AbbVie acquires Aliada Therapeutics and with it Alia 1758

"Neuroscience is one of our key growth areas and we are committed to driving innovation in this field to address critical unmet needs for patients living with seriously debilitating neurological diseases such as Alzheimer's disease," said Roopal Thakkar, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "This acquisition immediately positions us to advance ALIA 1758, a potentially best-in-class disease-modifying therapy for Alzheimer's disease. In addition, Aliada's novel BBB-crossing technology strengthens our R&D capabilities to accelerate the development of next-generation therapies for neurological disorders and other diseases where enhanced delivery of therapeutics into the CNS is beneficial." Our proprietary MODEL platform has enabled the development of ALIA 1758, a promising step forward in brain delivery of an anti-amyloid antibody therapy," said Michael Ryan, M.D., chief medical officer at Aliada Therapeutics. "Many promising CNS-targeted therapies fail to reach late-stage trials due to their inability to cross the blood-brain barrier. Our MODEL platform addresses this challenge directly, efficiently delivering targeted drugs and potentially transforming how we treat neurological diseases." Aliada is advancing therapeutic candidates using its Modular Delivery (MODEL) platform, engineered for high-precision CNS drug delivery. The novel BBB-crossing technology targets transferrin and CD98 receptors (TfR and CD98) which are highly expressed in brain endothelial cells. By engineering highly optimized TfR or CD98 binders, this platform is designed to deliver different types of biological cargoes into the brain, including therapeutic antibodies and genetic medicines such as siRNA. ALIA 1758 utilizes TfR to transport a 3pE-A beta antibody across the BBB to enable degradation and elimination of amyloid beta plaques, a pathological hallmark of Alzheimer's disease. This investigational candidate is currently in a Phase 1 clinical trial to assess its safety and tolerability in healthy participants (NCT06406348).
