The study involves a replication-incompetent adeno-associated virus, AAV9, lacking all AAV viral genes and encoding for the human Progranulin (GRN) gene
Non-replicating recombinant vector derived from adeno-associated virus AAV6 serotype, containing a codon-optimised version of the human Factor VIII gene
Non-replicating recombinant vector derived from adeno-associated virus AAV9, lacking all AAV viral genes and containing a miniaturized version of the human dystrophin gene
