Outcome Measures

Primary Outcomes (1)

  • 7-point ordinal symptom scale

    Symptom comparison between patients from the treatment vs control group, using an ordinal symptom scale based on the WHO scale. Patients who were hospitalized will be classified according to their worst score over 30 days and non-hospitalized patients according to their score at 30 days.

    30 days

Secondary Outcomes (5)

  • The composite of all-cause mortality and need for mechanical ventilation

Study Arms (2)

Açaí palm berry extract

EXPERIMENTAL

Açaí palm berry extract is a powerful antioxidant with no known side-effects and is widely consumed in Brazil. Açaí palm berry chemical composition has been established and includes several antioxidants - gallic acid, catechin, chlorogenic acid, caffeic acid, p-coumaric acid, epicatechin, orientin, cyanidin-3-0-glucoside, luteolin and apigenin. Orientin is the most concentrated compound (7,96mg/g) and this compound is able to modulate the NLRP3 inflammasome.

Dietary Supplement: Açaí palm berry extract - natural product

Placebo arm

PLACEBO COMPARATOR

This study will be double-blinded and placebo-controlled. To ensure double-blinding, placebo and active compound capsules will be over-encapsulated with DBCAPS® capsules, which were developed with a tamper-evident design to address the clinical trial challenges of testing without bias. These capsules are made of gelatin and have no interaction with bioavailability.

Other: Placebo

Interventions

Patients will be prescribed to take 1 capsule (520mg) of Açaí Palm Berry every 8 hours for a total of 3 capsules a day, during 30 days. Total dose: 1,560mg/day of Açaí Berry extract.

You may qualify if:

  • Adults over 40 years of age; and
  • Mild to moderate symptoms including fever, dry cough, and tiredness; and
  • Tested positive for SARS-Cov-2, via virological diagnosis (PCR), in the last 7 days; and
  • Not hospitalized at the time of randomization, with no limitations on activities; and
  • Willingness to complete questionnaires and records associated with the study.

You may not qualify if:

  • Hospitalized patients at the time of enrollment; or
  • Known allergy to study medication or its non-medicinal ingredients; or
  • Currently taking açai extract or juice; or
  • Chronic severe renal impairment (creatinine clearance \<30 mL/min or on renal replacement therapy); or
  • Pregnant or breastfeeding patients; or
  • Women who are planning to become pregnant during the study; or
  • End-stage cancer or patients in whom imminent demise is anticipated and there is no commitment to active ongoing intervention; or
  • Unable to provide informed consent; or
  • Patients taking antiplatelet/blood-thinning medication; or
  • Patients with unstable metabolic disease/chronic diseases/ diseases with any comorbidities and/or any serious medical condition or abnormality of clinical laboratory tests that precludes the patient's safe participation in and completion of the study or puts them in a greater risk of developing severe symptoms (e.g. Individuals with an acute infectious disease, immune-compromised, self-reported confirmation of HIV, other lung diseases such as asthma, emphysema, neurological conditions); or
  • Patients who participated in other clinical research studies 30 days prior to screening; or
  • Patients who are participating in another clinical trial at the same time.
