Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug, and may not reflect the rates observed in medical practice.

The safety of Кипролис in combination with lenalidomide and dexamethasone (KRd) was evaluated in an open-label randomized study in patients with relapsed multiple myeloma. Â Details of the study treatment are described in Section 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 27/392 (7%) patients compared with 27/389 (7%) patients who died due to adverse events within 30 days of the last dose of any Rd therapy. The most common cause of deaths occurring in patients (%) in the two arms (KRd versus Rd) included cardiac 10 (3%) versus 7 (2%), infection 9 (2%) versus 10 (3%), renal 0 (0%) versus 1 (< 1%), and other adverse reactions 9 (2%) versus 10 (3%). Serious adverse reactions were reported in 60% of the patients in the KRd arm and 54% of the patients in the Rd arm. The most common serious adverse reactions reported in the KRd arm as compared with the Rd arm were pneumonia (14% versus 11%), respiratory tract infection (4% versus 1.5%), pyrexia (4% versus 2%), and pulmonary embolism (3% versus 2%). Discontinuation due to any adverse reaction occurred in 26% in the KRd arm versus 25% in the Rd arm. Adverse reactions leading to discontinuation of Кипролис 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 adverse reactions in the first 12 cycles of therapy that occurred at a rate of 10% or greater in the KRd arm are presented in Table 8.

Table 8: Most Common Adverse Reactions (≥ 10% in the KRd Arm) Occurring in Cycles 1–12 (20/27 mg/m² Regimen In Combination with Lenalidomide and Dexamethasone)

Table 9 describes Grade 3–4 laboratory abnormalities reported at a rate of ≥ 10% in the KRd arm for patients who received combination therapy.

Table 9: Grade 3–4 Laboratory Abnormalities (≥ 10% in the KRd Arm) in Cycles 1–12 (20/27 mg/m² Regimen In Combination with Lenalidomide and Dexamethasone)

The safety of Кипролис in combination with dexamethasone was evaluated in an open-label, randomized trial of patients with relapsed multiple myeloma. The study treatment is described in Section 14.2. Patients received treatment for a median duration of 48 weeks in the Кипролис/dexamethasone (Kd) arm and 27 weeks in the bortezomib/dexamethasone (Vd) arm.

Deaths due to adverse reactions within 30 days of last study treatment occurred in 32/463 (7%) patients in the Kd arm and 21/456 (5%) patients in the Vd arm. The causes of death occurring in patients (%) in the two arms (Kd versus Vd) included cardiac 4 (1%) versus 5 (1%), infections 8 (2%) versus 8 (2%), disease progression 7 (2%) versus 4 (1%), pulmonary 3 (1%) versus 2 (< 1%), renal 1 (< 1%) versus 0 (0%), and other adverse events 9 (2%) versus 2 (< 1%). Serious adverse reactions were reported in 59% of the patients in the Kd arm and 40% of the patients in the Vd arm. In both treatment arms, pneumonia was the most commonly reported serious adverse reaction (8% versus 9%). Discontinuation due to any adverse reaction occurred in 29% in the Kd arm versus 26% in the Vd arm. The most common reaction leading to discontinuation was cardiac failure in the Kd arm (n = 8, 2%) and peripheral neuropathy in the Vd arm (n = 22, 5%).

Adverse reactions in the first 6 months of therapy that occurred at a rate of 10% or greater in the Kd arm are presented in Table 10.

Table 10: Most Common Adverse Reactions (≥ 10% in the Kd Arm) Occurring in Months 1–6 (20/56 mg/m² Regimen In Combination with Dexamethasone)

The event rate of ≥ Grade 2 peripheral neuropathy in the Kd arm was 7% (95% CI: 5, 9) versus 35% (95% CI: 31, 39) in the Vd arm.

• Blood and lymphatic system disorders: febrile neutropenia, leukopenia, lymphopenia, neutropenia, thrombotic microangiopathy, thrombotic thrombocytopenic purpura

Table 11 describes Grades 3–4 laboratory abnormalities reported at a rate of ≥ 10% in the Kd arm.

