PlaceboDrug
Diluent solution
| Study group | Role | What they receive |
|---|---|---|

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in viral load
Change in viral load from baseline to Day 8 based on quantitative reverse-transcription polymerase chain reaction of COVID-19 virus from oropharyngeal swab collection
Measured: Baseline through Day 8
Incidence of adverse events (AEs) (safety)
Safety as assessed by incidence of AEs by type, frequency, severity, and causality using the FDA Guidance for Industry: Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials
Measured: Baseline through study completion at up to 30 days
Secondary outcomes (4)
Change in viral load
Change in viral load from baseline to Day 4, Day 11 and Day 15 based on quantitative reverse-transcription polymerase chain reaction of COVID-19 virus from oropharyngeal swab collection
Measured: Baseline through Day 11
Participant perceived disease progression
Participants rate their progression of disease on Day 8 and Day 15 when asked "Have your COVID symptoms gotten worse since treatment?" Yes or No response
Measured: Baseline through Day 15
Rate of COVID-19-related medical visits
Determine the proportion of participants having COVID-19-related medically attended visits, emergency department assessments, hospitalization or all-cause mortality
Measured: Baseline through Day 30
Patient rated response
Proportion of participants scoring ≥ +1 and those scoring ≤ -1 using a patient global impression of change (PGIC) 7-point categorical scale on Day 8 and Day 15 when responding to the question "In terms of your COVID-19 symptoms, how much benefit if any did you receive from the treatment?" The 7-point scale range is -3 to +3 where -3 is "very much worse" to +3 "very much improved" based on how the participant feels post-treatment
Measured: Baseline through D15

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing STI-9199 in people with COVID-19, run by Sorrento Therapeutics, Inc. at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 13 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in viral load (time frame: Baseline through Day 8). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2023; AzTrials last refreshed its copy on 7 Nov 2026.
