Brief Summary

This study aimed to evaluate the efficacy and safety of bronchoscopic cryoablation combined with sintilimab plus platinum-based chemotherapy as First-line Treatment for locally advanced or metastatic NSCLC with central airway obstruction.

Detailed Description

This is a prospective interventional clinical study to evaluate the efficacy and safety of bronchoscopic cryoablation combined with sintilimab plus platinum-based chemotherapy as First-line Treatment for locally advanced or metastatic Non-small Cell Lung Cancer with central airway obstruction.

Approximately 39 patients with locally advanced or metastatic NSCLC and central airway obstruction, without EGFR-sensitive mutations (19del, L858R, and T790M), were enrolled and treated with bronchoscopic cryoablation combined with Sintilimab, Nab-Paclitaxel, and Carboplatin until disease progression, intolerable toxicity, or meeting the criteria for discontinuation of the trial drug.

The primary endpoint is the investigator-assessed objective response rate (ORR) of airway tumors. Secondary endpoints include the pathological response rate (PRR) of airway tumors, disease control rate (DCR), improvement rate of FEV1, duration of response (DOR) for airway tumors, progression-free survival (PFS), overall survival (OS), quality of life assessment, and safety. Recruitment for the study is expected to begin in mainland China around October 2024, with the trial anticipated to conclude in October 2027.

Inclusion Criteria
  • Understand the requirements and contents of the clinical trial and provide a signed and dated informed consent form.
  • Age≥18 years and≤80 years.
  • Histologically or cytologically confirmed and documented locally advanced or metastatic non-small cell lung cancer (NSCLC) without prior systemic therapy and EGFR-sensitive mutations (19del, L858R and T790M).
  • Presence of a palliative treatment lesion in the central airway that is amenable to ablation, endoscopically assessed to be≥1/3 obstruction, such as primary or metastatic malignancy to the trachea, main bronchi, intermediate bronchi, or segmental bronchi. corresponding respiratory symptoms or obstructive pneumonia is permission to be included.
  • Eastern Cooperative Oncology Group (ECOG) : 0-2.
  • Predicted survival ≥ 12 weeks.
  • Adequate bone marrow hematopoiesis and organ function (cardiac function, hepatic, and renal function).
  • Presence of measurable lesions according to RECIST 1.1 criteria.
  • Subjects with stable brain metastases may be included in the study.
Exclusion Criteria
  • Histological diagnosis of small cell, large cell lung cancer; mixed tumors will be classified based on the primary cell type; if the primary component is small cell, large cell, or neuroendocrine carcinoma, the subject will not be eligible for enrollment; however, mixed adenocarcinoma-squamous cell carcinoma is acceptable. Subjects with driver gene mutations are generally not eligible for enrollment.
  • Malignant central airway obstruction with acute dyspnea or severe life-threatening symptoms of malignant airway stenosis, or assessed by the investigator to be unable to tolerate subsequent treatment; extrinsic airway compression; large pleural effusion, severe coughing, massive hemoptysis, dyspnea, or inability to cooperate; severely impaired lung function with a maximal voluntary ventilation (MVV) < 39% or inability to ambulate.
  • Prior systemic therapy for locally or metastatic disease.
  • Uncorrectable coagulation disorders, severe bleeding tendencies, platelet count < 50 *10^9/L, or severe coagulation dysfunction.
  • Presence of symptomatic brain metastases.
  • Known severe hypersensitivity to anti-PD-1 monoclonal antibodies or similar drugs (allergic reactions with CTCAE≥ grade 3 toxicity).
  • Subjects with persistent or active infection, including but not limited to hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV).
  • Any concurrent malignancy other than basal cell carcinoma or cervical carcinoma in situ. (Patients with a history of malignant tumors but with no evidence of disease for≥ 3 years may be included ).
  • Women who are breastfeeding or pregnant.
  • Other conditions assessed by the investigator to be unsuitable for participation in the study.

Primary Outcome Measures
NameTimeMethod
Objective Response Rate of Airway TumorTime from first dose to last dose, or up to 24 month

The ORR for Objective response of airway tumors after cryoablation combined with immunochemotherapy was evaluated according to the investigator's Solid Tumor Response Assessment Criteria (RECIST) version 1.1, defined as the proportion of subjects who were evaluated for complete response (CR) + partial response (PR) to airway tumors after the first documented treatment

Secondary Outcome Measures
NameTimeMethod
Pathological Response Rate of Airway ObstructionTime from first dose to last dose, or up to 24 month

The pathologic response rate of airway tumors obstruction in patients treated with cryoablation combined with immunochemotherapy was evaluated according to the investigator which was defined as the proportion of subjects with endoscopically assessed airway pathologic residual tumors ≤10% after treatment recorded for the first or last time after cryoablation

Airway Obstruction Response Control RateTime from first subject dose to study completion, or up to 36 month

The DCR for airway tumors obstruction in patients treated with cryoablation combined with immunochemotherapy was assessed according to the investigator's RECIST 1.1, defined as the proportion of subjects evaluated for complete (CR) + partial response (PR) and stable SD for intraairway tumors after the first recorded treatment

FEV1R improvement rate of airway obstructionTime from first subject dose to study completion, or up to 36 month

Calculated according to the subjects' pulmonary function measures assessed by the investigator: FEV1 (post-treatment) -FEV1 (pre-treatment)/FEV1 (pre-treatment) \*100%

Airway Obstruction Response DurationTime from first subject dose to study completion, or up to 36 month

The duration of response in subjects with CR or PR was assessed according to the Solid Tumor Response Assessment Criteria (RECIST) version 1.1 developed by the investigators, defined as the time from the first recorded evaluated airway tumor CR or PR to airway disease progression or death

Progression-free survivalTime from first subject dose to study completion, or up to 36 month

Progression-free survival of patients treated with cryoablation plus immunochemotherapy was assessed according to the Investigator Response Evaluation criteria (RECIST) version 1.1, defined as the duration of first documented disease progression or death from any cause

Overall survivalTime from first subject dose to study completion, or up to 36 month

To assess overall survival, it was defined as the first dose at which the subject died from any cause

Adverse eventsTime from first subject dose to study completion, or up to 36 month

Number of participants with adverse events (AEs) according to CTCAE 5.0

Life quality scoreTime from first subject dose to study completion, or up to 36 month
