Treating lysosomal storage diseases before birth with enzyme therapy

Phase 1 Study of In Utero Enzyme Replacement Therapy for the Treatment of Lysosomal Storage Diseases

['FUNDING_R01'] · UNIVERSITY OF CALIFORNIA, SAN FRANCISCO · NIH-11095794

This study is exploring a new way to treat lysosomal storage diseases by giving a special enzyme therapy to babies while they are still in the womb, hoping to help them have better health and fewer problems from these conditions.

What this research studies

This research investigates a novel approach to treat lysosomal storage diseases (LSDs) by administering enzyme replacement therapy (ERT) in utero. The study aims to address the limitations of current ERT, which often cannot effectively reach the brain or prevent disease progression before birth. By infusing the therapy directly into the fetus, the researchers hope to improve survival rates and reduce the severity of these diseases. The trial will involve 10 maternal-fetal pairs, focusing on various types of LSDs to evaluate the safety and efficacy of this early intervention.

Who could benefit from this research

Good fit: Ideal candidates for this research are pregnant women carrying fetuses diagnosed with specific lysosomal storage diseases.

Not a fit: Patients who are not pregnant or whose conditions do not fall under the specified lysosomal storage diseases may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could significantly improve outcomes for infants with lysosomal storage diseases by addressing the condition before birth.

How similar studies have performed: Previous research in animal models has shown promising results for in utero enzyme replacement therapy, indicating potential for success in human trials.
