ROCKVILLE, Md., January 6, 2017 — REGENXBIO Inc. (Nasdaq: RGNX), a leading biotechnology company focused on the development, commercialization and licensing of recombinant adeno-associated virus (AAV) gene therapy based on its proprietary NAV® Technology Platform, today provided a year-end 2016 corporate update.
“In 2016, REGENXBIO saw substantial progress in meeting the development goals for our lead product candidate programs and building our core organization; we expect this to continue in 2017 as we work toward generating a robust clinical pipeline of product candidates that hold the potential to improve treatment in many diseases. This year we anticipate clinical data reporting from programs using our NAV Technology, including our trials of RGX-314 for the treatment of wet age-related macular degeneration, RGX-501 for the treatment of homozygous familial hypercholesterolemia, and trials from our licensees AveXis, Dimension and Audentes,” said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO. “In addition, we expect several new INDs for NAV Technology programs to be filed in 2017, further expanding the clinical pipeline of NAV-based gene therapies that have the potential to benefit patients in need.”
Year-End 2016 Highlights
Recent highlights related to REGENXBIO’s internal lead product candidate programs include:
| • | REGENXBIO filed an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) during the first week of 2017 to support the Phase I clinical trial of RGX-314 for the treatment of wet age-related macular degeneration (wet AMD). IND-enabling studies for RGX-314 and the manufacture of material to support initiation of the Phase I clinical trial were completed in 2016. |
| • | REGENXBIO and trial sponsor the University of Pennsylvania had commenced screening for patients with homozygous familial hypercholesterolemia (HoFH) for inclusion in a Phase I/II clinical trial of RGX-501. REGENXBIO today announced that the sponsor has initiated changes to the protocol intended to broaden the eligible and available patient population. As a result of these changes, which are expected to facilitate enrollment in this trial as well as future trials for RGX-501, the Phase I/II clinical trial is now projected to begin enrolling in the first half of 2017. REGENXBIO plans to provide further updates during the first quarter of 2017. |
| • | IND-enabling studies for RGX-111 for the treatment of Mucopolysaccharidosis Type I (MPS I) are nearing completion, and the manufacture of material to support initiation of a Phase I/II clinical trial has been completed. |
| • | IND-enabling studies for RGX-121 for the treatment of Mucopolysaccharidosis Type II (MPS II) are expected to be completed in the second quarter of 2017. REGENXBIO also initiated the manufacture of material to support the planned Phase I/II clinical trial. |
| • | REGENXBIO invested in internal capabilities, expanded its contract manufacturing network and opened an advanced manufacturing and analytics lab. |
