About this study
The Achieve Trial is a randomized clinical trial to test whether lowering blood pressure to less than 140/90 mmHg in women with hypertensive disorders of pregnancy will prolong pregnancy.
Read the detailed description
Hypertensive disorders of pregnancy, including gestational hypertension and preeclampsia, are characterized by new onset high blood pressure in pregnancy and constitute a major cause of maternal and perinatal morbidity and mortality; severe hypertension (blood pressure ≥160/110 mmHg) is a common trigger for antihypertensive treatment and preterm delivery. We propose a clinical trial that will test whether lowering the blood pressure in women with hypertensive disorders of pregnancy at <36 weeks' gestation to <140/90 mmHg will prolong pregnancy and, therefore, improve maternal and fetal/neonatal outcomes. Data generated in this study, along with knowledge and skills acquired by the candidate in the complementary career development plan, will facilitate an independent research career focused on hypertension and cardiovascular disease in pregnancy.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The Achieve Trial is a randomized clinical trial to test whether lowering blood pressure to less than 140/90 mmHg in women with hypertensive disorders of pregnancy will prolong pregnancy.
Detailed description
Hypertensive disorders of pregnancy, including gestational hypertension and preeclampsia, are characterized by new onset high blood pressure in pregnancy and constitute a major cause of maternal and perinatal morbidity and mortality; severe hypertension (blood pressure ≥160/110 mmHg) is a common trigger for antihypertensive treatment and preterm delivery. We propose a clinical trial that will test whether lowering the blood pressure in women with hypertensive disorders of pregnancy at <36 weeks' gestation to <140/90 mmHg will prolong pregnancy and, therefore, improve maternal and fetal/neonatal outcomes. Data generated in this study, along with knowledge and skills acquired by the candidate in the complementary career development plan, will facilitate an independent research career focused on hypertension and cardiovascular disease in pregnancy.

Questions about this trial
What is this clinical trial studying?
A study testing Antihypertensive treatment in people with Preeclampsia and Gestational Hypertension, run by University of Alabama at Birmingham at 2 sites 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 8 inclusion and 16 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: looking for participants now, as of the sponsor's last update on 12 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Rachel Sinkey, MD (205-934-5611, rsinkey@uabmc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean number of days from randomization to delivery (time frame: From randomization to delivery, up to 14 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 NCT05676476, which also lists 12 linked publications.
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 12 Dec 2025.
