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...

FAQs
An FDA decision weighs the total evidence against potential benefits and risks rather than relying on a single study result. Reviewers consider clinical findings, adverse effects, manufacturing controls, labeling, and the overall benefit-risk profile. This integrated judgment helps determine whether the evidence supports approval and patient access.
Clinical phases provide complementary information about a drug’s safety, dosing, efficacy, and adverse effects. Examining these outcomes across phases allows sponsors and reviewers to evaluate the drug in a progressively developed body of human evidence. The resulting information supports assessment of whether the drug’s benefits justify its identified risks.
Clinical results do not represent the entire evidence package reviewed by the FDA. Manufacturing controls address whether the drug is produced consistently, while labeling forms part of the information examined with the clinical and safety findings. Considering these elements together supports a broader evaluation of the product’s readiness for patient access.
Sponsors begin with laboratory and preclinical studies before requesting authorization for human research. They then submit an Investigational New Drug application, or IND, to support the transition into clinical testing. This step connects earlier scientific evidence with planned assessments of safety, dosing, efficacy, and adverse effects in people.
After successful clinical studies, the sponsor submits a New Drug Application or a Biologics License Application. FDA reviewers then examine the submitted evidence together with manufacturing controls, labeling, and the overall benefit-risk profile. This formal review determines whether the accumulated information supports the regulatory decision needed for market access.
Approval does not end regulatory evaluation. Postmarketing surveillance continues to identify rare risks that may not be apparent during earlier studies. These observations can guide later regulatory decisions and refine understanding of the drug’s safety profile as patient exposure expands beyond the clinical studies used for the initial review.
