| SAN RAFAEL, Calif., /PRNewswire/ -- BioMarin Pharmaceutical Inc.(NASDAQ: BMRN), a company focused on innovative therapies to treat rare diseases, provided highlights to the investment community on its key milestones for 2019 at the 37th Annual J.P. Morgan Healthcare Conference in San Francisco.
“With multiple development and regulatory milestones expected in 2019, BioMarin maintains strong pipeline momentum. We are looking forward to advancing multiple product candidates in parallel through the development process,” said Jean-Jacques Bienaimé, BioMarin Chairman and CEO. “Our focus on the unmet needs in rare genetic diseases and demonstrating meaningful clinical benefits provides the foundation to move rapidly through product development and commercialization.” During the company’s presentation at the conference, Bienaimé provided information on the company’s development program for valoctocogene roxaparvovec gene therapy for severe hemophilia A. BioMarin has completed enrollment of the initial cohort of patients in its Phase 3 program intended to support a BLA submission through the accelerated approval pathway. A decision to submit a BLA through an accelerated approval pathway is tracking for the second half of 2019. If the company submits a BLA using the accelerated approval pathway, it will disclose additional information on the timing of its plans regarding the BLA submission. The complete Phase 3 study is targeting enrollment of 130 patients by mid-year 2019. Valoctocogene roxaparvovec has Orphan Drug designation from the FDA and the European Medicines Agency (EMA). Valoctocogene roxaparvovec has also been accepted for Priority Medicines (PRIME) scheme from the EMA. Additionally, the FDA has granted valoctocogene roxaparvovec Breakthrough Therapy designation. BioMarin also provided an update on its clinical program for vosoritide, an analog of C-type Natriuretic Peptide (CNP), in children with achondroplasia, the most common form of disproportionate short stature in humans. BioMarin expects top line results from the fully enrolled Phase 3 study of vosoritide in children by year end 2019. The Phase 2 study in infants and young children up to age 5 with achondroplasia study enrollment is on track, and in this early part of the study, vosoritide is generally well-tolerated. See “About Vosoritide Phase 3 Study” and “About Vosoritide Phase 2 Infant and Young Children Study” below for more information on the studies. Vosoritide has been granted orphan drug designation in both the U.S. and Europe. In addition, Bienaimé noted during the presentation that the company is anticipating an opinion from the Committee for Medicinal Products for Human Use (CHMP), the scientific committee of the European Medicines Agency (EMA) on Palynziq® (pegvaliase) Injection for the treatment of patients 16 and older with PKU in 1Q 2019. If the CHMP provides a positive opinion in 1Q 2019, then in 2Q 2019, it is possible that the European Commission (EC) could provide marketing authorization in the European Union. In addition, the company provided 2019 global revenue guidance for Palynziq of between $70 and $100 million. Palynziq, a PEGylated recombinant phenylalanine ammonia lyase enzyme approved in the United States in May 2018, is the first approved enzyme substitution therapy to target the underlying cause of phenylketonuria (PKU) by helping the body to break down Phe. PKU is a rare genetic disease that manifests at birth and results in a variety of cumulative toxic effects on the brain. Palynziq is BioMarin’s second approved treatment for this serious condition. In March 2018, the European Medicines Agency accepted BioMarin’s submission of a Marketing Authorization Application for Palynziq. Gene Therapy Manufacturing BioMarin has constructed one of the largest gene therapy manufacturing facilities of its kind, which is located in Novato, California. Good Manufacturing Practices (GMP) production of valoctocogene roxaparvovec has commenced supporting clinical development activities and will support any anticipated commercial demand. This facility is capable of supporting approximately 4,000 doses per year, and the production process was developed in accordance with International Conference on Harmonisation guidance for Pharmaceuticals for Human Use to facilitate worldwide registration with health authorities. Clinical supplies for valoctocogene roxaparvovec for Hemophilia A and BMN 307, a pre-clinical gene therapy for PKU, are produced in this facility. About BioMarin and Disease Information BioMarin is a global biotechnology company that develops and commercializes innovative therapies for patients with serious and life-threatening rare and ultra-rare genetic diseases. The company’s portfolio consists of seven commercialized products and multiple clinical and pre-clinical product candidates. For additional information, please visit www.biomarin.com.

