Romosozumab-Aqqg

1 INDICATIONS AND USAGE EVENITY is a sclerostin inhibitor indicated for the treatment of osteoporosis in postmenopausal women at high risk for fracture, defined as a history of osteoporotic fracture, or multiple risk factors for fracture; or patients who have failed or are intolerant to other available osteoporosis therapy. ( 1 ) Limitations of Use: Limit duration of use to 12 monthly doses. If osteoporosis therapy remains warranted, continued therapy with an anti-resorptive agent should be considered. ( 1.2 ) 1.1 Treatment of Postmenopausal Women with Osteoporosis at High Risk for Fracture EVENITY is indicated for the treatment of osteoporosis in postmenopausal women at high risk for fracture, defined as a history of osteoporotic fracture, or multiple risk factors for fracture; or patients who have failed or are intolerant to other available osteoporosis therapy. 1.2 Limitations of Use The anabolic effect of EVENITY wanes after 12 monthly doses of therapy. Therefore, the duration of EVENITY use should be limited to 12 monthly doses. If osteoporosis therapy remains warranted, continued therapy with an anti-resorptive agent should be considered [see Dosage and Administration (2.2) and Clinical Studies (14.1) ] .

2 DOSAGE AND ADMINISTRATION Two separate subcutaneous injections are needed to administer the total dose of 210 mg. Inject two syringes, one after the other. ( 2.1 ) Should be administered by a healthcare provider. ( 2.1 ) Administer 210 mg subcutaneously once every month for 12 doses in the abdomen, thigh, or upper arm. ( 2.2 ) Adequately supplement calcium and vitamin D during treatment. ( 2.2 ) 2.1 Important Dosage and Administration Instructions Two separate syringes (and two separate subcutaneous injections) are needed to administer the total dose of 210 mg of EVENITY. Inject two 105 mg/1.17 mL prefilled syringes, one after the other. EVENITY should be administered by a healthcare provider. 2.2 Recommended Dosage The recommended dose of EVENITY is 210 mg administered subcutaneously in the abdomen, thigh or upper arm. Administer EVENITY once every month. The treatment duration for EVENITY is 12 monthly doses. Patients should be adequately supplemented with calcium and vitamin D during treatment with EVENITY [see Warnings and Precautions (5.3) and Clinical Studies (14.1) ] . If the EVENITY dose is missed, administer as soon as it can be rescheduled. Thereafter, EVENITY can be scheduled every month from the date of the last dose. 2.3 Preparation and Administration Instructions Administration instructions: Prefilled syringe with automatic needle guard: Step 1: Prior to Administration: Remove two syringes from the carton. Visually inspect EVENITY for particles and discoloration prior to administration. EVENITY is a clear to opalescent, colorless to light yellow solution. Do not use if the solution is cloudy or discolored or contains particles. Do not use the syringe if any part appears cracked or broken the gray needle cap is missing or not securely attached the expiration date printed on the label has passed the syringe has been dropped on a hard surface Always hold the syringe by the syringe body to remove the syringe from the tray. See Figure A . Do not grasp the plunger rod. Do not grasp the gray needle cap. Do not remove the gray needle cap until you are ready to inject. Allow EVENITY to sit at room temperature for at least 30 minutes before injecting. Do not warm in any other way [see How Supplied/Storage and Handling (16) ] . Figure A Step 2: Select the Injection Site and Prepare the Syringe Prepare and clean two injection sites, one for each of the two injections. See Figure B . Figure B The recommended subcutaneous injection sites include: The thigh Abdomen, except for a two-inch area right around the navel Outer area of upper arm Clean the injection sites with alcohol wipes. Let the skin dry. Choose a different site each time you give an injection. If you want to use the same injection site, make sure it is not the same spot on the injection site you used for a previous injection. Do not inject into areas where the skin is tender, bruised, red, or hard. Avoid injecting into areas with scars or stretch marks. Choose the first syringe. Pull the gray needle cap straight off and away from your body when you are ready to inject. See Figure C . Figure C Do not put the gray needle cap back onto the syringe. Do not leave the cap off for more than 5 minutes as this can dry out the solution. The prefilled syringe may contain air bubbles. Do not try to push air bubbles out as it is normal to see air bubbles. Step 3: Inject EVENITY Pinch the skin around the injection site before injecting. Insert the needle into the pinched skin at or about a 45-degree angle. Slowly press the plunger head all the way down with your thumb until it is completely between the needle guard clips. Do not pull back on the plunger rod at any time. Do not remove the syringe until all the medicine has been injected. Do not administer into muscle or blood vessel. See Figure D . Figure D Slowly release pressure on the plunger head with your thumb and remove the syringe from the skin. Let go of the skin after the needle is removed. Releasing the plunger head covers the used needle. See Figure E . Figure E Step 4: Syringe and Gray Needle Cap Disposal Immediately dispose of the syringe and needle cap in the nearest sharps container. Important: Repeat all steps with the second syringe to inject the full dose.

