Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today reported consolidated financial results for the second quarter ended June 30, 2024, and raised its full year product revenue guidance to $10.65 to $10.85 billion.

“Vertex delivered another strong quarter of revenue growth coupled with outstanding execution across the business, and we are increasing our full year product revenue guidance,” said Reshma Kewalramani, M.D., Chief Executive Officer, and President of Vertex. “Our focus for the second half of the year remains on commercial execution in CF and the global launch of CASGEVY, readying for the upcoming potential launches of the vanzacaftor triple in CF and suzetrigine in acute pain, while rapidly advancing a robust pipeline that is poised to deliver value for patients and shareholders for the long term.”

Second Quarter 2024 Results

Product revenue increased 6% to $2.65 billion compared to the second quarter of 2023, primarily driven by the continued strong performance of TRIKAFTA^®/KAFTRIO^®, including in younger age groups. Net product revenue in the second quarter of 2024 increased 7% to $1.61 billion in the U.S. and increased 5% to $1.03 billion outside the U.S., compared to the second quarter of 2023.

Combined GAAP and Non-GAAP R&D and SG&A expenses were $1.3 billion and $978 million, respectively, compared to $1.0 billion and $928 million, respectively, in the second quarter of 2023. The increases were due to increased investments to support launches of Vertex's therapies globally and continued investment in support of multiple programs that have advanced in mid- and late-stage clinical development.

Acquired IPR&D expenses were $4.4 billion compared to $111 million in the second quarter of 2023 due to $4.4 billion of Acquired IPR&D (AIPR&D) expenses associated with Vertex’s acquisition of Alpine Immune Sciences.

GAAP and Non-GAAP effective tax rates were (6.0)% and (10.0)%, respectively, compared to 21.2% and 21.0%, respectively, for the second quarter of 2023, primarily due to the impact of non-deductible AIPR&D expenses, which drove Vertex’s pre-tax loss in the second quarter of 2024. Please refer to Note 1 for further details on Vertex’s GAAP to Non-GAAP tax adjustments.

GAAP and Non-GAAP net losses were $3.6 billion and $3.3 billion, respectively, compared to net income of $916 million and $1.0 billion for the second quarter of 2023, respectively, given the impact of the Alpine AIPR&D expense in the second quarter of 2024.

Cash, cash equivalents and total marketable securities as of June 30, 2024 were $10.2 billion, compared to $13.7 billion as of December 31, 2023. The reduction in Vertex’s cash, cash equivalent and marketable securities balance compared to December 31, 2023, was due to the cash consideration paid to acquire Alpine in the second quarter of 2024, partially offset by positive cash flows provided by other operating activities.

Full Year 2024 Financial Guidance

Vertex today raised its full year product revenue guidance from $10.55-$10.75 billion to $10.65-$10.85 billion. Vertex’s product revenue guidance includes expectations for continued growth in CF as well as for the launch of CASGEVY^® in approved indications and geographies. Given the impact of the Alpine acquisition, for 2024, Vertex is now providing guidance for both combined GAAP and Non-GAAP R&D and SG&A expenses and for AIPR&D expenses. Vertex continues to expect combined Non-GAAP R&D and SG&A expenses to be in a range of $4.2 billion to $4.3 billion for the full year. This includes Vertex’s expectations for continued investment in multiple mid- and late-stage clinical development programs and commercial and manufacturing capabilities and the inclusion of Alpine operating expenses for the remainder of 2024. Vertex now expects 2024 AIPR&D expenses of approximately $4.6 billion for the full year, including the Alpine acquisition-related charge in the second quarter of 2024.

Vertex’s updated financial guidance is summarized below:

Key Business Highlights

Marketed Products and Potential Near-Term Launch Opportunities

Cystic Fibrosis (CF) Portfolio

Vertex anticipates the number of CF patients taking its medicines will continue to grow through new approvals and reimbursement for the treatment of younger patients. Recent and anticipated progress includes:

