Vertex Reports First Quarter 2024 Financial Results

Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today reported consolidated financial results for the first quarter ended March 31, 2024, and reiterated full year 2024 financial guidance.

"Vertex delivered a strong start to 2024 with 13 percent product revenue growth and outstanding execution across the business. This quarter, we continued to expand our leadership in CF including completion of the regulatory submissions for the vanzacaftor triple, advanced the global launch of CASGEVY^tm, and initiated the rolling submission for suzetrigine in moderate-to-severe acute pain, while progressing our broad and deep pipeline of potentially transformative medicines," said Reshma Kewalramani, M.D., Chief Executive Officer and President of Vertex. "We also recently announced the acquisition of Alpine Immune Sciences, a compelling strategic fit. We look forward to welcoming the Alpine team and together accelerating the development of povetacicept, a potential best-in-class treatment for IgAN, and fully exploring povetacicept's pipeline-in-a-product potential."

First Quarter 2024 Results

Product revenue increased 13% to $2.69 billion compared to the first quarter of 2023, primarily driven in ex-U.S. markets by the continued strong uptake of TRIKAFTA^®/KAFTRIO^®, including label extensions in younger age groups, and in the U.S. by the continued performance of TRIKAFTA, including the uptake in children with CF 2 to 5 years of age. Net product revenue in the first quarter of 2024 increased 8% to $1.52 billion in the U.S. and increased 21% to $1.17 billion outside the U.S., compared to the first quarter of 2023.

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 $1.3 billion and $1.2 billion, respectively, in the first quarter of 2023. The decreases were due to lower Acquired IPR&D expenses partially offset by 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.

GAAP effective tax rate was 14.0% compared to 21.5% for the first quarter of 2023, primarily due to a discrete adjustment to Vertex's income tax reserves as well as tax benefits related to stock-based compensation.

Non-GAAP effective tax rate was 17.4% compared to 21.3% for the first quarter of 2023, primarily due to a discrete adjustment to Vertex's income tax reserves. Please refer to Note 1 for further details on Vertex's GAAP to Non-GAAP tax adjustments.

GAAP and Non-GAAP net income increased by 57% and 56%, respectively, compared to the first quarter of 2023, primarily due to higher product revenues and lower Acquired IPR&D expenses.

Cash, cash equivalents and total marketable securities as of March 31, 2024 were $14.6 billion, compared to $13.7 billion as of December 31, 2023. The increase was primarily due to cash from operations driven by strong revenue growth, partially offset by business development payments, and repurchases of Vertex's common stock.

Full Year 2024 Financial Guidance

Vertex today reiterated its full year 2024 financial guidance, including product revenue guidance of $10.55 to $10.75 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. Vertex's combined Non-GAAP R&D, Acquired IPR&D and SG&A expense guidance of $4.3 billion to $4.4 billion includes expectations for continued investment in multiple mid- and late-stage clinical development programs, commercial and manufacturing capabilities, and approximately $125 million of upfront and milestone payments. The recently announced acquisition of Alpine Immune Sciences is expected to close in the second quarter. Vertex does not anticipate adjusting its guidance for Alpine's operating expenses, other than the potential impact of purchase accounting.

Vertex's 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 our medicines will continue to grow through new approvals and reimbursement for the treatment of younger patients. Recent and anticipated progress includes:

• The European Commission has granted approval for 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 the first quarter, Vertex shared positive data from the pivotal studies for the next-generation triple combination of vanzacaftor/tezacaftor/deutivacaftor (the "vanzacaftor triple"), showing that the two randomized studies in patients 12 years and older met the primary endpoint and all key secondary endpoints, and the results in the single-arm study in children ages 6 to 11 were even more pronounced.
• Vertex has submitted regulatory marketing applications for the once-daily vanzacaftor triple in people with CF 6 years and older to the U.S. Food and Drug Administration (FDA), using a priority review voucher, and to the European Medicines Agency (EMA). Vertex intends to complete regulatory submissions to the MHRA in Great Britain, Health Canada, SwissMedic, the Australian Therapeutic Goods Administration (TGA) and the New Zealand Ministry of Health for people with CF 6 years of age and older later this year.

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 European Union (EU), the Kingdom of Saudi Arabia (KSA), and the Kingdom of Bahrain (Bahrain) for the treatment of both SCD and TDT. Vertex has completed regulatory submissions for CASGEVY for SCD and TDT in Switzerland and Canada; the submission in Canada was granted priority review.
• As of mid-April, Vertex has activated more than 25 authorized treatment centers (ATCs) globally and multiple patients across all regions have initiated cell collection.
• Vertex has signed multiple agreements with both commercial and government health insurance providers in the U.S. to provide access to CASGEVY.
• Vertex has also secured reimbursed access for people with SCD or TDT in KSA and Bahrain, as well as for people with TDT in France through an early access program.

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 across a variety of pain states, without the limitations of opioids and other currently available medicines.

