Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Phase 1: Dose Exploration

The recommended phase 2 target dose (RP2D) of tarlatamab in combination with AMG 404 will be estimated using a modified toxicity probability interval (mTPI-2) design. A combination RP2D may be identified based on emerging safety, efficacy, and pharmacodynamic data prior to reaching an maximum tolerated dose (MTD).

Group Type EXPERIMENTAL

Tarlatamab

Intervention Type DRUG

Tarlatamab will be administered as an intravenous (IV) infusion.

AMG 404

Intervention Type DRUG

AMG 404 will be administered as an intravenous (IV) infusion.

Phase 2: Dose Expansion

Participants will receive the RP2D of tarlatamab in combination with AMG 404 identified in Phase 1 (dose exploration) of the study.

Group Type EXPERIMENTAL

Tarlatamab

Intervention Type DRUG

Tarlatamab will be administered as an intravenous (IV) infusion.

AMG 404

Intervention Type DRUG

AMG 404 will be administered as an intravenous (IV) infusion.

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participant has provided informed consent/assent prior to initiation of any study specific activities/procedures
* Age greater than or equal to 18 years old at the same time of signing the informed consent
* Participants with histologically or cytologically confirmed Small Cell Lung Cancer (SCLC) who progressed or recurred following at least 1 platinum-based regimen
* Eastern Cooperative Oncology Group (ECOG) 0 to 1
* Participants with treated brain metastases are eligible provided they meet defined criteria
* Adequate organ function as defined in protocol

Exclusion Criteria

* History of other malignancy within the past 2 years with exceptions
* Major surgery within 28 days of first dose of tarlatamab
* Untreated or symptomatic brain metastases and leptomeningeal disease
* Prior anti-cancer therapy, including anti-PD1 or anti-PDL1 antibody therapy: at least 28 days must have elapsed between any prior anti-cancer therapy and the first planned dose of tarlatamab

Exceptions:

* Participants who received prior chemotherapy must have completed at least 14 days before the first dose of tarlatamab and all treatment-related toxicity resolved to grade ≤ 1.
* Participants who received prior palliative radiotherapy must have completed at least 7 days before the first dose of tarlatamab

* Participants who received prior tarlatamab therapy or prior delta-like ligand 3 (DLL3) x cluster of differentiation 3 (CD3) bispecific therapy are not eligible
* Participants who experienced recurrent grade 2 pneumonitis or severe or life-threatening immune-mediated adverse events or infusion-related reactions including those that lead to permanent discontinuation while on treatment with immuno-oncology agents
* History of any immune-related colitis. Infectious colitis is allowed if evidence of adequate treatment and clinical recovery exists and at least 3 months interval observed since diagnosis of colitis
* Participants with evidence of interstitial lung disease or active, non-infectious pneumonitis
* Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of tarlatamab
* History of solid organ transplantation
* History of hypophysitis or pituitary dysfunction
* Active autoimmune disease that has required systemic treatment (except replacement therapy) within the past 2 years or any other diseases requiring immunosuppressive therapy while on study. Participants with Type I diabetes, vitiligo, psoriasis, hypo- or hyper-thyroid disease not requiring immunosuppressive treatment are permitted
