Kyprolis Dosage

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 m2 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 m2, calculate the Kyprolis dose using a BSA of 2.2 m2.

​Once Weekly 20/70 mg/m2 (30-minute infusion)

​Kyprolis once weekly 20/70 mg/m2 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/m2 on Cycle 1, Day 1. If tolerated, escalate the dose to 70 mg/m2 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.

​Twice Weekly 20/56 mg/m2 (30-minute infusion)

​Kyprolis twice weekly 20/56 mg/m2 administered as monotherapy or in combination with

• ​dexamethasone (Kd),
• ​daratumumab plus dexamethasone (DKd),
• ​daratumumab and hyaluronidase-fihj plus dexamethasone (DKd), or
• ​isatuximab plus dexamethasone (Isa-Kd).

​The recommended starting dosage of Kyprolis is 20 mg/m2 on Cycle 1, Days 1 and 2. If tolerated, escalate the dose to 56 mg/m2 on Cycle 1, Day 8. Administer Kyprolis intravenously as a 30-minute infusion on Days 1, 2, 8, 9, 15, and 16 of each 28-day cycle as shown in Table 2 until disease progression or unacceptable toxicity [see Clinical Studies (Section 14)]. If given as monotherapy, administer 8 mg dexamethasone orally or intravenously 30 minutes to 4 hours before Kyprolis then as needed to minimize infusion-related reactions [see Dosage and Administration (2.1)]. Kyprolis given as monotherapy may be omitted on Days 8 and 9 of cycle 13 onward. For dosage instructions of combination agents administered with Kyprolis, see Clinical Studies sections 14.2 (Kd), 14.3 (DKd), 14.4 (Isa-Kd), and 14.5 (Monotherapy). Refer to the Prescribing Information for dexamethasone, intravenous daratumumab, subcutaneous daratumumab and hyaluronidase-fihj, and isatuximab for additional dosage information.

​ Twice Weekly 20/27 mg/m2 (10-minute infusion)

​Kyprolis twice weekly 20/27mg/m2 is administered as monotherapy or in combination with lenalidomide and dexamethasone (KRd).

​The recommended starting dosage of Kyprolis 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 and thereafter. Administer Kyprolis intravenously as a 10-minute infusion [see Clinical Studies (14.4)]. In Cycles 1 through 12, administer Kyprolis on Days 1, 2, 8, 9, 15 and 16 of each 28-day cycle as shown in Table 3. From Cycle 13, administer Kyprolis on Days 1, 2, 15 and 16 of each 28-day cycle. If given as monotherapy, premedicate with dexamethasone 4 mg orally or intravenously 30 minutes to 4 hours before each Kyprolis dose in Cycle 1, then as needed to minimize infusion-related reactions [see Dosage and Administration (2.1)]. Continue Kyprolis with the regimens shown in Table 3 until disease progression or unacceptable toxicity occurs. When combined with lenalidomide and dexamethasone, discontinue Kyprolis after Cycle 18 and continue lenalidomide and dexamethasone until disease progression or unacceptable toxicity occurs. For dosage instructions of combination agents with Kyprolis, see Clinical Studies sections 14.1 (KRd) and 14.5 (Monotherapy). Refer to the Prescribing Information for dexamethasone and lenalidomide for additional dosage information.

Reconstitution/Preparation Steps:

1. Remove vial from refrigerator just prior to use.
2. Calculate the dose (mg/m2) and number of vials of Kyprolis required using the patient's BSA at baseline.
3. Aseptically reconstitute each Kyprolis vial only with Sterile Water for Injection, USP using the volumes described in Table 6. Use a 21-gauge or larger needle (0.8 mm or smaller external diameter needle) to reconstitute each vial by slowly injecting Sterile Water for Injection, USP through the stopper and directing the Sterile Water for Injection, USP onto the INSIDE WALL OF THE VIAL to minimize foaming. There is no data to support the use of closed system transfer devices with Kyprolis.
   

   

   Table 6: Reconstitution Volumes

   Strength	Amount of Sterile Water for Injection, USP required for reconstitution
   10 mg vial	5 mL
   30 mg vial	15 mL
   60 mg vial	29 mL

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. Administer Kyprolis directly by intravenous infusion or 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 only 5% Dextrose Injection, USP (based on the calculated total dose and infusion time).
9. Flush the intravenous administration line with normal saline or 5% Dextrose Injection, USP immediately before and after Kyprolis administration.
10. Do not mix Kyprolis with or administer as an infusion with other medicinal products.

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