DLL3-Targeted ADC Produces Responses in Previously Treated ES-SCLC (Cancer Network) - "'The preliminary results from the ongoing phase 1 trial of ZL-1310 suggest that this next-generation ADC therapy has the potential to deliver anti-tumor responses in the majority of patients with ES-SCLC, with good tolerability,' Alexander Spira MD, PhD...stated in the press release. 'This is particularly encouraging given the urgent need for improved treatment options for these patients. These promising data support continued evaluation of ZL-1310 as a monotherapy in the dose-expansion phase of the ongoing phase 1 clinical trial and in combination.'"

ZL-1310, an Investigational DLL3-Targeted Antibody-Drug Conjugate (ADC), Demonstrates Promising Objective Response Rates and Safety Profile in Extensive-Stage Small Cell Lung Cancer (Businesswire) - P1 | N=112 | NCT06179069 | Sponsor: Zai Lab (Shanghai) Co., Ltd | "Data shared in the ENA presentation from the ongoing Part 1a monotherapy dose-escalation portion of the study included results from 25 patients across four dose cohorts (0.8 mg/kg, 1.6mg/kg, 2.0 mg/kg, and 2.4 mg/kg). Nineteen patients had evaluable tumor assessments...The ORR in patients with at least one post-treatment evaluation was 74% (95%CI, 48.8, 90.9). ZL-1310 anti-tumor activity was demonstrated across all dose levels; Responses were seen in patients with DLL3 H-scores from 5 (range: 5 to 260). No response was observed in a patient whose tumor did not express DLL3; ZL-1310 was well tolerated across all dose levels with the majority of treatment emergent adverse events (TEAE) being Grade 1 or 2."
