Product revenue of $2.49 billion, a 14% increase compared to Q2 2022 Company raises full year 2023 product revenue guidance to $9.7 to $9.8 billion FDA has accepted the exa-cel BLAs in both severe sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT); Priority Review granted for SCD with PDUFA date of December 8, 2023 Pipeline continues to advance with multiple near-term clinical milestones BOSTON--(BUSINESS WIRE)-- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today reported consolidated financial results for the second quarter ended June 30, 2023 and updated its full year 2023 financial guidance. “The second quarter of 2023 marked another period of strong progress across our business. We are reaching more patients globally with our cystic fibrosis medicines, advancing our late-stage clinical programs and making rapid progress across our research and development pipeline of transformative medicines,” said Reshma Kewalramani, M.D., Chief Executive Officer and President of Vertex. “In the second half of the year, we look forward to expanding our leadership in CF; continuing to prepare for several near-term potential launches, starting with exa-cel; and completing major Phase 3 trials including VX-548 in acute pain and the vanzacaftor triple in cystic fibrosis.” Second Quarter 2023 Results Product revenue increased 14% to $2.49 billion compared to the second quarter of 2022, primarily driven by the strong uptake of TRIKAFTA/KAFTRIO in multiple countries internationally and continued performance of TRIKAFTA in the U.S., including the launch in children with CF 2 to 5 years of age. Net product revenue in the second quarter of 2023 increased 7% to $1.51 billion in the U.S. and increased 26% to $985 million outside the U.S., compared to the second quarter of 2022. Combined GAAP and Non-GAAP R&D, Acquired IPR&D and SG&A expenses were $1.2 billion and $1.0 billion, respectively, compared to $877 million and $750 million, respectively, in the second quarter of 2022. The increases were due to increased investment in support of multiple programs that have advanced in mid- and late-stage clinical development, increased acquired IPR&D expenses, and the costs to support launches of Vertex's therapies globally. GAAP effective tax rate was 21.2% compared to 20.9% for the second quarter of 2022. Non-GAAP effective tax rate was 21.0% compared to 21.8% for the second quarter of 2022. Please refer to Note 1 for further details on our GAAP to Non-GAAP tax adjustments. GAAP and Non-GAAP net income increased by 13% and 9%, respectively, compared to the second quarter of 2022, primarily driven by strong revenue growth and increased interest income partially offset by increased investment in our mid- and late-stage clinical pipeline, increased acquired IPR&D expenses, and the costs to support launches of Vertex’s therapies globally. Cash, cash equivalents and total marketable securities as of June 30, 2023 were $12.6 billion, compared to $10.9 billion as of December 31, 2022. The increase was primarily driven by strong revenue growth and operating cash flow, partially offset by our payments to Entrada Therapeutics, CRISPR Therapeutics and other collaboration partners, repurchases of our common stock pursuant to our share repurchase program, and income tax payments. Full Year 2023 Financial Guidance Vertex is raising its full year 2023 CF product revenue guidance to $9.7 to $9.8 billion, from $9.55 to $9.7 billion previously. The increase reflects the expected full-year impact of the strong uptake of TRIKAFTA/KAFTRIO in multiple countries internationally and continued performance of TRIKAFTA in the U.S. This guidance includes an approximately 150-basis-point negative impact from changes in foreign currency rates, inclusive of our foreign exchange risk management program. Vertex is also increasing full year 2023 combined GAAP and non-GAAP R&D, Acquired IPR&D and SG&A expense guidance. The increase accounts for higher acquired IPR&D expenses incurred year-to-date, including a $70 million milestone payment to CRISPR Therapeutics. Vertex’s financial guidance is summarized below: Current FY 2023 Previous FY 2023 CF product revenues $9.7 to $9.8 billion $9.55 to $9.7 billion Combined GAAP R&D, Acquired IPR&D and SG&A expenses (2) $4.55 to $4.8 billion $4.35 to $4.6 