1 Parsabiv the control of calcimimetic delivery you ve always wanted, the sustained lowering of shpt lab values your patients deserve 1 Not an actual Parsabiv vial. The displayed vial is for illustrative purposes only. Indication Parsabiv (etelcalcetide) is indicated for the treatment of secondary hyperparathyroidism (HPT) in adult patients with chronic kidney disease (CKD) on hemodialysis. Limitations of Use: Parsabiv has not been studied in adult patients with parathyroid carcinoma, primary hyperparathyroidism, or with CKD who are not on hemodialysis and is not recommended for use in these populations. Parsabiv is contraindicated in patients with known hypersensitivity to etelcalcetide or any of its excipients. Hypersensitivity reactions, including pruritic rash, urticaria, and face edema, have occurred. Please see additional Important Safety Information on page 15. shpt = secondary hyperparathyroidism.

3 About Parsabiv Parsabiv gives you control over calcimimetic delivery at the end of hemodialysis 1 CONTROL delivery with IV administration 1 What are the fundamentals of Parsabiv? Not an actual Parsabiv vial. The displayed vial is for illustrative purposes only. Significant lowering of serum calcium can cause QT interval prolongation and ventricular arrhythmia. Patients with conditions that predispose to QT interval prolongation and ventricular arrhythmia may be at increased risk for QT interval prolongation and ventricular arrhythmias if they develop hypocalcemia due to Parsabiv. Closely monitor corrected serum calcium and QT interval in patients at risk on Parsabiv. Please see additional on page 15. PTH P cca LOWER 3 key secondary HPT lab values 1 * PTH P cca MAINTAIN lab reductions up to 78 weeks 1 * Results are combined from two 26-week, randomized, double-blind, placebo-controlled studies comparing Parsabiv with placebo in patients with chronic kidney disease (CKD) on hemodialysis. Open-label extension (OLE): data pooled for patients receiving Parsabiv across two placebo-controlled parent studies and a subsequent OLE study, starting from the baseline of the parent study until the end or the prespecified cutoff date of the OLE study, whichever was earlier. 2 P = phosphate; cca = corrected calcium; IV = intravenous. 4 5

4 Combined Placebo-Controlled Studies 78% of patients who received Parsabiv achieved > 30% reduction in mean PTH 3 What effect does Parsabiv have on parathyroid hormone (PTH) levels? Significant reductions in corrected serum calcium may lower the threshold for seizures. Patients with a history of seizure disorder may be at increased risk for seizures if they develop hypocalcemia due to Parsabiv. Monitor corrected serum calcium in patients with seizure disorders on Parsabiv. Please see additional on page 15. % of patients achieving > 30% reduction in mean ipth from baseline % Parsabiv + vitamin D and/or phosphate binders* (n = 509) 11.1 % P < Placebo + vitamin D and/or phosphate binders* (n = 514) Results are combined from two 26-week, randomized, double-blind, placebo-controlled studies comparing Parsabiv with placebo in patients with chronic kidney disease (CKD) on hemodialysis with intact parathyroid hormone (ipth) > 400 pg/ml and corrected calcium 8.3 mg/dl (N = 1023). Patients in both treatment arms could be treated with vitamin D sterols and/or phosphate binders. Mean baseline ipth in the Parsabiv group and placebo group were 847 pg/ml and 836 pg/ml, respectively. The primary endpoint of each study was the proportion of patients who achieved a > 30% reduction from baseline in mean ipth during the efficacy assessment period (defined as weeks 20 through 27, inclusive). 1,2,4 * Vitamin D and/or phosphate binders, if prescribed

Patients switching from cinacalcet to Parsabiv should discontinue cinacalcet for at least 7 days prior to initiating Parsabiv. Closely monitor corrected serum calcium in patients receiving Parsabiv and concomitant therapies known to lower serum calcium. Please see additional on page 15. Parsabiv + vitamin D and phosphate binders* Screening ipth Placebo + vitamin D and phosphate binders* Secondary endpoint: in phase 3 trials, overall, 53.4% of Parsabiv patients achieved ipth 300 pg/ml vs 5.8% of placebo patients during the efficacy assessment period (P < 0.001) 3 Results are combined from two 26-week, randomized, double-blind, placebo-controlled studies comparing Parsabiv with placebo in patients with CKD on hemodialysis with ipth > 400 pg/ml and corrected calcium 8.3 mg/dl (N = 1023). Patients in both treatment arms could be treated with vitamin D sterols and/or phosphate binders. Mean baseline ipth in the Parsabiv group and placebo group were 847 pg/ml and 836 pg/ml, respectively. The primary endpoint of each study was the proportion of patients who achieved a > 30% reduction from baseline in mean ipth during the efficacy assessment period (defined as weeks 20 through 27, inclusive). 1,2,4 * Vitamin D and/or phosphate binders, if prescribed. 4 Overall, the average dose of Parsabiv during the efficacy assessment period was 7.2 mg three times per week 1 Patients initiated at screening ipth < 600 pg/ml had an average dose of 5.7 mg three times per week 1 Patients initiated at screening ipth 600 to 1000 pg/ml had an average dose of 7.4 mg three times per week 1 Patients initiated at screening ipth > 1000 pg/ml had an average dose of 8.7 mg three times per week 1 8 9

