ToxoTech and AAX Biotech and Join Forces to Advance Next-Generation Biotherapeutics

The co-development study combines AAX Biotech’s proprietary Seqitope® platform with ToxoTech’s expertise in biologic drug design to create novel biotherapeutic candidates with improved potency and precision. By applying Seqitope® to optimize receptor recognition, the collaboration aims to generate novel variants with potential as treatments for neuromuscular and neurological indications. 

“At ToxoTech, we bring extensive experience in the drug design of biotherapeutics for neurology, and we see Seqitope® as a valuable complement to our discovery pipeline. Working together with AAX Biotech allows us to accelerate the development of innovative therapies with the potential to transform treatment options across neurological and neuromuscular indications”, says Geoffrey Masuyer, CEO of ToxoTech. 

“This project represents an exciting new application of Seqitope® beyond its established use in antibody epitope mapping,” says Daniel X. Johansson, CEO/CSO of AAX Biotech. “With our cutting-edge technologies to advance biologic drug discovery, we are pleased to collaborate with ToxoTech and leverage Seqitope® to guide rational design and accelerate the development of precision-engineered biologics.” 

This partnership reflects a shared vision between the two companies to accelerate the development of precision biologics and broaden future treatment options. By integrating Seqitope®’s high-resolution insights with ToxoTech’s innovative therapeutic approach, the project aims to open new avenues in the creation of advanced therapies.
