ACTRIMS 2021 | Can gold-based nanotechnology meet the need for neuro-reparative therapies in MS?

Therapies targeting neurodegeneration and repair in multiple sclerosis (MS) are an unmet need. Robert Glanzman, MD, FAAN, Clene Nanomedicine Inc, Salt Lake City, UT, discusses nanocatalysts, a new class of drugs that use gold-based nanotechnology to repair and reverse neuronal damage. Pure, nano-sized crystals of therapeutic metals have been manufactured that are able to remain stable in an aqueous solution. CNM-Au8, an aqueous suspension of pure gold nanocrystals, is the most advanced nanocatalyst currently under investigation in clinical trials with promising findings to date. It is hoped that through its ability to enhance processes fundamental to neuronal survival, repair, and function, it has the potential to address the unmet need for neuro-reparative therapies in MS. This interview took place during the ACTRIMS Forum 2021.

So it’s a brand new breakthrough in a therapeutic modality. And the real breakthrough is in being able to manufacture clean surfaced, pure, nano-sized crystals of therapeutic metals, which remain stable in aqueous suspension without the addition of any other excipients. So it’s using plasma physics and a lot of electricity and water, highly purified water, and highly pure wires of transition metals...

So it’s a brand new breakthrough in a therapeutic modality. And the real breakthrough is in being able to manufacture clean surfaced, pure, nano-sized crystals of therapeutic metals, which remain stable in aqueous suspension without the addition of any other excipients. So it’s using plasma physics and a lot of electricity and water, highly purified water, and highly pure wires of transition metals. And our first candidate is CNM-Au8, which is a aqueous suspension of pure gold nanocrystals. So when we say nano, these crystals are on the order of 10 to 16 nanometers in size, which means that they can easily enter cells. They can enter mitochondria, they can actually enter ribosomes. So they’re quite small and they’re pure. So they self-aggregate actually, atom by atom into preferred crystalline shapes, and they self-aggregate in highly purified water and they remain stable in highly purified water without the addition of any other excipients. And that really is the breakthrough. It’s never been possible before.

Again, it’s using plasma physics and what that allows for, these crystals allow for, direct interactions, electronic reactions into biological systems. They can directly receive thousands of electrons per second, or directly donate thousands of electrons per second. So this has really never been possible before. It’s a brand new therapeutic category and we’re very excited to be a part of it. I’m very excited to be a part of it.
