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. -
The Role of Biological Therapy in Metastatic Colorectal Cancer After First-Line Treatment: a Meta-Analysis of Randomised Trials
REVIEW British Journal of Cancer (2014) 111, 1122–1131 | doi: 10.1038/bjc.2014.404 Keywords: colorectal; biological; meta-analysis The role of biological therapy in metastatic colorectal cancer after first-line treatment: a meta-analysis of randomised trials E Segelov1, D Chan*,2, J Shapiro3, T J Price4, C S Karapetis5, N C Tebbutt6 and N Pavlakis2 1St Vincent’s Clinical School, University of New South Wales, Sydney, NSW 2052, Australia; 2Royal North Shore Hospital, St Leonards, Sydney, NSW 2065, Australia; 3Monash University and Cabrini Hospital, Melbourne, VIC 3800, Australia; 4The Queen Elizabeth Hospital and University of Adelaide, Woodville South, SA 5011, Australia; 5Flinders University and Flinders Medical Centre, Flinders Centre for Innovation in Cancer, Bedford Park, SA, 5042, Australia and 6Austin Health, VIC 3084, Australia Purpose: Biologic agents have achieved variable results in relapsed metastatic colorectal cancer (mCRC). Systematic meta-analysis was undertaken to determine the efficacy of biological therapy. Methods: Major databases were searched for randomised studies of mCRC after first-line treatment comparing (1) standard treatment plus biologic agent with standard treatment or (2) standard treatment with biologic agent with the same treatment with different biologic agent(s). Data were extracted on study design, participants, interventions and outcomes. Study quality was assessed using the MERGE criteria. Comparable data were pooled for meta-analysis. Results: Twenty eligible studies with 8225 patients were identified. The use of any biologic therapy improved overall survival with hazard ratio (HR) 0.87 (95% confidence interval (CI) 0.82–0.91, Po0.00001), progression-free survival (PFS) with HR 0.71 (95% CI 0.67–0.74, Po0.0001) and overall response rate (ORR) with odds ratio (OR) 2.38 (95% CI 2.03–2.78, Po0.00001). -

Sandhu, MD3, Anthony Tolcher, MD4, Hugh M. Davis, PhD2, Honghui Zhou, PhD, FCP2, and Thomas A. Puchalski, PharmD2 Abstract The chemokine ligand 2 (CCL2) promotes angiogenesis, tumor proliferation, migration, and metastasis. Carlumab is a human IgG1k monoclonal antibody with high CCL2 binding affinity. Pharmacokinetic/pharmacodynamic data from 21 cancer patients with refractory tumors were analyzed. The PK/PD model characterized the temporal relationships between serum concentrations of carlumab, free CCL2, and the carlumab–CCL2 complex. Dose‐dependent increases in total CCL2 concentrations were observed and were consistent with shifting free CCL2. Free CCL2 declined rapidly after the initial carlumab infusion, returned to baseline within 7 days, and increased to levels greater than baseline following subsequent doses. Mean predicted half‐lives of carlumab and carlumab–CCL2 complex were approximately 2.4 days and approximately 1 hour for free CCL2. The mean dissociation constant (KD), 2.4 nM, was substantially higher than predicted by in vitro experiments, -
Targeted and Novel Therapy in Advanced Gastric Cancer Julie H
Selim et al. Exp Hematol Oncol (2019) 8:25 https://doi.org/10.1186/s40164-019-0149-6 Experimental Hematology & Oncology REVIEW Open Access Targeted and novel therapy in advanced gastric cancer Julie H. Selim1 , Shagufta Shaheen2 , Wei‑Chun Sheu3 and Chung‑Tsen Hsueh4* Abstract The systemic treatment options for advanced gastric cancer (GC) have evolved rapidly in recent years. We have reviewed the recent data of clinical trial incorporating targeted agents, including inhibitors of angiogenesis, human epidermal growth factor receptor 2 (HER2), mesenchymal–epithelial transition, epidermal growth factor receptor, mammalian target of rapamycin, claudin‑18.2, programmed death‑1 and DNA. Addition of trastuzumab to platinum‑ based chemotherapy has become standard of care as front‑line therapy in advanced GC overexpressing HER2. In the second‑line setting, ramucirumab with paclitaxel signifcantly improves overall survival compared to paclitaxel alone. For patients with refractory disease, apatinib, nivolumab, ramucirumab and TAS‑102 have demonstrated single‑agent activity with improved overall survival compared to placebo alone. Pembrolizumab has demonstrated more than 50% response rate in microsatellite instability‑high tumors, 15% response rate in tumors expressing programmed death ligand 1, and non‑inferior outcome in frst‑line treatment compared to chemotherapy. This review summarizes the current state and progress of research on targeted therapy for advanced GC.

