Brief Summary

Recurrent miscarriage (RM) defined by \>=3 consecutive losses affects 1% of fertile couples. Most women have recurrent early loss with a failure of development before 10 weeks' gestation. Standard investigations fail to reveal any apparent cause in \>50% of couples. No study has demonstrated any benefit of any medication in women with Unexplained RM, in the presence or absence of an inherited thrombophilia. Moreover, the benefit of aspirin and/or heparin has not been proved in women with Antiphospholipid (APL) antibody without other clinical manifestations of Antiphospholipid Syndrome. Hydroxychloroquine (HQ) is a molecule whose properties (anti-thrombotic, vascular-protective, immunomodulatory, improved glucose tolerance, lipid-lowering, anti-infectious) could be useful against mechanisms of Unexplained RM. There is no data concerning the benefit of HQ in RM in the presence or absence of antiphospholipid antibodies or any inherited thrombophilia. Administration in (Systemic Lupus erythematosus (SLE) women and for Malaria prevention provides extensive safety data during pregnancy. Oral administration makes possible treatment since the preconception period. For all of that and its low cost, hydroxychloroquine should be evaluated in RM whatever the woman thrombophilic status.

Outcome Measures

Primary Outcomes (1)

  • A live and viable birth

    In case of preterm and/or low birth weight, we define the viability by the decision to transfer the newborn to a neonatal intensive care unit

    At delivery

Secondary Outcomes (13)

  • a live and viable birth (for the subgroup analyses)

    At delivery

  • occurrence of pregnancy complications (Recurrent Miscarriage-any other premature termination of pregnancy-placental vascular disease)

    Since the beginning of pregnancy up to delivery

  • gestation time (in weeks of amenorrhea) at delivery,

    At delivery up

  • birth weight (in grams) at delivery

    At delivery

  • survival of the newborn

    At 28 days of the newborn

  • +8 more secondary outcomes

Study Arms (2)

Hydroxychloroquine

EXPERIMENTAL

The treatment will be orally administrated, at a daily dose of 400 mg of hydroxychloroquine . The treatment will be started before conception and will be stopped at the end of the tenth week of gestation or before in case of pregnancy loss.

Drug: Hydroxychloroquine

Placebo

PLACEBO COMPARATOR

A similar placebo will be orally administrated every day.

Drug: Placebo

Interventions

Hydroxychloroquine : 200 mg twice a day

Hydroxychloroquine

placebo of hydroxychloroquine

You may qualify if:

  • women aged from 18 to 38 years,

  • women who have given their informed consent

You may not qualify if:

  • ongoing pregnancy,
  • Normal pregnancy since the last miscarriage,
  • Uterine cavity abnormality,
  • Abnormal parental karyotype,
  • Antiphospholipid syndrome defined as both persistent positive antiphospholipid antibodies (40 IU or more of anticardiolipin or anti beta2 GPI IgG or IgM, and/or lupus anticoagulant) and a specific clinical setting (thrombotic or obstetrical, apart from RM)

  • Previous exposure \> 4 years to chloroquine or hydroxychloroquine
  • impossible follow up
