NCT04834089

Brief Summary

Phase I/II Randomized Clinical Trial to evaluate the safety, pharmacokinetic and efficacy of Anti-SARS-CoV-2 hyperimmune serum. The study will include patients at early stage of COVID-19 with increased risk for severe disease due to underlying medical conditions to determine the utility of an equine heterologous serum anti-SARS-CoV-2 to avoid progression to a severe COVID-19

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults 18 years of age or older;
  • Diagnosis of SARS-CoV-2 infection confirmed by RT-PCR or antigen test no more than 5 days ago;
  • Onset of clinical signs and symptoms of COVID-19 no more than 5 days manifested as:
  • Presenting sudden onset of anosmia and/or ageusia without any other reasonable explanation and/or;
  • Thoracic image by radiography, tomography or ultrasonography compatible with acute clinical symptoms findings of COVID-19 and/or;
  • Acute onset of cough accompanied by fever and/or
  • Acute onset of three or more of the following symptoms: fever, cough, fatigue or general weakness, headache, myalgia, sore throat, runny nose, dyspnea, anorexia or nausea or vomit, diarrhea and mental status change.
  • Oxygen saturation by pulse oximetry ≥92%
  • Agree to periodic contacts by phone, electronic means and home visits;
  • Demonstrate intention to participate in the study, documented by Informed Consent Form signature on the part of the participant.
  • For the very high risk group:
  • Being on continuous drug immunosuppressant more than two weeks due to a basic medical condition (e.g. transplant or cancer);
  • For the high risk group:
  • To present at least two risk factors for developing serious COVID-19 (Over 60 years of age; diabetes mellitus; chronic obstructive pulmonary disease; kidney disease; cardiovascular diseases and body mass index ≥ 35).

You may not qualify if:

  • Behavioral, cognitive or psychiatric disease that, in principal investigator opinion or his/her medical representative, affect the participant capacity in understanding and collaborating with study protocol requirements;
  • Severe allergic reaction history or anaphylaxis to heterologous serum or product components of the study;
  • The participant is a team member who is conducting the study or is in a dependent relationship with one of the study team members. Dependency relationships include close relatives (in other words, sons, partner/spouse, brothers, parents), as well as Researcher staff or staff from the location conducting the study;
  • Any other condition that, in the principal investigator opinion or his/her medical representative, could threaten the safety or rights of a potential participant or which prevents him from fulfilling with this protocol.
  • For female:
  • Pregnancy (confirmed by positive β-hCG test), breastfeeding and/or expressing an intention to have sexual practices with reproductive potential without using a contraceptive method within four weeks of the product administration;

PARTICIPANT, INVESTIGATOR
Masking Details
Stage C of this study was designed as double-blind to avoid the bias introduction in the efficacy and adverse events evaluation. The clinical care team, the responsible professional for administering the serum and the participant will not know which product under investigation will be administered. Only the pharmacists or nurses responsible for the randomization of the study, separation and blinding of the product under investigation will have access to unblinded information. The allocation of the product under investigation will only be revealed after the completion of the participants' following up and database closing to guarantee a long-term safety evaluation of the product. The sponsor's operational team will also remain blind. If necessary, independent scientists not involved with the clinical or laboratory evaluation of the participants, who analyze the unblinded data of laboratory results.

Model Details: Phase I/II Clinical Trial, randomized, multicentric, on three stages (A, B and C) to evaluate the safety, pharmacokinetic and efficacy of Anti-SARS-CoV-2 serum and dose escalation. The study will be in three stages: Stage A: 30 kidney transplanted participants (very high risk), where 15 will received 1 vial (5 mL) and 15 will received 2 vials (10 mL) of serum; Stage B: 30 immunocompetent participants with at least 2 risk factors for severe disease (high risk) who will receive the dose selected by stage A; Stage C: 558 participants, of very high risk and high risk, compared with placebo in allocation 2:1.
