Nyrada’s Clinical Leap: Safety of NYR-BI03 to Be Tested in Humans

Nyrada Advances to Clinical Stage

Biotech company Nyrada Inc (ASX:NYR) has taken a pivotal step forward by receiving Human Research Ethics Committee (HREC) approval to commence its first-in-human Phase Ia clinical trial for its lead drug candidate, NYR-BI03. This milestone marks Nyrada's transition from preclinical research into clinical development, a critical phase for validating the safety profile of its innovative small-molecule therapy.

The Phase Ia trial is designed as a double-blind, randomized, placebo-controlled, dose-escalation study involving five cohorts of eight healthy volunteers each. Participants will receive intravenous doses of NYR-BI03 or placebo over three hours, with close monitoring for safety, tolerability, and pharmacokinetics. Recruitment is set to begin imminently, with the first dosing anticipated by the end of March 2025.

Promising Preclinical Data Underpinning Trial

NYR-BI03 targets Transient Receptor Potential Canonical (TRPC) ion channels and has demonstrated compelling neuroprotective and cardioprotective effects in preclinical studies. Notably, a 2024 stroke model showed a 42% rescue of brain tissue in the penumbra region, while a coronary heart disease model revealed an 86% cardioprotective effect following ischemic-reperfusion injury. These results position NYR-BI03 as a first-in-class candidate with potential applications across multiple indications.

CEO James Bonnar expressed optimism about the trial's commencement, highlighting the significance of moving into clinical testing. "The successful completion of this Phase Ia study opens the door to further clinical development across multiple indications," he said, underscoring the dedication of the Nyrada team in reaching this stage.

Trial Execution and Next Steps

Scientia Clinical Research will conduct the trial, supported by Southern Star Research as the Contract Research Organisation. Volunteers will undergo rigorous screening and safety assessments, including neurological and cardiac monitoring, before and after dosing. The study design allows for parallel recruitment and safety reviews to expedite progress, with a Safety Review Committee overseeing dose escalation decisions.

Final readouts from the Phase Ia trial are expected in the third quarter of 2025, with regular updates promised. Meanwhile, Nyrada is also awaiting results from a joint penetrating traumatic brain injury (TBI) study with the Walter Reed Army Institute of Research (WRAIR) and UNSW Sydney, which could further inform the clinical potential of NYR-BI03.

Implications for Investors and the Sector

This clinical milestone not only validates Nyrada’s drug development strategy but also enhances its profile within the competitive biotech landscape focused on neuro- and cardioprotective therapies. Successful Phase Ia outcomes would pave the way for expanded clinical programs and potential partnerships, while also providing a critical data point for investors assessing the company’s trajectory.
