A previous small study tested an anti-HER2 DC-based vaccine in the adjuvant setting for 7 women with high risk invasive HER2+ (IHC2+ to 3+/FISH+) BC, which had undergone standard treatment (± trastuzumab). Treatment was safe and elicited anti-HER2 specific immune response [186]. Ding LW, Sun QY, Edwards JJ, Fernández LT, Ran XB, Zhou SQ, et al.

In these same set of patients, the combination of atezolizumab with nab-paclitaxel yielded also an OS advantage in the phase III trial Impassion 130, [144], while the anti-PD1 pembrolizumab in association with standard neoadjuvant chemotherapy raised the pCR rate to 60% and 80% in two different studies [145, 146].

It is being tested in phase I trials for HER2+ solid tumors including breast cancer as a monotherapy [96]. 2013;14(6):461–71. Although the first steps have been taken with immunotherapy in breast cancer, Sherene Loi, MBBS, FRACP, PhD, FAHMS, said development is still lagging in HER2-positive disease because of … J Immunother Cancer. 2016;375(9):819–29. 2011;459(3):283–9. A cancer-selective oncolytic adenovirus was engineered to encode trastuzumab antibody chains allowing the production of monoclonal anti-HER2 antibody directly by cancer cells, which are then lysed, releasing both new virions and the Tumor-associated antigens (TAAs) for dendritic cells (DC) recognition and activation. 2016;146(4):496–502. The effective development of this therapeutical approach has become possible mainly thanks to the advent of next-generation sequencing (NGS), which is associated to dedicated bioinformatic tools in order to build a comprehensive map of tumor mutations (mutanome) and a reliable prediction of epitope-binding to MHC molecules. 2017;140(4):938–47. Moreover, clinical trials suggest higher efficacy if the treatment is given upfront, while a concomitant HER2 block is applied. All the aforementioned strategies should be conceptualized dynamically and functionally inside the larger blueprint of rapidly developing cancer treatment paraphernalia, embodying further immune modulating tactics or therapies which act on a gradually expanding core of cancer hallmarks. Colzani B, Pandolfi L, Hoti A, Iovene PA, Natalello A, Avvakumova S, et al. Tóth G, Szöőr Á, Simon L, Yarden Y, Szöllősi J, Vereb G. The combination of trastuzumab and pertuzumab administered at approved doses may delay development of trastuzumab resistance by additively enhancing antibody-dependent cell-mediated cytotoxicity. A further immunizing strategy was developed by using adoptive lymphocyte therapy using lymphocytes with tumoricidal potential [163]. 2013;23(6 Pt B):522–32. J Clin Oncol.

Improved survival of HER2+ breast cancer patients treated with trastuzumab and chemotherapy is associated with host antibody immunity against the HER2 intracellular domain. Disease-free survival (DFS) rates at 22 months were 85.7% and 59.8%, respectively (p = 0.19) [172].

However, some other interesting outcomes were reported. Rugo HS, Pegram MD, Gradishar WJ, Cortes J, Curigliano G, Wigginton JM, et al. Clin Cancer Res. This may translate into a higher potential to elicit anti-cancer response and, therefore, wider possibilities for the use and implementation of immunotherapy in this subset of BC patients. A pilot study evaluated the feasibility of treating HER2+ mBC patients refractory to previous therapies with radioimmunotherapy developed by attaching the radioactive lutetium-177 (Lu-177) to trastuzumab. Other studies suggest a possible advantage in terms of an increase in TILs and immune response when combining anti-HER2 therapy functionally and/or structurally with cytokines such as IL-2 or IFN-γ. This study showed that the treatment was feasible and safe and could be considered for palliative treatment of HER2+ mBC in combination with standard agents [132]. These associations could increase the magnitude of efficacy in a given HER2+ BC setting and/or extend the landscape of treatment applicability in terms of biological characteristics, such as anti-HER2 vaccine-based immunotherapy plus trastuzumab for HER2 IHC1+/2+ BC or anti-HER2 vaccines for HER2 IHC3+ DCIS; or expand treatment possibilities in terms of clinical setting, such as the use of anti-HER2 vaccines in the metastatic/neoadjuvant setting or immune checkpoint inhibition in the early disease.

The development of vaccines for the later phases of disease should consider the contemporary use of more antigens, while combining vaccination with additional anti-cancer treatment strategies such as immune checkpoint inhibitors, which have a strong rationale for clinical use not only in metastatic disease but whenever a macroscopic tumor is present, including the early and locally advanced phases. Tribody [(HER2)2xCD16] is more effective than trastuzumab in enhancing γδ T cell and natural killer cell cytotoxicity against HER2-expressing cancer cells. Butte MJ, Keir ME, Phamduy TB, Sharpe AH, Freeman GJ.

A paradigm shift in cancer immunotherapy: from enhancement to normalization. A nanobody activation immunotherapeutic that selectively destroys HER2-positive breast Cancer cells. Different phase I and phase II trials were conducted in the adjuvant setting, mostly for high-risk BC with any level of HER2 expression (IHC 1+ to 3+) using E75 vaccine plus GM-CSF, in patients who had completed standard treatment. However, anti-HER2 vaccines developed by engineering HER2+ BC cell lines failed to yield response in the metastatic setting. Moreover, as we could observe, a specific advantage of anti-HER2 vaccines for BC treatment is that they can yield clinical efficacy especially when HER2 protein presents an intermediate level of expression, which could extend the ground of action for an HER2-directed immunotherapeutic strategy.

The anti-PD-1/PD-L1 agents act at the effector stage by re-energizing pre-existing T cells, while anti-CTL-4 agents act at the proliferation/activation stage by also probably enhancing de novo responses. The third correlate, which is currently used as a predictive biomarker for immunotherapy in some tumors, is PD-L1 expression. Science. Cancer Res. Eur J Cancer. 2007;18(6):977–84.
