Therapeutic Equivalence Trial of Two Hormonal-IUDs in Patients With Heavy Menstrual Bleeding
- Registration Number
- NCT01695902
- Lead Sponsor
- Uteron Pharma S.A.
- Brief Summary
The primary objective of this study was to compare the efficacy of Test Product (Levosert) vs. Reference Product (Mirena® Bayer-Schering) based on the mean variation of menstrual blood loss volume in women with menorrhagia.
The secondary objectives includes physical and gynaecological examinations, vital signs, clinical laboratory tests including hemoglobin and ferritin measurements, body weight and spontaneously reported adverse events were analysed and compared between Levosert and Mirena® treatment arms. Plasma levels of levonorgestrel (LNG) were also evaluated after various periods of time. The residual amounts of LNG in the devices were finally measured after withdrawal at completion of the study. Plasma levels of LNG and residual amounts of LNG were compared between the two treatment groups. Contraceptive effect of Levosert was estimated by Pearl Index.

- Primary Outcome Measures
Name Time Method Mean change from baseline to Year 1 in the mean menstrual blood loss volume measured using the modified Wyatt pictogram in the two treatment groups 1 year
- Secondary Outcome Measures
Name Time Method Comparison of the plasma levels of LNG (Levonorgestrel) in the 2 treatment groups up to three years Comparison of the residual LNG level in the IUS in the 2 treatment groups up to three years Mean reduction in menstrual blood loss volume from baseline to intermediate cycles (equivalent to 28-days period) 1 year
