Reasons for Hope in ALS Research with the Discovery of NU-9

Neuron

In a study funded in part by The ALS Association’s TREAT ALS program, researchers from Northwestern University have identified the first compound (NU-9) that eliminates the ongoing degeneration of diseased upper motor neurons, a key contributor to ALS. While this news is exciting, this study has only tested the compound in mice and in laboratory neurons and is in the very early stages. Researchers must now determine if this particular compound can be further developed for humans and would need to do additional chemistry to optimize the compound. In addition, assessments are needed to determine whether this compound can get into the brain and spinal cord at appreciable levels, engage with its target and if it is safe and tolerable. Although still early in its development, we are encouraged by the addition of another therapeutic intervention in the ALS drug discovery pipeline and are happy that our funding was able to seed this line of research work.  

In a recent Connecting ALS podcast, Dr. Kuldip Dave, vice president of research for The ALS Association, talked about these new findings and the hope they bring to the ALS community and global research collaboration. A portion of that conversation has been edited and condensed below.

ALS research has been making headlines since we turned the calendar into 2021. And one of the more exciting developments is related to a paper published in Clinical and Translational Medicine, describing how researchers at Northwestern reported that they identified a compound that eliminated degeneration of motor neurons that are connected to the development of ALS. What have you heard about this development and what can you tell us about research into the compound known as NU-9?
We're very excited to see these findings published. Let's first talk about the project itself before we talk about NU-9. The ALS association supported Dr. Ozdinler and her team at Northwestern University a few years ago through the funds raised during the Ice Bucket Challenge. And the goal of the project was to find out the protein landscape of healthy and vulnerable, motor neurons in two different stages of the disease. So, what do I mean by that? We know that in ALS we have neurons, which are brain cells that are sick and dying, and we have neurons that are fine and healthy. And we know that those are unhealthy sick neurons, things start to dysfunction. And Dr. Ozdinler wanted to see what proteins are changing in neurons that are sick versus neurons that are fine and healthy.

In other words, can changes in protein landscape lead to neurons being more vulnerable to cell death. And why is this important? Because if we can find those proteins that are specific to unhealthy neurons, then those can serve as markers to tell us something bad is going on, or they can serve to identify new therapeutic targets for us. For example, if we know certain protein is dysfunctional, then we can make drugs against that cookie.

The other reason why Dr. Ozdinler’s work that you mentioned, that was published in Clinical and Translational Medicine, why it is so relevant is that it was focusing on upper motor neurons. So, what are upper motor neurons? These neurons take signals from the brain and transmit them to the spinal cord so that movement can happen. So, they're very, very important in ALS.

And we know that these upper motor neurons get sick, degenerate and die in ALS. So this was the rationale for our funding a few years back for this study, and the results of that funding was that her team found that there were certain proteins and protein function that was changed in two very specific cellular structures: the mitochondria, which is the energy producer of our cells; and this other cellular structure called ER or endoplasmic reticulum. I know that's a big, big word, which is involved in making new proteins and folding them the right way.

So how did they, how did they find this drug? Researchers at Northwestern University screened and tested over 50,000 compounds. And then they did multiple rounds of optimizing the chemistry, and that's how they got this compound, NU-9. Now, remember I told you that they found protein changes in upper motor neurons in two different areas, mitochondria and the ER? They tested this compound, NU-9, in cells and in animals and found that the drug improved the structural integrity of those two structures, the mitochondria and ER. The drug kind of stabilized cell death, and in fact – and this was really significant – reversed some of the pathology, the bad stuff that was going on, essentially making sick neurons healthy again. And in mice, it also improved motor function. So, this is really very, very exciting.

Where are we now in terms of what we know about NU-9? What are the next steps between today and having something that is marketable and available for people with ALS?
Hope is a big thing in ALS. When we see good data, positive results like this, there is certainly going to be a lot of excitement, but there are a couple of things we should keep in mind here in terms of the timeline. This research was conducted on mouse models, and there are a few steps that still need to happen. These are early results. They already have a lot of information collected on the drug: where it acts, whether it enters the brain, how long does it stay in the brain, these are the things we call PK or pharmacokinetics of the drug. It's great that they have this information.

Now they need to make sure that the chemistry of the compound is such that it can be given to humans. They would also need to make sure that the drug is safe and tolerable, and generally that is done in two different species of animals. And once they have that data, they can then submit a package to the FDA to ask to do a clinical trial. And when the FDA looks at the data package and grants them a go ahead, that is when they can start to test the treatment in humans for safety and efficacy.

I was diagnosed with bulbar ALS in 2013, but had symptoms as early as 2006. Then after a couple of years it was determined I have PLS. My symptoms are very slow to progress, but I can barely speak or walk. I want to be part of the NU9 clinical trial ASAP! Thank you.

My brother has now been suffering with ALS for almost 3 years. it is progressing quickly but he is still clinging on to hope of a cure.
This new NU-9 compound sound like a major breakthrough in the fight against ALS.
He is now Completely bed bound and is more than happy to join any NU-9 clinical trials.
These people are suffering beyond any comprehension knowing that there is only one end result without these trials. Someone need to wake up an smell the coffee and allow these sufferers to try the NU-9 compound .
After all they have nothing to loose yet everything to gain.

Diagnosed with als in November 2020 would be more than willing to try NU9 compound .I will sign a waiver or whatever it takes. We need to fast track this through the fda Thx sincerely Bob Demanett

Hi
Do you have an estimated time, before you start experiments in humans?
Is it possible to donate specifically for the development of NU-9?

now a few months later, would there be something to report about NU-9??
hear that people inject themselves with poison to get rid of the misery. for god's sake why can't they make more speed.
just as fast as corona

Would love to be part of this in a trial if or when it happens. There has to be something out there that can help pALS get better and live longer.The only hope we have is to beg for something to make us better. BEG I will.

Hi, I was diagnosed with cerebellum ataxia since 2016.my life turned upside down.
I would love to be your clinical trail. Thank you and good luck on your research.

I have recently been diagnosed with ALS, but began seeing symptoms almost two years ago. My condition was mis-diagnosed a year ago as Multifocal Motor Neuropathy. IVIG treatments seemed to initially show benefit, but my symptoms started getting worse in October, 2021.

I would like to participate in the clinical trial for NU-9. I ask that you contact me when the trial opens for enrollment. I also encourage those constructing the trial to see the drug as something that either cures the disease or it doesn’t, therefore eliminating the need for a control group.

It's frustrating that they've coined the compound "NU-9" to mask what it actually is. No doubt it's something common and readily available, like table salt.

This a bomb shell, or at least it was for me. I have been recently diagnosed with ALS, Lou Gehrig disease. The diagnosis was confirmed by University of Penn, in Philly. The why and how just escapes me. I still am hanging on to hope and prayers. Nu9 might be the answer to my prayers.

They rather save mice than humans. Governments and the people in charge are not proud enough to actually find cures. And when they do, they wait years. Of course unless one of there own gets ALS then the process is cut in days from approval. All terminal diseases should be given any new promising drug without trials. But ok, lets save the mice instead

The only people who kill you is the government. Time to wake up and start going our own way. It is actually a matter of life and death. When your at that point, thats when Governments start running to hide. Because believe me, the system will be brought to its knees like never before!
