Current report

Selling, general and administrative expenses for the three and six months ended June 30, 2025 increased as compared to the same periods in 2024, primarily due to higher employee compensation costs, including stock-based compensation, and increased marketing investment associated with AMVUTTRA launch in ATTR-CM.

Current report

We calculate our provision for income taxes during interim reporting periods by applying an estimate of the annual effective tax rate for the full year to pretax income or loss excluding unusual or infrequent occurring discrete items. As a result, we may experience significant fluctuations in the effective book tax rate (that is, our tax expense divided by pre-tax book income) from period to period.

Previous wording

AMVUTTRA is approved in the U.S. for the treatment of hereditary transthyretin-mediated amyloidosis, or hATTR amyloidosis, with polyneuropathy in adults, in the European Union, or EU, and the United Kingdom, or UK, for the treatment of hATTR amyloidosis in adult patients with stage 1 or stage 2 polyneuropathy, in Japan for the treatment of transthyretin, or TTR, type familial amyloidosis with polyneuropathy, and in multiple additional countries. Regulatory reviews continue in other territories. In March 2025, we announced that the United States Food and Drug Administration, or the FDA, approved our supplemental New Drug Application, or sNDA, for AMVUTTRA for the treatment of the cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis in adults to reduce cardiovascular mortality, cardiovascular hospitalizations and urgent heart failure visits. AMVUTTRA was also approved by the Brazilian Health Regulatory Agency, or ANVISA, for the treatment of ATTR amyloidosis with cardiomyopathy. In addition, vutrisiran (the generic name for AMVUTTRA) is also under regulatory review by the European Medicines Agency, or the EMA, the Japanese Health Authority, or PMDA, and the Colombian Health Authority for the treatment of ATTR amyloidosis with cardiomyopathy.

In June 2025, the European Commission, or EC, granted approval of AMVUTTRA for the treatment of wild-type or hereditary transthyretin amyloidosis in adult patients with cardiomyopathy, following a positive opinion from the Committee for Medicinal Products for Human Use of the European Medicines Agency. AMVUTTRA has also been approved by each of the Brazilian Health Regulatory Agency, or ANVISA, the Japanese Health Authority, or PMDA, the UK’s Medicines and Healthcare Products Regulatory Agency, or MHRA, and the Colombian Health Authority for the treatment of ATTR amyloidosis with cardiomyopathy.

Previous wording

In addition to our marketed products, as part of our Alnylam P 5 x25 strategy, we have multiple drivers of future growth, including the development of transformative medicines to treat prevalent disease. In addition to Leqvio, we are advancing zilebesiran, an investigational, subcutaneously administered RNAi therapeutic targeting angiotensinogen in development for the treatment of hypertension. In 2023, we entered into a Collaboration and License Agreement, or the Roche Collaboration and License Agreement, with F. Hoffmann-La Roche Ltd. and Genentech, Inc. or, collectively, Roche, pursuant to which we established a worldwide, strategic collaboration for the joint development and commercialization of zilebesiran. In March 2024, we reported positive topline results from our KARDIA-2 clinical trial, which is designed to evaluate the safety and efficacy of zilebesiran administered biannually as a concomitant therapy in patients whose blood pressure is not adequately controlled by a standard of care antihypertensive medication. In April 2024, we dosed the first patient in our KARDIA-3 Phase 2 clinical trial, which is designed to evaluate the efficacy and safety of zilebesiran as an add-on therapy in adult patients with high cardiovascular risk and uncontrolled hypertension despite treatment with two to four standard of care antihypertensive medications, and we expect to report results from the KARDIA-3 Phase 2 clinical trial in the second half of 2025. In January 2025, we announced that we expect to initiate a Phase 3 cardiovascular outcomes clinical trial in the second half of 2025.

Previous wording

We are advancing nucresiran (formerly ALN-TTRsc04), an investigational RNAi therapeutic in development for the treatment of ATTR amyloidosis. In November 2024, we announced positive results from the ongoing Phase 1 clinical trial of nucresiran in healthy volunteers. These results demonstrated that a single dose of nucresiran at 300 mg or higher resulted in mean reductions of serum TTR of greater than 90% from baseline achieved at Day 15 and were sustained through at least Day 180. We expect to initiate the TRITON-CM Phase 3 clinical trial of nucresiran in patients with ATTR amyloidosis with cardiomyopathy in the first half of 2025, and expect to initiate the TRITON-PN Phase 3 clinical trial of nucresiran in patients with hATTR polyneuropathy in late 2025.

Previous wording

We are also advancing mivelsiran (formerly ALN-APP), an investigational RNAi therapeutic targeting amyloid precursor protein in development for the treatment of Alzheimer’s disease, or AD, and cerebral amyloid angiopathy, or CAA. In October 2024, we announced positive initial results from the multiple dose portion of the Phase 1 clinical trial of mivelsiran in patients with early-onset AD. We expect to initiate a Phase 2 clinical trial of mivelsiran in patients with AD in the second half of 2025. In July 2024, we initiated dosing in the cAPPricorn-1 Phase 2 clinical trial of mivelsiran in patients with CAA.

Current wording

We are also advancing mivelsiran (formerly ALN-APP), an investigational RNAi therapeutic targeting amyloid precursor protein in development for the treatment of Alzheimer’s disease, or AD, and cerebral amyloid angiopathy, or CAA. In July 2025, we presented multiple and single dose data from the Phase 1 clinical trial of mivelsiran in patients with early-onset AD. These data demonstrated that single and multiple doses of mivelsiran were generally well tolerated and demonstrated robust, durable, dose-dependent reductions of soluble amyloid precursor protein beta (sAPPβ) in cerebrospinal fluid. Further lowering of sAPPβ was observed after administration of a second 50 mg dose of mivelsiran. We expect to initiate a Phase 2 clinical trial of mivelsiran in patients with AD in the second half of 2025. In July 2024, we initiated dosing in the cAPPricorn-1 Phase 2 clinical trial of mivelsiran in patients with CAA.

Previous wording

We have incurred significant losses since we commenced operations in 2002 and as of March 31, 2025, we had an accumulated deficit of $7.35 billion. Historically, we have generated losses principally from costs associated with research and development activities, acquiring, filing and expanding intellectual property rights, and selling, general and administrative costs. As a result of planned expenditures for research and development activities relating to our research platform, our drug development programs, including clinical trial and manufacturing costs, the continued build-out of late-stage clinical and commercial capabilities, including global commercial operations, continued management and growth of our patent portfolio, collaborations and general corporate activities, we may incur additional operating losses. While we are targeting financial self-sustainability by the end of 2025, we will continue to require significant resources over the next several years as we expand our efforts to discover, develop and commercialize RNAi therapeutics. We anticipate that our operating results will continue to fluctuate for the foreseeable future, therefore, period-to-period comparisons should not be relied upon as predictive of the results in future periods.
