General information about the trial
|
|||
Main objective of the trial |
Feasibility study: This study is testing whether women between 28+0 and 35+6 weeks pregnant who come to hospital with signs and/or symptoms of preterm labour would be willing to take a medication (pravastatin) or placebo in a blinded fashion for 7 days.
|
||
Protection of trial subjects |
Participants were offered a information by a member of their clinical care team at the time of presentation. Women presenting with sign of preterm labour are often anxious and consideration was provided to ensure that they had time to consider participation. Whilst the nature of the intervention is time-critical, they will of course be offered as long as required to consider participation.
