The Effect of Sulfasalazine on CRH Levels in Pregnant Women

United States50 participantsStarted 2023-03-01

Plain-language summary

The goal of this randomized clinical trial is to assess sulfasalazine as a potential treatment to prevent recurrent preterm birth. The main questions it aims to answer are: * Does sulfasalazine down regulate corticotropin releasing hormone (CRH) levels in pregnant persons with a prior history of preterm birth? * Does sulfasalazine reduce the incidence of recurrent preterm birth in pregnant persons given drug vs. controls? Consenting participants will be randomized to receive sulfasalazine or to a control group and will undergo serial blood draws to assess plasma CRH levels.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
