Billion dollar bets: Denali+Biogen

 

# # # #

This week the biotech firm Denali Therapeutics made two major announcements regarding the development of their LRRK2 inhibitor program for Parkinson’s.

First, the company revealed that they have signed an agreement with the pharmaceutical company Biogen to co-develop and co-commercialise small molecule inhibitors of LRRK2 for Parkinson’s.

Second, Denali also announced that they have a green light from the US FDA to start the next phase of clinical testing of their LRRK2 inhibitor DNL151.

In today’s post, we will discuss what is meant by LRRK2 inhibitor, what the details of the announcements are, and what all of this means for the Parkinson’s community.

Peaking at 20,310 feet (or 6,190 m) above sea level, Denali (Koyukon for “the high one”; also known as Mount McKinley) is the highest mountain in North America. The first verified ascent of this Alaskan mountain occurred on June 7, 1913, when four climbers (Hudson Stuck, Harry Karstens, Walter Harper, and Robert Tatum) conquered it.

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 to the mountaineering kind.

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 definitely their primary indication of interest.

And this week, the company made two major announcements with regards to their Parkinson’s research program.

The first announcement was that Denali have signed an agreement with the pharmaceutical company Biogen to co-develop and co-commercialise small molecule inhibitors of LRRK2 for Parkinson’s (Click here to read the press release).

New LRRK2 results: Game changer?

 

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?
