2 DOSAGE AND ADMINISTRATION Hydrate prior to and following Kyprolis as needed. ( 2.1 ) Premedicate prior to all Cycle 1 doses and if infusion-related reactions develop or reappear. ( 2.1 ) The recommended dosing regimens are as follows. See Full Prescribing Information for additional dosage information. ( 2.2 ) Regimen Dosage Infusion Time Kyprolis and Dexamethasone (Kd) or Kyprolis, Daratumumab and Dexamethasone (DKd) or Kyprolis, Daratumumab and hyaluronidase-fihj and Dexamethasone (DKd) 20/70 mg/m 2 once weekly 30 minutes Kyprolis and Dexamethasone (Kd) or Kyprolis, Daratumumab and Dexamethasone (DKd) or Kyprolis, Daratumumab and hyaluronidase-fihj and Dexamethasone (DKd) or Kyprolis, Isatuximab and Dexamethasone (Isa-Kd) or Kyprolis Monotherapy 20/56 mg/m 2 twice weekly 30 minutes Kyprolis, Lenalidomide and Dexamethasone (KRd) or Kyprolis Monotherapy 20/27 mg/m 2 twice weekly 10 minutes 2.1 Administration Precautions Hydration Adequate hydration is required prior to dosing in Cycle 1, especially in patients at high-risk of tumor lysis syndrome (TLS) or renal toxicity. Consider hydration with both oral fluids (30 mL per kg at least 48 hours before Cycle 1, Day 1) and intravenous fluids (250 mL to 500 mL of appropriate intravenous fluid prior to each dose in Cycle 1). If needed, give an additional 250 mL to 500 mL of intravenous fluids following Kyprolis administration. Continue oral and/or intravenous hydration, as needed, in subsequent cycles. Monitor patients for evidence of volume overload and adjust hydration to individual patient needs, especially in patients with or at risk for cardiac failure [see Warnings and Precautions (5.1 , 5.3) ] . Electrolyte Monitoring Monitor serum potassium levels regularly during treatment with Kyprolis [see Adverse Reactions (6.1) ] . Premedications and Concomitant Medications Premedicate with the recommended dose of dexamethasone for monotherapy or dexamethasone administered as part of the combination therapy [see Dosage and Administration (2.2) ] . Administer dexamethasone orally or intravenously at least 30 minutes but no more than 4 hours prior to all doses of Kyprolis during Cycle 1 to reduce the incidence and severity of infusion-related reactions [see Warnings and Precautions (5.9) ] . Reinstate dexamethasone premedication if these symptoms occur during subsequent cycles. Provide thromboprophylaxis for patients being treated with Kyprolis in combination with other therapies [see Warnings and Precautions (5.8) ] . Consider antiviral prophylaxis to decrease the risk of herpes zoster reactivation [see Adverse Reactions (6.1) ] . Dose Calculation For patients with body surface area (BSA) of 2.2 m 2 or less, calculate the Kyprolis dose using actual BSA. Dose adjustments do not need to be made for weight changes of 20% or less. For patients with a BSA greater than 2.2 m 2 , calculate the Kyprolis dose using a BSA of 2.2 m 2 . 2.2 Recommended Dosage Once Weekly 20/70 mg/m 2 (30-minute infusion) Kyprolis once weekly 20/70 mg/m 2 administered in combination with dexamethasone (Kd), daratumumab plus dexamethasone (DKd), or daratumumab and hyaluronidase-fihj plus dexamethasone (DKd). The recommended starting dosage of Kyprolis is 20 mg/m 2 on Cycle 1, Day 1. If tolerated, escalate the dose to 70 mg/m 2 on Cycle 1, Day 8. Administer Kyprolis intravenously as a 30-minute infusion on Days 1, 8, and 15 of each 28-day cycle until disease progression or unacceptable toxicity as shown in Table 1 [see Clinical Studies (14.2) ] . Administer dexamethasone 30 minutes to 4 hours before Kyprolis and 1 to 3 hours before daratumumab or daratumumab and hyaluronidase-fihj. For dosage instructions of combination agents with Kyprolis, see Clinical Studies sections 14.2 (Kd) and 14.3 (DKd) . Refer to the Prescribing Information for dexamethasone, intravenous daratumumab, and subcutaneous daratumumab and hyaluronidase-fihj for additional dosage information.

