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. -
Viral Hepatitis Testing Effective Date: January 1, 2012
Viral Hepatitis Testing Effective Date: January 1, 2012 Scope This guideline provides guidance for the use of laboratory tests to diagnose acute and chronic viral hepatitis in adults (> 19 years) in the primary care setting. General Considerations for Ordering Laboratory Tests Prior to ordering tests for hepatitis, consider the patient’s history, age, risk factors (see below), hepatitis vaccination status, and any available previous hepatitis test results. Risk Factors for Viral Hepatitis include: • Substance use (includes sharing drug snorting, smoking or injection equipment) • High-risk sexual activity or sexual partner with viral hepatitis • Travel to or from high-risk hepatitis endemic areas or exposure during a local outbreak • Immigration from hepatitis B and/or C endemic countries • Household contact with an infected person especially if personal items (e.g., razors, toothbrushes, nail clippers) are shared • Recipient of unscreened blood products* • Needle-stick injury or other occupational exposure (e.g., healthcare workers) • Children born to mothers with chronic hepatitis B or C infection • Attendance at daycare • Contaminated food or water (hepatitis A only) • Tattoos and body piercing • History of incarceration • HIV or other sexually transmitted infection • Hemodialysis *screening of donated blood products for hepatitis C (anti-HCV) began in 1990 in Canada.1 Types of Viral Hepatitis Hepatitis A: causes acute but not chronic hepatitis Hepatitis B: causes acute and chronic hepatitis Hepatitis C: causes chronic hepatitis but rarely manifests as acute hepatitis Hepatitis D: rare and only occurs in patients infected with hepatitis B Hepatitis E: clinically similar to hepatitis A, mostly restricted to endemic areas and occasionally causes chronic infection in immunosuppressed people Others: e.g. -

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. -

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.

Comment Letter
July 23, 2008 Subject: Follow-up on July 22 Meeting Dr. Sirri et al.: I thank you for meeting with Ken Salomon, John Welborn and me yesterday afternoon to discuss Reg SHO, naked short selling and the SEC's recent emergency order. As a follow-up, I want to emphasize the following points: 1. OSTK continues to believe that it is critical that the SEC extend the pre-borrow requirement of the emergency order to the entire market, not just the 19 select companies. OSTK requests that the SEC promptly undertake swift rulemaking so that this protection applies fairly across the market. 2. OSTK continues to support the prompt and full elimination of the option market maker exception, an exception that swallows up the good intentions of Reg SHO. During yesterday's meeting, we discussed the relationship between the markets for equities and their corresponding derivatives (including listed options). You stated that options market makers enjoy an exception from the Reg SHO requirement that they locate and/or deliver shares when hedging against options positions. I am not sure that I would read Reg SHO to say that. However, under your theory, if an options market maker sells a put with a 6- month expiration, then that same market maker has the legal right to naked short and fail to deliver an equivalent amount of the underlying equity (leaving the option market maker "delta neutral”) for six months. This exception is unnecessary and open to abuse/manipulation, particularly with the married puts that often occur in Reg SHO threshold securities. -

Rev. Drug. Discov. showing trends in count and value over time.1 FDA approvals are from FDA’s Center for Drug Evaluation and Research (CDER) and Center for Biologics Evaluation and Research (CBER),2 peak sales estimates are from EvaluatePharma®,3 and R&D spend data are from BCG Value Science, inflation-adjusted using the standard global GDP-based inflator from the Economist Intelligence Unit.4 For additional details on methodology, see Schulze, Baedeker, Chen and Greber.5 Eroom’s Law is linear on a log scale through 2010, with an average increase approximately 12% per annum, or a halving of productivity approximately every seven years. If this holds true even after 2010, we would see a continuation of the linear development of the number of drugs approved per billion US$ R&D spending when using a logarithmic scale. To demonstrate that the deviation from regression after 2010 is statistically relevant we assumed the following: 1) Eroom's law is true up to 2010. 2) Eroom's law is not true between 2010 and 2018. To confirm our assumptions, we used a log-linear regression to describe the number of new molecular entities (NMEs) approved by the US FDA per billion US$ R&D spending from 1950–2010. -
