Company to host conference call today at 8:30 a.m. EST

LAUSANNE, Switzerland, Nov. 7, 2024 /PRNewswire/ -- ADC Therapeutics SA (NYSE: ADCT), a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs), today reported financial results for the third quarter ended September 30, 2024, and provided recent operational updates.

"We are excited about the advancements in our ZYNLONTA(®) trials in earlier lines of diffuse large B-cell lymphoma therapy and look forward to reporting more on the combination with glofitamab in our LOTIS-7 trial, as well as reaching the expected full enrollment in LOTIS-5 before year-end," said Ameet Mallik, Chief Executive Officer of ADC Therapeutics. "We are discontinuing ADCT-601 targeting AXL and will prioritize our exatecan-based platform for solid tumors moving forward. With our expected cash runway into mid-2026, we believe we are well positioned to execute our strategy and advance multiple value-generating catalysts going forward."

Third Quarter 2024 Operational Updates & Recent Highlights

    --  Full enrollment expected by year-end in LOTIS-5. Enrollment for the
        Phase 3 confirmatory trial evaluating ZYNLONTA in combination with
        rituximab in patients with 2L+ diffuse large B-cell lymphoma (DLBCL) is
        expected to be completed by year-end 2024 with a data update expected in
        late 2025 once the pre-specified number of events is reached.


    --  LOTIS-7 enrollment continues with expected interim data update in
        December 2024. Enrollment continued in the Part 2 dose expansion of
        LOTIS-7, a Phase 1b open-label clinical trial evaluating ZYNLONTA in
        combination with the bispecific antibody glofitamab in patients with
        relapsed or refractory DLBCL. An interim update on safety and efficacy
        in a subset of patients is expected in December with additional data
        anticipated in the first half of 2025.
    --  Abstracts accepted for presentation at the 66(th) American Society of
        Hematology Annual Meeting 2024. Updated data from the
        investigator-initiated Phase 2 clinical trial, conducted at the
        Sylvester Comprehensive Cancer Center at the University of Miami Miller
        School of Medicine, evaluating ZYNLONTA in combination with rituximab in
        patients with relapsed or refractory follicular lymphoma will be shared
        during an oral presentation titled, "Loncastuximab tesirine with
        rituximab induces robust and durable complete metabolic responses in
        high-risk relapsed/refractory follicular lymphoma" (Abstract #337) on
        December 7, 2024 at 4 p.m. PT.

Updated data from the investigator-initiated Phase 2 clinical trial, conducted at the Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine, evaluating ZYNLONTA for the treatment of relapsed or refractory marginal zone lymphoma (MZL) will be presented during a poster presentation titled, "Limited duration loncastuximab tesirine induces a high rate of complete responses in patients in relapsed/refractory marginal zone lymphoma - report of first planned interim futility analysis of a multicenter Phase II study" (Abstract #3032) on December 8, 2024 from 6 - 8 p.m. PT.

    --  Discontinuation of ADCT-601 program targeting AXL. Based on the
        available clinical data and capital requirements for continued
        development, the Company will discontinue the Phase 1b ADCT-601 program
        targeting AXL as a single agent and/or in combination for patients with
        sarcoma, pancreatic cancer and non-small cell lung cancer. Although
        early signs of antitumor activity were observed during the dose
        escalation phase, we were unable to demonstrate a favorable benefit-risk
        profile during the dose optimization/expansion phase.


    --  ADCT-602 targeting CD22 dose escalation progressing. The Phase 1/2
        clinical trial, sponsored by The University of Texas MD Anderson Cancer
        Center, evaluating ADCT-602 in patients with relapsed or refractory
        B-cell acute lymphoblastic leukemia continues to progress and dose
        escalation continues at 60 µg/kg dose.
    --  IND-enabling studies ongoing in early-stage pipeline. Progress continues
        in the Investigational New Drug (IND) enabling studies for the Company's
        exatecan-based programs for ADCs targeting Claudin-6, PSMA and NaPi2b,
        while our ASCT2 targeting ADC is in the drug candidate selection stage.
        The Company has selected one target to move toward IND which is expected
        to be disclosed in 2025.

Third Quarter and Year-to-Date 2024 Financial Results

    --  Product Revenues: ZYNLONTA generated net product revenues of $18.0
        million for the third quarter ended September 30, 2024 and $52.9 million
        for the first nine months of 2024 as compared to $14.3 million and $52.4
        million for the same periods in 2023. The quarter-over-quarter increase
        is driven by higher sales volume, a higher selling price and lower
        gross-to-net deductions. The year-to-date increase is primarily
        attributable to a higher price, partially offset by lower sales volume.


    --  Research and Development (R&D) Expense: R&D expense was $32.5 million
        and $82.5 million for the three and nine months ended September 30,
        2024, respectively. This compares to R&D expense of $27.1 million and
        $96.8 million for the same periods in 2023.  The increase during the
        three months ended September 30, 2024 is due primarily to focused
        investment in prioritized development programs, including ADCT-601 and
        ZYNLONTA. The decrease during the nine months ended September 30, 2024
        is due primarily to the implementation of productivity initiatives and
        focused investment in prioritized development programs.


