An approved drug is a medicinal preparation that has been validated for a therapeutic use by a ruling authority of a government. [1] This process is usually specific by country, unless specified otherwise.
In the United States, the FDA approves drugs. Before a drug can be prescribed, it must undergo the FDA's approval process. While a drug can feasibly be used off-label (for non-approved indications), it still is required to be approved for a specific disease or medical condition. [2] Drug companies seeking to sell a drug in the United States must first test it. The company then sends the Food and Drug Administration's Center for Drug Evaluation and Research (CDER) [3] evidence from these tests to prove the drug is safe and effective for its intended use. A fee is required to make such FDA submission. For financial year 2020, this fee was: for an application requiring clinical data ($2,942,965) and for an application not requiring clinical data ($1,471,483). [4] A team of CDER physicians, statisticians, chemists, pharmacologists, and other scientists reviews the company's data and proposed labeling. If this independent and unbiased review establishes that a drug's health benefits outweigh its known risks, the drug is approved for sale. The center doesn't actually test drugs itself, although it does conduct limited research in the areas of drug quality, safety, and effectiveness standards.
As of the end of 2013, the FDA and its predecessors had approved 1,452 drugs, though not all are still available, and some have been withdrawn for safety reasons. [5] Accounting for subsequent corporate acquisitions, these approvals were earned by approximately 100 different organizations. [5]
In the European Union, it is the European Medicines Agency (EMA) that evaluates medicinal products.
In Japan, the agency regulating medicinal products is Pharmaceuticals and Medical Devices Agency (PMDA).
On average, only one in every 5,000 compounds that makes it through lead development to the stage of preclinical development becomes an approved drug. Only 10% of all drugs started in human clinical trials become an approved drug. [6] [7] [8]
The United States Food and Drug Administration is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, animal foods & feed and veterinary products.
An orphan drug is a pharmaceutical agent developed to treat medical conditions which, because they are so rare, would not be profitable to produce without government assistance. The conditions are referred to as orphan diseases.
The Food and Drug Administration's (FDA) New Drug Application (NDA) is the vehicle in the United States through which drug sponsors formally propose that the FDA approve a new pharmaceutical for sale and marketing. Some 30% or less of initial drug candidates proceed through the entire multi-year process of drug development, concluding with an approved NDA, if successful.
The United States Food and Drug Administration's Investigational New Drug (IND) program is the means by which a pharmaceutical company obtains permission to start human clinical trials and to ship an experimental drug across state lines before a marketing application for the drug has been approved. Regulations are primarily at 21 CFR 312. Similar procedures are followed in the European Union, Japan, and Canada.
Drug development is the process of bringing a new pharmaceutical drug to the market once a lead compound has been identified through the process of drug discovery. It includes preclinical research on microorganisms and animals, filing for regulatory status, such as via the United States Food and Drug Administration for an investigational new drug to initiate clinical trials on humans, and may include the step of obtaining regulatory approval with a new drug application to market the drug. The entire process – from concept through preclinical testing in the laboratory to clinical trial development, including Phase I–III trials – to approved vaccine or drug typically takes more than a decade.
The Center for Biologics Evaluation and Research (CBER) is one of six main centers for the U.S. Food and Drug Administration (FDA), which is a part of the U.S. Department of Health and Human Services. The current Director of CBER is Peter Marks, M.D., PhD. CBER is responsible for assuring the safety, purity, potency, and effectiveness of biologics and related products. Not all biologics are regulated by CBER. Monoclonal antibodies and other therapeutic proteins are regulated by the FDA Center for Drug Evaluation and Research (CDER).
Clinical research is a branch of healthcare science that determines the safety and effectiveness (efficacy) of medications, devices, diagnostic products and treatment regimens intended for human use. These may be used for prevention, treatment, diagnosis or for relieving symptoms of a disease. Clinical research is different from clinical practice. In clinical practice established treatments are used, while in clinical research evidence is collected to establish a treatment.
An Abbreviated New Drug Application (ANDA) is an application for a U.S. generic drug approval for an existing licensed medication or approved drug.
In medicine, an indication is a valid reason to use a certain test, medication, procedure, or surgery. There can be multiple indications to use a procedure or medication. An indication can commonly be confused with the term diagnosis. A diagnosis is the assessment that a particular [medical] condition is present while an indication is a reason for use. The opposite of an indication is a contraindication, a reason to withhold a certain medical treatment because the risks of treatment clearly outweigh the benefits.
