Boehringer Ingelheim has secured exclusive worldwide rights to develop a potential first-in-class small molecule treatment for autoimmune diseases through a licensing agreement with Japanese pharmaceutical company Kyowa Kirin. The deal, announced on October 30, 2025, represents a significant expansion of Boehringer Ingelheim's autoimmune disease pipeline and addresses a critical area of unmet medical need.
Strategic Partnership Targets Global Health Challenge
The licensed pre-clinical program aims to address the substantial burden of autoimmune diseases, which affect approximately one in ten people worldwide and impose significant challenges on patients and healthcare systems. Despite therapeutic advances, there remains a high need for more effective and long-lasting treatment options for these conditions.
"Our commitment to delivering life changing therapies for patients with autoimmune diseases is unwavering. We are pleased to add a potential first in class program to our growing pipeline," said Carine Boustany, US Innovation Unit Site Head and Global Head of Immunology and Respiratory Diseases at Boehringer Ingelheim.
