They prepare and submit necessary registration documents, negotiate with regulatory authorities, and ensure that products remain compliant and available. Beyond paperwork, they provide critical technical and strategic guidance throughout drug development, making a significant impact on both the financial and clinical success of a company.(17)
The U.S. Food and Drug Administration (FDA) plays a critical role in ensuring that drugs and biological products meet rigorous standards for safety, efficacy, and quality before they reach consumers. Various application processes exist depending on the type of drug or biologic being developed. Below is an overview of the key regulatory pathways for drug approval.(18)
4.1 Investigational New Drug (IND) Application
Before a pharmaceutical company can test a new drug on humans, it must seek FDA approval through an Investigational New Drug (IND) application. Under federal law, a drug must have an approved marketing application before it can be transported across state lines. However, since clinical trials typically involve multiple locations across the country, sponsors must obtain an exemption from this rule. The IND application serves as this exemption, allowing companies to ship investigational drugs to research sites while regulatory authorities assess their safety for human testing. The IND process includes preclinical data, proposed study designs, and information on drug manufacturing.(19)
4.2 New Drug Application (NDA)
Once sufficient clinical trial data demonstrates that a drug is safe and effective, the sponsor submits a New Drug Application (NDA) to the FDA. This application includes comprehensive scientific data, including details on the drug’s chemistry, pharmacology, biopharmaceutics, medical effects, and statistical analysis. The NDA undergoes a rigorous review to determine whether the drug meets regulatory standards for marketing approval. If approved, the drug can be legally marketed and prescribed in the U.S. Each NDA receives a unique tracking number for internal monitoring.(20)
4.3 Abbreviated New Drug Application (ANDA) – Generic Drug Approval
Unlike new drugs, generic drugs do not require extensive preclinical and clinical studies to prove their safety and efficacy. Instead, manufacturers submit an Abbreviated New Drug Application (ANDA) to the FDA’s Center for Drug Evaluation and Research (CDER), Office of Generic Drugs. The key requirement for approval is bioequivalence—the generic drug must perform in the same manner as the original brand-name drug. This means it must deliver the same active ingredients at the same rate and extent in the body. Once approved, generics offer a safe, effective, and more affordable alternative for consumers.(21)
4.4 Over-the-Counter (OTC) Drugs
Over-the-counter (OTC) medications are non-prescription drugs available directly to consumers. These drugs play a significant role in public health, allowing people to manage common ailments like pain, allergies, and colds without visiting a doctor. OTC drugs fall into over 80 therapeutic categories, including skincare, digestive health, and weight management. The CDER regulates these products, ensuring that they are properly labeled and that their benefits outweigh any risks. Some prescription medications transition to OTC status after extensive review and public health considerations.(22)
4.5 Biologics License Application (BLA)
Biologic products, such as vaccines, gene therapies, and monoclonal antibodies, differ from traditional chemical drugs and are regulated under the Public Health Service (PHS) Act. Companies manufacturing biologics for commercial sale must obtain a Biologics License Application (BLA). This application details the manufacturing process, chemistry, pharmacology, clinical pharmacology, and medical effects of the biologic product. If the FDA determines that the data meets its stringent requirements, a license is issued allowing the company to market the product in the U.S.(23)
Each country has its own regulatory agency responsible for overseeing and enforcing laws related to drug development. These agencies establish guidelines for the licensing, registration, manufacturing, marketing, and labelling of pharmaceutical products to ensure safety, efficacy, and quality compliance.
