Understanding Quality Paradigm Shifts in the Evolving Pharmaceutical Landscape: Perspectives from the USP Quality Advisory Group.

Recent changes in the pharmaceutical industry have led to significant paradigm shifts in the pharmaceutical quality environment. Globalization of the pharmaceutical industry, increasingly rapid development of novel therapies, and adoption of new manufacturing techniques have presented numerous challenges for the established regulatory framework and quality environment and are impacting the approaches utilized to ensure the quality of pharmaceutical products. Regulators, industry, and standards-setting organizations have begun to recognize the need to rely more on integrated risk-based approaches and to create more nimble and flexible standards to complement these efforts.

COVID-19 vaccine platforms: Delivering on a promise?

The emergence of the novel SARS-CoV-2 and COVID-19 has brought into sharp focus the need for a vaccine to prevent this disease. Vaccines have saved millions of lives since their introduction to the public over 200 years ago. The potential for vaccination reached new heights in the mid-20th century with the development of technologies that expanded the ability to create novel vaccines.

Do Standards Matter? What is Their Value?

Standards allow us to manage expectations for a diverse range of goods and services across the globe. From coordinating international global telecommunications across 24 different time zones to ensuring access to safe drinking water, standards allow us to work, communicate, collaborate, and live with certain expectations about safety and efficacy. When standards are fit-for-purpose, they raise the quality of products and services without requiring us to think about how that quality is assured.

Dietary supplements quality analysis tools from the United States Pharmacopeia.

The United States Food and Drug Administration (FDA) issued the dietary supplement (DS) current good manufacturing practice (GMP) regulations in compliance with the mandate from the Dietary Supplements Health and Education Act (DSHEA), with the intention of protecting public health by ensuring the quality of DS. The GMP regulations require manufacturers to establish their own quality specifications for identity, purity, strength, composition, and absence of contaminants. Numerous FDA-conducted GMP inspections found that the private specifications set by these manufacturers are often insufficient to ensure adequate quality of dietary ingredients and DS.

Biosimilar monoclonal antibodies: the scientific basis for extrapolation.

Introduction: Biosimilars are biologic products that receive authorization based on an abbreviated regulatory application containing comparative quality and nonclinical and clinical data that demonstrate similarity to a licensed biologic product. Extrapolation of safety and efficacy has emerged as an important way to simplify biosimilar development. Regulatory authorities have generally reached the consensus that extrapolation of similarity from one indication to other approved indications of the reference product can be permitted if it is scientifically justified.

Consistency of quality attributes for the glycosylated monoclonal antibody Humira® (adalimumab).

Humira® (adalimumab) is a recombinant human IgG1 monoclonal antibody (mAb) glycoprotein consisting of 1330 amino acids that is specific for human tumor necrosis factor (TNF). The biological activity and clinical profile of mAb therapeutics, including adalimumab, is influenced by their protein structure and glycosylation patterns, which can be affected by the expression system, cell culture conditions and purification process methodology. While clinical outcome cannot yet be attributed to many of the individual structural features that constitute a mAb, it is evident that detailed structural attribute analysis is necessary if structural contributions to function are to be comprehensively defined.

Deletions in the S1 domain of Rrp5p cause processing at a novel site in ITS1 of yeast pre-rRNA that depends on Rex4p.

Rrp5p is the only protein so far known to be required for the processing of yeast pre-rRNA at both the early sites A0, A1 and A2 leading to 18S rRNA and at site A3, the first step specific for the pathway leading to 5.8S/25S rRNA. Previous in vivo mutational analysis of Rrp5p demonstrated that the first 8 of its 12 S1 RNA-binding motifs are involved in the formation of the 'short' form of 5.
