Biome Australia has secured ethics approval from La Trobe University’s Human Research Ethics Committee for the Biome Australia BMB18 Clinical Trial, clearing the final regulatory prerequisite for the study to commence in February 2026. The randomised, double-blind, placebo-controlled trial will recruit 240 participants to investigate the efficacy of the company’s proprietary probiotic strain, Lactobacillus plantarum BMB18, in adults experiencing digestive symptoms, sleep disturbances, and mood issues.
Biome Australia clears final hurdle to commence BMB18 clinical trial
The ethics approval marks a significant regulatory milestone for (ASX: BIO), enabling the company to proceed with participant recruitment this month. The trial will examine BMB18’s impact on digestive function, mood, sleep quality, and overall wellbeing across two active dosage levels plus placebo.
The study represents a methodical step toward clinical validation of a wholly-owned intellectual property asset. BMB18 is registered with the German culture bank DSMZ under designation DSM 35214, providing the company with protectable intellectual property and potential future licensing opportunities.
Key trial specifications include:
- 240 participants recruited across three arms
- Two active dosage levels plus placebo control
- 12-month study duration from commencement
- Approximately $140,000 trial cost, managed within existing R&D budget
The trial’s dual-dosage design enables the company to identify multiple use cases for new product development, potentially supporting applications across both the Activated Probiotics and Activated Therapeutics ranges. This approach maximises the commercial utility of the clinical investment while maintaining rigorous scientific methodology.
For investors, the trial’s commencement on schedule demonstrates execution capability and de-risks timeline concerns. The company’s ability to deliver against stated milestones strengthens confidence in management’s strategic planning and operational capacity.
Understanding probiotic clinical trials and why they matter for investors
Clinical validation through randomised, double-blind, placebo-controlled trials represents the “gold standard” in medical research. In plain terms, this methodology means participants are randomly assigned to treatment groups (randomised), neither participants nor researchers know who receives active treatment versus placebo during the study (double-blind), and results are compared against an inactive control (placebo-controlled).
This rigorous approach eliminates bias and provides credible evidence of efficacy, which matters critically for both regulatory approval pathways and commercial credibility. For probiotic products targeting therapeutic applications, clinical validation differentiates proprietary formulations from generic strains lacking evidence-based support.
The trial process unfolds across three key phases:
- Ethics approval and regulatory clearance (now complete), ensuring the study meets safety and ethical standards
- Participant recruitment and intervention delivery (commencing February 2026), where subjects receive their assigned treatment over the study period
- Data collection, analysis, and outcome reporting (expected early 2027), determining whether BMB18 demonstrates statistically significant benefits
The gut-brain axis research field has gained substantial attention as evidence emerges connecting digestive health to systemic outcomes including mental wellbeing and sleep quality. Clinical validation of BMB18’s effects positions Biome Australia within this expanding research landscape, potentially unlocking product development opportunities aligned with growing consumer and clinical interest.
What BMB18 targets and the commercial opportunity
The trial will investigate BMB18’s efficacy in addressing specific health concerns: digestive symptoms such as bloating and discomfort, occasional sleep disturbances, and mood issues. These applications build upon successful in vitro research announced on 30 January 2025, which demonstrated BMB18’s ability to modulate immune responses and inflammation, reduce oxidative stress, and maintain intestinal barrier integrity.
Gut disorders and targeted gut health represent Biome Australia’s largest volume category. Clinical validation is expected to support growth across existing products whilst enabling new product innovation within the company’s established distribution channels.
The strain’s registration with DSMZ under designation DSM 35214 provides international recognition and intellectual property protection. This registration, combined with clinical data demonstrating efficacy, creates a defensible market position that generic competitors cannot easily replicate.

| Design | Randomised, double-blind, placebo-controlled |
| Participants | 240 |
| Arms | Two active dosages + placebo |

The IP advantage underpinning Biome’s competitive position
BMB18’s wholly-owned status distinguishes it from licensed strains that require ongoing royalty payments or carry usage restrictions. The company’s outright ownership enables flexible product development, licensing optionality, and protection from competitive encroachment on proprietary formulations.
Strain registration with DSMZ, an internationally recognised microbial culture collection, provides formal documentation of BMB18’s unique characteristics and establishes priority claims for commercial applications. This registration creates a barrier to entry for competitors and supports potential patent applications related to specific therapeutic uses.
Proprietary strains supported by clinical validation represent rare assets within the probiotics sector. Most commercial products rely on generic strains available to any manufacturer, competing primarily on price and marketing rather than differentiated efficacy claims. Clinical data demonstrating specific health benefits enables premium positioning and supports therapeutic claims that generic products cannot make.
“The value of owning a clinically validated, proprietary probiotic strain cannot be overstated. It provides Biome with product development opportunities, protection from competition, and potential licensing pathways that contribute to the long-term value of the Company,” said Blair Vega Norfolk, Managing Director.
Strategic fit within Vision 27
The BMB18 clinical trial aligns with Biome Australia’s Vision 27 strategic plan, specifically the supply chain development pillar focused on identification, characterisation, and commercialisation of proprietary probiotic strains. This framework guides the company’s R&D investments toward assets that strengthen competitive positioning whilst generating multiple commercialisation pathways.
The trial continues Biome’s research partnership with La Trobe University, following the successful Biome Lift™ Probiotic clinical trial collaboration. University partnerships provide access to research infrastructure, scientific expertise, and regulatory experience whilst managing costs within commercially viable parameters. The $140,000 trial budget demonstrates efficient capital deployment for a study of this scale and duration.
Management’s ability to deliver against communicated strategic priorities provides investors with confidence in execution capability. The progression from strain identification through in vitro validation to human clinical trials represents methodical advancement through development milestones rather than opportunistic pivoting.
What comes next for BMB18
Participant recruitment commences in February 2026, with the 12-month study expected to deliver results in early 2027. This timeline provides investors with a clear catalyst calendar for monitoring progress and evaluating outcomes.
Successful trial results will inform new product development across multiple potential applications, reducing dependency on single-use scenarios. The dual-dosage design enables the company to identify optimal formulations for different health indications, potentially supporting distinct product lines targeting specific consumer segments.
Key upcoming milestones include:
- February 2026: Participant recruitment begins
- Throughout 2026: Intervention delivery and data collection
- Early 2027: Trial completion and results announcement
- Post-results: Product development pipeline decisions based on outcomes
Clinical validation creates multiple value-generation pathways beyond direct product sales. Licensing opportunities enable the company to monetise BMB18 through partnerships with larger distribution networks or therapeutic product manufacturers. Regulatory submissions for therapeutic claims strengthen market positioning and support premium pricing strategies.
The trial’s design, examining multiple dosage levels and health outcomes, positions the company to extract maximum commercial value from the clinical investment regardless of which specific applications demonstrate strongest efficacy. This approach de-risks the binary outcome scenario where a single targeted indication either succeeds or fails.
