In the weeks since a new Alzheimerās drug was approved, hopeful patients have bombarded Dr. Alireza Atri with calls and emails about a treatment that has sparked both excitement and scepticism. They want to know if the drug might be right for them. Like many physicians, Atri has no easy answers.
āItās not a simple yes or no,ā said the neurologist at the Banner Sun Health Research Institute in Arizona.
It probably wonāt be for a while. Doctors across the country are still trying to figure out who should receive the drug called Aduhelm, which, at best, slows the fatal disease marginally. Other drugs for Alzheimerās disease only temporarily ease symptoms like memory problems, insomnia and depression. While some clinics have already started giving the drug, many providers say it will take weeks or months before they are ready. Insurers ā including the biggest bill payer for this drug, Medicare ā still need to determine which patients to cover for a treatment that could cost more than $50,000 a year. And doctors worry that emotions will affect decisions by patients and families in seeking the drug.
āPeople are desperate. Itās a really horrible disease,ā said Stanford Universityās Dr. Michael Greicius.
Karl Newkirk hopes to start taking Aduhelm if his doctor gives the OK because he doesnāt see any other treatments worth trying.
āIt looks like the only star in the sky,ā said the 80-year-old Sarasota, Florida, resident, who has early-stage Alzheimerās.
Newkirkās doctor confirms heās a good candidate for the drug. While the retired technology consultant is still fit enough to ride roller coasters with his grandchildren at nearby Busch Gardens, he struggles with short-term memory loss. He wants to try Aduhelm, even though heās aware of the drugās limits. Michele Hall, 54, of Bradenton, Florida, also is eager to discuss the drug at her next appointment with an Alzheimerās specialist. A former government attorney, Hall had to quit her job after struggling with once-simple tasks like spelling, public speaking and remembering deadlines. She was diagnosed with early Alzheimerās last November by doctors at the Mayo Clinic.
Hall calls Aduhelm āthe first tiny glimmer of hopeā that sheāll get more quality time with her husband and their three adult children.
āWhen you get that diagnosis, you really wake up every morning and go āHere I am, itās ticking away and Iām just waiting,'ā she said. āWell, now you have something to look forward to.ā
Biogenās Aduhelm is the first Alzheimerās medication in nearly 20 years. Its Food and Drug Administration approval earlier this month triggered a swift backlash from many experts, including the agencyās own outside advisers who had warned that its supposed benefit relied on flimsy data. Three resigned over the FDAās decision. Aduhelm does not reverse mental decline. It only slowed it in one study that was marred by hard-to-interpret results. The data were so murky that the FDA ultimately granted the drug conditional approval based on a different measure: its ability to get rid of harmful clumps of plaque in the brains of patients with early forms of the disease.
The FDA approval isnāt limited to those early patients. Anyone with Alzheimerās ā at least theoretically ā could get prescribed the drug. But advocacy groups like the Alzheimerās Association and many doctors say the focus should be on patients with an early diagnosis, like those who helped in the study.āI donāt want to see people pull their mothers from nursing homes to get this treatment,ā said Dr. Babak Tousi, a Cleveland Clinic geriatrician who consulted with Biogen and helped run one of the testing sites for Aduhelm. Safety will be a key consideration, according to Dr. Ronald Petersen at the Mayo Clinic, which is coming up with its own use guidelines for the drug.āWe want to be conservative here,ā said Petersen, an Alzheimerās specialist who has consulted with most major drugmakers in the field, including Biogen.
About 40% of patients getting the full drug dose in Biogenās studies had swelling or tiny bleeds in the brain. While the side effects usually resolved, in rare cases they led to more severe bleeding that could potentially cause brain injury or other dangerous complications. Monitoring patients on the drug involves regular brain scans. Thatās on top of a different type of scan to tell if patients have the brain plaque targeted by the drug. Running all those tests could easily approach $10,000 the first year, according to physicians. Insurers will likely require prior approval of those scans, which could delay care. And depending on coverage, patients still might be liable for thousands of dollars annually from the scans and treatments due to deductibles and other out-of-pocket costs. Biogen says about 900 sites in the U.S. have the equipment and expertise to immediately begin giving the drug, which requires monthly IVs.
The private Michigan Institute for Neurological Disorders has already started treating early-stage Alzheimerās patients. The institute said it will pick up most of the cost if an insurer ultimately denies coverage ābecause itās a therapy we believe in,ā a spokeswoman said. Meanwhile, Stanfordās Greicius, a neurologist and Alzheimerās specialist, has no plans to prescribe Aduhelm.
āI donāt think thereās sufficient evidence that it works, and thereās plenty of evidence that it can harm patients,ā he said.
He said he plans to lay out a ācompelling and compassionateā case for why he doesnāt want to give patients the medicine. But he worries that some patients may simply turn to a doctor who will provide it. The Cleveland Clinicās Tousi said talking about expectations, cost and the side effects may counter some emotional pressure to give the drug to patients not suited for it. But part of the challenge is family members often think a patient is in an earlier stage of the disease than they actually are. He said they have to understand that the medication will not bring someone back to who they were.
āWhat we wish cannot always be translated to real life,ā he said.
One likely consequence of Aduhelmās approval is earlier screening and diagnosis for Alzheimerās, a longtime aim of those who study the disease, given that it develops slowly over years or decades. But an earlier diagnosis combined with Aduhelmās incremental benefit may simply prolong the hardships of caring for someone with Alzheimerās.
āIt could turn out that it actually increases your caregiver burden if itās just slowing things down a little bit,ā said Dr. Suzanne Schindler of Washington University in St. Louis. āI think itās going to be really disappointing for a lot of people.ā
