Brief Summary:

This study will evaluate the efficacy, safety, pharmacokinetics, immunogenicity and

biomarkers of RO7198457 plus atezolizumab compared with atezolizumab alone in patients with

Stage II-III non-small cell lung cancer (NSCLC) who are circulating tumor DNA (ctDNA)

positive following surgical resection and have received standard-of-care adjuvant

platinum-doublet chemotherapy.


Inclusion Criteria:

- Age >= 18 years;

- Resected Stage II-III Non-small Cell Lung Cancer (NSCLC) per American Joint Committee

on Cancer staging criteria, 8th revised edition;

- Complete R0 resection of Stage II or III NSCLC prior to enrollment and adequate

recovery from surgery;

- Pathological evaluation of mediastinal lymph nodes preoperatively or intraoperatively;

- ctDNA (circulating tumor DNA) identified in plasma after resection of Stage II-III

NSCLC and prior to start of adjuvant platinum-doublet therapy, as determined by

central testing;

- Treatment with at least two cycles of adjuvant platinum-doublet chemotherapy regimens

for resected NSCLC;

- No unequivocal evidence of disease after surgery and adjuvant platinum-doublet

chemotherapy, as assessed on imaging (computed tomography [CT] scan or magnetic

resonance imaging [MRI]) within 28 days prior to randomization;

- Availability of adequate tumor material;

- Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1;

- Adequate hematologic and end-organ function;

- Negative HIV test at screening;

- Negative hepatitis B test at screening;

- Negative hepatitis C test at screening.

Exclusion Criteria:

- Participants with a known mutation in exons 18-21 of epidermal growth factor receptor

(EGFR) or with a known anaplastic lymphoma kinase (ALK) or reactive oxygen species

(ROS) alteration;

- History of malignancy other than disease under study within 5 years prior to

enrollment, with the exception of malignancies with a negligible risk of metastasis or

death, such as adequately treated carcinoma in situ of the cervix, non-melanoma skin

cancer, localized prostate cancer, ductal carcinoma in situ, or Stage I uterine


- Induction and neoadjuvant systemic therapy prior to resection of NSCLC;

- Radiotherapy prior to or after resection of NSCLC;

- Prior systemic investigational therapy;

- Prior anti-CTLA-4, anti-PD-1, and anti-PD-L1 therapeutic antibodies, or a cancer


- Treatment with systemic immunostimulatory agents within 6 weeks or 5 drug elimination

half-lives, prior to initiation of study treatment;

- Treatment with systemic immunosuppressive medication within 2 weeks prior to

initiation of study treatment or anticipation of need for systemic immunosuppressive

medication during study treatment;

- Treatment with monoamine oxidase inhibitors (MAOIs) within 3 weeks prior to initiation

of study treatment or requirement for ongoing treatment with MAOIs;

- Active or history of autoimmune disease or immune deficiency;

- Known primary immunodeficiencies, either cellular or combined T-cell and B-cell


- History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced

pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening

chest CT scan;

- Significant cardiovascular disease;

- Major surgical procedure, other than for diagnosis or for resection of disease under

current study, within 4 weeks prior to initiation of study treatment, or anticipation

of need for a major surgical procedure during the study;

- Known active or latent tuberculosis infection;

- Recent acute infection;

- Treatment with a live, attenuated vaccine within 4 weeks prior to initiation of study

treatment, or anticipation of need for such a vaccine during study treatment or within

5 months after the final dose of study treatment;

- Prior allogeneic stem cell or solid organ transplantation;

- Any other disease, metabolic dysfunction, physical examination finding, or clinical

laboratory finding that contraindicates the use of an investigational drug, may affect

the interpretation of the results, or may render the participants at high risk from

treatment complications;

- Known clinically significant liver disease;

- Previous splenectomy;

- History of severe allergic anaphylactic reactions to chimeric or humanized antibodies

or fusion proteins;

- Known hypersensitivity to Chinese hamster ovary cell products or any component of the

atezolizumab formulation;

- Known allergy or hypersensitivity to any component of RO7198457;

- Pregnant or lactating women.


Primary outcome:

1. Disease-free Survival (DFS) (Time Frame - Up to 62 months):
DFS as assessed by the investigator, is defined as the time from randomization to the date of first documented recurrence of NSCLC or occurrence of new primary NSCLC or death due to any cause, whichever occurs first.

Secondary outcome:

1. Percentage of Participants with Adverse Events (AEs) and Serious AEs (SAEs) determined according to National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 (NCI CTCAE v5.0) (Time Frame - Up to 90 days after the final dose of study drug or until initiation of another systemic anti-cancer therapy (up to approximately 62 months))

2. Plasma Concentrations of RNA at Specified Timepoints (Time Frame - Arm B: Days 1, 8, 15, 22 of Cycle 1 (each cycle is 28 days), Day 1 of Cycle 2, 3, 5, 7, 9, 11 and treatment discontinuation (TD) visit (up to 12 months))

3. Plasma Concentrations of (R)-N,N,N-trimethyl-2,3-dioleyloxy-1-propanaminium chloride (DOTMA) at Specified Timepoints (Time Frame - Arm B: Days 1, 8, 15, 22 of Cycle 1 (each cycle is 28 days), Day 1 of Cycle 2, 3, 5, 7, 9, 11 and treatment discontinuation (TD) visit (up to 12 months))

4. Maximum Serum Concentration (Cmax) of Atezolizumab at Specified Timepoints (Time Frame - Arm A and Arm B: Day 1 of Cycles 1-4 (each cycle is 28 days) and at TD visit (up to 12 months))

5. Minimum Serum Concentration (Cmin) of Atezolizumab at Specified Timepoints (Time Frame - Arm A and Arm B: Day 1 of Cycles 1-4 (each cycle is 28 days) and at TD visit (up to 12 months))

6. Change from Baseline in Number of Participants With Anti-drug Antibodies (ADA) to Atezolizumab (Time Frame - Arm A and Arm B: Baseline, Day 1 of Cycles 1-4 (each cycle is 28 days) and at TD visit (up to 12 months))
