A Study of Amivantamab and Lazertinib Combination Therapy Versus Osimertinib in Locally Advanced or Metastatic Non-Small Cell Lung Cancer

Phase 3
Active, not recruiting
Conditions
Carcinoma, Non-Small-Cell Lung
Interventions
Registration Number
NCT04487080
Lead Sponsor
Janssen Research & Development, LLC
Brief Summary

The purpose of this study is to assess the efficacy of the amivantamab and lazertinib combination, compared with osimertinib, in participants with epidermal growth factor receptor (EGFR) mutation (Exon 19 deletions \[Exon 19del\] or Exon 21 L858R substitution) positive, locally advanced or metastatic non-small cell lung cancer (NSCLC).

Detailed Description

Worldwide, lung cancer is the most commonly diagnosed cancer. In NSCLC the most prevalent actionable driver mutations result in the activation of epidermal growth factor receptor (EGFR). Osimertinib and Lazertinib are EGFR tyrosine kinase inhibitors (TKIs). Amivantamab is a novel bispecific antibody that targets the extracellular domain of both EGFR and MET and can inhibit tumor growth driven by EGFR and mesenchymal-epithelial transition (MET) receptors. Lazertinib inhibits primary activating Exon 19dell and Exon 21 L858R substitution EGFR mutations, and the EGFR T790M+ resistance mutation. The hypothesis is that the amivantamab and lazertinib combination (Arm A) will demonstrate superior PFS compared with single-agent osimertinib (Arm B). The study consists of 3 phases: Screening Phase, Treatment Phase and Follow-up Phase. Participants will undergo response evaluation criteria in solid tumors (RECIST 1.1), pharmacokinetics, and safety evaluations (adverse events, laboratory tests, vital sign measurements, physical examinations).

Inclusion Criteria
  • Participant must have newly diagnosed histologically or cytologically confirmed, locally advanced or metastatic non-small cell lung cancer (NSCLC) that is treatment naive and not amenable to curative therapy including surgical resection or chemoradiation
  • The tumor harbors exon 19 deletions (Exon 19del) or Exon 21 L858R substitution, as detected by an food and drug administration (FDA)-approved or other validated test in a clinical laboratory improvement amendments (CLIA) certified laboratory (sites in the United states [US]) or an accredited local laboratory (sites outside of the US) in accordance with site standard of care
  • Mandatory submission of unstained tissue from tumor (in a quantity sufficient to allow for central analysis of EGFR mutation status and blood (for circulating tumor deoxyribonucleic acid [ctDNA], digital droplet polymerase chain reaction [ddPCR], and pharmacogenomic analysis)
  • Any toxicities from prior anticancer therapy must have resolved to common terminology criteria for adverse events (CTCAE) Grade 1 or baseline level
  • Participant must have at least 1 measurable lesion, according to response evaluation criteria in solid tumors (RECIST) v1.1 that has not been previously irradiated. Measurable lesions should not have been biopsied during screening, but if only 1 non-irradiated measurable lesion exists, it may undergo a diagnostic biopsy and be acceptable as a target lesion, provided the baseline tumor assessment scans are performed at least 14 days after the biopsy
Exclusion Criteria
  • Participant has received any prior systemic treatment at any time for locally advanced Stage III or metastatic Stage IV disease (adjuvant or neoadjuvant therapy for Stage I or II disease is allowed, if administered more than 12 months prior to the development of locally advanced or metastatic disease)
  • Participant has an active or past medical history of leptomeningeal disease
  • Participant with untreated spinal cord compression. A participant that has been definitively treated with surgery or radiation and has a stable neurological status for at least 2 weeks prior to randomization is eligible provided they are off corticosteroid treatment or receiving low-dose corticosteroid treatment less than or equal to (<=) 10 milligrams per day (mg/day) prednisone or equivalent
  • Participant has an active or past medical history of interstitial lung disease (ILD)/pneumonitis, including drug-induced or radiation ILD/pneumonitis
  • Participant has known allergy, hypersensitivity, or intolerance to the excipients used in formulation of amivantamab, lazertinib, or osimertinib, or any contraindication to the use of osimertinib
  • Participant has symptomatic brain metastases. A participant with asymptomatic or previously treated and stable brain metastases may participate in this study

Primary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 as Assessed by Blinded Independent Central Review (BICR)From randomization to either disease progression or death whichever occurs first (up to 32.8 months)

PFS was defined as the time from randomization until the date of objective disease progression based on BICR using RECIST version 1.1 or death (by any cause) the absence of progression, whichever came first. Disease progression was defined using RECIST 1.1 as a 20 percent (%) increase in the sum of diameters of target measurable lesions above the smallest sum observed, with a minimum absolute increase of 5 millimeters (mL). Participants who have not progressed or have not died at the time of analysis were censored at the time of the latest date of their last evaluable RECIST version 1.1 assessment.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS)Approximately 60 months (time from the date of randomization until the date of death due to any cause)

Overall Survival is defined as the time from the date of randomization to the date of participant's death due to any cause.

Objective Response Rate (ORR)Approximately 32.8 months

ORR is defined as the percentage of participants who achieve either a complete response (CR) or partial response (PR) as defined by BICR using RECIST v1.1 criteria.

Duration of Response (DOR)Approximately 32.8 months

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 as determined by the investigator using RECIST v1.1 criteria.

Progression-Free Survival After First Subsequent Therapy (PFS2)Approximately 60 months

The 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.

Time to Symptomatic Progression (TTSP)Approximately 60 months

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.

Incidence and Severity of Adverse Events (AEs)Approximately 60 months

Incidence and severity of treatment emergent adverse events (TEAEs) will be reported. Any adverse event occurring at or after the initial administration of study treatment through the day of last dose plus 30 days, or until the start of subsequent anticancer therapy (if earlier), is considered to be treatment emergent.

Intracranial PFSApproximately 60 months

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.

Number of participants with clinical laboratory abnormalities (serum chemistry, hematology, blood coagulation, and urine samples) will be reported.

Number of Participants With Anti-Amivantamab AntibodiesApproximately 60 months

Number of participants with antibodies to amivantamab will be reported.

Number of Participants With Vital Signs AbnormalitiesApproximately 60 months

Number of participants with vital signs abnormalities (temperature, heart rate, respiratory rate, oxygen saturation, blood pressure) will be reported.

Plasma Concentration of LazertinibApproximately 60 months

Plasma samples will be analyzed to determine concentrations of Lazertinib.

Number of Participants With Physical Examination AbnormalitiesApproximately 60 months

Number of participants with physical examination abnormalities will be reported.

Serum Concentration of AmivantamabApproximately 60 months
