168 0 Kommentare ADC Therapeutics Presents Updated ZYNLONTA (loncastuximab tesirine-lpyl) Clinical Data at 16th Annual International Conference on Malignant Lymphoma

ADC Therapeutics SA (NYSE:ADCT), a commercial-stage biotechnology company leading the development of novel antibody drug conjugates (ADCs) to treat hematological malignancies and solid tumors, announced today that posters on four ZYNLONTA (loncastuximab tesirine-lpyl) clinical trials were presented at the 16^th Annual International Conference on Malignant Lymphoma (ICML).

“The updated results from our pivotal LOTIS-2 clinical trial presented at ICML continue to reinforce the efficacy across difficult-to-treat subgroups and sustained duration of response of commercially-available ZYNLONTA as a single agent for patients with relapsed or refractory diffuse large B-cell lymphoma,” said Jay Feingold, MD, PhD, Senior Vice President and Chief Medical Officer of ADC Therapeutics. “We’re also pleased that the updated data from the LOTIS-3 clinical trial demonstrate the encouraging antitumor activity and manageable toxicity profile of ZYNLONTA in combination with ibrutinib in patients with relapsed or refractory DLBCL or mantle cell lymphoma. We look forward to continued progress in all of our LOTIS trials, including the ongoing LOTIS-5 trial of ZYNLONTA in combination with rituximab and LOTIS-6 trial in patients with relapsed or refractory follicular lymphoma.”

LOTIS-2 Follow-up Analysis (Poster 177)

In LOTIS-2, a single-arm, open-label, 145-patient Phase 2 clinical trial in patients with relapsed or refractory DLBCL who had failed ≥2 established therapies, ZYNLONTA demonstrated continued substantial antitumor activity and an acceptable safety profile. Updated results were presented in a poster by Pier Luigi Zinzani, MD, PhD, IRCCS Azienda Ospedaliero-Universitaria di Bologna Istituto di Ematologia "Seràgnoli", and Dipartimento di Medicina Specialistica, Diagnostica e Sperimentale Università di Bologna, Bologna, Italy. As of the data cut-off date of March 1, 2021, all patients had completed treatment.

Key data include:

Overall response rate (ORR) was 48.3% and complete response rate (CRR) was 24.8%
Median duration of response (mDoR) of 13.4 months for the 70 responders
Median duration of response not reached for patients with a complete response
Median overall survival was 9.5 months
No new safety concerns were identified during the study and no increase in toxicity was observed in patients aged ≥65 years compared with patients <65 years. The most common grade ≥3 treatment-emergent adverse events (TEAEs) were neutropenia (26.2%), thrombocytopenia (17.9%), increased gamma-glutamyltransferase (17.2%), and anemia (10.3%)
