Antibiotic resistance: a matter of time

/in , , , /by
“Is this just a projection…?”  The narrator of this video asks, as she examines the possibility of a world devoid of effective antibiotics, a most precious resource. Due to “use, misuse, overuse” of antibiotics, a dire future is forecast. It is thought provoking, unnerving – but also deeply motivating to be part of global action to address antimicrobial resistance (AMR). Here at Botanix, we are committed to developing novel solutions to address AMR through our BTX 1801 pipeline. In World Antimicrobial Awareness Week (#WAAW) it’s encouraging to see this vital conversation gaining momentum too.  Watch the video on Financial Times here. 

New antimicrobial data and conference presentation

/in , , , , /by

Botanix Pharmaceuticals (ASX:BOT) has today shared a market update and new data pertaining to the BTX 1801 antimicrobial program, which is currently being studied as part of a Phase 2a clinical trial in Perth.  

The new data demonstrates BTX 1801 eliminates methicillin-resistant Staphylococcus aureus (‘MRSA’ or ‘Golden Staph’) from human skin explants infected with MRSA. It also confirms synthetic CBD’s novel mechanism of action, where treatment with CBD rapidly disrupts the bacteria’s membrane resulting in cell death.

The latest news was captured as part of a presentation shared by Botanix President and Executive Chairman, Vince Ippolito, for the ASX Small and Mid-Cap Conference today – which features a close-up look at the mechanism of action.

The Botanix team is extremely encouraged by this new data and remains confident that BTX 1801 will be a valuable treatment option for the prevention of post-surgical infections, which are often serious and can be life-threatening. Addressing antimicrobial resistance (AMR) remains a foremost priority for the Company, alongside the  largest health agencies in the world.

NEW DATA | Time lapse videos – S.aureus treated with synthetic cannabidiol

Botanix Pharmaceuticals released promising new clinical data for its BTX 1801 antimicrobial platform and a supporting presentation today.

The results demonstrate how synthetic cannabidiol kills resistant bacteria quickly and effectively – specifically Staphylococcus aureus (‘S.aureus’  or‘MRSA’ or ‘Golden Staph’), which greatly increases the risks of serious and life-threatening infections following surgery when it is carried in the nasal passage.

The following time-lapse videos clearly show how synthetic cannabidiol kills bacteria by rapidly disrupting the bacterial cytoplasmic membranes in as little as 10 minutes. In both videos, the bacteria are initially surrounded by a green fluorescent dye and exclusion of the dye means the bacteria are alive and well, while uptake of the dye means that the bacteria’s cell membrane has been disrupted and they are dying.

Time lapse video – S.aureus treated with methanol

This time lapse video shows S.aureus treated with 2.5% methanol (negative control) and grown at room temperature on an agarose pad containing 0.25µM SYTOX-Green. Bacteria are happy and rapidly multiplying over the 120 minutes, with no uptake of the dye.

Time lapse video – S.aureus treated with synthetic cannabidiol

This time lapse video shows S.aureus treated with with synthetic cannabidiol and grown at room temperature on an agarose pad containing 0.25µM SYTOX-Green. In contrast to the first video, bacteria immediately start to die, as evidenced by the rapid uptake of dye and disintegration of bacteria.
