Chinese Researcher Returns Home After DOJ Moves to Drop a Spate of Cases 

A year ago, the allegations of espionage against Chinese scientists reached a fever pitch as the US abruptly ordered China to shut down its Houston consulate and, on the same day, announced it had charged four visiting Chinese researchers for concealing their ties to the Chinese military in visa applications. Over the past few days, though, the Department of Justice has moved to drop those cases. “Recent developments in a handful of cases involving defendants with alleged, undisclosed ties to the People’s Liberation Army of the People’s Republic of China have prompted the department to re-evaluate these prosecutions,” Wyn Hornbuckle, a spokesman, told the New York Times without elaborating on the specifics.

Pfizer, Johnson & Johnson Settle High-Profile Remicade Biosimilar Lawsuit  

For nearly four years, biopharma heavyweights Johnson & Johnson and Pfizer have sparred in court over competitive dynamics of the biosimilar industry, demanding the attention of the industry in a groundbreaking case that had some promise to serve as a bellwether for the future. Instead, the closely-watched battle, in which Pfizer claimed J&J unfairly stifled competition for Pfizer’s once-promising biosimilar Inflectra, has ended quietly. The companies confirmed this week that they have settled their case, with the terms undisclosed. The settlement was first reported by the American Journal of Managed Care.

National Scotch Day

Observed each year on July 27, National Scotch Day celebrates the iconic whisky. In order to be considered scotch, this classy and distinctive spirit must be made in Scotland. It must be fermented from malted barley, aged in oak barrels for at least three years and have an ABV or alcohol content of less than 94.8%. While most scotch is made with barley, water and yeast; other grains can be included.  All fermentation additives are excluded, per law. There are five distinct classifications of Scotch whisky including single malt scotch, single grain scotch, blended malt scotch, blended grain scotch and blended scotch. Scotch is often identified by the region where it was produced and each region has its own characteristics that influence taste. Despite scotch being made in Scotland, you can enjoy the spirit anywhere. Kilt not required.

Evidence-Based Guidelines for Controlling pH in Mammalian Live-Cell Culture Systems

A fundamental variable in culture medium is its pH, which must be controlled by an appropriately formulated buffering regime, since biological processes are exquisitely sensitive to acid–base chemistry. Although awareness of the importance of pH is fostered early in the training of researchers, there are no consensus guidelines for best practice in managing pH in cell cultures, and reporting standards relating to pH are typically inadequate. Furthermore, many laboratories adopt bespoke approaches to controlling pH, some of which inadvertently produce artefacts that increase noise, compromise reproducibility or lead to the misinterpretation of data. Here, we use real-time measurements of medium pH and intracellular pH under live-cell culture conditions to describe the effects of various buffering regimes.

Impacts on Product Quality Attributes of Monoclonal Antibodies Produced in CHO Cell Bioreactor Cultures During Intentional Mycoplasma Contamination Events 

A mycoplasma contamination event in a biomanufacturing facility can result in costly cleanups and potential drug shortages. Mycoplasma may survive in mammalian cell cultures with only subtle changes to the culture and penetrate the standard 0.2‐µm filters used in the clarification of harvested cell culture fluid. In this report, we studied the changes in the IgG1 product quality produced by CHO cells considered to be induced by the M. arginini contamination events. We observed changes in critical quality attributes correlated with the duration of contamination, including increased acidic charge variants and high mannose species, which were further modeled using principal component analysis to explore the relationships among M. arginini contamination, CHO cell growth and metabolites, and IgG1 product quality attributes.

Media Management Fuels Process Intensification

Thursday, July 29th, 2021

The intensification of an upstream typically requires much higher media volume requirements. Scheduling all this extra demand and modeling the additional equipment such that the right utilization, storage, and ergonomics are achieved for both operator and unit operation layout will mean no preparation bottlenecks, cleanroom congestion, and costly over-equipping. As upstream intensification demands more media, the risk of contamination or impact of leaks and failures becomes more evident and expensive. Mitigating these risks with an instrumentation toolbox of pre, point-of-use, and post media preparation checks allows for confidence in this productivity increase.

In-Line Detection of Monoclonal Antibodies in the Effluent of Protein A Chromatography with QCM Sensor 

A major drawback of the IgG capture step is the high cost of the protein A resin. For a better utilization of the resin, a continuous multi-column operation was recently proposed. In this method, accurate detection of leaking IgG is crucial to divert the breakthrough fluid from the waste to the next column and prolong the loading step without product loss. The detection of a breakthrough point as a change in UV absorption is based on a relatively small signal addition of IgGs to the bulk signal of host cell proteins. To achieve specificity, we used a quartz crystal microbalance and immobilized protein A as specific ligand on the sensor surface. We integrated the quartz crystal microbalance sensor in-line after the protein A column for real-time detection of IgGs in the breakthrough fluid. We show that this specific IgG detection in the breakthrough fluid can be more sensitive than with the UV detector.

FDA Rejects Incyte Cancer Drug, Asking for More Data to Show Clinical Benefit 

An Incyte drug developed to treat a rare type of anal cancer still has a shot at FDA approval, but the company needs to produce more clinical data from a larger study to support its application. The regulator rejected Incyte’s submission, which was based on data from a Phase 2 study. The complete response letters that the FDA sends to companies are not public. According to Wilmington, Delaware-based Incyte, the correspondence states that the regulator needs to see additional data to demonstrate the drug’s clinical benefit treating patients with squamous cell carcinoma of the anal canal (SCAC) that has advanced or spread. The company said it is reviewing the letter and will discuss the next steps for the drug with the agency.

New Understanding of Cell Stability with Potential to Improve Immune Cell Therapies 

Research in mice, published in Science Immunology by researchers at the Babraham Institute, UK and VIB-KU Leuven, Belgium, provides two solutions with potential to overcome a key clinical limitation of immune cell therapies. Regulatory T cells have potential in treating autoimmunity and inflammatory diseases yet they can switch from a protective to damaging function. By identifying the unstable regulatory T cells, and understanding how they can be purged from a cell population, the authors highlight a path forward for regulatory T cell transfer therapy.

Disposable Flowcell for Spectroscopic Analysis in Bioprocesses 

The US FDA has high regulatory and quality requirements for the development and more importantly production of pharmaceuticals. Ideally, the production process is continuously monitored and recorded noninvasively to allow immediate control action if necessary. There are a multitude of established optical detection systems for classical stainless steel bioreactors using fiber optic probes, light guides, light sources and detectors for absorbance, fluorescence and Raman detection techniques. These systems are steam-sterilizable in place, reusable but are complex and expensive. Such systems are not well suited to use on the growing market of pre-sterilized disposable bioreactors, since there is a lack of sterile interface technology. A novel disposable and pre-sterilized flow cell has been developed, which can be easily connected to disposable bioreactors by sterile tube connections.
