CLINICAL TRIALS PROFILE FOR MIRENA

All Clinical Trials for mirena

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00185380 ↗	Dose-finding Study for the Ultralow-dose Levonorgestrel Intrauterine Contraceptive System (LCS)	Completed	Bayer	Phase 2	2005-04-01	The purpose of this study is to investigate if drug doses lower than the one released from Mirena® would be as effective for contraception as Mirena®. Subjects participating in the study will be randomly assigned to be inserted with any of the three different intrauterine systems (IUSs). The IUSs are nearly alike except that the amount of hormone released from them is different.
NCT00360490 ↗	Study in Women With Idiopathic Menorrhagia to Determine the Reduction in Menstrual Blood Loss (MBL) After Treatment With the Levonorgestrel-releasing Intrauterine System (IUS)	Completed	Bayer	Phase 3	2006-07-01	The purpose of this study is to determine whether the levonorgestrel-releasing intrauterine system is effective in decreasing menstrual blood loss.
NCT00393198 ↗	Bleeding Pattern and User Satisfaction During Second Consecutive MIRENA® in Contraception and Treatment of Menorrhagia	Completed	Bayer	Phase 4	2006-10-01	The purpose of this study is to assess the bleeding pattern during the last 3 months of the first MIRENA® and the first year of the second MIRENA® use.
NCT00445887 ↗	Levonorgestrel in Preventing Ovarian Cancer in Patients at High Risk for Ovarian Cancer	Completed	National Cancer Institute (NCI)	Phase 2	2008-03-10	This randomized phase II trial is studying how well levonorgestrel works in preventing ovarian cancer in patients at high risk for ovarian cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of levonorgestrel may prevent ovarian cancer.
NCT00445887 ↗	Levonorgestrel in Preventing Ovarian Cancer in Patients at High Risk for Ovarian Cancer	Completed	Gynecologic Oncology Group	Phase 2	2008-03-10	This randomized phase II trial is studying how well levonorgestrel works in preventing ovarian cancer in patients at high risk for ovarian cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of levonorgestrel may prevent ovarian cancer.
NCT00475228 ↗	'Levonorgestrel IUD Insertion After D&E Procedure	Completed	University of Pittsburgh	Phase 4	2007-03-01	This study is a randomized controlled trial of insertion of the levonorgestrel-releasing intrauterine device (LNG-IUD) immediately following dilation & evacuation (D&E) compared to delayed insertion 3-6 weeks post-D&E. Eighty-eight women undergoing D&E between 15 0/7 and 23 6/7 weeks gestation will be enrolled at Magee-Womens Hospital, Pittsburgh, PA. The primary outcome is LNG-IUD usage six months following enrollment. We hypothesize that more women receiving immediate insertion will be using the LNG-IUD 6 months after the D&E procedure than women receiving delayed insertion. Secondary outcomes include the proportion receiving an IUD, continuation rate, complication rates, subject satisfaction, and quality of life. The utility of ultrasonography in predicting expulsion will also be examined. Anticipated problems include poor subject follow-up and coordinating the intra-operative study procedures.
NCT00498784 ↗	HR-QoL and Sexuality in Mirena Inserted Contraception Users	Completed	Bayer	Phase 4	2005-11-01	The purpose of this study is to evaluate the changes in the quality of life, as well as in the sexual activity, in women inserted with MIRENA, a hormonal contraceptive intra-uterine system, over the first 12 months of use. Patients switching from oral contraception to an intrauterine contraceptive device (here: MIRENA) will be observed in the first year post MIRENA insertion.
