Europe approves Leqembi for select Alzheimer's patients
From my colleague Andrew Joseph: After a bumpy road, Eisai and Biogen's Alzheimer's therapy Leqembi has won approval in Europe.
The authorization, announced yesterday by the European Commission, came after regulators initially recommended against the therapy's approval, citing the modest benefits — it can only partially slow the cognitive and functional decline caused by the disease — and the serious side effect risks that come with the treatment. But after an appeal, regulators revised their recommendation, saying that the benefits of Leqembi outweigh the risks for select patients, specifically those who do not have genetic variants that leave them at higher risk for the brain bleeding and swelling that medicines like Leqembi can cause.
The commission's approval was limited to the narrower patient group.
The back-and-forth reflects how regulators around the world are taking different approaches as they weigh the new class of Alzheimer's therapies that includes Leqembi. The medicines are the first that have shown they can slow disease progression, but only in a limited way. The brain issue they can cause — what's known as ARIA — can in rare cases be fatal. Notably, European regulators last month recommended against the approval of another, similar treatment, Eli Lilly's Kisunla. Both therapies are approved in the U.S.

House calls on 23andMe's Anne Wojcicki to testify
House Oversight Chair James Comer said yesterday that he was launching an investigation into national security and data privacy concerns stemming from the bankruptcy of 23andMe, whose collapse has prompted fears that the DNA data of millions of Americans could fall into the wrong hands — specifically the Chinese Communist Party.
The company filed for bankruptcy after a failed attempt by co-founder Anne Wojcicki to buy it back.
In a public letter, Comer is calling for Wojcicki to testify publicly on May 6.
"National security concerns about 23andMe and similar companies are not new," Comer wrote.
