Figure 1: Kaplan–Meier Curve of Progression Free Survival in Gemzar Plus Carboplatin Versus Carboplatin in Ovarian Cancer (N=356)
Breast Cancer
Data from a multi–national, randomized Phase 3 study (529 patients) support the use of Gemzar in combination with paclitaxel for treatment of breast cancer patients who have received prior adjuvant/neoadjuvant anthracycline chemotherapy unless clinically contraindicated. Gemzar 1250 mg/m2 was administered on Days 1 and 8 of a 21–day cycle with paclitaxel 175 mg/m2 administered prior to Gemzar on Day 1 of each cycle. Single–agent paclitaxel 175 mg/m2 was administered on Day 1 of each 21–day cycle as the control arm.
The addition of Gemzar to paclitaxel resulted in statistically significant improvement in time to documented disease progression and overall response rate compared to monotherapy with paclitaxel as shown in Table 4 and Figure 2. Further, there was a strong trend toward improved survival for the group given Gemzar based on an interim survival analysis.
