Study summary

The purpose of this study is to demonstrate that a new device inserter leads to successful and safe insertion of Paragard® IUS, comparable to the currently approved IUS inserter, in females of reproductive potential.

Read the detailed description

This is a post-market prospective clinical study to be conducted at multiple centers in a single arm and open-label design to evaluate the safety of a new inserter design for Paragard® (intrauterine copper contraceptive). The study will be conducted in female subjects of child bearing potential.

    Paragard® T380A Intrauterine Copper Contraceptive with new inserter Non parous and parous female subjects of child bearing potential

    Combination Product: Paragard® T380A Intrauterine Copper Contraceptive with New Inserter

Interventions

  • Combination productParagard® T380A Intrauterine Copper Contraceptive with New Inserter

    Paragard® IUS with Investigational Inserter combines the current insertion tube and white rod to form a new pre-assembled inserter device that supports a single hand operation. The device is used to pass the IUS through the cervical canal and into the uterine cavity and facilitates insertion of the T shaped Paragard® IUS implant into the uterus.

What researchers measure

Primary outcomes

  1. Overall Successful Insertions

    The percentage of successful insertions will be calculated by number of subjects with successful insertions relative to the total number of subjects with at least one successful or unsuccessful insertion attempt. A successful insertion includes participants with at least one successful insertion attempt with a maximum of two attempts.

    Time frame: From enrollment to end of treatment at 3 months

Secondary outcomes

  1. Number of Participants With Uterine Perforation and IUD Embedment

    Frequency of uterine perforation and IUD embedment

    Time frame: From enrollment to end of treatment at 3 months

  2. Number of Participants With IUS Expulsions and Dislocations

    Frequency of IUS expulsions (partial or total) and dislocations

    Time frame: From enrollment to end of treatment at 3 months

  3. Number of Participants With Adverse Events

    Frequency of Serious Adverse Events (SAE) and Adverse Events (AE)

    Time frame: From enrollment to end of treatment at 3 months

  4. Number of Participants With Adverse Events Related to Procedure

    Frequency of AEs related to procedure

    Time frame: From enrollment to end of treatment at 3 months

  5. Number of Participants With Vasovagal Events

    Frequency of vasovagal events at the time of insertion

    Time frame: From enrollment to end of treatment at 3 months

  6. Number of Participants With Pelvic Infections

    Frequency of pelvic infections related to IUS insertion and use

    Time frame: From enrollment to end of treatment at 3 months
