What is the Alife2 study?

Alife2 is a study investigating whether anti-coagulant (blood-thinning) treatment reduces the risk of miscarriage in women with two or more (unexplained) miscarriages and inherited thrombophilia- a blood-clotting problem.

If you might be interested in taking part in the Alife2 trial, here’s what you need to know:

Who can take part?

You may be able to take part in the trial if a blood test shows that you have inherited thrombophilia and:

  • You have had two or more miscarriages
  • You are aged between 18 and 42
  • You are trying for a baby, or plan to try, and are not yet pregnant and
  • You are willing to be ‘randomised’ – to be chosen at random – to either the trial treatment or standard care.

What would I need to do?

Participants randomised to trial treatment will be instructed in how to inject themselves once daily with a dose of anti-coagulant in either upper leg or abdomen. Treatment would start at or within 7 weeks of a confirmed pregnancy (based on first day of the last period) and continue until the start of labour or the end of the pregnancy.

Participants who are randomised to standard care won't need to inject themselves at all, but will be given the normal pregnancy care, although they will be followed up by the research team.