• In the first quarter, Vertex shared positive results from the three Phase 3 trials of suzetrigine in moderate-to-severe acute pain.
• The FDA has granted a rolling New Drug Application (NDA) submission to suzetrigine in moderate-to-severe acute pain, and Vertex has started the rolling submission process. The submission is on track to be completed in the second quarter of 2024. Suzetrigine has also been granted FDA Fast Track and Breakthrough Therapy designations in 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 patients 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 plans to initiate a new cohort in the Phase 3 study, RIDGELINE, in the second half of 2024 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.
• Nebulized mRNA therapy:
  • Vertex continues to enroll and dose patients in the multiple ascending dose (MAD) portion of the Phase 1/2 study of VX-522 in people with CF.
  • Vertex expects to share data from this study in late 2024 or early 2025.

Sickle Cell Disease and Transfusion-Dependent Beta Thalassemia

• Vertex has completed enrollment in two global Phase 3 studies of CASGEVY in people 5 to 11 years of age with SCD or TDT.
• 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.

Acute Pain

• Vertex plans to initiate a Phase 2 study with an oral formulation of VX-993, a next-generation selective NaV1.8 inhibitor, for the treatment of moderate to severe acute pain in 2024.
• The FDA cleared the investigational new drug (IND) application for an intravenous formulation of VX-993 for the treatment of moderate to severe acute pain, and Vertex has initiated a Phase 1 trial.
• Consistent with its commitment to serial innovation and leadership in pain, Vertex also continues to develop NaV1.7 inhibitors, for stand-alone use or in combination with NaV1.8 inhibitors, for both acute and peripheral neuropathic pain.

Peripheral Neuropathic Pain (PNP)

• Following a successful end-of-Phase 2 meeting with the FDA, 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, in the second half of 2024. The FDA recently granted suzetrigine Breakthrough Therapy designation in this indication.
• Vertex continues to enroll and dose patients in its Phase 2 study of suzetrigine in painful lumbosacral radiculopathy (LSR), representing ~40% of the PNP category. Vertex is on track to complete enrollment in the Phase 2 study by the end of 2024.
• Vertex anticipates initiating a Phase 2 study with an oral formulation of VX-993 for the treatment of PNP in 2024.

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.

• Based on the totality of the unblinded data reviewed by the Independent Data Safety Monitoring Committee (IDMC), Vertex advanced into the Phase 3 portion of the global Phase 2/3 pivotal clinical trial in patients with AMKD, in which a 45 mg once-daily oral dose of inaxaplin will be compared to placebo, on top of standard of care.
• In addition, based on the IDMC review, the trial has been expanded to include adolescents 10 to 17 years of age with AMKD.
• The study is designed to have a pre-planned interim analysis at Week 48 evaluating eGFR slope, 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.

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:
  • Based on the totality of evidence reviewed by the IDMC, the Phase 1/2 study in people with T1D and impaired awareness of hypoglycemia and recurrent hypoglycemic events has resumed dosing.
  • Vertex has completed enrollment in Parts A, B, and C of the global 17-patient study and expects to complete dosing soon.
  • Vertex plans to present updated data from the ongoing Phase 1/2 study at the American Diabetes Association 84th Scientific Sessions Conference in June 2024.
• 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 designed to eliminate the need for immunosuppressants, is a multi-part, Phase 1/2 study.
  • Vertex has completed Part A of the study and initiated Part B.
• 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 islet cells used in the VX-880 and VX-264 programs to cloak the cells from the immune system. This program is progressing through the research stage.

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, was in-licensed from Entrada Therapeutics in February 2023 and is an oligonucleotide connected to a cyclic peptide to promote effective delivery into cells, which holds the potential to address the underlying cause of DM1.

• The IND in the U.S. for VX-670 has cleared, as have the clinical trial applications (CTAs) in Canada, the U.K. and the EU, and the clinical trial notification (CTN) in Australia.
• Enrollment and dosing are underway.

Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Vertex is developing small molecule correctors that restore function to PC1 missense variants, with the goal to address the underlying cause of ADPKD, the most common genetic kidney disease, affecting approximately 250,000 people in the U.S. and Europe.

• Vertex has initiated 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 PKD1 variants, estimated at ~25,000 (or ~10 percent) of the overall ~250,000 ADPKD patient population.

Investments in External Innovation

• Vertex and Alpine Immune Sciences entered into a definitive agreement under which Vertex will acquire Alpine for approximately $4.9 billion in cash. Vertex has commenced a tender offer to purchase all of the outstanding shares of common stock of Alpine for $65 per share in cash. The transaction is anticipated to close in the second quarter of 2024. Alpine's lead molecule, povetacicept, is a highly potent and effective dual antagonist of BAFF (B cell activating factor) and APRIL (a proliferation-inducing ligand). Through Phase 2 development, povetacicept has shown potential best-in-class efficacy in IgA nephropathy (IgAN), a serious, progressive, autoimmune disease of the kidney that can lead to end-stage-renal disease. There are currently no approved therapies that target the underlying cause of IgAN, which is the most common cause of primary (idiopathic) glomerulonephritis worldwide, affecting approximately 130,000 people in the U.S. alone. Povetacicept is on track to enter Phase 3 clinical development in IgAN in the second half of 2024. Phase 1b/2 studies in autoimmune renal diseases and cytopenias are ongoing with data expected later this year.
• Vertex achieved a clinical milestone for VX-670 in DM1 in the first quarter of 2024, resulting in a $75 million milestone payable to Entrada.