billion Combined Non-GAAP R&D, Acquired IPR&D and SG&A expenses (2) $4.1 to $4.2 billion $3.9 to $4.0 billion Non-GAAP effective tax rate Unchanged 21% to 22% Key Business Highlights Cystic Fibrosis (CF) Marketed Products Vertex anticipates the number of CF patients taking our medicines will continue to grow, including through new approvals and reimbursement for the treatment of younger patients. Recent progress includes: Approval from the European Commission for the use of ORKAMBI in children with CF ages 1 to <2 years old who have two copies of the F508del mutation in the CFTR gene. With this approval, approximately 300 children with CF are eligible for the first time for a medicine that can treat the underlying cause of their disease. At the European Cystic Fibrosis Society’s (ECFS) European Cystic Fibrosis Conference in June, Vertex presented interim results from the largest real-world study of TRIKAFTA/KAFTRIO, which showed sustained improvement in lung function, reduction in pulmonary exacerbations frequency and lower rates of lung transplant and death for people with CF. Approval from the U.S. Food and Drug Administration (FDA) for the use of KALYDECO in children with CF from 1 month to <4 months of age. This approval represents the first and only CFTR modulator approved for this age group. Vertex also submitted Marketing Authorization Applications (MAAs) to the European Medicines Agency (EMA), the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom, and Health Canada for the use of KALYDECO in children with CF from 1 month to <4 months of age. Approval from the FDA for the use of TRIKAFTA in children 2 to 5 years of age with at least one F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene or a mutation in the CFTR gene that is responsive to TRIKAFTA. With this approval, approximately 900 children are eligible for TRIKAFTA for the first time. Vertex also completed regulatory submissions with the EMA, the MHRA, Health Canada, and the Therapeutic Goods Administration in Australia for the use of KAFTRIO/TRIKAFTA in children 2 to 5 years of age. Potential Near-Term Launch Opportunities Vertex is preparing for the following near-term potential new product launches: Exagamglogene autotemcel (exa-cel) in SCD and TDT: Exa-cel is a precise non-viral ex vivo CRISPR gene-editing therapy, which is being developed in collaboration with CRISPR Therapeutics as a potential functional cure for SCD and TDT. The FDA accepted the Biologics License Applications (BLAs) for exa-cel and assigned Prescription Drug User Fee Act (PDUFA) action dates of December 8, 2023, for SCD and March 30, 2024, for TDT. Exa-cel's BLA for SCD was granted Priority Review by the FDA. The FDA has indicated that they plan to hold an advisory committee meeting for exa-cel. In the U.S., exa-cel has been granted Fast Track, Regenerative Medicine Advanced Therapy (RMAT), Orphan Drug and Rare Pediatric Disease designations. As with the U.S. FDA, reviews of the regulatory filings for exa-cel with the EMA in the EU and the MHRA in the U.K. are well underway. Exa-cel has been granted Priority Medicines (PRIME) and Orphan Drug designation in the EU. In the U.K., exa-cel has been granted an Innovation Passport under the Innovative Licensing and Access Pathway from the MHRA. At the 2023 Annual European Hematology Association (EHA) Congress in June, Vertex presented positive interim results from the pivotal trials of exa-cel in SCD and TDT as of a September 2022 data cut. Both trials met the primary and key secondary endpoints at pre-specified interim analyses, and the data continue to demonstrate transformative, consistent and durable benefit. The data presented at EHA were the basis of the EMA and MHRA regulatory filings for exa-cel. Vertex expects to present updated clinical data that served as the basis of the FDA filing at a future medical congress. Dosing in the Phase 1/2/3 CLIMB-111 and CLIMB-121 studies is ongoing, and Vertex continues to enroll and follow patients in the CLIMB-131 long-term follow-up study. Vanzacaftor/tezacaftor/deutivacaftor, the next-in-class triple combination, in cystic fibrosis. In the fourth quarter of 2022, Vertex completed enrollment in the pivotal SKYLINE 102 and SKYLINE 103 trials, which evaluate the efficacy and safety of vanzacaftor/tezacaftor/deutivacaftor