-Product revenues of $1.98 billion, a 29% increase compared to Q3 2020-

-Company raises full-year 2021 guidance for product revenues to $7.4 to $7.5 billion-

-Broad pipeline advancing with recent progress marked by unprecedented VX-880 clinical results in T1D; Phase 2 clinical results for VX-147 expected this quarter and for VX-548 in Q1 2022-

Vertex Pharmaceuticals Incorporated (NASDAQ:VRTX) today reported consolidated financial results for the third quarter ended September 30, 2021 and raised full-year 2021 product revenue guidance to $7.4 to $7.5 billion.

"Our financial performance in the third quarter was outstanding, marked by the exceptional continued growth of TRIKAFTA/KAFTRIO. Based on these results, we are again raising our 2021 product revenue guidance, and we see significant additional growth ahead as we continue to deliver this transformational medicine to more people with CF," said Reshma Kewalramani, M.D., Chief Executive Officer and President of Vertex. "During the last quarter, we also significantly expanded and advanced our pipeline. We announced unprecedented data from the first type 1 diabetes patient dosed with our stem cell-derived, allogeneic islet cells (VX-880). We completed enrollment in the Phase 2 proof-of-concept study of VX-147 in APOL1-mediated FSGS and will report results later this quarter. We also achieved target enrollment in both pivotal CTX001 studies to support our regulatory submissions next year. Finally, we made important advancements in our earlier stage pipeline and expect to submit INDs for both our CF mRNA program and type 1 diabetes cells and device program in 2022."

Key Business Highlights

Cystic Fibrosis (CF) Marketed Products

Vertex anticipates the number of CF patients treated with our medicines will continue to grow as we enter into additional reimbursement agreements, achieve new approvals for the treatment of younger patients, and expand treatment options for the approximately 10 percent of patients who do not benefit from cystic fibrosis transmembrane conductance regulator (CFTR) modulators, all of which will lead to continued growth of our CF business in the years ahead. Recent progress includes:

Vertex has signed a Letter of Intent (LOI) with the pan-Canadian Pharmaceutical Alliance (pCPA) regarding the public reimbursement of TRIKAFTA (elexacaftor/tezacaftor/ivacaftor and ivacaftor) for eligible patients with CF and has also reached multiple provincial agreements across Canada providing approximately 90% of Canadian patients 12 years of age and older and covered by government insurance with reimbursed access to TRIKAFTA.
Data are being presented at the North American CF Conference (NACFC) in November from the ongoing 192-week TRIKAFTA open-label extension study which show there has been no loss in mean lung function during long term follow-up at 96 weeks, a first for any CFTR modulator to date. Data from a retrospective study of KALYDECO (ivacaftor) will also be presented at the conference. The results showed that people with CF over approximately 6 years old had significantly lower rates of mortality, lung transplant and pulmonary exacerbations compared to those not on treatment.
Vertex's application for approval of TRIKAFTA in children 6 through 11 years of age has been accepted for priority review by Health Canada.

TRIKAFTA/KAFTRIO is now approved and reimbursed or accessible in more than 20 countries outside the U.S., including Italy, France and Canada.

R&D pipeline

Vertex is delivering on a diversified pipeline of potentially transformative small molecule, cell and genetic therapies aimed at serious diseases. Recent and anticipated progress for key pipeline programs is noted below:

Cystic Fibrosis

The Phase 3 studies evaluating the new once-daily investigational triple combination of VX-121/tezacaftor/VX-561 (deutivacaftor) are underway.
In collaboration with Moderna, Vertex is evaluating CF mRNA therapeutics designed to treat the underlying cause of CF by enabling cells in the lungs to produce functional CFTR protein for the treatment of the 10% of patients who do not produce any CFTR protein. IND-enabling studies are underway and Vertex expects to submit an IND for this program in 2022.

Beta Thalassemia and Sickle Cell Disease (SCD)

The CTX001 program employs a non-viral ex vivo CRISPR gene-editing therapy for the treatment of transfusion-dependent thalassemia (TDT) and severe SCD.
Data presented to date support the profile of CTX001 as a one-time functional cure for patients with TDT and severe SCD, showing consistent and durable benefit across all treated patients.
Target enrollment has been achieved in the ongoing clinical trials in TDT and SCD to support the planned regulatory submissions in late 2022.

Type 1 Diabetes (T1D)

Vertex is evaluating cell therapies designed to replace insulin-producing islet cells that are destroyed in people with T1D with the goal of delivering a potential functional cure.
VX-880 is a stem cell-derived, allogeneic, fully differentiated, insulin-secreting islet cell replacement therapy, using standard immunosuppression to protect the implanted cells. VX-880 is being evaluated in a Phase 1/2 clinical trial for the treatment of T1D.
In October, Vertex announced positive Day 90 data for the first T1D patient in the Phase 1/2 clinical trial of VX-880. The patient was treated with a single infusion of VX-880 at half the target dose in conjunction with standard immunosuppressive therapy. The patient demonstrated rapid and robust improvements in multiple measures, including significant increases in fasting and stimulated C-peptide, improvements in glycemic control as measured by HbA1c, and a 91% decrease in exogenous insulin requirements.
The VX-880 Phase 1/2 study is ongoing at multiple clinical sites in the U.S. and the Clinical Trial Application (CTA) has been approved in Canada.
Vertex is pursuing a second program in which these stem cell-derived, fully differentiated, insulin-secreting islet cells are encapsulated and implanted in an immunoprotective device. IND-enabling studies are underway and Vertex expects to submit an IND for the cells and device program in 2022.

