Biocurious: Lumos shines a light on the post-pandemic rapid diagnosis sector

News.com.au29-04-2025

Lumos is commercialising its FDA-approved Febridx test to distinguish between viral and bacterial infections
The company's original Viradx flu assay was affected by a flood of cheap Chinese tests
Lumos is also developing a test to predict – and prevent – premature births
Lumos Diagnostics (ASX:LDX) CEO Doug Ward knows too well how quickly the competitive landscape for a medical device can change – and he has learnt some valuable lessons from the experience.
A year ago, the point-of-care diagnostics house was riding its fortunes on the back of Viradx, its US Food & Drug Administration (FDA) approved test for Covid and influenza A and B.
But a flood of Chinese and South Korean companies entered the US market, ahead of the last flu season.
While users liked Viradx, Lumos was forced to drop its price from US$12 to test to US$9 – but the rivals were selling theirs for US$3.
'They are now selling at a third of what our product sold at last year,' says the US-based Ward.
'It's not a robust market for us.'
Despite this aggressive pricing, Lumos reports new customer adoption owing to the severe US flu season.
Tapping his healthcare experience over three decades, Ward has focused Lumos's attention on its Febridx test, which can distinguish between bacterial and viral infections in ten minutes.
This is done by measuring two biomarkets simultaneously.
Approved by the FDA in October 2023, Febridx targets the over-use of antibiotics which contributes to the huge problem of antimicrobial resistance.
Let there be light
Lumos is a spin-off from the Melbourne-based Planet Innovation, which has a sound reputation for medical device design and development.
Lumos is chaired by Planet Innovation CEO Sam Lanyon.
Meaning 'light', Lumos debuted at the height of the pandemic in July 2021, having raised $63 million.
Lumos specialises in rapid point-of-care (POC) tests, to help healthcare professionals diagnose and manage medical conditions more accurately.
The kits are lateral flow, which means the sample flows horizontally over a strip containing the test reagents.
Lumos's offerings include customised assay development and manufacturing services for third-party POC tests, as well as proprietary digital reader platforms.
Andrew and Nicola Forrest's Tenmile Ventures last year became a 19.9% Lumos shareholder, having acquired its stake from Planet Innovation.
Let's be CLIA – it's important
The FDA's Febridx approval came after the agency initially rejected Lumos's submission, in 2022.
The agency opined that while the assay proved its chops at the bacterial-versus-viral bit, the agency was worried about false negative Covid results.
'The knock-back was a surprise because we met all the performance endpoints,' says Ward.
There's a complexity, in that the company had requested a so-called CLIA (Clinical Laboratory Improvements Amendment ) waiver.
The provision is for simple tests that have an insignificant risk of an erroneous result and can be used by less trained staff such as nurses and receptionists.
'It still needs to be in a healthcare setting, but that's it,' says Ward.
Other examples of CLIA assays are blood glucose, urine pregnancy and bowel cancer poo tests.
Currently, the FDA approval relates to 'moderate to complex' uses by a trained clinician.
Ward says the current market accounts for only 5% of the US$1 billion a year addressable market.
'That's why a why a CLIA waiver is so important to us,' says Ward.
'It will transform the company, big time.'
US government backed? You BARDA believe it
In its quest for CLIA status, Lumos in December launched a supportive study, with 350 patients tested to date.
The US disaster preparation agency, BARDA, is ponying up US$3 million to run the trial (contingent on various milestones).
The agency is also contributing up to US$5.3 million for a paediatric study.
