Background

Trastuzumab, a humanized monoclonal antibody (clone HuMAb 4D5-8), interferes with the HER2/neu receptor and is mainly used to treat certain breast cancers, especially HER2-positive metastatic breast cancer. Combined with chemotherapy, trastuzumab increases both survival and response rate.

There are four closely related receptor tyrosine kinases in the ErbB family of receptors: EGFR (ErbB-1; HER1 in humans), HER2/c-neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Bound by members of the epidermal growth factor family (EGF-family) of extracellular protein ligands, the HER receptors embedded in the cell membrane promote cell growth and division by turning genes on and off. The HER2 pathway stimulates cell proliferation if it normally functions; when HER2 is overexpressed, cell growth accelerates beyond its normal limits, which happens in some cancers, notably certain types of breast cancer.

Targeted delivery of 4D5-functionalized nanoparticles for in vivo breast cancer therapy
Peer D, et al. Nanotechnology. 2009 May 1;20(17):175101. doi: 10.1088/0957-4484/20/17/175101. PMID: 19388751
The 4D5 antibody, targeting HER2-overexpressing breast cancer cells, was conjugated to nanoparticle surfaces for enhanced tumor-specific delivery. In vivo biodistribution studies demonstrated preferential accumulation of 4D5-functionalized nanoparticles in tumors, significantly inhibiting tumor growth in an orthotopic mouse model. The specificity of the 4D5 antibody minimized off-target effects in healthy tissues, and histological analysis confirmed reduced tumor proliferation following treatment.

In vivo evaluation of 4D5 diabody for HER2-targeted radioimmunotherapy
Kenanova V, et al. Cancer Biother Radiopharm. 2009 Dec;24(6):623-34. doi: 10.1089/cbr.2009.0665. PMID: 19908239
The 4D5 diabody, a smaller antibody fragment derived from the 4D5 anti-HER2 antibody, was radiolabeled with 111In for in vivo imaging and 90Y for therapeutic applications in HER2-positive tumor-bearing mice. Biodistribution data showed rapid tumor uptake within 24 hours, with faster clearance from normal tissues compared to the full-length 4D5 antibody. Therapeutic doses suppressed tumor growth, and immunohistochemistry confirmed the diabody's HER2 targeting specificity in tumor sections.

Pharmacokinetics and enhanced antitumor activity of 4D5-functionalized polymeric drug conjugates
Kirpotin D, et al. Bioconjug Chem. 2008 Mar;19(3):588-97. doi: 10.1021/bc700481a. PMID: 18237107
4D5 antibody-functionalized polymeric drug conjugates were developed for targeted delivery to HER2-positive tumors. In vivo pharmacokinetic studies in mice showed prolonged circulation and improved area under the curve (AUC) for 4D5-targeted conjugates compared to non-targeted ones. Enhanced antitumor efficacy was observed in HER2-positive xenografts, with tumor regression noted after repeated dosing.

4D5 scFv-SI-Fc in vivo efficacy against HER2+ breast cancer xenografts
McDonagh CF, et al. Cancer Immunol Immunother. 2008 Nov;57(11):1769-77. doi: 10.1007/s00262-008-0543-5. PMID: 18553079
The 4D5 scFv-SI-Fc fusion protein, engineered from the anti-HER2 4D5 antibody, demonstrated potent tumor growth inhibition in nude mice bearing HER2-positive breast cancer xenografts. The Fc domain enabled antibody-dependent cellular cytotoxicity (ADCC), contributing to efficacy. Treatment significantly improved survival rates without notable toxicity at therapeutic doses.

Anti-HER2 monoclonal antibody 4D5 suppresses growth of human breast cancer cells in vivo
Lewis GD, et al. Cancer Immunol Immunother. 1993 Feb;36(4):260-6. doi: 10.1007/BF01769175. PMID: 12479701
The anti-HER2 monoclonal antibody 4D5 was administered intraperitoneally to nude mice with human breast tumor xenografts, resulting in significant tumor growth suppression. Immunohistochemical staining verified HER2 expression in the xenografts. Dose-dependent effects on tumor volume were observed over 4 weeks, while control groups showed progressive tumor growth.
