Biomedical research (or experimental medicine) encompasses a wide array of research, extending from "basic research" (also called bench science or bench research), – involving fundamental scientific principles that may apply to a preclinical understanding – to clinical research, which involves studies of people who may be subjects in clinical trials. Within this spectrum is applied research, or translational research, conducted to expand knowledge in the field of medicine.
Basic research, also called pure research or fundamental research, has the scientific research aim to improve scientific theories for improved understanding or prediction of natural or other phenomena. Applied research, in turn, uses scientific theories to develop technology or techniques to intervene and alter natural or other phenomena. Though often driven by curiosity, basic research fuels applied science's innovations. The two aims are often coordinated in research and development.
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.
Clinical trials are experiments or observations done in clinical research. Such prospective biomedical or behavioral research studies on human participants are designed to answer specific questions about biomedical or behavioral interventions, including new treatments and known interventions that warrant further study and comparison. Clinical trials generate data on safety and efficacy. They are conducted only after they have received health authority/ethics committee approval in the country where approval of the therapy is sought. These authorities are responsible for vetting the risk/benefit ratio of the trial – their approval does not mean that the therapy is 'safe' or effective, only that the trial may be conducted.
Both clinical and preclinical research phases exist in the pharmaceutical industry's drug development pipelines, where the clinical phase is denoted by the term clinical trial. However, only part of the clinical or preclinical research is oriented towards a specific pharmaceutical purpose. The need for fundamental and mechanism-based understanding, diagnostics, medical devices, and non-pharmaceutical therapies means that pharmaceutical research is only a small part of medical research.
A drug pipeline is the set of drug candidates that a pharmaceutical company has under discovery or development at any given point in time.
A medication is a drug used to diagnose, cure, treat, or prevent disease. Drug therapy (pharmacotherapy) is an important part of the medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management.
Medical diagnosis is the process of determining which disease or condition explains a person's symptoms and signs. It is most often referred to as diagnosis with the medical context being implicit. The information required for diagnosis is typically collected from a history and physical examination of the person seeking medical care. Often, one or more diagnostic procedures, such as medical tests, are also done during the process. Sometimes posthumous diagnosis is considered a kind of medical diagnosis.
The increased longevity of humans over the past century can be significantly attributed to advances resulting from medical research. Among the major benefits of medical research have been vaccines for measles and polio, insulin treatment for diabetes, classes of antibiotics for treating a host of maladies, medication for high blood pressure, improved treatments for AIDS, statins and other treatments for atherosclerosis, new surgical techniques such as microsurgery, and increasingly successful treatments for cancer.[ citation needed ] New, beneficial tests and treatments are expected as a result of the Human Genome Project. Many challenges remain, however, including the appearance of antibiotic resistance and the obesity epidemic.
A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylactic, or therapeutic.
Measles is a highly contagious infectious disease caused by the measles virus. Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days. Initial symptoms typically include fever, often greater than 40 °C (104 °F), cough, runny nose, and inflamed eyes. Small white spots known as Koplik's spots may form inside the mouth two or three days after the start of symptoms. A red, flat rash which usually starts on the face and then spreads to the rest of the body typically begins three to five days after the start of symptoms. Common complications include diarrhea, middle ear infection (7%), and pneumonia (6%). These occur in part due to measles-induced immunosuppression. Less commonly seizures, blindness, or inflammation of the brain may occur. Other names include morbilli, rubeola, red measles, and English measles. Both rubella, also known as "German measles", and roseola are different diseases caused by unrelated viruses.
Polio, also called poliomyelitis or infantile paralysis, is an infectious disease caused by the poliovirus. In about 0.5 percent of cases there is muscle weakness resulting in an inability to move. This can occur over a few hours to a few days. The weakness most often involves the legs but may less commonly involve the muscles of the head, neck and diaphragm. Many people fully recover. In those with muscle weakness about 2 to 5 percent of children and 15 to 30 percent of adults die. Another 25 percent of people have minor symptoms such as fever and a sore throat and up to 5 percent have headache, neck stiffness and pains in the arms and legs. These people are usually back to normal within one or two weeks. In up to 70 percent of infections there are no symptoms. Years after recovery post-polio syndrome may occur, with a slow development of muscle weakness similar to that which the person had during the initial infection.
