FDA Approved Drugs: Changes to Approved Drugs
0 Views •
2025
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,...

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.

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...

Blood Collection in a Pig Model
0 Views •
2026
All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Blood collection is a common procedure in swine research and clinical studies. The choice of sampling site depends on the animal's age, body size, the volume of blood required, the study objectives and approved IACUC...
FAQs
Replacement, reduction, and refinement shape the committee’s judgment about whether animal use is necessary and how it can be made more responsible. Replacement asks whether live vertebrate animals can be avoided, reduction concerns limiting the number used, and refinement focuses on improving procedures to lessen pain or distress. Together, these principles connect scientific justification with welfare protections.
Pain and distress are central review considerations because animal procedures can create welfare concerns that affect ethical acceptability and study conduct. The protocol must identify potential discomfort and establish humane endpoints, meaning defined points for responding to animal welfare concerns. This planning gives the committee a basis for evaluating whether proposed procedures remain responsibly controlled.
Animal welfare review extends beyond the experimental manipulation itself. IACUC evaluation considers where animals are housed, how procedures are performed, and whether personnel have appropriate training. These elements matter because responsible conduct depends on the full research environment, not only the study question. In biology investigations, aligning housing, procedures, and staff preparation supports consistent oversight of animal use.
An approved protocol is not the end of oversight. Continuing accountability includes monitoring the protocol, reviewing proposed modifications, and addressing unexpected animal-related concerns. This ongoing process allows animal-use practices to be reconsidered when study conditions change or unforeseen welfare issues arise. As a result, authorization functions as continuing responsibility rather than a one-time administrative decision.
To seek IACUC approval, investigators must present a study protocol that explains the scientific rationale for using live vertebrate animals and describes the planned animal-related work. The committee then examines the proposed use, housing, procedures, possible pain or distress, humane endpoints, and personnel training. Authorization follows after these elements have been considered together.
In biology, IACUC oversight is relevant across studies of physiology, behavior, disease, and drug development, because each area may require different forms of animal use and procedural planning. The review links the research objective to animal welfare safeguards, helping determine whether the proposed work is scientifically justified and responsibly conducted. It therefore supports research while maintaining institutional accountability.
