Current report
•Eligible people with CF in England, Ireland, Germany, Denmark and Northern Ireland have reimbursed access to ALYFTREK, and we are working to secure access for eligible patients in additional countries.
Current report
•In September, we secured reimbursement for CASGEVY for people with SCD and TDT in Italy. Italy has the largest population of people living with TDT in Europe, with approximately 5,000 people 12 years of age and older with TDT and approximately 2,300 people 12 years of age and older with SCD.
Current report
•Globally, since launch through September 30, 2025, approximately 165 people with SCD or TDT have had their first cell collection for CASGEVY, including 50 people in the third quarter of 2025, and 39 people with SCD or TDT have received infusions of CASGEVY, including 10 people infused in the third quarter of 2025.
Current report
•In October, we completed the pivotal clinical trial of TRIKAFTA in children 12 months to less than 24 months of age. The data showed that TRIKAFTA was generally safe and well-tolerated, consistent with the established safety profile. We expect to submit for approval in this age group with global regulators in the first half of 2026.
Current report
•We have completed enrollment in a global trial evaluating ALYFTREK in children 2 to 5 years of age. In this pivotal clinical trial, approximately 65 children will receive ALYFTREK for 24 weeks. We expect to share data from this clinical trial in the first half of 2026.
Current report
•The FDA has granted a rolling review to the Biologics Licensing Application (“BLA”) submission for povetacicept for the treatment of IgAN. We have completed enrollment of the interim analysis cohort for potential accelerated approval in the U.S., and we have completed the clinical trials to support the launch of povetacicept for monthly, at-home self-administration with an autoinjector. We expect to submit the first module of the IgAN BLA to the FDA before the end of 2025, and we expect to complete the full BLA submission in the first half of 2026 for potential accelerated approval in the U.S. In addition, we have completed full enrollment of the Phase 3 clinical trial evaluating IgAN.
Current report
•We have initiated the Phase 2/3 pivotal clinical trial of povetacicept for the treatment of people with pMN.

