"Since assuming my new role a month ago, I am pleased with our progress to focus on our key strategic priorities and improve our operational performance in order to deliver exceptional results for patients and our investors," said Kenneth Galbraith, Zymeworks’ Chair and Chief Executive Officer. "During 2022 and 2023, we expect to deliver on a number of potential value-driving milestones across the organization through forming new partnerships and collaborations, accelerating enrollment of our two ongoing pivotal trials for zanidatamab, reporting data catalysts for both zanidatamab and ZW49, and showcasing new product candidates developed from our novel platforms."

Business Highlights and Recent Developments

Clinical Program Highlights

"This year will be important for progressing our two clinical-stage product candidates, including the reporting of additional clinical data on both zanidatamab and ZW49," said Neil Klompas, Zymeworks’ Chief Operating Officer. "We look forward to achieving full enrollment for our pivotal trial in BTC by the middle of 2022 and to sharing additional data on our two clinical-stage product candidates at major medical meetings over the course of the next year."

Zanidatamab Advances with Two Pivotal Trials.
HERIZON-GEA-01, a pivotal study evaluating zanidatamab in 1L HER2-positive GEA, continues to enroll patients based on confirmatory data presented in September 2021 at ESMO (Free ESMO Whitepaper) in the 1L GEA setting for zanidatamab in combination with chemotherapy. These data position zanidatamab as a potential new standard of care in the first-line setting, and enrollment for HERIZON-GEA-01 continues with plans to complete by the end of 2023. HERIZON-BTC-01, a pivotal study evaluating zanidatamab in previously-treated advanced HER2-amplified BTC, continues to enroll patients and we expect to complete enrollment by mid-2022.
Multiple data catalysts in 2022 to be presented at major medical meetings, including ASCO (Free ASCO Whitepaper).
Zymeworks, along with our partner BeiGene, has submitted abstracts to be presented at the 2022 ASCO (Free ASCO Whitepaper) Annual Meeting in June. Subject to acceptance of these abstracts, we look forward to sharing important new data from the clinical development program for zanidatamab. In addition, Zymeworks will host a conference call discussing results of these studies after the completion of the 2022 ASCO (Free ASCO Whitepaper) Annual Meeting.
ZW49 Continues to Advance Towards Clinical Data Readout in H2 2022.
Zymeworks’ second clinical-stage asset and first biparatopic HER2-targeting antibody-drug conjugate, ZW49, has completed enrollment of 30 patients in the expansion cohorts targeting 2.5 mg/kg every three weeks. The weekly dosing regimen continues to progress with no dose-limiting toxicities observed to date. We plan to present the results and recommended development path forward at a major medical meeting in the second half of 2022.
Continued Focus on Partnerships and Collaboration

We remain focused on driving value through executing new partnerships and collaborations to support the development of our clinical-stage product candidates, zanidatamab and ZW49, and advancing new antibody-drug conjugate (ADC) or multispecific product candidates based on our novel, next-generation multifunctional therapeutic platforms. We continue to prioritize partnerships and collaborations to fund our operations and further strengthen our financial position.

Throughout 2021 our partnerships continued to advance into the clinical setting, reflected by the receipt of milestone payments in conjunction with Janssen initiating clinical studies with two bispecific antibodies using the Azymetric and EFECT platforms, and BeiGene initiating the pivotal study, HERIZON-GEA-01, in its territory. In tandem, we recognized partnership revenues from the amendment of the Iconic/Exelixis sub-licensing agreement for a ZymeLink ADC. Zymeworks has multiple active collaborations with over $8 billion in potential milestone payments in addition to royalties on potential product sales and has received over $235 million to date.

Corporate Updates

We continue to deliver upon our previously announced cost-efficiency measures and reduction in workforce and expect to exceed our target of reducing employee headcount by at least 25% by March 1, 2022.

With a more focused and efficient workforce, combined with a reduction in operational expenses and the proceeds from our public offering that closed on January 31, we are updating our cash runway guidance into the second half of 2023. Additionally, as we realize additional efficiencies across the organization, and continue to execute on our partnering and monetization initiatives, we expect to be able to extend our cash runway further, and look forward to providing updates in further communications.

