Achiko AG Reports Breakthrough Calibration Results for its AptameX™ Covid-19 Rapid Test Technology
Achiko AG has announced significant advancements in its AptameX™ Covid-19 saliva-based rapid test, achieving 100% sensitivity and specificity across various viral load ranges, with results confirmed from 58 human samples. The test outperformed conventional rapid tests, particularly in the critical CT value range of 25-33. Production scaling is underway, targeting one million kits per month, alongside the completion of the CE Mark for broader market access. These developments position AptameX as a cost-effective alternative to traditional testing methods, particularly beneficial for lower-income regions.
- Achiko's AptameX™ Covid-19 test achieved 100% sensitivity and specificity in recent trials.
- The test performs well even at higher CT values (25-33), exceeding many competing rapid tests.
- Production is scaling to one million kits per month, which indicates strong operational capacity.
- The completion of CE Mark registration is anticipated to unlock significant market opportunities in EMEA.
- None.
- AptameX™ Covid-19 rapid calibration successfully classified
100% of results indicatinga likely >97% Sensitivity and >97% Specificity result in the first-generation test kits. - Results were demonstrable both at CT values under 25, and between 25 to 33, indicating superior test performance to other rapid tests.
- Achiko is now moving to scale production and completing CE Mark to respond to global demand.
ZURICH, Switzerland, Jan. 14, 2022 (GLOBE NEWSWIRE) -- Ad hoc announcement pursuant to Art. 53 LR – Achiko AG (SIX: ACHI; OTCQB: ACHKF; ISIN CH0522213468) (“Achiko”, the “Company”) is pleased to report that new optimizations during recent calibration testing of its affordable, non-invasive Covid-19 saliva-based rapid test AptameX™ correctly differentiated
“The data we’re reporting today shows that our technology allows for more sensitive and affordable tests compared to antigen-based tests,” stated Achiko CEO Steven Goh. “These high-fidelity calibration testing results suggest not only that AptameX has potential as a very compelling alternative to rapid antigenic tests, but also may be used as an accurate alternative in many mass market applications to slow and expensive RT-PCR technology. This is particularly important in Lower to Middle Income Countries (LMIC) where vaccination rates are lower and the leading testing technologies are impractically expensive for the vast majority of people.”
New data (see table below) announced today for the first time show that, after the recent improvements, AptameX achieved
The experiment was conducted in Indonesia using samples that were confirmed positive or negative for SARS-CoV-2. AptameX delivered a sensitivity of
| CT Value (mean & range) | Number of Specimens | Classification for Sensitivity | ||
| High (CT =< 25) | 17.6 / 13.4 – 23.0 | 16 | 100 | % |
| Low (25 < CT =< 33) | 30.5 / 25.8 – 33.0 | 12 | 100 | % |
| Negative | - | 30 | - | |
| Average | 23.15 / 13.4 – 33 | 58 | 100 | % |
These results compare favorably to other testing technologies. Because of its accuracy, RT-PCR technology has become the gold standard for detecting Covid-19 infection. However, RT-PCR is often not the most practical for large-scale testing because it requires specialized equipment, is relatively slow and expensive. Using RT-PCR technology, scientists have established a benchmark for detecting Covid-19 infection: a healthy person is considered Covid-19 negative if their RT-PCR CT value is greater than 33. If, however, the CT value is below 33, the person is Covid-19 positive. Most rapid tests may tout a high sensitivity result where the CT values are under 25. However, according to Euro surveillance, more recent work on Omicron indicates the mean value for Covid-19 infection is around 28, hence the frequent reports of lower sensitivity in the majority of antigenic rapid test kits. Therefore, the AptameX result is important as it presents a viable alternative to other testing.
"The improved sensitivity and specificity results announced by Achiko following completion of calibration testing on its SARS-CoV2 rapid test kit is a significant milestone,” stated AptameX inventor Dr. Michael Edel. "AptameX has the capability to meet the increasing global need for frequent mass testing that is fast, low-cost and non-invasive.”
Furthermore, the AptameX test has completed and tested its first few hundred thousand kits in production and is now moving to produce one million kits a month. From there, the format is highly amenable to large-scale manufacturing and offers a considerable production cost advantage. Late last year the Company optimized the first-generation test kit using a simpler supply and manufacturing chain in Taiwan and Indonesia, that can easily be replicated to other geographies. In a matter of months and subject to financing, production capacity can rapidly be scaled to hundreds of millions of kits per month. The Company is looking to finance scale production primarily through trade finance.
Production of the second-generation rapid test kits is underway and will ramp up further this quarter. Shipments of AptameX kits within Indonesia have been completed to meet prior sales orders as the Company expects to be able to provide 3-4 tests per months for
“It’s evident that as we move to the endemic phase of Covid-19, regular vaccinations and mass testing will become a part of our daily lives,” added Goh. “We are enormously pleased with the great results we are able to share today. They confirm the competitive positioning of the platform and the role we can play in getting us all back to a ‘normal’ life.”
