Arms and Interventions

Arm Intervention/treatment
Experimental: 4D-310 Dose Level 1 - AAV Neutralizing Antibody (NAb) Group A
Single IV administration of 4D-310 Dose Level 1 - AAV NAb Titer Group A patients
 Biological: 4D-310
4D-310 is a novel adeno-associated virus (AAV) gene therapy comprised of two active components: the capsid (4D-C102) and the transgene cassette, which encodes a codon-optimized full length human GLA transgene driven by the CAG promoter. 4D-310 has been engineered so that it cannot replicate (replication incompetent).
Experimental: 4D-310 Dose Level 1 - AAV NAb Titer Group B
Single IV administration of 4D-310 Dose Level 1 - AAV NAb titer Group B patients
 Biological: 4D-310
4D-310 is a novel adeno-associated virus (AAV) gene therapy comprised of two active components: the capsid (4D-C102) and the transgene cassette, which encodes a codon-optimized full length human GLA transgene driven by the CAG promoter. 4D-310 has been engineered so that it cannot replicate (replication incompetent).
Experimental: 4D-310 Dose Level 2 - AAV NAb Titer Group A
Single IV administration of 4D-310 Dose Level 2 - AAV NAb titer Group A patients
 Biological: 4D-310
4D-310 is a novel adeno-associated virus (AAV) gene therapy comprised of two active components: the capsid (4D-C102) and the transgene cassette, which encodes a codon-optimized full length human GLA transgene driven by the CAG promoter. 4D-310 has been engineered so that it cannot replicate (replication incompetent).
Experimental: 4D-310 Dose Level 2 - AAV NAb Titer Group B
Single IV administration of 4D-310 at Dose Level 2 in AAV NAb titer Group B patients
 Biological: 4D-310
4D-310 is a novel adeno-associated virus (AAV) gene therapy comprised of two active components: the capsid (4D-C102) and the transgene cassette, which encodes a codon-optimized full length human GLA transgene driven by the CAG promoter. 4D-310 has been engineered so that it cannot replicate (replication incompetent).
Experimental: 4D-310 Dose Expansion
Dose expansion cohort of single IV administration of 4D-310 at the selected dose and selected AAV Nab titer group(s) patients
 Biological: 4D-310
4D-310 is a novel adeno-associated virus (AAV) gene therapy comprised of two active components: the capsid (4D-C102) and the transgene cassette, which encodes a codon-optimized full length human GLA transgene driven by the CAG promoter. 4D-310 has been engineered so that it cannot replicate (replication incompetent).
