To shield the fetus, link a protein to these drugs

TL;DR - A study reports that linking albumin to antibody-based medicines can reduce their passage across the placenta, potentially limiting fetal drug exposure during pregnancy.

• The approach modifies antibody-based drugs by adding albumin.
• The modification helps block placental transfer of these medicines.
• The work could inform the design of pregnancy-compatible biologic therapies.
• The provided summary does not specify the drugs tested, mechanism, or quantitative results.
