ADC Therapeutics Provides Business Updates

 

ZYNLONTA®1 4Q 2023 net sales expected to be ~$16.5 million, a double-digit percentage increase as compared to 3Q 2023

 

LOTIS-7: Study of ZYNLONTA in combination with bispecifics cleared first dosing cohort   with no DLT and with early signs of efficacy

 

ADCT-601 (targeting AXL): Reached MTD and currently in dose optimization; Early signs of antitumor activity in both monotherapy and in combination

 

Multiple data catalysts expected in 2024 and with a cash runway now expected into 4Q 2025

 

Lausanne, Switzerland, January 4, 2024 – ADC Therapeutics SA (NYSE: ADCT) today provided business updates.

 

“During 2023, we took a number of decisive actions to help position the Company for success in 2024 and beyond. We prioritized our pipeline, strengthened our organization and implemented a disciplined capital allocation model to generate cost efficiencies,” said Ameet Mallik, Chief Executive Officer of ADC Therapeutics. “We believe we are starting to see signs of the commercial turnaround. We are also encouraged to see positive initial signals in the LOTIS-7 trial of ZYNLONTA in combination with bispecifics as well as early signs of antitumor activity in the Phase 1b trial of ADCT-601. We now expect our cash runway to extend into the fourth quarter of 2025 and believe we are on a path to unlock the substantial value in the Company.”

 

Recent Highlights and Developments

 

ZYNLONTA® (loncastuximab tesirine-lpyl)

 

ZYNLONTA net sales for the fourth quarter of 2023 are expected to be approximately $16.5 million.

 

The Phase 1 LOTIS-7 trial of ZYNLONTA in combination with bispecifics glofitamab or mosunetuzumab for the treatment of patients with diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) and marginal zone lymphoma (MZL) is actively enrolling patients. The dose-limiting toxicity (DLT) period has been cleared for the first dosing level of ZYNLONTA 90 µg/kg in both arms, and there have been no discontinuations due to adverse events (AEs). To date, each of the first five patients eligible for assessment in this dosing level has shown a response (partial response or complete response) at first scan.  

 

An oral presentation at the American Society of Hematology (ASH) 2023 Annual Meeting from the University of Miami investigator-initiated trial exploring ZYNLONTA in combination with rituximab in high-risk relapsed or refractory FL indicated a best overall response rate of 96.3% and a complete response rate of 85.2%  . After a median follow-up of 9.7 months, the median

 

 

(1)loncastuximab tesirine-lpyl; DLT: Dose-Limiting Toxicity; MTD: Maximum-Tolerated Dose

 

 

 

progression-free survival (PFS) was not reached, and the 12-month PFS was 92.3%  . The majority of AEs were grade 1. Grade 3 AEs included neutropenia (n=2; 6.2%), and one case each (3.1%) of hyperglycemia, increased ALT, fatigue, dyspnea and skin infection. Neutropenia was the only grade 4 AE (n=1; 3.1%).

 

Pipeline

 

ADCT-601 (targeting AXL): In the Phase 1b trial, the maximum-tolerated dose has been reached, and the study is currently in dose optimization. There have been early signs of antitumor activity in both monotherapy and in combination. The dose-optimization/ expansion phase is comprised of a monotherapy arm including patients with sarcoma, pancreatic cancer and AXL-expressing non-small cell lung cancer (NSCLC) and a combination arm with gemcitabine in patients with sarcoma and pancreatic cancer.

 

ADCT-901 (targeting KAAG1): The Company has decided to discontinue this program due to limited signs of efficacy in the dose escalation phase and to reallocate capital to prioritized programs.

 

ADCT-602 (targeting CD22): Dose escalation and expansion in the Phase 1 trial in collaboration with MD Anderson Cancer Center for patients with relapsed or refractory acute lymphoblastic leukemia is progressing, and additional clinical trial sites are being added to accelerate enrollment.

 

Early-stage pipeline: The Company is advancing a portfolio of investigational ADCs including those targeting Claudin-6, NaPi2b and PSMA. These candidates utilize exatecan with a novel hydrophilic linker as a highly potent and differentiated payload.

 

Balance Sheet

 

The Company ended the fourth quarter of 2023 with cash and cash equivalents of ~$278.5 million.

 

Guidance

 

The Company expects the following based on its current business plan:

 

Decrease in total operating expenses expected in full year 2023 and 2024 as compared to 2022

 

Cash runway expected into 4Q 20251 (previously: mid-2025)

 

Expected Milestones in 2024

 

ZYNLONTA

 

Achieve commercial brand profitability in 2024

 

LOTIS-5: Complete enrollment in 2024

 

LOTIS-7: Additional safety and efficacy data from the dose-escalation and dose-expansion portions of the Phase 1 study in 2024

 

 

(1)Cash runway assumes receipt of anticipated regulatory milestone payments under the Company’s collaboration agreements and use of the amount it is required to maintain under its loan agreement

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) 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.

 

About ADC Therapeutics

 

ADC Therapeutics (NYSE: ADCT) is a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs). The Company is advancing its proprietary ADC technology to transform the treatment paradigm for patients with hematologic malignancies and solid tumors.

 

 

 

ADC Therapeutics’ CD19-directed ADC ZYNLONTA (loncastuximab tesirine-lpyl) received accelerated approval by the FDA and conditional approval from the European Commission for the treatment of relapsed or refractory diffuse large B-cell lymphoma after two or more lines of systemic therapy. ZYNLONTA is also in development in combination with other agents and in earlier lines of therapy. In addition to ZYNLONTA, ADC Therapeutics has multiple ADCs in ongoing clinical and preclinical development.
