A - Regimen Name

CARF Regimen

Disease Site
Hematologic - Multiple Myeloma


Regimen Category
Evidence-Informed :

Regimen is considered appropriate as part of the standard care of patients; meaningfully improves outcomes (survival, quality of life), tolerability or costs compared to alternatives (recommended by the Disease Site Team and national consensus body e.g. pan-Canadian Oncology Drug Review, pCODR).  Recommendation is based on an appropriately conducted phase III clinical trial relevant to the Canadian context OR (where phase III trials are not feasible) an appropriately sized phase II trial. Regimens where one or more drugs are not approved by Health Canada for any indication will be identified under Rationale and Use.

Rationale and Uses

For the treatment of relapsed or refractory multiple myeloma in patients who have received two or more prior therapies for relapsed disease.

B - Drug Regimen

Cycle 1:

20 mg /m² IV Days 1, 2, 8, 9, 15, 16
(This drug is not currently publicly funded for this regimen and intent)


Cycles 2-12:



27 mg /m² IV Days 1, 2, 8, 9, 15, 16
(This drug is not currently publicly funded for this regimen and intent)

1 If cycle 1 at the initial dose level of 20 mg/m2 was well tolerated, the dose was escalated to 27 mg/m2 for all subsequent cycles

C - Cycle Frequency


Until disease progression or unacceptable toxicity.

D - Premedication and Supportive Measures

Antiemetic Regimen:


Other Supportive Care:

Also refer to CCO Antiemetic Summary


  • Consider the use of antiviral prophylaxis during carfilzomib therapy to decrease the risk of herpes zoster reactivation.

  • Thromboprophylaxis is recommended in patients being treated with carfilzomib in combination with dexamethasone. The choice of agent should be based on patient risk factors and clinical status.

  • Hypertension should be well-controlled prior to initiation of treatment with carfilzomib.

  • Adequate hydration is required prior to dosing in cycle 1, especially in patients at high risk for tumour lysis syndrome or renal toxicity. The total fluid volume may be adjusted as clinically indicated in patients with baseline or at high risk of cardiac failure.

  • Cycle 1:

    • oral fluids (30 mL/kg/day for 48 hours before start of cycle)

    • 250-500 mL of IV fluid before and after each dose (if needed)

  • Subsequent cycles:

    • continue oral and/or IV hydration as needed

  • Dexamethasone IV/PO should be given at least 30 minutes, but no more than 4 hours before carfilzomib.

E - Dose Modifications

Doses should be modified according to the protocol by which the patient is being treated.

Patients with BSA > 2.2 m2 should be dosed based on a maximum BSA of 2.2 m2. Dose adjustments for carfilzomib do not need to be made for weight changes ≤ 20%.

Refer to carfilzomib drug monograph for additional details on dose modifications.

Dosage with toxicity

Dose levels

Dose level

Carfilzomib (mg/m2)










Dose Modifications for Hematological and Non-Hematological Toxicities:


Carfilzomib Dose


ANC < 0.5 x 109/L, febrile neutropenia or platelets < 10 x 109/L ; thrombocytopenic bleeding

1st instance: hold until recovery* (and/or bleeding is controlled, fever resolves), and then restart at the same dose level.

Subsequent instances: hold until recovery* (and/or bleeding is controlled); consider restarting at 1 dose level ↓.

Increased creatinine

SCr ≥ 2 x baseline, or CrCl < 15 mL/min (or CrCl decreases to ≤ 50% of baseline) or need for dialysis


  • If attributable to carfilzomib, resume at 1 dose level ↓ when renal function has recovered to within 25% of baseline.

  • If not attributable to carfilzomib, may resume at physician's discretion.

If tolerated, the reduced dose may be increased to the previous dose.

Grade 3 or 4 cardiac events

Hold until resolved. Consider risk vs. benefit of restarting; resume at 1 dose level ↓.

Hypertensive crisis/emergency

Hold until resolves or under control.

Consider the risk vs. benefit of restarting; consider restarting at 1 dose level ↓.

ARDS, ILD, pneumonitis, pulmonary hypertension, grade 3 or 4 dyspnea Hold until resolves. Consider the risk vs. benefit of restarting.
Thrombotic microangiopathy (including TTP/HUS) Hold and evaluate. Discontinue if confirmed.
PRES Hold and evaluate. Discontinue if confirmed.
All other Grade 3 or 4 non-hematological toxicities Hold until resolved or at baseline. After resolution, if appropriate to reinitiate, consider restarting at 1 dose level ↓.

