Recently, pertuzumab was approved with trastuzumab and docetaxel, based on outstanding survival data from the CLEOPATRA trial. Having used it a lot, Swain says, she recommends that the combination be used according to its indication. However, a study presented at the 2013 ASCO meeting showed a high response (about 50%) when paclitaxel was used instead of docetaxel, suggesting that either taxane could be acceptable for this patient population. Swain estimates that about 8,000 to 9,000 patients nationwide would be eligible for this treatment in the first-line setting.
Clinical Pearls
Beyond the first line, there are studies looking at trastuzumab and pertuzumab in heavily-pretreated patients. Studies are being done in this space, and while there is still not enough data, Swain says, she expects the combination to be effective.