relative to TRIKAFTA in patients with CF 12 years of age and older. More recently, Vertex also completed enrollment in the RIDGELINE study of vanzacaftor/tezacaftor/deutivacaftor in children with CF 6 to 11 years of age. Vertex expects to complete both the SKYLINE and RIDGELINE studies by the end of 2023 and share the results of these studies in early 2024. VX-548 in acute pain: Vertex has discovered multiple selective small molecule inhibitors of NaV1.8 with the objective of creating a new class of pain medicines that have the potential to provide effective pain relief, without the limitations of opioids and other currently available medicines. Vertex continues to enroll the Phase 3 pivotal program, including two randomized controlled trials in abdominoplasty and bunionectomy and a single arm safety and effectiveness trial, for its lead compound, VX-548, for the treatment of moderate to severe acute pain. Vertex expects to complete the pivotal program in late 2023 and share results from these studies in late 2023 or early 2024. In the U.S., VX-548 has been granted Breakthrough Therapy and Fast Track designations for moderate to severe acute pain. R&D Pipeline Vertex is delivering on a diversified pipeline of potentially transformative small molecule, mRNA, cell and genetic therapies aimed at serious diseases. Recent and anticipated progress for programs in clinical development is summarized below. Cystic Fibrosis Vertex continues to pursue next-in-class, small molecule CFTR modulator therapies, as well as an mRNA therapy for the approximately 5,000 patients who cannot benefit from CFTR modulators alone. Vertex is developing VX-522, a CFTR mRNA therapeutic, in collaboration with Moderna. The goal of this therapy is to treat the underlying cause of CF by programming cells in the lungs to produce functional CFTR protein, and it is aimed at the treatment of the approximately 5,000 people with CF who do not produce any CFTR protein. Vertex is enrolling patients in a single ascending dose (SAD) clinical trial for VX-522, and the Company expects to complete the SAD and initiate a multiple ascending dose (MAD) study in 2023. In the U.S., the FDA has granted Fast Track designation to VX-522. Consistent with its overall strategy, Vertex takes a portfolio approach to all of its programs and is advancing additional CFTR modulators with the goal of bringing more patients to carrier levels of sweat chloride. Beta Thalassemia and Sickle Cell Disease Two global Phase 3 studies of exa-cel continue to enroll and dose patients 5 to 11 years of age with TDT or SCD. Additionally, Vertex continues to work on preclinical assets for gentler conditioning for exa-cel, which could broaden the eligible patient population from 32,000 patients to more than 150,000. Acute and Neuropathic Pain The Phase 2 dose-ranging study of VX-548 in patients with diabetic peripheral neuropathy, a common form of peripheral neuropathic pain, has been fully enrolled. Dosing in the Phase 2, 12-week VX-548 study continues, and Vertex expects to complete this study in late 2023 and share results in late 2023 or early 2024. Consistent with its overall strategy, Vertex takes a portfolio approach to all of its programs and is advancing additional NaV1.8 inhibitors as well as NaV1.7 inhibitors through research and earlier stages of development for pain. APOL1-Mediated Kidney Disease (AMKD) Vertex has discovered multiple oral, small molecule inhibitors of APOL1 function, pioneering a new class of medicines that target an underlying genetic driver of kidney disease. Vertex continues to enroll and dose patients in the pivotal program for inaxaplin, a single Phase 2/3 clinical trial in patients with AMKD, and expects to complete the Phase 2B dose-ranging portion of the study in 2023. Inaxaplin was granted Breakthrough Therapy designation by the FDA for FSGS, as well as Orphan Drug and PRIME designations by the EMA for AMKD. Type 1 Diabetes (T1D) Vertex is evaluating cell therapies using stem-cell derived, fully differentiated, insulin-producing islet cells to replace the endogenous insulin-producing islet cells that are destroyed in people with T1D, with the goal of developing a potential functional cure for this disease. Vertex has three programs that use these fully differentiated cells. VX-880, fully