In addition, we are pleased to announce that effective immediately, Chris Astle, PhD will be promoted to Senior Vice President and Chief Financial Officer, joining our executive team. Mr. Klompas will continue in the role of Chief Operating Officer.

Chris joined the finance group at Zymeworks in 2021 after relocating from Seattle where he previously served as Vice President at Alder Pharmaceuticals (sold to Lundbeck in 2019 for $1.6 billion). He began his career in the UK, including holding financial positions with Allergan and Gilead. Chris is a Chartered Accountant in the UK and holds a PhD in organic chemistry from the University of Bristol.

"I am thrilled to continue working with Chris in his new position as Senior Vice President and CFO," said Neil Klompas, Chief Operating Officer. "Following the successful hand off of the CFO role, one I have held since 2007, our senior management team will be better positioned to focus on delivering results against the key strategic priorities of our business. We look forward to reporting to our investors on our performance in the weeks and months ahead."

Financial Results for the Year Ended December 31, 2021

Zymeworks’ revenue relates primarily to non-recurring upfront fees, expansion payments or milestone payments from collaboration and license agreements, which can vary in timing and amount from period to period, as well as payments for research and development support. Revenue was $26.7 million in 2021 compared to $39.0 million in 2020. Revenue for 2021 included $8.0 million from BeiGene for a development milestone, $8.0 million from Janssen for two development milestones, $5.0 million from Iconic for partner revenue and $5.7 million from our partners for research and development support under cost sharing arrangements. Revenue for 2020 included $15.0 million from BeiGene for development milestones, $12.0 million from BMS for an expansion fee, $4.0 million from Iconic for partner revenue and $8.0 million from our partners for research and development support under cost sharing arrangements.

We anticipate continuing to receive revenue from our existing and future strategic partnerships, including technology access fees and milestone-based payments. However, our ability to receive these payments is dependent upon either Zymeworks or our collaborators successfully completing specified research and development activities.

Research and development expense was $199.8 million in 2021 compared to $171.2 million in 2020. The increase was primarily due to higher salary and benefit expenses from additional headcount, as well as an increase in zanidatamab clinical trials and other preclinical and research and development expenses which were partially offset by a decrease in drug manufacturing activities. Research and development expenses in 2021 included non-cash stock-based compensation expense of $20.1 million from equity-classified equity awards and a $4.6 million recovery from the non-cash mark-to-market revaluation of certain historical liability-classified equity awards. Excluding stock-based compensation, research and development expenses increased on a non-GAAP basis by $25.4 million for the year ended December 31, 2021 compared to 2020.

We expect research and development expenditures to fluctuate over time in line with the advancement, expansion and completion of the clinical development of our product candidates, as well as our ongoing preclinical research activities.

General and administrative expense was $42.6 million in 2021 compared to $55.2 million in 2020. General and administrative expense included non-cash stock-based compensation expense of $18.2 million from equity-classified equity awards and a $23.8 million recovery from the non-cash mark-to-market revaluation of certain historical liability-classified equity awards. Excluding stock-based compensation expense, general and administrative expense increased on a non-GAAP basis by $9.1 million year over year primarily due to higher salary and benefit expenses from additional headcount, and professional fees, partially offset by a U.S. state sales tax refund recognized in 2021.

In January 2022, we announced that future spending will be focused on our key strategic priorities. In response to this focusing of priorities, we also announced a reduction in workforce of at least 25% to be achieved by the end of 2022. We expect the prioritization and reduction in workforce should result in lower overall spending levels for 2022 and 2023, after accounting for restructuring costs.

Net loss was $211.8 million in 2021 compared to $180.6 million in 2020. The increase in net loss was primarily due to the increases in research and development expenses and decrease in revenue and interest income partially offset by lower general and administrative expense.

As of December 31, 2021, Zymeworks had $252.6 million in cash resources consisting of cash, cash equivalents and short-term investments, which excludes $107.6 million in net proceeds received from our public offering that closed on January 31, 2022. Based on our current operating plan, we believe that our current cash resources, in combination with the anticipated cost savings from the reduction in workforce, proceeds from our public offering, and proceeds from other collaboration payments we anticipate receiving, will enable us to fund our planned operations into the second half of 2023 and potentially beyond.

