Update on TABLET (Thyroid AntiBodies and LEvoThyroxine) trial

The trial started recruitment in late 2011 and is due to end recruitment in December 2015 with follow up to end in October 2017. So far 688 patients have been recruited and over 15,000 have been screened for the thyroid antibody. The Trial is open nationally in 48 sites, nine of which have been opened recently. It is hoped that this final cohort of sites will boost recruitment figures so that the target of 900 is met.

If you would like to take part in the trial contact the TABLET team on 0121 4159111 or email tablet-trial@trials.bham.ac.uk

The TABLET trial is a randomised, double-blind, placebo-controlled trial which is looking at the role of thyroid antibodies in miscarriage. There is evidence that thyroid antibodies can influence important pregnancy outcomes such as increasing the risk of miscarriage and delivering a baby prematurely. The TABLET Trial is a national study in which all women trying for a pregnancy under the age of 41 are invited to have a blood test to see if they have thyroid antibodies.

We 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 lead researchers are keen to recruit as many women as possible so they can be sure that numbers are big enough to make the eventual results reliable. So if you might be interested in taking part, here’s what you need to know:

Who can take part?

The researchers are recruiting women who:

  • are aged 16 – 40
  • hope to conceive in the next year
  • Have had a previous miscarriage or due to have treatment for infertility
  • do not have known thyroid disease – and
  • are willing to be selected at random to have either the treatment or a placebo, without knowing which they are given.
