The purpose of this study is to determine the recommended Phase 2 dose (RP2D) of JNJ-64041757 a live attenuated double deleted (LADD) Listeria monocytogenes (bacteria in which two virulence genes, which encode molecules that help cause disease, have been removed) when administered intravenously to participants with advanced (Stage IIIb) or metastatic (Stage IV) NSCLC (adenocarcinoma).
This is a first-in-human (FIH), Phase 1, open-label, multicenter and 2-part study in participants with advanced (Stage IIIb) or metastatic (Stage IV) non-small cell lung cancer (NSCLC) (adenocarcinoma). Part 1 of study will be Dose Escalation phase to determine the recommended Phase 2 dose (RP2D) based on safety and pharmacodynamic assessments and Part 2 will be Dose Expansion Phase to evaluate 2 expansion cohorts (Cohort 2A and 2B) after the RP2D for JNJ-64041757 is determined in Part 1. The study will consist of a Screening Period (from signing of informed consent until immediately before the first dose), an open-label Treatment Period (from the first dose of study drug until the End-of-Treatment Visit); and a Post treatment Follow-up Period (after the End-of Treatment Visit until study discontinuation). Dose limiting toxicity (DLT) in part 1, antigen-specific T-cell response in part 2 and incidence of adverse events in both the parts will be primarily evaluated.

JNJ-64041757 will be administered IV at a lower dose in Cohort 1A (1x10\^8 colony forming units \[CFU\] ) and at a higher dose in Cohort 1B (1x10\^9 CFU)
JNJ-64041757 will be administered intravenously (IV) once every 21 days at the recommended dose as determined in Cohort 1A or 1B.

Part 1: Incidence of Dose-limiting toxicity (DLT)
Percentage of participants who experienced DLT will be evaluated. The DLT dose level is defined as an unacceptable level of toxicity as evidenced by a DLT rate of greater than or equal to (\>=) 33%.
Time frame: First 21 days after the first infusion
Part 2: Antigen-specific T-cell Response
Biomarker analyses leukapheresis will be performed to evaluate immune responses to the vaccine after an single IV immunization.
Time frame: up to 1 year
Part 1 and Part 2: Incidence of Adverse Events (AEs)
An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly; suspected transmission of any infectious agent via a medicinal product and medically important. Incidence was defined as the number of participants who experienced an adverse event within their period of participation in this study. Severity of adverse events will be assessed using National Cancer Institute Common Terminology Criteria for Adverse Events (NCICTCAE).
Time frame: From signing of informed consent form to 30 days after last dose of study drug
Part 1 and Part 2: Objective Response Rate (ORR)
Objective response rate is defined as the percentage of participants who achieve complete response (CR) or partial response (PR), as assessed by the investigator.
Time frame: Baseline up to 30 days after last dose of study drug
Part 1 and Part 2: Duration of Response (DOR)
Duration of response will be calculated from the date of initial documentation of a response (CR or PR) to the date of first documented evidence of progressive disease (or relapse for subjects who experience CR during the study) or death.

Part 1 and Part 2: Progression-free Survival (PFS)
Progression-free survival is defined as the duration from the date of first dose of study drug until the date of first documented evidence of progressive disease (or relapse for subjects who experience CR during the study) or death, whichever comes first.
Time frame: Baseline up to 30 days after last dose of study drug
Part 1 and Part 2: Blood Culture Assessment of JNJ-64041757
This assessment will include the reporting of surveillance blood cultures (peripherally drawn, and through venous access device \[if applicable\]) for 1 year after the completion of JNJ-64041757 therapy.
Time frame: Periodically during treatment and up to one year after End of Treatment (EOT) visit
Part 1 and Part 2: Shedding Profile of JNJ-64041757 From Cultured Samples of Feces, Urine, and Saliva
The shedding profile of JNJ-64041757 will be studied in cultures of (1) feces by stool or rectal swab, (2) urine samples, and (3) saliva samples.
Time frame: During cycle 1 (up to 21 days of treatment period) and at EOT visit (within 30 days after last dose)
