简要总结
This is a trial in adult participants with unresectable, locally advanced, Stage III non-small cell lung cancer (NSCLC) treated with pembrolizumab in combination with platinum doublet chemotherapy and standard thoracic radiotherapy followed by pembrolizumab monotherapy. The primary hypothesis of the trial is that within each platinum doublet chemotherapy cohort, the percentage of participants who develop Grade 3 or higher pneumonitis is ≤10% and estimation of objective response rate (ORR) by blinded independent central review (BICR).

时间窗: Up to approximately 3 years
ORR was defined as the percentage of participants who experienced a complete response (CR; disappearance of all target lesions) or a partial response (PR; at least a 30% decrease in the sum of diameters of target lesions) and was assessed using modified RECIST 1.1 by blinded independent central review (BICR).
Percentage of Participants Who Developed Grade 3 or Higher Pneumonitis
时间窗: Up to approximately 3 years
Pneumonitis included the MedDRA preferred terms for radiation pneumonitis are acute interstitial pneumonitis, autoimmune lung disease, interstitial lung disease, pneumonitis, idiopathic pneumonia syndrome, organizing pneumonia, and immune-mediated pneumonitis. As per common terminology criteria for Adverse Events, version 4.0, pneumonitis was graded as follows: Grade (Gr) 1- asymptomatic, clinical or diagnostic observations only; intervention not indicated; Gr 2- symptomatic, medical intervention indicated, limiting instrumental activities of daily living (ADL); Gr 3- severe symptoms; limiting self-care activities of daily living (ADL), oxygen indicated; Gr 4- life-threatening respiratory compromise; urgent intervention indicated (e.g., tracheotomy or intubation); Gr 5- death.
