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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Change from baseline at Week 12 in physical functioning as measured by the physical functioning domain of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30).
Health-related quality-of-life (HRQoL) and symptoms will be assessed with the EORTC QLQ-C30, version 3.0. The EORTC QLQ-C30 is a 30-item patient-reported questionnaire composed of both multi-item and single scales including 5 functional scales (physical, role, emotional, social, and cognitive), 3 symptom scales (fatigue, nausea and vomiting, and pain), a global health status (GHS)/QoL scale, and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). Participants rate items on a 4 point scale ranging from 1 to 4 (1 = Not at All, 2 = A Little, 3 = Quite a Bit, and 4 = Very Much).

Started Jul 2026 (actual). Primary completion is estimated for Sep 2030, 50 months after the start.
Of 55 industry-sponsored phase 3 interventional studies under Small Cell Lung Carcinoma, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 30 and three quarters within 44. This study's planned 50 months is above that.
Counting every sponsor, half of 68 studies reached it within 41 months; a quarter within 31 and three quarters within 48.