• The U.S. Food and Drug Administration (FDA) accepted the New Drug Application (NDA) for the once-daily vanzacaftor triple in people with CF 6 years and older and assigned Priority Review with a Prescription Drug User Fee Act (PDUFA) target action date of January 2, 2025. Vertex also received validation of its vanzacaftor triple Marketing Authorization Application (MAA) submissions from the European Medicines Agency (EMA) in the European Union (EU), and the Medicines and Healthcare products Regulatory Agency (MHRA) in the U.K. Vertex has also completed regulatory submissions for the vanzacaftor triple in Canada, Australia, New Zealand and Switzerland.
• Vertex announced an extended long-term reimbursement agreement with NHS England providing access to KAFTRIO, SYMKEVI^® and ORKAMBI^® and continued access to KALYDECO^® for all existing and future eligible CF patients in England. Vertex has entered into similar agreements in Wales, Northern Ireland and Scotland. The agreements, which also include access to any future license extensions of these medicines, are a result of the National Institute for Health and Care Excellence’s (NICE) and the Scottish Medicines Consortium’s (SMC) positive recommendations for Vertex’s CFTR modulators.
• In May, the European Commission granted approval to KALYDECO for the treatment of infants with CF ages 1 month to less than 4 months with specific mutations in the CFTR gene. KALYDECO now represents the first and only medicine approved in Europe to treat the underlying cause of CF for this age group.
• In July, Health Canada granted approval to TRIKAFTA for the treatment of people with CF with 152 rare responsive mutations in the CFTR gene. This represents the first approval outside of the United States where the mutations were approved based on in vitro data.
• Vertex has submitted regulatory applications to the FDA and EMA for TRIKAFTA/KAFTRIO for the treatment of people with CF and rare responsive mutations.

CASGEVY for the treatment of sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT)

CASGEVY is a non-viral, ex vivo CRISPR/Cas9 gene-edited cell therapy for eligible patients with SCD or TDT that has been shown to reduce or eliminate vaso-occlusive crises (VOCs) for patients with SCD and transfusion requirements for patients with TDT. CASGEVY is approved in the U.S., Great Britain, the EU, the Kingdom of Saudi Arabia (KSA), and the Kingdom of Bahrain (Bahrain) for the treatment of both SCD and TDT, and launches are ongoing.

• Vertex has completed regulatory submissions for CASGEVY for SCD and TDT in Switzerland and in Canada, where it received Priority Review.
• As of mid-July, Vertex has activated more than 35 authorized treatment centers (ATCs) globally and increasing numbers of patients across all regions have initiated cell collection.
• The French National Authority for Health (HAS) approved Vertex’s request for the implementation of an early access program (EAP) for the use of CASGEVY in indicated patients with SCD. HAS previously approved the implementation of an EAP for CASGEVY in indicated patients with TDT in the first quarter of 2024.
• Vertex continues to generate data from CLIMB-111, CLIMB-121 and the long-term follow-up study of CASGEVY and presented positive long-term data at the 2024 Annual European Hematology Association (EHA) Congress in June. These long-term data from more than 100 patients dosed with CASGEVY, with the longest follow-up of more than five years, confirm the transformative, consistent, and durable clinical benefits of CASGEVY over time.

Suzetrigine (VX-548) for the treatment of moderate to severe acute pain

Vertex has discovered multiple selective small molecule inhibitors of NaV1.8 with the goal of creating a new class of pain medicines that has the potential to provide effective pain relief without the limitations of opioids and other currently available medicines.

• The FDA accepted the NDA submission for suzetrigine for the treatment of moderate-to-severe acute pain and granted Priority Review with a PDUFA target action date of January 30, 2025. Suzetrigine has already been granted FDA Fast Track and Breakthrough Therapy designations for the treatment of moderate-to-severe acute pain.

Select Clinical-Stage R&D Pipeline

Cystic Fibrosis

Vertex continues to pursue next-in-class, small molecule, oral CFTR modulators for the ~90% of people with CF who may benefit from such an approach, as well as a nebulized mRNA therapy for the more than 5,000 people with CF who do not make CFTR protein and cannot benefit from CFTR modulators.

• Vanzacaftor/tezacaftor/deutivacaftor, the next-in-class triple oral small molecule combination, in cystic fibrosis
  • Vertex initiated a study in children with cystic fibrosis ages 2 to 5 years who have at least one F508del mutation or a mutation responsive to triple combination CFTR modulators.
• Consistent with its commitment to serial innovation and bringing as many patients as possible to normal levels of CFTR function, Vertex continues to advance new oral small molecule combination therapies through preclinical and clinical development. The most advanced next-wave CFTR modulators have completed, or are in the process of completing, Phase 1 clinical trials.
• VX-522, nebulized mRNA therapy
  • Vertex completed the single ascending dose (SAD) portion of the Phase 1/2 study of VX-522 in people with CF late last year, and the multiple ascending dose (MAD) portion of the study is ongoing. Vertex expects to complete the trial and share data from this study in the first half of 2025.

Sickle Cell Disease and Transfusion-Dependent Beta Thalassemia

• Vertex has completed enrollment in two global Phase 3 studies of CASGEVY in children 5 to 11 years of age with SCD or TDT and the trials are ongoing.
• Vertex continues to work on preclinical assets for gentler conditioning for CASGEVY, which could broaden the eligible patient population to more than 150,000 people in the U.S. and Europe alone.

