Researchers want to know if intismeran autogene (the study treatment) given with pembrolizumab and chemotherapy can treat metastatic treatment-naive squamous non-small cell lung cancer (NSCLC). Intismeran autogene is designed to help a person's immune system attack their specific cancer.
The goal of this study is to learn if people who receive intismeran autogene with pembrolizumab and chemotherapy live longer overall and without the cancer growing or spreading compared to people who receive placebo with pembrolizumab and chemotherapy. A placebo looks like the study treatment but has no study treatment in it. Using a placebo helps researchers better understand the effects of the study treatment.
Has a histologically or cytologically confirmed diagnosis of squamous non-small cell lung cancer (NSCLC) (Stage IV: M1a, M1b, M1c1, M1c2, AJCC Staging Manual, Version 9). NOTE: Mixed tumors will be characterized by the predominant cell type; however, small cell elements are not permitted.
Has measurable disease per Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by the local site investigator/radiology
Has provided a tissue sample that is collected either at the time of or after the diagnosis of metastatic disease AND is from a site not previously irradiated
Adverse events (AEs) due to previous anticancer therapies must have recovered to ≤Grade 1. Participants with endocrine-related AEs who are adequately treated with hormone replacement or participants who have ≤Grade 2 neuropathy are eligible
Is HIV-infected with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease
Has received prior treatment with a cancer vaccine, including another personalized cancer vaccine (PCV)
Has received prior systemic anticancer therapy for their metastatic NSCLC
Has received prior therapy with an anti-programmed cell death 1 protein (anti-PD-1), anti-programmed cell death ligand 1 (anti-PD-L1), or anti-programmed cell death ligand 2 (anti-PD-L2) agent, or with an agent directed to another stimulatory or coinhibitory T-cell receptor. NOTE: Prior treatment with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent in the neoadjuvant or adjuvant setting for nonmetastatic NSCLC is allowed as long as therapy was completed at least 12 months before diagnosis of metastatic NSCLC

Progression Free Survival (PFS)
PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1). PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by blinded independent central review (BICR) will be presented.
Overall Survival (OS)
OS, defined as the time from randomization to death due to any cause. OS will be presented.
Overall Response Rate (ORR)
ORR is defined as the percentage of participants with Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. The percentage of participants who experience CR or PR as assessed by BICR will be presented.
Duration of Response (DOR)
For participants who demonstrate a confirmed Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. DOR as assessed by BICR will be presented.
Number of Participants who Experience an Adverse Event (AE)
An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. The number of participants who experience an AE will be presented.
Number of Participants who Discontinue Study Intervention Due to an AE
An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. The number of participants who discontinue study intervention due to an AE will be presented.