Table 11: Grades 3–4 Laboratory Abnormalities (≥ 10%) in Months 1–6 (20/56 mg/m² Regimen In Combination with Dexamethasone)

The safety of Кипролис, dosed at 20/27 mg/m² by up to 10-minute infusion, was evaluated in clinical trials in which 598 patients with relapsed and/or refractory myeloma received Кипролис monotherapy starting with the 20 mg/m² dose in Cycle 1, Day 1 and escalating to 27 mg/m² on Cycle 1, Day 8 or Cycle 2, Day 1. Premedication with dexamethasone 4 mg was required before each dose in Cycle 1 and was optional for subsequent cycles. The median age was 64 years (range 32–87), and approximately 57% were male. The patients received a median of 5 (range 1–20) prior regimens. The median number of cycles initiated was 4 (range 1–35).

Serious adverse reactions, regardless of causality, were reported in 50% of patients in the pooled Кипролис monotherapy studies (N = 598). The most common serious adverse reactions were: pneumonia (8%), acute renal failure (5%), disease progression (4%), pyrexia (3%), hypercalcemia (3%), congestive heart failure (3%), multiple myeloma (3%), anemia (2%), and dyspnea (2%). In patients treated with Кипролис, the incidence of serious adverse reactions was higher in those ≥ 65 years old and those ≥ 75 years old.

Deaths due to adverse reactions within 30 days of the last dose of Кипролис occurred in 30/598 (5%) patients receiving Кипролис monotherapy. These adverse reactions were related to cardiac disorders in 10 (2%) patients, infections in 8 (1%) patients, renal disorders in 4 (< 1%) patients, and other adverse reactions in 8 (1%) patients. In a randomized trial comparing Кипролис as a single agent versus corticosteroids with optional oral cyclophosphamide for patients with relapsed and refractory multiple myeloma, mortality was higher in the patients treated with Кипролис in comparison to the control arm in the subgroup of 48 patients ≥ 75 years of age. The most common cause of discontinuation due to an adverse reaction was acute renal failure (2%).

Safety of Кипролис monotherapy dosed at 20/56 mg/m² by 30-minute infusion was evaluated in a multicenter, open-label study in patients with relapsed and/or refractory multiple myeloma. The study treatment is described in Section 14.3. The patients received a median of 4 (range 1–10) prior regimens.

The common adverse reactions occurring at a rate of 20% or greater with Кипролис monotherapy are presented in Table 12.

Table 12: Most Common Adverse Reactions (≥ 20%) with Кипролис Monotherapy

• Blood and lymphatic system disorders: febrile neutropenia, leukopenia, neutropenia

Therapeutic indications

• Кипролис is indicated in combination with dexamethasone or with lenalidomide plus dexamethasone for the treatment of patients with relapsed or refractory multiple myeloma who have received one to three lines of therapy.
• Кипролис is indicated as a single agent for the treatment of patients with relapsed or refractory multiple myeloma who have received one or more lines of therapy.

Pharmacodynamic properties

Intravenous carfilzomib administration resulted in suppression of proteasome chymotrypsin-like (CT-L) activity when measured in blood 1 hour after the first dose. Doses of carfilzomib ≥ 15 mg/m² with or without lenalidomide and dexamethasone induced a ≥ 80% inhibition of the CT-L activity of the proteasome. In addition, carfilzomib, 20 mg/m² intravenously as a single agent, resulted in a mean inhibition of the low molecular mass polypeptide 2 (LMP2) and multicatalytic endopeptidase complex-like 1 (MECL1) subunits of the proteasome ranging from 26% to 32% and 41% to 49%, respectively. Proteasome inhibition was maintained for ≥ 48 hours following the first dose of carfilzomib for each week of dosing.

