Strategies to Enhance Monoclonal Antibody Uptake and Distribution in Solid Tumors
Cancer Biol Med 2021. doi: 10.20892/j.issn.2095-3941.2020.0704 REVIEW Strategies to enhance monoclonal antibody uptake and distribution in solid tumors Brandon M. Bordeau, Joseph P. Balthasar Department of Pharmaceutical Science, University at Buffalo, Buffalo, NY 14214, USA ABSTRACT Despite the significant resources dedicated to the development of monoclonal antibody (mAb) therapies for solid tumors, the clinical success, thus far, has been modest. Limited efficacy of mAb in solid tumors likely relates to unique aspects of tumor physiology. Solid tumors have an aberrant vasculature and a dense extracellular matrix that slow both the convective and diffusive transport of mAbs into and within tumors. For mAbs that are directed against cellular antigens, high antigen expression and rapid antigen turnover can result in perivascular cells binding to and eliminating a significant amount of extravasated mAb, limiting mAb distribution to portions of the tumor that are distant from functional vessels. Many preclinical investigations have reported strategies to improve mAb uptake and distribution; however, to our knowledge, none have translated into the clinic. Here, we provide an overview of several barriers in solid tumors that limit mAb uptake and distribution and discuss approaches that have been utilized to overcome these barriers in preclinical studies. KEYWORDS Solid tumors; antibody uptake and distribution; monoclonal antibody; antibody–drug conjugate Introduction Currently, monoclonal antibodies (mAbs) are heralded as the “magic bullets” that Ehrlich envisioned, and in many cases, the In 1900, Paul Ehrlich developed the receptor theory, which moniker is well deserved. Antibodies can bind most substances was built on the foundational hypothesis that toxins, nutri- with high affinity and high selectivity and are used for the treat- ents, and drugs exert their observed effect through binding to ment of many diseases. -
Predictive QSAR Tools to Aid in Early Process Development of Monoclonal Antibodies
Predictive QSAR tools to aid in early process development of monoclonal antibodies John Micael Andreas Karlberg Published work submitted to Newcastle University for the degree of Doctor of Philosophy in the School of Engineering November 2019 Abstract Monoclonal antibodies (mAbs) have become one of the fastest growing markets for diagnostic and therapeutic treatments over the last 30 years with a global sales revenue around $89 billion reported in 2017. A popular framework widely used in pharmaceutical industries for designing manufacturing processes for mAbs is Quality by Design (QbD) due to providing a structured and systematic approach in investigation and screening process parameters that might influence the product quality. However, due to the large number of product quality attributes (CQAs) and process parameters that exist in an mAb process platform, extensive investigation is needed to characterise their impact on the product quality which makes the process development costly and time consuming. There is thus an urgent need for methods and tools that can be used for early risk-based selection of critical product properties and process factors to reduce the number of potential factors that have to be investigated, thereby aiding in speeding up the process development and reduce costs. In this study, a framework for predictive model development based on Quantitative Structure- Activity Relationship (QSAR) modelling was developed to link structural features and properties of mAbs to Hydrophobic Interaction Chromatography (HIC) retention times and expressed mAb yield from HEK cells. Model development was based on a structured approach for incremental model refinement and evaluation that aided in increasing model performance until becoming acceptable in accordance to the OECD guidelines for QSAR models. -

Rodriguez Copy Editor: Cui Yu Production Editor: Huan-Liang Wu Abstract Gastrointestinal (GI) cancers represent the leading cause of cancer-related mortality worldwide. Antibody drug conjugates (ADCs) are a rapidly growing new class of anti-cancer agents which may improve GI cancer patient survival. ADCs combine tumour-antigen specific antibodies with cytotoxic drugs to deliver tumour cell specific chemotherapy. Currently, only two ADCs [brentuximab vedotin and trastuzumab emtansine (T-DM1)] have been Food and Drug Administration approved for the treatment of lymphoma and metastatic breast cancer, respectively. Clinical research evaluating ADCs in GI cancers has shown limited success. In this review, we will retrace the relevant clinical trials investigating ADCs in GI cancers, especially ADCs targeting human epidermal growth receptor 2, mesothelin, guanylyl cyclase C, carcinogenic antigen-related cell adhesion molecule 5 (also known as CEACAM5) and other GI malignancy specific targets. -
Immunotherapy in Various Cancers
© 2021 JETIR June 2021, Volume 8, Issue 6 www.jetir.org (ISSN-2349-5162) Immunotherapy in various Cancers Nirav Parmar 1st Year MSc Student Department of Biosciences and Bioengineering, IIT- Roorkee India Abstract: Immunotherapy in the metastatic situation has changed the therapeutic landscape for a variety of cancers, including colorectal cancer. Immunotherapy has firmly established itself as a new pillar of cancer treatment in a variety of cancer types, from the metastatic stage to adjuvant and neoadjuvant settings. Immune checkpoint inhibitors have risen to prominence as a treatment option based on a better knowledge of the development of the tumour microenvironment immune cell-cancer cell regulation over time. Immunotherapy has lately appeared as the most potential field of cancer research by increasing effectiveness and reducing side effects, with FDA-approved therapies for more than 10 various tumours and thousands of new clinical studies. Key Words: Immunotherapy, metastasis, immune checkpoint. Introduction: In the late 1800s, William B. Coley, now generally regarded as the founder of immunotherapy, tried to harness the ability of immune system to cure cancer for the first time. Coley began injecting live and attenuated bacteria like Streptococcus pyogenes and Serratia marcescens into over a thousand patients in 1891 in the hopes of causing sepsis and significant immunological and antitumor responses. His bacterium mixture became known as "Coley's toxin" and is the first recorded active cancer immunotherapy treatment [1]. To better understand the processes of new and traditional immunological targets, the relationship between the immune system and tumour cells should be examined. Tumours have developed ways to evade immunological responses. -
Deciphering Molecular Mechanisms and Prioritizing Therapeutic Targets in Cardio-Oncology
Figure 1. This is a pilot view to explore the potential of EpiGraphDB to inform us about proteins that are linked to the pathophysiology of cancer and cardiovascular disease (CVD). For each cancer type (pink diamonds), we searched for cancer related proteins (light blue circles) that interact with other proteins identified as protein quantitative trait loci (pQTLs) for CVD (red diamonds for pathologies, orange triangles for risk factors). These pQTLs can be acting in cis (solid lines) or trans-acting (dotted lines). Proteins can interact either directly, a protein-protein interaction (dotted blue edges), or through the participation in the same pathway (red parallel lines). Shared pathways are represented with blue hexagons. We also queried which of these proteins are targeted by existing drugs. We found that the cancer drug cetuximab (yellow circle) inhibits EGFR. Other potential drugs are depicted in light brown hexagonal meta-nodes that are detailed below.

This has led to the development of several therapeutic strategies focused in this direction. However, a high percentage of lung cancer patients do not respond to these therapies or their responses are transient. Here, we summarized the impact of immunotherapy on lung cancer patients in the latest clinical trials conducted on this disease. As well as the mechanisms of primary and acquired resistance to immunotherapy in this disease. Abstract: After several decades without maintained responses or long-term survival of patients with lung cancer, novel therapies have emerged as a hopeful milestone in this research field. -