Zentalis Pharmaceuticals Reports Fourth Quarter and Full Year 2021 Financial Results and Operational Update

"In 2021, we made significant headway advancing the development of our programs, culminating in an R&D Day in December where we highlighted key updates to our pipeline," commented Dr. Anthony Sun, Chairman and Chief Executive Officer of Zentalis. "At the R&D Day, we discussed the addition of new capabilities to our Integrated Discovery Engine, reinforced ZN-c3 as the cornerstone of our value proposition and provided evidence supporting ZN-c5 and ZN-d5’s potential as differentiated oncology agents. Additionally, we unveiled a new candidate—a preclinical heterobifunctional degrader targeting BCL-xL—which is expected to enter IND-enabling studies this year. We continue to be guided by our expertise in medicinal chemistry, cancer biology and technology to generate best-in-class treatments and look forward to achieving our upcoming milestones across our portfolio in 2022."

Program Highlights:

In December 2021, Zentalis’ management team, along with three Key Opinion Leaders, held a virtual Research and Development Day. Specific highlights include: the addition of a preclinical BCL-xL heterobifunctional degrader candidate to its pipeline; the initiation of two additional studies with ZN-c3; the preclinical exploration of ZN-c3 into breast cancer, colorectal cancer and immunotherapy combinations; preliminary efficacy data of ZN-d5 in diffuse large B-cell lymphoma and acute myeloid leukemia; and ZN-c5’s differentiated safety and tolerability profile in breast cancer patients.
In November 2021, the FDA granted Fast Track designation to ZN-c3 for the treatment of recurrent or persistent USC. The potentially registrational Phase 2 trial of ZN-c3 in USC is underway, with an initial enrollment and safety update expected in the second half of 2022.
In December 2021, the Company presented a poster at the San Antonio Breast Cancer Symposium, held from December 7-10, 2021. The poster provided an updated interim analysis from the Phase 1/2 trial of its oral SERD, ZN-c5, in combination with palbociclib (marketed as Ibrance by Pfizer) in ER+/HER2- advanced breast cancer.
Fourth Quarter and Full Year 2021 Financial Results

Cash and Marketable Securities Position: As of December 31, 2021, Zentalis had cash, cash equivalents and marketable securities of $339.9 million. The Company believes that its existing cash, cash equivalents and marketable securities as of December 31, 2021 will be sufficient to fund its operating expenses and capital expenditures requirements into the third quarter of 2023.
Research and Development Expenses: Research and development expenses for the year ended December 31, 2021 were $175.6 million, compared to $84.9 million for the year ended December 31, 2020. The increase was primarily due to increases in external research and development expenses related to Zentalis’ lead product candidates, as the Company advanced its clinical pipeline in 2021. In addition, in 2021, Zentalis conducted additional preclinical studies, incurred additional manufacturing costs, and incurred increased costs for study and lab materials.
General and Administrative Expenses: General and administrative expenses for the year ended December 31, 2021 were $40.9 million, compared to $33.9 million during the year ended December 31, 2020. The increase was primarily attributable to an increase of $8.7 million in employee-related costs, of which $4.5 million was driven by non-cash stock-based compensation from incentive grants issued during the period and increased headcount to support its growth.

"We continue to make strong progress with patient growth as we march toward our target of reaching 25,000 patients with our therapies by the end of 2025," said Martine Rothblatt, Ph.D., Chairperson and Chief Executive Officer of United Therapeutics. "The recent transplants of our xenoheart and xenokidney products demonstrate the tremendous potential of our business model for the second half of the 2020s and beyond. Indeed, Mr. David Bennett, Sr., the first UHeart recipient, continues to have strong cardiovascular function seven weeks after his transplant."

"Our commercial teams continue to perform with double-digit percentage growth in revenue and patient counts in 2021 compared to 2020," said Michael Benkowitz, President and Chief Operating Officer of United Therapeutics. "Despite a setback with Tyvaso DPI, we remain on track to achieve 6,000 patients with Tyvaso by the end of 2022."

United Therapeutics recently received an information request letter from the U.S. Food and Drug Administration (FDA) requesting additional information regarding the pulmonary safety of Tyvaso DPI related to a pending Citizen’s Petition. United Therapeutics responded to the agency’s information request; however, the FDA has considered this response to be a major amendment to the NDA, extending FDA’s review deadline to May 2022.

