E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate if tranexamic acid and/or mefenamic acid are superior
to placebo in the management of bleeding/spotting during the first
90 days of levonorgestrel-releasing intrauterine system use. |
|
E.2.2 | Secondary objectives of the trial |
-To compare the number of bleeding/spotting (B/S) days during the 30-day follow-up period in the 3 treatment groups, and the change in the number of B/S days between Day 60 and Day 90 of levonorgestrel-releasing intrauterine system use and the 30-day follow-up period in the 3 treatment groups.
-To investigate subject satisfaction and continuation rate with tranexamic acid, mefenamic acid, or placebo treatment for B/S.
-To investigate subject satisfaction and continuation rate with the
levonorgestrel-releasing intrauterine system in women treated with tranexamic acid, mefenamic acid, or placebo.
-To investigate the safety of tranexamic acid and mefenamic acid in the management of B/s during the first 90 days of levonorgestrel-releasing intrauterine system use.
-To investigate the occurrence of dysmenorrhea before and after
levonorgestrel-releasing intrauterine system insertion and the effect blinded study drug treatment for B/S on the need of pain medication for
dysmenorrhea. |

-Active or history of peptic ulcer/hemorrhage
-Any diseases or conditions that can compromise the function of the body systems and could result in altered absorption, excessive accumulation, impaired metabolism, or altered excretion of the investigational medicinal products (e.g. severe renal, liver or heart failure)
-Hypersensitivity to any ingredient of the investigational medicinal products (TXA,
MFA, and placebo) or the non-investigational medicinal product (MIRENA)

-Not willing to use non-NSAID medication as pain medication during the double-blind
treatment period
-Other medication known to affect vaginal bleeding pattern (including, but not limited
to, TXA, daily use of NSAIDs, gonadotropin-releasing hormone (GnRH) analogues,
danazol, progestins, estrogens, anticoagulants) is prohibited during the whole study
-Long-acting preparations (e.g. DMPA, monthly contraceptive injection, contraceptive
implant) within 3 months before start of treatment

IUDs, and implants is prohibited during the whole study
-Abuse of alcohol, drugs, or medicine (e.g. laxatives)

study prior to study entry that might have an impact on the study objectives, at the
discretion of the investigator.
-Major surgery scheduled for the study period

interpretation of the results
-Close affiliation with the investigational site; e.g. a close relative of the investigator,
dependent person.
-Inability to cooperate with the study procedures for any reason, including the following examples: language comprehension, psychiatric illness, inability to get to the study site
-Previous assignment to treatment (e.g. randomization) during this study (allowing
previously randomized subjects to be re-included into the study may lead to bias) |
