THERAPEUTIC PROGRAMS

Advancing the development of potentially
life-changing treatments

We are developing gene therapy product candidates in the retinal, metabolic and neurodegenerative therapeutic areas.

Our gene therapy product candidates all utilize AAV viral vectors from our proprietary gene delivery platform, which we call our NAV Technology Platform. In addition to our internal product candidate programs, we also selectively license our NAV Vectors to other leading biotechnology companies.
