Alnylam: ATTR Franchise Takes the Lead, What’s the Growth Trajectory, Competitive Risk & Valuation Reset?

$50.00 or $120.00 / year

Alnylam’s Q1 2025 results reflect a high-quality inflection point across both commercial execution and pipeline durability, with $469M in total product revenue (+28% y/y) led by 45% growth in the TTR franchise and a strong showing from AMVUTTRA. U.S. growth remains robust in hATTR-PN, while early traction in the newly approved ATTR-CM indication is promising, with formulary access achieved across >50% of top health systems within four weeks post-approval. HELIOS-B data, showing a 36% reduction in all-cause mortality and favorable functional and safety outcomes, is supporting uptake across prescriber and patient types, reinforcing AMVUTTRA’s differentiated RNAi profile. Operating leverage was evident, with $75M in non-GAAP operating income and stable 85% gross margins ahead of anticipated H2 royalty step-ups. Rare disease assets GIVLAARI and OXLUMO posted modest growth, while the pipeline showed breadth, with TRITON-CM for Nucresiran, EU/Japan regulatory progress, and early-stage programs in diabetes and hematology broadening long-term optionality. Guidance reaffirmation implies a strong CM ramp and steady execution. With $2.6B in cash and a clear visibility to platform scalability, Alnylam appears well-capitalized to navigate an increasingly competitive RNAi space. Can AMVUTTRA sustain its first-mover momentum in ATTR-CM and outpace new entrants while preserving margin discipline and pipeline leadership?
