[PMID: 37804358 DOI: 10.1007/s10238-023-01201-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Accepted: 09/19/2023] [Indexed: 10/09/2023]
Abstract
Through improving the immune system's ability to recognize and combat tumor cells as well as its receptivity to changes in the tumor microenvironment, immunotherapy has emerged as a highly successful addition to the treatment of cancer. However, tumor heterogeneity poses a significant challenge in cancer therapy as it can undermine the anti-tumor immune response through the manipulation of the extracellular matrix. To address these challenges and improve targeted therapies and combination treatments, the food and drug administration has approved several immunomodulatory antibodies to suppress immunological checkpoints. Combinatorial therapies necessitate the identification of multiple targets that regulate the intricate communication between immune cells, cytokines, chemokines, and cellular responses within the tumor microenvironment. The purpose of this study is to provide a comprehensive overview of the ongoing clinical trials involving immunomodulatory antibodies in various cancer types. It explores the potential of these antibodies to modulate the immune system and enhance anti-tumor responses. Additionally, it discusses the perspectives and prospects of immunomodulatory therapeutics in cancer treatment. Although immunotherapy shows great promise in cancer treatment, it is not exempt from side effects that can arise due to hyperactivity of the immune system. Therefore, understanding the intricate balance between immune activation and regulation is crucial for minimizing these adverse effects and optimizing treatment outcomes. This study aims to contribute to the growing body of knowledge surrounding immunomodulatory antibodies and their potential as effective therapeutic options in cancer treatment, ultimately paving the way for improved patient outcomes and deepening our perception of the intricate interactivity between the immune system and tumors.

Fantini M, Arlen PM, Tsang KY. Potentiation of natural killer cells to overcome cancer resistance to NK cell-based therapy and to enhance antibody-based immunotherapy. Front Immunol 2023; 14:1275904. [PMID: 38077389 PMCID: PMC10704476 DOI: 10.3389/fimmu.2023.1275904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Accepted: 10/23/2023] [Indexed: 12/18/2023] Open
Abstract
Natural killer (NK) cells are cellular components of the innate immune system that can recognize and suppress the proliferation of cancer cells. NK cells can eliminate cancer cells through direct lysis, by secreting perforin and granzymes, or through antibody-dependent cell-mediated cytotoxicity (ADCC). ADCC involves the binding of the Fc gamma receptor IIIa (CD16), present on NK cells, to the constant region of an antibody already bound to cancer cells. Cancer cells use several mechanisms to evade antitumor activity of NK cells, including the accumulation of inhibitory cytokines, recruitment and expansion of immune suppressor cells such as myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Tregs), modulation of ligands for NK cells receptors. Several strategies have been developed to enhance the antitumor activity of NK cells with the goal of overcoming cancer cells resistance to NK cells. The three main strategies to engineer and boost NK cells cytotoxicity include boosting NK cells with modulatory cytokines, adoptive NK cell therapy, and the employment of engineered NK cells to enhance antibody-based immunotherapy. Although the first two strategies improved the efficacy of NK cell-based therapy, there are still some limitations, including immune-related adverse events, induction of immune-suppressive cells and further cancer resistance to NK cell killing. One strategy to overcome these issues is the combination of monoclonal antibodies (mAbs) that mediate ADCC and engineered NK cells with potentiated anti-cancer activity. The advantage of using mAbs with ADCC activity is that they can activate NK cells, but also favor the accumulation of immune effector cells to the tumor microenvironment (TME). Several clinical trials reported that combining engineered NK cells with mAbs with ADCC activity can result in a superior clinical response compared to mAbs alone. Next generation of clinical trials, employing engineered NK cells with mAbs with higher affinity for CD16 expressed on NK cells, will provide more effective and higher-quality treatments to cancer patients.

Abstract
BACKGROUND Collecting duct carcinoma (CDC) of the kidney is associated with an aggressive course, limited response to treatment, and poor prognosis. Platinum-based chemotherapy is currently recommended as the first-line treatment in patients with metastatic CDC. Accumulating evidence supports the use of immunotherapy with checkpoint inhibitors as second-line therapy. CASE PRESENTATION In this case report, we describe the first case of avelumab administration due to disease progression during chemotherapy with gemcitabine and cisplatin in a Caucasian, 71-year-old man presenting with multiple metastases due to CDC of the kidney. The patient initially responded well to four cycles of chemotherapy and his performance status improved. After two additional chemotherapy cycles, the patient presented with new bone and liver metastases (mixed response to chemotherapy with an overall 6-month progression-free survival). We offered him avelumab as a second-line treatment in this setting. The patient received a total of three cycles of avelumab. The disease remained stable (no new metastases during treatment with avelumab), and the patient developed no complications. To alleviate his symptoms, radiation therapy for the bone metastases was decided. Despite successful radiation of the bone lesions and further improvement of symptoms, the patient developed hospital-acquired pneumonia and died approximately ten months after the initial diagnosis of CDC. CONCLUSIONS Our findings suggest that the applied treatment modality with gemcitabine and cisplatin chemotherapy followed by avelumab was effective in terms of both progression-free survival and quality of life. Still, further studies assessing the use of avelumab in this setting are mandatory.

