Why a new Alzheimer's drug is having a slow US debut

The first drug to show that it slows Alzheimer’s is on sale, but treatment for most patients is still several months away.

Two big factors behind the slow debut, experts say, are scant insurance coverage and a long setup time needed by many health systems.

Patients who surmount those challenges will step to the head of the line for a drug that delivers an uncertain benefit. Here’s a closer look.

THE SITUATION

The U.S. Food and Drug Administration approved Leqembi, from Japanese drugmaker Eisai, in early January. It's for patients with mild or early cases of dementia tied to Alzheimer’s disease.

Regulators used the FDA’s accelerated pathway, which allows drugs to launch before they’re confirmed to benefit patients. In studies, Leqembi modestly slowed the fatal disease, but doctors aren't sure yet how that translates into things like greater independence for patients.

Patients get the drug by IV every two weeks. Eisai says the company has shipped Leqembi to U.S. specialty drug distribution centers. From there, it can be delivered overnight to hospitals or medical centers.

Eisai spokeswoman Libby Holman said prescriptions for the drug have been written, and they expect patients to start receiving it “very soon.”

COST AND COVERAGE

A year’s treatment will run about $26,500. Patients who can afford that without insurance will be able to start the treatment if they are deemed a candidate for Leqembi and they find a doctor and health care system prepared to help them.

There are currently few options outside self-pay. Most of the patients who may be candidates for this drug are on Medicare, and the federal program's coverage is narrow so far. It has said it will cover treatments like Leqembi only for patients enrolled in certain research trials designed to test the drug.
