RYZNEUTA

The pharmacokinetics of efbemalenograstim alfa-vuxw was studied in female patients with breast cancer and healthy male subjects. Efbemalenograstim alfa-vuxw exhibited nonlinear and time-dependent pharmacokinetics over the dose range of 30 to 360 μg/kg. At the approved recommended dose in healthy subjects, the mean (%CV) C max was 1202 ng/mL (56%), and the AUC 0-inf was 76357 h*ng/mL (65%). At the approved recommended dose in patients with breast cancer, the geometric mean (CV%) Cmax was 1085 ng/...

The efficacy of RYZNEUTA to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with nonmyeloid malignancies receiving myelosuppressive anti-cancer drugs was evaluated in two randomized, controlled studies. Study GC-627-04 [NCT02872103] was a randomized, double-blind, placebo-controlled study that employed doxorubicin 60 mg/m 2 and docetaxel 75 mg/m 2 administered every 21 days for up to 4 cycles for the treatment of metastatic or non-metastatic breast cancer. In this study, 122 patients were randomized to receive a single subcutaneous injection of RYZNEUTA (...
