Chemotherapy-induced Thrombocytopenia
Conditions
Brief summary
To evaluate the efficacy and safety of QL0911 to prevention chemotherapy-induced thrombocytopenia. Thrombocytopenia is a low number of platelets in the blood. Sometimes, thrombocytopenia occurs as a side effect of chemotherapy treatments.
Detailed description
For the phase III study, a double-blind randomized, placebo controlled, parallel-group design will be conducted to evaluate the efficacy and safety of QL0911 . Each subject will be randomly assigned to either Arm A (QL0911) or Arm B (placebo) in 2:1 ratio.The primary objective is to compare the effective rates of the two treatment arms. The study will consist of a screening period of up to 4 weeks, a treatment period of 2 planned cycles of chemotherapy, a follow-up visit of 2 weeks.