5 WARNINGS AND PRECAUTIONS Cardiac Toxicities : Monitor for signs and symptoms of cardiac failure or ischemia. Withhold Kyprolis and evaluate promptly. ( 5.1 ) Acute Renal Failure : Monitor serum creatinine regularly. ( 5.2 ) Tumor Lysis Syndrome (TLS) : Administer pre-treatment hydration. (2.1 ) Monitor for TLS, including uric acid levels and treat promptly. ( 5.3 ) Pulmonary Toxicity, including Acute Respiratory Distress Syndrome, Acute Respiratory Failure, and Acute Diffuse Infiltrative Pulmonary Disease : Withhold Kyprolis and evaluate promptly. ( 5.4 ) Pulmonary Hypertension : Withhold Kyprolis and evaluate. ( 5.5 ) Dyspnea : For severe or life-threatening dyspnea, withhold Kyprolis and evaluate. ( 5.6 ) Hypertension, including Hypertensive Crisis : Monitor blood pressure regularly. If hypertension cannot be controlled, interrupt treatment with Kyprolis. ( 5.7 ) Venous Thrombosis : Thromboprophylaxis is recommended. ( 5.8 ) Infusion-related Reactions : Premedicate with dexamethasone. ( 2.1 , 5.9 ) Hemorrhage : Fatal or serious cases of hemorrhage may occur, including gastrointestinal, pulmonary, and intracranial hemorrhage. Promptly evaluate signs and symptoms of blood loss. ( 5.10 ) Thrombocytopenia : Monitor platelet counts; interrupt or reduce Kyprolis dosing as clinically indicated. ( 2.3 , 5.11 ) Hepatic Toxicity and Hepatic Failure : Monitor liver enzymes regularly. Withhold Kyprolis if suspected. ( 5.12 ) Thrombotic Microangiopathy : Monitor for signs and symptoms. Discontinue Kyprolis if suspected. ( 5.13 ) Posterior Reversible Encephalopathy Syndrome (PRES) : Consider neuro-radiological imaging (MRI) for onset of visual or neurological symptoms; discontinue Kyprolis if suspected. ( 5.14 ) Progressive Multifocal Leukoencephalopathy : Consider PML if new or worsening neurologic manifestations. Discontinue Kyprolis in patients who develop PML. ( 5.15 ) Increased Fatal and Serious Toxicities in Combination with Melphalan and Prednisone in Newly Diagnosed Transplant-Ineligible Patients ( 5.16 ) Embryo-Fetal Toxicity : Kyprolis can cause fetal harm. Advise females of reproductive potential and males with female partners of reproductive potential of potential risk to a fetus and to use effective contraception. ( 5.17 , 8.1 ) 5.1 Cardiac Toxicities New onset or worsening of pre-existing cardiac failure (e.g., congestive heart failure, pulmonary edema, decreased ejection fraction), cardiomyopathy, myocardial ischemia, and myocardial infarction including fatalities have occurred following administration of Kyprolis. Some events occurred in patients with normal baseline ventricular function. In clinical studies with Kyprolis, these events occurred throughout the course of Kyprolis therapy. Death due to cardiac arrest has occurred within one day of Kyprolis administration. In randomized, open-label, multicenter trials for combination therapies, the incidence of cardiac failure events was 8% and that of arrythmias was 8% (majority of which were atrial fibrillation and sinus tachycardia) [see Adverse Reactions (6.1) ]. Monitor patients for clinical signs or symptoms of cardiac failure or cardiac ischemia. Evaluate promptly if cardiac toxicity is suspected. Withhold Kyprolis for Grade 3 or 4 cardiac adverse reactions until recovery and consider whether to restart Kyprolis at 1 dose level reduction based on a benefit/risk assessment [see Dosage and Administration (2.3) ] . While adequate hydration is required prior to each dose in Cycle 1, monitor all patients for evidence of volume overload, especially patients at risk for cardiac failure. Adjust total fluid intake as clinically appropriate in patients with baseline cardiac failure or who are at risk for cardiac failure [see Dosage and Administration (2.1) ] . In patients ≥ 75 years of age, the risk of cardiac failure is increased compared to younger patients. Patients with New York Heart Association Class III and IV heart failure, recent myocardial infarction, conduction abnor…

