100 r/r DLBCL patients treated at the selected 150 µg/kg dose of ZYNLONTA® plus glofitamab

Full data expected in fourth quarter of 2026

LAUSANNE, Switzerland, June 30, 2026 /PRNewswire/ -- ADC Therapeutics SA (NYSE:ADCT), a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs), today announced the completion of enrollment in the LOTIS-7 Phase 1b open-label clinical trial evaluating the safety and efficacy of ZYNLONTA® (loncastuximab tesirine-lpyl) in combination with the bispecific antibody glofitamab (COLUMVI®) in patients with relapsed or refractory (r/r) diffuse large B-cell lymphoma (r/r DLBCL).

LOTIS-7 trial enrollment is now complete with 100 r/r DLBCL patients dosed at the selected 150 µg/kg dose of ZYNLONTA plus glofitamab. Enrollment occurred in 30 total sites with 70% of patients in the US and 30% in the EU. The study enrolled patients with baseline characteristics similar to other bispecific combination studies in this space and included 46% relapsed and 54% primary refractory patients with a median age of 66 years.

Primary endpoints of the study include safety and tolerability. Secondary endpoints include overall response rate, duration of response, complete response, relapse free survival, progression-free survival, and overall survival, as well as pharmacokinetics and immunogenicity. As part of the study protocol, anti-infective prophylaxis, intravenous immunoglobulin (in patients experiencing B-cell loss with an increased risk of infection) and vaccination are strongly recommended.

Further to the previously reported results from LOTIS-7 demonstrating promising clinical activity for the combination of ZYNLONTA plus glofitamab in patients with r/r DLBCL, the Company plans to share full data from LOTIS-7 at a medical meeting and submit the results for publication by the end of 2026. In addition, the Company plans to assess potential regulatory and compendia pathways for the combination.
