randomized phase 2, dose-finding efficacy, safety study of anf-rho™ versus neulasta® in chemotherapy-induced neutropenia

Conditions: Chemotherapy-induced Neutropenia

Summary: randomized, open-label study to determine the dose, efficacy, safety and pharmacokinetic profile of anf-rho™ with once-per-cycle injection in comparison with neulasta in breast cancer patients at high risk of developing chemotherapy-induced neutropenia

forty eight (48) adult female, chemotherapy treatment-naïve, stage i to iii, breast cancer patients scheduled to receive fec100 (3 cycles)/docetaxel (3 cycles) myelosuppressive chemotherapy will be enrolled into the study after they meet all the inclusion/exclusion criteria. four (4) cohorts of 12 patients each will be studied; they will be randomized either in the anf-rho™ treatment arm at different doses (10 μg/kg, 20 μg/kg, or 30 μg/kg, for the cohorts 1-3, respectively) or neulasta® (6 mg / 0.6 ml sc injection, for cohort 4). for the cohorts 1-3, 12 patients from each of the respective anf-rho™ cohorts will be randomized with four patients from cohort 4 (neulasta®). patients in the anf-rho™ cohorts will receive study drug on day 1 of each chemotherapy cycle. patients in the neulasta® cohort will receive study drug on day 2 of each chemotherapy cycle. doses of anf-rho™/neulasta® will be provided for a total of 6 cycles (21 days each). the total duration of the study 129 ± 2 days (126 days of treatment period followed by end of study visit)
