To counter the worldwide growth of antimicrobial resistance, a subject of worldwide concern but little actual progress, Arrepath Inc. has raised a $20 million seed financing to advance its machine learning-based platform for discovering new classes of anti-infectives.
Selux Diagnostics Inc. raised $50 million in a series C financing to support the commercial launch of its next-generation phenotyping (NGP) rapid antimicrobial susceptibility testing platform. RA Capital Management LLC led the round with participation from Sands Capital, Schooner Capital and Northpond Ventures, all returning investors.
Lyme disease is the most common vector-borne disease in the U.S. and is also common in certain areas of Europe. Yet, despite this, there are no FDA-approved vaccines available to treat it, meaning those diagnosed must receive a dose of antibiotics. But antibiotics are problematic because of the risk of treatment-resistant strains emerging. That leaves a pressing need for a vaccine or other way to prevent infections from the tick-borne bacterium Borrelia burgdorferi.
A team led by researchers from the ETH Zürich and the University of Basel has used a combination of mass spectrometry data and machine learning to predict antibiotic resistance of clinical bacterial samples. The results, which were published in the Jan. 10, 2022, issue of Nature Medicine, could speed the identification of optimal antibiotic regimens for patients.
It’s been seven years since economist Jim O’Neill began his review on antimicrobial resistance, commissioned by the U.K. government to find ways to encourage development of badly needed new antibiotics. Since then, the pandemic has produced radical changes in society and forced pharma to refocus its R&D priorities at short notice. But COVID-19 has also raised awareness about the devastating effect that rogue pathogens can pose to society, and there are now serious moves to prevent a global catastrophe caused by antibiotic resistant bacteria.
An international study led by scientists at the University of Exeter in the U.K. suggests how to combine antibiotic and bacteriophage therapy optimally, in order to reduce antibiotic use and potentially prevent multidrug resistance in bacteria.
Antibiotics continue to take a beating as top-line results from Summit Therapeutics Inc.’s phase III study of ridinilazole failed to meet the primary endpoint for sustained clinical response and treating C. difficile infection (CDI). Looking for an upside on its lead candidate’s results, the company noted participants treated with ridinilazole had substantially less recurrence of CDI, the most common cause of diarrhea in hospitalized patients, as compared to those who were administered vancomycin (nominal p-value = 0.0002).
Even as antimicrobial resistance is expected to continue to grow, the development of much-needed novel antibiotics and antifungals remains trapped in a catch-22 in which funding is available for early stage research but not necessarily for the translational work necessary to bring the drugs to market.
Developing the next generation of antibiotics is proving to be a major problem, with research reaching an almost standstill due to a lack of funding because of the poor return on R&D investment from the products.
LONDON – Persica Ltd. is poised to take a new pharmaceutical approach to curing chronic lower back pain, after delivering positive data in a phase Ib study of an injectable antibiotic. The development rests on research showing that, as with stomach ulcers, chronic lower back pain is caused by localized bacterial infection.