Pharmacokinetic properties

The mean (CV%) Cmax and AUC following a 2- to 10-minute intravenous infusion of 27 mg/m² of carfilzomib were 4232 ng/mL (49%) and 379 ng•hr/mL (25%), respectively. Following repeated doses of carfilzomib at 15 and 20 mg/m², systemic exposure (AUC) and half-life were similar on Days 1 and 15 or 16 of Cycle 1, suggesting there was no systemic carfilzomib accumulation.

Following a 30-minute infusion of the 56 mg/m² dose, the mean (CV%) AUC of 948 ng•hr/mL (34%) was approximately twice that observed following a 2- to 10-minute infusion at the 27 mg/m² dose with a mean (CV%) of 379 ng•hr/mL (25%). The mean (CV%) Cmax of 2079 ng/mL (44%) following a 30-minute infusion of the 56 mg/m² dose was lower compared to that of 27 mg/m² over the 2- to 10-minute infusion with a mean (CV%) of 4232 ng/mL (49%).

At doses between 20 and 56 mg/m², there was a dose-dependent increase in exposure at either infusion duration.

The mean steady-state volume of distribution of a 20 mg/m² dose of carfilzomib was 28 L. When tested in vitro, the binding of carfilzomib to human plasma proteins averaged 97% over the concentration range of 0.4 to 4 micromolar.

Carfilzomib was rapidly and extensively metabolized. The predominant metabolites measured in human plasma and urine, and generated in vitro by human hepatocytes, were peptide fragments and the diol of carfilzomib, suggesting that peptidase cleavage and epoxide hydrolysis were the principal pathways of metabolism. Cytochrome P450-mediated mechanisms played a minor role in overall carfilzomib metabolism. The metabolites have no known biologic activity.

Following intravenous administration of doses ≥ 15 mg/m², carfilzomib was rapidly cleared from the systemic circulation with a half-life of ≤ 1 hour on Day 1 of Cycle 1. The systemic clearance ranged from 151 to 263 L/hour, and exceeded hepatic blood flow, suggesting that carfilzomib was largely cleared extrahepatically. In 24 hours, approximately 25% of the administered dose of carfilzomib was excreted in urine as metabolites. Urinary and fecal excretion of the parent compound was negligible (0.3% of total dose).

Special warnings and precautions for use

Included as part of the PRECAUTIONS section.

New onset or worsening of pre-existing cardiac failure (e.g., congestive heart failure, pulmonary edema, decreased ejection fraction), restrictive cardiomyopathy, myocardial ischemia, and myocardial infarction including fatalities have occurred following administration of Кипролис. Some events occurred in patients with normal baseline ventricular function. In clinical studies with Кипролис, these events occurred throughout the course of Кипролис therapy. Death due to cardiac arrest has occurred within one day of Кипролис administration. In a randomized, open-label, multicenter trial evaluating Кипролис in combination with lenalidomide and dexamethasone (KRd) versus lenalidomide/dexamethasone (Rd), the incidence of cardiac failure events was 6% in the KRd arm versus 4% in the Rd arm. In a randomized, open-label, multicenter trial of Кипролис plus dexamethasone (Kd) versus bortezomib plus dexamethasone (Vd), the incidence of cardiac failure events was 11% in the Kd arm versus 3% in the Vd arm.

Monitor patients for clinical signs or symptoms of cardiac failure or cardiac ischemia. Evaluate promptly if cardiac toxicity is suspected. Withhold Кипролис for Grade 3 or 4 cardiac adverse events until recovery, and consider whether to restart Кипролис at 1 dose level reduction based on a benefit/risk assessment.

While adequate hydration is required prior to each dose in Cycle 1, all patients should also be monitored 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.

In patients ≥ 75 years of age, the risk of cardiac failure is increased compared to patients < 75 years of age. Patients with New York Heart Association Class III and IV heart failure, recent myocardial infarction, conduction abnormalities, angina, or arrhythmias uncontrolled by medications were not eligible for the clinical trials. These patients may be at greater risk for cardiac complications and should have a comprehensive medical assessment (including blood pressure control and fluid management) prior to starting treatment with Кипролис and remain under close follow-up.

