Study type
Description of intervention(s) / exposure

This is a Phase I, single-site study to test the sensitivity, specificity and reproducibility of the Orbis QIC Test in vaccinated and un-vaccinated participants.

The Orbis QIC test is being developed as a rapid tool to assess an individual’s immune response to COVID-19 from a single finger prick of blood. The information gathered from this study will be used to further develop the device with the aim that in future it can be used as a screening tool for COVID-19 immunity.

The study will involve participants individually attending one clinic visit of approximately 30 minutes during which the following procedures will take place:
- Informed consent process
- Collection of demographic information including age, gender and ethnicity
- Collection of COVID-19 vaccination status and date of vaccination, if applicable
- Collection of the date and result of the participants most recent PCR test
- Two Finger prick blood samples will be collected

The study will be run at the airline's facility with the support of a private research study team. All members of the study team are appropriately qualified by education, training and experience suitable to their role in the study. The Orbis Arca device on which the QIC Test is run will be operated by trained Orbis personnel.

Can healthy volunteers participate?
Key exclusion criteria
1. Presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the participant or the quality of the data.
2. Currently being treated for or are known to be not completely free of symptoms associated with SARS-CoV-2 infection.
3. Known to be pregnant.
4. Partially vaccinated person (i.e. having received only one of the two vaccine doses)
5. For un-vaccinated participants, no previous confirmed or suspected SARS-CoV-2 infection, as determined by positive PCR, antigen, or antibody test, or by the determination of a government health agency.

Statistical methods / analysis
175 participants (100 vaccinated and 75 non-vaccinated) will be recruited. The sample size for vaccinated participants has been estimated to provide 80% power to satisfy the following performance specifications:
- Sensitivity >=87%, lower 95% confidence limit (2-sided) >74.4%
The sample size for unvaccinated participants is the recommended minimum number according to FDA guidelines, where specific power calculations are not required.
As a secondary aim for unvaccinated participants is the reproducibility of the assay, the number of vaccinated participants is higher than the minimum defined in the FDA guidance document (Policy for Coronavirus Disease-2019 Tests During the Public Health Emergency (Revised),” ) to facilitate the investigation of reproducibility.
For reproducibility, duplicate samples from all vaccinated participants and 8 (approximately 10%) of unvaccinated participants will be used.

Brief summary
The Orbis QIC test is being developed as a rapid tool to assess an individual’s immune response to COVID-19 from a single finger prick of blood. In future, this information may allow people to move around more freely if their risk of COVID-19 infection is known to be low, such as quarantine free travel for those with sufficient immunity.

The aim of this study is to test the Orbis QIC test device’s ability to:
- Detect IgG antibodies in individuals who have received the COVID-19 vaccine
- Correctly identify individuals who have not received the COVID-19 vaccine
- Repeatedly produce the same results
