The TABLET trial

The TABLET trial is an important research study which is looking at the role of thyroid antibodies in women with unexplained miscarriage.

The researchers are particularly interested in seeing whether a drug called Levothyroxine reduces the risk of miscarriage in women who have thyroid antibodies even though their thyroid hormones are in the normal range.

The trial is no longer recruiting.   A total of 952 women have been recruited to date and this is enough to show whether the treatment makes a difference or not.

The trial results are expected to be available in Spring 2018. This may seem like a very long time to be waiting for the trial results.  The reason for this time-frame is that the team needs to follow up all the women taking part throughout their treatment and pregnancies, once they conceive (and sadly, some won’t).   We will bring you the results as soon as they are available.

We’ve kept information about the trial below for those who would like to know about it.

TABLET is a randomised, double-blind, placebo-controlled trial:

Randomised The women who take part will be given either the treatment drug (Levothyroxine) or a placebo – a dummy drug that has no active ingredients. A computer makes the selection so it’s completely random.

Double-blind The women in the study won’t be told whether they are taking the active medicine or the placebo – and neither will their doctors. So both are blinded to this information.

Placebo-controlled Half the women in the study will have the active medicine and half (the controlswill have the placebo.  The medicine that they receive will look exactly the same to them and their doctors, but a completely separate group will keep a record of which women have Levothyroxine and which have the placebo.

Who can take part?
