JCR Pharmaceuticals (JCRRF) announced that Acumen Pharmaceuticals (ABOS) exercised its exclusive option to develop, manufacture, and commercialize, on a global basis, up to two candidates for development in the treatment of Alzheimer's disease, enabled by JCR's proprietary blood-brain barrier-penetrating technology platform, J-Brain Cargo. The partnership, announced in July 2025, focuses on developing a BBB-penetrating treatment for AD that combines JCR's J-Brain Cargo with Acumen's amyloid beta oligomer-selective antibodies, which target toxic soluble AbetaOs, a key pathological driver in the onset and progression of AD. The collaborative program aims to demonstrate the feasibility of applying J-Brain Cargo in delivering sabirnetug, Acumen's targeted immunotherapy drug candidate, and other AbetaO-selective antibodies across the BBB to slow the progression of AD pathology. Earlier this year, Acumen presented non-clinical data from a mouse model of AD at the International Conference on Alzheimer's and Parkinson's Diseases and Related Neurological Disorders, which demonstrated that using AbetaO-selective antibodies with J-Brain Cargo technology increased brain exposure while preserving target engagement as demonstrated by AbetaO selectivity. Acumen plans to file an investigational new drug application for this program in mid-2027. Under the terms of the agreement, JCR will receive an option payment with Acumen's decision to exercise its exclusive option to develop, manufacture, and commercialize, on a global basis, up to two candidates from the collaboration. JCR will also be eligible to receive future milestone payments of up to $40M related to development, and up to $515M related to sales, for a total of up to $555M. In addition, JCR is entitled to receive tiered royalties based on net sales for any products that emerge from the collaboration.

About ABOS
Acumen Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company. The Company is engaged in developing a disease-modifying approach to target underlying cause of Alzheimer's disease (AD). The Company is focused on advancing a targeted immunotherapy drug candidate, sabirnetug (ACU193), in its Phase II ALTITUDE-AD clinical trial following Phase I results in early AD patients (patients with mild cognitive impairment or mild dementia due to AD). Sabirnetug is a recombinant humanized immunoglobulin gamma 2 (IgG2), monoclonal antibody (mAb) that selectively targets the anti-amyloid-beta oligomer, has demonstrated functional and protective effects in in-vitro assays, and has demonstrated in-vivo safety and pharmacologic activity in multiple animal species including transgenic mouse models for AD. The Company is developing sabirnetug for IV administration once every four weeks (Q4W) for the treatment of early AD, and it has developing sabirnetug for subcutaneous administration.
