Most Common Adverse Reactions (≥ 10% in the KRd Arm)
Occurring in Cycles 1–12 (20/27 mg/m 2 Regimen in Combination

Safety Experience with Kyprolis in Combination with Dexamethasone in Patients with Multiple Myeloma
The safety of Kyprolis in combination with dexamethasone was evaluated in two open-label, randomized
trials (ENDEAVOR and A.R.R.O.W.).
ENDEAVOR evaluated patients with relapsed or refractory multiple myeloma. Patients received treatment for
a median duration of 48 weeks in the twice weekly Kyprolis/dexamethasone (Kd) 20/56 mg/m 2 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 vs. 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% vs. 9%). In patients treated with Kyprolis, 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 69% in patients ≥ 75 years of age.
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%). The incidence of cardiac failure events was 11% in the
Kd arm versus 3% in the Vd arm.