Most of the research in the field is pursued by biomedical scientists, but significant contributions are made by other type of biologists. Medical research on humans, has to strictly follow the medical ethics sanctioned in the Declaration of Helsinki and hospital review board where the research is conducted. In all cases, research ethics are expected.
A biomedical scientist is a scientist trained in biology, particularly in the context of medicine. These scientists work to gain knowledge on the main principles of how the human body works and to find new ways to cure or treat disease by developing advanced diagnostic tools or new therapeutic strategies. The research of biomedical scientists is referred to as biomedical research.
A biologist is a scientist who has specialized knowledge in the field of biology, the scientific study of life. Biologists involved in fundamental research attempt to explore and further explain the underlying mechanisms that govern the functioning of living matter. Biologists involved in applied research attempt to develop or improve more specific processes and understanding, in fields such as medicine and industry.
Medical ethics is a system of moral principles that apply values to the practice of clinical medicine and in scientific research. Medical ethics is based on a set of values that professionals can refer to in the case of any confusion or conflict. These values include the respect for autonomy, non-maleficence, beneficence, and justice. Such tenets may allow doctors, care providers, and families to create a treatment plan and work towards the same common goal. It is important to note that these four values are not ranked in order of importance or relevance and that they all encompass values pertaining to medical ethics. However, a conflict may arise leading to the need for hierarchy in an ethical system, such that some moral elements overrule others with the purpose of applying the best moral judgement to a difficult medical situation.
Example areas in basic medical research include cellular and molecular biology, medical genetics, immunology, neuroscience, and psychology. Researchers, mainly in universities or government-funded research institutes, aim to establish an understanding of the cellular, molecular and physiological mechanisms of human health and disease.
Molecular biology is a branch of biology that concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, proteins and their biosynthesis, as well as the regulation of these interactions. Writing in Nature in 1961, William Astbury described molecular biology as:
...not so much a technique as an approach, an approach from the viewpoint of the so-called basic sciences with the leading idea of searching below the large-scale manifestations of classical biology for the corresponding molecular plan. It is concerned particularly with the forms of biological molecules and [...] is predominantly three-dimensional and structural – which does not mean, however, that it is merely a refinement of morphology. It must at the same time inquire into genesis and function.
Neuroscience is the scientific study of the nervous system. It is a multidisciplinary branch of biology that combines physiology, anatomy, molecular biology, developmental biology, cytology, mathematical modeling and psychology to understand the fundamental and emergent properties of neurons and neural circuits. The understanding of the biological basis of learning, memory, behavior, perception, and consciousness has been described by Eric Kandel as the "ultimate challenge" of the biological sciences.
Preclinical research covers understanding of mechanisms that may lead to clinical research with people. Typically, the work requires no ethical approval, is supervised by scientists rather than physicians, and is carried out in a university or company, rather than a hospital.
A physician, medical practitioner, medical doctor, or simply doctor, is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.
Clinical research is carried out with people as the experimental subjects. It is generally supervised by physicians and conducted by nurses in a medical setting, such as a hospital or research clinic, and requires ethical approval.

Research funding in many countries derives from research bodies and private organizations which distribute money for equipment, salaries, and research expenses. In the United Kingdom, funding bodies such as the Medical Research Council derive their assets from UK tax payers, and distribute revenues to institutions by competitive research grants. The Wellcome Trust is the UK's largest non-governmental source of funds for biomedical research and provides over £600 million per year in grants to scientists and funds for research centres.
In the United States, data from ongoing surveys by the National Science Foundation (NSF) show that federal agencies provided only 44% of the $86 billion spent on basic research in 2015.The National Institutes of Health and pharmaceutical companies collectively contribute $26.4 billion and $27 billion, which constitute 28% and 29% of the total, respectively. Other significant contributors include biotechnology companies ($17.9 billion, 19% of total), medical device companies ($9.2 billion, 10% of total), other federal sources, and state and local governments. Foundations and charities, led by the Bill and Melinda Gates Foundation, contributed about 3% of the funding. These funders are attempting to maximize their return on investment in public health. One method proposed to maximize the return on investment in medicine is to fund the development of open source hardware for medical research and treatment.
