Asahi Kasei Pharma and Alchemedicine Advance a Novel Therapeutic Candidate Into Phase I Study for the Treatment of Refractory Diseases

TOKYO--(BUSINESS WIRE)--Asahi Kasei Pharma, a global provider of healthcare and pharmaceutical solutions, in collaboration with Alchemedicine, has announced that its novel Endothelin A (ETA) receptor antagonist AK1960 has advanced to a Phase I clinical study following a successful preclinical phase. AK1960 is expected to be used in the treatment of various refractory diseases—medical conditions resistant to standard therapies. The initiation of a Phase I study is considered a significant step toward growing Asahi Kasei’s healthcare impact.

AK1960 is a small molecule with a new core structure derived from Alchemedicine’s HiSAP™¹ platform. It exhibits high selectivity, potent inhibition for the ETA receptor and has demonstrated efficacy in animal models for kidney diseases. AK1960 is expected to contribute to the treatment of various diseases which are difficult to control, such as refractory chronic kidney disease.

In 2022, Asahi Kasei Pharma and Alchemedicine entered into an exclusive license agreement, with Asahi Kasei Pharma acquiring worldwide rights to develop and commercialize Alchemedicine’s ETA receptor antagonist. While preclinical and Phase I studies are performed in Japan, the program is intended for the global market. The Asahi Kasei Group will leverage Calliditas Therapeutics AB and Veloxis Pharmaceuticals, Inc. to advance the development of AK1960.

“The advancement of AK1960 into a Phase I study reflects an important milestone for Asahi Kasei Pharma and demonstrates our close collaboration with Alchemedicine to address unmet medical needs,” said Yasuo Nakamura, Director and Senior Executive Officer at Asahi Kasei Pharma. “Since 2022, we have worked to overcome technical challenges, validate the therapeutic concept, and prepare for clinical evaluation. By leveraging the expertise of Calliditas and Veloxis in therapeutic development, we will continue advancing AK1960. Together, we are building a system that demonstrates scientific excellence while creating meaningful impact for real-world health settings.”

Asahi Kasei positions Pharmaceuticals as a First Priority business in its medium-term management plan, emphasizing value creation by advancing high-impact therapies to address unmet medical needs globally. Recent examples of these activities include the start of Phase III study of ART-123 (Recomodulin™) in Japan for CIPN and the inclusion of TARPEYO® in the updated KDIGO Clinical Practice Guidelines. The initiation of a Phase I study for AK1960 reflects the company’s commitment to enhancing its Healthcare sector and pharmaceutical R&D capabilities intended to drive long-term, sustainable growth.
