Brief summary

The main objectives of ECCO-2 are: 1) Efficacy: to study whether EQUINACEA ARKOPHARMA, hard caplets containing cryogenized root of the plant Echinacea purpurea, show an improvement of the clinical manifestations and disease course in ambulatory patients with covid-19 with a respiratory presentation and not requiring hospitalization (i.e., mild covid-19). The drug being evaluated will be added as a supplement of the standard treatment, with its current recommended dose for treatment of the common cold. 2) Safety: to determine that the incidence of adverse events is not higher than that seen with the standard treatment applied in each case.

Detailed description

Different presentations of the plant Echinacea purpurea are widely prescribed and used for the treatment of upper respiratory tract viral infections. The plant is known to contain an array of active principles including alkylamides, cichoric acid, glucoproteins resulting in stimulation of the innate immune system, in particular, an activation of macrophages and an increase of phagocytic activity (Nagoor Meeran et al. 2019. Heliyon, 7(2):e05990). It has also been recently shown to exert a direct antiviral effect against SARS-CoV-II in vitro (Signer et al. 2020. Virol J 17:136). EQUINACEA ARKOPHARMA is a pharmaceutical preparation of Echinacea purpurea prepared by controlled cryo-processing roots of the plant and packing the powder thus obtained in hard caplets. The product is a medicine approved by the European Medicines Agency for the treatment of common cold. In this study, 230 patients presenting with mild Covid-19 at the emergency room of 4 participating hospitals, with an eminently respiratory presentation, fever, and not requiring hospitalization, will be randomly assigned to two branches to receive EQUINACEA ARKOPHARMA or placebo, in a double-blind manner. Patients will be followed up for 4 weeks and the effect of treatment vs. placebo on clinical manifestations, duration of fever and of total disease and percentage of return to the emergency room and/or hospitalization will be assessed.

Inclusion criteria

* Age 18 to 99 años, with capacity to provide informed consent. * Covid-19 diagnose, confirmed by PCR or antigen test * Predominantly respiratory presentation. Additional minor digestive or/and neurological clinical manifestations will not lead to exclusion. * Axillary temperature equal to or higher than 37ºC, at some point during the evolution of clinical signs prior to recruitment, or at the moment of recruitment. * Being between days 1 and 9 of evolution of the disease, counting from the inception of symptoms. * Not having received any Covid-19 vaccine. * Capacity to complete the treatment, i.e., not having any swallowing difficulties, or any physical or psychiatric condition that would prevent the patient from taking caplets. * Patients that after being evaluated at the emergency room are deemed to be in a condition to follow treatment at home, with follow up by their family doctor, i.e., that will not be hospitalized.

Exclusion criteria

* Patients under 18. * Patients without a PCR or antigen test-based diagnose. * Asymptomatic patients. * Patients with an evolution higher than 9 days after the inception of symptoms * Patients with a predominantly digestive presentation. * Patients with a hypersensitivity to the active principle, any of the excipients of the drug or to the Asteraceae family of plants. * Patients with systemic progressive diseases such as tuberculosis, diseases of the immune system, collagenosis, multiple sclerosis múltiple, AIDS, VIH infections and other immune diseases * Patients previously treated at home with oxygen therapy. * Non-collaborating patients. * Patients without capacity to provide informed consent. * Pregnant or nursing patients. * Patients with an active immunosupressive treatment. * Women in a potentially fertile age will need to provide a negative pregnancy test before being including in the study. Subsequently, they will be instructed about the convenience of not becoming pregnant during the study. Only women using reliable birth control measures will be included. WOCBPs unable to guarantee reliable birth control during the study, or using unreliable methods such as coitus interruptus, nursing or just spermicides, will be excluded.
