Matuzumab - CAS 339186-68-4
Catalog number:
Not Intended for Therapeutic Use. For research use only.
Matuzumab is a humanized monoclonal antibody that binds to the epidermal growth factor receptor (EGFR). EGFR existing on the surface of normal and tumor cells binds to EGF (epidermal growth factor) and other EGF family growth factors, which leads to the activation of EGFR. Matuzumab is used as an anti-cancer drug.

1.Metastatic gastric cancer - focus on targeted therapies.

Gastric cancer (GC) is currently the second leading cause of cancer death worldwide; unfortunately, most patients will present with locally advanced or metastatic disease. Despite recent progress in diagnosis, surgery, chemotherapy, and radiotherapy, prognosis remains poor. A better understanding of GC biology and signaling pathways is expected to improve GC therapy, and the integration of targeted therapies has recently become possible and appears to be promising. This article focuses on anti-Her-2 therapy, specifically trastuzumab, as well as other epidermal growth factor receptor antagonists such as cetuximab, panitumub, matuzumab, nimotzumab, gefitinib, and erlotinib. Additionally, drugs that target angiogenesis pathways are also under investigation, particulary bevacizumab, ramucirumab, sorafenib, sunitinib, and cediranib. Other targeted agents in preclinical or early clinical development include mTOR inhibitors, anti c-MET, polo-like kinase 1 inhibitors, anti-insulin-like growth factor, anti-heat shock proteins, and small molecules targeting Hedgehog signaling.
2.A phase I pharmacokinetic study of matuzumab in combination with paclitaxel in patients with EGFR-expressing advanced non-small cell lung cancer.

Matuzumab is a humanized IgG1 EGFR monoclonal antibody. This phase I study investigated the tolerability, safety and pharmacokinetics (PK) of matuzumab in combination with paclitaxel in patients with EGFR-expressing advanced non-small cell lung cancer (NSCLC). Six dose levels/schedules of matuzumab were explored in combination with paclitaxel. Dose was escalated from 100 mg to 1,600 mg on a modified Fibonacci scheme according to the incidence of dose-limiting toxicity (DLT) over the first two cycles. DLT was assessed in patients who completed the first two treatment cycles or who stopped treatment because of a DLT during those cycles. Patients with non-progressive disease could then continue to receive study treatment for up to 6 months. The safety population comprised 44 patients, with DLT evaluable in 33. The maximum tolerated dose was not reached, with only one DLT reported at the 1,600 mg 3-weekly dose level. The most frequent grade 3/4 adverse events across all cycles were dyspnea (23 %) and neutropenia (11 %).
3.²¹³Bi-anti-EGFR radioimmunoconjugates and X-ray irradiation trigger different cell death pathways in squamous cell carcinoma cells.
Pickhard A1, Piontek G, Seidl C, Kopping S, Blechert B, Mißlbeck M, Brockhoff G, Bruchertseifer F, Morgenstern A, Essler M. Nucl Med Biol. 2014 Jan;41(1):68-76. doi: 10.1016/j.nucmedbio.2013.09.010. Epub 2013 Oct 9.
INTRODUCTION: Treatment of patients with squamous cell carcinoma of head and neck is hampered by resistance of tumor cells to irradiation. Additional therapies enhancing the effect of X-ray irradiation may be beneficial. Antibodies targeting EGFR have been shown to improve the efficacy of radiation therapy. Therefore, we analyzed cytotoxicity of (213)Bi-anti-EGFR immunoconjugates in combination with X-ray irradiation.
4.Alpha-particle emitting 213Bi-anti-EGFR immunoconjugates eradicate tumor cells independent of oxygenation.
Wulbrand C1, Seidl C, Gaertner FC, Bruchertseifer F, Morgenstern A, Essler M, Senekowitsch-Schmidtke R. PLoS One. 2013 May 28;8(5):e64730. doi: 10.1371/journal.pone.0064730. Print 2013.
Hypoxia is a central problem in tumor treatment because hypoxic cells are less sensitive to chemo- and radiotherapy than normoxic cells. Radioresistance of hypoxic tumor cells is due to reduced sensitivity towards low Linear Energy Transfer (LET) radiation. High LET α-emitters are thought to eradicate tumor cells independent of cellular oxygenation. Therefore, the aim of this study was to demonstrate that cell-bound α-particle emitting (213)Bi immunoconjugates kill hypoxic and normoxic CAL33 tumor cells with identical efficiency. For that purpose CAL33 cells were incubated with (213)Bi-anti-EGFR-MAb or irradiated with photons with a nominal energy of 6 MeV both under hypoxic and normoxic conditions. Oxygenation of cells was checked via the hypoxia-associated marker HIF-1α. Survival of cells was analysed using the clonogenic assay. Cell viability was monitored with the WST colorimetric assay. Results were evaluated statistically using a t-test and a Generalized Linear Mixed Model (GLMM).
