About this trial

The goal of this clinical trial is to learn if hematopoietic stem cell transplantation-supported dose-dense chemotherepy with adebrelimb works to treat extensive-stage small-cell lung cancer in adults. It will also assess the safety of this treatment approach.

The main questions it aims to answer are:

Does hematopoietic stem cell transplantation-supported dose-dense chemotherepy with adebrelimb improve the median progression free survival and 12-months overall survival rates? What medical problems do participants experience whild undergoing this treatment?

Participants will:

Complete two 21-days cycles of standard-dose etoposide and carboplatin, followed by G-CSF for stem cell mobilization.

Receive dose-dense chemotherapy followed by autologous stem cell reinfusion for two 21-day cycles.

If eligible, participants will receive etoposide and carboplatin plus adebrelimab for four cycles.

Finally, participants may enter a maintenance phase with adebrelimab.

Throughout the trial, participants will:

Visit the clinic every 21 days for check-ups and tests. Imaging examination every 6 weeks. Followed up by telephone every 2 months

Eligibility criteria

Qualifiers

Pathologically confirmed small cell lung cancer (SCLC) staged as extensive-stage (ES-SCLC) according to the Veterans Administration Lung Study Group (VALG) classification.

ES-SCLC dose not received prior systemic treatment.

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.

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).

Disqualifiers

Histologically or cytologically confirmed mixed SCLC and NSCLC.

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.

Prior treatment with vascular endothelial growth factor (VEGF) or vascular endothelial growth factor receptor (VEGFR) inhibitors.

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.
