Read the detailed description

This is a randomized double blind placebo controlled trial comparing Nifedipine 30mg XL to placebo in 110 patients after decision has been made to proceed with induction of labor for the diagnosis of preeclampsia with severe features.

After diagnosis of preeclampsia with severe features and decision made to proceed with induction of labor. Patients were approached about study and if consented then were then randomized to placebo or nifedipine 30XL daily until delivery occurred.

Being tested
Nifedipine 30 MG, Placebos

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Nifedipine 30 MGDrug

    Nifedipine XL is a long-acting medication used to lower blood pressure. The investigators want to learn whether women who receive the study drug will experience fewer severe-range blood pressure readings, and therefore need fewer intravenous (IV) medications to safely lower blood pressure.

  • PlacebosDrug

    At the time of enrollment, patients will be randomized to either the study drug (oral Nifedipine XL 30mg) or identical placebo.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With the Change in Blood Pressure (Both Systolic and Diastolic) Under the Treatment of NIfedipine 30mg XL Versus Placebo

    Measured acute antihypertension therapy between enrollment and delivery

    Measured: Between enrollment and delivery, assessed up to 18 weeks

Secondary outcomes (4)
  1. Number of Participants Stratified by Route of Delivery

    Measured: At delivery

  2. Number of Participants With Various Indications for Cesarean Delivery

    Some participants could have more than one indication for Cesarean Delivery.

    Measured: Between enrollment and delivery, assessed up to 18 weeks

  3. Number of Participants With Hypotension of ≥30% Decrease in Blood Pressure From Baseline Following Acute Antihypertensive Therapy

    Measured: Between enrollment and delivery, assessed up to 18 weeks

  4. Number of Participants Who Required Acute Antihypertension Treatments Postpartum

    Measured: At delivery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Nifedipine 30 MG in people with Preeclampsia Severe, run by Ohio State University at 1 site in United States.

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 2 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 24 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Jul 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With the Change in Blood Pressure (Both Systolic and Diastolic) Under the Treatment of NIfedipine 30mg XL Versus Placebo (time frame: Between enrollment and delivery, assessed up to 18 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04392375, which also lists 1 linked publication.

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 24 Jul 2023.
