入选标准
- •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
- •Participants must have adequate organ function (cardiac, pulmonary, kidney, and liver).
- •Participants must be able to have SC injections administered in the abdomen.
- •Participants without measurable disease or tumor tissue (fresh biopsy or archival) available may be permitted after discussion with and approval by Amgen Medical Monitor.
排除标准
- •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.
研究组 & 干预措施
Part 3 Alternative Dosing
Following the selection of a SC dosing regimen from Part 1 that will be used in Part 2 dose expansion, Part 3 may open to test alternative dosing of SC tarlatamab.

Part 2 Dose Expansion
Following the selection of a SC dosing regimen in Part 1, tarlatamab will be administered in Part 2 at the dose deemed safe and tolerable in Part 1.
干预措施: Tarlatamab (Drug)
Part 1 Dose Exploration
Tarlatamab will be administered as a SC injection in Part 1.
干预措施: Tarlatamab (Drug)