Acute Pain

• Vertex is enrolling and dosing a Phase 1 trial for an intravenous formulation of VX-993, a next-generation selective NaV1.8 pain signal inhibitor.
• Vertex is on track to initiate a Phase 2 study this quarter with an oral formulation of VX-993 for the treatment of moderate to severe acute pain following bunionectomy surgery.

Peripheral Neuropathic Pain (PNP)

• Vertex is on track to initiate the Phase 3 pivotal program of suzetrigine in patients with painful diabetic peripheral neuropathy (DPN), a type of PNP, this quarter. The pivotal program is designed with two identical randomized controlled trials of approximately 1,100 patients each, studying suzetrigine at a once-daily 70mg dose. The primary endpoint is the change from baseline in the weekly average of daily pain intensity on the numeric pain rating scale (NPRS) at week 12 compared to placebo. The study also includes an active comparator arm of pregabalin, and a key secondary endpoint is non-inferiority on change from baseline to week 12 in NPRS score versus pregabalin. The FDA has granted suzetrigine Breakthrough Therapy Designation in DPN.
• Vertex has completed enrollment in its Phase 2 study of suzetrigine in painful lumbosacral radiculopathy (LSR), a condition representing more than 40% of patients suffering from PNP. Vertex expects to share results from this study in late 2024.
• Vertex is on track to initiate a Phase 2 study this quarter with an oral formulation of VX-993 for the treatment of DPN.

Consistent with its commitment to serial innovation and leadership in pain, Vertex also continues to develop additional NaV1.8 inhibitors and NaV1.7 inhibitors, for stand-alone use or in combination, for the treatment of acute and peripheral neuropathic pain.

APOL1-Mediated Kidney Disease (AMKD)

Vertex has discovered and advanced multiple oral, small molecule inhibitors of APOL1 function, pioneering a new class of medicines that targets an underlying genetic driver of this kidney disease.

• Vertex continues to enroll and dose patients with AMKD in the Phase 3 portion of the global Phase 2/3 pivotal clinical trial, in which a 45 mg once-daily dose of inaxaplin is compared to placebo, on top of standard of care.
• The study is designed to have a pre-planned interim analysis at Week 48 evaluating estimated glomerular filtration rate (eGFR) slope, a measure of kidney function, supported by a percent change from baseline in proteinuria, in the inaxaplin arm versus placebo. If positive, the interim analysis may serve as the basis for Vertex to seek accelerated approval in the U.S.

IgA Nephropathy (IgAN) and Other B Cell-Mediated Diseases

Vertex is developing povetacicept, a dual inhibitor of the BAFF and APRIL pathways, as a potentially best-in-class approach to treat IgA nephropathy, a serious progressive, autoimmune kidney disease that can lead to end-stage renal disease. IgAN is the most common form of glomerulonephritis worldwide, affecting approximately 130,000 people in the U.S. alone, and there are currently no approved therapies that target its underlying cause. Vertex is also studying povetacicept in other serious B cell-mediated diseases, including autoimmune kidney diseases and autoimmune cytopenias.

• Following successful end-of-phase 2 regulatory interactions, Vertex is on track to initiate the Phase 3 clinical trial of povetacicept in IgA nephropathy (the RAINIER study) this quarter.
• RAINIER is a global pivotal trial of povetacicept 80 mg vs. placebo on top of standard of care in approximately 480 people with IgAN. The study is designed to have a pre-planned interim analysis evaluating urine protein creatinine ratio (UPCR) for the povetacicept arm versus placebo after a certain number of patients reach 36 weeks of treatment. If positive, the interim analysis may serve as the basis for Vertex to seek accelerated approval in the U.S. Final analysis will occur at two years of treatment, with a primary endpoint of total eGFR slope through Week 104.
• The RUBY3 (autoimmune kidney diseases) and RUBY4 (autoimmune cytopenias) Phase 2 basket trials are ongoing with data readouts from certain cohorts expected later this year and into 2025.

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 one-time functional cure for this disease.

• VX-880, fully differentiated islet cells with standard immunosuppression:
  • Vertex announced positive results from the ongoing Phase 1/2 study at the American Diabetes Association 84^th Scientific Sessions Conference in June 2024.
    • All 12 patients who received the full dose of VX-880 as a single infusion demonstrated islet cell engraftment and glucose-responsive insulin production.
    • All of these patients achieved ADA-recommended HbA1c levels <7.0% and >70% time-in-range, and 11 of 12 patients reduced or eliminated use of exogenous insulin.
    • All three of the patients with at least 12 months of follow-up, and therefore evaluable for the primary endpoint, met the primary endpoint of elimination of severe hypoglycemic events (SHEs) with HbA1c <7.0%, and the secondary endpoint of insulin independence.
  • Based on these positive results, Vertex has expanded the Phase 1/2 study to include 37 total patients. Vertex has completed enrollment and dosing in the original Phase 1/2 17-patient study.
• VX-264, fully differentiated islet cells encapsulated in an immunoprotective device:
  • The clinical trial for VX-264, which encapsulates the same VX-880 islet cells in a novel device so that treatment with immunosuppressants is not required, is a global, multi-part, Phase 1/2 study.
  • Vertex has completed Part A of the study. As with the VX-880 study, patients in Part A receive a low dose with a stagger period between dosing. Part B of the Phase 1/2 is underway and enrolling and dosing. In Part B, patients receive the full target dose with a stagger period between patients, and in Part C, patients will receive the full target dose with no stagger.
• Hypoimmune, edited fully differentiated islet cells:
  • Vertex’s hypoimmune cell program involves using CRISPR/Cas9 to gene edit the same stem cell-derived, fully differentiated VX-880 islet cells to protect the cells from the immune system. This research-stage program continues to make progress.

