Analysis of reasons for failure in screening healthy menopausal female subjects in a bioequivalence trial
Objective To clarify and analyze the reasons for failure in screening healthy menopausal female in a bioequivalence trial.Methods To summarize and clarify the data of 185 healthy menopausal female subjects participating in a bioequivalence trial of estradiol valerate conducted,and summarize the reasons for screening failure.Results The main reasons for screening failure include laboratory tests(32.04%),gynecological transvaginal color Doppler ultrasound(16.57%),vital signs(14.36%),chest computed tomography(CT,11.60%),and medical history/medication history(7.73%).Conclusion Screening failures in healthy menopausal female subjects were characterized mainly by abnormal gynecological transvaginal color Doppler ultrasound and non-compliance with basal hormone levels compared to generally healthy subjects.