The enactment of orphan drug legislation in some countries has increased funding available to develop drugs meant to treat rare conditions, resulting in breakthroughs that previously were uneconomical to pursue.
Since the establishment of the National Institutes of Health (NIH) in the mid-1940s, the main source of U.S. federal support of biomedical research, investment priorities and levels of funding have fluctuated. From 1995 to 2010, NIH support of biomedical research increased from 11 billion to 27 billionDespite the jump in federal spending, advancements measured by citations to publications and the number of drugs passed by the FDA remained stagnant over the same time span. Financial projections indicate federal spending will remain constant in the near future.
The National Institutes of Health (NIH) is the agency that is responsible for management of the lion's share of federal funding of biomedical research.It funds over 280 areas directly related to health. Over the past century there were two notable periods of NIH support. From 1995 to 1996 funding increased from $8.877 billion to $9.366 billion, years which represented the start of what is considered the "doubling period" of rapid NIH support. The second notable period started in 1997 and ended in 2010, a period where the NIH moved to organize research spending for engagement with the scientific community.
Since 1980 the share of biomedical research funding from industry sources has grown from 32% to 62%,which has resulted in the development of numerous life-saving medical advances. The relationship between industry and government-funded research in the US has seen great movement over the years. The 1980 Bayh Dole Act was passed by Congress to foster a more constructive relationship between the collaboration of government and industry funded biomedical research. The Bayh Doyle Act gave private corporations the option of applying for government funded grants for biomedical research which in turn allowed the private corporations to license the technology. Both government and industry research funding increased rapidly from between the years of 1994–2003; industry saw a compound average annual growth rate of 8.1% a year and slowed only slightly to a compound average annual growth rate of 5.8% from 2003 to 2008.
"Conflict of interest" in the field of medical research has been defined as "a set of conditions in which professional judgment concerning a primary interest (such as a person's welfare or the validity of research) tends to be unduly influenced by a secondary interest (such as financial gain)."
Regulation on industry funded biomedical research has seen great changes since Samuel Hopkins Adams declaration. In 1906 congress passed the Pure Food and Drugs Act of 1906.In 1912 Congress passed the Shirley Amendment to prohibit the wide dissemination of false information on pharmaceuticals. The Food and Drug Administration was formally created in 1930 under the McNarey Mapes Amendment to oversee the regulation of Food and Drugs in the United States. In 1962 the Kefauver-Harris Amendments to the Food, Drug and Cosmetics Act made it so that before a drug was marketed in the United States the FDA must first approve that the drug was safe. The Kefauver-Harris amendments also mandated that more stringent clinical trials must be performed before a drug is brought to the market. The Kefauver-Harris amendments were met with opposition from industry due to the requirement of lengthier clinical trial periods that would lessen the period of time in which the investor is able to see return on their money. In the pharmaceutical industry patents are typically granted for a 20-year period of time, and most patent applications are submitted during the early stages of the product development. According to Ariel Katz on average after a patent application is submitted it takes an additional 8 years before the FDA approves a drug for marketing. As such this would leave a company with only 12 years to market the drug to see a return on their investments. After a sharp decline of new drugs entering the US market following the 1962 Kefauver-Harris amendments economist Sam Petlzman concluded that cost of loss of innovation was greater than the savings recognized by consumers no longer purchasing ineffective drugs. In 1984 the Hatch-Waxman Act or the Drug Price Competition and Patent Term Restoration Act of 1984 was passed by congress. The Hatch-Waxman Act was passed with the idea that giving brand manufacturers the ability to extend their patent by an additional 5 years would create greater incentives for innovation and private sector funding for investment.