While the trial is progressing well, there has not been enough bacteria-positive patients to power the study properly.
One reason is the bad but late US flu season meant here was over-representation of viral patients.
In its March quarterly report yesterday, the company reported that of the 351 patients tested to date, 37 had a bacterial infection, whereas a minimum 120 'bacterials' are needed to prove statistical significance.
Fortunately, the FDA has allowed an 'enrichment' process, by which Febridx can confirm patients already known to have the streptococcal A bacterial infection.
'Hopefully that will move us along a lot quicker,' says Ward.
The company targets study completion – and an FDA filing – in the December half.
Febridx addresses the issue of rampant over-use of antibiotics.
According to the US Centers for Disease Control and Prevention, more than 200 million antibiotic prescriptions are written each year.
About half are for acute respiratory tract infections and about 40% are unnecessary.
Women's health
Lumos's s next foray is in women's health, in collaboration with the Massachusetts-based women's' health specialist, Hologic.
The parties are developing a next-generation test for foetal fibronectin (FFN), a biomarker that points to a higher risk of pre-term births.
Under a US$10 million agreement, Lumos has licensed its proprietary reader and POC tech to Halogic.
Lumos also has dibs on up to US$5.5 million of milestone-based development payments from Halogic over two years.
The assay would replace the Halogic's current ageing FFN test, which is the only one on the market.
Lumos says the FFN work is 'progressing well', albeit about four months later than planned.
Old friends
In early 2023 the then cash-strapped Lumos vended some of the manufacturing equipment at its Carlsbad, California facility to Hologic, under a sale and leaseback arrangement.
This resulted in a $5.9 million in non-dilutive funding.
Hologic and Lumos know each other well, because Ward was business development manager for Hologic and Hologic was one of Lumos's biggest customers.
'There is a roadmap to develop other products with them as well,' says Ward.
'There's no point having a reader in a clinic only able to do one test, it takes up too much space.'
Outside of the Hologic tie-up, Lumos is mulling its own suite of women's health tests, for conditions including urinary tract and yeast infections and vaginitis.
'Most of these tests are done and sent to the lab and it takes days for a turnaround,' says Ward.
The company plans five to six tests, with the first two to be revealed in the December half.
Getting paid
As we've opined previously, regulatory approval amounts to a hill of beans without robust reimbursement in place.
In April Lumos secured Febridx reimbursement coverage for four Medicare Administration Contractors (MACs), at US$41.38 per test.
This takes coverage to four of the seven MACs, or 55% of total Medicare coverage.
Management is confident of snaring the remaining three.
'Medicare adoption generally serves as a precedent for reimbursement decisions by private insurance payors,' notes Lumos.
Febridx will drive growth
Lumos posted March quarter revenue of $3.5 million, 21% better than the December quarter tally.
Cash outflows were US$1.3 million, compared with a US$3.7 million deficit previously.
Of the revenue, 80% was derived from contract services for drug, diagnostic, food and environmental testing companies.
A company review in mid 2022 enunciated the services side as a key priority.
Having said that, Febridx offers the strongest growth prospects in a world in which clinicians and patients want an answer now, rather than when the lab decides to return a result.
Research platform MST Access says: 'the global healthcare system increasingly is prioritising rapid diagnostic solutions, particularly in infectious disease management and antibiotic stewardship.
'Lumos's proprietary technology addresses this need with point-of-care solutions that reduce the time to diagnosis and treatment.'

