Nimotuzumab is a humanized IgG1 monoclonal antibody targeting EGFR with a KD of 0.21 nM. Nimotuzumab is directed against the extracellular domain of the EGFR blocking the binding to its ligands. Nimotuzumab, a strong antitumor drug, is cytolytic on target tumors by its capacity to cause antibody dependent cell mediated cytotoxicity (ADCC) and complement dependent cytotoxicity (CDC)[1][2].
Nimotuzumab (10 μg/mL; 24 hours) induces significant downregulation of CD16 on NK cells[1]. Nimotuzumab (10 μg/mL; 48 hours) induces the upregulation of PD-L1 molecule on DCs when co-cultured with the NK: DC: HNSCC cells[1]. The intrinsic properties of Nimotuzumab requires bivalent binding (i.e., binding with both antibody arms to two targets simultaneously) for stable attachment to cellular surface, which leads to Nimotuzumab selectively binding to cells that express moderate to high EGFR levels[2].

Nimotuzumab, an Anti-EGFR Monoclonal Antibody, in the Treatment of Nasopharyngeal Carcinoma
Cancer Control 2021 Jan-Dec;28:1073274821989301.PMID:33504193DOI:10.1177/1073274821989301.
Epidermal growth factor receptor (EGFR) is highly expressed in most of Nasopharyngeal carcinoma (NPC) samples and is associated with poor outcomes. Therefore, targeting EGFR may be a promising strategy to improve patient prognosis. Nimotuzumab is a humanized anti-EGFR monoclonal antibody. Recently, accumulating evidence has demonstrated that combination Nimotuzumab and induction chemotherapy, radiotherapy, or concurrent chemoradiotherapy confer benefits for patients with NPC. Moreover, the side effects of such regimes are tolerable. In this review, we focus on the current data of Nimotuzumab in clinical trials in the treatment of NPC.
Nimotuzumab for Patients With Inoperable Cancer of the Head and Neck
Front Oncol 2020 May 27;10:817.PMID:32537431DOI:10.3389/fonc.2020.00817.
EGFR activation induces cell proliferation, neoformation of blood vessels, survival, and metastasis of the cancer cells. Nimotuzumab is an engineered, intermediate affinity anti-EGFR antibody, that apart from other drugs in its class, is very safe and does not cause hypomagnesemia or grade 3-4 cutaneous rash. The antibody inhibits cell proliferation and angiogenesis, activates natural killer cells, stimulates dendritic cell maturation, and induces cytotoxic T cells. Nimotuzumab restores MHC-I expression on tumor cells, hindering one of the EGFR immune-escape ways. The antibody has been extensively studied in 7 clinical trials, concurrently with irradiation or irradiation plus chemotherapy in subjects with inoperable head and neck tumors. Nimotuzumab was safe and efficacious in unfit patients receiving irradiation alone and in subjects treated with cisplatin and radiotherapy. In patients with locally advanced squamous cell carcinomas of the head and neck, Nimotuzumab in combination with low dose cisplatin and radiotherapy was superior to cisplatin and radiotherapy in progression free survival, disease free survival, and locoregional tumor control.
Nimotuzumab combined with chemoradiotherapy for the treatment of cervical cancer: A meta-analysis of randomized controlled trials
Front Oncol 2022 Oct 3;12:994726.PMID:36263226DOI:10.3389/fonc.2022.994726.
Objectives: To assess the clinical efficacy and toxicity of Nimotuzumab in combination with chemoradiotherapy or chemoradiotherapy alone in the treatment of cervical cancer. Methods: The PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, China Biomedical Medicine, Wanfang, and VIP databases were systematically searched for relevant literature. Ultimately, six randomised controlled trials (n=393) were included in our meta-analysis. Results: A total of 393 patients were included, of which 197 were in the Nimotuzumab combined with chemoradiotherapy group and 196 were in the chemoradiotherapy group. The results of our meta-analysis showed that the complete remission rate (risk ratio [RR] = 1.34, 95% confidence interval [CI]: 1.08-1.65, P = 0.007), objective response rate (RR = 1.30, 95% CI: 1.16-1.44, P < 0.05), and three-year survival rate (RR = 1.27, 95% CI: 1.06-1.51, P = 0.008) in the Nimotuzumab combined with chemoradiotherapy group were significantly improved compared with the chemoradiotherapy group. This difference was not statistically significant when comparing the incidence of adverse reactions (such as leukocytopenia, gastrointestinal reaction, radiocystitis, and radioproctitis) between the two groups. Conclusions: Nimotuzumab in combination with chemoradiotherapy has some advantages over chemoradiotherapy alone in the treatment of cervical cancer and does not increase toxicity. Therefore, Nimotuzumab has the potential to be an effective treatment for cervical cancer; however, further evidence from large-scale randomised controlled trials is needed.
