COVID-19 Clinical Trial in St Louis, MO

About This COVID-19 Study in St Louis

This phase 1 randomized, open-label, dose-escalation clinical trial evaluates the safety and immunogenicity of OCU500, a ChAd36 Vector Encoding SARS-CoV-2 Spike Vaccine, in healthy adults aged 18-64 who previously completed a primary COVID-19 vaccination series and at least one booster. The study evaluates two dose levels (1×10\^10 viral particles (VP) and 5×10\^10 VP) and two routes of administration (intranasal and inhaled). The trial includes 80 participants across four study arms (20 per arm). The primary objective is to evaluate the safety and reactogenicity of a single dose of OCU500 administered in previously vaccinated healthy adults.

Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)

Participants of childbearing potential\

must agree to use or have practiced true abstinence\*\

or use at least one acceptable primary form of contraception.\*\*\

\*These criteria apply to females who are in a heterosexual relationship and are of childbearing potential. Not of childbearing potential include post-menopausal females (defined as having a history of amenorrhea for at least one year) or a documented status as being surgically sterile (hysterectomy, bilateral oophorectomy, or tubal ligation/salpingectomy). \*\*True abstinence is 100 percent of the time, no sexual intercourse (penis enters the vagina). Periodic abstinence \[e.g., calendar, ovulation, symptothermal, post-ovulation methods\] and withdrawal are not acceptable methods. \*\*\*Acceptable forms of primary contraception include a monogamous relationship with a vasectomized partner who has been vasectomized for 180 days or more before the participant's study product administration, a copper intrauterine device, a levonorgestrel-releasing intrauterine device, a progestin-only oral contraceptive pill, a depot medroxyprogesterone injection, or a progestin implant. Combined hormonal contraceptives containing estrogen, including combined oral contraceptive pills, transdermal patches, and vaginal rings, are not acceptable for this trial. Must have used at least one acceptable primary form of contraception for at least 30 days before study product administration and agree to continue at least one acceptable primary form of contraception through 60 days after study product administration.

Participants of childbearing potential must have a negative urine pregnancy test at screening and within 24 hours before study product administration.

In general, good health.\

\*As determined by medical history and physical examination, including vital signs, to evaluate acute or ongoing chronic medical diagnoses/conditions that have been present for at least 90 days, which would affect the assessment of participant safety. Chronic medical diagnoses/ conditions should be stable for the last 30 days (i.e., no hospitalization, ER, or urgent care for the condition). This includes no change in chronic prescription medication, dose, or frequency due to deterioration of the chronic medical diagnosis or condition within the 30 days preceding the study product administration. Any prescription change that is due to a change of health care provider, insurance company, etc., or done for financial reasons, and in the same class of medication, will not be considered a deviation of this inclusion criterion. Participants may be on chronic or as-needed (prn) medications if, in the opinion of the participating site PI or appropriate sub-investigator, they pose no additional risk to participant safety or assessment of reactogenicity and immunogenicity.

Receipt of a complete primary COVID-19 vaccine series and at least one booster\

with last vaccination at least 16 weeks before study product administration. \*Booster may be either homologous or heterologous to the primary vaccine series. It must be an FDA-authorized/licensed vaccine, though doses may have been received as part of a clinical trial.

Clinical screening laboratory evaluations are within normal reference ranges or grade 1 with no clinical significance (NCS) per investigator discretion.\
