Study Description

Brief Summary

A prospective, open-label, single arm, multicenter study to evaluate efficacy, safety and acceptability of pericoital oral contraception with levonorgestrel

Condition or Disease Intervention/Treatment Phase
Phase 3

Detailed Description

This is a prospective, open-label, single arm, multicenter study to evaluate efficacy, safety and acceptability of pericoital oral contraception with levonorgestrel (LNG). The objectives of the study as stated in the study protocol are as follows:

  • To evaluate the efficacy of the study regimen among women who have sex 1-4 days a month and who are relying on the study regimen as their primary method of contraception

  • To evaluate the safety of this regimen, with particular emphasis on its effects on vaginal bleeding patterns and anemia

  • To evaluate the acceptability of the regimen The study will enroll fertile women of reproductive age who have sex up to 6 days a month, are at low risk for sexually transmitted infections (STIs), have no contraindications to progestin-only oral contraceptives,have no serious contraindications to pregnancy, and are willing to use an investigational method of contraception as their only contraceptive method for 6.5 months (each tablet contains 0.75 mg LNG to be used after every sex act).

Outcome Measures

Primary Outcome Measures

  1. Efficacy: the Pearl Index (Number of Pregnancies Per 100 Woman-years) in the Primary Evaluable Population (18-35) [6.5 months]

    Participants were followed for 6.5 months.Pearl Index in the 18-35 year population was collected excluding months in which barrier methods, condoms, or emergency contraception were used unless the subject conceived

  2. Participant Report of Adverse Events. [6.5 months]

    Safety data includes data from each subject up to two weeks after her last use of the study tablets as well as all events deemed related to study product, regardless of date last tablet was taken

Secondary Outcome Measures

  1. Acceptability Based on Bleeding Patterns Reported [6.5 months]

    Number of participants who reported bleeding patterns were acceptable and would therefore use Levonorgestrel
