ADC Therapeutics Reports Fourth Quarter and Full Year 2022 Financial Results and Provides Business Updates

LAUSANNE, Switzerland--(BUSINESS WIRE)-- ADC Therapeutics SA (NYSE: ADCT) today reported financial results for the fourth quarter and full year ended December 31, 2022, and provided business updates.

“We made good progress across the business in 2022, including laying the crucial groundwork for the ongoing ZYNLONTA launch. This year, we expect to grow ZYNLONTA net product sales by a double-digit percentage year-over-year. Beyond the 3L+ setting, ZYNLONTA’s differentiated product profile positions it as an attractive combination partner in earlier lines of therapy. This potential is actively being explored in numerous company-sponsored and independent trials, which, if successful, will help serve patients with unmet medical needs and could increase ZYNLONTA’s annual revenue potential to a range of $500 million to $1 billion in the future,” said Ameet Mallik, Chief Executive Officer of ADC Therapeutics.

“I believe our strengthened senior leadership team with substantial commercial and drug development experience will be critical in our transition to the next phase of growth and unlocking the tremendous value of the Company over time. Supported by a cash runway that is expected to extend into mid-2025, we believe we are well-positioned to execute our strategic imperatives in 2023 and beyond.”

Recent Highlights and Developments

ZYNLONTA (loncastuximab tesirine-lpyl)

• Revenue from the net sales of ZYNLONTA in the fourth quarter of 2022 increased to $19.8 million, a 16.5% increase over the same quarter in 2021, and $74.9 million for the full year 2022, partially offset by higher gross-to-net sales deductions. The sequential third quarter to fourth quarter slight decline of 7.0% in net sales was due to higher gross-to-net and individual ordering account fluctuations.
• The European Commission (EC) and the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) granted conditional marketing authorization for the use of ZYNLONTA (loncastuximab tesirine) for the treatment of relapsed or refractory diffuse large B-cell lymphoma (DLBCL).
• The Company entered into a collaboration and clinical supply agreement with Roche to evaluate ZYNLONTA in combination with glofitamab and mosunetuzumab in addition to polatuzumab in the Phase 1 LOTIS-7 trial.

Cami (camidanlumab tesirine)

• Based on the positive pivotal Phase 2 data, the Company is actively seeking a partner to progress this program.

Pipeline

• ADCT-901 (targeting KAAG1): Dose escalation in the Phase 1 single-agent trial is progressing. The Company is amending the protocol to explore different dosing schedules to optimize the potential clinical outcomes for patients and in preparation for regulatory interactions.

Guidance

The Company has set the following guidance based on its current business plan:

• Expected to grow ZYNLONTA FY 2023 net product sales by a double-digit percentage year-over-year. This includes a gross-to-net increase as compared to 2022 of:
  • Approximately 2 to 3 percentage points related to Group Purchasing Organization (GPO) contracting
  • Mid- to high-single-digit percentage points resulting from the Infrastructure Investment and Jobs Act’s requirement for manufacturers of certain single-source drugs separately paid for under Medicare Part B and marketed in single-dose containers to provide annual refunds for unused drug, effective January 1, 2023
• Anticipated decrease in total operating expenses in 2023 and 2024 as compared to 2022

Fourth Quarter and Full Year Financial Results

Cash and Cash Equivalents

Cash and cash equivalents were $326.4 million as of December 31, 2022, compared to $380.9 million as of September 30, 2022. This does not include the $50.0 million milestone received in February 2023 from Sobi, triggered by European regulatory approval of ZYNLONTA in third-line DLBCL. Based on the Company’s business plan and expected $75.0 million milestone from HealthCare Royalty Partners, triggered by the first EU commercial sale, the Company expects its cash runway now extends into the middle of 2025.

Product Revenue

Net product revenue was $19.8 million for the fourth quarter and $74.9 million for the full year ended 2022, compared to $17.0 million for the same quarter and $33.9 million for the full year ended 2021. Net product revenues are for U.S. sales of ZYNLONTA which commenced in May 2021. The 120.9% year-over-year increase was principally due to a full year of sales activity in 2022 as compared to a partial year in 2021. The increase in sales volume was partially offset with higher gross-to-net deductions.

License Revenue

License revenue was $50.0 million for the fourth quarter of 2022. The Company recognized $50.0 million from Sobi for the European regulatory approval of ZYNLONTA in third-line DLBCL. License revenue was $135.0 million for the full year 2022 and included the $50.0 million European regulatory approval milestone from Sobi, as well as $85.0 million in upfront payments from our partners, Sobi and Mitsubishi Tanabe Pharma Corporation.

Cost of Product Sales

Cost of product sales was $0.5 million for the fourth quarter and $4.6 million for the full year 2022, compared to $0.8 million for the same quarter and $1.4 million for the year full 2021. The increase of $3.2 million for the year was primarily associated with $2.5 million of impairment charges for product intermediates and antibodies that did not meet the Company’s specifications. The specification issues did not, and are not expected to, impact the Company’s ability to supply commercial product. In addition, cost of product sales increased due to a full year of sales activity in 2022 as compared to 2021 due to the commencement of ZYNLONTA sales in May 2021.

Research and Development (R&D) Expenses

R&D expenses were $48.7 million for the fourth quarter and $187.9 million for the full year 2022, compared to $42.5 million for the same quarter and $158.0 million for the full year 2021. R&D expenses increased as a result of continued investments in the pipeline.

Selling and Marketing (S&M) Expenses

S&M expenses were $16.2 million for the fourth quarter and $69.1 million for the full year 2022, as compared to $18.6 million for the same quarter and $64.8 million for the full year 2021. The decrease in S&M expenses for the quarter was primarily due to lower share-based compensation expense. The increase in S&M expenses during the year is primarily due to increased professional expenses relating to the commercial launch of ZYNLONTA during the year partially offset by lower share-based compensation expense.

