e20593 Background: Pegfilgrastim (conjugate of filgrastim and 20 kDa polyethylene glycol (PEG) is approved for treatment of chemotherapy-associated neutropenia. BCD-017 (empegfilgrastim) is a covalent conjugate of filgrastim with 30 kDa PEG. Increased molecular weight of PEG molecule may provide additional benefits compared to pegfilgrastim. Methods: To compare efficacy and safety of filgrastim and BCD-017 at 3 mg and 6 mg doses an open-label, randomized, active-comparator, non-inferiority trial was conducted. 60 patients with histologically or cytologically confirmed breast cancer were randomly assigned to receive either subcutaneous (s.c.) injection of 3 mg BCD-017 (n=21), 6 mg BCD-017 (n = 20), or 5 mg/kg s.c. injections of filgrastim (n=19) administered daily until ANC ≥ 10x109 cells/L (maximum of 14 days) after chemotherapy (doxorubicin 60 mg/m2 and docetaxel 75 mg/m2) with stratification for weight and prior chemotherapy exposure. The primary efficacy endpoint was the incidence of severe neutropenia (ANC < 1.0x109 cells/L) during the first cycle of chemotherapy. Results: Incidence of severe neutropenia during the first chemotherapy cycle was 85,7%, 65,0% and 61,1% in BCD-017 3 mg, BCD-017 6 mg and filgrastim groups, respectively. Differences between BCD-017 groups and filgrastim group were not significant. Mean duration of grade 4 neutropenia in cycle 1 was 0,43, 0,40 and 0,33 days, accordingly (95% CI for difference between BCD-017 3 mg and filgrastim groups -0.22 to 0.41; 95% CI for difference between BCD-017 6 mg and filgrastim groups -0.25 to 0.38). Febrile neutropenia was observed only in BCD-017 3 mg and BCD-017 6 mg groups (one case in each group). A single administration of BCD-017 at the doses of 3 mg and 6 mg was as safe and well tolerated as standard daily filgrastim administration. There were no unexpected adverse events in all groups. Conclusions: The results of this study support comparable efficacy of single s.c. injection of 6 mg BCD-017 versus daily 5 mg/kg s.c. injections of filgrastim. Further phase III study of BCD-017 for treatment and prophylaxis of neutropenia in patients receiving chemotherapy is necessary. Clinical trial information: NCT01569087.

10526 Background: Due to high activity of taxanes (T) and anthracyclines (A) in advanced breast cancer (BC) and to the lack of cross-resistance between them, several adjuvant (adj) trials have been performed to test the efficacy of combination or sequential schedules of T and A adjuvant. In most of the sequential trials A followed T. The sequence T->A was proven active in metastatic BC, but no data are available in the adj setting. This multicenter randomized phase III study was designed to evaluate the efficacy of the sequence T->A vs an A containing regimen Methods: Pts with pT1–3 pN1 M0 (UICC1997) BC, age 18–70, PS(ECOG) 0–1, normal cardiac function, adequate bone marrow, hepatic and renal function were eligible for the study. Pts were stratified according to institution, age (≤ 50 vs > 50), hormonal receptor status and number of involved nodes (≤ 3, 4–9, ≥ 10) and were randomized to receive either 4 cycles of EC (Epirubicin 120 mg/m2 + Cyclophosphamide 600 mg/m2 on day 1 q21) in arm A or 4 cycles of D (100 mg/m2 on day 1 q21) followed by 4 cycles of EC in arm B. Primary endpoint was DFS. Secondary endpoints OS and toxicity. Results: Between april 1999 and october 2005, 750 pts were enrolled (374 in arm A and 376 in arm B) in 25 Italian institutions. Pts characteristics are as follows: Arm A: age ≤ 50 yrs 185/374; ≤ 3 nodes 182/374, 4–9 nodes 129/374, ≥ 10 nodes 63/374; positive HR 287/374 Arm B: age ≤ 50 yrs 197/376; ≤ 3 nodes 184/376, 4–9 nodes 131/376, ≥ 10 nodes 61/376; positive HR 289/376 Toxicity data (Arm A vs Arm B) of the first 495(241/254) pts are the following: Neutropenia G3 (29% vs 21.3%), neutropenia G4 (32.7% vs 48.8%), febrile neutropenia G3–4 (3.7% vs 9.5%), thrombocytopenia G3–4 (3.3% vs 1.6%), anemia G3 (0% vs 2.4%), N/V G3–4 (6.2% vs 3.1%), mucositis G3–4 (3.7% vs 3.9%), diarrhea G3–4 (0.4% vs 2.8%), peripheral neuropathy G1–3 (0% vs 9.9%), hypersensitivity reactions G3–4 (0% vs 4.3%), cardiac toxicity G3 (0.4% vs 0%) Conclusions: Treatment was generally well tollerated in both arms with a higher incidence of neutropenia, usually short lasting, in arm B. The use of prophylactic G-CSF in those patients experiencing neutropenia G3–4 may be advisable. There were no significant differences in cardiac toxicity. No significant financial relationships to disclose.
