About this study
Official title: An Open-label Pharmacokinetic Drug Interaction Study of Folic Acid and 250 Mcg NGM/35 Mcg E E (ORTHO-CYCLEN) in Healthy Women.
The purpose of the study is to assess the effect of folic acid administration on the blood level and the breakdown products of oral contraceptive (OC) [250 mcg NGM/35 mcg EE] tablets.
Read the detailed description
This is an open-label, randomized (study drug assigned by chance), single-center, pharmacokinetic interaction study. Healthy adult women who met the prestudy eligibility criteria were randomized to 1 of 2 treatment groups. The randomization was balanced using permuted blocks. Healthy volunteers in Group 1 were to receive a single oral dose of 250 µg NGM/35 mcg EE (1 tablet) on Days 1 and 17, and 1 mg of folic acid on Days 4 through 18. Healthy volunteers in Group 2 were to receive a single, oral 1 mg dose of folic acid on Days 1 and 17, and 1 tablet on Days 2 through 17. Serial blood samples were to be collected from each healthy volunteer on Days 1 and 17 before dosing and at specified times for up to 72 hours after dosing for pharmacokinetic evaluation. Healthy volunteers were to be confined overnight at the study unit on Days -1 and 16 for an overnight fast of at least 8 hours before dosing on Days 1 and 17. Healthy volunteers were to remain confined at the study unit until the 24-hour blood samples were collected on Days 2 and 18. Safety was based on the incidence of adverse events, and on changes in clinical laboratory values, vital signs, electrocardiograms, and physical and gynecological examination findings. The Sponsor prematurely terminated this study on 14 February 2005 because of errors made at the study site in healthy volunteer randomization, the timing of blood draws, and handling of laboratory samples. As a result of these errors, the pharmacokinetic samples collected were not analyzed, and a new study was initiated (NRGMON-CON-1006). Due to the premature termination of the study, no healthy volunteer received more than 9 days of therapy. Most healthy volunteers completed the screening and premature termination procedures.
Oral contraceptives tablet (250 mcg NGM/35 mcg EE); Folic acid tablet (1 mg). Group 1: Single OC tablet on Days 1 and 17, 1 folic acid tablet on Days 4 to 18. Group 2: Single folic acid tablet on Days 1 and 17, 1 OC tablet on Days 2 to 17. The study drugs were to be taken with 240 mL (8 oz) of water at approximately 8:00 a.m. Healthy volunteers were required to fast for a minimum of 8 hours before dosing on Days 1 and 17.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evaluate the pharmacokinetic drug interaction between folic acid and OC (250 mcg NGM and 35 mcg EE) as measured by the pharmacokinetics of the active breakdown products of NGM, (norelgestromin [NGMN], and norgestrel [NG]) and EE.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2011.