6 Combined Placebo-Controlled and Open-Label Extension Studies What impact does Parsabiv have on PTH, phosphate, and corrected calcium levels? Measure corrected serum calcium prior to initiation of Parsabiv. Do not initiate in patients if the corrected serum calcium is less than the lower limit of normal. Monitor corrected serum calcium within 1 week after initiation or dose adjustment and every 4 weeks during treatment with Parsabiv. Measure PTH 4 weeks after initiation or dose adjustment of Parsabiv. Once the maintenance dose has been established, measure PTH per clinical practice. Please see additional on page 15.

7 Adverse Reactions Adverse reactions reported in 5% of Parsabiv -treated patients 1 Combined placebo-controlled studies Parsabiv (N = 503) Placebo (N = 513) What adverse reactions were experienced in Parsabiv combined phase 3 studies? Please see on page 15. Adverse Reaction* Blood calcium decreased Muscle spasms Diarrhea Nausea Vomiting Headache Hypocalcemia Paresthesia % % * Included adverse reactions reported with at least 1% greater incidence in the Parsabiv group compared to the placebo group. Asymptomatic reductions in corrected serum calcium between 8.3 mg/dl and > 7.5 mg/dl (clinically significant reductions that required medical management) or reductions in calcium below 7.5 mg/dl. Symptomatic reductions in corrected serum calcium < 8.3 mg/dl. Paresthesia includes preferred terms of paresthesia and hypoesthesia. Discontinuations Overall, in placebo-controlled studies, 1.8% of patients in the Parsabiv group and 2.5% of patients in the placebo group discontinued treatment due to an adverse event 7 Low serum calcium Most events of blood calcium decrease or hypocalcemia were mild or moderate in severity in both the placebo and Parsabiv groups 7,8 In combined placebo-controlled studies, 1% of patients who received Parsabiv discontinued treatment due to low corrected serum calcium vs 0% with placebo

8 What safety information for Parsabiv do I need to know? Contraindication: Parsabiv is contraindicated in patients with known hypersensitivity to etelcalcetide or any of its excipients. Hypersensitivity reactions, including pruritic rash, urticaria, and face edema, have occurred. Hypocalcemia: Parsabiv lowers serum calcium and can lead to hypocalcemia, sometimes severe. Significant lowering of serum calcium can cause QT interval prolongation and ventricular arrhythmia. Patients with conditions that predispose to QT interval prolongation and ventricular arrhythmia may be at increased risk for QT interval prolongation and ventricular arrhythmias if they develop hypocalcemia due to Parsabiv. Closely monitor corrected serum calcium and QT interval in patients at risk on Parsabiv. Significant reductions in corrected serum calcium may lower the threshold for seizures. Patients with a history of seizure disorder may be at increased risk for seizures if they develop hypocalcemia due to Parsabiv. Monitor corrected serum calcium in patients with seizure disorders on Parsabiv. Concurrent administration of Parsabiv with another oral calcimimetic could result in severe, life-threatening hypocalcemia. Patients switching from cinacalcet to Parsabiv should discontinue cinacalcet for at least 7 days prior to initiating Parsabiv. Closely monitor corrected serum calcium in patients receiving Parsabiv and concomitant therapies known to lower serum calcium. Measure corrected serum calcium prior to initiation of Parsabiv. Do not initiate in patients if the corrected serum calcium is less than the lower limit of normal. Monitor corrected serum calcium within 1 week after initiation or dose adjustment and every 4 weeks during treatment with Parsabiv. Measure PTH 4 weeks after initiation or dose adjustment of Parsabiv. Once the maintenance dose has been established, measure PTH per clinical practice. Worsening Heart Failure: In Parsabiv clinical studies, cases of hypotension, congestive heart failure, and decreased myocardial performance have been reported. Closely monitor patients treated with Parsabiv for worsening signs and symptoms of heart failure. Upper Gastrointestinal Bleeding: In clinical studies, 2 patients treated with Parsabiv in 1253 patient years of exposure had upper gastrointestinal (GI) bleeding at the time of death. The exact cause of GI bleeding in these patients is unknown and there were too few cases to determine whether these cases were related to Parsabiv. Patients with risk factors for upper GI bleeding, such as known gastritis, esophagitis, ulcers or severe vomiting, may be at increased risk for GI bleeding with Parsabiv. Monitor patients for worsening of common Parsabiv GI adverse reactions and for signs and symptoms of GI bleeding and ulcerations during Parsabiv therapy. Adynamic Bone: Adynamic bone may develop if PTH levels are chronically suppressed. Adverse Reactions: In clinical trials of patients with secondary HPT comparing Parsabiv to placebo, the most common adverse reactions were blood calcium decreased (64% vs. 10%), muscle spasms (12% vs. 7%), diarrhea (11% vs. 9%), nausea (11% vs. 6%), vomiting (9% vs. 5%), headache (8% vs. 6%), hypocalcemia (7% vs. 0.2%), and paresthesia (6% vs. 1%). Please see accompanying Parsabiv full Prescribing Information

