Key Financial and Operating Metrics

- The principal operating update is the dosing of the first patient in China in a pivotal Phase 2 trial of ZYNLONTA (loncastuximab tesirine-lpyl) for relapsed or refractory diffuse large B-cell lymphoma.
- The China study is a multicenter, open-label, single-arm trial evaluating ZYNLONTA as a monotherapy and is intended to support potential registration in China.
Material Changes Versus the Prior Comparable Period
- No comparable-period financial information is presented.
- The reported development milestone is the initiation of patient dosing in the China Phase 2 trial, which mirrors ADC Therapeutics’ ongoing global pivotal Phase 2 trial.
