Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 45 years
- Women only
- No healthy volunteers
- Adult
Who may be able to join
- Mothers must have anti-Ro and/or anti-La Ab documented in the NYU immunology laboratory (CLIA-approved), which utilizes an ELISA as well as reactivity on ELISA to at least one of three recombinant antigens (48La, 52Ro, 60Ro, JB laboratory).
- Mothers must have a previous child with cardiac NL, defined herein as: the presence of heart block (1st, 2nd, or 3rd degree) documented by electrocardiogram (EKG), echocardiogram, pacemaker, or statement in the medical record, and/or; presence of cardiac injury, which specifically includes autopsy evidence of a mononuclear infiltrate in the endocardium, myocardium, and pericardium and/or EFE on echocardiogram always associated with cardiac dysfunction. In PITCH, we included women with a prior child with rash; however, recent data generated from the RRNL suggest that recurrence of CHB following rash is 11%, not 18% [34]. Thus, inclusion of previous rash could lead to a falsely lowered recurrence rate, and will therefore be excluded.
- Intrauterine pregnancy ≤10 weeks.
- Mother may be taking ≤20 mg prednisone because, in our experience, CHB has developed in the presence of this dose.
- Mother may be asymptomatic, or have a rheumatic disease such as SLE or SS. Maternal health status has not been considered an influence on the development of CHB.
- Mother may or may not already be taking HCQ. This latter point was discussed with Dr. Nathalie Costedoat-Chalumeau, who has published extensively on measurement of HCQ. While it might be optimal for the mothers anticipating enrollment in the study to all have been on HCQ prior to conception, this is impractical. Some may never achieve pregnancy and not want to take HCQ unless they conceive (especially those asymptomatic). On the other hand, women with SLE are likely to already be on HCQ and it would limit enrollment to exclude these patients if all must initiate HCQ only at enrollment in the first trimester. Although the accepted dogma is that HCQ requires several months for maximal efficacy in treating rheumatic disease, it is unknown whether this would apply to transplacental passage or fetal levels (which are impossible to measure). Dr. Costedoat-Chalumeau suggests that HCQ is probably a three compartment model which includes the circulation, tissues and cells. In the circulation, the half life is approximately 7 days and in the tissues, it is 40 days. In Dr. Costedoat-Chalumeau's experience, steady state blood levels of HCQ are achieved in 4-6 weeks. Thus, dosing the mother no later than 10 weeks gestation should provide sufficient fetal exposure before the vulnerable period of CHB which is generally accepted to span 18-24 wks. Furthermore, the placenta has to be formed for HCQ to gain access to the fetus and it may be effective quickly for the biology we are considering.
Who cannot join
- Mother does not have Ab to Ro or La.
- Identification of any of the following structural lesions considered causal for CHB, i.e., those that could account for block because of fibrous disruption between the atrium and AV node or due to absence of the penetrating bundles of the AV node:
- atrioventricular septal defects;
- b) single ventricle
- c) developmental tricuspid valve disease;
- d) L-transposition of the great arteries;
- e) heterotaxia.
- Mother is taking any glucocorticoids. Although unlikely to be preventative, the use of steroids may confound the interpretation of results. The final point of intense discussion centered around whether another exclusion should be the use of HCQ in the first pregnancy in which CHB occurred. While one could argue that in these mothers HCQ was not effective and perhaps will not be again, this assumption remains speculative and thus prior absence of efficacy of HCQ will not constitute an exclusion criteria.

About this study
Women with antibodies to proteins called SSA/Ro and or SSB/La face a 2% chance of having a child with a life threatening heart condition regardless of whether they have very active lupus, are in remission, or have only vague symptoms. This heart problem is referred to as congenital heart block (the most serious being third degree complete block) and represents damage thought to be caused by these autoantibodies. The heart beats abnormally slowly and almost all children require permanent pacemakers before the age of 20. Importantly, women who have had one child with heart block have a ten-fold higher risk of having another child with the same heart condition. Unfortunately, even close monitoring by special techniques during pregnancy does not reverse complete heart block once it is observed. Thus, treatments aimed at prevention are critical. This study will evaluate for the first time whether hydroxychloroquine, a drug used by many patients with SLE, prevents the development of this heart condition. Data from laboratory experiments suggests that this drug, which crosses the placenta, may decrease the inflammation initiated by the passage of anti-Ro antibodies to the fetus. The study uses a Simon's 2-Stage design, and plans to enroll 19 patients in Stage 1 and 35 patients in Stage 2 if Stage 1 is successful. Patients can already be on hydroxychloroquine or will be started as soon as pregnancy is confirmed. The hope is that fewer than 3 cases of heart block will occur in Stage 1, and fewer than 6 cases will occur out of all 54 patients if Stage 2 is reached. The results of this study are expected to become an integral part of the counseling of women with anti-Ro/La antibodies who are considering pregnancy.
