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.”
Long-term extension data presented at the Alzheimer’s Association International Conference showed amyloid plaque reaccumulation remained slow at up to 2.5 years of follow-up in patients who were taken off of treatment with Eli Lilly’s anti-amyloid antibody.
Long-term data presented at the Alzheimer’s Association International Conference show Leqembi can help patients stay in the earlier stages of Alzheimer’s disease as compared to the condition’s natural progression.
In a Phase Ib/IIa trial, 91% of patients receiving the highest dose of trontinemab were amyloid negative after seven months of treatment, representing what B. Riley Securities called a “paradigm shift” to first-generation FDA-approved antibodies.
Acknowledging the limits of disease-modifying drugs like Leqembi and Kisunla, companies like Bristol Myers Squibb, Acadia, Otsuka and Lundbeck are renewing a decades-old search for symptomatic treatments, including in high-profile drugs like Cobenfy.
A retrospective cohort study found that semaglutide and tirzepatide are linked with significantly lower risks of dementia and stroke, hinting at potential neuroprotective effects of GLP-1 therapies.
The patient, who was being treated with an investigational gene therapy for limb-girdle muscular dystrophy, died of acute liver failure, the same complication responsible for the deaths of two boys taking Sarepta’s Duchenne muscular dystrophy treatment Elevidys.
Participants in trials of BrainStorm Cell Therapeutics’ NurOwn filed a Citizens’ Petition with the FDA earlier this month seeking a new review of the stem cell therapy that was rejected in 2022 based on real-world data and 90% survival in an expanded access program.
The FDA will allow a new dosing schedule for Eli Lilly’s Alzheimer’s drug Kisunla that could lessen a known side effect of the monoclonal antibody drug class that has led to several deaths.
Armed with the latest biological knowledge and cutting-edge computational techniques—and, of course, investor dollars—these six biotechs are playing in the largely underappreciated longevity space, developing therapies that may improve the quality of aging.