FOURTH QUARTER AND FULL YEAR 2021 FINANCIAL RESULTS

(1) See definition of non-GAAP earnings, a non-GAAP financial measure, and a reconciliation of net income to non-GAAP earnings below.

Revenues

The table below summarizes the components of total revenues (dollars in millions):

Net product sales from our treprostinil-based products (Tyvaso, Remodulin, and Orenitram) grew by $23.5 million in the fourth quarter of 2021 compared to the fourth quarter of 2020. The growth in Tyvaso revenues resulted primarily from an increase in quantities sold, reflecting an increased number of patients following the expansion of the Tyvaso label to include pulmonary hypertension associated with interstitial lung disease (PH-ILD). The decrease in Remodulin revenues was primarily due to lower quantities sold in the U.S. The growth in Unituxin revenues primarily resulted from an increase in quantities sold. Unituxin revenues in the fourth quarter of 2021 included $6.3 million related to the launch of Unituxin in Japan.

Net product sales from our treprostinil-based products (Tyvaso, Remodulin, and Orenitram) grew by $134.2 million in 2021 compared to 2020. The growth in Tyvaso revenues resulted primarily from an increase in quantities sold, reflecting an increased number of patients following the PH-ILD label expansion and, to a lesser extent, price increases. The decrease in Remodulin revenues resulted from a decrease in U.S. Remodulin revenues of $28.9 million, partially offset by an increase in international Remodulin revenues of $25.9 million. The decrease in U.S. Remodulin revenues was primarily due to a decrease in quantities sold and, to a lesser extent, higher gross-to-net deductions. The increase in international Remodulin revenues was primarily due to reduced orders by an international distributor in 2020 in order to reduce its inventory as a result of the anticipated impact of generic competition. The growth in Unituxin revenues resulted from an increase in quantities sold and, to a lesser extent, price increases. Unituxin revenues in 2021 included $18.4 million related to the launch of Unituxin in Japan.

Cost of product sales, excluding share-based compensation. The increase in cost of product sales for the year ended December 31, 2021, as compared to the same period in 2020, was primarily attributable to shipments of the Remunity Pump following launch in February 2021.

Research and development expense. The table below summarizes research and development expense by major category (dollars in millions):

Research and development expense, excluding share-based compensation. The decrease in research and development expense for the quarter ended December 31, 2021, as compared to the same period in 2020, was due to: (1) a decrease in milestone payments under our license and collaboration agreement with MannKind; (2) a decrease in pre-launch costs related to the Remunity Pump launch; and (3) a decrease in spending related to a facility we decided to repurpose in 2021.

The increase in research and development expense for the year ended December 31, 2021, as compared to the same period in 2020, was due to: (1) a $107.3 million IPR&D impairment charge related to our March 2021 decision to discontinue the U.S. development of Trevyent; (2) a $105.0 million purchase of a pediatric disease priority review voucher, which we redeemed upon submission of the Tyvaso DPI new drug application (NDA); and (3) an $11.6 million impairment charge related to repurposing one of our facilities. These increases were partially offset by a decrease in milestone payments under our license and collaboration agreement with MannKind and reduced costs following the completion of the phase 3 DISTINCT study of Unituxin in 2020.

Selling, general, and administrative expense. The table below summarizes selling, general, and administrative expense by major category (dollars in millions):

General and administrative, excluding share-based compensation. The increase in general and administrative expense for the year ended December 31, 2021, as compared to the same period in 2020, was primarily due to: (1) an increase in litigation expenses; and (2) an increase in consulting expenses.

Share-based compensation. The table below summarizes share-based compensation expense by major category (dollars in millions):

The decrease in share-based compensation expense for the quarter and year ended December 31, 2021, as compared to the same periods in 2020, was due to a decrease in STAP expense driven by a 17 percent increase and a 42 percent increase in our stock price during the quarter and year ended December 31, 2021, respectively, as compared to a 50 percent increase and a 72 percent increase in our stock price for the quarter and year ended December 31, 2020, respectively. There was also a decrease in stock option expense for the year ended December 31, 2021 due to a reduction in awards granted and outstanding in 2021 compared to the same period in 2020. The decrease in share-based compensation expense for the year ended December 31, 2021 was partially offset by an increase in restricted stock unit expense.

