ClinConnect Summary
This clinical trial is studying a medication called telpegfilgrastim to see if it is safe and well-tolerated in healthy women who are not pregnant and are between the ages of 18 and 45. The trial aims to understand how the drug works in the body after a single dose. Researchers will enroll 18 women, who will receive different doses of the medication and will be monitored closely for any side effects and changes in their health for up to 21 days after taking the drug.
To participate, women need to meet certain criteria, such as being healthy, having a body mass index within a specific range, and agreeing to use reliable contraception during the study. Participants will go through a series of health checks before starting the trial, and they must be comfortable with providing blood samples. It’s important to note that women with certain medical conditions, recent infections, or those taking specific medications may not be eligible. Overall, this study is crucial for understanding the potential of telpegfilgrastim in addressing conditions like preeclampsia, which affects pregnant women.