Myotonic Dystrophy Type 1 (DM1)

Vertex is evaluating multiple approaches that target the underlying cause of DM1, the most prevalent muscular dystrophy in adults with ~110,000 people living with the disease in the U.S. and Europe, and no approved therapies. Vertex’s lead approach, VX-670, in-licensed from Entrada Therapeutics, is an oligonucleotide linked to a cyclic peptide to promote effective delivery into the cell and its nucleus, which holds the potential to address the underlying cause of DM1.

• Vertex continues to enroll and dose patients in the global Phase 1/2 clinical trial for VX-670 in people with DM1 and expects to complete the single ascending dose (SAD) portion of the study by the end of 2024.
• Following completion of the SAD portion of the trial, Vertex will move into the MAD portion, where both the safety and efficacy of VX-670 will be evaluated.

Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Vertex is developing small molecule correctors that restore function to the variant polycystin 1 (PC1) protein, with the goal of addressing the underlying cause of ADPKD, the most common genetic kidney disease, affecting approximately 250,000 people in the U.S. and Europe.

• Vertex is enrolling and dosing a Phase 1 clinical trial in healthy volunteers for VX-407, a first-in-class small molecule corrector that targets the underlying cause of ADPKD in patients with a subset of variants in the PKD1 gene, which encodes the PC1 protein, estimated to be ~25,000 (or ~10%) of the overall patient population.

Alpha-1 Antitrypsin Deficiency (AATD)

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.

• Based on Phase 1 biomarker analyses, Vertex has determined that VX-634 and VX-668, two investigational small molecule AAT correctors, would not deliver transformative efficacy for people with AATD. As such, Vertex has discontinued development of both molecules.
• Consistent with its portfolio approach to research and development, Vertex is using the learnings from VX-634, VX-668 and prior molecules to continue to optimize the small molecule corrector and other approaches in the preclinical research phase.

Investments in External Innovation

• In May, Vertex completed its previously announced acquisition of Alpine Immune Sciences for approximately $5.0 billion in cash, including Alpine’s lead asset povetacicept, resulting in an approximate $4.4 billion charge to AIPR&D expenses in the second quarter of 2024.

Non-GAAP Financial Measures

In this press release, Vertex's financial results and financial guidance are provided in accordance with accounting principles generally accepted in the United States (GAAP) and using certain non-GAAP financial measures. In particular, non-GAAP financial results and guidance exclude from Vertex's pre-tax income (loss) (i) stock-based compensation expense, (ii) intangible asset amortization expense, (iii) gains or losses related to the fair value of the company's strategic investments, (iv) increases or decreases in the fair value of contingent consideration, (v) acquisition-related costs, and (vi) other adjustments. The company's non-GAAP financial results also exclude from its provision for income taxes the estimated tax impact related to its non-GAAP adjustments to pre-tax income (loss) described above and certain discrete items. These results should not be viewed as a substitute for the company’s GAAP results and are provided as a complement to results provided in accordance with GAAP. Management believes these non-GAAP financial measures help indicate underlying trends in the company's business, are important in comparing current results with prior period results and provide additional information regarding the company's financial position that the company believes is helpful to an understanding of its ongoing business. Management also uses these non-GAAP financial measures to establish budgets and operational goals that are communicated internally and externally, to manage the company's business and to evaluate its performance. The company’s calculation of non-GAAP financial measures likely differs from the calculations used by other companies. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the attached financial information.

The company provides guidance regarding combined R&D and SG&A expenses and effective tax rate on a non-GAAP basis. The guidance regarding Acquired IPR&D expenses does not include estimates associated with any potential future business development transactions, including collaborations, asset acquisitions and/or licensing of third-party intellectual property rights. The company does not provide guidance regarding its GAAP effective tax rate because it is unable to forecast with reasonable certainty the impact of excess tax benefits related to stock-based compensation and the possibility of certain discrete items, which could be material.
