Study of Efficacy and Safety of Ociperlimab in Combination With Tislelizumab and Platinum-based Doublet Chemotherapy as First-line Treatment for Participants With Locally Advanced or Metastatic NSCLC.

Study Overview
=================
Brief Summary
-----------------
The primary scientific question of interest is whether the addition of ociperlimab to platinum-based chemotherapy and tislelizumab improve progression-free survival (PFS) or overall survival (OS) compared to pembrolizumab and platinum-based chemotherapy as first-line therapy for participants with locally advanced or metastatic squamous or non-squamous NSCLC with PD-L1 expression of ≥1%.

Detailed Description
-----------------
This is a randomized, double-blind, placebo controlled, multicenter, phase III study evaluating the efficacy and safety of ociperlimab in combination with tislelizumab and platinum-based doublet chemotherapy as first-line treatment for participants with locally advanced or metastatic NSCLC without actionable driver mutations. Participants will receive study treatment every three weeks and will continue to receive it until RECIST 1.1 disease progression as determined by Investigator and confirmed by BIRC, unacceptable toxicity that precludes further treatment, treatment is discontinued at the discretion of the Investigator or participant, participant withdrawal of consent, pregnancy, lost to follow-up, or death.

| Time to definitive 10-point deterioration in physical and role functioning on the EORTC QLQ-C30 questionnaire | The EORTC QLQ-C30 is a questionnaire developed to assess the health-related quality of life of cancer participants.

All of the domain scores range from 0 to 100. A high score for a functional scale indicates a high and healthy level of functioning but a high score for a symptom scale indicates a high level of symptoms. The time to definitive 10 point deterioration of physical functioning and role functioning is defined as the time from the date of randomization to first onset of ≥10 points increase from baseline (worsening) of the corresponding scale score, with no later change below this threshold or death due to any cause. | Up to 30 months |

The lung cancer module incorporates one multi-item scale to assess dyspnea, and 9 single items assessing pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. All of the domain scores range from 0 to 100. A high score indicates a high level of symptoms. The time to first 10 point deterioration symptom scores of chest pain, cough and dyspnea is defined as the time from the date of randomization to first onset of ≥10 points increase from baseline (worsening) of the corresponding scale score, with no later change below this threshold or death due to any cause. | Up to 30 months | 
| Time to confirmed 10-point deterioration in physical and role functioning on the EORTC QLQ-C30 questionnaire | The EORTC QLQ-C30 is a questionnaire developed to assess the health-related quality of life of cancer participants.

All of the domain scores range from 0 to 100. A high score for a functional scale indicates a high and healthy level of functioning but a high score for a symptom scale indicates a high level of symptoms. The time to confirmed 10-point deterioration of physical functioning and role functioning is defined as the time from the date of randomization to first onset of≥10 points deterioration from baseline and confirmed by a second consecutive ≥10 points deterioration from baseline, or one assessment followed by death from any cause before the next scheduled data collection. | Up to 30 months |

The time to first 10 point deterioration symptom scores of chest pain, cough and dyspnea is defined as the time from the date of randomization to first onset of≥10 points deterioration from baseline and confirmed by a second consecutive ≥10 points deterioration from baseline, or one assessment followed by death from any cause before the next scheduled data collection. | Up to 30 months | 
| Time to definitive 10-point deterioration in global health status/quality of life, shortness of breath and pain on the EORTC QLQ-C30 questionnaire | The EORTC QLQ-C30 is a questionnaire developed to assess the health-related quality of life of cancer participants. It assesses 15 domains consisting of 5 functional domains (physical, role, emotional, cognitive, social) and 9 symptom domains (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties) and a global health status/quality of life (QoL) scale. All of the domain scores range from 0 to 100. A high score for a functional scale indicates a high and healthy level of functioning but a high score for a symptom scale indicates a high level of symptoms. The time to definitive 10-point deterioration in global health status/quality of life, shortness of breath and pain scores is defined as the time from the date of randomization to first onset of ≥10 points increase from baseline (worsening) of the corresponding scale score, with no later change below this threshold or death due to any cause. | Up to 30 months | 
| Utility scores of the EQ-5D-5L | EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life and translates that score into an index value or utility score. EQ-5D-5L consists of two components: a health state profile and an optional visual analogue scale (VAS). EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: 1= no problems, 2= slight problems, 3= moderate problems, 4= severe problems, and 5= extreme problems. Higher scores indicated greater levels of problems across each of the five dimensions. | Up to 30 months |

| Time to definitive deterioration of the ECOG performance status | Time to definitive deterioration of the ECOG PS by one category of the score. The ECOG PS is a measure of functional status. It ranges from 0 to 5, with 0 denoting perfect health and 5 death. A deterioration is considered definitive if no improvements in the ECOG PS status is observed at any subsequent time of measurement during the treatment period following the time point where the deterioration is observed. | Up to 30 months |
