What You Don’t Know About the ACA “n Louisiana, Medicaid expansion I could have saved about 500 deaths a year. Opting out is not only a fiscal cost but also a public health issue.” —MARC J. KAHN, MD, MBA ELOCTATE™ [Antihemophilic Factor (Recombinant), Fc Fusion Protein] Lyophilized Powder for Solution For Intravenous Injection. Table 3: Adverse Reactions Reported for ELOCTATE (N=164) MedDRA System Organ Class MedDRA Preferred Term Brief Summary of Full Prescribing Information. Vascular disorders 1 INDICATIONS AND USAGE ELOCTATE, Antihemophilic Factor (Recombinant), Fc Fusion Protein, is a recombinant DNA derived, antihemophilic factor indicated in adults and children with Hemophilia A (congenital Factor VIII deficiency) for: • Control and prevention of bleeding episodes, • Perioperative management (surgical prophylaxis), • Routine prophylaxis to prevent or reduce the frequency of bleeding episodes. ELOCTATE is not indicated for the treatment of von Willebrand disease. 4 CONTRAINDICATIONS ELOCTATE is contraindicated in patients who have had life-threatening hypersensitivity reactions to ELOCTATE, including anaphylaxis. 5.1 Hypersensitivity Reactions Hypersensitivity reactions, including anaphylaxis, are possible with ELOCTATE. Early signs of hypersensitivity reactions that can progress to anaphylaxis may include angioedema, chest tightness, dyspnea, wheezing, urticaria, and pruritus. Immediately discontinue administration and initiate appropriate treatment if hypersensitivity reactions occur. 5.2 Neutralizing Antibodies Formation of neutralizing antibodies (inhibitors) to Factor VIII can occur following administration of ELOCTATE. Monitor all patients for the development of Factor VIII inhibitors by appropriate clinical observations and laboratory tests. If the plasma Factor VIII level fails to increase as expected or if bleeding is not controlled after ELOCTATE administration, suspect the presence of an inhibitor (neutralizing antibody). [see Monitoring Laboratory Tests (5.3)] 5.3 Monitoring Laboratory Tests • Monitor plasma Factor VIII activity by performing a validated test (e.g., one stage clotting assay), to confirm that adequate Factor VIII levels have been achieved and maintained. [see Dosage and Administration (2)] • Monitor for the development of Factor VIII inhibitors. Perform a Bethesda inhibitor assay if expected Factor VIII plasma levels are not attained, or if bleeding is not controlled with the expected dose of ELOCTATE. Use Bethesda Units (BU) to report inhibitor levels. 6 ADVERSE REACTIONS Common adverse reactions (≥1% of subjects) reported in clinical trials were arthralgia and malaise. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of one drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in practice. In the multi-center, prospective, open-label, clinical trial of ELOCTATE, 164 adolescent and adult, previously treated patients (PTPs, exposed to a Factor VIII containing product for ≥150 exposure days) with severe Hemophilia A (<1% endogenous FVIII activity or a genetic mutation consistent with severe Hemophilia A) received at least one dose of ELOCTATE as part of either routine prophylaxis, on-demand treatment of bleeding episodes or perioperative management. A total of 146 (89%) subjects were treated for at least 26 weeks and 23 (14%) subjects were treated for at least 39 weeks. Adverse reactions (ARs) (summarized in Table 3) were reported for nine (5.5%) subjects treated with routine prophylaxis or episodic (on-demand) therapy. Two subjects were withdrawn from study due to adverse reactions of rash and arthralgia. In the study, no inhibitors were detected and no events of anaphylaxis were reported.

It is not known whether or not ELOCTATE can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. ELOCTATE should be given to a pregnant woman only if clearly needed. 8.3 Nursing Mothers It is not known whether or not ELOCTATE is excreted into human milk. Because many drugs are excreted into human milk, caution should be exercised when ELOCTATE is administered to a nursing woman. 8.4 Pediatric Use Pharmacokinetic studies in children have demonstrated a shorter half-life and lower recovery of Factor VIII compared to adults. Because clearance (based on per kg body weight) has been shown to be significantly higher in the younger, pediatric population (2 to 5 years of age), higher and/or more frequent dosing based on body weight may be needed. [see Clinical Pharmacology (12.3)] Safety and efficacy studies have been performed in 56 previously treated, pediatric patients <18 years of age who received at least one dose of ELOCTATE as part of routine prophylaxis, on-demand treatment of bleeding episodes, or perioperative management. Adolescent subjects were enrolled in the adult and adolescent safety and efficacy trial, and subjects <12 were enrolled in an ongoing pediatric trial. Twelve subjects (21%) were <6 years of age, 31 (55%) subjects were 6 to <12 years of age, and 13 subjects (23%) were adolescents (12 to <18 years of age). Interim pharmacokinetic data from a pediatric study of the 38 subjects <12 years of age showed that no dose adjustment had been required for patients ≥6 years old. Children age 2 to 5 years had a shorter halflife and higher clearance (adjusted for body weight); therefore, a higher dose or more frequent dosing may be needed in this age group. [see Clinical Pharmacology (12.3)] 8.5 Geriatric Use Clinical studies of ELOCTATE did not include sufficient numbers of subjects aged 65 and over to determine whether or not they respond differently from younger subjects. 17 PATIENT COUNSELING INFORMATION Number of Subjects n (%) General disorders and Malaise administration site conditions Chest pain Feeling cold Feeling hot 6.2 Immunogenicity Clinical trial subjects were monitored for neutralizing antibodies to Factor VIII. No subjects developed confirmed, neutralizing antibodies to Factor VIII. One 25 year old subject had a transient, positive, neutralizing antibody of 0.73 BU at week 14, which was not confirmed upon repeat testing 18 days later and thereafter. The detection of antibodies that are reactive to Factor VIII is highly dependent on many factors, including: the sensitivity and specificity of the assay, sample handling, timing of sample collection, concomitant medications and underlying disease. 1 (0.6) 1 (0.6) Advise the patients to: • Read the FDA approved patient labeling (Patient Information and Instructions for Use) • Call their healthcare provider or go to the emergency department right away if a hypersensitivity reaction occurs. Early signs of hypersensitivity reactions may include rash, hives, itching, facial swelling, tightness of the chest, and wheezing. • Report any adverse reactions or problems following ELOCTATE administration to their healthcare provider. • Contact their healthcare provider or treatment facility for further treatment and/or assessment if they experience a lack of a clinical response to Factor VIII therapy because this may be a sign of inhibitor development. 44279-01 (continued) Manufactured by: Biogen Idec Inc. 14 Cambridge Center Cambridge, MA 02142 USA U.S. License # 1697 ELOCTATE™ is a trademark of Biogen Idec.

When you don’t have insurance, you will only get treatment when you have a bleed, which will result in increased joint disease and will increase the medical costs to the state.” Even those people with hemophilia who reside in states with the Medicaid May 2015
