• ABL and SANOFI to collaborate on the development of ABL301, a potential first-in-class bispecific antibody targeting alpha-synuclein and containing a proprietary brain shuttle, for alpha-synucleinopathies, including Parkinson's disease
• ABL301 uses ABL's Grabody-B platform technology to effectively cross the blood-brain barrier
• ABL to receive $75M upfront and up to $985M in potential milestone payments for exclusive global license to ABL301

ABL Bio, Inc. (KOSDAQ: 298380), a clinical-stage biotech developing bispecific antibody technology for immuno-oncology and neurodegenerative diseases, today announced an exclusive collaboration and worldwide license agreement with SANOFI to develop and commercialize ABL301, a pre-clinical stage bispecific antibody targeting alpha-synuclein and IGF1R to treat Parkinson's disease and other potential indications with enhanced blood-brain barrier (BBB) penetration.

Under the terms of the agreement, ABL will receive $75 million in upfront payments. In addition, ABL is eligible to receive up to $985 million based on the achievement of predefined development, regulatory and commercialization milestones, including $45 million in near-term milestones. ABL is also eligible to receive royalties on net sales if the product from the collaboration is commercialized. The transaction will become effective after customary closing conditions are met, such as the HSR clearance.

SANOFI will receive worldwide exclusive development and commercialization rights to ABL301. Meanwhile, ABL will lead the preclinical development and Phase 1 clinical trial of ABL301. Thereafter, SANOFI will be responsible for further clinical development, regulatory approval and commercialization of ABL301 worldwide.

Grabody-B is a BBB shuttling platform that targets the insulin-like growth factor 1 receptor (IGF1R) to maximize BBB penetration of potential therapies for various CNS-related diseases. Utilizing Grabody-B technology, ABL301 effectively carries the anti-alpha-synuclein antibody across the BBB to enhance therapeutic efficacy against Parkinson's disease.

"This groundbreaking partnership with SANOFI proves the immense possibilities of ABL's innovative bispecific antibody technology." said Sang Hoon Lee, PhD, CEO of ABL Bio. "We will continue to develop our Grabody-B platform and expand its applicability in other neurodegenerative diseases, such as Alzheimer's, to contribute to improving the lives of patients worldwide."
