• Part 2: Overall Response Rate (ORR) [ Time Frame: Up to 4 years ]
  ORR is defined as the percentage of participants who have a partial response (PR) or better response as per RECIST v.1.1. PR criteria in solid tumors (RECIST) is greater than or equal to (>=) 30 percent (%) decrease in the sum of the diameters of all index lesions compared with baseline in 2 observations at least 4 weeks apart, in absence of new lesions or unequivocal progression of non-index lesions.

• Part 1 and Part 2: Maximum Observed Plasma Concentration (Cmax) of JNJ-74699157 [ Time Frame: Up to 4 years ]
  Cmax is the maximum observed plasma concentration.
• Part 1 and Part 2: Time to Reach Maximum Observed Plasma Concentration (Tmax) of JNJ-74699157 [ Time Frame: Up to 4 years ]
  Tmax is defined as actual sampling time to reach maximum observed plasma concentration.
• Part 1 and 2: Area Under Plasma-concentration Time Curve from Time 0 to Time of Last Quantifiable Concentration (AUC [0-last]) [ Time Frame: Up to 4 years ]
  AUC (0-last) is the area under the plasma concentration-time curve from time zero to last observed quantifiable concentration.
• Part 1 and 2: Percentage of KRAS G12C Protein in Tumor Tissue Covalently Bound with JNJ-74699157 or its Metabolites [ Time Frame: Up to 4 Years ]
  Percentage of kirsten rat sarcoma virus homolog (KRAS) glycine-to-cysteine (G12C) protein in tumor tissue covalently bound with JNJ-74699157 or its metabolites will be evaluated using mass spectroscopy.
• Part 1: Overall Response Rate [ Time Frame: Up to 4 years ]
  ORR is defined as the percentage of participants who have a PR or better response as per RECIST v.1.1. PR criteria in solid tumors (RECIST) is >=30 percent % decrease in the sum of the diameters of all index lesions compared with baseline in 2 observations at least 4 weeks apart, in absence of new lesions or unequivocal progression of non-index lesions.
• Part 1 and Part 2: Duration of Response (DOR) [ Time Frame: Up to 4 years ]
  DOR is defined as the duration from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease (PD), as defined in the RECIST v1.1, or death due to any cause, whichever occurs first. PD is assessed if the sum of the diameters has increased by >=20% and >=5 millimeter (mm) from nadir (including baseline if it is the smallest sum).
• Change From Baseline in QTc Interval Based on the Fridericia Correction (QTcF) Method [ Time Frame: Baseline up to 4 years ]
  Change from baseline in QTcF intervals will be assessed.

• Neoplasms
• Advanced Solid Tumors
• Non-small Cell Lung Cancer
• Colorectal Cancer

• Experimental: Part 1: Dose Escalation
  Participants with advanced solid tumors harboring the kirsten rat sarcoma virus homolog (KRAS) glycine-to-cysteine (G12C) mutation will receive oral administration of JNJ-74699157. The dose levels will be escalated sequentially based on the decisions of the Study Evaluation Team (SET) until the recommended Phase 2 Dose (RP2D) has been identified.
  Intervention: Drug: JNJ-74699157
• Experimental: Part 2: Dose Expansion
  Two groups of participants with either non-small cell lung cancer or other solid tumors harboring KRAS G12C mutation will receive JNJ-74699157 at RP2D determined in Part 1.
  Intervention: Drug: JNJ-74699157

Inclusion Criteria:

• Kirsten rat sarcoma virus homolog (KRAS) glycine-to-cysteine (G12C) mutation in tumor tissue or blood
• Histological documentation of disease: Part 1: Histologically or cytologically confirmed solid tumor malignancy that is metastatic or unresectable, Part 2: (a) unresectable, locally advanced (Stage IIIB) or metastatic (Stage IV) non-small cell lung cancer (NSCLC), (b) Solid tumor malignancy other than NSCLC that is metastatic or unresectable
• Received or was ineligible for standard treatment options. For NSCLC: previously received a platinum-containing chemotherapy regimen and an anti- programmed death-ligand 1 (PD1/PDL1) antibody, unless participant refused or was ineligible to receive such therapy; and for colorectal cancer (CRC): previously received at least 2 prior lines of therapy, including a fluoropyrimidine, oxaliplatin, and irinotecan, unless participant refused or was ineligible to receive such therapy. For Participants in France only: NSCLC: Previously received a platinum-containing chemotherapy regimen and an anti-PD1/PDL1 antibody or was ineligible to receive such therapy. CRC: Previously received at least 2 prior lines of therapy, including a fluoropyrimidine, oxaliplatin, and irinotecan or was ineligible to receive such therapy
• Measurable or evaluable disease: Part 1: either measurable or evaluable disease, Part 2: At least 1 measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
• Eastern Cooperative Oncology Group (ECOG) performance status grade of 0 or 1

Exclusion Criteria:

• Symptomatic brain metastases or known leptomeningeal disease; asymptomatic brain metastases are allowed if they have been treated, have been stable for greater than or equal to (>=) 4 weeks as documented by radiographic imaging, and do not require prolonged (greater than [>]14 days) systemic corticosteroid therapy. Participants who have had complete surgical resection of or received stereotactic radiosurgery to less than or equal to (<=) 3 metastatic lesions will be permitted to enroll in the study within 14 days of such treatment if they have recovered from treatment, are clinically stable, and do not require prolonged systemic corticosteroid therapy as noted above
• Prior treatment with an inhibitor specific to KRAS G12C
• Prior solid organ transplantation
• History of malignancy (other than the disease under study) within 2 years before the first administration of study drug. Exceptions include squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy that in the opinion of the investigator, with concurrence with the sponsor's medical monitor, is considered cured with minimal risk of recurrence within 2 years
• Inability to take an orally administered drug, or medical disorder or prior surgical resection that may affect the absorption of the study drug. Such conditions include, but are not limited to, malabsorption syndrome, symptomatic inflammatory bowel disease, partial or complete bowel obstruction, or resection of the stomach or small bowel. If any of these conditions exist, the investigator should discuss with the sponsor to determine participant eligibility