Cases of acute renal failure have occurred in patients receiving Кипролис. Some of these events have been fatal. Renal insufficiency adverse events (including renal failure) have occurred in approximately 10% of patients treated with Кипролис. Acute renal failure was reported more frequently in patients with advanced relapsed and refractory multiple myeloma who received Кипролис monotherapy. The risk of fatal renal failure was greater in patients with a baseline reduced estimated creatinine clearance (calculated using Cockcroft and Gault equation). Monitor renal function with regular measurement of the serum creatinine and/or estimated creatinine clearance. Reduce or withhold dose as appropriate.

Cases of tumor lysis syndrome (TLS), including fatal outcomes, have been reported in patients who received Кипролис. Patients with multiple myeloma and a high tumor burden should be considered to be at greater risk for TLS. Ensure that patients are well hydrated before administration of Кипролис in Cycle 1, and in subsequent cycles as needed. Consider uric acid-lowering drugs in patients at risk for TLS. Monitor for evidence of TLS during treatment and manage promptly, including interruption of Кипролис until TLS is resolved.

Acute Respiratory Distress Syndrome (ARDS), acute respiratory failure, and acute diffuse infiltrative pulmonary disease such as pneumonitis and interstitial lung disease have occurred in less than 1% of patients receiving Кипролис. Some events have been fatal. In the event of drug-induced pulmonary toxicity, discontinue Кипролис.

Pulmonary arterial hypertension was reported in approximately 1% of patients treated with Кипролис and was Grade 3 or greater in less than 1% of patients. Evaluate with cardiac imaging and/or other tests as indicated. Withhold Кипролис for pulmonary hypertension until resolved or returned to baseline, and consider whether to restart Кипролис based on a benefit/risk assessment.

Dyspnea was reported in 31% of patients treated with Кипролис and was Grade 3 or greater in 5% of patients. Evaluate dyspnea to exclude cardiopulmonary conditions including cardiac failure and pulmonary syndromes. Stop Кипролис for Grade 3 or 4 dyspnea until resolved or returned to baseline. Consider whether to restart Кипролис based on a benefit/risk assessment.

Hypertension, including hypertensive crisis and hypertensive emergency, has been observed with Кипролис. In a randomized, open-label, multicenter trial evaluating KRd versus Rd, the incidence of hypertension events was 16% in the KRd arm versus 8% in the Rd arm. In a randomized, open-label, multicenter trial of Kd versus Vd, the incidence of hypertension events was 34% in the Kd arm versus 11% in the Vd arm. Some of these events have been fatal. It is recommended to control hypertension prior to starting Кипролис. Monitor blood pressure regularly in all patients while on Кипролис. If hypertension cannot be adequately controlled, withhold Кипролис and evaluate. Consider whether to restart Кипролис based on a benefit/risk assessment.

Venous thromboembolic events (including deep venous thrombosis and pulmonary embolism) have been observed with Кипролис. In a randomized, open-label, multicenter trial evaluating KRd versus Rd (with thromboprophylaxis used in both arms), the incidence of venous thromboembolic events in the first 12 cycles was 13% in the KRd arm versus 6% in the Rd arm. In a randomized, open-label, multicenter trial of Kd versus Vd, the incidence of venous thromboembolic events in months 1–6 was 9% in the Kd arm versus 2% in the Vd arm. With Кипролис monotherapy, the incidence of venous thromboembolic events was 2%.

Thromboprophylaxis is recommended for patients being treated with the combination of Кипролис with dexamethasone or with lenalidomide plus dexamethasone. The thromboprophylaxis regimen should be based on an assessment of the patient's underlying risks.

Patients using oral contraceptives or a hormonal method of contraception associated with a risk of thrombosis should consider an alternative method of effective contraception during treatment with Кипролис in combination with dexamethasone or lenalidomide plus dexamethasone.

