Clinical Trial Summary

The purpose of this study is to assess the efficacy of adding lazertinib to amivantamab, carboplatin, and pemetrexed (LACP/ACP-L dosing strategies) and amivantamab, carboplatin and pemetrexed (ACP) compared with carboplatin and pemetrexed (CP) in participants with locally advanced or metastatic epidermal growth factor receptor (EGFR) Exon 19del or Exon 21 L858R substitution non-small cell lung cancer (NSCLC) after osimertinib failure. The purpose of the extension cohort is to further describe the safety and efficacy for the ACP-L dosing schedule versus ACP with additional data.

Description:

Lung cancer is one of the most common types of cancer and is the most common cause of death from cancer. NSCLC accounts for approximately 85 percent (%) of lung cancers. Advanced NSCLC is a serious terminal illness that accounts for approximately 20% of all cancer mortality, and until recently had a median overall survival (OS) of approximately 1 year. Amivantamab (JNJ-61186372) is a low fucose, fully human immunoglobulin (IgG)1-based bispecific antibody directed against EGFR and mesenchymal-epithelial transition (MET) tyrosine kinase receptors. It shows clinical activity against tumors with primary activating EGFR mutations Exon 19del and Exon 21 L858R substitution. Lazertinib (JNJ-73841937; YH-25448) is an oral, highly potent, third-generation EGFR tyrosine kinase inhibitor (TKI). It selectively inhibits both primary activating EGFR mutations (Exon 19del, Exon 21 L858R substitution) and the EGFR T790M resistance mutation, with less inhibition of wild-type EGFR. The study consists of a Screening Phase (up to 28 days), a Treatment Phase (from randomization until the End of Treatment visit) and a Follow-up Phase (from End of Treatment Visit until the end of study, death, lost to follow-up, or withdrawal of consent, whichever comes first). Safety will be assessed by physical examinations, laboratory tests, vital signs, electrocardiograms, Eastern Cooperative Oncology Group (ECOG) performance status, and monitoring of adverse events (AEs). The total duration of the study is up to 48 months.

Eligibility

Inclusion Criteria:

• Participant must have at least 1 measurable lesion, according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, that has not been previously irradiated
• Participant must have histologically or cytologically confirmed, locally advanced or metastatic, non-squamous non-small cell lung cancer (NSCLC), characterized at or after the time of locally advanced or metastatic disease diagnosis by either epidermal growth factor receptor (EGFR) Exon 19del or Exon 21 L858R mutation
• A participant with a history of brain metastases must have had all lesions treated as clinically indicated (that is, no current indication for further definitive local therapy). Any definitive local therapy to brain metastases must have been completed at least 14 days prior to randomization and the participant can be receiving no greater than10 milligrams (mg) prednisone or equivalent daily for the treatment of intracranial disease
• Participant must have Eastern Cooperative Oncology Group (ECOG) status of 0 or 1
• Any toxicities from prior systemic anticancer therapy must have resolved to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5.0 Grade 1 or baseline level (except for alopecia [any grade], Grade <= 2 peripheral neuropathy, or Grade <= 2 hypothyroidism stable on hormone replacement)
• A woman of childbearing potential must have a negative serum pregnancy test at screening and within 72 hours of the first dose of study treatment and must agree to further serum or urine pregnancy tests during the study
• Participant must have progressed on or after osimertinib monotherapy as the most recent line of treatment. Osimertinib must have been administered as either the first-line treatment for locally advanced or metastatic disease or in the second- line setting after prior treatment with first- or second-generation EGFR tyrosine kinase inhibitor (TKI) as a monotherapy. Participants who received either neoadjuvant and/or adjuvant treatment of any type are eligible if progression to locally advanced or metastatic disease occurred at least 12 months after the last dose of such therapy and then the participant progressed on or after osimertinib in the locally advanced or metastatic setting. Treatment with osimertinib must be discontinued at least 8 days (4 half-lives) prior to randomization (that is last dose no later than Day -8)

Exclusion Criteria:

