ADC Therapeutics SA (NYSE: ADCT) shares fell soon after the open Wednesday. The company, a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs), today announced positive initial data from the LOTIS-7 Phase 1b open-label clinical trial evaluating the safety and efficacy of ZYNLONTA® in combination with the bispecific antibody glofitamab (COLUMVI™) in patients with relapsed or refractory diffuse large B-cell lymphoma (r/r DLBCL).
"We are excited by the strong initial results observed with ZYNLONTA plus glofitamab in second line plus patients with relapsed or refractory DLBCL," said Mohamed Zaki, Chief Medical Officer of ADC Therapeutics. "We believe these data support our hypothesis that combining these two potent, approved, single-agent-drugs with complementary mechanisms of action will yield additive or synergistic efficacy, and a manageable safety profile given no overlapping non-hematologic toxicities, enabling administration across care settings. We are encouraged by the initial promising safety and efficacy data at both doses tested in the expansion arm."
LOTIS-7 is an ongoing Phase 1b global multicenter, multi-arm study in patients with relapsed or refractory (r/r) B-cell non-Hodgkin lymphoma (B-NHL) including Part 1 (dose escalation) and Part 2 (dose expansion). As of the November 20 cutoff date, a total of 29 B-NHL patients from Part 1 and Part 2 across all dose levels were treated and evaluated for safety.
ADCT shares lost 33 cents, or 9.5%, to $3.15.
