PEARL (PrEnAtal Enzyme Replacement Therapy for Lysosomal Storage Disorders)
University of California, San Francisco
Summary
For detailed information, please view our study website: https://pearltrial.ucsf.edu/ The investigators aims to determine the the maternal and fetal safety and feasibility of in utero fetal enzyme replacement therapy in fetuses with Lysosomal Storage Diseases.
Description
Because fetuses with these LSDs are at increased risk of serious perinatal morbidity and mortality, particularly in the setting of Non-Immune Hydrops Fetalis (NIHF), the administration of the approved enzyme therapy in utero has the potential to significantly improve outcomes for affected fetuses. The perinatal death rate associated with NIHF ranges from 30 to 75%, so development of an in utero approach to treatment could be of significant benefit. The in utero period has been shown to be a time of relative fetal tolerance to immune stimuli, and this tolerance may lead to improved response to…

- Healthy volunteers
- No
Inclusion Criteria: * Live male or female fetuses at 18 0/7 weeks to 34 6/7 weeks gestation * Diagnosis of one of the 8 included LSDs in utero by genetic or enzymatic analyses performed on amniotic fluid, fetal blood, placental tissue, or other samples through chorionic villus sampling (CVS), amniocentesis, cordocentesis, cell free fetal DNA, or other procedures. In the event that parents are identified as genetic carriers for a LSD, diagnostic testing for the fetus would be performed to confirm the diagnosis * Pregnant women age 18 years to 50 years, carrying a live male or female fetus at 1…
