Human-Relevant Testing.
Without Harming Animals.
Lebrun Labs has spent a decade building, validating, and patenting safety testing methods that achieve high accuracy and human relevancy and backed by $4.5M+ in NIH funding. We are now seeking the right partners to scale this technology globally.

Market Context
Why the Timing Is Right
Regulators Are Mandating Human-Relevant Science
The EU has banned cosmetics animal testing (EU Cosmetics Regulation 1223/2009). The U.S. EPA is phasing out mammalian toxicity studies (EPA, 2019). The FDA Modernization Act 2.0 (signed December 2022) explicitly requires consideration of human-relevant alternatives. Regulators worldwide are converging on the same conclusion: animal data is a poor proxy for human outcomes.
Human-Relevant Methods Outperform Animal Tests
OptiSafe™, IVD EIT™, and DermaSafe™ are validated, shelf-stable, nonanimal test kits and contract services, commercially ready today. Human-relevant methods are not just more ethical; they are more scientifically rigorous and reproducible than legacy animal tests.
De-Risked by $4.5M in NIH Funding
Over $4.5M in competitive NIH SBIR grants have funded the development and independent validation of Lebrun Labs human-relevant methods. Government-funded peer review is the strongest possible third-party endorsement of scientific merit and commercial readiness.
Intellectual Property Portfolio
Human-Relevant IP You Can Acquire or License
Five issued U.S. patents covering human-biology-based test methods, validated, commercially deployed, and accepted under OECD regulatory frameworks. Each method is designed around human biochemistry, not animal surrogates.
OptiSafe™
Human-Relevant Ocular Irritation Test, OECD 496
Models the biochemistry of the human eye, not rabbit ocular tissue. 92% accuracy for EPA classification, 88% for GHS, independently validated by NICEATM (National Toxicology Program Interagency Center for the Evaluation of Alternative Toxicological Methods). Outperforms the Draize rabbit eye test (~80% accuracy) by using human-relevant enzyme activity as the endpoint. (Lebrun, 2018; NICEATM validation report)
IVD EIT™
Human Tear Chemistry-Based Eye Irritation Test
The only nonanimal ocular test that incorporates patented human tear antioxidant chemistry (US12115147B2, US12521367B2), reducing false-positive rates from ~40% to ~20% (Lebrun et al., 2024; US12115147B2). Animal tests cannot replicate the protective antioxidant capacity of human tears; IVD EIT™ does.
DermaSafe SCT™
Human-Relevant In Chemico Skin Corrosion Test
Cell-free platform (US12559784B2) measuring enzyme activity reduction, a human-relevant biochemical endpoint. Extensible beyond skin to neurotoxicity, pulmonary, hepatic, and cardiac endpoints, all grounded in human biochemistry rather than animal surrogates.
Emergency Eyewash
Human Tear Chemistry-Inspired Ocular Protection (US12648892B2)
Formulated around the antioxidant chemistry of human tears. Clinically superior to standard saline eye wash protocols because it addresses the actual biochemical mechanism of chemical ocular injury in humans, not a generic dilution approach.
Watch Eye Wash Study VideoProduct Commercialization
Emergency Eyewash, Ascorbate Buffer
A portable, ascorbate-based emergency eyewash that outperforms water irrigation, backed by NEI CounterACT funding, a blinded human clinical trial, and a pending international patent portfolio.
Growth Opportunity
Patent Pipeline
Beyond the five issued patents, Lebrun Labs has additional patent applications pending, extending the human-relevant in chemico platform into new toxicity endpoints with no currently accepted nonanimal alternatives.
In Chemico Neurotoxicity Test
Extension of the DermaSafe SCT™ enzyme-activity platform to acute neurotoxicity endpoints. Applies the same human-relevant in chemico methodology to a toxicity category with no currently accepted nonanimal alternative, a significant regulatory and commercial gap.
In Chemico Pulmonary Toxicity Test
Applies the patented in chemico platform (US12559784B2) to pulmonary toxicity screening. Addresses growing demand from inhalation safety testing for industrial chemicals, consumer aerosols, and pharmaceutical inhalation products.
Expanded Ocular Irritation Classification
Next-generation refinement of the IVD EIT™ system incorporating additional human tear biochemistry markers to further reduce false-positive and false-negative rates across a broader range of chemical classes and formulation types.

How to Engage
Three Paths to Partnership
Equity Investment
Scale a Proven, Human-Relevant Testing Platform
Lebrun Labs has built the only commercially deployed, OECD-accepted nonanimal safety testing platform that models human biochemistry, not animal physiology. De-risked through $4.5M in NIH funding, independent NICEATM validation, and OECD regulatory acceptance, the platform is ready to scale. An equity investment would accelerate manufacturing capacity, grow the contract research team, and expand OptiSafe™, DermaSafe SCT™, and IVD EIT™ into new global markets.
Key Highlights
- Validated, human-relevant platforms that outperform legacy animal methods across ocular, dermal, and cytotoxicity endpoints
- Revenue-generating today: contract research and test kit sales
- Five issued patents covering human-biology-based methods and formulations
- Patent pipeline extending the platform to neurotoxicity, pulmonary, and hepatic endpoints
- Regulatory tailwinds: EU ban, EPA phase-out, FDA Modernization Act 2.0
- Scalable kit-based model with high gross margins
Strategic Acquisition / Buyout
Acquire the Leader in Human-Relevant Safety Testing
Lebrun Labs represents a rare opportunity to acquire a complete, commercially validated human-relevant safety testing platform, including five issued U.S. patents, OECD-accepted methods, established regulatory relationships, and a proven scientific team. The company is ideally positioned for acquisition by a CRO, specialty chemical company, cosmetics conglomerate, or safety testing firm seeking to lead the global transition from animal models to human-relevant science.
Key Highlights
- Turnkey acquisition: IP, validated human-relevant methods, team, and customer relationships
- Immediate revenue from contract research and kit sales
- Defensible IP moat: the only OECD-accepted human tear chemistry-based ocular test
- Patent pipeline adds additional unlicensed endpoints at no extra development cost
- Aligned with ESG mandates, animal welfare commitments, and regulatory direction
