Eligibility
Key inclusion criteria
* Participants = 18 years of age (or = legal adult age within country if it is older than 18 years) at time of signing informed consent.
* Participants with histologically or cytologically confirmed ES-SCLC that progressed or recurred following at least one line of platinum-based anti-cancer therapy for SCLC.

Note: Participants with prior treatment for LS-SCLC should have also received another regimen for their recurrent, ES-SCLC disease.

* Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or 1.
* Participants must have adequate organ function (cardiac, pulmonary, kidney, and liver).
* Participants must be able to have SC injections administered in the abdomen (and/or thigh).
* Participants without measurable disease or tumor tissue (fresh biopsy or archival) available may be permitted after discussion with and approval by Amgen Medical Monitor.
Minimum age
18 Years
Maximum age
No limit
Sex

Can healthy volunteers participate?
No
Key exclusion criteria
* Participants that have received prior DLL3 targeted therapy.
* Participants with untreated or symptomatic brain metastases or those requiring therapy with steroids.
* Note: Participants with asymptomatic brain metastatic lesions are allowed following definitive treatment (Amgen Medical Monitor may approve untreated, asymptomatic brain metastasis if local therapy is not required per investigator judgment).
* Participants with leptomeningeal disease.
* Participants with baseline oxygen requirement.
