Industry Context

The approvals of AMVUTTRA and Qfitlia demonstrate the potential of RNAi technology to address unmet needs in rare and prevalent diseases. The company's collaborations with major pharmaceutical companies like Roche, Novartis, and Sanofi further validate its technology and business model.

Comparison to Industry Standards

• Alnylam's 28% revenue growth in Q1 2025 is strong compared to other biotech companies in the rare disease space.
