LAUSANNE, Switzerland, Nov. 02, 2023 (GLOBE NEWSWIRE) -- ADC Therapeutics SA (NYSE: ADCT) today announced abstracts on ZYNLONTA® (loncastuximab tesirine-lpyl) have been accepted for presentation at the 65th American Society of Hematology (ASH) Annual Meeting, which will be held in San Diego, California from December 9-12, 2023.
"We look forward to sharing insights from the growing body of research supporting the clinical utility of ZYNLONTA as a single agent and in combination with other treatments at the 65th ASH Annual Meeting,” said Mohamed Zaki, MD, PhD, Chief Medical Officer of ADC Therapeutics. “In addition, we are encouraged by the initial results of an investigator-initiated Phase 2 study evaluating ZYNLONTA in combination with rituximab in patients with relapsed or refractory follicular lymphoma.

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.
