The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Bayer
  Purpose
The purpose of the study is to investigate if the study drugs (tranexamic acid or mefenamic acid) can control irregular bleeding during the first 3 months of using Mirena. The study drugs tested are tested against placebo ("dummy medication not containing any active drug"). Treatment period is followed by a one-month period when study drugs are not taken but Mirena use is continued.

Condition Intervention Phase
Uterine Hemorrhage Drug: Tranexamic acid Drug: Mefenamic acid Drug: Placebo Drug: Mirena (Levonorgestrel IUS, BAY86-5028) Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: International, Prospective, Double-blind, 3-arm Comparative, Randomized, Placebo-controlled Phase IV Study on the Effect of Counseling and Either Tranexamic Acid or Mefenamic Acid or Placebo, on the Management of Bleeding/Spotting in Women Using the Levonorgestrel-releasing Intrauterine System (MIRENA) for Contraception.

Primary Outcome Measures:
  • The primary efficacy variable will be the cumulative number of bleeding / spotting days [ Time Frame: During 90 day double-blind treatment period ]

Secondary Outcome Measures:
  • To describe and compare the bleeding patterns observed in women during treatment period [ Time Frame: 90 day treatment period ]
  • To describe and compare the bleeding patterns observed in women during follow-up period [ Time Frame: During the 30 day follow-up period ]
  • Satisfaction with oral blinded study drug treatment for bleeding / spotting [ Time Frame: 90 day treatment period ]
  • Occurrence of dysmenorrhea [ Time Frame: During 120 day study period ]
  • Continuation rate with study drug [ Time Frame: During the 90 day treatment period ]
  • Continuation rate with Mirena [ Time Frame: During 120 day study period ]
  • Adverse Events Collection [ Time Frame: Until day 120 ]
  • Number of spotting-only days [ Time Frame: During the 90-day treatment period ]
  • Number of bleeding / spotting episodes [ Time Frame: During the 90-day treatment period ]
  • Length of bleeding / spotting episodes [ Time Frame: During the 90-day treatment period ]
  • Number of bleeding days with heavy intensity [ Time Frame: During the 90-day treatment period ]
  • Change in the number of B/S days between Day 60 and Day 90 of MIRENA use and the 30-day follow-up period [ Time Frame: Up to day 120 ]
  • Satisfaction with levonorgestrel-releasing intrauterine system [ Time Frame: Up to day 120 ]
  • Number of days of pain medication for dysmenorrhea during the 90 day treatment period [ Time Frame: During the 90-day treatment period ]
  • Number of bleeding-only days [ Time Frame: During the 90-day treatment period ]