General and Administrative (G&A) Expenses

G&A expenses were $15.1 million for the fourth quarter and $72.0 million for the full year 2022, compared to $17.9 million for the same quarter and $71.5 million for the full year. G&A expenses decreased during the fourth quarter primarily due to lower share-based compensation expense. G&A expenses for the full year increased primarily due to higher professional fees and costs associated with the CEO transition, partially offset by lower share-based compensation expense.

Net Loss and Adjusted Net Loss

Net loss was $24.2 million, or a net loss of $0.30 per basic and diluted share for the fourth quarter and $155.8 million, or a net loss of $1.99 per basic and diluted share for the year ended December 31, 2022. This compares to a net loss of $34.4 million, or a net loss of $0.45 per basic and diluted share, for the same quarter and $230.0 million, or a net loss of $3.00 per basic and diluted share, for the year ended December 31, 2021.

Adjusted net loss, which is a non-IFRS financial measure, was $7.9 million, or an adjusted net loss of $0.10 per basic and diluted share for the fourth quarter and $81.7 million, or an adjusted net loss of $1.05 per basic and diluted share for the full year ended December 31, 2022. This compares to an adjusted net loss of $30.0 million, or an adjusted net loss of $0.39 per basic and diluted share, for the same quarter and $186.1 million, or an adjusted net loss of $2.42 per basic and diluted share, for the year ended December 31, 2021.

The decrease in net loss and adjusted net loss for the quarter and year ended December 31, 2022, as compared to the same period in 2021, was primarily due to higher product and license revenue, partially offset by the increase in operating expenses. The decrease in net loss for the quarter and year-ended December 31, 2022 was also attributable to lower share-based compensation expense and income arising from changes in the fair value of our convertible loan derivatives and warrant obligations, offset by the extinguishment of our convertible loans and derivatives.

About ZYNLONTA^® (loncastuximab tesirine-lpyl)

ZYNLONTA^® is a CD19-directed antibody drug conjugate (ADC). Once bound to a CD19-expressing cell, ZYNLONTA is internalized by the cell, where enzymes release a pyrrolobenzodiazepine (PBD) payload. The potent payload binds to DNA minor groove with little distortion, remaining less visible to DNA repair mechanisms. This ultimately results in cell cycle arrest and tumor cell death.

The U.S. Food and Drug Administration (FDA) has approved ZYNLONTA (loncastuximab tesirine-lpyl) for the treatment of adult patients with relapsed or refractory (r/r) large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (NOS), DLBCL arising from low-grade lymphoma and also high-grade B-cell lymphoma. The trial included a broad spectrum of heavily pre-treated patients (median three prior lines of therapy) with difficult-to-treat disease, including patients who did not respond to first-line therapy, patients refractory to all prior lines of therapy, patients with double/triple hit genetics and patients who had stem cell transplant and CAR-T therapy prior to their treatment with ZYNLONTA. This indication is approved by the FDA under accelerated approval based on overall response rate and continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

ZYNLONTA is also being evaluated as a therapeutic option in combination studies in other B-cell malignancies and earlier lines of therapy.

Use of Non-IFRS Financial Measures

In addition to financial information prepared in accordance with IFRS, this document also contains certain non-IFRS financial measures based on management’s view of performance including:

• Adjusted net loss and income
• Adjusted net loss and income per share

Management uses such measures internally when monitoring and evaluating our operational performance, generating future operating plans and making strategic decisions regarding the allocation of capital. We believe that these adjusted financial measures provide useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and facilitate operating performance comparability across both past and future reporting periods. These non-IFRS measures have limitations as financial measures and should be considered in addition to, and not in isolation or as a substitute for, the information prepared in accordance with IFRS. When preparing these supplemental non-IFRS measures, management typically excludes certain IFRS items that management does not believe are indicative of our ongoing operating performance. Furthermore, management does not consider these IFRS items to be normal, recurring cash operating expenses; however, these items may not meet the IFRS definition of unusual or non-recurring items. Since non-IFRS financial measures do not have standardized definitions and meanings, they may differ from the non-IFRS financial measures used by other companies, which reduces their usefulness as comparative financial measures. Because of these limitations, you should consider these adjusted financial measures alongside other IFRS financial measures.

The following items are excluded from adjusted net loss and adjusted net loss per share:

Shared-Based Compensation Expense: We exclude share-based compensation expense from our adjusted financial measures because share-based compensation expense, which is non-cash, fluctuates from period to period based on factors that are not within our control, such as our stock price on the dates share-based grants are issued. Share-based compensation expense has been, and will continue to be for the foreseeable future, a recurring expense in our business and an important part of our compensation strategy.

Certain Other Items: We exclude certain other significant items that we believe do not represent the performance of our business, from our adjusted financial measures. Such items are evaluated by management on an individual basis based on both quantitative and qualitative aspects of their nature. While not all-inclusive, examples of certain other significant items excluded from our adjusted financial measures would be: changes in the fair value of derivatives and warrant obligations and the effective interest expense associated with the Facility Agreement with Deerfield and the senior secured term loan facility, loss on extinguishment, transaction costs associated with debt or equity issuances that are expenses pursuant to IFRS, and the effective interest expense and a cumulative catch-up adjustment associated with the deferred royalty obligation under the royalty purchase agreement with HealthCare Royalty Partners.

See the attached Reconciliation of IFRS Measures to Non-IFRS Measures for explanations of the amounts excluded and included to arrive at the non-IFRS financial measures.