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: Major adverse cardiac events [see Boxed Warning and Warnings and Precautions (5.1) ] Hypersensitivity [see Contraindications (4) and Warnings and Precautions (5.2) ] Hypocalcemia [see Contraindications (4) and Warnings and Precautions (5.3) ] Osteonecrosis of the Jaw [see Warnings and Precautions (5.4) ] Atypical Subtrochanteric and Diaphyseal Femoral Fractures [see Warnings and Precautions (5.5) ] The most common adverse reactions (≥ 5%) reported with EVENITY in clinical trials were arthralgia and headache. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Amgen Inc. at 1-800-77-AMGEN (1-800-772-6436) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of EVENITY for the treatment of postmenopausal osteoporosis was evaluated in a multicenter, randomized, double-blind, placebo-controlled study (Study 1, NCT01575834) of 7180 postmenopausal women aged 55 to 90 years (mean age of 71 years). A total of 3581 and 3576 women received at least one dose of EVENITY and placebo, respectively, administered once every month during the 12-month double-blind study period. Women received at least 500 mg calcium and 600 international units of vitamin D supplementation daily and 77% received a loading dose of 50,000 to 60,000 international units of vitamin D within one week of randomization (if serum 25-hydroxyvitamin D concentrations were 40 ng/mL or less). The safety of EVENITY for the treatment of postmenopausal osteoporosis in patients at high risk of fracture was evaluated in a multicenter, randomized, double-blind, alendronate-controlled study (Study 2, NCT01631214) of 4093 postmenopausal women aged 55 to 90 years (mean age of 74 years). A total of 2040 and 2014 women received at least one dose of EVENITY and alendronate, respectively, during the 12-month double-blind study period. Women received at least 500 mg calcium and 600 international units vitamin D supplementation daily and 74% received a loading dose of 50,000 to 60,000 international units of vitamin D within one week of randomization (if serum 25-hydroxyvitamin D concentrations were 40 ng/mL or less). In Study 1, during the 12-month double-blind treatment period, the incidence of all-cause mortality was 0.7% (24/3576) in the placebo group and 0.8% (29/3581) in the EVENITY group. The incidence of nonfatal serious adverse events was 8.3% in the placebo group and 9.1% in the EVENITY group. The percentage of patients who withdrew from the study due to adverse events was 1.1% in the placebo group and 1.1% in the EVENITY group. The most common adverse reactions reported with EVENITY (greater than or equal to 5% and at a higher incidence than placebo) were arthralgia and headache. The most common adverse reaction leading to discontinuation of EVENITY was arthralgia (6 subjects [0.2%] in the placebo group and 5 subjects [0.1%] in the EVENITY group). In Study 2, during the 12-month double-blind treatment period, the incidence of all-cause mortality was 1.1% (22/2014) in the alendronate group and 1.5% (30/2040) in the EVENITY group. The incidence of nonfatal serious adverse events was 13.3% in the alendronate group and 11.9% in the EVENITY group. The percentage of patients who withdrew from the study due to adverse events was 1.2% in the alendronate group and 1.2% in the EVENITY group. The most common adverse reactions reported with EVENITY (greater than or equal to 5%) were arthralgia and headache. Table 1 outlines the most common adverse reactions occurring in greater than or equal