Previous report
•ALYFTREK is approved by the European Commission for the treatment of people with CF 6 years of age and older who have at least one F508del mutation or another responsive mutation in the CFTR gene. Eligible patients in Germany and Denmark have access to ALYFTREK, and we expect eligible patients in Ireland will have access in the third quarter of 2025. We will continue to work with reimbursement bodies across additional E.U. member states to ensure access for all eligible patients as quickly as possible. In addition, we have entered into a reimbursement agreement with the National Health Service (“NHS”) England for eligible CF patients to access ALYFTREK.
Previous report
•Through reimbursement agreements, we have secured access to CASGEVY for eligible SCD and TDT patients in 10 countries. Countries with recent reimbursement agreements include Northern Ireland, Scotland and Denmark. We will continue to work with government and reimbursement authorities globally to secure access for eligible patients.
Previous report
•We have met our goal of activating more than 75 authorized treatment centers. Since launch through the end of the second quarter of 2025, approximately 115 patients have had their first cell collection, and 29 patients have received infusions of CASGEVY, including 16 patients infused in the second quarter of 2025.
Previous report
•We are completing Phase 3 clinical trials in younger age groups to expand the TRIKAFTA/KAFTRIO and ALYFTREK labels and to enable earlier treatment of children with CF. We have completed enrollment in a global trial evaluating ALYFTREK in children 2 to 5 years of age.
Previous report
•In collaboration with Moderna, Inc. (“Moderna”), we are developing VX-522, a nebulized CFTR mRNA therapy for the treatment of people with CF who do not produce full-length CFTR protein. The Independent Data Monitoring Committee has completed its review of VX-522, and endorsed restart of the Phase 1/2 clinical trial evaluating VX-522. We expect to resume dosing in the multiple ascending dose portion of this trial in the near term.
Previous report
Acute Pain
Previous report
•We announced results from the Phase 2 placebo-controlled dose-ranging clinical trial evaluating the safety and efficacy of VX-993, an investigational selective NaV1.8 pain signal inhibitor, for the treatment of acute pain following bunionectomy surgery. Treatment with VX-993 did not result in a statistically significant improvement on the primary endpoint of the time-weighted sum of the pain intensity difference from 0 to 48 hours (SPID48) compared to placebo. VX-993 was generally safe and well-tolerated. Based on these results, we will not further advance VX-993 as monotherapy in acute pain.
Previous report
•As part of an End of Phase 2 discussion with the FDA, the FDA indicated that they do not see a path to a broad peripheral neuropathic pain label at this time. As such, we will not initiate a Phase 3 lumbosacral radiculopathy clinical trial. We will prioritize diabetic peripheral neuropathy as the first peripheral neuropathic pain indication, and we expect to begin a second Phase 3 clinical trial evaluating suzetrigine in diabetic peripheral neuropathy in the near term. We expect to complete enrollment in both Phase 3 clinical trials in diabetic peripheral neuropathy by the end of 2026. We plan to continue to work with the FDA to expand the diabetic peripheral neuropathy indication over time to include additional neuropathic pain conditions and assess potential pathways to secure a broad peripheral neuropathic pain label.
Previous report
•The global Phase 3 RAINIER trial evaluating povetacicept in people with IgAN completed enrollment of the interim analysis cohort in the second quarter. The interim analysis will be conducted once this cohort reaches 36 weeks of treatment, with the potential to file for Accelerated Approval in the U.S. in the first half of 2026, if results are supportive. We expect to complete enrollment in the full clinical trial in 2025. Clinical trials to support the launch of povetacicept for at-home self-administration are underway.
Previous report
•Based on the strength of the Phase 2 results in the RUBY-3 clinical trial, we completed the End of Phase 2 meeting with the FDA and reached agreement with the FDA on the pivotal development program in pMN. We expect to initiate the Phase 2/3 trial evaluating povetacicept in people with pMN by the end of 2025.
Previous report
•We have prioritized generalized myasthenia gravis (“gMG”) andwarm autoimmune hemolytic anemia (“wAIHA”) as the next potential indications for povetacicept. Other RUBY-3 and RUBY-4 indications have been deprioritized. In the U.S. and Europe, we believe there are approximately 300,000 people diagnosed with IgAN, approximately 150,000 people diagnosed with pMN, approximately 175,000 people diagnosed with gMG, and approximately 35,000 people diagnosed with primary wAIHA.
Previous report
•In June, we entered into an exclusive collaboration and license agreement with Ono Pharmaceutical Co., Ltd. for the development and commercialization of povetacicept in Japan and South Korea. This partnership further expands upon the geographic expansion momentum started through a partnership with Zai Lab announced in January.
Previous report
In the second quarter and first half of 2025, “Other revenues” were $20.7 million and $30.7 million, respectively. In the second quarter of 2025, Other revenues included a $20.6 million upfront payment received from our collaboration agreement with Ono. In the first half of 2025, Other revenues also included a $10.0 million upfront payment received from our collaboration agreement with Zai.
Previous report
Other income (expense), net was income of $13.2 million and expense of $23.1 million in the second quarter of 2025 and 2024, respectively, and expenses of $4.4 million and $54.3 million in the first half of 2025 and 2024, respectively. These amounts primarily related to net unrealized gains or losses resulting from changes in the fair value of certain of our strategic equity investments, which consist of investments in our collaborators that may be public or privately-held companies. To the extent that we continue to hold strategic equity investments in publicly traded biotechnology companies, we expect that our other income (expense), net will continue to fluctuate in future periods due to the volatility in the stock prices of these companies that impacts the fair value of our investments. As of June 30, 2025, the fair value of our investments in publicly traded companies was $27.9 million.
Previous report
As of June 30, 2025, total working capital was $6.3 billion, which represented an increase of $257.7 million, or 4%, compared to December 31, 2024, primarily due to increased cash and cash equivalents resulting from our operations and increased inventories following the commercial launches of ALYFTREK and JOURNAVX.

Previous wording
In the first half of 2025, our net product revenues came primarily from the sale of our medicines for the treatment of CF. Our CF strategy involves continuing to develop and obtain approval and reimbursement for treatment regimens that will provide benefits to all people with CF and increasing the number of people with CF eligible and able to receive our medicines. We are continuing to progress commercialization of CASGEVY, which has received marketing approvals in the U.S. and across multiple geographies, including countries in Europe and the Middle East, for the treatment of SCD and TDT. In addition, we have begun our commercial launch of JOURNAVX for the treatment of acute pain, which received marketing approval in the U.S. in January 2025. We also continue to advance our pipeline of product candidates for the treatment of serious diseases outside of CF, SCD, TDT, and acute pain.

