Study of Safety and Efficacy of an Oral Contraceptive

April 15, 2013 updated by: Warner Chilcott

An Open Label Study of the Contraceptive Efficacy of Norethindrone and Ethinyl Estradiol.

This is a non-comparative study. the primary objective of the study is to assess the efficacy of a low dose oral contraceptive in the prevention of pregnancy. The secondary objectives are to assess the incidence of intracyclic bleeding; and to assess the safety and tolerability of the product.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Healthy Women
  • Age 18-45
  • At risk for pregnancy
  • History of regular cycles

Exclusion Criteria:

  • Contraindications for use of hormonal contraception
  • Conditions which affect the absorption or metabolism of steroid hormones
  • BMI>35

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

How is the study designed?

Design Details

  • Primary Purpose: PREVENTION
  • Allocation: NON_RANDOMIZED
  • Interventional Model: SINGLE_GROUP
  • Masking: NONE

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Norethindrone/ethinyl estradiol
1 tablet per day
Drug: Norethindrone/ethinyl estradiol
1 tablet per day

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pearl Index, 18-35 Years, MITT Population
Time Frame: 13 cycles (28 days each), approximately 364 days
Pregnancy rate in women 18-35 years old, Pearl Index - number of pregnancies per 100 women-years of treatment
13 cycles (28 days each), approximately 364 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Mean Number of Days of Intracyclic Bleeding & Spotting, Cycles 2-13, MITT Population
Time Frame: 12 cycles (28 days each), approximately 336 days
12 cycles (28 days each), approximately 336 days
Mean Median Duration (Days) of Intracyclic Bleeding & Spotting, Cycles 2-13, MITT Population
Time Frame: 12 cycles (28 days each), approximately 336 days
Each IB episode has a unique duration, with 0, 1, 2, 3 or more episodes per cycle. To obtain "mean median duration" of episodes during a cycle, take the median duration of all episodes in each cycle. If there are no episodes in the cycle, then median duration is undefined/missing for that cycle. 1 episode - median duration = duration of that episode, 2 episodes - median duration = average of 2 durations, more than 2 episodes, calculated in usual way for median of an ordered set of numbers. Once median determined for each cycle/subject, the mean & SD of those quantities calculated.
12 cycles (28 days each), approximately 336 days

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2007

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
January 1, 2009

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
