evaluate Benefits & Safety of Endourage Formula C™ Oral Drops in People With Post-Acute COVID-19 Syndrome.

Study Overview
=================
Brief Summary
-----------------
This study will explore the contribution of CBD oral drops in persons experiencing symptoms of Post Acute COVID Syndrome or PACS.

Detailed Description
-----------------
At present, conventional medical and rehabilitation therapies have not consistently been effective for people with PACS, and in fact some symptoms have been observed to worsen over time. This inconsistency in clinical response has created a need for alternative treatment options to be explored. CBD presents a novel approach that warrants further investigation. After review and approval by an Institutional Review Board (IRB), potential study participants will be recruited from on-line support groups who have identified themselves as persons experiencing post-acute COVID-19 syndrome also known as (long-haulers syndrome). The study will be registered on the www.clincaltrials.gov website and will accept referrals from targeted clinics who refer their patients to the investigational site listed and individuals can also self-refer to the study center team. Subjects will be evaluated weekly using telemedicine procedures. At completion of study, there will be a 7-day and 14-day follow up telemedicine visit to assess for continued benefit and/or re-emergence of symptoms/relapse.

Design Details

Primary Purpose: Other
Allocation: Randomized
Intervention Model: Crossover Assignment
Interventional Model Description: A total of 60 (sixty) participants who meet inclusion and exclusion criteria will be randomized and enrolled in a 1:1 ratio of study product (Formula C) vs. placebo. Group 1: 30 participants will be randomized to masked active study product (Formula C) for 28-days; they will continue to the open label extension phase (with commercially available product for an additional 28-days when they will receive commercially available product. Group 2: 30 participants will be randomized to placebo for 28-days; they will roll-over to the open label extension phase of study product (Formula C) for an additional 28-days when they will receive commercially available product. At the completion of the treatment period, the participants will be followed for 14-days.
Masking: Single

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Reduction in patient reported outcomes measures on the Patient Reported Outcomes Measurement Information System (PROMIS ®) assessment tools. | PROMIS® is a set of patient-centered instruments used to measure various patient reported outcomes. Measures are scored on the T-score metric of which 50 is the mean of a relevant baseline population with 10 being the standard deviation of that population. A score of 40 is one stndard deviation less than and a score of 60 is one standard deviation greater than the mean of the baseline or reference population. High scores suggest more of what is being measured (e.g., more fatigue, more shortness of breath) and a lower score suggest improvement in symptoms or complaints assessed depending on symptom or complaint being measured. | 56-days (designated time points) | 
| PATIENT GLOBAL IMPRESSION OF CHANGE (PGIC) | This scale evaluates various aspects of patients' health and assesses if there has been an improvement or decline in clinical status. Scale associated with subjective responses range 1-7 (from no change or a one through a great deal better and considerable improvement that has made all the difference or a seven), higher ratings indicate improved sympomtoms (responders) versus those reporting lower scores suggesting no change or a worsening of their condition (non-responders). | 56-days (designated time points) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Study product related adverse events and side effects. | Daily diary entries and clinical interview at scheduled visit; the number of participants with treatment related events as measured by grading scale of the Common Terminology Criteria for Adverse Events (CTCAE), grade 1-IV (one through four) and using descriptor terms, mild, moderate, severe. Additionally, any adverse event meeting serious adverse event criteria will be collected and reported. Frequency summary tables of all adverse events/serious adverse events will be tabulated and reported. | 56-days (designated time points) |
