Safety and Tolerability
GEMZAR for the first-line treatment of metastatic breast cancer.

Abbreviated Adverse Events (% Incidence)
The most severe adverse events (grades 3/4) with GEMZAR plus paclitaxel versus paclitaxel, respectively, for the treatment of patients with MBC were neutropenia (48 vs 11); alopecia (18 vs 22); leukopenia (11 vs 2); anemia (7 vs 4); fatigue (7 vs 2); thrombocytopenia (6 vs 2); ALT elevation (6 vs 1); and neuropathy-sensory (6 vs 3). The most common adverse events (all grades) were alopecia (90 vs 92); anemia (69 vs 51); neutropenia (69 vs 31); neuropathy-sensory (64 vs 58); nausea (50 vs 31); fatigue (40 vs 28); myalgia (33 vs 33); vomiting (29 vs 15); and thrombocytopenia (26 vs 7).
G-CSF was not used prophylactically in this trial. Actual use: 7.6% (gemcitabine/paclitaxel) and 1.2% (paclitaxel) respectively.
† Refer to NCI CTC, Version 2.0.
‡ Regardless of causality.
§ Nonlaboratory events were graded only if assessed to be possibly drug-related.

*Adverse events >1% and <10% (all grades).
Note: 7% of patients on the GEMZAR/paclitaxel arm and 5% of patients on the paclitaxel arm discontinued the study due to adverse events.

Overall, >90% of the GEMZAR dose was delivered in the combination arm, while 100% of the paclitaxel dose was delivered for both arms.
Note: There was a strong trend toward improved survival for the group given GEMZAR based on an interim survival analysis.
GEMZAR in combination with paclitaxel is indicated for the first-line treatment of patients with metastatic breast cancer after failure of prior anthracycline-containing adjuvant chemotherapy, unless anthracyclines were clinically contraindicated.
Myelosuppression is usually the dose-limiting toxicity with GEMZAR therapy.
