Researching Cyclodextrin


Drs. Davidson and Walkley coordinate with SOAR (Support Of Accelerated Research), a collaboration of multiple labs dedicated to developing NPC treatments.


One of Drs. Davidson and Walkley's main focuses is developing a cyclodextrin treatment that doesn't cause hearing loss.

Further Investigation

Drs. Davidson and Walkley have been working hard to refine their understanding of cyclodextrin in order to make it even more effective for NPC treatment.