9 How to Switch to Parsabiv Patients must discontinue Sensipar (cinacalcet) for at least 7 days before starting Parsabiv How to switch from Sensipar to Parsabiv Ensure your patient discontinues use of Sensipar tablets for at least 7 days prior to starting Parsabiv. 1 What if my patients are currently on Sensipar (cinacalcet) and want to switch to Parsabiv? 7-day discontinuation of Sensipar Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 Pills are not actual size In Parsabiv clinical studies, cases of hypotension, congestive heart failure, and decreased myocardial performance have been reported. Closely monitor patients treated with Parsabiv for worsening signs and symptoms of heart failure. Please see additional on page 15. Initiate Parsabiv * Lower limit of reference range in phase 3 trials was 8.3 mg/dl. 1,4 after day 7, if corrected serum calcium is at or above lower limit of normal* 16 17

10 Initiating Parsabiv Initiating patients on Parsabiv 5 mg 3x starting dose a week During rinse back or IV after rinse back How do I start my patients on Parsabiv? Ensure corrected serum calcium is at or above the lower limit of normal prior to Parsabiv initiation, a dose increase, or reinitiation after dosing interruption 1 Initiate Parsabiv at 5 mg, 3 times per week 1 Administer Parsabiv by intravenous bolus injection into the venous line of the dialysis circuit at the end of the hemodialysis treatment during rinse back or IV after rinse back 1 Do not administer Parsabiv more frequently than 3 times per week 1 In clinical studies, 2 patients treated with Parsabiv in 1253 patient years of exposure had upper gastrointestinal (GI) bleeding at the time of death. The exact cause of GI bleeding in these patients is unknown and there were too few cases to determine whether these cases were related to Parsabiv. Please see additional on page 15. Parsabiv is available in 3 different, single-use, single-dose vials 2.5mg/ 0.5mL 5mg/ 1mL Vials shown are actual size 10mg/ 2mL If a regularly scheduled hemodialysis treatment is missed, DO NOT administer any missed doses. Resume Parsabiv at the end of the next hemodialysis treatment at the prescribed dose 1 If doses of Parsabiv are missed for more than 2 weeks, reinitiate Parsabiv at the recommended starting dose of 5 mg (or 2.5 mg if that was the patient s last dose)

11 Lab Monitoring and Titration Flexible dosing that you control with IV administration 1 Lab monitoring during Parsabiv treatment PTH Corrected Serum Calcium Lab measurements after initiation or dose adjustment after 4 weeks at 1 week How do I monitor and titrate Parsabiv? Lab measurements once maintenance dose is established per clinical practice every 4 weeks Patients with risk factors for upper GI bleeding, such as known gastritis, esophagitis, ulcers or severe vomiting, may be at increased risk for GI bleeding with Parsabiv. Monitor patients for worsening of common Parsabiv GI adverse reactions and for signs and symptoms of GI bleeding and ulcerations during Parsabiv therapy. Please see additional on page 15. Titrate up or down as needed based on PTH and corrected serum calcium Titrating up: Increase the dose of Parsabiv in 2.5 mg or 5 mg increments until PTH is within recommended target range and corrected serum calcium is within normal range Increase no more frequently than every 4 weeks up to a maximum dose of 15 mg three times per week Titrating down: Decrease or temporarily discontinue Parsabiv when PTH is below target range Consider decreasing or temporarily discontinuing Parsabiv, or use concomitant therapies,* when corrected serum calcium is below lower limit of normal but 7.5 mg/dl without symptoms of hypocalcemia 15 mg 12.5 mg 10 mg 7.5 mg 5 mg 2.5 mg MAXIMUM DOSE Titrate up or down STARTING DOSE Reinitiating Parsabiv : If dose is stopped, reinitiate Parsabiv at a lower dose when PTH is within target range and hypocalcemia has been corrected * Concomitant therapies include calcium, calcium-containing phosphate binders, and/or vitamin D sterols or increases in dialysate calcium concentration. Lower limit of reference range in phase 3 trials was 8.3 mg/dl. 1,

