Официальное название
A Prospective, Controlled Study to Assess the Preliminary Efficacy and Safety of Topefilgrastim Injection in High-Risk Pregnant Patients With Preeclampsia.
Обзор
This study is an open-label, prospective investigation designed to enroll 100 high-risk pregnant subjects with preeclampsia (PE). Participants will be allocated in a 2:2:1 ratio to one of three groups: the Topefilgrastim 0.5mg/biweekly group, the Topefilgrastim 1mg/biweekly group, or the control group, based on investigator judgment and patient preference. The overall study consists of three parts: a screening period, a treatment period, and a follow-up period.