Other (expense) income, net. The changes in other (expense) income, net for the quarter and year ended December 31, 2021, as compared to the same periods in 2020, were primarily due to the recognition of net unrealized and realized gains and losses on our investments in equity securities and net unrealized gains and losses on our contingent consideration assets.

Income tax expense. Income tax expense was $118.1 million for the year ended December 31, 2021, as compared to $124.1 million for the same period in 2020. For the years ended December 31, 2021 and 2020, our effective income tax rates (ETR) were approximately 20 percent and 19 percent, respectively. Our ETR for the year ended December 31, 2021 increased, as compared to our ETR for the year ended December 31, 2020, primarily due to increases in blended state income tax rates and decreases in tax credits, partially offset by a decrease in the valuation allowance on deferred taxes.

Non-GAAP Earnings

Non-GAAP earnings is defined as net income, adjusted for: (1) share-based compensation expense (including expenses relating to stock options, restricted stock units, share tracking awards, and our employee stock purchase plan); (2) unrealized gains on investments in privately-held companies; (3) impairment charges; (4) license-related fees; (5) net changes in recurring fair value measurements; (6) certain other costs incurred outside our normal course of business; and (7) tax impact on non-GAAP earnings adjustments.

(2) Recorded within other (expense) income, net in our consolidated statements of operations.

(3) For the quarter ended December 31, 2021, we recognized a $1.0 million impairment charge which was recorded within selling, general, and administrative in our consolidated statements of operations. For the year ended December 31, 2021, we recognized $134.9 million in impairment charges and recorded these charges within research and development, selling, general, and administrative, and impairments of investments in privately-held companies in our consolidated statements of operations. For the year ended December 31, 2020, we recognized impairment charges of $16.0 million and recorded these charges within impairments of investments in privately-held companies, selling, general, and administrative, and other (expense) income, net in our consolidated statements of operations.

(4) Recorded within research and development in our consolidated statements of operations.

(5) Net changes in the fair values of our contingent consideration liabilities were recorded within research and development in our consolidated statements of operations and net changes in all other recurring fair value measurements were recorded within other (expense) income, net in our consolidated statements of operations.

(6) For the year ended December 31, 2021, we expensed $105.0 million related to a pediatric disease priority review voucher and recorded the amount within research and development in our consolidated statements of operations.

PRODUCT COMMERCIALIZATION UPDATE

In 2021, we launched one new product and one new product indication. In February 2021, we launched commercial sales of the Remunity Pump for Remodulin, and in April 2021, we launched a label expansion for Tyvaso to include an indication for PH-ILD following approval by the U.S. FDA on March 31, 2021.

Remunity Pump for Remodulin. In February 2021, we launched sales of the Remunity Pump for Remodulin. The Remunity Pump is a pre-filled, semi-disposable system for subcutaneous delivery of treprostinil. The system consists of a small, lightweight, durable pump and separate controller. The pump uses disposable cartridges filled with Remodulin, which can be connected to the pump with less patient manipulation than is typically involved in filling other currently-available subcutaneous pumps.

Tyvaso Inhalation Solution in PH-ILD. The FDA approved Tyvaso for the PH-ILD indication on March 31, 2021, and we launched commercial efforts for the new indication shortly thereafter.

Tyvaso DPI. In April 2021, we submitted a new drug application (NDA) for Tyvaso DPI for pulmonary arterial hypertension (PAH) and PH-ILD indications. In October 2021 we received a complete response letter (CRL) from the FDA noting a single deficiency preventing approval of Tyvaso DPI, related to an open inspection issue at a third-party facility that performs analytical testing of treprostinil drug substance. The CRL noted, but did not cite as a deficiency, that the FDA had not yet completed its review of a Citizen Petition submitted to the FDA in July 2021 concerning the safety of an excipient in Tyvaso DPI.

We resubmitted our NDA in December 2021 and the FDA issued an action date for February 2022. In February 2022, the FDA requested additional information concerning the pulmonary safety of Tyvaso DPI related to a pending Citizen’s Petition. We responded to the FDA’s request, and the FDA indicated that our response constitutes a major amendment to the Tyvaso DPI NDA, which extends the FDA’s anticipated deadline to review the pending NDA to May 2022.

