AI-Designed GLP-1 Peptides from ImmunoPrecise Antibodies Surpass Semaglutide in Receptor Activation Studies

Breakthrough in AI-powered drug discovery validates HYFT®-driven peptide design, with broad potential across multiple therapeutic areas

AUSTIN, Texas – ImmunoPrecise Antibodies Ltd. (NASDAQ: IPA), a leader in AI-powered drug discovery and biotherapeutics, today announced compelling in vitro results demonstrating that its artificial intelligence (AI)-designed GLP-1 receptor agonist (GLP-1RA) peptide sequences achieve comparable or superior receptor activation to Semaglutide, a benchmark GLP-1 therapy and one of the most commercially successful drugs in the world. The in vitro analysis was conducted by an independent third party, further strengthening the objectivity and reliability of the findings.

The results validate the power of IPA’s LENSai™ platform powered by its proprietary HYFT technology, which enables first-principles-based in silico peptide discovery and optimization. Five rationally engineered peptide sequences—AI-optimized for improved stability and peptidase resistance—were tested against benchmark GLP-1 analogs in receptor activation assays. Two lead candidates outperformed or matched Semaglutide under controlled assay conditions.

Crucially, the sequences were not discovered by chance. They were designed using HYFT-derived intrinsic biological patterns—mathematical representations of functional relationships in biology—making this approach highly reproducible and generalizable to other drug targets.

With GLP-1 therapies representing one of the fastest-growing segments in the global pharmaceutical market, these results demonstrate that AI can now generate not only predictive but functionally validated peptide drugs, paving the way for rapid expansion into adjacent therapeutic areas using the same HYFT-driven approach.

“This is not a one-off success,” said Dr. Jennifer Bath, CEO of ImmunoPrecise. “We’ve demonstrated a scalable, first-principles mechanism to design potent, stable, and biologically active peptide therapeutics. HYFT-guided design unlocks repeatable workflows for other validated targets—whether in cardiometabolic disease, oncology, or infectious disease. It represents a foundational shift in how therapeutics are discovered. The same LENSai-driven approach has already transformed our vaccine and antibody discovery programs, and we are now applying that rinse-and-repeat methodology to metabolic diseases—starting with GLP-1.”

IPA is now considering two complementary preclinical paths for its lead GLP-1 candidates:

The sequences were also engineered for compatibility with next-generation expression systems, including nucleic acid-based vectors, which support scalable expression in both traditional and emerging human-relevant models, aligning with evolving regulatory interest in more predictive, flexible, and efficient therapeutic development approaches.

The significance of this breakthrough extends far beyond GLP-1. The same AI framework and HYFT-driven approach that generated these potent peptide drugs can now be applied to other high-value therapeutic targets—quickly, efficiently, and with built-in biological relevance.

This announcement follows IPA’s recent success with AI-designed dengue virus vaccine candidates, reinforcing the broad applicability of its technology across both infectious and non-infectious diseases.
