BioMarin Announces Agreement with German Health Insurance Fund on Reimbursement Amount for ROCTAVIAN® (valoctocogene roxaparvovec-rvox) for Severe Hemophilia A in Germany

ROCTAVIAN is First Gene Therapy for Hemophilia to Receive Approved Federal Price in Germany

SAN RAFAEL, Calif., Nov. 28, 2023 /PRNewswire/ -- BioMarin Pharmaceutical Inc. (Nasdaq: BMRN), a global biotechnology company dedicated to transforming lives through genetic discovery, today announced an agreement with the German National Association of Statutory Health Insurance Funds (GKV-SV) on the reimbursement amount for ROCTAVIAN^® (valoctocogene roxaparvovec-rvox) for people with severe hemophilia A. This is the first gene therapy for hemophilia to receive an agreed federal price in Germany. ROCTAVIAN brings value to individuals and the healthcare system in Germany, as a one-time, single-dose therapy delivered as an intravenous infusion over 3-4 hours at a gross price of €28,933.53 per vial. This vial price equates to approximately $900,000 per patient in net revenue to BioMarin at the current exchange rate, accounting for average patient weight and number of vials required for the one-time treatment, estimated reductions for customary rebates and discounts.

"We are pleased to have reached an agreement on the reimbursement amount for ROCTAVIAN with the GKV-SV, which is responsible for health insurance that covers approximately 90% of the German population," said Jeff Ajer, executive vice president and chief commercial officer at BioMarin. "This important progress will facilitate access to ROCTAVIAN for eligible individuals among the roughly 2,000 adults with severe hemophilia A in Germany and marks a key step forward for the hemophilia community."

BioMarin and GKV-SV have agreed on an outcome-based prospective cohort model for ROCTAVIAN. This will allow future reimbursement to be increased or decreased, based on real-world data collected from the German Haemophilia Registry of patients treated with ROCTAVIAN. This agreement, with a minimum term of 3 years, ensures the supply and reimbursement for eligible patients in Germany with ROCTAVIAN by the GKV-SV.

Two patients in Germany have now received ROCTAVIAN commercially, and 60 people are eligible for next steps based on companion diagnostic testing results for adeno-associated virus serotype 5 (AAV5) antibodies.

Additionally, final price negotiations with the Italian Medicines Agency are underway and expected to be formalized by year-end 2023.

Significant Progress with U.S. Payers

BioMarin continues to work with private and public payers in the U.S. to enable access, with the goal of ensuring that every eligible adult interested in ROCTAVIAN is able to receive treatment.

Numerous coverage policies that now include ROCTAVIAN have been published by leading U.S. payers. While medical exception processes provide a pathway to coverage, these policies representing millions of lives will help increase access to treatment.

The company continues to partner with hemophilia treatment centers (HTCs) across the country to educate them on how to administer ROCTAVIAN, and many HTCs have readiness plans before the end of this year.

It is estimated that there are approximately 6,500 adults living with severe hemophilia A in the U.S. BioMarin expects approximately 2,500 of those adults to be eligible to receive ROCTAVIAN at this time.

About Hemophilia A

Hemophilia A, also called factor VIII (FVIII) deficiency or classic hemophilia, is an X-linked genetic disorder caused by missing or defective FVIII, a clotting protein. Although it is passed down from parents to children, about one-third of cases are caused by a spontaneous mutation, a new mutation that was not inherited. Approximately 1 in 10,000 people have hemophilia A.

About ROCTAVIAN

ROCTAVIAN is an adeno-associated virus vector-based gene therapy used for the treatment of adults with severe hemophilia A who do not have antibodies to adeno-associated virus serotype 5 (AAV5), which is determined by a blood test. The one-time infusion works by delivering a functional gene that is designed to enable the body to produce FVIII on its own, reducing the need for ongoing prophylaxis.

The European Commission (EC) granted conditional marketing authorization to ROCTAVIAN on August 24, 2022. The U.S. Food and Drug Administration (FDA) approved ROCTAVIAN on June 29, 2023.

U.S. Important Safety Information

Contraindications: Patients with active infections, either acute (such as acute respiratory infections or acute hepatitis) or uncontrolled chronic (such as chronic active hepatitis B). Patients with known significant hepatic fibrosis (stage 3 or 4 on the Batts-Ludwig scale or equivalent), or cirrhosis, and patients with known hypersensitivity to mannitol.

Infusion-related reactions including hypersensitivity reactions and anaphylaxis, have occurred. Monitor during and for at least 3 hours after ROCTAVIAN administration. Administer ROCTAVIAN in a setting where personnel and equipment are immediately available to treat infusion-related reactions. Discontinue infusion for anaphylaxis.