differentiated cells with standard immunosuppression: Vertex established proof-of-concept for VX-880 in 2022. In June 2023, Vertex presented positive, updated clinical data from the ongoing VX-880 Phase 1/2 study at the American Diabetes Association Scientific Sessions (ADA). The Phase 1/2 study is designed as a sequential, multi-part clinical trial to evaluate the safety and efficacy of VX-880. In Part A, the first two patients received half the target dose of VX-880 cells. In Part B, patients received the full target dose with staggered dosing. Based on the results from Parts A and B, Vertex has initiated Part C of the study, with concurrent dosing at the full target dose, with trial sites currently active in the U.S., Canada, Norway, Switzerland, the Netherlands and France. In the data presented at ADA, all patients from Parts A and B of the study treated with VX-880 engrafted islet cells, produced endogenous insulin (C-peptide) and had improved glycemic control while reducing or eliminating insulin use. The two patients with at least one year of follow-up met the criteria for the primary endpoint of elimination of severe hypoglycemic events (SHEs) and HbA1C <7.0 and also achieved insulin independence. VX-264, fully differentiated islet cells encapsulated in immunoprotective device: VX-264 uses the same stem cell-derived, fully differentiated islets used in the VX-880 program, which are encapsulated in a novel device designed to shield the cells from the body’s immune system and obviate the need for immunosuppressive therapy. Vertex is enrolling and dosing patients with VX-264 in a Phase 1/2 clinical trial that is a sequential, multi-part study to evaluate the safety, tolerability and efficacy of VX-264. Part A of the study will dose patients with a partial dose of cells and a stagger between patients, and Part B will dose patients with a full target dose and a stagger between patients before moving to concurrent dosing in Part C. The study is enrolling patients in the U.S., Canada and the Netherlands, with additional global sites to be activated in the coming months. The first patient in Part A has been dosed. Edited fully differentiated cells: Vertex’s hypoimmune cell program involves using CRISPR/Cas9 to gene edit the same stem cell-derived, fully differentiated islets used in the VX-880 and VX-264 programs, in order to cloak the cells from the immune system. This is yet another possible path to eliminate the need for immunosuppressive therapy. This program is progressing through the research stage. To further expand Vertex’s capabilities in cell therapy manufacturing, in June 2023, Vertex and Lonza announced a strategic agreement to support the manufacture of Vertex’s portfolio of investigational stem cell-derived, fully differentiated insulin-producing islet cell therapy. This agreement will help accelerate the development and commercialization of Vertex’s potentially transformative cell therapy products for T1D. Alpha-1 Antitrypsin Deficiency Vertex is working to address the underlying genetic cause of alpha-1 antitrypsin (AAT) deficiency by developing novel small molecule correctors of Z-AAT protein folding, with a goal of increasing the secretion of functional AAT into the blood and addressing both the lung and the liver aspects of AAT deficiency. Vertex is enrolling and dosing patients in a 48-week Phase 2 study of VX-864, a first-generation AAT corrector, to assess the impact of longer-term treatment on polymer clearance from the liver, as well as the resultant levels of functional AAT (fAAT) in the plasma. Vertex expects to complete enrollment in this study in 2023. Additionally, Vertex continues to enroll and dose healthy volunteers with VX-634, a follow-on small molecule AAT corrector. VX-634 is the first in a series of next-wave investigational molecules with significantly improved potency and drug-like properties compared to previous Vertex AAT correctors. Vertex expects to complete enrollment and dosing in this study in 2023. Muscular Dystrophies Vertex is also advancing preclinical assets in muscular dystrophies, including Duchenne muscular dystrophy (DMD) and myotonic dystrophy type 1 (DM1). Investments in External Innovation As part of the collaboration with CRISPR Therapeutics on hypoimmune cells for T1D, Vertex achieved a research milestone in the second quarter of 2023, resulting in a $70 million milestone payment payable to CRISPR.