The US and China thrashed out their trade fight for 20 hours. Here's what they agreed to

Singapore: US officials said Chinese restrictions on the export of critical rare earth minerals and magnets had been resolved under a preliminary deal to resurrect a fragile trade truce struck in Geneva last month. Emerging from two days of intense discussions in London, US and Chinese negotiators said they had reached a new framework committing to the original trade deal struck on May 12, which almost unravelled in a dispute over China's export curbs on rare earths and US controls on technology sales. The new agreement still needs to be signed off by both US President Donald Trump and Chinese President Xi Jinping. Both sides offered few concrete details about what had been brokered over almost 20 hours of discussions. US Commerce Secretary Howard Lutnick said the framework would put 'meat on the bones' of the original deal, and that the dispute over rare earths would be resolved as a 'fundamental' part of the new agreement. Loading 'We have reached a framework to implement the Geneva consensus and the call between the two presidents,' Lutnick said after the talks wrapped up on Tuesday evening in London. 'The idea is we're going to go back and speak to President Trump and make sure he approves it.' China's Vice Commerce Minister Li Chenggang also said a trade framework had been reached that would be taken back to US and Chinese leaders for approval.

Peter Jackson stranded in Darwin Hospital after fall on Crown Princess from Sydney to Fremantle

Don't miss out on the headlines from News. Followed categories will be added to My News. What started out as a fun-filled holiday at sea turned into a dangerous nightmare for a man now stranded in a Darwin Hospital unable to get home to Western Australia. Peter Jackson and his wife Amanda set sail from Sydney to Fremantle on the Crown Princess and were having the time of their lives celebrating their 40th wedding anniversary until 63-year-old Mr Jackson fell backwards while re-embarking the vessel after ANZAC celebrations in Darwin. He suffered a bleed on the brain and was rushed to the ship hospital – but when the ship had to set sail, Mr Jackson was taken to Royal Darwin Hospital where he has since undergone two surgeries for brain bleeds. Peter Jackson and his wife Amanda set sail from Sydney to Fremantle on what was meant to be a dream holiday. Picture: Supplied 'He was unconscious for two days and we were told he was in trouble, and to prepare ourselves,' Mr Jackson's daughter Chloe Moloney told 'We were told Dad was too unwell to be transported and he needed to be stable for an airlift. Once he was stable, an airlift was to be done. Dad came around and improved and was moved to a ward.' But for reasons unknown to the anxious family, the medical transport back to WA was cancelled. Peter Jackson's horror holiday Start What started out as a fun-filled holiday at sea turned into a dangerous nightmare for Peter Jackson, who is now stranded in a Darwin Hospital - unable to get home to Western Australia. 'We couldn't understand why. Dad needs to be admitted to a neuro-rehab facility once a bed becomes available back home,' Ms Moloney said. 'Dad's speech has been impacted quite severely, he is quite hard to understand now. He also has issues with his right arm, and his high-level balance. Flying home commercially is not an option for us, with his condition.' Ms Moloney is desperate for answers and a solution. Mr Jackson has since undergone two surgeries for bleeds on the brain. Picture: Supplied Mr Jackson's wife has been keeping a beside vigil. Picture: Supplied 'On Wednesday last week we were told that neither the WA or NT governments wanted to pay for dad to get home, even though he needed to be admitted to a neuro-rehab facility,' she said. 'They said we needed to pay to get him on a commercial flight. From the research I have done I'm sure this falls under the national health form agreement, where the national government pays or they split the cost. 'The Royal Flying Doctor Service quoted $80,000 to fly Dad home. Mum and Dad have premium Ambulance cover which covers Air Ambulance but the health fund advised mum that St Johns Ambulance in Darwin do the patient transfers,' Ms Moloney said. Chloe Moloney with her parents Peter and Amanda Jackson on her wedding day. Picture: Supplied 'When called, St Johns gave mum a flat no, with no reason why. 'Mum had another quote that will provide a nurse on a commercial flight to sit in business class with dad and that costs $15,000. 'Where is she supposed to get all this money from when she has already spent thousands on accommodation so far to stay with dad? 'It's been a nightmare. We just want to get him home safely and get the ongoing care he needs,' Ms Moloney said. 'My dad is the most beautiful man. When he was of sound mind he would go out of his way to help anyone. Well now he needs help and we just can't get it.' Both the NT and WA Governments have been contacted for comment. A spokesperson for the Department of Health, Disability and Ageing said The National Health Reform Agreement recognises state and territory governments are the system managers of their public health and hospital systems. In their system manager roles, the Northern Territory (NT) and Western Australia (WA) Governments have policy and funding responsibility for their own ambulance and patient transport services, including associated fees and charges. The Australian Government does not have a role in administering patient transport. A spokeswoman for St John NT said 'this type of patient transport would need to be arranged by NT Health. If requested by NT Health, St John NT may facilitate the transport but we cannot initiate it.' Originally published as Cruise passenger stuck in hospital after nightmare trip
