Eric Widera 0:01

Welcome to the Jerry Powell podcast. This is Eric Radera. This

is Alex Smith.

Eric Widera 0:05

And Alex, who do we have with us today?

Alex Smith 0:07

We're delighted to welcome back to the Jerry Pal podcast, Jason Carlovish, who is professor at the University of Pennsylvania School of Medicine, co director of the Penn Memory Center, and Associate Director of the Alzheimer's Disease Research Center and author of the problem of Alzheimer's Disease. Welcome. Back. to the Jerry Powell podcast, Jason.

Jason Karlawish 0:25

Great to be back. Alex and Eric. Thanks so much for having me on.

Alex Smith 0:29

And we're delighted to welcome back Sharon Brangman, who is a SUNY Distinguished Service Professor and Chair of the Department of Geriatrics and Director of the Center of Excellence for Alzheimer's Disease. Welcome back to JerryPal Podcast, Sharon.

Sharon Brangman 0:43

Thank you for having me again.

Alex Smith 0:45

And we're delighted to welcome Nate Chin, who is associate professor at the University of Wisconsin, where he's medical director of their Alzheimer's Disease Research Center. And runs a large study in Wisconsin called the Rap Study, studying Alzheimer's disease. And he's

Eric Widera 1:00

Yeah. Well he is the host of my favorite dementia podcast, Dementia Matters. If you haven't checked out that podcast, please do. Dementia Matters, just type it into your favorite podcasting app and it's the first one that pops up.

Jason Concepcion 1:15

I can't believe we have another

Eric Widera 1:16

podcasting host. So we got an exciting episode today. I think the general theme of this is going to be what's the geriatrician's role in prescribing these new monoclonal antibodies for Alzheimer's disease? We've got a lot to talk about, including redefining dementia, which we'll talk about, where there's a draft proposal from the NIA and Alzheimer's Association on redefining Alzheimer's disease as a purely biological marker definition. But before we jump into all of that. I think somebody has a song request for Alex. Nate, is it you? No, it's Sharon. Yeah, Sharon won.

Sharon Brangman 1:55

Well yeah, I I would like to hear Doctor My Eyes. I thought it was appropriate for the subject and all of us being docs. So hit it, Alex.

Alex Smith 2:05

Great.

2:08

Doctor my eyes have seen the years and the slow parade of fears without crying now I want to understand. I have done all that I could to see the evil and the good without hiding. You must help me if you can. Doctor Ma And tell me what went wrong was I unwiel. To leave him open for so long.

Eric Widera 2:49

That was wonderful. Sharon, why'd you pick that song?

Sharon Brangman 2:54

Well, we're in geriatrics and most of my patients have had their eyes open for a very long time and have seen the evil and the good. So well

Eric Widera 3:02

said. So let's let's jump right into the topic. We're gonna be talking about amyloid antibodies for Alzheimer's disease, monoclonal antibodies towards the treatment of Alzheimer's disease. You know, the field of geriatrics has been, I would say, somewhat negative on these drugs. I think in large part, you know, it's due to a terrible launch, probably the worst drug launch of all time, which was Aljucanimab, which is now really out of the market. But we have two new drugs. Lacanimab and Dananomab both now published. Both one Lacanomab likely FDA or it is FDA approved now. Likely Dananomab will become FDA approved. I'm wondering if I can I'm gonna start off by asking all three of you geriatricians. Are you gonna be using these drugs?

Eric Widera 3:51

And do you think we as a field should be using them? Uh Jason, you've been uh both a loud uh opponent of agicantomab, but more recently uh somebody who's been pushing more for us to think about the use of lacanimab. What do you think about this?

Jason Karlawish 4:07

Oh, I plan to prescribe lecanomab and denanomab. Well lecanomab I because it's FDA approved, assuming Dananomab is FDA approved, I will be a prescriber. Um and I do think geriatricians need to e as individuals make that decision uh largely based on their comfort with um the diagnostics um and the specifics of the therapeutics. Um if anyone's wondering, oh wait a minute, what about add to Kennbat? My answer to that is Adequantema was just a failure of regulatory science. Um it wasn't about the drug itself, it was about the decision.

Show notes

It's been over two years since one of the worst product launches of all time - Aduhelm (aducanumab). Praised by the FDA, Alzheimer's Association (AA), and Pharma as a "game changer", but derided by others for the drug's lack of clinical efficacy, risk of severe adverse effects, absence of diversity in trial populations, high costs, and an FDA approval process that was in the kindest words "rife with irregularities". Instead of Biogen's expected billions of dollars of revenue from Aduhelm, they brought in only $3 million in revenue for all of 2021 (here is my Twitter summary of this fiasco). The outlook on amyloid antibodies are looking brighter though in 2023. Phase III studies for lecanemab and donanemab have been published showing less worsening of cognition and function receiving these agents versus placebo. This led the FDA to give full approval for lecanemab, which will likely be followed by full approval of donanemab sometime this year. However, as noted in our editorial published with the donanemab trial, the modest benefits of amyloid antibodies would likely not be questioned by patients, clinicians, or payers if amyloid antibodies were low risk, inexpensive, and simple to administer. However, they are none of these. So what is the role of individuals like geriatricians in prescribing amyloid antibodies and caring for individuals who are receiving them? We invited three geriatricians and memory care doctors, Nate Chin, Sharon Brangman, and Jason Karlawish, to talk about this question and many others swirling around on how to safely prescribe these drugs and manage patients on them (like what to do about anticoagulation). Lastly, we also spend a little bit of time talking about the NIA-AA draft statement on redefining Alzhiemers disease. There is a lot to digest with these draft clinical guidelines but the big change from the 2018 guideline is moving Alzheimers to a biological diagnosis (biomarker evidence only) not just for a research framework but now from a clinical one. One outcome would be a very large population of older adults with normal cognition could now be classified as having Alzheimer's disease (maybe about a 1/3 of cognitively normal 75 year olds based on PET). So if you have thoughts on the matter, please give your feedback here to the NIA and AA. https://aaic.alz.org/nia-aa.asp By: Eric Widera
