Phase IIa Randomized Placebo Controlled Clinical Study of Codivir in Hospitalized Patients with Moderate COVID-19

Обзор

This is a double-blind, multicentre, multinational study to evaluate the safety and collect preliminary efficacy data of Codivir drug product in 130 hospitalized adults with moderate COVID-19 symptoms. COVID-19 symptoms (fever, cough, myalgia and changes in smell or taste) onset must be within 7 days prior enrolment. Treatment will begin in the hospital, participants will be discharged according to medical decision and continue the treatment until to Day 7 at home and followed up to day 28.

Подробное описание

eligible hospitalized participants will be recruited to the study and will receive standard of care treatments as well as Codivir or placebo, which will be administered at a dose of 20 mg SC, twice a day, for 7 days. If up to medical decision of the medical staff in the site, the patient should be released before Day 7, site study team will contact the medical monitor of the study to get the instructions. Participants will be followed up to the 28th day via phone contact. The phone visit will be performed to monitor the clinical symptoms, collect adverse events and concomitant medication and provide the patient with additional instructions, if relevant.

If they have progressed well, they will continue the treatment up to Day 7 at home, receiving a nurse's home visit twice a day to administer Codivir and collect vital signs. Participants will be followed up to Day 28 by telemedicine. A doctor will call them periodically to monitor the clinical evolution, collect adverse events, concomitant medication and instruct the participants. In case of unfavorable evolution, the participants will remain hospitalized receiving the appropriate care. The investigator will decide whether or not the investigational medication will continue, considering the participant's health and well-being.
