Alzheimer’s disease
Johnson & Johnson will discontinue the Phase II Auτonomy study of posdinemab after a scheduled review found the anti-tau antibody failed to slow clinical decline in patients with early Alzheimer’s disease.
Analysts agree that the failure of Novo Nordisk’s semaglutide to reduce Alzheimer’s disease progression removes a “modest” or “perceived” overhang on Biogen and the anti-amyloid antibody class in general, clearing the way for increased uptake of Leqembi and Eli Lilly’s Kisunla.
“We felt we had a responsibility to explore semaglutide’s potential, despite a low likelihood of success,” Martin Holst Lange, Novo’s R&D chief, said on Monday.
To expand the population for the anti-amyloid Alzheimer’s drugs, Lilly and Biogen are testing presymptomatic patients. Will doctors be open to this paradigm-shifting change?
Elecsys’ approval could help boost the uptake of currently approved Alzheimer’s disease therapies, including Biogen’s Eisai-partnered Leqembi, with CEO Chris Viehbacher recently noting that such biomarker-based tests could “remove some of the bottlenecks” in uptake.
MapLight laid out the terms of its planned IPO in a regulatory filing on Monday, providing greater detail about what the funds will be used for.
VectorY Therapeutics will evaluate the use of SHP-DB1, a capsid developed by Shape Therapeutics, to deliver therapies to the brain, including VectorY’s developmental Huntington’s and Alzheimer’s disease treatments.
While the approval of Leqembi Iqlik bodes well for Biogen and Eisai’s planned application for a subcutaneous induction regimen next year, its financial impact remains “uncertain,” as potentially higher revenues from the injection could be offset by steeper costs of production, according to Jefferies.
In another blow to Prothena’s neurodegenerative disease portfolio, anti-amyloid candidate PRX012 has run into the same problem that larger peers Biogen and Eli Lilly have battled: high rates of swelling in the brain.
Arguably the FDA’s most anticipated decision this month is for a subcutaneous induction formulation of Biogen and Eisai’s Alzheimer’s drug Leqembi, which, according to Eisai, could “help reduce the burden on healthcare professionals and patients.”