to 2% of EVENITY-treated women in at least one study. Table 1. Adverse Reactions Occurring in ≥ 2% of EVENITY-Treated Women in at Least One Study (Studies 1 and 2) Study 1 Study 2 Preferred Term Placebo (N = 3576) n (%) EVENITY (N = 3581) n (%) Alendronate (N = 2014) n (%) EVENITY (N = 2040) n (%) Arthralgia 434 (12.1) 468 (13.1) 194 (9.6) 166 (8.1) Headache 208 (5.8) 235 (6.6) 110 (5.5) 106 (5.2) Muscle spasms 140 (3.9) 163 (4.6) 81 (4.0) 70 (3.4) Edema peripheral 67 (1.9) 86 (2.4) 38 (1.9) 34 (1.7) Asthenia 79 (2.2) 84 (2.3) 53 (2.6) 50 (2.5) Neck pain 54 (1.5) 80 (2.2) 42 (2.1) 34 (1.7) Insomnia 68 (1.9) 72 (2.0) 36 (1.8) 34 (1.7) Paresthesia 62 (1.7) 72 (2.0) 34 (1.7) 29 (1.4) The adverse reactions described below are from the 12-month treatment periods of Study 1 (placebo-controlled) and Study 2 (alendronate-controlled). Major Adverse Cardiac Events (MACE) During the 12-month double-blind treatment period of the placebo-controlled trial (Study 1), myocardial infarction occurred in 9 (0.3%) women in the EVENITY group and 8 (0.2%) women in the placebo group; stroke occurred in 8 (0.2%) women in the EVENITY group and 10 (0.3%) women in the placebo group . These events occurred in patients with and without a history of myocardial infarction or stroke. Cardiovascular death occurred in 17 (0.5%) women in the EVENITY group and 15 (0.4%) women in the placebo group. The number of women with positively adjudicated MACE was 30 (0.8%) in the EVENITY group and 29 (0.8%) in the placebo group, yielding a hazard ratio of 1.03 (95% confidence interval [0.62, 1.72]) for EVENITY compared to placebo. During the 12-month double-blind treatment period of the active-controlled trial (Study 2), myocardial infarction occurred in 16 (0.8%) women in the EVENITY group and 5 (0.2%) women in the alendronate group; stroke occurred in 13 (0.6%) women in the EVENITY group and 7 (0.3%) women in the alendronate group. These events occurred in patients with and without a history of myocardial infarction or stroke. Cardiovascular death occurred in 17 (0.8%) women in the EVENITY group and 12 (0.6%) women in the alendronate group. The number of women with positively adjudicated MACE was 41 (2.0%) in the EVENITY group and 22 (1.1%) in the alendronate group, yielding a hazard ratio of 1.87 (95% confidence interval [1.11, 3.14]) for EVENITY compared to alendronate [see Boxed Warning and Warnings and Precautions (5.1) ]. Hypersensitivity Reactions Across both trials, hypersensitivity reactions were reported in 364 (6.5%) women in the EVENITY group and 365 (6.5%) women in the control group. Reported reactions included angioedema (3 [< 0.1%] women in the EVENITY group vs. 3 [< 0.1%] women in the control group), erythema multiforme (1 [< 0.1%] woman in the EVENITY group vs. no woman in the control group), dermatitis (32 [0.6%] women in the EVENITY group vs. 42 [0.8%] women in the control group), rash (60 [1.1%] women in the EVENITY group vs. 53 [0.9%] women in the control group), and urticaria (23 [0.4%] women in the EVENITY group vs. 27 [0.5%] women in the control group). Although angioedema, dermatitis and urticaria were not reported at a higher incidence with EVENITY than control, there were cases of angioedema, dermatitis and urticaria that were determined to be related to EVENITY use [see Contraindications (4) and Warnings and Precautions (5.2) ] . Hypocalcemia Across both trials, adverse events of hypocalcemia occurred in 2 EVENITY-treated women and in 1 woman in the control group. Decreases in albumin-adjusted