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

Trial Status: Active

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).

Inclusion Criteria

  • Participant must have histologically or cytologically confirmed, locally advanced or metastatic non-small cell lung cancer (NSCLC) not amenable to curative therapy
  • Participant must have a tumor that was previously determined to have 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. The biopsy must have been obtained at or after the diagnosis of advanced disease
  • Unstained tumor tissue (in a quantity sufficient to allow for central analysis of epidermal growth factor receptor (EGFR) mutation status, see Laboratory Manual) and blood (for circulating tumor deoxyribonucleic acid [ctDNA], digital droplet polymerase chain reaction [ddPCR], and pharmacogenomic analysis), both collected at or after the diagnosis of locally advanced or metastatic NSCLC, must be provided
  • 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 for locally advanced or metastatic disease (adjuvant or neoadjuvant therapy 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 has spinal cord compression that has not been definitively treated with surgery or radiation or requires steroid treatment within 2 weeks prior to randomization
  • 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

Status: ACTIVE

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).
