Adebrelimab and Concurrent Radiochemotherapy as First-line Treatment for Extensive-stage Small-cell Lung Cancer

January 24, 2024 updated by: Henan Cancer Hospital

Patients with extensive-stage small-cell lung cancer (ES-SCLC) have poor prognosis, with limited treatment options. Chemo-immunotherapy is the standard 1st-line therapy for patients with ES-SCLC.When 4 cycles of etoposide+carboplatin (EC) or etoposide+cisplatin(EP) chemotherapy combined with PD-L1 inhibitor are effective, guidelines recommend additional thoracic radiotherapy.

In this study, the investigators bring radiotherapy forward, which means that after 2 cycles of EC chemotherapy plus Adebrelimab, participants with response（PR/CR/SD）will receive concurrent radiotherapy and 2 cycles of EC chemotherapy plus Adebrelimab, then maintenance therapy with Adebrelimab （Q3W）.

The purpose of this study is to explore the safety and efficacy of Adebrelimab combined with concurrent chemoradiotherapy in untreated participants with extensive-stage small cell lung cancer.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants receive EC chemotherapy combined with Adebrelimab for 2 cycles, and the efficacy will be evaluated. If the efficacy evaluation is SD/PR/CR, concurrent chemoradiotherapy combined with EC(2 cycles) + Adebrelimab will be initiated. After concurrent chemoradiotherapy + Adebrelimab, Adebrelimab was maintained until PD or intolerance or for at most 2 years.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Aged 18-75 years;

  3. Must sign a written informed consent form prior to any study specific procedures;
  4. No prior treatment for ES-SCLC;
  5. No more than 5 lesions (including metastases),and at least one measurable lesion that meets RECIST 1.1 evaluation criteria;

Exclusion Criteria:

  1. Previous treatment with radiochemotherapy for limited-stage small cell lung cancer;
  2. Subjects who previously received systemic antitumor or Immune checkpoint inhibitor therapy ;
  3. Active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs); replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment;
  4. Active brain metastases, Leptomeningeal metastasis(untreated central nervous system (CNS) metastases unless asymptomatic and lesion size<1cm;
  5. Patients with spinal cord compression;
  6. Patients with multiple liver metastases(except isolated lesion and lesion size<2cm);
  7. Uncontrollable third cavity effusion (e.g. a large amount of pleural effusion, ascites, or pericardial effusion, etc.) requiring repeated drainage, which was judged by the investigator to be unsuitable for study;
  8. The investigator judges that there are any patients who endanger the patient's safety, interfere with the study assessment, and have poor compliance.
