New drug duo takes on tough lung cancer
NCT ID NCT07037758
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial is testing whether combining two drugs, tarlatamab and AB248, is safe and tolerable for people with extensive stage small cell lung cancer that has worsened after at least one prior treatment. About 380 adults will take part. The main goals are to check for side effects and find the best dose of the combination.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tarlatamab and AB248 (two drugs given by IV infusion)
- What this could lead to
- If it works, this could point toward a new combination treatment for extensive stage small cell lung cancer that has stopped responding to other therapies.
- What could go wrong
- This is a very early Phase 1b study, so safety and the right dose are still being figured out. Many drug combinations fail at this stage, and side effects could be serious.

Inclusion Criteria: 1. Participant has provided informed consent before initiation of any study-specific activities/procedures. 2. Participants ≥ 18 years (or ≥ legal age within the country if it is older than 18 years) at the time of signing the informed consent. 3. Participants with histologically or cytologically confirmed ES-SCLC that has progressed or recurred following at least 1 line of anti-cancer therapy for ES-SCLC. 4. Participants must have at least 1 measurable lesion as defined by RECIST 1.1 within 21-day screening period, not previously irradiated. 5. Participants must have adequate organ function (hematological, coagulation, cardiac, pulmonary, kidney, and liver). 6. Participants must submit a fresh tumor biopsy at screening unless a new biopsy cannot be performed safely or is infeasible. Participants who cannot provide fresh tissue may provide archival tissue that was collected after last anticancer therapy. Exclusion Criteria: 1. Symptomatic central nervous system (CNS) metastases. 2. Participants with brain metastases may be eligible if criteria defined in the protocol are met. 3. Prior therapy with any delta-like ligand 3 (DLL3)-directed therapy (including tarlatamab). 4. Prior interleukin (IL)-2, IL-7 or IL-15 targeted therapy. 5. Baseline (at rest) requirement of supplemental oxygen.
