Test, test, test!


It’s the World Health Organization’s battlecry in the global war against COVID-19 and other coronaviruses – including future outbreaks. And it is not getting any less resonant as new variants continue to cause havoc.


However, medical science is rising to the daunting challenge of regularly and accurately testing billions of people for highly virulent diseases. Among the most interesting stories to emerge in this Herculean endeavour is a life sciences company, XPhyto Therapeutics Corp. with multiple German biotech acquisitions under its umbrella.


With a focus on the burgeoning multi-billion-dollar disease detection market, XPhyto has just taken an aggressivestep towards becoming anindustry leader, beginning with the German market. This is Europe’s most populous nation, which benefits from one of the highest per capita rates of regular testing in the world. 


XPhyto has announced the pending acquisitionof Stuttgart-based 3a Diagnostics GmbH – a world-leader in developing disease-detecting medical innovations– in an all-cash transaction. For investors, this represents a major de-risking event as it provides XPhyto with complete control over the development, manufacture, distribution, and marketing of 3a’s disruptive pipeline of technologies. In other words, it makes for a fully integrated business model.


According to a company’s July 20th news release, there are other strategic and logistical benefits to this transaction, as described below:


“The planned acquisition of 3a is expected to result in: significant synergies in research and development and manufacturing; significantly improved margins for commercial products, such as the 25-minute COVID-ID Lab test; as well as expedited commercialization of products in 3a's near-market development pipeline.”


Until now, 3a has acted as an exclusive joint venture collaborator in the development of COVID-19 screening diagnostics and other disease-detecting technologies for the European market. It also holds the intellectual property (IP) rightsfor these innovations, which were originally licensed to XPhyto for commercial use.


Now that the pending acquisition of 3a has been announced, the process of bringing the company’s disease-detecting biosensor technologies to market will begin in earnest, according to XPhyto’s Germany-based COO, Wolfgang Probst.


3a is a commercialinnovator that is singularly focussed on the diagnostics and biosensor markets, having developed plenty of expertise in developing point-of-care screening systems over the past decade.


Probst says XPhyto is already successfully leveraging 3a’s proprietary skill set with the recent commercial launch of what may be one of the world’s fastest portable PCR (molecular) diagnostic testing system for COVID-19. These test kits are already in use in 10 testing facilities in Berlin, which have taken delivery of the first 1,000 units for evaluation and planning. Multiple purchase orders are expected to flow from this contract. More on this in a moment.


Why the Biosensor Business is Booming

3a has developed a pipeline of peptide-based biosensor screening tests for bacterial and viral infectious diseases – which is a burgeoning multi-billion-dollar market segment.


Last week, XPhyto announced that 3a has now identified the first saliva-activated biosensor molecule for the detection of a COVID-19 infection. This represents a technological breakthrough as a low-cost alternative to conventional antigen screening and expensive RNA testing. XPhyto says this enzyme-activated biosensor has the potential to be commercialized along an expedite timeline, taking months, rather than years.


These biosensorsare a combination (chemical conjugate) of a pathogen specific biosensor molecule and an extreme (but safe) bitter compound. When the biosensor is exposed to specific bacterial and viral enzymes, this triggers biosensor activation and release of the extreme bitter-tasting compound, alerting the user to presence of the specific pathogen.


This oral screening technology is designed to instantly detect a variety of bacterial and viral infectious diseases. 3a’s development pipeline includes biosensor products for influenza A, stomatitis, periimplantitis, periodontitis, and group A Streptococcus.


Even though biosensors may not seem like a familiar term to many readers, it will not remain that way, much as the term coronavirus has become commonplace.


To this point, the market valuation of biosensors is expected toreach $42 billion by 2027, according to the Delaware-based market intelligence firm Global Market Insights (GMI).This would effectively nearly double biosensor marketplace in size within a few short years. 


“Increasing numbers of product launches, coupled with rising adoption of novel biosensors will stimulate the global market expansion,” GMI states in a recent research report.


“Early and precise disease diagnosis is essential for the timely prognosis and the survival of the patient. In recent years, the demand for disposable, cost-efficient, and user-friendly devices with fast response time has extensively increased.”


XPhyto’s stated goal is to develop rapid, low-cost, easy-to-use pathogen screening tests for pandemic and other health applicationsthroughout Europe and the Middle East. To this point, XPhyto is integrating 3a’s biosensor technology into its own proprietary oral drug delivery platform, creating ultra-low-cost oral dissolvable screening tests.


Global Market says that biosensors are expected to take on an increasingly integral role in containing and curtailing outbreaks of disease.


“Biosensors have emerged in several fields such as diagnosis, patient health monitoring, detection of disease, and human health management, that will further aid in paving robust growth opportunities in the future,” the report also says.


“Their role in fighting coronaviruses cannot be overstated either,” according to Global Market.“COVID-19 has positively impacted the global biosensors market…These advanced biosensors are employed not only for real-time COVID-19 detection but also as a global screening tool to address control, surveillance, and preparedness in the event of future outbreaks.”