Infusion reactions, including life-threatening reactions, have occurred in patients receiving Кипролис. Symptoms include fever, chills, arthralgia, myalgia, facial flushing, facial edema, vomiting, weakness, shortness of breath, hypotension, syncope, chest tightness, or angina. These reactions can occur immediately following or up to 24 hours after administration of Кипролис. Administer dexamethasone prior to Кипролис to reduce the incidence and severity of infusion reactions. Inform patients of the risk and of symptoms and to contact a physician immediately if symptoms of an infusion reaction occur.

Fatal or serious cases of hemorrhage have been reported in patients treated with Кипролис. Hemorrhagic events have included gastrointestinal, pulmonary, and intracranial hemorrhage and epistaxis. The bleeding can be spontaneous, and intracranial hemorrhage has occurred without trauma. Hemorrhage has been reported in patients having either low or normal platelet counts. Hemorrhage has also been reported in patients who were not on antiplatelet therapy or anticoagulation. Promptly evaluate signs and symptoms of blood loss. Reduce or withhold dose as appropriate.

Кипролис causes thrombocytopenia with platelet nadirs observed between Day 8 and Day 15 of each 28-day cycle, with recovery to baseline platelet count usually by the start of the next cycle. Thrombocytopenia was reported in approximately 34% of patients in clinical trials with Кипролис. Monitor platelet counts frequently during treatment with Кипролис. Reduce or withhold dose as appropriate. Hemorrhage may occur.

Cases of hepatic failure, including fatal cases, have been reported (< 1%) during treatment with Кипролис. Кипролис can cause increased serum transaminases. Monitor liver enzymes regularly, regardless of baseline values. Reduce or withhold dose as appropriate.

Cases of thrombotic microangiopathy, including thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS), have been reported in patients who received Кипролис. Some of these events have been fatal. Monitor for signs and symptoms of TTP/HUS. If the diagnosis is suspected, stop Кипролис and evaluate. If the diagnosis of TTP/HUS is excluded, Кипролис may be restarted. The safety of reinitiating Кипролис therapy in patients previously experiencing TTP/HUS is not known.

Cases of posterior reversible encephalopathy syndrome (PRES) have been reported in patients receiving Кипролис. PRES, formerly termed Reversible Posterior Leukoencephalopathy Syndrome (RPLS), is a neurological disorder which can present with seizure, headache, lethargy, confusion, blindness, altered consciousness, and other visual and neurological disturbances, along with hypertension, and the diagnosis is confirmed by neuro-radiological imaging (MRI). Discontinue Кипролис if PRES is suspected and evaluate. The safety of reinitiating Кипролис therapy in patients previously experiencing PRES is not known.

In a clinical trial of 955 transplant-ineligible patients with newly diagnosed multiple myeloma randomized to Кипролис (20/36 mg/m² by 30-minute infusion twice weekly for four of each six-week cycle), melphalan and prednisone (KMP) or bortezomib, melphalan and prednisone (VMP), a higher incidence of fatal adverse reactions (7% versus 4%) and serious adverse reactions (50% versus 42%) were observed in the KMP arm compared to patients in the VMP arm, respectively. Patients in the KMP arm were observed to have a higher incidence of any grade adverse reactions involving cardiac failure (11% versus 4%), hypertension (25% versus 8%), acute renal failure (14% versus 6%), and dyspnea (18% versus 9%). This study did not meet its primary outcome measure of superiority in progression-free survival for the KMP arm. Кипролис in combination with melphalan and prednisone is not indicated for transplant-ineligible patients with newly diagnosed multiple myeloma.

Кипролис can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals. There are no adequate and well-controlled studies in pregnant women using Кипролис.

Advise females of reproductive potential to avoid becoming pregnant while being treated with Кипролис. Advise males of reproductive potential to avoid fathering a child while being treated with Кипролис. Advise women who use Кипролис during pregnancy or become pregnant during treatment with Кипролис of the potential hazard to the fetus.

Carcinogenicity studies have not been conducted with carfilzomib.

