("NorthStrive Biosciences"), a subsidiary of PMGC Holdings Inc. (NASDAQ: ELAB) ("PMGC" or the "Company"), today announced positive results from Phase III of its AI-driven drug discovery program with strategic partner Yuva Biosciences, Inc. ("Yuva Biosciences"). Phase III of the parties’ drug discovery program (“Phase III”) was designed to biologically validate a focused set of small-molecule candidates selected by Yuva Biosciences' proprietary MitoNova™ AI platform. These candidates were tested in primary human skeletal muscle cells using an in vitro assay measuring ANT1 protein expression. ANT1 is a mitochondrial protein involved in cellular energy metabolism in skeletal muscle. The parties’ drug discovery program is focused on identifying candidates that may support the Company's broader development strategy around muscle preservation, including potential applications relevant to muscle health and metabolic stress. The study in Phase III evaluated a focused set of AI-selected small-molecule candidates. According to the results package prepared by Yuva Biosciences, four compounds (C1, C2, C3, and C4) increased ANT1 expression, with the strongest candidates demonstrating dose-dependent induction. Yuva Biosciences’ results report identified C1, C2 and C4 as the strongest and most dose-consistent ANT1 inducers, while C3 also advanced as a candidate based on statistically significant activity at the highest tested dose.

The prior update also stated that Phase III results were expected in Q2 2026. <a href="https://www.globenewswire.com/Tracker?data=13U5c9BRK6dFavgvrqrDHS0GzGp95yc1mAEyA7SvRPlhcP1fepjnd6x3ZhsCue8RJX6AbW5eGk6t9AX_iLxREEM20mChK_aMplFXMDOWK4U6cH-YglcEsjL_gf--v88UkhXQt3RqMoQANWCFTitto-NtjpPzOfJTTfdETUazbRONYiezb-mfzgNaY-LJ8_yfGsZLkmxg4cubirXLmwBFhTpAoLvqawjtHDpMl_h3sTcPl3COj6iruSC1jh1x_Raq" rel="nofollow" target="_blank" title="">View the prior PMGC press release.</a> Next Steps Based on the positive Phase III results, NorthStrive Biosciences and Yuva Biosciences are evaluating next steps, including confirmatory testing and further development of the four validated candidates. The proposed next stage is expected to evaluate whether the ANT1 induction observed in primary human skeletal muscle cells is maintained in a more mature muscle model that more closely reflects adult skeletal muscle biology.
