4Bad News, Challenges, or Points of Concern

Guidance Reduction: Lowered revenue guidance due to a better understanding of second-line demand normalization, which was initially overestimated.

Competitive Landscape: Negative outcomes from the CARDIO-TTRansform study of eplontersen raise concerns about competitive pressures, although management remains confident in TRITON-CM for nucresiran.

Market Dynamics: Potential challenges in maintaining growth rates as the market stabilizes and competition increases, particularly with generic entries anticipated in the future.

5Notable Q&A Insights

Market Dynamics: Management emphasized the importance of early diagnosis and the potential for increased patient capture in the first-line setting, with 80% of patients still untreated.

Physician Education: There is a focus on educating community physicians about the differences between silencers and stabilizers to maintain growth in first-line starts.

Impact of Competitor Data: Management does not expect significant changes in AMVUTTRA's market access due to the results of the CARDIO-TTRansform study, asserting that it does not affect AMVUTTRA's efficacy or label.

Long-term Confidence: Despite challenges, management expressed increased confidence in future growth driven by strong fundamentals and the opportunity to expand the prescriber base. Overall, Alnylam Pharmaceuticals reported strong financial results for Q2 2026, with significant growth in AMVUTTRA revenues. However, the company revised its revenue guidance downward due to normalization of second-line demand, while maintaining confidence in long-term growth prospects and strategic initiatives.
