UX111 (formerly ABO-102) is an investigational novel gene therapy under evaluation in the ongoing pivotal Transpher A trial in patients with Sanfilippo syndrome type A (MPS IIIA).
DTX401 is an investigational adeno-associated virus serotype 8 (AAV8) gene therapy designed to deliver stable expression and activity of glucose-6-phosphatase-alpha (G6Pase-α) using a single intravenous infusion.
DTX301 is an investigational AAV8 gene therapy designed to deliver stable expression and activity of the OTC gene using a single intravenous infusion.
UX701 is an investigational AAV9 gene therapy designed to deliver a modified form of the ATP7B gene, which is otherwise too large to package in an AAV vector.
UX055 is an investigational gene therapy in preclinical development for CDD that aims to deliver a functional copy of the human CDKL5 gene to the brain using an AAV9.

GTX-102 is an investigational antisense oligonucleotide (ASO) therapy designed to inhibit expression of UBE3A-ATS in order to prevent silencing of the paternally inherited allele of the UBE3A gene and reactivate expression of the deficient protein.
