ClinConnect Summary

RT-CoV-2 is a Phase I, open-label, dose escalation multicenter clinical trial to assess safety and immunogenicity of the candidate Coronavirus disease (COVID-19) vaccine GRAd-COV2 in Italian healthy volunteers aged 18-55 years and 65-85 years inclusive. GRAd-COV2 is based on a novel replication defective Gorilla Adenovirus and encodes for SARS-COV-2 full length prefusion stabilized Spike protein. GRAd-COV2 is developed and manufactured by ReiThera Srl.

This study will evaluate a singular intramuscular administration of GRAd-COV2 at 3 dose levels: 5e10, 1e11, 2e11viral particles (vp). There...

• • 12. Should not show laboratory values outside the normal range which may have clinical significance even in absence of specific signs or symptoms.
• Exclusion Criteria:
• A subject who meets any of the following criteria will be excluded from participation in this study:
• • 1. Positive serology for anti-HIV-Ab
• • 2. Positive HbBsAg
• • 3. Positive anti-HCV-Ab
• • 4. Positive for SARS-CoV-2 (either anti-S-Ab or anti-N-Ab)

• • 8. History of atopy (or any IgE associated condition) who had required treatment over the last 6 months;
• • 9. History of hypersensitivity or severe allergic reaction (e.g., anaphylaxis, generalized urticaria, angioedema, other significant reaction) to any previous licensed or unlicensed vaccines;
• • 10. Assumption of any immunomodulatory medication over the last 4 months (including, but not limited to, systemic corticosteroids, allergy injections, immunoglobulin, interferon, immunomodulators, cytotoxic drugs, or other similar or toxic drugs).

• • 18. Currently enrolled in or plans to participate in another clinical trial with an investigational agent that will be received during the study-reporting period.
• • 19. Administration of immunoglobulins and/or any blood or blood products within the 4 months before the first vaccine administration or at any time during the study.
• • 20. Has any significant disorder of coagulation.
• • 21. Has any chronic liver disease, including fatty liver.
• • 22. Has a history of alcohol abuse or other recreational drug use within 6 months before the first vaccine administration.

• • 25. Has been reported as a case (confirmed or probable) of COVID-19 from the regional health system
• • 26. Has any clinical conditions that, in the opinion of the site PI or appropriate sub-investigator, precludes study participation, this includes any acute, subacute, intermittent or chronic medical disease or condition that would place the subject at an unacceptable risk of injury, render the subject unable to meet the requirements of the protocol, or may interfere with the evaluation of responses or the subject's successful completion of this trial
