Pathkey.AI Validates TrialKey With Strong Alignment To Clinical Outcomes

Pathkey.AI (ASX: PKY) has unveiled its first validation study of the TrialKey platform, an AI tool to predict clinical trial success.

The company reported that TrialKey correctly aligned with 73% of trial outcomes across 11 clinical programs that reported results between March and July 2025.

Management said the findings mark a critical step in proving the platform’s real-world utility across drug development, insurance and biotech investment markets.

Validation Study Demonstrates Predictive Strength

The study reviewed 11 programs that TrialKey had flagged as having above-average probabilities of meeting their primary endpoints compared to peers.

Eight of these trials achieved at least one endpoint, two failed, and one was terminated, indicating a strong correlation between prediction and outcome.

A hypothetical investment approach, where shares were purchased on the day of a TrialKey signal and sold when results were released, would have returned an average of 76%.

The best case was Abivax’s ulcerative colitis Phase 3 trial, which generated a 785% share price rise after TrialKey had rated it in the 91st percentile.

Other programs highlighted included Mineralys Therapeutics in resistant hypertension, which delivered a 56% gain following positive Phase 3 data, and Trevi Therapeutics, which saw a 64% rise after its Phase 2a success.

Implications for Drug Development and Markets

The early validation suggests TrialKey could help address one of biotechnology’s most persistent challenges: the high rate of clinical trial failure.

By analysing more than 500,000 historical studies with over 1,500 variables each, the system provides probability scores that go beyond intuition or precedent.

This capability has potential applications for trial sponsors looking to improve design and execution, as well as for insurers seeking better models for risk assessment.

Investors may also use the insights to identify opportunities in companies with higher chances of trial success.

The company stressed that TrialKey’s outputs represent statistical signals rather than guarantees, and that it has only used market reactions as an external proxy for validation.

Commercial Pathways Through Partnerships

Pathkey has entered into a non-exclusive partnership with L39 Capital, which is applying TrialKey insights to its AI Biotech Fund.

The agreement demonstrates one commercial application while allowing the company to retain flexibility for broader deployment.

“These results show how powerful TrialKey can be when applied to the world’s most challenging and consequential trials,” executive chair Saurabh Jain said.

“Clinical programs with strong TrialKey scores are consistently proving their merit in the market.”

The company believes each validation milestone expands the strength of its dataset and enhances confidence among potential partners, including pharmaceutical groups, contract research organisations and institutional investors.

Positioned for Future Growth

With ample cash to take it through mid-2026, Pathkey is in a position to continue building validation evidence as it monitors 20 additional NASDAQ- and ASX-listed programs with above-baseline probability scores.

Management said the broader industry is reaching a stage where scalable predictive tools are becoming essential to improve efficiency and reduce risk in clinical development.

Dr Jain noted that the next wave of results could help define both Pathkey’s growth trajectory and the wider adoption of AI in guiding drug discovery and trial investment decisions.

“Each validation strengthens confidence in TrialKey, expands our dataset, and enhances our ability to deliver insights to trial sponsors, CROs, insurers, and investors worldwide,”.
