A Study to Evaluate Adverse Events and Change in Disease Activity of Intravenous ABBV-706 Versus Standard of Care in Adult Participants With Relapsed/Refractory Small Cell Lung Cancer
What this study is about
Small cell lung cancer (SCLC) is characterized by aggressive and rapid growth and a tendency to develop early spread to distant sites including mediastinal lymph nodes, liver, bones, adrenal glands, and brain.
View original scientific description
Small cell lung cancer (SCLC) is characterized by aggressive and rapid growth and a tendency to develop early spread to distant sites including mediastinal lymph nodes, liver, bones, adrenal glands, and brain. The purpose of this study is to assess safety, tolerability, and change in disease activity of ABBV-706 compared to standard of care (SOC) treatment (topotecan, lurbinectedin, or amrubicin). ABBV-706 is an investigational drug being developed for the treatment of SCLC. There are two treatment arms in this study. Participants will either receive ABBV-706 or SOC. Approximately 531 adult participants will be enrolled in the study across 175 sites worldwide. Participants with SCLC will receive intravenous (IV) ABBV-706 or SOC \[topotecan (IV or orally), or lubinectedin (IV), or amrubicin (IV)\]. The estimated duration of the study is approximately 53 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, questionnaires, and scans.

Primary outcome measures
Objective Response (OR) as Measured by Overall Response Rate (ORR) Based on Blinded Independent Central Review (BICR)
Time frame: Up to approximately 24 months
OR is defined as participants achieving a best overall response (BOR) of confirmed complete response (CR)/partial response (PR) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 as determined by BICR assessment prior to initiation of subsequent anti-cancer therapy. OR will be summarized by ORR, defined as the percentage of participants achieving OR and will be summarized for each arm with its associated 95% confidence interval (CI).
Overall Survival (OS)
Time frame: Up to approximately 28 months
OS is defined as the time from the date of randomization to the date of death of any cause.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
