The year 2015 was remarkable for ProQR. We have started enrolling two clinical studies in cystic fibrosis patients and brought a second molecule forward for Leber’s congenital amaurosis. We grew our company to 125 talented and dedicated employees, expanded our headquarters in Leiden, NL and opened an office in Palo Alto, CA.