About Hemophilia A Hemophilia A, also called factor VIII (FVIII) deficiency or classic hemophilia, is a genetic disorder caused by missing or defective factor VIII, a clotting protein. Although it can be passed down from parents to children, about 1/3 of cases are caused by a spontaneous mutation, a new mutation that was not inherited. Approximately 1 in 10,000 people predominantly male is born with Hemophilia A. People living with the disease are not able to form blood clots efficiently and are at risk for excessive bleeding from modest injuries, potentially endangering their lives. People with severe hemophilia often bleed spontaneously into their muscles or joints. The standard of care for the 49% of individuals with hemophilia A who are severely affected is a prophylactic regimen of Factor VIII infusions two to three times per week. Even with prophylactic regimens, many people still experience spontaneous bleeding events that result in progressive and debilitating joint damage. Valoctocogene Roxaparvovec Phase 1/2 Study Safety Overall, valoctocogene roxaparvovec has been well-tolerated by patients across all doses. No patients developed inhibitors to Factor VIII and no patients withdrew from the study. The most common AEs across all dose cohorts were alanine aminotransferase (ALT) elevation (11 patients, 73%); arthralgia, aspartate aminotransferase elevation, and headache (7 patients each, 47%); back pain and fatigue (5 patients each, 33%). Two patients reported SAEs during the study. One patient was hospitalized for observation after developing Grade 2 pyrexia with myalgia and headache within 24 hours of receiving valoctocogene roxaparvovec. The event resolved within 48 hours following treatment with paracetamol, an over-the-counter treatment for pain and fever. The event was assessed as related to valoctocogene roxaparvovec. The other AE was assessed as not related to the therapy, attributed to a planned knee surgery to treat hemophilic arthropathy, and Grade 1 in severity. No complications were reported. About Achondroplasia Achondroplasia, the most common form of disproportionate short stature in humans, is characterized by failure of normal conversion of cartilage into bone, which results in disproportionate short stature. This condition is caused by a mutation in the fibroblast growth factor receptor 3 gene (FGFR3), a negative regulator of bone growth. Beyond disproportionate short stature, people with achondroplasia can experience serious health complications, including foramen magnum compression, sleep apnea, bowed legs, mid-face hypoplasia, permanent sway of the lower back, spinal stenosis and recurrent ear infections. Some of these complications can result in invasive surgeries such as spinal cord decompression and straightening of bowed legs. In addition, studies show increased mortality at every age. 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. Vosoritide is being tested in children whose growth plates are still “open,” typically those under 18 years of age. This is approximately 25% of people with achondroplasia. In the U.S., Europe, Latin America and the Middle East, there is currently no licensed medicines for achondroplasia. About Vosoritide Phase 3 Study The global Phase 3 study is a randomized, placebo-controlled study of vosoritide in approximately 110 children with achondroplasia ages 5-14 for 52 weeks. The study will be followed by a subsequent open-label extension. Children in this study will have completed a minimum six-month baseline study to determine their respective baseline growth velocity prior to entering the Phase 3 study. Vosoritide is being tested in children whose growth plates are still open. This is approximately 25% of people with achondroplasia. The primary endpoint of the study is the change in growth velocity from baseline over one year in children treated compared to placebo. The company also plans to augment the growth velocity data with assessments of proportionality and functionality. About Vosoritide Phase 2 Infant and Young Children Study The Phase 2 vosoritide study is a randomized, placebo-controlled study of vosoritide in approximately 70 infants and young children with achondroplasia ages zero to less than 60 months for 52 weeks. The study will be followed by a subsequent open-label extension. Children in this study will have completed a minimum three-month baseline study to determine their respective baseline growth prior to entering the Phase 2 study. The primary objectives of the study are to evaluate safety, tolerability, and the effect of vosoritide on height Z-scores, which is the number of standard deviations in relation to the mean height of age-matched, average stature children. The company also plans to augment the height Z-score data with assessments including proportionality, functionality, quality of life, sleep apnea, and foramen magnum dimension, as well as the advent of major illnesses and surgeries. Vosoritide Safety Vosoritide, administered in over 28,000 injections, was generally well tolerated at all doses. The majority of adverse events (AEs) were mild and no serious adverse events (SAEs) were reported as study drug-related. Across all doses, injection site reactions and hypotension were the most common drug-related AEs. All injection site reaction events were transient. AEs of hypotension were mild, transient and resolved without medical intervention, and the majority were asymptomatic and reported in context of routine blood pressure measurements. No new safety findings were observed at the 30 µg/kg/day dose. About Phenylketonuria PKU, or PAH deficiency, is a genetic disorder affecting approximately 90,000 diagnosed patients in the regions of the world where BioMarin operates and is caused by a deficiency of the enzyme PAH. This enzyme is required for the metabolism of Phe, an essential amino acid found in most protein-containing foods. If the active enzyme is not present in sufficient quantities, Phe accumulates to abnormally high levels in the blood and becomes toxic to the brain, resulting in a variety of complications including severe intellectual disability, seizures, tremors, behavioral problems and psychiatric symptoms. As a result of newborn screening efforts implemented in the 1960s and early 1970s, virtually all individuals with PKU under the age of 40 in countries with newborn screening programs are diagnosed at birth and treatment is implemented soon after. PKU can be managed with a Phe-restricted diet, which is supplemented by low-protein modified foods and Phe-free medical foods; however, the strict diet is difficult for most adult patients to adhere to the extent needed for achieving adequate control of blood Phe levels.

About Palynziq Palynziq substitutes the deficient phenylalanine hydroxylase (PAH) enzyme in PKU with the PEGylated version of the enzyme phenylalanine ammonia lyase to break down Phe. Palynziq is administered using a dosing regimen designed to facilitate tolerability; Palynziq’s safety profile consists primarily of immune-mediated responses, including anaphylaxis, for which robust risk management measures effective in clinical trials are in place. The dosing and administration of Palynziq follows an induction, titration, and maintenance paradigm. Treatment is individualized to the lowest effective and tolerated dosage. Prescribers may consider increasing to a maximum of 40 mg once daily in patients who have not achieved a response with 20 mg once daily for at least 24 weeks. Prescribers are instructed to discontinue treatment in patients who have not responded after 16 weeks of continuous treatment with the maximum dosage of 40 mg once daily. Periodic blood Phe monitoring is recommended, and patients should be counseled on how to adjust their dietary intake, as needed, based on blood Phe concentrations. Indication Palynziq (pegvaliase-pqpz) Injection is a phenylalanine-metabolizing enzyme indicated to reduce blood phenylalanine concentrations in adult patients with PKUwho have uncontrolled blood phenylalanine concentrations greater than 600 µmol/L on existing management.
