AATec Medical and Northway Biotech Announce Partnership to Develop Industrial Production Process for ATL-105 Targeting Lung Disease

• Partnership established to develop and scale production of ATL-105, a novel recombinant version of alpha-1 antitrypsin

• Lead indication is non-CF bronchiectasis; ATL-105 targets disease drivers through a broad multimodal mechanism of action

VILNIUS, LT / ACCESS Newswire / July 15, 2025 / AATec Medical GmbH ("AATec"), a biotech company developing a multi-product platform for the treatment of respiratory diseases, and Northway Biotech ("Northway Biotech" or "NBT"), a global Contract Development and Manufacturing Organization (CDMO), today announced a partnership for manufacturing process development and analytical development of AATec's lead product candidate, ATL-105, a proprietary, inhaled therapy based on recombinant alpha-1 antitrypsin (AAT) for non-cystic fibrosis bronchiectasis (NCFB).

Under the agreement, Northway Biotech will leverage its expertise in biologics manufacturing to develop and scale the production process for ATL-105 using the Pichia pastoris expression system.

"With this partnership, we are establishing a robust and scalable production process for ATL- 105, laying the foundation for consistent quality for clinical development and commercial use," says Rüdiger Jankowsky, PhD, co-founder and CEO of AATec, and adds: "ATL-105 represents a new generation of inhaled biologics, combining anti-protease, anti-inflammatory, and antiinfective properties in one molecule. Delivered directly to the lungs, it enables fast, targeted action with minimal systemic exposure. We believe ATL-105 can redefine care in respiratory diseases with high medical need, such as non-CF bronchiectasis."

"We are excited to support AATec in progressing towards clinical trials", shares Prof. Vladas Algirdas Bumelis, CEO and Chairman of Northway Biotech. "AATec is advancing a promising therapeutic solution addressing significant unmet medical needs, supported by a highly capable and dedicated team. With our decades of expertise in microbial systems, we are well-positioned to scale this program efficiently and deliver quality at every step."

"We have recognized the opportunity to support a program that could meaningfully advance care for patients with respiratory diseases," adds André Markmann, PhD, VP of Business Development at Northway Biotech. "Inhaled protein therapies are gaining significant traction, and ATL-105 stands out as one of the most promising approaches in this area."

AATec develops ATL-105 to treat NCFB, a chronic inflammatory respiratory condition which affects millions of people worldwide. This debilitating disease is marked by dilated bronchi, persistent inflammation, frequent airway infections and impaired mucus clearance. In addition to NCFB, ATL-105 has therapeutic potential for a broader range of inflammatory and infectious respiratory diseases, such as COPD, ARDS and other indications, reflecting the versatility of its anti-inflammatory, immunomodulatory, and anti-infective properties.