Carfilzomib was clastogenic in the in vitro chromosomal aberration test in peripheral blood lymphocytes. Carfilzomib was not mutagenic in the in vitro bacterial reverse mutation (Ames) test and was not clastogenic in the in vivo mouse bone marrow micronucleus assay.

Fertility studies with carfilzomib have not been conducted. No effects on reproductive tissues were noted during 28-day repeat-dose rat and monkey toxicity studies or in 6-month rat and 9-month monkey chronic toxicity studies.

Кипролис can cause fetal harm based on findings from animal studies and the drug's mechanism of action. There are no adequate and well-controlled studies in pregnant women using Кипролис.

Females of reproductive potential should be advised to avoid becoming pregnant while being treated with Кипролис. Males of reproductive potential should be advised to avoid fathering a child while being treated with Кипролис. Consider the benefits and risks of Кипролис and possible risks to the fetus when prescribing Кипролис to a pregnant woman. If Кипролис is used during pregnancy, or if the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard 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.

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. Carfilzomib was not teratogenic at any dose tested. 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/m² based on body surface area.

There is no information regarding the presence of Кипролис in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Кипролис and any potential adverse effects on the breastfed infant from Кипролис or from the underlying maternal condition.

Кипролис can cause fetal harm. Advise female patients of reproductive potential to use effective contraceptive measures or abstain from sexual activity to prevent pregnancy during treatment with Кипролис and for at least 30 days following completion of therapy. Advise male patients of reproductive potential to use effective contraceptive measures or abstain from sexual activity to prevent pregnancy during treatment with Кипролис and for at least 90 days following completion of therapy.

The safety and effectiveness of Кипролис in pediatric patients have not been established.

Of 598 patients in clinical studies of Кипролис monotherapy dosed at 20/27 mg/m² by up to 10-minute infusion, 49% were 65 and over, while 16% were 75 and over. The incidence of serious adverse events was 44% in patients < 65 years of age, 55% in patients 65 to 74 years of age, and 56% in patients ≥ 75 years of age. In a single-arm, multicenter clinical trial of Кипролис monotherapy dosed at 20/27 mg/m² (N = 266), no overall differences in effectiveness were observed between older and younger patients.

Of 392 patients treated with Кипролис in combination with lenalidomide and dexamethasone, 47% were 65 and over and 11% were 75 years and over. The incidence of serious adverse events was 50% in patients < 65 years of age, 70% in patients 65 to 74 years of age, and 74% in patients ≥ 75 years of age. No overall differences in effectiveness were observed between older and younger patients.

Of 463 patients treated with Кипролис dosed at 20/56 mg/m² by 30-minute infusion in combination with dexamethasone, 52% were 65 and over and 17% were 75 and over. The incidence of serious adverse events was 54% in patients < 65 years of age, 60% in patients 65 to 74 years of age, and 70% in patients ≥ 75 years of age. No overall differences in effectiveness were observed between older and younger patients.

Reduce the dose of Кипролис by 25% in patients with mild or moderate hepatic impairment. Dosing recommendation cannot be made for patients with severe hepatic function.

The pharmacokinetics and safety of Кипролис were evaluated in patients with advanced malignancies who had either normal hepatic function, or mild (bilirubin > 1 to 1.5 × ULN or AST > ULN), moderate (bilirubin > 1.5 to 3 × ULN), or severe (bilirubin > 3 × ULN) hepatic impairment. The AUC of carfilzomib increased by approximately 50% in patients with mild and moderate hepatic impairment compared to patients with normal hepatic function. PK data were not collected in patients with severe hepatic impairment. The incidence of serious adverse events was higher in patients with mild, moderate, and severe hepatic impairment combined (22/35 or 63%) than in patients with normal hepatic function (3/11 or 27%).

Monitor liver enzymes regularly, regardless of baseline values, and modify dose based on toxicity.

