BioMarin Provides Updates on Progress in Gene Therapy Programs
BioMarin Pharmaceutical (NASDAQ: BMRN) provided updates on its gene therapy programs on February 17, 2022. The FDA has requested additional data to lift the clinical hold on the BMN 307 Phase 1/2 study for phenylketonuria, which may take several quarters to assess. Meanwhile, enrollment is complete for the Phase 3 study of valoctocogene roxaparvovec for hemophilia A, with results expected in 1H 2023. The company continues to advance multiple trials, including for BMN 331, which has received Orphan Disease Designation.
- FDA has granted Orphan Disease Designation to BMN 331.
- Enrollment completed for the Phase 3 Study 270-303 for valoctocogene roxaparvovec.

SAN RAFAEL, Calif., Feb. 17, 2022 /PRNewswire/ -- BioMarin Pharmaceutical Inc. (NASDAQ: BMRN) announced updates on its investigational gene therapy programs in clinical development. In February 2022, the Company received additional requests from the Food and Drug Administration (FDA) for information needed to resolve the clinical hold of the PHEARLESS Phase 1/2 study of BMN 307 issued in September 2021. BMN 307 is an AAV5-human phenylalanine hydroxylase (hPAH) gene therapy being studied in adults with phenylketonuria (PKU). The FDA has requested data from additional non-clinical studies to assess the theoretical oncogenic risk to human study participants, which is expected to take several quarters. The company will communicate next steps for the program when available.
"As leaders in the development of gene therapies, a novel treatment modality, it is our responsibility to answer new questions that arise for the benefit of patients, physicians, regulatory bodies, and for the field in general. Patient safety is our utmost priority," said Hank Fuchs, M.D., President, Worldwide Research and Development at BioMarin. "With new technologies in healthcare, we anticipate that both health authorities and developers will seek to characterize and evaluate potential safety-related signals to enable a more comprehensive assessment of these potential risks to patients. We remain grateful to all of the participants and investigators in our gene therapy studies, as well as for the support from patient advocacy groups."
The Company also announced that enrollment has completed in the ongoing Phase 3 Study 270-303 to evaluate the safety and effectiveness of valoctocogene roxaparvovec, an AAV5 gene therapy, in combination with prophylactic corticosteroids in people with severe hemophilia A. Results from the 52-week analysis from this study are expected in 1H 2023.
BioMarin has multiple clinical studies underway in its comprehensive gene therapy program for the treatment of hemophilia A that remain ongoing and/or continue to enroll participants, including the global Phase 3 study GENEr8-1 and the ongoing Phase 1/2 dose escalation study. In addition, the Company is running a Phase 1/2 Study with the 6e13kg/vg dose of valoctocogene roxaparvovec in approximately 10 participants with pre-existing AAV5 antibodies, as well as another Phase 1/2 Study with the 6e13 vg/kg dose of valoctocogene roxaparvovec in people with hemophilia A with active or prior FVIII inhibitors. Finally, the Company announced that its Phase1/2 HAERMONY study to evaluate BMN 331, an investigational AAV5-mediated gene therapy for people living with hereditary angioedema (HAE) is open for enrollment. In addition, the FDA granted Orphan Disease Designation status to BMN 331.
