Gentle reminder from January24 Feb 2021 16:30
The Paraytec and University of Sheffield team will use these samples to set the test operational parameters so that it attains or exceeds the recommended guidelines for upper limits on false positive and negative tests set by the Medical Health Regulatory Authority. Results from this phase of clinical testing are now expected by the end of February.
To minimise the effects of this delay, Paraytec has brought forward scheduled work, using isolated lab-grown virus to optimise the operational sensitivity (sometimes called 'lower limit of detection') of our instrument for the detection of pre-symptomatic and early-stage symptomatic levels of virus. Paraytec's target is to detect less than 1000 virions per millilitre of sample, which would represent a market leading performance, if achieved. By re-arranging the workflows Paraytec does not believe that there will be any overall delay to the development programme.
It is already clear that current vaccines are not 100% effective and the infection risk is being compounded by the emergence of new strains of the COVID-19 virus. Braveheart has been advised that the Paraytec and University of Sheffield team believes there is, and will continue to be, a significant and ongoing demand for rapid tests for the early detection of the virus, to protect communities and the world's economy.
Braveheart and Paraytec remain committed to developing a test which achieves the performance parameters specified by the Medical Health Regulatory Authority and delivers a test result in five minutes. Detection tests show that Paraytec's aptamer based viral capture system completely traps target material in 300 seconds or less, confirming that its test platform is on target to deliver a test result within a five-minute timeframe, subject to successful completion of the clinical sampling tests.
Prof Carl Smythe, who leads the University of Sheffield team, commented, "We are very pleased with the rapid performance of our sample capture device. Together with the analytical sensitivity and speed of the optical system, we are on track to deliver a robust test that will support the level of infection control required globally."
