Programmed Cell Death-1 (PD1, PD-1), Programmed Cell Death 1 Ligand 1(PDL1, PD-L1), Programmed Cell Death 1 Ligand 2 (PDL2, PD-L2)

Brief summary

The main goals are after treatment given before surgery, to measure the number of people who have no signs of cancer cells in tumors and lymph nodes removed during surgery; and to learn about whether the cancer gets smaller or goes away by measuring the number of people with a certain number of living cancer cells in the tumor removed during surgery.

Exclusion criteria

include but are not limited to the following: Inclusion Criteria: * Has previously untreated and pathologically confirmed resectable Stage II, IIIA, or IIIB (N2) non-small cell lung cancer (NSCLC) * Able to undergo protocol therapy, including necessary surgery * Confirmation that epidermal growth factor receptor (EGFR) -directed therapy is not indicated as primary therapy * Has an Eastern Cooperative Oncology Group (ECOG) performance status of either 0 or 1 as assessed within 10 days before initiation of study intervention. * Is able to provide archival or newly obtained core/excisional biopsy of the primary lung tumor or lymph node metastasis.

Design outcomes

Primary

MeasureTime frameDescription
Pathological Complete Response (pCR)Up to approximately 20 weekspCR is defined as absence of residual viable invasive cancer on hematoxylin- and eosin-stained slides of the resected lung specimen and lymph nodes.
Percent Residual Viable Tumor (%RVT)Up to approximately 20 weeks%RVT is defined as the percentage of residual tumor estimated by comparing the estimated cross-sectional area of viable tumor with estimated cross-sectional areas of remainder of tumor bed. The tumor bed is defined as the area of tissue occupied by viable tumor or tumoral regression (includes areas of necrosis, foamy macrophages, giant cell reaction, cholesterol cleft granuloma, and inflammation.)

Secondary

MeasureTime frameDescription
Percentage of Participants Who Report at Least 1 Adverse Event (AE)Up to approximately 5 yearsAn AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
Percentage of Participants Who Discontinue Study Treatment Due to an AEUp to approximately 1 yearAn AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
Event-free Survival (EFS)Up to approximately 5 yearsEFS is defined as the time from randomization to any of the following events: radiographic disease progression per Response Evaluation Criteria In Solid Tumors 1.1 (RECIST 1.1) (for participants who have not had or will not have surgery, or participants who have gross residual disease after an incomplete resection \[R2 resection\]); local progression (primary tumor or regional lymph nodes) or distant metastasis precluding planned surgery; tumor determined to be unresectable in the operating room; local or distant recurrence (for participants who are disease free after surgery or participants with microscopic positive margins \[R1 resection\]); occurrence of new primary NCSLC; death due to any cause.
Overall Survival (OS)Up to approximately 5 yearsOS is defined as the time from randomization to death due to any cause.
Distant Metastasis-Free Survival (DMFS)Up to approximately 5 yearsDMFS is defined as the time from randomization to the date of diagnosis of distant metastasis or death, whichever occurs first.
Objective Response Rate (ORR)Up to approximately 12 weeksOR is defined as a complete response or partial response with or without confirmation per RECIST 1.1 as assessed by the investigator during the Neoadjuvant Phase.
Percentage of Participants Who Experience a Perioperative ComplicationUp to approximately 20 weeksPerioperative Complications include both intraoperative and postoperative complications.
Mean Length of Hospital StayUp to approximately 20 weeksHospital Stay is the length of inpatient time spent in hospital.
Percentage of Participants Who Require Hospital Readmission after DischargeUp to approximately 20 weeksIn participants previously discharged from hospital, the percentage requiring readmission to hospital.
Mean Length of SurgeryUp to approximately 20 weeksLength of surgery is the time spent in surgery.
Percentage of Participants Who Require a Blood TransfusionUp to approximately 20 weeksBlood transfusion is the transfer of donated blood into the vein of a recipient.