APOL1-mediated Kidney Diseases (AMKD)

Vertex is evaluating the potential of oral, small molecule inhibitors of APOL1 function to treat people with AMKD.
Enrollment is complete in the Phase 2 proof-of-concept study evaluating VX-147 for the treatment of people with APOL1-mediated focal segmental glomerulosclerosis (FSGS) with reduction of proteinuria as the primary endpoint. Results from this study will be reported in the fourth quarter of 2021 and will inform the potential progression of VX-147 into pivotal studies in the broader population of people with APOL1-mediated non-diabetic proteinuric kidney diseases.
Preclinical data for VX-147 will be presented at the American Society of Nephrology Annual Meeting, November 4-7, 2021.

Pain (NaV1.8)

Vertex has discovered multiple selective small molecule inhibitors of NaV1.8 with the objective of creating a new class of medicines that have the potential to be highly effective for both acute and chronic pain, without the limitations of opioids and other existing pain medications.
Two Phase 2 dose ranging acute pain studies with VX-548 are underway, one following bunionectomy surgery and the other following abdominoplasty surgery. Data from the acute pain studies are expected in Q1 2022.

Alpha-1 Antitrypsin (AAT) Deficiency

Vertex plans to advance one or more novel small molecule zAAT correctors into the clinic in 2022.

Investments in External Innovation

To further expand our capabilities in gene editing, Vertex recently announced two new collaborations.

In August, Vertex announced a new collaboration with Arbor Biotechnologies Inc. to enhance efforts in developing ex vivo engineered cell therapies for multiple serious diseases using Arbor's proprietary CRISPR gene-editing technology.
In October, Vertex announced a new collaboration with Mammoth Biosciences to develop in vivo gene-editing therapies for two diseases using Mammoth's next-generation CRISPR systems.

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 (i) stock-based compensation expense, (ii) revenues and expenses related to collaborative upfront and milestones payments, including the $900 million upfront payment to CRISPR Therapeutics, and certain other business development activities, (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 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 adjusts, where appropriate, for both revenues and expenses in order to reflect the company's operations. 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 combined GAAP R&D and SG&A expenses does not include estimates associated with any potential future business development activities. 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.

Notes and Explanations

1: In the three and nine months ended September 30, 2021 and 2020, "Tax adjustments" included the estimated income taxes related to non-GAAP adjustments to the company's pre-tax income and non-recurring discrete benefits to the company's provision for income taxes. The estimated income taxes related to non-GAAP adjustments to the company's pre-tax income included adjustments for (i) stock-based compensation (including an adjustment for excess tax benefits related to stock-based compensation), (ii) changes in the fair value of the company's strategic investments and (iii) collaborative upfront and milestone payments and certain other business development activities and (iv) other adjustments. "Tax adjustments" in the nine months ended September 30, 2021 also included a $100 million discrete benefit related to an increase in the U.K.'s corporate tax rate from 19% to 25%, which was enacted in June 2021 and will become effective in April 2023. "Tax adjustments" in the nine months ended September 30, 2020 also included a $209 million discrete benefit related to the transfer of intellectual property rights to the company's U.K. entity, a $50 million discrete benefit related to the write-off of a long-term intercompany receivable and a $38 million discrete benefit related to an increase in the U.K.'s corporate tax rate from 17% to 19%, which was enacted and became effective in July 2020.

2: The difference between the company's full-year 2021 combined GAAP R&D and SG&A expenses and combined non-GAAP R&D and SG&A expenses guidance relates primarily to $1.0 billion to $1.1 billion of collaborative upfront and milestone payments and certain other business development activities related to existing business development agreements and $415 million to $445 million of stock-based compensation expense. The guidance regarding combined GAAP R&D and SG&A expenses does not include estimates associated with any potential future business development activities.

3: "Research and development expenses" include the $900 million upfront payment to CRISPR in the nine months ended September 30, 2021.

4: "Other income (expense), net" includes net gains related to changes in the fair value of the company's strategic investments and from sales of certain investments.

5: During the three and nine months ended September 30, 2021 and 2020, the change in the fair value of contingent consideration relates to potential payments to Exonics Therapeutics' former equity holders.

6: "Collaborative revenues and expenses" in the three and nine months ended September 30, 2021 and 2020 related to collaborative upfront and milestone payments and certain other business development activities. The company's $900 million upfront payment to CRISPR is included in "Collaborative revenues and expenses" during the nine months ended September 30, 2021.

7: "Acquisition-related costs" in the three and nine months ended September 30, 2021 and 2020 related to costs associated with the company's acquisition of Exonics Therapeutics in 2019.

8: The company released its valuation allowance on the majority of its net operating losses and other deferred tax assets as of December 31, 2018. As of December 31, 2020, the company had utilized substantially all of its remaining federal net operating losses. As a result, a larger portion of the company's tax provision represents a cash tax payable, subject to continued utilization of certain tax credits.