Covid-ID Lab: A PCR Test Disruptor

Earlier this year, XPhyto launched Covid-ID Labin Germany as a commercial in-vitro diagnostic (CE-IVD) test – one that is registered within the European Union. This portable point-of-care PCR testing system makes possiblefast, highlyaccurate testing in a diversity of real-world settings.


It effectively decentralizes the whole testing process, making it logistically possible to provide on-site testing and results at numerous locations simultaneously.


Taking only 25 minutes to generate a definitive diagnosis, this portable Covid-ID Lab has the capacity to simultaneously process up to 96 test samples within 25 minutes, depending on the equipment and staffing.


According to Probst, Covid-ID Lab’s differentiating appeal is its uniqueness.
“Covid-ID Lab is a specialized product that is designed to fill the market gap between disposable antigen tests and centralized automated PCR systems,” he said.


“Examples of target customers are airports, cruise lines, pharmacies, medical clinics, and any industrial or education site that requires rapid, definitive results.It is also ideal for pop-up testing centres. In fact, with our technology, we expect to be able to run small satellite labs. This opens up many potential testing labs throughout Germany.”


Probst explains why he believes Covid-ID Lab is a superior product to widely-used lateral flow assay antigen tests.


“Our tests find coronavirus-infected people before an antigen test can, which only kicks in when a higher viral load is reached. As a result, many people with the disease have a negative test, feel safe, go shopping and spread the virus in the process.


With XPhyto’s test, the genetic material of the viruses is amplified to such an extent that SARS-CoV-2 can be detected even if only small amounts are present. This is how PCR works and why it is the diagnostic standard.”


Probst expects that this test will have strong adoption in densely populated metropolitan areas and at transportation hubs such as train stations and airports where the need for rapid, accurate and cost-effective tests is high.


It is worth noting that someinfectious diseasesexperts predict that the EU and North America will never achieve full immunity and that COVID-19 may become a seasonal virus – like influenza – because the reinfection of coronaviruses is common.


According to Professor Ali Mokdad from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, “We’re not going to reach herd immunity. It’s going to be seasonal, and it’s going to be like the flu, and we’re going to need to be ready for it.”


It is therefore no surprise that the market for coronavirus testing is growing exponentially. By the estimation of Allied Market Research, it is likely to grow by almost 9% per annum until 2023, swelling to $39.1 billion.


The key takeaway here is that the widespread adoption of rapid, ultra-reliable PCR testing at a wide diversity of point-of-care settings, including pop-up facilities, could be critical to helping break the chain of transmission. It may also prove helpful in monitoring the effectiveness of the vaccines that are being widely administered in Europe and North America.


Taking Rapid Testing to the Next Level

In recent months, the go-to protocol for fast COVID-19 testing in real-world situations has been antigen testing – a fast and inexpensive test that relies on a nasal swab or sample of saliva.


The drawback to antigen tests is that they have been shown to generate substantialfalse positive readings, as well as a smaller percentage of false negatives. However, they had generally been considered as a first line of defence and better than nothing by some European health authorities.


In the UK, the government has run out of free lateral flow tests due to continued strong demand. Similarly, in Germany, lateral flow tests have become ubiquitous with millions of tests being conducted every day. However, the opportunity to make these tests more effective and more reliable is something that has Probst excited.


Indeed, as countries tentatively re-open their economies, there is growing consensus that rapid PCR screening in point-of-care settings will be integral to keeping economies open while still protecting the world’s population–particularly vulnerable citizens. 


By being able to test, trace and quarantine anyone who is sick, health authorities should also be able to break the chains of transmission and finally bring COVID-19 infection rates and their variants under control.


XPhyto expects to play an important role in taming the pandemic in Europe and elsewhere. At the same time, it also aims to facilitate the early detection of many other bacterial and infectious diseases with its enzyme-based biosensor technologies.


The pending acquisition of 3a Diagnostics promises to further heat-up XPhyto’s story, which is why this enterprising start-up is already being closely followed by Germany’s media.


On a technical note, the company’sshare price still benefits from a relatively tight share structure of approximately 73million shares outstanding, while its market capitalization is less than CDN $150 million.


The recent exercise of a large block of warrants has exerted downward pressure on the share price, while at the same time it has topped up the company’s treasury. But the exercise date for those warrants expired July 30th, which should help trigger a technical rebound in the company’s share price.


Plus, there is expected to be plenty of upbeat news to report in the coming months to potentially power its share price forward.


This is especially the case for XPhyto’s flagship COVID-ID Lab product – a fast, point-of-care PCR diagnostic system, which promised to become a highly disruptive technological and commercial success, not just in Germany, but throughout the rest of Europe, as well as the Middle East.


Additionally, it bears restating that XPhyto has just announced another highly differentiated technological breakthrough by way of the validation of an in-development enzyme-activated, oral biosensor for the detection of COVID-19. Notably, the company believes that this highly disruptive, low-cost, easy-to-use, orally dissolvable biosensor product has the potential to be commercialized in a matter of months. 


In other words, the company is now firing on all cylinders and its share price is primed to benefit sooner or later in 2021 from the XPhyto’s ascending fortunes in a booming diagnostics industry.
