1015 Background: Gemcitabine (G), either as a single agent or in combination with taxanes, has demonstrated efficacy in MBC in phase II and III studies. We conducted a phase III study to compare time to progression (TTP) of G plus docetaxel (T) versus (vs.) T alone. The secondary endpoints included overall survival (OS), overall response rate (ORR), and toxicity. Methods: Females with HER-2-negative locally advanced or MBC and a WHO performance status ≤ 2 were randomized to GT (G 1,000mg/m2 day 1 + 8; T 75mg/m2 day 1) or T (100mg/m2 day 1) every 21 days. Pts were previously untreated, had prior anthracycline-based (neo)adjuvant chemotherapy or had received a single prior anthracycline-bsed chemotherapy regimen for MBC. Time-to-event endpoints were estimated using the Kaplan-Meier method, and the log-rank test was applied for comparisons between regimens. The planned sample size was 254 evaluable pts with α I and β of 0.05 and 0.90, respectively. Results: A total of 336 pts were randomized (170 GT; 166 T), data from one centre are yet missing and the present evaluation is based on data from 306 pts (155 GT; 151 T). The pts had a median age of 58 years in both regimens; range 36–73 years and 30–74 years, respectively. The median TTP was 7.5 months for the GT regimen vs. 6.5 months for the T regimen. The GT arm demonstrated an ORR of 44% vs. 38% in the T arm with 4 and 3 % complete responses, respectively. The OS was 13.4 vs. 13.2 months in the GT and T arm, respectively. Hematologic toxicity was common, especially grade 3–4 neutropenia (GT = 69%; T = 61%); infection was reported in 22 and 20% of the pts, respectively (none of the pts received G-CSF). The most commonly reported non-hematologic toxicities of grade 3–4 included mucositis (GT = 2%; T = 5%), diarrhea (GT = 4%; T = 7 %), fatigue (GT = 6%; T = 11%), oedema (GT = 10%; T = 3%), and peripheral neuropathy (GT = 9%; T = 28%). Conclusions: Preliminary data of GT as first- or second-line chemotherapy demonstrates a TTP advantage among HER-2-negative pts with advanced breast cancer. Updated results and proper statistical analyses will be presented. No significant financial relationships to disclose.
