Disease modification represents the future of CNS drug development. In this era, molecular markers of disease progression and drug activity will prove to be as necessary as the therapies themselves. At C2N Diagnostics, we are leading ways to provide new insights into the molecular mechanisms of brain diseases, track early progression, and measure the biologic activity of emerging therapies. By measuring the concentration and metabolism of CNS-derived biomolecules using sensitive stable isotope labeling, we provide novel insights into the normal and abnormal workings of the brain. Our ultimate goal? To accelerate the development of new therapies that will reverse or prevent neurodegeneration.
