LONDON (AP) — Britain’s drug regulator authorized the Alzheimer’s drug Leqembi on Thursday, saying it's the first medicine to show some impact in slowing the progression of the neurodegenerative disease. But the U.K.

government likely won’t be paying for it after an independent agency separately issued draft guidance concluding that the benefits of Leqembi “cannot be considered good value for the taxpayer.” In addition to the cost of the drug, providing Leqembi requires that patients be hospitalized every two weeks to receive it and be closely monitored for side effects. Experts also noted the lack of data regarding the long-term effectiveness of Leqembi, made by Japanese drugmaker Eisai.

“The reality is that the benefits this first treatment provides are just too small to justify the significant cost,” said Dr. Samantha Robers, chief executive of the National Institute for Health and Care Excellence, or NICE. The draft guidance issued by NICE will now be open for public consultation and all responses will be considered at a second meeting later this year before final advice is issued.

The agency estimated about 70,000 people in Briton might benefit from Leqembi. The drug is still available to be prescribed if patients pay for it privately. In the U.

S., it costs about $26,000 per patient per year. Some experts said that while they understood patients and their families might be disappointed by the news, there was hope better drugs might be developed soon.