The Center for Drug Evaluation and Research is a division of the U.S. Food and Drug Administration (FDA) that monitors most drugs as defined in the Food, Drug, and Cosmetic Act. Some biological products are also legally considered drugs, but they are covered by the Center for Biologics Evaluation and Research. The center reviews applications for brand name, generic, and over the counter pharmaceuticals, manages US current Good Manufacturing Practice (cGMP) regulations for pharmaceutical manufacturing, determines which medications require a medical prescription, monitors advertising of approved medications, and collects and analyzes safety data about pharmaceuticals that are already on the market.
The Prescription Drug User Fee Act (PDUFA) was a law passed by the United States Congress in 1992 which allowed the Food and Drug Administration (FDA) to collect fees from drug manufacturers to fund the new drug approval process. The Act provided that the FDA was entitled to collect a substantial application fee from drug manufacturers at the time a New Drug Application (NDA) or Biologics License Application (BLA) was submitted, with those funds designated for use only in Center for Drug Evaluation and Research (CDER) or Center for Biologics Evaluation and Research (CBER) drug approval activities. In order to continue collecting such fees, the FDA is required to meet certain performance benchmarks, primarily related to the speed of certain activities within the NDA review process.
President of the United States George W. Bush signed the Food and Drug Administration Amendments Act of 2007 (FDAAA) on September 27, 2007. This law reviewed, expanded, and reaffirmed several existing pieces of legislation regulating the FDA. These changes allow the FDA to perform more comprehensive reviews of potential new drugs and devices. It was sponsored by Reps. Joe Barton and Frank Pallone and passed unanimously by the Senate.
An experimental drug is a medicinal product that has not yet received approval from governmental regulatory authorities for routine use in human or veterinary medicine. A medicinal product may be approved for use in one disease or condition but still be considered experimental for other diseases or conditions. In 2018 the United States of America signed the legislation "Right to Try", this allows individuals who fit into the criteria to try experimental drugs that are not yet deemed safe.
A glossary of terms used in clinical research.
The following outline is provided as an overview of and topical guide to clinical research:
The phases of clinical research are the stages in which scientists conduct experiments with a health intervention to obtain sufficient evidence for a process considered effective as a medical treatment. For drug development, the clinical phases start with testing for safety in a few human subjects, then expand to many study participants to determine if the treatment is effective. Clinical research is conducted on drug candidates, vaccine candidates, new medical devices, and new diagnostic assays.
Breakthrough therapy is a United States Food and Drug Administration designation that expedites drug development that was created by Congress under Section 902 of the 9 July 2012 Food and Drug Administration Safety and Innovation Act. The FDA's "breakthrough therapy" designation is not intended to imply that a drug is actually a "breakthrough" or that there is high-quality evidence of treatment efficacy for a particular condition; rather, it allows the FDA to grant priority review to drug candidates if preliminary clinical trials indicate that the therapy may offer substantial treatment advantages over existing options for patients with serious or life-threatening diseases. The FDA has other mechanisms for expediting the review and approval process for promising drugs, including fast track designation, accelerated approval, and priority review.
A botanical drug is defined in the United States Federal Food, Drug, and Cosmetic Act as a botanical product that is marketed as diagnosing, mitigating, treating, or curing a disease; a botanical product in turn, is a finished, labeled product that contains ingredients from plants. Chemicals that are purified from plants, like paclitaxel, and highly purified products of industrial fermentation, like biopharmaceuticals, are not considered to be botanical products.
Janet Woodcock is an American physician and former Acting Commissioner of the U.S. Food and Drug Administration (FDA). She joined the FDA in 1986, and has held a number of senior leadership positions there, including terms as the Director of Center for Drug Evaluation and Research (CDER) from 1994 to 2004 and 2007 to 2021.
Zanubrutinib, sold under the brand name Brukinsa, is a medication used for the treatment of mantle cell lymphoma (MCL), Waldenström's macroglobulinemia (WM), marginal zone lymphoma (MZL), and chronic lymphocytic leukemia (CLL). Zanubrutinib is classified as a Bruton's tyrosine kinase (BTK) inhibitor. It is given by mouth.
On average, only one in every 5,000 compounds that drug companies discover and put through preclinical testing becomes an approved drug. Of the drugs started in clinical trials on humans, only 10 percent secure F.D.A. approval. ...
