Implementing the impossible

No one wants to grow old, but it is inevitable -- the side effects of it shouldn’t be. Our bodies change, fall apart and become more susceptible to disease.

Galyan Bio is on a mission to change that.

That affects every one of us or someone we know and love 

Neurodegenerative diseases are horrible, difficult to combat and leave patients with little recourse. It is estimated that more than 6 million Americans suffer from Alzheimer’s. By 2050, this number is projected to rise to nearly 13 million. In 2021, Alzheimer’s and other dementias will cost the nation $355 billion. By 2050, these costs could rise as high as $1.1 trillion.

We need solutions, and we need them fast.

Part of the challenge is that, as we age, our ability to break down and remove misfolded proteins gradually diminishes. Think of misfolded proteins as garbage in cells -- they disrupt their functions and finally cause them to die. Now think about what happens when garbage isn't removed from any other area of life, and you'll begin to see how problematic this becomes.

What we really need is a way to help cells remove these proteins, which would not only slow down aging but also improve motor functions and reduce cancer risk.

This, in turn, could subsequently help treat neurodegenerative diseases like Alzheimer’s. As we have demonstrated that our compounds reduce pathological tau and at the same time also tackle amyloid ß.

Proof of Concept
Galyan Bio is developing the real deal. We are so confident in our compounds that we have proudly demonstrated in vivo proof of concept data showing dramatic improvement of median life expectancy of C. elegans and improved motor function in aged animals.

Pharmaceutical Support
We are currently in discussions with a pharmaceutical company for licensing our Huntington disease compounds, with the goal of fighting this horrific and deadly disease.

We filed two matter of composition patents in 2020 and a mode of action patent in 2021.

We are collaborating with Thermally Targeted Therapeutics, Inc., a spin-out of the University of Mississippi. We also have an ongoing collaboration with Bicoll GmbH.

We want to change the future of aging and reduce neurodegenerative diseases

Galyan Bio is on a mission to overcome these problems.

We started in 2015 and worked hard to demonstrate our potential by screening compounds in silico for a Huntington disease target. We were awarded a research grant from the European Union in 2018; we then demonstrated that, in the R6/2 Huntington disease model, our predecessor lead compound (GLYN122) could improve significantly motor symptoms.

We later relocated to the United States and founded Galyan Bio to continue our mission and our research. We have since optimized our compounds and, in 2021, we have demonstrated that GLYN345 improves median survival in the animal model of aging.

We achieve this success with unique small molecules that remove harmful proteins without affecting naturally occurring proteins in cells, which are important for their normal functioning and thus survival of these cells. The compounds bind to misfolded proteins and trigger their degradation by the cells' own protein garbage removal systems, mainly autophagy.

Survive Longer, Live Better
GLYN345 (our lead compound) improves median survival in vivo and the motility of aged animals. As a result, the lead compound has a healthy aging effect.

Improve Quality of Life
Brain aging is one of the greatest challenges we face. We can work out, eat healthy and do all the right things... but if the brain continues to age/fall apart, the rest of the body will do the same.

Thus, we are particularly proud of the way in which our compound overcomes the blood brain barrier and protects also the brain from aging. It is, by far, one of the most important properties of the compound.

Prevent Cancer Like Never Before
Looking ahead, Galyan Bio is proud to have a further optimized compound (GLYN441) of the same series that demonstrated a cancer-killing effect in two different glioblastoma (brain cancer) cell lines. As a result, we are excited to offer a treatment that protects the body and brain from aging while reducing the risk of developing cancer with aging.
