Alnylam Pharmaceuticals (NASDAQ: ALNY), headquartered in Cambridge, Massachusetts, is the pioneering RNA interference (RNAi) therapeutics company that turned an academic biology finding into a commercial-stage drug class. The commercial franchise is anchored in cardiovascular and rare-disease indications, with Amvuttra (vutrisiran) as the lead product for transthyretin (ATTR) amyloidosis in both hereditary polyneuropathy and cardiomyopathy indications.
On this site, Alnylam appears primarily through its obesity pipeline entry and its peptide-adjacent modality intersections. The ALN-6222 first-in-human Phase 1 obesity trial (NCT07624071) opened enrollment in July 2026 as a randomized, double-blind, placebo-controlled, single-ascending-dose study of an undisclosed-target subcutaneous siRNA in adults with BMI 30-40 kg/m² and HbA1c below 6.5% at a single site in Mount Royal, Canada, targeting completion in December 2027. A second obesity siRNA, ALN-2232, is expected to produce Phase 1 readout in the second half of 2026. The Alnylam obesity pipeline targets include inhibin subunit beta E (INHBE) in liver and activin receptor type 1C (ACVR1C) in adipose tissue.
The Alnylam-PeptiDream collaboration first announced in 2021 produced a December 2025 preclinical milestone demonstrating peptide-ligand-mediated targeted siRNA delivery to specific extrahepatic tissues, laying groundwork for a peptide-siRNA conjugate platform beyond the liver.

Alnylam Pharmaceuticals (NASDAQ: ALNY) reported Q2 2026 earnings Thursday July 30, 2026 before market open. Amvuttra (vutrisiran) quarterly revenue crossed $1 billion for the first time at $1.012 billion (approximately a $4 billion annualized run rate approximately 15 months after the ATTR-CM launch). Total Q2 revenue reached $1.29 billion (+67% year-over-year) but fell short of the $1.31 billion analyst consensus. Net product revenues were $1.17 billion (+74% YoY) versus the $1.22 billion estimate. GAAP diluted EPS was $1.21 versus the $1.49 estimate. Full-year 2026 TTR product sales guidance was revised down to $4.2-4.5 billion to reflect normalized second-line volume after the initial pent-up demand from patients waiting for a new therapy. Pipeline updates: Alnylam expects to announce clinical data from Phase 1 and Phase 2 trials of ALN-6400 in healthy volunteers and patients with hereditary hemorrhagic telangiectasia (HHT) in second-half 2026, plus results from the Phase 1 trial of ALN-2232 (Alnylam's second obesity-track siRNA) in the same second-half window. The ALN-6222 obesity siRNA Phase 1 trial (NCT07624071) opened enrollment in July 2026 with a first-in-human single-ascending-dose design in adults with BMI 30-40 kg/m² at a single site in Mount Royal, Canada through December 2027.
Alnylam Pharmaceuticals (NASDAQ: ALNY) reports Q2 2026 earnings Thursday July 30, 2026 before market open with an 8:30 AM ET conference call. Wall Street consensus estimates: EPS of $2.05 (+540.6% year-over-year) and revenue of $1.32 billion (+70.4% year-over-year), reflecting the continued commercial ramp of Amvuttra (vutrisiran) across both hereditary transthyretin amyloid polyneuropathy (hATTR-PN) and hereditary transthyretin amyloid cardiomyopathy (hATTR-CM) after the Q1 2026 Amvuttra revenue of $889.9 million (+187% YoY). Analyst focus areas beyond the base-business ramp include: the ALN-6222 first-in-human Phase 1 obesity siRNA program (NCT07624071) that opened enrollment in July 2026 as a randomized double-blind placebo-controlled single-ascending-dose study of an undisclosed-target subcutaneous siRNA in adults with BMI 30-40 kg/m²; the ALN-2232 Phase 1 obesity program (Alnylam's second obesity-track siRNA) with Phase 1 readout expected in the second half of 2026; the Alnylam-PeptiDream peptide-siRNA conjugate extrahepatic delivery platform milestone announced December 2025; and the broader Alnylam 2030 strategy launch positioning beyond the Amvuttra franchise.
Alnylam Pharmaceuticals (NASDAQ: ALNY) reports Q2 2026 earnings Thursday July 30, 2026 before market open. Analyst focus areas include the new ALN-6222 investigational subcutaneous siRNA obesity Phase 1 trial (NCT07624071, first-in-human single-ascending-dose randomized double-blind placebo-controlled design enrolling approximately 88 adults with BMI 30 to less than 40 kg/m² and HbA1c below 6.5% at a single site in Mount Royal, Canada through December 2027; molecular target of ALN-6222 has not been publicly disclosed). Also under focus: the Phase 1 ALN-2232 program (Alnylam's second obesity-track siRNA, with a Phase 1 readout expected in the second half of 2026), the Alnylam-PeptiDream peptide-siRNA conjugate extrahepatic delivery platform milestone announced December 2025 (demonstrating peptide-ligand-mediated targeted siRNA delivery to specific extrahepatic tissues), and the broader Alnylam 2030 strategy launch positioning beyond the Amvuttra (vutrisiran) transthyretin amyloidosis franchise. Alnylam's obesity pipeline is programmed against inhibin subunit beta E (INHBE) in liver and activin receptor type 1C (ACVR1C) in adipose tissue, both nucleic-acid modality targets that are distinct from GLP-1 agonism.
Alnylam Pharmaceuticals (NASDAQ: ALNY) confirmed a first-in-human Phase 1 trial of ALN-6222, an investigational subcutaneous siRNA therapeutic in adults with obesity, in a July 22 filing update on ClinicalTrials.gov (NCT07624071). The randomized, double-blind, placebo-controlled, single ascending dose study will enroll approximately 88 participants with a BMI of 30 to less than 40 kg/m² and an HbA1c below 6.5% (excluding participants with diabetes). The primary endpoints are safety and pharmacodynamics; secondary endpoints include changes in body weight and metabolic markers. The molecular target of ALN-6222 has not been publicly disclosed. The trial is set to run through December 2027 at a single site in Mount Royal, Canada. ALN-6222 marks Alnylam's first clinical-stage entry into the obesity therapeutic area, joining a broader wave of nucleic-acid, peptide, and peptide-fusion modalities entering the space beyond the GLP-1 incumbents (Wegovy, Ozempic, Mounjaro, Zepbound) and the Alnylam-PeptiDream peptide-siRNA conjugate collaboration announced in 2021. Alnylam separately reports Q2 2026 earnings later this week and is expected to discuss the ALN-6222 program on the call.
On June 4, 2026, Alnylam Pharmaceuticals announced a partnership worth up to $2 billion with Inceptive, the AI biotech focused on programmable RNA and peptide medicines, to apply machine learning to peptide discovery. The deal is the second major back-loaded peptide-AI collaboration to land in the same week, following Regeneron's expanded Parabilis tie-up tied to Phase 3 LAG-3 setbacks.
