Necitumumab

BACKGROUND: Efficacy of necitumumab [recombinant human monoclonal antibody that blocks the ligand binding epidermal growth factor receptor (EGFR)] in patients with squamous (SQ) non-small-cell lung cancer (NSCLC) has been confirmed in two randomized clinical trials (SQUIRE and JFCM). This study evaluated the association between efficacy and initial skin toxicity with necitumumab treatment by analyzing pooled data from two clinical trials (SQUIRE and JFCM). MATERIALS AND METHODS: Data of 635 patients with SQ-NSCLC (intent-to-treat population) treated with necitumumab plus gemcitabine and cisplatin (N + GC) were pooled from two clinical trials (SQUIRE and JFCM)...

Necitumumab enhances antitumor immunity by decreasing the PD-L1 expression; it is expected to improve the prognosis of patients treated with an immune checkpoint inhibitor(ICI)by inhibiting the IL-8 expression. Since the combined effect of necitumumab and PD-L1 inhibitor was confirmed in an in vivo study conducted in transgenic mice, further antitumor effects can be expected by the combined use of necitumumab and ICI.

INTRODUCTION: Necitumumab plus gemcitabine and cisplatin (GCN) is a standard therapy for patients with advanced lung squamous cell carcinoma (LSqCC). However, the efficacy and tolerability of GCN in second-line or later treatment for patients previously treated with immune checkpoint inhibitors (ICIs) remain unknown. METHODS: This multicenter, retrospective, cohort study assessed the efficacy and tolerability of GCN initiated between November 1, 2019 and March 31, 2022 as second-line to fourth-line treatment in patients with advanced LSqCC who had been pretreated with ICIs...

BACKGROUND: Platinum-based combination therapy plus a programmed cell death 1/programmed cell death ligand 1 (PD-1/PD-L1) inhibitor is a standard treatment for patients with stage IV non-small cell lung cancer. However, necitumumab is used with gemcitabine and cisplatin as a first-line treatment option for squamous cell lung cancer (SqCLC). Furthermore, the combination of necitumumab with immune checkpoint inhibitors has the potential to enhance tumor immunity and improve the therapeutic effect...

BACKGROUND: The efficacy and safety of the anti-EGFR antibody necitumumab combined with gemcitabine and cisplatin (N + GC) in the first-line treatment of advanced lung squamous cell carcinoma (LSCC) have been proven. However, the efficacy and safety of N + GC in the second line or later treatment remain unclear. METHODS: Eleven patients who received N + GC for advanced-stage or recurrent LSCC were enrolled. We retrospectively assessed the patients' clinical characteristics and efficacy and safety of treatment...

BACKGROUND: The advances in the lung cancer screening methods and therapeutics, together with awareness towards deleterious habits, such as smoking, is increasing the overall survival with better quality of life for the patients. However, lung cancer is still one of the most common and fatal neoplasm with a high incidence and consequently burden to public health worldwide. Thus, based on guidelines and recent phases II and III clinical trials studies, this manuscript summarizes the current treatment sequencing strategies in lung cancer...

The problems with anticancer therapy are resistance and toxicity. From 3000 Cisplatin derivatives tested as antitumor agents, most of them have been rejected, due to toxicity. The aim of current study is the comparison of therapeutic combinations of the currently applied in clinical practice: Cisplatin, Carboplatin, Oxaliplatin, Nedaplatin, Lobaplatin, Heptaplatin, and Satraplatin. The literature data show that the strategies for the development of platinum anticancer agents and bypassing of resistance to Cisplatin derivatives and their toxicity are: combination therapy, Pt IV prodrugs, the targeted nanocarriers...

Purpose: An underlying factor for the failure of several clinical trials of anti-epidermal growth factor receptor (EGFR) therapies is the lack of an effective method to identify patients who overexpress EGFR protein. The quantitative dot blot method (QDB) was used to measure EGFR protein levels objectively, absolutely, and quantitatively. Its feasibility was evaluated for the prognosis of overall survival (OS) of patients with gastric cancer. Materials and Methods: Slices of 2×5 μm from formalin-fixed paraffin-embedded gastric cancer specimens were used to extract total tissue lysates for QDB measurement...

A 72-year-old man, diagnosed with advanced lung squamous cell carcinoma, was administered of cisplatin plus gemcitabine with necitumumab, a human monoclonal antibody that binds to the epidermal growth factor receptor (EGFR), as a sixth-line treatment. Tumor shrinkage was observed, but asymptomatic grade 4 hypomagnesemia occurred on day 8 of the second cycle. He received magnesium replenishment and hypomagnesemia recovered on day 40, but tumor progression was observed during the period of magnesium correction...

The epidermal growth factor receptor (EGFR) belongs to the tyrosine kinase receptors family and is present in the epithelial cell membrane. Its endogenous activation occurs through the binding of different endogenous ligands, including the epidermal growth factor (EGF), leading to signaling cascades able to maintain normal cellular functions. Although involved in the development and maintenance of tissues in normal conditions, when EGFR is overexpressed, it stimulates the growth and progression of tumors, resulting in angiogenesis, invasion and metastasis, through some main cascades such as Ras/Raf/MAPK, PIK-3/AKT, PLC-PKC and STAT...