Previous wording
In the U.S., we have worked successfully with third-party payors to promptly obtain appropriate levels of reimbursement for our CF medicines. In addition, we are working with U.S. government and commercial payors with respect to CASGEVY and JOURNAVX. We anticipate broad access with government and commercial payors for CASGEVY in the U.S., and we have recently entered into multiple agreements with government and commercial health insurance providers to provide such access. For JOURNAVX in the U.S., we have been working with government and commercial payors pre- and post-approval to support rapid and broad access. We plan to continue to engage in discussions with numerous commercial insurers and managed health care organizations, along with government health programs that are typically managed by authorities in the individual states, to ensure that payors recognize the significant benefits that all our therapies provide and provide patients with appropriate levels of access to our medicines and therapies now and in the future. We cannot, however, predict how changes in the law, including through the Inflation Reduction Act of 2022 and passage of state laws (e.g., transparency laws and prescription drug affordability boards), will affect our ability to negotiate successfully with third-party payors and distribute our products. In addition, federal and state governments in the U.S. continue to consider policies to lower prescription drug costs. The logistics of such initiatives continue to be discussed, and we cannot anticipate how these actions, if enacted, may impact our revenues and our business. Similarly, in ex-U.S. markets, we seek government reimbursement for our medicines on a country-by-country or region-by-region basis, as required. This is necessary for each new medicine, as well as for label expansions for our current medicines. We are working with ex-U.S. payors with respect to CASGEVY, and we are pursuing long-term reimbursement agreements. We have secured reimbursed access for people with SCD or TDT across multiple geographies, including countries in Europe and the Middle East. We expect to continue to focus significant resources to expand and maintain reimbursement for our CF medicines, CASGEVY, JOURNAVX, and, ultimately, our pipeline therapies, in U.S. and ex-U.S. markets.

Previous wording
Generally, when we in-license a technology or product candidate, we make upfront payments to the collaborator, assume the costs of the program and/or agree to make contingent payments, which could consist of milestone, royalty and option payments. Most of these collaboration payments are expensed as AIPR&D, including a $75.0 million milestone due to Entrada in the first quarter of 2024. These payments were expensed to AIPR&D because they were primarily attributable to acquired in-process research and development for which there was no alternative future use. However, depending on many factors, including the structure of the collaboration, the stage of development of the acquired technology, the significance of the in-licensed product candidate to the collaborator’s operations and the other activities in which our collaborators are engaged, the accounting for these transactions can vary significantly. We expect to continue to identify and evaluate collaboration and licensing opportunities that may be similar to or different from the collaborations and licenses that we have engaged in previously.

Previous wording
In the second quarter and first half of 2025, our net product revenues increased 13% and 11% in the U.S., as compared to the second quarter and first half of 2024, respectively, due to higher net realized pricing and continued strong patient demand. In the second quarter of 2025, our ex-U.S. net product revenues increased 8% as compared to the second quarter of 2024, primarily due to strong performance across multiple geographies. In the first half of 2025, our ex-U.S. net product revenues increased 1%, as compared to the first half of 2024, primarily due to an expected decline in product revenues in Russia, where we are continuing to experience a violation of our intellectual property rights.

In the third quarter and nine months ended September 30, 2025, our net product revenues increased 15% and 13% in the U.S., as compared to the third quarter and nine months ended September 30, 2024, respectively, due to continued strong patient demand, new patient initiations and higher net realized pricing. In the third quarter and nine months ended September 30, 2025, our ex-U.S. net product revenues increased 4% and 2%, respectively, as compared to the third quarter and nine months ended September 30, 2024, primarily due to solid performance across multiple geographies, partially offset by an expected decline in product revenues in Russia, where we are continuing to experience a violation of our intellectual property rights.

Our cost of sales primarily consists of third-party royalties payable on net sales of our CF products as well as the cost of producing inventories. Pursuant to our agreement with the Cystic Fibrosis Foundation, our tiered third-party royalties on sales of ALYFTREK, TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, KALYDECO, and ORKAMBI, calculated as a percentage of net sales, range from the single digits to the sub-teens, with lower royalties on sales of ALYFTREK and TRIKAFTA/KAFTRIO than for our other products. The royalty burden associated with TRIKAFTA is 9.33% and the royalty burden associated with ALYFTREK is 4%. As previously disclosed, the third party to whom the Cystic Fibrosis Foundation has assigned its ALYFTREK royalty rights has made public statements that they believe the ALYFTREK royalty burden is in the high single-digits. We believe that these statements are inconsistent with the plain terms of our agreement with the Cystic Fibrosis Foundation and would not survive close scrutiny. Following our earnings call on August 4, 2025, the third party requested that we engage in discussions to resolve this disagreement, which engagement is required by the agreement.

The royalty burden associated with TRIKAFTA is 9.33% and our position is that the royalty burden associated with ALYFTREK is 4%. On October 10, 2025, Royalty Pharma plc (“RP”), the third party to whom the CFF assigned its rights (and the CFF, which remains a party to the CFF Agreement), initiated a confidential arbitration alleging the royalty burden on ALYFTREK is approximately 8%. RP is seeking a declaratory judgment regarding the royalty burden on ALYFTREK as well as alleged unpaid royalties and other alleged damages available under the CFF Agreement or applicable law, costs, expenses, attorneys’ fees, and interest.
