About this trial

An open-label, multicenter study of ZL-1310 as a single agent and in combination with Atezolizumab (with and without Carboplatin) to evaluate the safety, efficacy, and pharmacokinetics in subjects with small cell lung cancer

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Signed informed consent

Participant with metastatic or extensive-stage small cell lung cancer (de novo, not transformed) and for Part 1A and 1B must have documented disease progression during or following a platinum-based chemotherapy regimen. For Part 1C and Part 4, no prior systemic treatment for SCLC (including chemoradiotherapy for limited-stage SCLC). For Part 1B backfill and Part 3, first-line setting: no prior systemic treatment for SCLC (including chemoradiotherapy for limited-stage SCLC); or, first-line maintenance setting: participants have received at least 4 cycles of 1L induction therapy with carboplatin or cisplatin, etoposide, and anti-PD-L1 inhibitor for ES-SCLC with ongoing CR, PR, or SD per RECIST v1.1 assessed by the investigator. For Part 2-1, participants must have received no more than 2 lines of prior therapies in the extensive-stage setting, and progressed on or after a platinum-based chemotherapy regimen AND an anti-DLL3 T-cell engager (TCE). For Part 3, participants have received at least 4 cycles of 1L induction therapy with carboplatin or cisplatin etoposide, and anti-PD-L1 inhibitor for ES-SCLC with ongoing CR, PR, or SD per RECIST v1.1 assessed by the investigator.

Adult men and women ≥18 years of age.

Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

Disqualifiers

Participants with another known malignancy that is progressing or requires active treatment within the last 2 years. Exceptions: basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin with previously administered curative treatment, in situ cervical cancer, or other cancers that do not require systemic anti-cancer therapies and will not impact life expectancy.

Subjects with untreated and asymptomatic brain metastases.

Subjects with treated brain metastases that are no longer symptomatic (i.e. without neurologic signs or symptoms), who require no treatment with steriods or anticonvulsants and have recovered from the actue toxic effects of radiotherapy.

Subjects with leptomeningeal disease.