The relationship that exists with industry funded biomedical research is that of which industry is the financier for academic institutions which in turn employ scientific investigators to conduct research. A fear that exists wherein a project is funded by industry is that firms might negate informing the public of negative effects to better promote their product.A list of studies show that public fear of the conflicts of interest that exist when biomedical research is funded by industry can be considered valid after a 2003 publication of "Scope and Impact of Financial Conflicts of Interest in Biomedical Research" in The Journal of American Association of Medicine. This publication included 37 different studies that met specific criteria to determine whether or not an academic institution or scientific investigator funded by industry had engaged in behavior that could be deduced to be a conflict of interest in the field of biomedical research. Survey results from one study concluded that 43% of scientific investigators employed by a participating academic institution had received research related gifts and discretionary funds from industry sponsors. Another participating institution surveyed showed that 7.6% of investigators were financially tied to research sponsors, including paid speaking engagements (34%), consulting arrangements (33%), advisory board positions (32%) and equity (14%). A 1994 study concluded that 58% out of 210 life science companies indicated that investigators were required to withhold information pertaining to their research as to extend the life of the interested companies' patents. Rules and regulations regarding conflict of interest disclosures are being studied by experts in the biomedical research field to eliminate conflicts of interest that could possibly affect the outcomes of biomedical research.
The earliest narrative describing a medical trial is found in the Book of Daniel, which says that Babylonian king Nebuchadnezzar ordered youths of royal blood to eat only red meat and wine for three years, while another group of youths ate only beans and water.The experiment was intended to determine if a diet of vegetables and water was healthier than a diet of wine and red meat. At the experiment endpoint, the trial accomplished its prerogative: the youths who ate only beans and water were noticeably healthier. Scientific curiosity to understand health outcomes from varying treatments has been present for centuries, but it was not until the mid-19th century when an organizational platform was created to support and regulate this curiosity. In 1945, Vannevar Bush said that biomedical scientific research was "the pacemaker of technological progress", an idea which contributed to the initiative to found the National Institutes of Health (NIH) in 1948, a historical benchmark that marked the beginning of a near century substantial investment in biomedical research. The NIH provides more financial support for medical research that any other agency in the world to date and claims responsibility for numerous innovations that have improved global health. The historical funding of biomedical research has undergone many changes over the past century. Innovations such as the polio vaccine, antibiotics and antipsychotic agents, developed in the early years of the NIH lead to social and political support of the agency. Political initiatives in the early 1990s lead to a doubling of NIH funding, spurring an era of great scientific progress. There have been dramatic changes in the era since the turn of the 21st century to date; roughly around the start of the century, the cost of trials dramatically increased while the rate scientific discoveries did not keep pace.
Biomedical research spending increased substantially faster than GDP growth over the past decade in the US, between the years of 2003 and 2007 spending increased 14% per year, while GDP growth increased 1% over the same period (both measures adjusted for inflation).Industry, not-for-profit entities, state and federal funding spending combined accounted for an increase in funding from $75.5 billion in 2003 to $101.1 billion in 2007. Due to the immediacy of federal financing priorities and stagnant corporate spending during the recession, biomedical research spending decreased 2% in real terms in 2008. Despite an overall increase of investment in biomedical research, there has been stagnation, and in some areas a marked decline in the number of drug and device approvals over the same time period.
Today, industry sponsored research accounts for 58% of expenditures, NIH for 27% of expenditures, state governments for 5% of expenditures, non NIH-federal sources for 5% of expenditures and not-for-profit entities accounted for 4% of support.Federally funded biomedical research expenditures increased nominally, 0.7% (adjusted for inflation), from 2003 to 2007. Previous reports showed a stark contrast in federal investment, from 1994 to 2003, federal funding increased 100% (adjusted for inflation).
The NIH manages the lions-share, over 85%, of federal biomedical research expenditures.NIH support for biomedical research decreased from $31.8 billion in 2003, to $29.0 billion in 2007, a 25% decline (in real terms adjusted for inflation), while non-NIH federal funding allowed for the maintenance of government financial support levels through the era (the 0.7% four-year increase). Spending from industry-initiated research increased 25% (adjusted for inflation) over the same time period of time, from 2003 to 2007, an increase from $40 billion in 2003, to $58.6 billion in 2007. Industry sourced expenditures from 1994 to 2003 showed industry sponsored research funding increased 8.1%, a stark contrast to 25% increase in recent years.
