Does Oral Desogestrel Prior to Insertion of the Etonogestrel Subdermal Implant Improve Continuation Rate at One Year?

Contraception Clinical Trial

Official title: Can a Three Months Treatment With Oral Desogestrel Prior to Insertion of the Etonogestrel Subdermal Implant Improve Continuation Rate at One Year?

Status Terminated

Clinical Trial Summary

Objective: The etonogestrel subdermal implant (ESI) is an effective and safe method of contraception. Although highly efficient, ESI produces often side effects that reduce its tolerance and acceptance. Daily oral desogestrel (DSG) prior to the insertion of ESI might help reduce its premature discontinuation. Our aim was to evaluate if this pre-treatment increases ESI's tolerance. Methods: Between 15.08.2016 and 30.09.2019, the investigators conducted a randomized prospective study of women aged 18 to 42 years who were interested to use Implanon and were willing to have 90 days of pre-treatment with DSG, in the family planning clinic of the Geneva University Hospitals and the Hospital of Basel. Women were randomized into either the study ESI only group or to the DSG + ESI group. In the DSG + ESI group, patients were given a 3 months' supply of 75µg of DSG before the insertion of the ESI. A 3 months visit was pre-programmed for all participants where the bleeding calendar and the questionnaires were collected. All patients were called over the phone after 12 months post ESI insertion in both groups.

Clinical Trial Description

Study and treatment periods 1 year of patient recruitment 15 months of follow up (90 days OD plus 1 year Implant or 1 year Implant) Measurements and Procedures: Assessment of premature ablation (PA) in months 3-12 (ESI only) or 3-15 (OD+ESI). This will require a contact with all patients at 12/15 months to verify if implant is still in place, and if it was removed, why (and possibly to also reassess symptoms). Women with known PA can be exempted from this follow-up. In case of PA, reasons will be explored and questioned. - Assessment of symptoms at 3 months only (bleeding calendar and satisfaction questionnaire, see below) - Assessment of willingness to receive implant at 3 months in OD+ESI group data collection is limited to these items, in order to limit burden on participants, and to focus resources on high quality of data (as opposed to quantity). ;
