Study summary

The purpose of this study is to determine that once-a-month injectable contraceptive( Cyclofem® ) has the effect on treatment of irregular uterine bleeding in implant contraceptive users or not.

Read the detailed description

Stratified randomization Implanon and Jadelle group were done using block randomization. The participants and investigators were blinded to treatment allocation, using drug coding that not revealed until the end of study. Research assistants and nurse who did not have involve in analyses data would follow the recruitment criteria and drug injection follow the code of drug.

All participants were collected demographic data, medical history, obstetrical and gynecological history, bleeding pattern before enrollment. Then physical exam and pelvic examination were performed for all participants. Participants received single dose intramuscular injection of Cyclofem® 0.5 ml or normal saline 0.5 ml as placebo on that day of recruitment to the study. Daily record of bleeding, spotting and side effect was done on record form.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 30, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
