New hope for tough lung cancer: ABBV-706 faces off against standard care
NCT ID NCT07365241
First seen Jun 27, 2026 · Last updated Sep 09, 2026 · Updated 16 times
Summary
This study tests a new drug, ABBV-706, against standard treatments for small cell lung cancer that has come back or stopped responding. About 531 adults will receive either ABBV-706 or usual care (topotecan, lurbinectedin, or amrubicin) to see which works better. The goal is to shrink tumors and help people live longer.

Inclusion Criteria: * Diagnosis of histologically or cytologically confirmed Relapsed/Refractory (R/R) Small Cell Lung Cancer (SCLC). * Participants must have progressed on prior systemic therapy, with CPI (if eligible) and prior tarlatamab, defined as: * In the 1L and 2L setting respectively, platinum-based chemotherapy (i.e., carboplatin or cisplatin and etoposide with CPI, if eligible for CPI) and 2L tarlatamab; or * In the 1L and 2L setting, platinum-based chemotherapy (i.e., carboplatin and etoposide with atezolizumab and lurbinectedin in combination with atezolizumab maintenance and 2L tarlatamab; or * In the 1L setting, platinum-based chemotherapy (i.e., carboplatin or cisplatin and etoposide with CPI if eligible) in combination with tarlatamab in frontline induction and/or maintenance * Participants must be considered suitable to receive SOC comparator (topotecan, lurbinectedin, or amrubicin). * Participants must have an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 1 during the screening period prior to the first dose of study treatment. * Participants must have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Target lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions. * Participants with brain metastasis from an extracranial solid tumor are eligible if the brain metastases are: * Previously treated and not requiring anticonvulsants and steroids for at least 7 days prior to first dose of study treatment. If required for management, subjects on a steroid equivalent of prednisone dose of ≤ 10 mg/day are eligible or; * Untreated and asymptomatic not requiring anticonvulsants and steroids for at least 7 days prior to the first dose of study treatment. If required for management, subjects on a steroid equivalent of prednisone of ≤ 10 mg/day are eligible. Exclusion Criteria: * Participants with known active/symptomatic central nervous system metastases. * Participants with a history of interstitial lung disease (ILD) or pneumonitis that previously required treatment with systemic steroids, or any evidence of active ILD/pneumonitis on screening chest computed tomography (CT) scan. * Participants with any clinically significant conditions that would adversely affect the participation in the study, and the subject should have a life expectancy of at least 3 months. * Participants who have received prior treatment with a seizure-related 6 homolog (SEZ6) targeted Antibody drug conjugate (ADC), other targeted ADCs, or any other investigational agent not including tarlatamab in 1L. * Participants who have received prior treatment with any Top1i such as topotecan, irinotecan, belotecan, camptothecin, rubitecan, exatecan or locally approved topoisomerase I inhibitor (Top1i) payload.
