What this trial studies
This observational program aims to evaluate the safety of mavacamten exposure during pregnancy and breastfeeding by assessing maternal, fetal, and infant outcomes. Participants must have received at least one dose of mavacamten at any time from four months prior to conception through the outcome of the pregnancy or during breastfeeding. The study will gather data on the health effects for both mothers and infants to ensure safety and inform future use of the medication in these populations.
Why it matters
Potential benefit: If successful, this program could provide critical safety information for mothers and infants exposed to mavacamten during pregnancy and breastfeeding.
How similar studies have gone: While this specific approach is observational and may not have been extensively tested, similar studies assessing medication safety during pregnancy have shown the importance of monitoring outcomes.
