• Registration Number: NCT04006301
• Lead Sponsor: Janssen Research & Development, LLC

Brief Summary

The purpose of this study is to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of JNJ-74699157 in participants with advanced solid tumors harboring a kirsten rat sarcoma virus homolog (KRAS) glycine-to-cysteine (G12C) mutation (Part 1: Dose escalation) and to determine the safety and preliminary antitumor activity of JNJ-74699157 at the RP2D regimen in participants with advanced solid tumors harboring a KRAS G12C mutation (Part 2: Dose expansion).

Detailed Description

KRAS is one of the most frequently mutated genes in human cancer. KRAS mutations lead to activation of cellular signaling that promotes tumor growth, and KRAS may therefore be a candidate target for anticancer therapy. This study will evaluate JNJ-74699157, a potent and specific, orally bioavailable inhibitor of the glycine-to-cysteine (G12C) mutant KRAS protein, which is found in non-small cell lung cancers and other solid tumor types. This study will enroll participants with advanced solid tumors harboring the KRAS G12C mutation and will be conducted in 2 parts. Part 1 (Dose Escalation) will be carried out in sequential cohorts of single or multiple participants at doses assigned by the study evaluation team to determine the MTD and RP2D of JNJ-74699157. Participants in Part 2 (Dose Expansion) will receive JNJ-74699157 at the RP2D determined in Part 1 to determine the safety and preliminary antitumor activity of the RP2D. Key efficacy assessments include radiographic imaging evaluations, physical examination, and tumor markers. Safety evaluations will include monitoring of adverse events, vital signs, laboratory evaluations, cardiac monitoring and physical examination findings. The study consists of a screening phase, treatment phase, and a post-treatment follow-up phase. An end-of-treatment visit will occur within 30 days of the last dose of study drug or prior to the start of a subsequent anticancer therapy, whichever comes first. The study duration will be up to 4 years.

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

Arm && Interventions

Group	Intervention	Description
Part 2: Dose Expansion	JNJ-74699157	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.
Part 1: Dose Escalation	JNJ-74699157	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.

Primary Outcome Measures

Name	Time	Method
Part 1 and Part 2: Number of Participants with AE's by Severity	Up to 4 years	Severity of AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) criteria: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4: Life threatening consequences; Grade 5: Death.
Part 2: Overall Response Rate (ORR)	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: Number of Participants with Dose-Limiting Toxicity (DLT)	Up to 2 years	DLTs are defined as certain non-hematologic and hematologic toxicities of Grade 3 or higher.
Part 1 and Part 2: Number of Participants with Adverse Events (AEs)	Up to 4 years	An AE is any untoward medical occurrence in a participant who received study drug without regard to causal relationship.

Secondary Outcome Measures

Name	Time	Method
Part 1 and Part 2: Maximum Observed Plasma Concentration (Cmax) of JNJ-74699157	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	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])	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	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	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)	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).