Cooling, J. Sherbeck, J.C. Mowers, and S.L. Hugan Ipilimumab, nivolumab, and pembrolizumab represent a new Table 1. Checkpoint inhibitors class of immunotherapeutic drugs for treating patients with Drug class (trade name, manufacturer) advanced cancer. Known as checkpoint inhibitors, these drugs act to upregulate the cellular and humoral immune response Anti-CTLA-4 to tumor antigens by inhibiting T-cell autoregulation. As a Ipilimumab (Yervoy, Bristol-Myers Squibb) consequence, they can be associated with immune-related adverse Tremelimumab (AstraZeneca, compassionate use only) events (irAEs) due to loss of self-tolerance, including rare cases of immune-related cytopenias. We performed a retrospective Anti-PD-1 clinical chart review, including serologic, hematology, and Nivolumab (Opdivo, Bristol-Myers Squibb) chemistry laboratory results, of two patients who developed Pembrolizumab (Keytruda, Merck Sharp & Dohme) red blood cell (RBC) autoantibodies during treatment with a Pidilizumab (Medivations, in clinical trials) checkpoint inhibitor. Serologic testing of blood samples from these patients during induction therapy with ipilimumab and Anti-PD-L1 nivolumab, respectively, showed their RBCs to be positive by Atezolizumab (Genentech, in clinical trials) the direct antiglobulin test (IgG+, C3+) and their plasma to Durvalumab (AstraZeneca, approved bladder cancer) contain panreactive RBC autoantibodies. Neither patient had evidence of hemolysis. Both patients developed an additional CTLA-4 = cytotoxic T-lymphocyte–associated antigen 4; PD-1 = programmed cell death protein 1; PD-L1 = programmed cell death ligand 1. -

Therapeutic Targeting of the IGF Axis
cells Review Therapeutic Targeting of the IGF Axis Eliot Osher and Valentine M. Macaulay * Department of Oncology, University of Oxford, Oxford, OX3 7DQ, UK * Correspondence: [email protected]; Tel.: +44-1865617337 Received: 8 July 2019; Accepted: 9 August 2019; Published: 14 August 2019 Abstract: The insulin like growth factor (IGF) axis plays a fundamental role in normal growth and development, and when deregulated makes an important contribution to disease. Here, we review the functions mediated by ligand-induced IGF axis activation, and discuss the evidence for the involvement of IGF signaling in the pathogenesis of cancer, endocrine disorders including acromegaly, diabetes and thyroid eye disease, skin diseases such as acne and psoriasis, and the frailty that accompanies aging. We discuss the use of IGF axis inhibitors, focusing on the different approaches that have been taken to develop effective and tolerable ways to block this important signaling pathway. We outline the advantages and disadvantages of each approach, and discuss progress in evaluating these agents, including factors that contributed to the failure of many of these novel therapeutics in early phase cancer trials. Finally, we summarize grounds for cautious optimism for ongoing and future studies of IGF blockade in cancer and non-malignant disorders including thyroid eye disease and aging. Keywords: IGF; type 1 IGF receptor; IGF-1R; cancer; acromegaly; ophthalmopathy; IGF inhibitor 1. Introduction Insulin like growth factors (IGFs) are small (~7.5 kDa) ligands that play a critical role in many biological processes including proliferation and protection from apoptosis and normal somatic growth and development [1]. IGFs are members of a ligand family that includes insulin, a dipeptide comprised of A and B chains linked via two disulfide bonds, with a third disulfide linkage within the A chain. -
