2013
Rescue of recombinant arenaviruses from cloned cDNAs, an approach referred to as reverse genetics, allows researchers to investigate the role of specific viral gene products, as well as the contribution of their different specific domains and residues, to many different aspects of the biology of arenavirus. Likewise, reverse genetics techniques in FDA-approved cell lines (Vero) for vaccine development provides novel possibilities for the generation of effective and safe vaccines to combat human...

We describe a technique for labeling and tracking stem cells with FDA-approved, superparamagnetic iron oxide (SPIO), ferumoxytol (Feraheme). This cellular imaging technique that utilizes magnetic resonance (MR) imaging for visualization, is readily accessible for long-term monitoring and diagnosis of successful or unsuccessful stem cell engraftments in patients.

Post-approval, manufacturers may modify an approved new or generic drug product. Such modifications can encompass alterations in the Active Pharmaceutical Ingredient (API), manufacturing process, formulation, batch size, manufacturing site, and container closure system (FDA Guidance for Industry, April 2004). Often, a drug product may undergo multiple changes.These modifications require careful evaluation to determine their potential impact on the drug product's identity, strength, quality,...

Epigenetic Regulation

2019
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer. In most mammals, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY). The X chromosome contains significantly more genes than the Y chromosome. Therefore, to prevent an excess of X chromosome-linked gene expression in females, one of the two X chromosomes is randomly silenced during early development.
FAQs
Requirements are shaped by both the product category and its intended use. A chemical substance incorporated into a drug, food, cosmetic, biologic, or device may therefore be evaluated under a different regulatory framework. This distinction affects the evidence expected, the analytical testing performed, the manufacturing controls applied, and the labeling or review pathway used.
Analytical method validation establishes whether a test produces reliable data for its intended purpose. In chemistry, that purpose may include confirming identity, measuring composition, or detecting impurities. Reliable methods allow researchers and manufacturers to distinguish genuine product variation from measurement problems, making test results more useful during approval activities and ongoing quality control.
Impurity control is central because unwanted chemical components can affect a product’s quality and safety. Regulatory expectations therefore connect impurity detection with characterization, analytical testing, and manufacturing controls. Tracking these elements together helps show that composition remains within the intended standard, rather than relying on a single measurement taken from an isolated sample.
A chemistry-focused regulatory workflow begins by characterizing the relevant substances and defining the composition that must be controlled. Researchers then select and validate analytical methods, test materials for identity and impurities, document the results, and use the findings to support manufacturing and review. This sequence links laboratory evidence with consistent production.
Documentation converts experimental and manufacturing observations into a traceable body of evidence. Records of analytical testing, method validation, composition, and manufacturing controls help demonstrate how conclusions were reached and whether production remained consistent. For researchers and manufacturers, thorough documentation supports product approval, facilitates quality assessment, and provides a basis for addressing later questions about the data.
Premarket review and postmarket monitoring serve different points in a product’s life cycle. Premarket work uses scientific evidence, testing, and documentation to support an initial regulatory decision. After a product enters use, monitoring can provide information relevant to continuing quality and safety. Together, these stages extend oversight beyond a single approval assessment.