Hepatotoxicity: The safety and effectiveness of ROCTAVIAN in patients with hepatic impairment has not been established. Perform liver health assessments prior to administration. The majority of patients treated with ROCTAVIAN experienced ALT elevations and required corticosteroids for ALT elevation. Assess patient's ability to receive corticosteroids and/or other immunosuppressive therapy that may be required for an extended period. Live vaccines should not be administered to patients while on immunosuppressive therapy.

Monitor ALT weekly for at least 26 weeks and as clinically indicated, during corticosteroid therapy and institute corticosteroid treatment in response to ALT elevations as required. Continue to monitor ALT until it returns to baseline. Monitor factor VIII activity levels since ALT elevation may be accompanied by a decrease in factor VIII activity. One case of autoimmune hepatitis was reported during third year follow-up in a patient with history of hepatitis C and steatohepatitis.

It is recommended that patients abstain from consuming alcohol for at least 1 year after administration and thereafter limit alcohol use. Concomitant medications may cause hepatotoxicity, decrease factor VIII activity, or change plasma corticosteroid levels which may impact liver enzyme elevation and/or factor VIII activity or decrease the efficacy of the corticosteroid regimen or increase their side effects. Closely monitor concomitant medication use including herbal products and nutritional supplements and consider alternative medications in case of potential drug interactions.

Thromboembolic events: Factor VIII activity above ULN has been reported following ROCTAVIAN infusion. Thromboembolic events may occur in the setting of elevated factor VIII activity above ULN. Evaluate patients for risk of thrombosis including general cardiovascular risk factors before and after administration of ROCTAVIAN. Advise patients on their individual risk of thrombosis in relation to their factor VIII activity levels above ULN and consider prophylactic anticoagulation. Advise patients to seek immediate medical attention for signs or symptoms indicative of a thrombotic event.

Factor VIII inhibitors and Monitoring for inhibitors: The safety and effectiveness of ROCTAVIAN in patients with prior or active factor VIII inhibitors have not been established. Patients with active factor VIII inhibitors should not take ROCTAVIAN. Following administration, monitor patients for factor VIII inhibitors (neutralizing antibodies to factor VIII). Test for factor VIII inhibitors especially if bleeding is not controlled, or plasma factor VIII activity levels decrease.

Monitor Factor VIII using the same schedule for ALT monitoring. It may take several weeks after ROCTAVIAN infusion before ROCTAVIAN-derived factor VIII activity rises to a level sufficient for prevention of spontaneous bleeding episodes. Exogenous factor VIII or other hemostatic products may also be required in case of surgery, invasive procedures, trauma, or bleeds. Consider more frequent monitoring in patients with factor VIII activity levels ≤ 5 IU/dL and evidence of bleeding, taking into account the stability of factor VIII levels since the previous measurement.

Factor VIII activity produced by ROCTAVIAN in human plasma is higher if measured with one-stage clotting assays compared to chromogenic substrate assays. When switching from hemostatic products prior to ROCTAVIAN treatment, physicians should refer to the relevant prescribing information to avoid the potential for factor VIII activity assay interference during the transition period.

Malignancy: The integration of liver-targeting AAV vector DNA into the genome may carry the theoretical risk of hepatocellular carcinoma development. ROCTAVIAN can also insert into the DNA of other human body cells. Monitor patients with risk factors for hepatocellular carcinoma (e.g., hepatitis B or C, non-alcoholic fatty liver disease, chronic alcohol consumption, non-alcoholic steatohepatitis, advanced age) with regular liver ultrasound (e.g., annually) and alpha-fetoprotein testing for 5 years following ROCTAVIAN administration. In the event that any malignancy occurs after treatment with ROCTAVIAN, contact BioMarin Pharmaceutical Inc. at 1-866-906-6100.

Most Common Adverse Reactions: Most common adverse reactions (incidence ≥ 5%) were nausea, fatigue, headache, infusion-related reactions, vomiting, and abdominal pain. Most common laboratory abnormalities (incidence ≥ 10%) were ALT, AST, LDH, CPK, factor VIII activity levels, GGT and bilirubin > ULN. Patients also experienced adverse reactions from corticosteroid use.

Isotretinoin, Efavirenz, and HIV Positive Patients: Isotretinoin is not recommended in patients who are benefiting from ROCTAVIAN. Efavirenz is not recommended in patients treated with ROCTAVIAN. Clinical studies of ROCTAVIAN did not include sufficient numbers of patients with HIV to determine whether the efficacy and safety differs compared to patients without HIV infection.

Females and Males of Reproductive Potential: ROCTAVIAN is not intended for administration in women. There are no data on the use of ROCTAVIAN in pregnant women or regarding lactation. For 6 months after administration of ROCTAVIAN, men of reproductive potential and their female partners must prevent or postpone pregnancy using an effective form of contraception, and men must not donate semen.

You may report side effects to the FDA at (800) FDA-1088 or www.fda.gov/medwatch. You may also report side effects to BioMarin at 1-866-906-6100.