Abstract
Antibodies as ideal therapeutic and diagnostic molecules are among the top-selling drugs providing considerable efficacy in disease treatment, especially in cancer therapy. Limitations of the hybridoma technology as routine antibody generation method in conjunction with numerous developments in molecular biology led to the development of alternative approaches for the streamlined identification of most effective antibodies. In this regard, display selection technologies such as phage display, bacterial display, and yeast display have been widely promoted over the past three decades as ideal alternatives to traditional methods. The display of antibodies on phages is probably the most widespread of these methods, although surface display on bacteria or yeast have been employed successfully, as well. These methods using various sizes of combinatorial antibody libraries and different selection strategies possessing benefits in screening potency, generating, and isolation of high affinity antibodies with low risk of immunogenicity. Knowing the basics of each method assists in the design and retrieval process of antibodies suitable for different diseases, including cancer. In this review, we aim to outline the basics of each library construction and its display method, screening and selection steps. The advantages and disadvantages in comparison to alternative methods, and their applications in antibody engineering will be explained. Finally, we will review approved or non-approved therapeutic antibodies developed by employing these methods, which may serve as therapeutic antibodies in cancer therapy.

Abstract
Avelumab can kill cancer cells through immune checkpoint inhibition and antibody-dependent cell-mediated cytotoxicity (ADCC). Here, we analyzed the clinical efficacy and adverse events (AEs) in 3935 cancer patients from 21 trials. Compared with conventional treatment, avelumab monotherapy was associated with more tumor responses and less AEs. The pooled objective response rate was 14.18 % (95 % CI, 10.68 %-18.08 %). More PD-L1 positive patients responded to avelumab monotherapy compared to PD-L1 negative patients. The overall incidence was 73.78 % for all-grade treatment-related AE (TRAE), 14.44 % for high-grade TRAE, 6.07 % for serious adverse event, 0.44 % for fatal adverse event, 17.86 % for all-grade immune-related AE (irAE), and 3.22 % for high-grade irAE. In summary, avelumab monotherapy presents an active anti-tumor activity, shows no sign of increased toxicity due to the ADCC. These characteristics provide rational for further application of avelumab in cancer treatment.

Abstract
PD-L1 and ICOS are immune control points in cancer and their presence in cancer tends to have a poor prognosis. WO2019122882 patent describes a bispecific antibody that targets PDL-1/ICOS with the potential application of cancer treatment. WO2019122882 patent describes a bispecific antibody with antitumor efficacy in CT26 model through of the depletion of TReg cells and improved ratio of CD8+ T cells: TReg in tumor microenvironment. The anti-PDL-1/ICOS antibody is new; however, only preclinical assays are shown using colon carcinoma model. So far, there are no reports of clinical trials to evaluate the safety, toxicity and efficacy, but it will be of great interest to analyze in the future if this antibody surpasses the action of the combinatorial therapy in cancer.

Abstract
It has been more than three decades since the first monoclonal antibody was approved by the United States Food and Drug Administration (US FDA) in 1986, and during this time, antibody engineering has dramatically evolved. Current antibody drugs have increasingly fewer adverse effects due to their high specificity. As a result, therapeutic antibodies have become the predominant class of new drugs developed in recent years. Over the past five years, antibodies have become the best-selling drugs in the pharmaceutical market, and in 2018, eight of the top ten bestselling drugs worldwide were biologics. The global therapeutic monoclonal antibody market was valued at approximately US$115.2 billion in 2018 and is expected to generate revenue of $150 billion by the end of 2019 and $300 billion by 2025. Thus, the market for therapeutic antibody drugs has experienced explosive growth as new drugs have been approved for treating various human diseases, including many cancers, autoimmune, metabolic and infectious diseases. As of December 2019, 79 therapeutic mAbs have been approved by the US FDA, but there is still significant growth potential. This review summarizes the latest market trends and outlines the preeminent antibody engineering technologies used in the development of therapeutic antibody drugs, such as humanization of monoclonal antibodies, phage display, the human antibody mouse, single B cell antibody technology, and affinity maturation. Finally, future applications and perspectives are also discussed.
