Biotech firm Denali announced the dosing of the first person in their Phase Ib clinical study of their experimental treatment for Parkinson’s called DNL201.
DNL201 is an inhibitor of a Parkinson’s-associated protein called Leucine-rich repeat kinase 2 (LRRK2).
In Parkinson’s, there is evidence that LRRK2 is over activate, and by inhibiting LRRK2 Denali is hoping to slow the progression of Parkinson’s.
In today’s post, we will discuss what LRRK2 is, what evidence exists for DNL201, and what the new clinical trial will involve.
Founded in 2013, by a group of former Genentech executives, San Francisco-based Denali Therapeutics is a biotech company which is focused on developing novel therapies for people suffering from neurodegenerative diseases. Although they have product development programs for other condition (such as Amyotrophic Lateral Sclerosis and Alzheimer’s disease), Parkinson’s is their primary interest.
And their target for therapeutic effect?
The Parkinson’s-associated protein called Leucine-rich repeat kinase 2 (or LRRK2).
What is LRRK2?

Millions of dollars in research funding for Parkinson’s has been poured into the biology and function of just one hyperactive protein. It is called Leucine-rich repeat kinase 2 (or LRRK2). Genetic mutations in the gene that gives rise to this abnormal version of the protein can leave carriers with a higher risk of developing Parkinson’s.
All of that research funding has resulted in an incredible leap forward in our understanding of LRRK2, which has further led to clinical trials focused solely on LRRK2. Mutations in the LRRK2 gene occur in only 1-2% of the Parkinson’s population, however, which has led to some complaints that too much research is being focused on only a small fraction of the people affected by PD.
New research published this week could silence those complaints.
In today’s post we will discuss a new report suggesting that independent of any genetic mutations, LRRK2 may actually play a role in idiopathic (or spontaneous) forms of Parkinson’s, which means that the treatments being developed for LRRK2 could be beneficial for a wider section of the PD community.
This is Sergey Brin.
He’s a dude.
You may have hear of him – he was one of the founders of a small company called “Google”.
Having changed the way the world searches the internet, he is now turning his attention to other projects.
One of those other projects is close to our hearts: Parkinson’s.
Why is he interested in Parkinson’s?

This week Denali Therapeutics released the results of a phase I clinical trial of their primary product, called DNL-201.
DNL-201 is a LRRK2 inhibitor that the company is attempting to take to the clinic for Parkinson’s disease.
In today’s post we will look at what LRRK2 is, how an inhibitor might help in Parkinson’s, and what the results of the trial actually mean.

Denali (Koyukon for “the high one”; also known as Mount McKinley) in Alaska is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) above sea level. The first verified ascent to Denali’s summit occurred on June 7, 1913, by four climbers Hudson Stuck, Harry Karstens, Walter Harper, and Robert Tatum.

Robert Tatum later commented, “The view from the top of Mount McKinley is like looking out the windows of Heaven!”
More recently another adventurous group associated with ‘Denali’ have been trying to scale lofty heights, but of a completely different sort from the mountaineering kind.