12 Managing Calcium Managing calcium in patients taking Parsabiv 1 Do not initiate Parsabiv if corrected serum calcium is less than the lower limit of normal* Monitor corrected serum calcium within 1 week after initiation or dose adjustment and every 4 weeks during treatment with Parsabiv. Educate patients on the symptoms of hypocalcemia and advise them to contact a healthcare provider if they occur 8.3 mg/dl* Initiate Parsabiv How do I manage calcium levels in patients on Parsabiv? < 8.3 mg/dl to 7.5 mg/dl* without symptoms of hypocalcemia Adjust Treatment as Needed Consider decreasing or temporarily discontinuing Parsabiv or use concomitant therapies to increase corrected serum calcium (including calcium, calcium-containing phosphate binders, and/or vitamin D sterols or increases in dialysate calcium concentration) Adynamic bone may develop if PTH levels are chronically suppressed. Please see additional on page 15. < 7.5 mg/dl or with symptoms of hypocalcemia Withhold Parsabiv and Monitor Stop Parsabiv and treat hypocalcemia Start or increase calcium supplementation (including calcium, calcium-containing phosphate binders, and/ or vitamin D sterols or increases in dialysate calcium concentration) Throughout the studies, dialysate calcium concentration could be adjusted but had to remain 2.25 meq/l 1 Significant lowering of serum calcium can cause paresthesias, myalgias, muscle spasms, seizures, QT interval prolongation, and ventricular arrhythmias 1 * Lower limit of reference range in phase 3 trials was 8.3 mg/dl. 1,4 When cca returns 8.3 mg/dl* Reinitiate Parsabiv When corrected serum calcium levels are within normal limits, symptoms of hypocalcemia have resolved, and predisposing factors for hypocalcemia have been addressed, reinitiate Parsabiv at a dose 5 mg lower than the last administered dose. If patient s last administered dose of Parsabiv was 2.5 mg or 5 mg, reinitiate at a dose of 2.5 mg 22 23

13 Managing Calcium Calcium reductions were most prominent early in treatment 5 Mean corrected calcium was maintained above the lower limit of normal for up to 78 weeks Return to baseline after 4-week discontinuation 2,5 * How might I expect calcium levels to change in response to Parsabiv? Mean corrected calcium (mg/dl) In clinical trials of patients with secondary HPT comparing Parsabiv to placebo, the most common adverse reactions were blood calcium decreased (64% vs. 10%), muscle spasms (12% vs. 7%), diarrhea (11% vs. 9%), nausea (11% vs. 6%), vomiting (9% vs. 5%), headache (8% vs. 6%), hypocalcemia (7% vs. 0.2%), and paresthesia (6% vs. 1%). Please see additional on page Placebo-controlled parent study period 30-day washout phase Study week Open-label extension study period Parsabiv n = 509 n = 436 n = 381 n = 146 Refer to recommendations on monitoring and managing calcium in patients taking Parsabiv on page 23 Placebo-controlled treatment period: results are combined from two 26-week, randomized, double-blind, placebo-controlled studies comparing Parsabiv with placebo in patients with CKD on hemodialysis with ipth > 400 pg/ml and corrected calcium 8.3 mg/dl (N = 1023). Patients in both treatment arms could be treated with vitamin D sterols and/or phosphate binders. Mean baseline ipth in the Parsabiv group and placebo group were 847 pg/ml and 836 pg/ml, respectively. The primary endpoint of each study was the proportion of patients who achieved a > 30% reduction from baseline in mean ipth during the efficacy assessment period (defined as weeks 20 through 27, inclusive). 1,2,4 Open-label extension: data pooled for patients receiving Parsabiv across two placebo-controlled parent studies and a subsequent open-label extension (OLE) study, starting from the baseline of the parent study until the end or the prespecified cutoff date of the OLE study, whichever was earlier. Weeks 27 to 31 were the 30-day drug-free period (the 30-day follow-up period of the phase 3 study before entry into the extension study). 2 During the OLE, the starting dose of Parsabiv for all subjects was 5 mg. The Parsabiv dose could be increased at OLE weeks 5, 9, 17, 25, 33, 41, and 49 to a maximum dose of 15 mg to achieve predialysis serum ipth 300 pg/ml while maintaining appropriate serum cca concentrations. Investigators were blinded to ipth results during the first 10 weeks of treatment. Subsequent dose adjustment was determined by the investigator per protocol guidelines. 9 * Starting at week 27, no study drug was administered as part of a 30-day follow-up while patients transitioned studies. 2 Value represents cca measured at the first hemodialysis session in week
