Clinical Operational Scientist

With Experience in Quality Management


Treeway B.V. is a Clinical-Stage Dutch Biotech Company developing therapy for ALS and other neurodegenerative diseases. It was founded in 2012 by two ALS patients. Treeway aims to develop drugs that first delay disease progression, followed by therapies that halt or control the disease and finally leading to a breakthrough therapy to cure ALS.

As neurodegenerative diseases share common disease mechanisms, Treeway is now preparing a proof-of-concept clinical phase 2A trial in Alzheimer’s Disease with its lead product. In this phase 2A trial, the effect of Treeway’s product will be compared to placebo in patients diagnosed with Alzheimer’s Disease. In addition, several biomarkers will be tested to evaluate whether a composite endpoint of biomarkers and by introduction of a newly developed cognitive test may lead to a new clinical endpoints and/or new diagnostic tool for improving clinical trials. This is done in collaboration with the Alzheimer Center Amsterdam (ACA) in The Netherlands. The project is (co-) funded by the Alzheimer-Drug Discovery Foundation (ADDF) in the US.


We are looking for a clinical operational scientist, who has experience in clinical trials, quality management and is capable of overseeing the execution of the phase 2A trial with our different collaboration partners. You will be responsible for e.g.

– Coordinating of clinical project management activities and provide operational support
