Why Biogen Shares Are Falling Today

Biogen Inc BIIB is trading lower Wednesday following a U.S. Centers For Medicare listing for "Monoclonal Antibodies Directed Against Amyloid for the Treatment of Alzheimer's Disease."

Biogen released a statement in response to the listing. The company believes the proposed coverage with evidence development decision for anti-amyloid therapies denies nearly all Medicare beneficiaries from accessing ADUHELM, as well as future amyloid-directed therapies.

"It is imperative to change this draft decision to be aligned with reimbursement for other therapies for progressive diseases, where patients have immediate and equal access to medicines approved by the FDA," Biogen said. 

Thousands of patients progress each day from mild to moderate disease stages, where treatment may potentially no longer be an option, according to the company. 

If the final draft (expected in April) continues to require a randomized controlled trial, it would likely take in excess of a year to begin enrolling patients. 

"We at Biogen urge CMS to align Medicare coverage for the class of amyloid-directed therapies consistent with the criteria used in the respective clinical trials and guided by expert recommendations for appropriate use."