Read the detailed description
One of the strongest clinical associations with autoantibodies directed to components of the Ro/La ribonucleoprotein complex is the development of congenital heart block (CHB) in an offspring, an alarming prospect facing 2% of primigravid mothers with these reactivities. The risk is 10-fold higher in women who have had a previously affected child. Despite the attempt of large multicenter studies to forestall disease by serial in utero monitoring, irreversible block and extensive myocardial injury have been documented within 7 days of a normal rhythm and PR interval. CHB is associated with a substantial mortality and morbidity. Two recent prospective studies (20 mothers from U.S. and 15 from Europe) utilizing an identical protocol of IVIG at replacement doses demonstrated 1) this intervention does not prevent the recurrence of CHB 2) the recurrence rate of 17-18% is robust 3) recruitment of patients is feasible. During the time period of the IVIG trials, basic science exploring the pathogenesis of disease supported the notion that Toll Like Receptor (TLR) signaling following ligation of ssRNA (hY3) complexed to the Ro protein contributes to fibrosis. This observation led to in vitro studies addressing inhibition of endosomal acidification by chloroquine and subsequent translation to patients by evaluating the use of hydroxychloroquine (HCQ) in an extensive retrospective chart review. The combined data suggest efficacy of HCQ. Accordingly, the goal of this study is to: To determine whether hydroxychloroquine use during pregnancy prevents CHB in a high risk population. The trial is open-label and employs the Simon's 2-stage optimal design to allow for early stopping due to absence of treatment efficacy. The first stage requires 19 subjects. Despite the rarity of disease and the requirement of a previous CHB child, based on the US Research Registry for Neonatal Lupus, this proposal is feasible. If 3 or more mothers have a child with 2nd or 3rd degree CHB, the study is terminated after the first stage. If this does not occur, funds will be sought to enroll an additional 35 mothers in the second stage for a total of 54 subjects. Treatment will be considered efficacious if fewer than 6 mothers of 54 have a child with advanced CHB. With this design, the study has 90% power to conclude that hydroxychloroquine is preventive if the true recurrence rate with the treatment is 5%. In addition, the probability of rejecting the treatment for further study is 95% if the true recurrence rate is 18%. Serial echocardiograms (monitor PR interval) and blood drawing (IFNƒÑƒnsignatures, antibody titers) will be included in the protocol. The results of this study are expected to become an integral part of the counseling of women with anti-SSA/Ro-SSB/La antibodies who are considering pregnancy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Also called Plaquenil
Nineteen women meeting eligibility criteria will receive 400mg per day of HCQ beginning as soon as pregnancy is established and informed consent obtained. Mothers already on HCQ will remain on 400mg, or escalate to 400mg if on 200mg. Hydroxychloroquine is taken in 200mg pill form - 400mg = 2 200mg pills.
| Study group | Role | What they receive |
|---|---|---|
| Pregnant women with previous child with cardiac neonatal lupus | Experimental | 400 mg/day Hydroxychloroquine Receives: Drug: Hydroxychloroquine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Recurrence of Advanced Heart Block
Echocardiogram reveals 2nd or 3rd degree AV block
Measured: After enrollment at 16-18 weeks gestation, then weekly until 26 weeks, biweekly to 34 weeks, at birth (approximately 9 months), and at one year follow up (approximately 21 months from enrollment)
Secondary outcomes (8)
Prolonged PR Interval (>150msec)
EKG at birth must confirm 1st degree AV block. It is also possible that a fetus developing 1st degree block on study medication might have developed more advanced block in the absence of study medication.
Measured: After enrollment at 16-18 weeks gestation, then weekly until 26 weeks, biweekly to 34 weeks, at birth (approximately 9 months), and at one year follow up (approximately 21 months from enrollment)
Any Sign of Myocardial Injury, Without Change in Cardiac Rate or Rhythm
- shortening fraction <28% = 2 SD below normal mean or qualitatively reduced systolic function; b) cardio-thoracic ratio >0.33; c) hydropic changes; d) moderate/severe tricuspid regurgitation.
Measured: After enrollment at 16-18 weeks gestation, then weekly until 26 weeks, biweekly to 34 weeks, at birth (approximately 9 months), and at one year follow up (approximately 21 months from enrollment)
Echocardiographic Densities Consistent With EFE Confirmed Postnatally
(see title)
Measured: After enrollment at 16-18 weeks gestation, then weekly until 26 weeks, biweekly to 34 weeks, at birth (approximately 9 months), and at one year follow up (approximately 21 months from enrollment)
Fetal Death Not Related to Cardiac Dysfunction
An autopsy with full evaluation of the heart will be encouraged but cannot be mandated. If AV block or evidence of a cardiomyopathy can be "proven," then these will provide the basis for final categorization. If not possible, the death will not be considered a recurrence rate but will be reported.
Measured: Up to 9 months
Cutaneous Neonatal Lupus
Measured: Up to 15 months (at birth - 9 months, and 6 months thereafter)
Prematurity
(gestational age <37 weeks at birth)
Measured: At birth (approximately 9 months)
Birth Weight <10% in the Context of Gestational Age
Measured: At birth (approximately 9 months)
Abnormal Fluid Collection
Measured: At birth (approximately 9 months)

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Hydroxychloroquine in people with Congenital Heart Block and Neonatal Lupus, run by NYU Langone Health at 1 site in United States.
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 6 inclusion and 8 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: finished, as of the sponsor's last update on 25 Feb 2021. 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 United States. 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?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 16 Mar 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Recurrence of Advanced Heart Block (time frame: After enrollment at 16-18 weeks gestation, then weekly until 26 weeks, biweekly to 34 weeks, at birth (approximately 9 months), and at one year follow up (approximately 21 months from enrollment)). 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 NCT01379573, which also lists 2 linked publications.
