Authors of approved LBA applications will be notified and advised on the processes for submitting final data by November 7, 2025. Authors of abstracts not being accepted for LBA submissions will be notified and given 5 days to submit all available data before the abstract is re-classified as a regular abstract and included in the regular abstract review and scheduling process.
