BioMarin Pharmaceutical Inc. (NASDAQ: BMRN), a global biotechnology company dedicated to transforming lives through genetic discovery, announced today that the European Medicines Agency (EMA) validated its Type II Variation application to extend the indication for VOXZOGO® (vosoritide) for injection to treat children with achondroplasia under the age of 2.
| BioMarin Submits Supplemental New Drug Application to U.S. Food and Drug Administration to Expand Label to Treat Children with Achondroplasia Under the Age of 5 Submissions Based on Favorable Results from Global Randomized Phase 2 Study in Infants and Young Children Demonstrating Increase of Growth Velocity in All Cohorts by Age Potential to Benefit More than 1,000 Eligible Children in U.S. and Europe Action by Health Authorities Expected in 2H 2023 SAN RAFAEL, Calif., Jan. 3, 2023 /PRNewswire/ --BioMarin Pharmaceutical Inc. (NASDAQ: BMRN), a global biotechnology company dedicated to transforming lives through genetic discovery, announced today that the European Medicines Agency (EMA) validated its Type II Variation application to extend the indication for VOXZOGO® (vosoritide) for injection to treat children with achondroplasia under the age of 2. Validation confirms the submission is complete and begins the EMA’s review process. The Company also announced that it submitted a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) to treat children with achondroplasia under the age of 5. Approval of the submissions would mean VOXZOGO could potentially be prescribed as early as birth with more than 1,000 additional children eligible for treatment for achondroplasia, the most common form of disproportionate short stature in humans. The Company anticipates action by health authorities in the second half of 2023.
BioMarin Submits Supplemental Applications for VOXZOGO Indication Extensions for Younger Children; EU Validates The supplemental marketing applications are based on the outcomes from a Phase 2 randomized, double-blind, placebo-controlled clinical trial to evaluate the safety and efficacy of VOXZOGO™ (vosoritide) for injection in infants and children aged 3 months to less than five years old. “We are pleased by results showing an increase in growth velocity across all age cohorts. These data are very encouraging and supportive of expanding the indication to younger children,” said Hank Fuchs, M.D., President, Worldwide Research and Development at BioMarin. “We look forward to further dialogue with health authorities in the U.S. and Europe to review these submissions to expand access to VOXZOGO treatment for this younger age group. Our hope is that children around the world will have the same access as children in Japan where VOXZOGO is approved in all children with achondroplasia, whose growth plates are not closed.” VOXZOGO is the first FDA and EMA approved treatment for children with achondroplasia with open epiphyses (bone growth plates). In patients with achondroplasia, endochondral bone growth, an essential process by which bone tissue is created, is negatively regulated due to a gain of function mutation in fibroblast growth factor receptor 3 gene (FGFR3). Voxzogo, a modified C-type natriuretic peptide (CNP), directly targets the underlying pathophysiology of achondroplasia by down regulating fibroblast growth factor receptor 3 (FGFR3) signaling and consequently promoting endochondral bone formation. VOXZOGO Safety The safety profile was generally consistent with that seen in older subjects in the Phase 3 VOXZOGO 301 study (the current label population in the U.S.). Serious Adverse Events (SAEs) were higher in the placebo group (18%) compared to VOXZOGO -treated children (7%). All SAEs, including a fatal respiratory arrest (reported as a sudden infant death syndrome in a treated infant with pre-existing respiratory morbidity), were deemed by the investigators to be unrelated to treatment. The most common adverse events were mild and self-limiting injection site reactions. See the U.S. Important Safety Information below and full Prescribing Information and the EU (European Union) Summary of Product Characteristics for additional safety information]. Study Description The 52-week phase 2 study enrolled 75 infants and young children with achondroplasia, aged zero to less than five years old (60 months). The study consists of three cohorts by age (24 months to less than 5 years, 6 months to less than 24 months, less than 6 months) and is followed by a subsequent open-label extension trial where all children receive active treatment. Children in this study have completed a minimum three- or six-month baseline study to determine their respective baseline growth prior to entering the Phase 2 study. The objectives of the study are to evaluate safety, tolerability, and the effect of VOXZOGO on growth. The study also evaluated proportionality, functionality, quality of life, sleep apnea, and foramen magnum dimension, as well as the advent of major illnesses and surgeries which frequently occur in children with achondroplasia. About VOXZOGO™ (vosoritide) for Injection In patients with achondroplasia, endochondral bone growth, an essential process by which bone tissue is created, is negatively regulated due to a gain of function mutation in fibroblast growth factor receptor 3 gene (FGFR3). VOXZOGO, a C-type natriuretic peptide (CNP) analog, represents a new class of therapy, which acts as a positive regulator of the signaling pathway downstream of FGFR3 to promote endochondral bone growth. VOXZOGO continues to be studied in a broad clinical development program in achondroplasia, and safety and efficacy are being further evaluated across different ages and over time. To date, 250 children with achondroplasia from eight countries have been enrolled in seven BioMarin clinical studies evaluating the safety and efficacy of VOXZOGO. VOXZOGO is approved in the U.S. and indicated to increase linear growth in pediatric patients with achondroplasia who are 5 years of age and older with open epiphyses. This indication is approved under accelerated approval based on an improvement in annualized growth velocity. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). To fulfill this post-marketing requirement, BioMarin intends to use the ongoing open-label extension studies compared to available natural history. VOXZOGO is also approved in the E.U., Brazil, and Australia in children with achondroplasia who are 2 years of age and older with open growth plates. It is also approved in Japan in children with achondroplasia who are 0 and older with open growth plates. About Achondroplasia Achondroplasia, the most common form of skeletal dysplasia leading to disproportionate short stature in humans, is characterized by slowing of endochondral ossification, which results in disproportionate short stature and disordered architecture in the long bones, spine, face, and base of the skull. This condition is caused by a change in the fibroblast growth factor receptor 3 gene (FGFR3), a negative regulator of bone growth. More than 80% of children with achondroplasia have parents of average stature and have the condition as the result of a spontaneous gene mutation. The worldwide incidence rate of achondroplasia is about one in 25,000 live births. VOXZOGO is being tested in children whose growth plates are still “open”, typically those under 18 years of age. Approximately 25% of people with achondroplasia fall into this category. VOXZOGO U.S. Important Safety Information What is VOXZOGO used for?