serum calcium to below the lower limit of the reference range (8.3 mg/dL) were reported in 14 (0.2%) women in the EVENITY group and 10 (0.2%) women in the control group. No patient receiving EVENITY developed serum calcium less than 7.5 mg/dL. The nadir in albumin-adjusted serum calcium occurred by month 1 after EVENITY dosing in patients with normal renal function [see Contraindications (4) and Warnings and Precautions (5.3) ] . Injection Site Reactions Across both trials, injection site reactions occurred in 278 (4.9%) women in the EVENITY group and 157 (2.8%) women in the control group. The most common injection site reactions were pain (94 [1.7%] women in the EVENITY group; 70 [1.3%] women in the control group) and erythema (80 [1.4%] women in the EVENITY group and 14 [0.3%] women in the control group). Injection site reactions resulted in discontinuation of treatment in 7 (0.1%) EVENITY-treated patients and 3 (< 0.1%) patients in the control group. Osteonecrosis of the Jaw Across both trials, osteonecrosis of the jaw occurred in one patient during treatment with EVENITY [see Warnings and Precautions (5.4) ]. Atypical Subtrochanteric and Diaphyseal Fractures Across both trials, atypical femoral fracture occurred in one patient during treatment with EVENITY [see Warnings and Precautions (5.5) ].

12.3 Pharmacokinetics Administration of a single dose of 210 mg EVENITY in healthy volunteers resulted in a mean (standard deviation [SD]) maximum romosozumab-aqqg serum concentration (C max ) of 22.2 (5.8) mcg/mL and a mean (SD) AUC of 389 (127) mcg*day/mL. Steady-state concentrations were achieved by month 3 following the monthly administration of 210 mg to postmenopausal women. The mean trough serum romosozumab-aqqg concentrations at months 3, 6, 9, and 12 ranged from 8 to 13 mcg/mL. Romosozumab-aqqg exhibited nonlinear pharmacokinetics with exposure increasing greater than dose proportionally (e.g., 550-fold increase in mean AUC inf for the 100-fold increase in subcutaneous doses ranging from 0.1 to 10 mg/kg 0.03 to 3.3 times the approved recommended dosage for a 70 kg woman). Absorption The median time to maximum romosozumab-aqqg concentration (T max ) is 5 days (range: 2 to 7 days). Distribution The estimated volume of distribution at steady-state is approximately 3.92 L. Elimination Romosozumab-aqqg exhibited nonlinear pharmacokinetics with the clearance of romosozumab-aqqg decreasing as the dose increased. The estimated mean systemic clearance (CL/F) of romosozumab-aqqg was 0.38 mL/hr/kg, following a single subcutaneous administration of 3 mg/kg (the approved recommended dosage for a 70 kg woman). The mean effective t 1/2 was 12.8 days after 3 doses of 3 mg/kg (the approved recommended dosage for a 70 kg woman) every 4 weeks. Metabolism The metabolic pathway of romosozumab-aqqg has not been characterized. As a humanized IgG2 monoclonal antibody, romosozumab-aqqg is expected to be degraded into small peptides and amino acids via catabolic pathways in a manner similar to endogenous IgG. Specific Populations No clinically significant differences in the pharmacokinetics of romosozumab-aqqg were observed based on age (20-89 years), sex, race, disease state (low bone mass or osteoporosis), prior exposure to alendronate, or renal impairment including end-stage renal disease (ESRD) requiring dialysis. The effect of ESRD not requiring dialysis on the pharmacokinetics of romosozumab-aqqg is unknown. Body Weight The exposure of romosozumab-aqqg decreases with increasing body weight.