A randomized phase 3 trial comparing Nimotuzumab plus cisplatin chemoradiotherapy versus cisplatin chemoradiotherapy alone in locally advanced head and neck cancer
Cancer 2019 Sep 15;125(18):3184-3197.PMID:31150120DOI:10.1002/cncr.32179.
Background: Because the addition of Nimotuzumab to chemoradiation in patients with locally advanced head and neck cancer improved outcomes in a phase 2 study, the authors conducted a phase 3 study to confirm these findings. Methods: This open-label, investigator-initiated, phase 3, randomized trial was conducted from 2012 to 2018. Adult patients with locally advanced head and neck cancer who were fit for radical chemoradiation were randomized 1:1 to receive either radical radiotherapy (66-70 grays) with concurrent weekly cisplatin (30 mg/m2 ) (CRT) or the same schedule of CRT with weekly Nimotuzumab (200 mg) (NCRT).The primary endpoint was progression-free survival (PFS); key secondary endpoints were disease-free survival (DFS), duration of locoregional control (LRC), and overall survival (OS). An intent-to-treat analysis also was performed. Results: In total, 536 patients were allocated equally to both treatment arms. The median follow-up was 39.13 months. The addition of Nimotuzumab improved PFS (hazard ratio [HR], 0.69; 95% CI, 0.53-0.89; P = .004), LRC (HR, 0.67; 95% CI, 0.50-0.89; P = .006), and DFS (HR, 0.71; 95% CI, 0.55-0.92; P = .008) and had a trend toward improved OS (HR, 0.84; 95% CI, 0.65-1.08; P = .163). Grade 3 through 5 adverse events were similar between the 2 arms, except for a higher incidence of mucositis in the NCRT arm (66.7% vs 55.8%; P = .01). Conclusions: The addition of Nimotuzumab to concurrent weekly CRT improves PFS, LRC, and DFS. This combination provides a novel alternative therapeutic option to a 3-weekly schedule of 100 mg/m2 cisplatin in patients with locally advanced head and neck cancer who are treated with radical-intent CRT.
Nimotuzumab: beyond the EGFR signaling cascade inhibition
Semin Oncol 2018 Jan;45(1-2):18-26.PMID:30318080DOI:10.1053/j.seminoncol.2018.04.008.
One of the most known oncogenes is the epidermal growth factor receptor (EGFR) family. It activates multiple signaling cascades that promote carcinogenesis and immune evasion. Therefore, these molecules have been extensively targeted in cancer immunotherapy. Beyond EGFR signaling cascade inhibition, some of these agents are able to induce T-cell activation, transforming a passive therapy into a vaccine-like effect. Nimotuzumab is an IgG1 humanized monoclonal antibody directed against the extracellular domain of the EGFR blocking the binding to its ligands. It possesses unique pharmacodynamic properties, which allow treating patients for long-term periods and with very low toxicity. Based on its clinical effect, Nimotuzumab has been approved in Cuba and abroad for the treatment of different epithelial tumors. Recently, new potential mechanisms of action of Nimotuzumab involving the activation of the innate and adaptive immune response have been reported. This review summarizes the main properties of Nimotuzumab in comparison with other EGFR-specific monoclonal antibodies, highlighting its capacity to activate an effective immune response. In addition, differential clinical effects of this antibody and ongoing clinical trials to deeply characterize the biomarkers of clinical benefit are shown.
