ClinConnect Summary

This clinical trial is investigating a new treatment approach for adults with extensive-stage small cell lung cancer (ES-SCLC), which is a type of lung cancer that has spread widely in the body. The researchers want to find out if a combination of a specific chemotherapy treatment, called dose-dense chemotherapy, along with a drug called adebrelimab and a procedure known as hematopoietic stem cell transplantation, can improve survival and the time before the cancer worsens. They will also look at the safety of this treatment throughout the study.

To participate, individuals must be between 18 and 70 years old, have a confirmed diagnosis of ES-SCLC that hasn’t been treated before, and meet certain health criteria. Participants will undergo a series of treatments over several cycles and will have regular check-ups at the clinic every three weeks, along with imaging tests to monitor their progress. This trial is not yet open for enrollment, but it represents a hopeful step towards better options for patients facing this challenging cancer.

Eligibility criteria

  • Inclusion Criteria:
  • 1. Pathologically confirmed small cell lung cancer (SCLC) staged as extensive-stage (ES-SCLC) according to the Veterans Administration Lung Study Group (VALG) classification.
  • 2. ES-SCLC dose not received prior systemic treatment.
  • 3. History of localized-stage SCLC with prior radiotherapy and chemotherapy, with the requirement for definitive treatment, and a minimum of 6 months interval from the last treatment to diagnosis of ES-SCLC.
  • 4. CT or MRI scan ≤28 days prior to the first dose of study medication, with at least one target lesion that has not been irradiated (RECIST v1.1 criteria).
  • 5. Male or female patients aged ≥18 and ≤70 years.
  • 6. ECOG Performance Status of 0 or 1.
  • 7. Life expectancy ≥12 weeks.
  • 8. Adequate organ system function (excluding use of any blood components or growth factors during screening).
  • 9. Male or female participants must agree to use appropriate contraception (e.g., intrauterine device, contraceptive pills, or condoms) from the start of the study treatment until 6 months after the last study treatment; women of childbearing potential must have a negative pregnancy test within 7 days prior to enrollment.
  • 10. Subjects voluntarily participate in this study and sign the informed consent form (ICF).
  • Exclusion Criteria:
  • 1. Histologically or cytologically confirmed mixed SCLC and NSCLC.
  • 2. Prior treatment with any T-cell co-stimulatory or immune checkpoint inhibitors, including but not limited to cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) inhibitors, PD-1 inhibitors, PD-L1/2 inhibitors, or other T-cell targeted agents.
  • 3. Prior treatment with vascular endothelial growth factor (VEGF) or vascular endothelial growth factor receptor (VEGFR) inhibitors.
  • 4. Symptomatic brain metastases, leptomeningeal disease, or spinal cord compression. For treated brain metastases, the following criteria must be met: no progression on MRI ≥4 weeks post-treatment, completion of treatment ≥28 days before the first dose of study drug, and no need for systemic corticosteroids (\>10 mg/day prednisone or equivalent) ≤14 days before the first dose.
  • 5. Hematologic disorders including, but not limited to, lymphoma, acute or chronic leukemia, multiple myeloma, aplastic anemia, or myelodysplastic syndromes.
  • 6. Symptomatic third-space fluid accumulation, such as uncontrolled pericardial effusion, pleural effusion, or ascites despite drainage or other treatments.
  • 7. Active, known, or suspected autoimmune diseases. Exceptions include vitiligo, type 1 diabetes, autoimmune thyroiditis with only hormone replacement therapy, or conditions unlikely to relapse without external stimuli.
  • 8. Use of systemic corticosteroids (\>10 mg/day prednisone or equivalent) or other immunosuppressants ≤14 days before the first dose of study drug. Inhaled or topical corticosteroids and adrenal replacement therapy are allowed if no active autoimmune disease.
  • 9. Receipt of or planned vaccination with live vaccines ≤4 weeks before the first dose of study drug.
  • 10. Interstitial lung disease, drug-induced pneumonitis, radiation pneumonitis requiring corticosteroids, active pneumonia, or severe pulmonary dysfunction.
  • 11. Active tuberculosis or history of active tuberculosis ≤48 weeks before screening, regardless of treatment status.
  • 12. Toxicities from prior anticancer treatment other than alopecia and fatigue must have resolved to CTCAE v4.03 ≤ Grade 1 before the first dose. Long-term sequelae such as platinum-based neurotoxicity are allowed if anticipated to be stable.
  • 13. Imaging (CT or MRI) showing tumor invasion of major vessels, hemoptysis symptoms within 3 months before screening, or daily hemoptysis ≥2.5 mL.
  • 14. Minor surgery (including catheter placement) ≤48 hours before the first dose of study drug.
  • 15. Current or recent use of aspirin (\>325 mg/day) or other nonsteroidal anti-inflammatory drugs known to inhibit platelet function ≤10 days before the first dose.
  • 16. Current or recent use of full-dose oral or parenteral anticoagulants or thrombolytics ≤10 days before the first dose. Preventive anticoagulation is allowed.
  • 17. Known hereditary bleeding disorders or coagulation dysfunction. Significant bleeding symptoms or clear bleeding tendencies (e.g., gastrointestinal bleeding, bleeding ulcers, baseline stool occult blood ++ or more) within 12 weeks before screening.
  • 18. History of thromboembolic events within 24 weeks before signing the ICF, including stroke (including transient ischemic attack, hemorrhagic stroke, or infarction), deep vein thrombosis, or pulmonary embolism.
  • 19. Uncontrolled hypertension (systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg), hypertensive crises, or history of hypertensive encephalopathy.
  • 20. History of gastrointestinal ulcers, perforation, corrosive esophagitis or gastritis, inflammatory bowel disease, diverticulitis, abdominal fistula, tracheoesophageal fistula, or intra-abdominal abscess within 24 weeks before signing the ICF.
  • 21. Uncontrolled cardiac symptoms or diseases, including: (1) NYHA Class ≥II heart failure; (2) unstable angina; (3) myocardial infarction within 24 weeks; (4) clinically significant supraventricular or ventricular arrhythmias requiring treatment or intervention.
  • 22. Known allergy to study drug or excipients, or a history of severe allergic reactions to any monoclonal antibody.
  • 23. Other malignancies within 5 years before the first dose, except for adequately treated cervical carcinoma in situ, basal cell carcinoma, squamous cell carcinoma of the skin, locally excised prostate cancer, or ductal carcinoma in situ with minimal risk of metastasis and expected cure.
  • 24. Known psychiatric disorders, alcohol abuse, drug abuse, or substance misuse.
  • 25. Positive HBsAg with HBV DNA levels exceeding normal limits (1000 copies/ml or 500 IU/ml), or positive HCV (HCV RNA or HCV Ab indicating acute or chronic infection); known HIV positive or acquired immunodeficiency syndrome (AIDS).
  • 26. Uncontrolled or symptomatic hypercalcemia.
  • 27. Receipt of any investigational drug or participation in another interventional clinical trial ≤4 weeks before signing the ICF.
  • 28. History of allogeneic bone marrow transplantation or solid organ transplantation.
  • 29. Use of systemic immunosuppressive drugs ≤2 weeks before randomization.
  • 30. History of hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins, carboplatin, or etoposide.
