The professor of genetics at Federal University of Rio Grande do Sul discussed how RGX-121 has the potential to change the treatment landscape of MPSII.
“Patients with the severe form of MPS have progressive cognitive decline. Along the first few years of life, they start to slow down in the neurological development. They do not progress. And at the end, they start to some regress in this development. This is something that occurs in about 75% of patients with MPS that have this severe form. So, there is a need for the majority of patients with MPS to have a therapy to address the central nervous system deterioration.”
The gene therapy RGX-121 (REGENXBIO) was well-tolerated with promising efficacy in treating mucopolysaccharidosis type 2 (MPS II; Hunter syndrome), according to updated data from the phase 1/2/3 CAMPSIITE trial (NCT03566043).
These data were presented at the Society for the Study of Inborn Errors of Metabolism (SSIEM) 2022 Annual Symposium, in Freiburg, Germany, taking place August 30 – September 2, 2022, by Roberto Giugliani, MD, PhD, professor, genetics, Federal University of Rio Grande do Sul and chief, medical genetics service,Clinic Hospital of Porto Alegre, Rio Grande do Sul, Brazil.
CGTLive spoke with Giugliani to learn more about the potential advantages of RGX-121 gene therapy in MPSII. He discussed unmet needs in this patient population.
