ZYNLONTA™ LOTIS-2 updated data includes median duration of response of 13.4 months in heavily pre-treated patients with relapsed or refractory DLBCL
Subgroup analyses include patients with double- / triple-hit, advanced stage or transformed DLBCL, DLBCL refractory to first-line therapy, and patients older than 65
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, today announced updated clinical data from the ZYNLONTA™ (loncastuximab tesirine-lpyl) Phase 2 LOTIS-2 trial in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) were presented at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting, which is being held virtually June 4-8, 2021.
“The maturing duration of response from the ZYNLONTA Phase 2 trial reported at ASCO reflects the strong data set that served as the basis of the accelerated FDA approval in April,” said Jay Feingold, MD, PhD, Senior Vice President and Chief Medical Officer of ADC Therapeutics. “We are especially encouraged to see this positive trend continue to strengthen in a heavily pre-treated patient population, including patients with double- / triple-hit, advanced stage or transformed DLBCL, DLBCL refractory to first-line therapy, and patients older than 65.”
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, including analysis of response in high-risk subgroups, were presented in a poster (abstract number: 7546) by Paolo F. Caimi, MD, University Hospitals Cleveland Medical Center and Case Comprehensive Cancer Center, Case Western Reserve University.