Of industry sponsored research, pharmaceutical firm spending was the greatest contributor from all industry sponsored biomedical research spending, but only increased 15% (adjusted for inflation) from 2003 to 2007, while device and biotechnology firms accounted for the majority of the spending.The stock performance, a measure that can be an indication of future firm growth or technological direction, has substantially increased for both predominantly medical device and biotechnology producers. Contributing factors to this growth are thought to be less rigorous FDA approval requirements for devices as opposed to drugs, lower cost of trials, lower pricing and profitability of products and predictable influence of new technology due to a limited number of competitors. Another visible shift during the era was a shift in focus to late stage research trials; formerly dispersed, since 1994 an increasingly large portion of industry-sponsored research was late phase trials rather than early-experimental phases now accounting for the majority of industry sponsored research. This shift is attributable to a lower risk investment and a shorter development to market schedule. The low risk preference is also reflected in the trend of large pharmaceutical firms acquiring smaller companies that hold patents to newly developed drug or device discoveries which have not yet passed federal regulation (large companies are mitigating their risk by purchasing technology created by smaller companies in early-phase high-risk studies). Medical research support from Universities increased from $22 billion in 2003 to $27.7 billion in 2007, a 7.8% increase (adjusted for inflation). In 2007 the most heavily funded institutions received 20% of HIN medical research funding, and the top 50 institutions received 58% of NIH medical research funding, the percent of funding allocated to the largest institutions is a trend which has increased only slightly over data from 1994. Relative to federal and private funding, health policy and service research accounted for a nominal amount of sponsored research; health policy and service research was funded $1.8 billion in 2003, which increased to $2.2 billion in 2008.
Stagnant rates of investment from the US government over the past decade, may be in part attributable to challenges that plague the field. To date only two-thirds of published drug trial findings have results that can be re-produced,which raises concerns from a US regulatory standpoint where great investment has been made in research ethics and standards, yet trial results remain inconsistent. Federal agencies have called upon greater regulation to address these problems; a spokesman from the National Institute of Neurological Disorders and Stroke, an agency of the NIH, stated that there is "widespread poor reporting of experimental design in articles and grant applications, that animal research should follow a core set of research parameters, and that a concerted effort by all stakeholders is needed to disseminate best reporting practices and put them into practice".
Two laws which are both still in effect, one passed in 2006 and the other in 2010, were instrumental in defining funding reporting standards for biomedical research, and defining for the first time reporting regulations that were previously not required. The 2006 Federal Funding Accountability and Transparency Act mandates that all entities receiving over $25,000 in federal funds must report annual spending reports, including disclosure of executive salaries.The 2010 amendment to the act mandates that progress reports be submitted along with financial reporting. Data from the federal mandate is managed and made publicly available on usaspending.gov. Aside from the main source, usaspending.gov, other reporting mechanisms exist: Data specifically on biomedical research funding from federal sources is made publicly available by the National Health Expenditure Accounts (NHEA), data on health services research, approximately 0.1% of federal funding on biomedical research, is available through the Coalition of Health Services Research, the Agency for Healthcare Research and Quality, the Centers for Disease Control and Prevention, the Centers for Medicare & Medicaid Services, and the Veterans Health Administration.
Currently there are not any funding reporting requirements for industry sponsored research, but there has been voluntary movement toward this goal.In 2014, major pharmaceutical stakeholders such as Roche and Johnson and Johnson have made financial information publicly available and Pharmaceutical Research and Manufacturers of America (PhRMA), the most prominent professional association for biomedical research companies, has recently begun to provide limited public funding reports.
Medical research is very highly regulated. National regulatory authorities are appointed in almost every country worldwide to oversee and monitor medical research, such as for the development and distribution of new drugs. In the US the Food and Drug Administration oversees new drug development, in Europe the European Medicines Agency (see also EudraLex), and in Japan the Ministry of Health, Labour and Welfare (Japan). The World Medical Association develops the ethical standards for the medical profession, involved in medical research. The most fundamental of them is the Declaration of Helsinki. The International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) works on the creation of rules and guidelines for the development of new medication, such as the guidelines for Good Clinical Practice (GCP). All ideas of regulation are based on a country's ethical standards code. This is why treatment of a particular disease in one country may not be allowed, but is in another.
