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?
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.
