New combo therapy targets tough lung cancer
NCT ID NCT06898957
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tests a combination of three drugs—tarlatamab, YL201, and durvalumab—in 29 adults with extensive stage small cell lung cancer that has progressed after prior treatment. The main goal is to check safety and side effects, while also measuring how well the tumors respond. It's a small, early study, so results will guide future research rather than offer a new treatment right away.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tarlatamab, YL201, and Durvalumab (anti-PD-L1)
- What this could lead to
- If successful, this could point toward a new combination treatment option for people with advanced small cell lung cancer.
- What could go wrong
- This is a very early, small phase 1b study focused on safety, not proof of effectiveness. The combination may cause serious side effects or fail to shrink tumors.

Inclusion Criteria: * Participants ≥ 18 years of age (or legal adult age within country) at time of signing informed consent. * Participants with histologically or cytologically confirmed ES-SCLC. * For Parts 1 and 2, subjects must have ES-SCLC that has progressed or recurred following at least 1 prior line of platinum-based anti-cancer therapy received either for LS-SCLC or ES-SCLC. * For Part 3, subjects must have ES-SCLC and no prior systemic treatment for ES SCLC other than 1 cycle of platinum-based chemotherapy, and etoposide, and with or without PD-(L)1 inhibitor in the first-line setting. * At least 1 measurable lesion as defined by RECIST 1.1. * Participants must have adequate organ function (cardiac, pulmonary, kidney, bone marrow, and liver). Exclusion Criteria: * Prior delta-like ligand 3 (DLL3) or B7 homolog 3 (B7-H3) targeted therapy. * Prior exposure to topoisomerase I inhibitors or antibody-drug conjugate (ADC) with topoisomerase I inhibitor payload. * Symptomatic central nervous system (CNS) metastases. Note: Participants with asymptomatic brain metastases are eligible as defined in the protocol. * History of (non-infectious) interstitial lung disease (ILD)/pneumonitis that required corticosteroids, current ILD/pneumonitis, or suspected ILD/pneumonitis that cannot be ruled out by imaging at screening. * Baseline requirement of supplemental oxygen.