- Results from clinically predictive CFHBE model suggest NBD1 stabilizers enable multiple potential paths to full restoration of CFTR function - BOSTON, June 8, 2023 /PRNewswire/ -- Sionna Therapeutics, a life sciences company dedicated to developing highly effective and differentiated treatments for cystic fibrosis (CF), today announced the presentation of preclinical data demonstrating the activity of the company's portfolio of compounds targeting the first nucleotide-binding domain (NBD1) of the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The results are being presented at the European Cystic Fibrosis Society (ECFS) 46th European Cystic Fibrosis Conference held June 7-10 in Vienna, Austria. "Without NBD1 stabilization, the ability to correct the CFTR protein is limited, but this has long been considered an undruggable target in CF," said Mike Cloonan, President and Chief Executive Officer of Sionna. "Our goal is to deliver new therapies of unprecedented efficacy to patients with a development program that is anchored by NBD1 stabilizers." CF is caused by mutations in the CFTR gene, which codes for an epithelial ion channel that is essential for producing healthy, freely flowing mucus in the airways, digestive system, and other organs. The most common mutation in CFTR, ΔF508, causes NBD1 to unfold at body temperature and severely impairs CFTR function. Sionna is developing a portfolio of novel small molecules targeting NBD1 and complementary mechanisms. In the poster, titled, "Novel CFTR Modulator Combinations Directly Address the ΔF508-CFTR NBD1 Stability Defect and Enable Full CFTR Correction," Greg Hurlbut, Ph.D., Co-Founder and Senior Vice President, Discovery Research of Sionna, presents data from functional and biochemical assays that demonstrate the activity of Sionna's NBD1 stabilizers alone and in combination with the company's intracellular loop 4 (ICL4)- and transmembrane domain 1 (TMD1)-directed correctors, and standard-of-care CFTR modulators. Sionna's NBD1 stabilizers demonstrated the ability to restore ΔF508-CFTR maturation, trafficking, and function to wild-type levels when combined with mechanistically complementary agents. Data from the clinically predictive human bronchial epithelial cell (CFHBE) model suggest that NBD1 stabilizers enable multiple potential paths to full restoration of CFTR function for most people living with CF. "For the past 14 years, our team has focused on the discovery of NBD1 stabilizers and complementary modulators that have the potential to restore wild-type function to ΔF508-CFTR," said Dr. Hurlbut. "This research has led to a novel strategy for discovering small molecules that directly address the molecular pathology of the most common CF-causing mutation." Sionna is currently conducting a Phase 1 clinical trial evaluating its lead NBD1 modulator, SION-638, and has nominated two additional NBD1 modulators, SION-719 and SION-451, entering Investigational New Drug application (IND) enabling studies in the second half of 2023. The company is also advancing the development of compounds targeting complementary mechanisms including SION-109, which targets NBD1's interface with the ICL4 region, and SION-676, which targets the TMD1 of CFTR. About Sionna Therapeutics Sionna Therapeutics is a life sciences company dedicated to developing highly effective and differentiated treatments for cystic fibrosis (CF) by normalizing the function of CFTR, the key protein associated with disease progression in CF. Building on over a decade of extensive research on the genetic mutations associated with CF and founded in 2019, Sionna is advancing a pipeline of small molecules engineered to correct the protein defects caused by ΔF508, the most common mutation that affects the CFTR protein. The company has a first-in-class portfolio of programs directly targeting correction of NBD1, the key and unique mechanism to enable full restoration of ΔF508-CFTR function, and complementary programs targeting ICL4 and TMD1. Sionna's pipeline has the potential to deliver best-in-class efficacy and reach previously unachievable levels of long-term benefit for people with CF. For information about Sionna visit .
