Acelyrin's financial performance in Q4 2024 showed a significant reduction in net loss and total operating expenses compared to the previous year, primarily due to lower license fees and acquired in-process research and development expenses. The company also saw a notable increase in interest income and other income, contributing to the improved financial position.

Total operating expenses decreased by 25% to $316.258 million in 2024 from $422.064 million in 2023.
Research and development expenses decreased by 33% to $238.055 million in 2024 from $355.886 million in 2023, mainly due to lower license fees.
Interest income increased by 2% to $31.209 million in 2024 from $30.555 million in 2023, and other income (expense), net, significantly increased to $36.823 million from -$423 thousand.
Acelyrin plans to re-evaluate the lonigutamab development program and will delay the initiation of the Phase 3 LONGITUDE program until the closing of the Merger. The company expects to incur significant losses and expenses as it continues product development and seeks regulatory approvals.
