"Nov. 20, 2012 -- Although mammograms remain the gold standard for breast cancer screening, they are not the perfect test.
They don't find up to 30% of cancers, and they often find something that may be suspicious for cancer but really"...
PERJETA is indicated for use in combination with trastuzumab and docetaxel for the treatment of patients with HER2-positive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease.
DOSAGE AND ADMINISTRATION
Recommended Doses and Schedules
The initial dose of PERJETA is 840 mg administered as a 60-minute intravenous infusion, followed every 3 weeks thereafter by a dose of 420 mg administered as an intravenous infusion over 30 to 60 minutes.
When administered with PERJETA, the recommended initial dose of trastuzumab is 8 mg/kg administered as a 90-minute intravenous infusion, followed every 3 weeks thereafter by a dose of 6 mg/kg administered as an intravenous infusion over 30 to 90 minutes.
When administered with PERJETA, the recommended initial dose of docetaxel is 75 mg/m² administered as an intravenous infusion. The dose may be escalated to 100 mg/m² administered every 3 weeks if the initial dose is well tolerated.
For delayed or missed doses, if the time between two sequential infusions is less than 6 weeks, the 420 mg dose of PERJETA should be administered. Do not wait until the next planned dose. If the time between two sequential infusions is 6 weeks or more, the initial dose of 840 mg PERJETA should be re-administered as a 60-minute intravenous infusion followed every 3 weeks thereafter by a dose of 420 mg administered as an intravenous infusion over 30 to 60 minutes.
The infusion rate of PERJETA may be slowed or interrupted if the patient develops an infusion-associated reaction. The infusion should be discontinued immediately if the patient experiences a serious hypersensitivity reaction [see WARNINGS AND PRECAUTIONS].
Left Ventricular Ejection Fraction (LVEF)
Withhold PERJETA and trastuzumab dosing for at least 3 weeks for either:
- a drop in LVEF to less than 40% or
- LVEF of 40% to 45% with a 10% or greater absolute decrease below pretreatment values [see WARNINGS AND PRECAUTIONS]
PERJETA may be resumed if the LVEF has recovered to greater than 45% or to 40% to 45% associated with less than a 10% absolute decrease below pretreatment values.
If after a repeat assessment within approximately 3 weeks, the LVEF has not improved, or has declined further, discontinuation of PERJETA and trastuzumab should be strongly considered, unless the benefits for the individual patient are deemed to outweigh the risks [see WARNINGS AND PRECAUTIONS].
PERJETA should be withheld or discontinued if trastuzumab treatment is withheld or discontinued.
If docetaxel is discontinued, treatment with PERJETA and trastuzumab may continue.
Dose reductions are not recommended for PERJETA.
For docetaxel dose modifications, see docetaxel prescribing information.
Preparation for Administration
Administer as an intravenous infusion only. Do not administer as an intravenous push or bolus. Do not mix PERJETA with other drugs.