No starting dose adjustment is required in patients with baseline mild, moderate, or severe renal impairment or patients on chronic hemodialysis. The pharmacokinetics and safety of Кипролис were evaluated in a Phase 2 trial in patients with normal renal function and those with mild, moderate, and severe renal impairment and patients on chronic hemodialysis. In addition, a pharmacokinetic study was conducted in patients with normal renal function and end-stage renal disease (ESRD).

In these studies, the pharmacokinetics of Кипролис was not influenced by the degree of baseline renal impairment, including the patients on hemodialysis. Since dialysis clearance of Кипролис concentrations has not been studied, the drug should be administered after the hemodialysis procedure.

Dosage (Posology) and method of administration

Adequate hydration is required prior to dosing in Cycle 1, especially in patients at high risk of tumor lysis syndrome or renal toxicity. The recommended hydration includes 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 Кипролис 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.

Monitor serum potassium levels regularly during treatment with Кипролис.

Premedicate with the recommended dose of dexamethasone fo  monotherapy or the recommended dexamethasone dose if on combination therapy. Administer dexamethasone orally or intravenously at least 30 minutes but no more than 4 hours prior to all doses of Кипролис during Cycle 1 to reduce the incidence and severity of infusion reactions. Reinstate dexamethasone premedication if these symptoms occur during subsequent cycles.

Кипролис can be administered in a 50 mL or 100 mL intravenous bag of 5% Dextrose Injection, USP. Infuse over 10 or 30 minutes depending on the Кипролис dose regimen. Do not administer as a bolus. Flush the intravenous administration line with normal saline or 5% dextrose injection, USP immediately before and after Кипролис administration. Do not mix Кипролис with or administer as an infusion with other medicinal products.

Calculate the Кипролис dose using the patient's actual body surface area at baseline. In patients with a body surface area greater than 2.2 m², calculate the dose based upon a body surface area of 2.2 m².

Thromboprophylaxis is recommended for patients being treated with the combination of Кипролис with dexamethasone or with lenalidomide plus dexamethasone. The thromboprophylaxis regimen should be based on an assessment of the patient's underlying risks.

Consider antiviral prophylaxis for patients being treated with Кипролис to decrease the risk of herpes zoster reactivation.

Administer Кипролис after the hemodialysis procedure.

For the combination regimen with lenalidomide and dexamethasone, administer Кипролис intravenously as a 10-minute infusion on two consecutive days, each week for three weeks followed by a 12-day rest period as shown in Table 1. Each 28-day period is considered one treatment cycle. The recommended starting dose of Кипролис is 20 mg/m² in Cycle 1 on Days 1 and 2. If tolerated, escalate the dose to 27 mg/m² on Day 8 of Cycle 1. From Cycle 13, omit the Day 8 and 9 doses of Кипролис. Discontinue Кипролис after Cycle 18. Lenalidomide 25 mg is taken orally on Days 1–21 and dexamethasone 40 mg by mouth or intravenously on Days 1, 8, 15, and 22 of the 28-day cycles.

Table 1: Кипролис (10-Minute Infusion) in Combination with Lenalidomide and Dexamethasone

Continue treatment until disease progression or unacceptable toxicity occurs. Refer to the lenalidomide and dexamethasone Prescribing Information for other concomitant medications, such as the use of anticoagulant and antacid prophylaxis, that may be required with those agents.

For the combination regimen with dexamethasone, administer Кипролис intravenously as a 30-minute infusion on two consecutive days, each week for three weeks followed by a 12-day rest period as shown in Table 2. Each 28-day period is considered one treatment cycle. Administer Кипролис by 30-minute infusion at a starting dose of 20 mg/m² in Cycle 1 on Days 1 and 2. If tolerated, escalate the dose to 56 mg/m² on Day 8 of Cycle 1. Dexamethasone 20 mg is taken by mouth or intravenously on Days 1, 2, 8, 9, 15, 16, 22, and 23 of each 28-day cycle. Administer dexamethasone 30 minutes to 4 hours before Кипролис.

