About this study

Official title: Effect of Levothyroxine Treatment on Pregnancy Outcome in RPL Women With Subclinical Hypothyroidism

The present study is divided into two groups ,one is the patients with subclinical hypothyroidism who has TPO antibody positive women with TSH concentrations > 2.5 mU/L and below the upper limit of the pregnancy specific reference range ,another is TPO antibody negative with TSH concentrations greater than the pregnancy specific reference range and below 10.0 mU/L.The two groups are randomized into either the LT4 treatment group or control group by the use of a computer-generated list.

The aim of our study is to determine whether the use of levothyroxine is beneficial in patients with subclinical hypothyroidism in two groups。

Read the detailed description

Many studies have stratified the risk imparted by hypothyroidism according to TPOAb status, and consistently show that this risk is higher in TPOAb positive women. Some data also suggest that the adverse impact associated with maternal TSH levels is apparent at lower TSH elevations in women known to be TPOAb positive compared to women who are TPOAb negative. Furthermore, studies suggest a reduction in pregnancy loss when TPOAb positive women are treated with levothyroxine, even when biochemically euthyroid. Intervention trials have not been performed in TPOAb negative women. A etiology analysis process,from June 2010 to June 2015 in The Second Affiliated Hospital of Soochow University, were showed that 22.2% of total 917 cases who had RPL history present as abnormal serum TSH level or positive TPOAb, while 36.6% of 523 cases who repregnancy present as abnormal.This present study is divided into two groups ,one is the patients with subclinical hypothyroidism who hasTPO antibody positive women with TSH concentrations > 2.5 mU/L and below the upper limit of the pregnancy specific reference range ,another is TPO antibody negative with TSH concentrations greater than the pregnancy specific reference range and below 10.0 mU/L.The two groups are randomized into either the LT4 treatment group or control group by the use of a computer-generated list.For the LT4 treatment group, 50μg LT4 (Merck Serono, Geneva,Switzerland) was administered every morning from the first day of diagnosed as subclinical hypothyroidism and continued up to the day of serum β-HCG measurement.If pregnancy was confirmed, levothyroxine dose need to increase 25-30% and be adjusted according to the pregnancy specific reference range ( T1 0.1-2.5mIU/L,T2 0.2-3.0mIU/L, T3 0.3-3.0mIU/L).For the control group ,women with subclinical hypothyroidism are not given any drugs . The aim of our study is to determine whether the use of levothyroxine is beneficial in patients with subclinical hypothyroidism who has TPO antibody positive women with TSH concentrations > 2.5 mU/L and below the upper limit of the pregnancy specific reference range or TPO antibody negative with TSH concentrations greater than the pregnancy specific reference range and below 10.0 mU/L.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LevothyroxineDrug

    Also called LT4

    Levothyroxine is an orodispersible tablet.For the LT4 treatment group, 50μg LT4 (Merck Serono, Geneva,Switzerland) was administered every morning from the first day of diagnosed as subclinical hypothyroidism and continued up to the day of serum β-HCG measurement.If pregnancy was confirmed, levothyroxine dose need to increase 25-30% and adjusted according to the pregnancy specific reference range ( T1 0.1-2.5mIU/L,T2 0.2-3.0mIU/L, T3 0.3-3.0mIU/L) .

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Gestational week at delivery

    The research doctor site telephoned every participant 2 weeks after the expected date of delivery to obtain pregnancy outcome data.

    Measured: 28 weeks

  2. Newborn birth weight

    The research doctor site telephoned every participant 2 weeks after the expected date of delivery to obtain newborn birth weight.

    Measured: at birth

  3. APGAR Score at birth

    The APGAR (Appearance, Pulse, Grimace, Activity, Respiration) scale is determined by evaluating the newborn baby on five simple criteria on a scale from zero to two, then summing up the five values thus obtained. The resulting APGAR score ranges from zero to 10.

    Measured: at birth

Secondary outcomes (3)
  1. Number of clinical pregnancy at 6-8 weeks (defined as the presence of a gestational sac, with or without a yolk sac or fetal pole)

    The research doctor site telephoned every participant at between 6 and 7 weeks of gestation, to ensure there were arrangements for an ultrasound appointment with her usual carers, before 8 weeks of gestation. If an appointment had not been booked, the research doctor assisted with booking. The research doctor telephoned each participant again between 3 and 5 days after the scheduled date of the ultrasound appointment, to obtain details of the observations of a gestational sac.

    Measured: 8 weeks

  2. Number of ongoing pregnancy at 12 weeks (defined as the presence of a fetal heartbeat)

    The research doctor site telephoned each participant between 10 and 12 weeks of gestation, to ensure there were arrangements for an ultrasound appointment with her usual carers, at between 12 and 14 weeks of gestation. As previously, the research doctor assisted with booking an appointment if necessary, and telephoned the participant afterwards to obtain details of variables such as fetal heartbeat. The research doctor also recorded the expected date of delivery at this stage.

    Measured: 12weeks

  3. Number of miscarriage (defined as loss of pregnancy before 28 weeks of gestation).

    The research doctor site telephoned each participant before28 weeks of gestation, to obtain their pregnancy outcomes such as miscarriage.

    Measured: 28 weeks

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Levothyroxine in people with Recurrent Pregnancy Loss, run by Second Affiliated Hospital of Soochow University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 12 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Gestational week at delivery (time frame: 28 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03106935, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Apr 2017.
