April 7, 2015 updated by: Mahidol University

A Comparison of Body Weight Changing and Side Effects Between Treatment With 30 mcg Ethinylestradiol/2 mg Chlormadinone Acetate (Belara®) and 30 mcg Ethinylestradiol/3 mg Drospirenone (Yasmin®): A Randomized Control Trial

The purpose of this study is to evaluate different side effect in contraceptive use of two oral combined contraceptive pills (OCP)in combination of 30 mcg ethinylestradiol/2 mg chlormadinone acetate (Belara®) and 30 mcg ethinylestradiol/3 mg drospirenone (Yasmin®), especially body weight change.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

Oral combined contraceptive pills (OCP) is the most contraceptive use in reproductive women. The various type of progestins in OCP give various effects either benefit (non-contraceptive benefit) and side effect. These effects depend on pharmacological activity of each progestin. Many studies showed causes of discontinuation use of OCP, such as increase body weight,androgenic effect and vaginal spotting. OCP in combination of 30 mcg ethinylestradiol/2 mg chlormadinone acetate (Belara®) and 30 mcg ethinylestradiol/3 mg drospirenone (Yasmin®)are the common used in practice. The each type of progestin (chlormadinone and drospirenone) might effect different outcomes in women especially in body weight change during use. Chlormadinone is a C-21 progestin which has glucocorticoid and antiandrogenic effect. Drospirenone is a progestin in spironolactone derivative which has antimineralocorticoid and antiandrogenic effect. Both progestins might has less effect in body weight change and provide other non-contraceptive benefits. So investigator want to study the different effects from these progestin in two type of OCP. The result from this study could give information to choose the proper OCP for each reproductive woman.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
body weight change
Time Frame: 6 month
Compare the body weight change during use of two OCP (30 mcg ethinylestradiol/2 mg chlormadinone acetate (Belara®) and 30 mcg ethinylestradiol/3 mg drospirenone (Yasmin®)). By follow up at 3rd and final at 6th month of use.
6 month

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
efficacy in contraception (pregnancy rate)
Time Frame: 6 month
To evaluate contraceptive efficacy of two OCP. Urine pregnancy test was used to evaluate pregnancy, the participant was tested in every visit of the study.
6 month
Other side effects
Time Frame: 6 month
To evaluate other side effects during using both OCP,such as vaginal spotting, androgenic effect, blood pressure, headache and GI effect. Vaginal spotting was classified by number of pad (WHO definition) which the participant used in each cycle and record in menstrual card. Androgenic effect was classified by Modified Ferriman - Gallway Score for hirsutism (score > 7), American Academy of Dermatology Consensus 2009 on acne classification (mild, moderate, severe)for acne, systolic/diastolic blood pressure and the presence or no presence of headache and GI discomfort.
6 month
satisfaction
Time Frame: 6 month
To compare satisfaction in study process. In each visit (first, 3rd month and 6th month of study period). The participant was evaluated satisfaction in topics of diagnosis, timing of study process, information from the staff about the study process and the way to use oral pills, quality of the oral pills and conclusive satisfaction. The rating of satisfaction was categorised in five levels as five scoring numbers by using questionnaire; 5=extreme satisfaction, 4=very satisfaction, 3=moderate satisfaction, 2= little satisfaction, 1=no satisfaction.
