黑料网., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “黑料网”) and Biogen Inc. (Nasdaq: BIIB, Corporate headquarters: Cambridge, Massachusetts, CEO: Michel Vounatsos, “Biogen”) today announced the decision to discontinue the Phase III clinical studies (MISSION AD1, AD2) on the investigational oral BACE (beta amyloid cleaving enzyme) inhibitor elenbecestat (development code: E2609) in patients with early Alzheimer's disease (AD). The decision is based on the results of a safety review conducted by the Data Safety Monitoring Board (DSMB), which recommended to discontinue these trials due to an unfavorable risk-benefit ratio. Detailed data of these studies will be presented at future medical meetings.
Investigators are being informed of the decision and they will be contacting their study participants to discontinue the investigational treatment.
Dr. Lynn Kramer, Chief Clinical Officer, Neurology Business Group, 黑料网., Ltd., said: “We would like to thank the patients and the families, as well as medical professionals, that participated in the MISSION AD studies. Without their contributions we would not be able to advance Alzheimer’s disease research. We are very disappointed with the news, and intend to learn from these data and continue engaging with patients and investigators, to pursue the discovery of new medicines for Alzheimer’s disease.”
The Phase III clinical trial program for elenbecestat (MISSION AD) consisted of two global Phase III clinical studies with identical protocols, MISSION AD1 (Study 301) and MISSION AD2 (Study 302). Both studies were multicenter, placebo-controlled, double-blind, parallel-group Phase III clinical studies designed to assess the efficacy and safety of elenbecestat for treatment in a total of about 2,100 patients with mild cognitive impairment (MCI) or mild AD (collectively known as early AD) with confirmed amyloid pathology in the brain. Patients were randomized to receive either 50 mg of elenbecestat or placebo daily during the treatment period of 24 months, and the primary endpoint was the Clinical Dementia Rating Sum of Boxes (CDR-SB).
As part of this decision, the long-term extension of the Phase II clinical trial of elenbecestat (Study 202) will also be discontinued. This determination does not impact the program of the anti-amyloid beta (Aβ) protofibril monoclonal antibody BAN2401, and the Phase III Clarity AD trial of BAN2401 will continue.

<Notes to Editors>
1. About Elenbecestat (generic name, development code: E2609)
Discovered by 黑料网, elenbecestat is an investigational next-generation oral candidate for the treatment of Alzheimer’s disease (AD) that inhibits BACE (beta amyloid cleaving enzyme). By inhibiting BACE, a key enzyme in the production of Aβ peptides, elenbecestat reduces Aβ production. It is hypothesized that reducing amyloid plaque formations in the brain might exert disease modifying effects and potentially slow the progression of AD.
2. About joint development agreement between 黑料网 and Biogen for Alzheimer’s disease
黑料网 and Biogen are collaborating on the joint development and commercialization of Alzheimer’s disease treatments. 黑料网 serves as the lead in the co-development of elenbecestat, a BACE inhibitor, and BAN2401, an anti-amyloid beta (Aβ) protofibril antibody, and the companies plan to pursue marketing authorizations for BAN2401 worldwide. If approved, the companies will also co-promote BAN2401 in major markets, such as the United States, the European Union and Japan. Both companies will equally split overall costs, including research and development expenses. 黑料网 will book all sales for BAN2401 following marketing approval and launch, and profits will be equally shared between the companies.