Table 2: Кипролис (30-Minute Infusion) in Combination with Dexamethasone

Treatment may be continued until disease progression or unacceptable toxicity occurs. Refer to the dexamethasone Prescribing Information for other concomitant medications.

For monotherapy, administer Кипролис intravenously as a 10-minute or 30-minute infusion depending on the regimen as described below.

20/27 mg/m² Regimen By 10-Minute Infusion

For monotherapy using the 20/27 mg/m² regimen, administer Кипролис intravenously as a 10-minute infusion. In Cycles 1 through 12, administer Кипролис on two consecutive days, each week for three weeks followed by a 12-day rest period as shown in Table 3. Each 28-day period is considered one treatment cycle. From Cycle 13, omit the Day 8 and 9 doses of Кипролис (see Table 3). Premedicate with dexamethasone 4 mg orally or intravenously 30 minutes to 4 hours before each Кипролис dose in Cycle 1, then as needed to help prevent infusion reactions. The recommended starting dose of Кипролис is 20 mg/m² in Cycle 1 on Days 1 and 2. If tolerated, escalate the dose to 27 mg/m² on Day 8 of Cycle 1. Treatment may continue until disease progression or unacceptable toxicity occurs.

Modify dosing based on toxicity. Recommended actions and dose modifications for Кипролис are presented in Table 5. Dose level reductions are presented in Table 6. See the lenalidomide and dexamethasone Prescribing Information respectively for dosing recommendations.

Table 5: Dose Modifications for Toxicitya during Кипролис Treatment

Table 6: Dose Level Reductions for Кипролис

For patients with mild or moderate hepatic impairment, reduce the dose of Кипролис by 25%. Dosing recommendation cannot be made in patients with severe hepatic impairment.

For patients with end stage renal disease who are on dialysis, administer Кипролис after the hemodialysis procedure.

Кипролис vials contain no antimicrobial preservatives and are intended for single use only. Unopened vials of Кипролис are stable until the date indicated on the package when stored in the original package at 2°C to 8°C (36°F to 46°F). The reconstituted solution contains carfilzomib at a concentration of 2 mg/mL.

Read the complete preparation instructions prior to reconstitution. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

1. Remove vial from refrigerator just prior to use.
2. Calculate the dose (mg/m²) and number of vials of Кипролис required using the patient's body surface area (BSA) at baseline. Patients with a BSA greater than 2.2 m² should receive a dose based upon a BSA of 2.2 m². Dose adjustments do not need to be made for weight changes of less than or equal to 20%.
3. Use a 21-gauge or larger gauge needle (0.8 mm or smaller external diameter needle) to aseptically reconstitute each vial by slowly injecting 29 mL (for 60 mg vial) or 15 mL (for 30 mg vial) Sterile Water for Injection, USP, through the stopper and directing the solution onto the INSIDE WALL OF THE VIAL to minimize foaming.
4. Gently swirl and/or invert the vial slowly for about 1 minute, or until complete dissolution. DO NOT SHAKE to avoid foam generation. If foaming occurs, allow the solution to settle in the vial until foaming subsides (approximately 5 minutes) and the solution is clear.
5. Visually inspect for particulate matter and discoloration prior to administration. The reconstituted product should be a clear, colorless solution and should not be administered if any discoloration or particulate matter is observed.
6. Discard any unused portion left in the vial. DO NOT pool unused portions from the vials. DO NOT administer more than one dose from a vial.
7. Кипролис can be administered directly by intravenous infusion or optionally, administered in a 50 mL to 100 mL intravenous bag containing 5% Dextrose Injection, USP. Do not administer as an intravenous push or bolus.
8. When administering in an intravenous bag, use a 21-gauge or larger gauge needle (0.8 mm or smaller external diameter needle) to withdraw the calculated dose from the vial and dilute into 50 mL or 100 mL intravenous bag containing 5% Dextrose Injection, USP (based on the calculated total dose and infusion time).

The stabilities of reconstituted Кипролис under various temperature and container conditions are shown in Table 7.
