Luxna Deepens Collaboration with BioSpring to Advance Therapeutic Oligonucleotide Development

Osaka, Japan, December 2nd, 2025 - Luxna Biotech Co., Ltd. (President CEO: Hideaki Sato; Headquarters: Suita-shi, Osaka, Japan, hereinafter “Luxna”) and one of the largest contract development and manufacturing organizations (CDMO) specializing in oligonucleotide therapeutics, BioSpring GmbH (CEO: Dr. Sylvia Wojczewski; Headquarters: Frankfurt am Main, Germany, hereinafter “BioSpring”) announced a new collaboration.

In this new project, Luxna will advance an oligonucleotide therapeutic for an undisclosed target, while BioSpring contributes its expertise in process development, analytical characterization, and clinical manufacturing of oligonucleotides.

This expands the recently announced partnership between Luxna and BioSpring, furthering the translation of Luxna’s proprietary XNA amidite chemistry into therapeutic oligonucleotides.

Supporting Luxna not only in manufacturing, but also in the development and scale-up of complex oligonucleotide candidates underscores BioSpring’s role as an enabler for innovative biotech and pharma programs. Together, Luxna and BioSpring aim to accelerate the path from concept to clinic and ensure reliable supply for future clinical and commercial needs.

Mr. Hideaki Sato, President and CEO, Luxna Biotech:

“This project marks the next step in translating Luxna’s XNA technology into therapeutic development. Together with BioSpring, we are accelerating the path toward clinical application while reinforcing our commitment to bringing new treatment options to patients.”

Dr. Sylvia Wojczewski, CEO, BioSpring:

We are proud that Luxna has selected BioSpring to support its therapeutic programs based on its XNA technology. This technology presents novel opportunities for advancement in therapeutic innovation in the oligonucleotide field.

About Luxna XNAs Technology  

Luxna XNAs Technology collectively means an innovative nucleic acid group of AmNA™, scpBNA™, GuNA™ and 5’-CP™ originated in Professor Obika’s laboratory at the Osaka University Graduate School of Pharmaceutical Sciences, Bioorganic Chemistry.