8.1 Pregnancy Risk Summary Kyprolis can cause fetal harm based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1) ] . There are no available data on Kyprolis use in pregnant women to evaluate for drug-associated risks. Kyprolis caused embryo-fetal lethality in rabbits at doses lower than the clinical dose (see Data ) . Advise pregnant women of the potential risk to the fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%–4% and 15%–20%, respectively. Data Animal Data Carfilzomib administered intravenously to pregnant rats and rabbits during the period of organogenesis was not teratogenic at doses up to 2 mg/kg/day in rats and 0.8 mg/kg/day in rabbits. In rabbits, there was an increase in pre-implantation loss at ≥ 0.4 mg/kg/day and an increase in early resorptions and post-implantation loss and a decrease in fetal weight at the maternally toxic dose of 0.8 mg/kg/day. The doses of 0.4 and 0.8 mg/kg/day in rabbits are approximately 20% and 40%, respectively, of the recommended dose in humans of 27 mg/m 2 based on BSA.

The pooled safety population described in the Warnings and Precautions reflect exposure to Kyprolis in 2,239 patients administered in combination with other drugs in ASPIRE, ENDEAVOR, A.R.R.O.W., CANDOR, IKEMA, EQUULEUS, and PLEIADES. The most common adverse reactions occurring in at least 20% of patients who received Kyprolis in combination were anemia, diarrhea, hypertension, fatigue, upper respiratory tract infection, thrombocytopenia, pyrexia, cough, dyspnea, and insomnia. Kyprolis in Combination with Lenalidomide and Dexamethasone The safety of Kyprolis 20/27 mg/m 2 twice weekly in combination with lenalidomide and dexamethasone (KRd) was evaluated in ASPIRE [see Clinical Studies (14.1) ] . The median number of cycles initiated was 22 cycles for the KRd arm and 14 cycles for the Rd arm. Deaths due to adverse reactions within 30 days of the last dose of any therapy in the KRd arm occurred in 45/392 (12%) patients compared with 42/389 (11%) patients who died due to adverse reactions within 30 days of the last dose of any Rd therapy. The most frequent cause of deaths occurring in patients (%) in the two arms (KRd versus Rd) included infection 12 (3%) versus 11 (3%), cardiac 10 (3%) versus 9 (2%), and other adverse reactions 23 (6%) versus 22 (6%). Serious adverse reactions were reported in 65% of the patients in the KRd arm and 57% of the patients in the Rd arm. The most frequent serious adverse reactions reported in the KRd arm as compared with the Rd arm were pneumonia (17% versus 13%), respiratory tract infection (4% versus 2%), pyrexia (4% versus 3%), and pulmonary embolism (3% versus 2%). Discontinuation due to any adverse reaction occurred in 33% in the KRd arm versus 30% in the Rd arm. Adverse reactions leading to discontinuation of Kyprolis occurred in 12% of patients and the most common reactions included pneumonia (1%), myocardial infarction (0.8%), and upper respiratory tract infection (0.8%). The incidence of cardiac failure events was 7% in the KRd arm versus…
