of Leqembi for the treatment of Alzheimer’s disease (AD).

This is the first approved medication proven to slow the

progression of AD’s clinical symptoms. A phase three trial

among 50- to 90-year-old patients with early AD showed

that it can do so by about 27% over an 18-month period.

While we cannot extrapolate(推断) beyond 18 months,

this represents about a six-month delay in progression of

AD symptoms.A second disease-slowing drug, donanemab,

has recently shown similar effects and may get FDA

69approval by the end of the year. The development of

Leqembi is a notable success for medical science in that a

disease previously impervious to any disease-modifying

medical intervention now has an available, effective

treatment. However, paraphrasing Winston Churchill,

this is not the beginning of the end but the end of the

beginning. The drug does not reverse disease symptoms

or prevent progression, it slows progression. And there

are considerations that make it inappropriate for many

patients with AD. It does, however, lay the groundwork

for future AD medications that could alleviate(减轻)

suffering from this devastating disease for generations to

important factor for new drugs is their cost.

Leqembi’s price tag is $26,500 per year—much more

than the current symptomatic medications for AD but

comparable or less expensive than new medications for

other conditions, for example multiple sclerosis or re has announced that it will provide coverage

for this medication, although it is requiring that physicians

perform certain clinical measures and enter the patient’s

data in a registry in order for the drug to be covered, which

will increase physician and patient burdens. What’s more,

traditional Medicare only covers 80% of outpatient costs,

so for those patients without supplemental insurance, a

20% copay for the drug and required MRI scans(核磁共振扫描) might amount to up to $10,000 or more per year

of in a nursing home.（材料来自CNN网站，有删改）1. What can we learn from the first two paragraphs?A. Leqembi can make a six-month delay of AD’s