• Participant received radiotherapy for palliative treatment of NSCLC less than 14 days prior to randomization
• Participant with symptomatic or progressive brain metastases
• Participant has history of or current evidence of leptomeningeal disease, or participant has spinal cord compression not definitively treated with surgery or radiation
• Participant has known small cell transformation
• Participant has a medical history of interstitial lung disease (ILD), including drug-induced ILD or radiation pneumonitis
• Participant has a history of clinically significant cardiovascular disease including, but not limited to diagnosis of deep vein thrombosis or pulmonary embolism within 4 weeks prior to randomization; myocardial infarction; unstable angina; stroke; transient ischemic attack; coronary/peripheral artery bypass graft; or acute coronary syndrome. Participant has a significant genetic predisposition to venous thromboembolic events. Participant has a prior history of venous thromboembolic events and is not on appropriate therapeutic anticoagulation as per National Comprehensive Cancer Network or local guidelines

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-Free Survival (PFS) According to RECIST v1.1 Guidelines as Assessed by Blinded Independent Central Review (BICR)	PFS is defined as the time from randomization until the date of objective disease progression or death, whichever comes first, using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.	Up to 17 months
Secondary	Objective Response as Assessed by BICR	Objective response is defined as the percentage of participants who achieve either a complete response (CR) or partial response (PR) as their best response as defined by BICR using RECIST v1.1 criteria.	Up to 17 months
Secondary	Overall Survival (OS)	Overall Survival is defined as the time from the date of randomization to the date of participant's death due to any cause.	Up to 48 months
Secondary	Duration of Response (DoR)	DoR is defined as the time from the date of first documented response (CR or PR) until the date of documented progression or death, whichever comes first, only for participants who achieve CR or PR.	Up to 17 months
Secondary	Time to Subsequent Therapy (TTST)	TTST is defined as the time from the date of randomization to the start date of the subsequent anti-cancer therapy following study treatment discontinuation, or death whichever comes first.	Up to 17 months
Secondary	Progression-Free Survival After First Subsequent Therapy (PFS2)	PFS2 is defined as the time from randomization until the date of second objective disease progression, after initiation of subsequent anticancer therapy, based on investigator assessment (after that used for PFS) or death, whichever comes first.	Up to 17 months
Secondary	Time to Symptomatic Progression (TTSP)	TTSP is defined as the time from randomization to documentation in the electronic case report form (eCRF) of any of the following (whichever occurs earlier): onset of new symptoms or symptom worsening that is considered by the investigator to be related to lung cancer and requires either a change in anticancer treatment and/or clinical intervention to manage symptoms.	Up to 17 months
Secondary	Intracranial PFS	Intracranial PFS is defined as the time from randomization until the date of objective intracranial disease progression or death, whichever comes first, based on BICR using RECIST v1.1.	Up to 17 months
Secondary	Number of Participants with Adverse Events (AEs)	An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.	Up to 48 months
Secondary	Number of Participants with Clinical Laboratory Abnormalities	Number of participants with clinical laboratory abnormalities (serum chemistry, hematology, blood coagulation, and urinalysis) will be reported.	Up to 48 months
Secondary	Serum Concentration of Amivantamab	Serum samples will be analyzed to determine concentrations of amivantamab.	Up to 17 months
Secondary	Plasma Concentration of Lazertinib	Plasma samples will be analyzed to determine concentrations of lazertinib.	Up to 17 months
Secondary	Number of Participants with Anti-Amivantamab Antibodies	Number of participants with anti-amivantamab antibodies will be reported.	Up to 17 months
Secondary	Non-Small Cell Lung Cancer - Symptom Assessment Questionnaire (NSCLC-SAQ)	NSCLC-SAQ is a 7-item PRO measure designed for use in adults to assess symptoms of advanced non-small cell lung cancer (NSCLC). The NSCLC-SAQ has a seven-day recall period. It contains five domains and accompanying items that will be identified as symptoms of NSCLC: cough (1 item), pain (2 items), dyspnea (1 item), fatigue (2 items), and appetite (1 item). Each item uses a response scale between 0 to 4, with higher scores indicating more severe symptomatology. All five of these domains must be non-missing to compute a total score, with a response range from 0 to 20 with higher scores indicating more severe symptomatology.	Up to 17 months
Secondary	European Organization of Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) Score	The EORTC QLQ-C30 includes 30 items in 5 functional scales, 1 global health status scale, 3 symptom scales, and 6 single symptom items. The responses are reported using a verbal rating scale. The item and scale scores are transformed to a 0 to 100 scale. A higher score represents greater HRQoL, better functioning, and more (worse) symptoms.	Up to 17 months
Secondary	Patient Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF)	PROMIS-PF is used to characterize and better understand overall health, level of physical disability, and general well-being. Physical function is a foundation for commonly used general and cancer-specific patient reported outcomes (PRO) measures.	Up to 17 months
