Dose Modifications To Be Made During Treatment Cycles of Combination Velcade, Melphalan, and Prednisone Therapy



Toxicity

Dose modification or delay

If prolonged very serious (Grade 4) neutropenia or thrombocytopenia is experienced during a cycle, or thrombocytopenia with bleeding is observed in the previous cycle

Consider reduction of the melphalan dose by 25% in the next cycle

If platelet count is =30 x 109/L or absolute neutrophil count (ANC) is =0.75 x 109/L on a Velcade dosing day (other than day 1)

Velcade dose should be withheld

If several Velcade doses in consecutive cycles are withheld due to toxicity

Velcade dose should be reduced by one dose level (from 1.3 mg/m2 to 1 mg/m2, or from 1 mg/m2 to 0.7 mg/m2)

Serious (Grade 3) or higher non-hematological toxicities

Velcade therapy should be withheld until symptoms of the toxicity have resolved to Grade 1 or baseline. Then, Velcade may be restarted with one dose level reduction (from 1.3 mg/m2 to 1 mg/m2, or from 1 mg/m2 to 0.7 mg/m2).

For Velcade-related neuropathic pain and/or peripheral neuropathy, hold or modify Velcade as outlined here.





Recommended Dose Modifications for Velcade-related Neuropathic Pain and/or Peripheral Sensory or Motor Neuropathy



Severity of Peripheral Neuropathy Signs and Symptoms

Modification of Dose and Regimen

Grade 1* (paresthesias [sensations of numbness, tingling, or prickling], weakness, and/or loss of reflexes) without pain or loss of function

No action

Grade 1 with pain or Grade 2 (interfering with function but not with activities of daily living)

Reduce Velcade dose to 1.0 mg/m2

Grade 2 with pain or Grade 3 (interfering with activities of daily living)

Withhold Velcade therapy until toxicity resolves. When toxicity resolves, reinitiate with a reduced dose of Velcade at 0.7 mg/m2 and change treatment schedule to once per week.

Grade 4 (permanent sensory loss that interferes with function, sensory neuropathy which is disabling, or motor neuropathy that is life threatening or leads to paralysis)

Discontinue Velcade





Recommended Starting Dose Modification for Velcade in Patients with Hepatic Impairment


This chart shows how the starting dose of Velcade should be modified in patients with liver (hepatic) impairment.



Level of impairment*

Bilirubin level

SGOT (AST) level

Modification of Velcade starting dose  

Mild

≤ 1.0 x ULN

> ULN

None Needed

> 1.0 x – 1.5 x ULN

Any

None Needed

Moderate

> 1.5 x – 3.0 x ULN

Any

First cycle: Reduce Velcade to 0.7 mg/m2 Subsequent cycles: Consider raising dose to 1.0 mg/m2 if tolerated well, or reducing dose further if necessary

Severe

> 3.0 x ULN

Any


Abbreviations: AST = aspartate aminotransferase; SGOT = serum glutamic oxaloacetic transaminase; ULN = upper limit of the normal range.

*Liver impairment is noted by increased levels of certain substances that can be measured in the blood. These include bilirubin, a breakdown product of red blood cells that is normally removed by the liver, and the liver enzyme SGOT, which is also called AST.