BACKGROUND: Whether necitumumab combined with platinum-based chemotherapy (NC) for treating stage IV non-small cell lung cancer (NSCLC) as a first-line treatment could enhance antitumor effectiveness compared with platinum-based chemotherapy alone (CA) treatment is still controversial. The antitumor effectiveness and toxicity of the two treatments were compared in this meta-analysis. METHODS: We searched in PubMed, ScienceDirect, Scopus, Web of Science, Ovid MEDLINE, the Cochrane Library, Embase, and Google Scholar to acquire applicable articles...

Epidermal growth factor receptor (EGFR) is a tyrosine kinase receptor involved in homeostatic regulation of normal cells and carcinogenesis of epithelial malignancies. With rapid development of the precision medicine era, a series of new therapies targeting EGFR are underway. Four EGFR monoclonal antibody drugs (cetuximab, panitumumab, nimotuzumab, and necitumumab) are already on the market, and a dozen other EGFR monoclonal antibodies are in clinical trials. Here, we comprehensively review the newly identified biological properties and anti-tumor mechanisms of EGFR monoclonal antibodies...

OBJECTIVES: Efficacy and safety of necitumumab when combined with pembrolizumab was assessed in patients with Stage IV non-small cell lung cancer (NSCLC) of squamous and nonsquamous histology, who had progressed after treatment with a platinum-based doublet. MATERIALS AND METHODS: This single-arm, multicenter, phase Ib study had a dose-finding phase, in which escalating doses of necitumumab (600 mg and 800 mg IV) were administered on Day 1 and 8 every 3 weeks (Q3W) in combination with pembrolizumab (200 mg IV) on Day 1 Q3W, and expansion cohorts...

OBJECTIVES: Necitumumab, an anti-EGFR antibody, and abemaciclib, a CDK4/6 inhibitor, have shown activity in patients with non-small cell lung cancer (NSCLC) and have non-overlapping toxicities. A 2-part, single-arm, multicenter, phase 1b trial was conducted to test the safety and efficacy of necitumumab plus abemaciclib in patients with advanced NSCLC who had received ≤2 lines of chemotherapy, including a platinum-based one. MATERIALS AND METHODS: Part A was a dose-escalation phase for abemaciclib (100, 150, 200 mg, Q12 H) in combination with necitumumab 800 mg D1D8 Q3W to determine the recommended dose for the expansion cohort, Part B...

OBJECTIVES: Necitumumab is a second-generation, recombinant, human IgG1-type monoclonal antibody directed against EGFR approved for adult patients with metastatic squamous non-small cell lung cancer (NSCLC) in combination with gemcitabine and cisplatin. This study assessed the efficacy and safety of albumin-bound paclitaxel (nab-paclitaxel) and carboplatin in combination with necitumumab as first-line therapy in patients with stage IV squamous NSCLC. MATERIALS AND METHODS: The treatment regimen comprised triplet induction with necitumumab (800 mg) with nab-paclitaxel (100 mg/m2 ) and carboplatin (AUC 6 mg*min/mL) for 4 cycles, followed by doublet maintenance with necitumumab and nab-paclitaxel with a 3-weekly schedule until progressive disease or unacceptable toxicity...

A number of mutations in the epidermal growth factor receptor (EGFR) have been identified that imparts resistance to anti-EGFR monoclonal antibodies (mAbs) in clinical and preclinical samples. Primary or acquired resistance to targeted therapy will eventually limit the clinical benefit of anticancer mAbs. The aim of the current study was to perform computational analysis to investigate the structural implications of the EGFR somatic mutations on its complexes with the four anti-EGFR mAbs (Cetuximab, Panitumumab, Necitumumab, and Matuzumab)...

BACKGROUND: Although the epidermal growth factor receptor (EGFR) and its truncated, autoactive mutant EGFRvIII are bona fide drivers of tumorigenesis in some gliomas, therapeutic antibodies developed to neutralize this axis have not improved patient survival in a limited number of trials. Previous studies using cells transduced to exogenously express EGFRvIII may have compromised mechanistic studies of anti-EGFR therapeutics. Therefore, we re-assessed the activity of clinical EGFR antibodies in patient-derived gliomaspheres that endogenously express EGFRvIII...

OBJECTIVES: This open-label, multicenter, phase 1b/2 study assessed necitumumab plus gemcitabine and cisplatin (GC + N) in patients with previously untreated squamous non-small cell lung cancer in Japan. MATERIALS AND METHODS: The phase 1b part determined the gemcitabine dose for the phase 2 part, in which patients were randomized 1:1 to GC + N or gemcitabine and cisplatin (GC) (gemcitabine 1250 mg/m2 on days 1 and 8; cisplatin 75 mg/m2 on day 1 of maximum four 3-week cycles; nectimumab 800 mg on days 1 and 8 of a 3-week cycle continued until progressive disease or unacceptable toxicity)...
