There were 274 ( 70 %) patients in the KRd arm who received treatment beyond Cycle 12 . There were no new clinically relevant adverse reactions that emerged in the later treatment cycles .
Grade 3 and higher adverse reactions that occurred during Cycles 1 – 12 with a substantial difference ( ≥ 2 %) between the two arms were neutropenia , thrombocytopenia , hypokalemia , and hypophosphatemia .
Safety Experience with Kyprolis in Combination with Dexamethasone in Patients with Multiple Myeloma
The safety of Kyprolis in combination with dexamethasone was evaluated in an open-label , randomized trial of patients with relapsed multiple myeloma . Patients received treatment for a median duration of 40 weeks in the Kyprolis / 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 22 / 463 ( 5 %) 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 vs . Vd ) included cardiac 7 ( 2 %) versus 5 ( 1 %), infections 5 ( 1 %) versus 8 ( 2 %), disease progression 6 ( 1 %) versus 4 ( 1 %), pulmonary 3 ( 1 %) versus 2 (< 1 %), renal 1 (< 1 %) versus 0 ( 0 %), and other adverse events 2 (< 1 %) versus 2 (< 1 %). Serious adverse reactions were reported in 48 % of the patients in the Kd arm and 36 % of the patients in the Vd arm . In both treatment arms , pneumonia was the most commonly reported serious adverse reaction ( 6 % vs . 9 %). Discontinuation due to any adverse reaction occurred in 20 % in the Kd arm versus 21 % in the Vd arm . The most common reaction leading to discontinuation was cardiac failure in the Kd arm ( n = 6 , 1.3 %) and peripheral neuropathy in the Vd arm ( n = 19 , 4.2 %).
Most Common Adverse Reactions ( ≥ 10 % in the Kd Arm ) Occurring in Months 1 – 6 ( 20 / 56 mg / m 2 Regimen in Combination with Dexamethasone )

The event rate of ≥ Grade 2 peripheral neuropathy in the Kd arm was 6 % ( 95 % CI : 4 , 8 ) versus 32 % ( 95 % CI : 28 , 36 ) in the Vd arm .
6.2 Postmarketing Experience The following additional adverse reactions were reported in the postmarketing experience with Kyprolis . Because these reactions are reported voluntarily from a population of uncertain size , it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure : hemolytic uremic syndrome ( HUS ), gastrointestinal perforation , pericarditis .
8 . USE IN SPECIFIC POPULATIONS
8.1 Pregnancy Risk Summary
Kyprolis 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 Kyprolis .
Females of reproductive potential should be advised to avoid becoming pregnant while being treated with Kyprolis . Males of reproductive potential should be advised to avoid fathering a child while being treated with Kyprolis . Consider the benefits and risks of Kyprolis and possible risks to the fetus when prescribing Kyprolis to a pregnant woman . If Kyprolis 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 .
8.2 Lactation Risk Summary
There is no information regarding the presence of Kyprolis 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 Kyprolis and any potential adverse effects on the breastfed infant from Kyprolis or from the underlying maternal condition .
8.3 Females and Males of Reproductive Potential Contraception
Kyprolis 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 Kyprolis 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 Kyprolis and for at least 90 days following completion of therapy .
8.4 Pediatric Use The safety and effectiveness of Kyprolis in pediatric patients have not been established .
8.5 Geriatric Use Of 598 patients in clinical studies of Kyprolis monotherapy dosed at 20 / 27 mg / m 2 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 Kyprolis monotherapy dosed at 20 / 27 mg / m 2 ( N = 266 ), no overall differences in effectiveness were observed between older and younger patients .
Of 392 patients treated with Kyprolis 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 Kyprolis dosed at 20 / 56 mg / m 2 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 44 % in patients < 65 years of age , 50 % in patients 65 to 74 years of age , and 57 % in patients ≥ 75 years of age . No overall differences in effectiveness were observed between older and younger patients .
8.6 Hepatic Impairment Reduce the dose of Kyprolis 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 Kyprolis 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 .
8.7 Renal Impairment 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 Kyprolis 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 Kyprolis was not influenced by the degree of baseline renal impairment , including the patients on hemodialysis . Since dialysis clearance of Kyprolis concentrations has not been studied , the drug should be administered after the hemodialysis procedure .
