About this study

Official title: A Phase I Double-blind, Randomized, Placebo-controlled Study to Evaluate Safety of Hypromellose-based Nasal Spray Solution Containing Human IgG1 Anti-SARS-CoV-2 Antibody Cocktail in Healthy Volunteers

Hypromellose-based nasal spray solution containing human IgG1 anti-SARS-CoV-2 antibody cocktail is a medical device innovated to provide the dual-action physical barrier on nasal mucosa that aids the natural defence in which the mucus layer is fortified by a steric barrier-forming agent HPMC and invading viral particles of all major SARS-CoV-2 VOCs, including Delta and Omicron, are locally trapped and blocked from entering the cells by the highly-specific human IgG1 anti-SARS-CoV-2 monoclonal antibody cocktail.

Read the detailed description

The transmission of SARS-CoV-2 through inhalation results in the nasal cavity and nasopharynx being the primary entry point of the virus and containing the highest viral load in the body during the virus incubation period. Recently, the administration of vaccines and agents via a nasal route has gained a lot of momentum because it takes advantage of the direct delivery of an agent to the site of primary infection. The local defence system, especially antibody-mediated immunity at the nasal epithelium, is crucial for COVID-19 prevention. However, people who responded to the vaccination against COVID-19 typically maintain sufficient local antibody levels in the nasal cavity for only a short period; hence a repeated boosting strategy is required to control the rate of SARS-CoV-2 breakthrough infection. In addition, the new VOCs such as Omicron are known to escape vaccine immunity; therefore, an innovative approach is needed in this unprecedented situation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adverse events

    Tolerability and safety of the study product as measured by treatment emergent adverse events (TEAEs)

    Measured: 1 Day

Secondary outcomes (1)
  1. Percentage of inhibition against SAR-CoV-2 in the nasal fluid

    SARS-CoV-2 inhibition property of the study product as measured by the percentage of inhibition against SAR-CoV-2 in the nasal fluid before and after the study product application via cPass™ SARS-CoV-2 Neutralization Antibody Detection Kit

    Measured: 14 Days

Questions about this trial

What is this clinical trial studying?

A study testing Human IgG1 anti-SARS-CoV-2 antibody cocktail in people with SARS CoV 2 Infection and SARS-CoV-2 Acute Respiratory Disease, run by Chulalongkorn University at 1 site in Thailand.

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 11 inclusion and 9 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: finished, as of the sponsor's last update on 7 Jul 2022. 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 Thailand. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Adverse events (time frame: 1 Day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05358873, which also lists 1 linked publication.

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 7 Jul 2022.
