Certolizumab to Prevent Pregnancy Complications in High-Risk Patients With APS or SLE - (IMPACT Study: IMProve Pregnancy in APS With Certolizumab Therapy)

This treatment trial evaluates the addition of an anti-tumor necrosis factor-alpha drug,
certolizumab, to usual treatment (a heparin agent and low-dose aspirin) in pregnant women
with antiphospholipid syndrome (APS) and repeatedly positive tests for lupus anticoagulant
(LAC) to determine if this regimen will improve pregnancy outcomes. All enrolled patients
will receive certolizumab, and pregnancy outcomes will be compared to those of women with APS
and repeatedly positive tests for LAC enrolled in a previous study by the investigators.

Antiphospholipid syndrome (APS) is an autoimmune disorder that occurs most commonly in women
of reproductive-age and is associated with thrombosis and adverse pregnancy outcomes (APOs),
such as fetal loss and preterm birth due to severe preeclampsia (PE) or placental
insufficiency (PI). Traditional therapy for APS during pregnancy has been a heparin agent and
low dose aspirin. However, in PROMISSE, a prospective observational study of 724 patients,
44% of pregnancies in women with APS and LAC resulted in APOs despite treatment with heparin
and low dose aspirin.

The APOs in women with APS and LAC are due to failure of adequate vascularization of the
developing placenta and subsequent inadequate blood flow to the placenta and fetus. Mouse
models of APS show that poor placental vascularization in APS is a result of inflammation in
the placenta. This inflammation leads to recruitment of neutrophils and release of more
inflammatory mediators and anti-angiogenic factors. In the mouse model tumor necrosis
factor-alpha is a critical downstream effector of abnormal placental development and fetal
damage, and tumor necrosis factor-alpha blockade during pregnancy restores angiogenic
balance, normalizes placental vascularization, and rescues pregnancies.

Based on our observations in PROMISSE and the favorable results of tumor necrosis
factor-alpha blockade in our mouse models, we hypothesize that tumor necrosis factor-alpha
blockade will significantly decrease the rate of fetal death and preterm delivery due to PE
and PI in women with APS and LAC. The study investigators aim to determine whether tumor
necrosis factor-alpha blockade during pregnancy, added to a regimen of heparin and low dose
aspirin, (1) reduces the rate of APOs in women with clinical APS and LAC, and (2) alters
angiogenic markers of poor placental vascularization. Investigators will conduct an open
label trial of certolizumab (a tumor necrosis factor-alpha inhibitor that does not cross the
placenta). The regimen of heparin and low dose aspiring is a standard of care treatment for
this patient population and is not considered part of the research intervention.

Inclusion Criteria:

- Pregnant as defined by positive test for elevated ß-HCG and having a live, appropriate
sized embryo by ultrasound, but <8 weeks gestation;

the previous 18 months and confirmed by review of medical records and core laboratory
testing;

a: The diagnosis of APS and LAC will be confirmed by one of the Co-PIs for each case
by a review of the medical records.