*Do not retreat until ANC ≥ 0.5 x 109/L (or baseline values for febrile neutropenia) and platelets ≥ 10 x 109/L with resolution of fever and bleeding

Hepatic Impairment

In a pharmacokinetic study, carfilzomib AUC increased by 50% in patients with baseline mild or moderate hepatic impairment compared to those with normal hepatic function. The incidence of serious adverse events was higher in patients with hepatic impairment as well.


Carfilzomib Starting Dose

Mild ( bilirubin > 1-1.5 x ULN or AST > ULN) or moderate (bilirubin > 1.5-3 x ULN)

Reduce dose by 25%

Severe (bilirubin > 3 x ULN)

No data

Renal Impairment

No dose adjustment is required for carfilzomib in patients with baseline renal impairment. For patients on dialysis receiving carfilzomib, administer dose after dialysis.

Dosage in the Elderly

There was a higher incidence of certain adverse effects (including cardiac failure) observed in patients ≥ 65 years of age, especially those more than 75 years, when carfilzomib was given in combination with lenalidomide and dexamethasone.

G - Interactions

Refer to carfilzomib drug monograph(s) for additional details

  • It is unknown whether carfilzomib is an inducer of CYP1A2, 2C8, 2C9, 2C19 and 2B6. Caution should be observed when combined with products which are substrates of these enzymes, including oral contraceptives.

  • Carfilzomib does not induce, but may inhibit, CYP3A4/5.

  • Caution with P-glycoprotein substrates (i.e. verapamil, digoxin, morphine, ondansetron) and monitor digoxin levels.

  • Caution and consider non-hormonal method(s) of contraception as use of oral contraceptives or other hormonal methods of contraception may have reduced efficacy and may increase the risk of blood clots.

H - Drug Administration and Special Precautions

Refer to carfilzomib drug monograph(s) for additional details


  • Carfilzomib should be given as a 10 minute infusion
  • May further dilute dose in 50-100 mL D5W. Do not dilute in NS for IV administration.

  • Carfilzomib should not be administered as an IV bolus. Maybe administered directly by IV infusion or in an IV bag.

  • Flush line before and after carfilzomib administration with NS or D5W.

  • After reconstitution, gently swirl and/or invert the vial slowly for 1 minute. Do not shake.

  • If foaming occurs, allow the solution to settle in the vial until foaming subsides (approximately 5 minutes) and the solution is clear, colourless and free of visible particulates.

  • Stable in D5W. Do not mix with or administer as an infusion with other medications.

  • The time from reconstitution to administration should not exceed 24 hours.

  • Unreconstituted carfilzomib powder for injection should be stored in unopened vials at 2–8°C.



  • Patients who have a hypersensitivity to these drugs or any of their components

Other Warnings/Precautions:

  • Use carfilzomib with caution in patients on a controlled sodium diet. Each mL contains 0.3 mmols (7 mg) of sodium.

  • The risk of heart failure is increased in elderly patients (≥ 75 years).  Patients with NYHA Class III/IV heart failure, recent MI, conduction abnormalities, angina or arrhythmias uncontrolled by medications were not eligible for carfilzomib-based clinical trials.  These patients may be at greater risk of cardiac complications and should have their medical management optimized, including hypertension, prior to starting treatment with carfilzomib and monitored closely throughout.

  • Use caution with driving or using machinery as fatigue, dizziness and a drop in blood pressure may occur with carfilzomib treatment.


Pregnancy and Lactation:

  • Carfilzomib is not recommended for use in pregnancy.

    • Adequate contraception should be used by female patients and/or their male partners during carfilzomib treatment, and for 30 days after the last dose.

    • Adequate contraception should be used by male patients and/or their female partners during carfilzomib treatment, and for 90 days after the last dose.

  • Breastfeeding is not recommended .

  • Fertility effects: no information available.

I - Recommended Clinical Monitoring

Suggested Clinical Monitoring

  • Blood glucose levels; Baseline and regular

  • ECG; Baseline; repeat if arrhythmia suspected
