EGFR Antibody

Necitumumab, IMC-11F8

Tags: cancer cell signaling, lung cancer, phase II, phase I

EGFR Antibody Derived from Yarden Y and Shilo BZ.1

Target

Epidermal growth factor receptor (EGFR) is a member of the ErbB (erythroblastic leukemia viral oncogene homolog) family of receptor tyrosine kinases. EGFR activation occurs in response to ligand stimulation and/or genetic alterations of the EGFR gene, such as somatic mutations, amplifications, or deletions. Activated EGFR induces downstream signaling through the MAPK (mitogen-activated protein kinases), PI3K/AKT (phosphoinositide 3-kinase/v-Akt murine thymoma viral oncogene) and PLCY (phospholipase CY) signal transduction pathways that mediate cell proliferation, cell survival, and cell migration, respectively, thereby contributing to neoplastic transformation and tumor growth.2,3

Molecule

Necitumumab (IMC-11F8) is a recombinant IgG1 human monoclonal antibody designed to bind and block the ligand binding site of EGFR.4-6

Clinical Development

Necitumumab is being investigated in clinical trials in patients with non-small cell lung cancer and in a combination clinical trial in immuno-oncology.

  • Has received prior anticancer therapy with monoclonal antibodies, signal transduction inhibitors, or any therapies targeting EGFR, vascular endothelial growth factor (VEGF), or VEGF receptor
  • Has received previous chemotherapy for advanced NSCLC
  • Has had a major surgery or any investigational therapy in the 4 weeks prior to study entry
  • Has received systemic radiotherapy within 4 weeks prior to study entry or focal radiotherapy within 2 weeks prior to study entry
  • Has symptomatic central nervous system malignancy or metastasis

NCT02411591 Schema

A Single-Arm, Multicenter, Phase 1b Study With an Expansion Cohort to Evaluate Safety and Efficacy of Necitumumab in Combination With Abemaciclib in Treatment of Patients With Stage IV Non-small Cell Lung Cancer (NSCLC)

Key Inclusion Criteria

  • Histologically or cytologically confirmed stage IV NSCLC:
    -
    Part A: Stage IV NSCLC (any type)
    -
    Part B: Stage IV NSCLC (squamous and nonsquamous)
  • Measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
  • The participant must have progressed after platinum-based chemotherapy and have received 1 other prior chemotherapy for advanced and/or metastatic disease or must be judged by the physician as ineligible for further standard second-line chemotherapy. Prior treatment with epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) and anaplastic lymphoma kinase (ALK) inhibitors is mandatory in participants whose tumor has EGFR-activating mutations or ALK translocations. Prior vascular endothelial growth factor/vascular endothelial growth factor receptor (VEGF/VEGFR)-targeting agents and neoadjuvant/adjuvant therapies are permitted
  • The participant has tumor tissue available for biomarker analyses
  • ECOG performance status of 0 to 1
  • Has adequate organ function

Key Exclusion Criteria

  • Currently enrolled in a clinical trial involving an investigational product or nonapproved use of a drug or device. Prior treatment with cyclin-dependent kinase (CDK) 4/6-targeting agents or necitumumab is not permitted
  • Has a serious concomitant systemic disorder or significant cardiac disease
  • Has undergone major surgery or received any investigational therapy in the 30 days prior to study enrollment
  • Has undergone chest irradiation within 4 weeks prior to receiving study treatment
  • Has brain metastases that are symptomatic
  • History of arterial or venous embolism within 3 months prior to study enrollment. If the embolism occurred >3 and <6 months, the participant is eligible provided appropriate treatment according to local standard is ensured
  • Has any ongoing or active infection
  • Has a known hypersensitivity to any of the treatment components
  • Has a concurrent active malignancy
  • Has a history of interstitial lung disease
