Reverse decline trials

Bredesen is optimistic that the research could mean life-changing treatments for dementia patients in the future. We need to look deeply into this, analyse it, and then target those things.

Still, the prospect of limited coverage is a blow to Biogen, which had hoped to scale up the number of patients on the drug in Under the draft rules, Medicare would only cover Aduhelm if patients 1 are enrolled in randomized, controlled clinical trials, 2 have been diagnosed with mild forms of cognitive impairment and 3 have evidence of the amyloid plaques that Aduhelm is designed to clear away from the brain.

This means that only patients with access to large medical centers that have the resources to run clinical trials and diagnostics would be able to begin treatment with Aduhelm. Coverage with evidence development CED under a randomized clinical trial will exclude almost all patients who may benefit," Biogen said in a statement emailed to the Business Journal. We will continue to urge CMS to align Medicare coverage for the class of amyloid-directed therapies with the populations studied in the respective clinical trials and guided by expert recommendations for appropriate use.

Aduhelm was greenlit by the U. Food and Drug Administration in June last year via a path called accelerated approval. Essentially, the FDA acknowledged in its approval that while it believes Aduhelm will ultimately provide a clinical benefit, there is still some uncertainty.

The uncertainty stems from a disconnect between what the drug is designed to do — clear plaques of amyloid beta proteins from the brain — and limited evidence that clearing those plaques can actually prevent or reverse cognitive decline in Alzheimer's patients. The confusion has driven slower-than-expected uptake of the drug. Bikle, D.