    --  Selling and Marketing (S&M) Expense: S&M expense was $10.7 million and
        $32.8 million for the three and nine months ended September 30, 2024,
        respectively. This compares to S&M expense of $13.7 million and $43.5
        million for the same periods in 2023. The decreases in S&M expense were
        primarily due to lower marketing and advertising costs and personnel
        related expenses.


    --  General & Administrative (G&A) Expense: G&A expense was $10.0 million
        and $32.3 million for the three and nine months ended September 30,
        2024, respectively. This compares to G&A expense of $9.6 million and
        $37.1 million for the same periods in 2023. The quarter-over-quarter
        increase in G&A expense was primarily related to higher personnel
        related expenses, partially offset by lower insurance costs while the
        year-to-date decrease was primarily related to lower personnel related
        expenses as well as lower insurance and IT expenses.


    --  Net Loss: Net loss for the quarter ended September 30, 2024 was $44.0
        million, or a net loss of $0.42 per basic and diluted share, as compared
        to net loss of $46.7 million, or a net loss of $0.57 per basic and
        diluted share for the same period in 2023. Net loss for the nine months
        ended September 30, 2024 was $127.1 million, or a net loss of $1.35 per
        basic and diluted share, as compared to net loss of $155.0 million, or a
        net loss of $1.90 per basic and diluted share for the nine months ended
        September 30, 2023. The decrease for the three months ended September
        30, 2024 is primarily related to higher revenues and a lower equity in
        net loss of our joint venture partially offset by higher operating
        expenses. The decrease for the nine months ended September 30, 2024 is
        primarily due to lower operating expenses.


    --  Adjusted Net Loss: Adjusted net loss, which is a non-GAAP financial
        measure, was $29.4 million, or an adjusted net loss of $0.28 per basic
        and diluted share for the quarter ended September 30, 2024 as compared
        to adjusted net loss of $32.4 million, or $0.39 per basic and diluted
        share, for the same period in 2023. Adjusted net loss for the nine
        months ended September 30, 2024 was $84.9 million, or an adjusted net
        loss of $0.90 per basic and diluted share, as compared to net loss of
        $106.3 million, or an adjusted net loss of $1.30 per basic and diluted
        share for the nine months ended September 30, 2023. The decrease in
        adjusted net loss for the three months ended September 30, 2024 is
        primarily related to higher revenues and a lower equity in net loss of
        our joint venture partially offset by higher operating expenses. The
        decrease in adjusted net loss for the nine months ended September 30,
        2024 is primarily attributable to lower operating expenses.
    --  Cash and cash equivalents: As of September 30, 2024, cash and cash
        equivalents were $274.3 million, compared to $278.6 million as of
        December 31, 2023. In May 2024 the Company completed an underwritten
        offering resulting in net proceeds of approximately $97.4 million,
        extending the expected cash runway into mid-2026.

About ZYNLONTA(®)
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) and the European Medicines Agency (EMA) have 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 and in the European Union under conditional 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. Please see full prescribing information including important safety information about ZYNLONTA at www.ZYNLONTA.com.

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-GAAP Financial Measures
In addition to financial information prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP), this document also contains certain non-GAAP financial measures based on management's view of performance including:

    --  Adjusted total operating expenses
    --  Adjusted net loss
    --  Adjusted net loss 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-GAAP 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 GAAP. When preparing these supplemental non-GAAP measures, management typically excludes certain GAAP items that management does not believe are indicative of our ongoing operating performance. Furthermore, management does not consider these GAAP items to be normal, recurring cash operating expenses; however, these items may not meet the GAAP definition of unusual or non-recurring items. Since non-GAAP financial measures do not have standardized definitions and meanings, they may differ from the non-GAAP 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 GAAP financial measures.

The following items are excluded from adjusted total operating expenses:

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.

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 warrant obligations and the effective interest expense associated with the senior secured term loan facility and the effective interest expense and cumulative catch-up adjustments associated with the deferred royalty obligation under the royalty purchase agreement with HealthCare Royalty Partners.

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

     (i)   Share-based compensation expense represents the cost of equity awards issued to our directors, management and
            employees. The fair value of awards is computed at the time the award is granted and is recognized over the
            requisite service period less actual forfeitures by a charge to the statement of operations and a corresponding
            increase in additional paid-in capital within equity. These accounting entries have no cash impact.


     (ii)  Change in the fair value of the Deerfield warrant obligation results from the valuation at the end of each accounting
            period. There are several inputs to these valuations, but those most likely to result in significant changes to the
            valuations are changes in the value of the underlying instrument (i.e., changes in the price of our common shares)
            and changes in expected volatility in that price. These accounting entries have no cash impact.


     (iii) Effective interest expense on senior secured term loans relates to the increase in the value of our loans in
            accordance with the amortized cost method.


     (iv)  Deferred royalty obligation interest expense relates to the accretion expense on our deferred royalty obligation
            pursuant to the royalty purchase agreement with HCR and cumulative catch-up adjustments related to changes in the
            expected payments to HCR based on a periodic assessment of our underlying revenue projections.