Our Tyvaso DPI NDA includes the results of two clinical studies we conducted of Tyvaso DPI. One was a study in healthy volunteers, comparing the pharmacokinetics of Tyvaso DPI to Tyvaso Inhalation Solution. The study was completed in October 2020, and demonstrated comparable systemic treprostinil exposure between Tyvaso DPI and Tyvaso Inhalation Solution. In December 2020, we completed a clinical study (called BREEZE), which evaluated the safety and pharmacokinetics of switching PAH patients from Tyvaso Inhalation Solution to Tyvaso DPI. The BREEZE study demonstrated the safety and tolerability of Tyvaso DPI in subjects with PAH transitioning from Tyvaso Inhalation Solution, and comparable systemic treprostinil exposure between Tyvaso DPI and Tyvaso Inhalation Solution.

RESEARCH AND DEVELOPMENT UPDATE

Updates on select later-stage programs are below.

Tyvaso in chronic fibrosing interstitial lung diseases — TETON 1 and TETON 2. We are enrolling a phase 3 study called TETON 1, which is a U.S. study of Tyvaso in patients with idiopathic pulmonary fibrosis (IPF). The primary endpoint of this study is the change in absolute forced vital capacity (FVC) from baseline to week 52. We are planning an additional phase 3 study of Tyvaso in IPF patients that will be similar to TETON 1, called TETON 2, but will be conducted outside the United States.

The TETON program was prompted by data from the INCREASE study, which demonstrated improvements in certain key parameters of lung function in pulmonary hypertension patients with fibrotic lung disease. Specifically, in the INCREASE study, treatment with Tyvaso resulted in significant improvements in percent predicted FVC at weeks 8 and 16, with subjects having underlying etiologies of idiopathic interstitial pneumonias showing greater improvement. Consistent positive effects were also observed in patients with chronic hypersensitivity pneumonitis and environmental/occupational lung disease. These data points, combined with substantial preclinical evidence of antifibrotic activity of treprostinil, suggest that Tyvaso may offer a treatment option for patients with fibrotic lung disease.

Tyvaso in PH-COPD — PERFECT. Enrollment is ongoing for the phase 3 PERFECT study evaluating Tyvaso in patients with WHO Group 3 pulmonary hypertension associated with chronic obstructive pulmonary disease (PH-COPD). In a 30-week crossover study, 136 subjects will be randomized between inhaled treprostinil and placebo for a 26-week treatment period. The primary endpoint of the study is the change in 6MWD from baseline to week 12.

Ralinepag phase 3 clinical studies — ADVANCE CAPACITY and ADVANCE OUTCOMES. We are enrolling two phase 3 clinical studies to support the potential approval of oral ralinepag for PAH.

INDUCEMENT RESTRICTED STOCK UNITS

On February 18, 2022, we granted a total of 570 restricted stock units under our 2019 Inducement Stock Incentive Plan to four newly hired employees. These restricted stock units vest in three equal installments on February 28, 2023, February 28, 2024, and February 28, 2025, assuming continued employment on such dates, and are subject to the standard terms and conditions we filed with the SEC as Exhibit 10.2 to our Current Report on Form 8-K on March 1, 2019. We are providing this information in accordance with Nasdaq Listing Rule 5635(c)(4).

UNITED THERAPEUTICS: ENABLING INSPIRATION

We build on the strength of our research and development expertise and a distinctive, entrepreneurial culture that encourages diversity, innovation, creativity, sustainability, and, simply, fun. Since inception, our mission has been to find a cure for pulmonary arterial hypertension and other life-threatening diseases. Toward this goal we have successfully gained FDA approval for five medicines, we are always conducting new clinical trials, and we are working to create an unlimited supply of manufactured organs for transplantation.

We are the first publicly-traded biotech or pharmaceutical company to take the form of a public benefit corporation (PBC). Our public benefit purpose is to provide a brighter future for patients through (a) the development of novel pharmaceutical therapies; and (b) technologies that expand the availability of transplantable organs. At the same time, we seek to provide our shareholders with superior financial performance and our communities with earth-sensitive energy utilization.
