ALS Biotech Company Treeway Announces Promising Phase I Trial Results For Drug TW001

Treeway, a biotech company in the Netherlands with a mission to develop a cure for ALS, recently announced promising results of its phase I trial of its lead drug, TW001. TW001 is an oral formulation of edaravone. Radicava®, the most recently FDA approved drug to treat ALS, is an intravenous version of edaravone. The study showed that TW001 was well tolerated and stable, while improving bioavailability compared to Radicava.

“An oral formulation of Radicava will be pivotal in providing a more convenient means to take the medication in comparison to keeping to a drug infusion schedule,” stated Dr. Lucie Bruijn, chief scientist of The ALS Association.

Based on the promising phase 1 trial results, Treeway is preparing for an upcoming phase III study that will test a larger population of people living with ALS to understand both safety and whether the drug impacts disease progression. The company’s goal is to move as quickly as possible to bring TW001 to the ALS community.

“In collaboration with ALS patients and investigators, we have accomplished this important milestone,” said Inez de Greef, CEO of Treeway. “We are grateful to The ALS Association for their continuous support on our drug development and discovery programs.”

Bernard Muller, Co-Founder, Treeway

Treeway was founded in 2012 by two entrepreneurs who are living with ALS, Bernard Muller and Robbert Jan Stuit. They also founded The ALS Association-funded Project MinE, whose aim is to sequence and analyze the DNA of 22,500 people to discover novel ALS genes.

“We are hopeful for the future of TW001 and will keep the ALS community up-to-date with any additional information,” Bruijn added

  1. Great news! I hope the company succeeds in bringing this new agent to fruition.
    I’m on the infusion and I had to get a port. The infusion keeps me from traveling since I began the regimen.
    I’m grateful for Radicava it’s helped me, but an oral form would be much more convenient.


  2. I have recently been diagnosed with ALS and i am always looking forward to progress on treatments for ALS. So, I would appreciate you keeping my doctor( Dr. Lada) at Barrow Neurological Center in Phoenix,AZ. posted on your progress.


  3. Because my insurance is changing to Medicare, in a short couple of weeks I’ll be forced to go to an IV Clinic as opposed to being able to the medication here in my home. Are there any possibilities that I could received this medication before that happens? Any possibility would be like a dream come true