A major flaw and vulnerability in biomedical research appears to be the hypercompetition for the resources and positions that are required to conduct science. The competition seems to suppress the creativity, cooperation, risk-taking, and original thinking required to make fundamental discoveries. Other consequences of today's highly pressured environment for research appear to be a substantial number of research publications whose results cannot be replicated, and perverse incentives in research funding that encourage grantee institutions to grow without making sufficient investments in their own faculty and facilities.Other risky trends include a decline in the share of key research grants going to younger scientists, as well as a steady rise in the age at which investigators receive their first funding.
After clinical research, medical therapies are typically commercialized by private companies such as pharmaceutical companies or medical device company. In the United States, one estimate found that in 2011, one-third of Medicare physician and outpatient hospital spending was on new technologies unavailable in the prior decade.
Medical therapies are constantly being researched, so the difference between a therapy which is investigational versus standard of care is not always clear, particularly given cost-effectiveness considerations.Payers have utilization management clinical guidelines which do not pay for "experimental or investigational" therapies, or may require that the therapy is medically necessary or superior to cheaper treatments. For example, proton therapy was approved by the FDA, but private health insurers in the United States considered it unproven or unnecessary given its high cost, although it was ultimately covered for certain cancers.
Fields of biomedical research include:
The Food and Drug Administration is a federal agency of the United States Department of Health and Human Services, one of the United States federal executive departments. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco 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. As of 2017, 3/4th of the FDA budget is paid by people who consume pharmaceutical products, due to the Prescription Drug User Fee Act.
The National Institutes of Health (NIH) is the primary agency of the United States government responsible for biomedical and public health research. It was founded in the late 1870s and is now part of the United States Department of Health and Human Services. The majority of NIH facilities are located in Bethesda, Maryland. The NIH conducts its own scientific research through its Intramural Research Program (IRP) and provides major biomedical research funding to non-NIH research facilities through its Extramural Research Program.
The American Psychiatric Association (APA) is the main professional organization of psychiatrists and trainee psychiatrists in the United States, and the largest psychiatric organization in the world. Its some 37,800 members are mainly American but some are international. The association publishes various journals and pamphlets, as well as the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM codifies psychiatric conditions and is used worldwide as a guide for diagnosing disorders.
Prescription drug prices in the United States have been among the highest in the world. The high cost of prescription drugs became a major topic of discussion in the new millennium, leading up to the U.S. health care reform debate of 2009, and received renewed attention in 2015. High prescription drug prices have been attributed to government-granted monopolies to manufacturers and organizations lacking ability to negotiate prices.
The National Center for Complementary and Integrative Health (NCCIH) is a United States government agency which explores complementary and alternative medicine (CAM). It was initially created as the Office of Alternative Medicine (OAM), and renamed the National Center for Complementary and Alternative Medicine (NCCAM) before receiving its current name. NCCIH is one of the 27 institutes and centers that make up the National Institutes of Health (NIH) within the Department of Health and Human Services of the federal government of the United States.
The pharmaceutical industry discovers, develops, produces, and markets drugs or pharmaceutical drugs for use as medications to be administered to patients, with the aim to cure them, vaccinate them, or alleviate the symptoms. Pharmaceutical companies may deal in generic or brand medications and medical devices. They are subject to a variety of laws and regulations that govern the patenting, testing, safety, efficacy and marketing of drugs.
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. Chelation therapy has a long history of use in clinical toxicology and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks.
The Wellcome Trust is a biomedical research charity based in London, United Kingdom. It was established in 1936 with legacies from the pharmaceutical magnate Sir Henry Wellcome to fund research to improve human and animal health. The aim of the Trust is to "achieve extraordinary improvements in health by supporting the brightest minds", and in addition to funding biomedical research it supports the public understanding of science. It has an endowment of £25.9 billion (2018) making it the third wealthiest charitable foundation in the world, after the Bill & Melinda Gates Foundation and the INGKA Foundation.
Research funding is a term generally covering any funding for scientific research, in the areas of both "hard" science and technology and social science. The term often connotes funding obtained through a competitive process, in which potential research projects are evaluated and only the most promising receive funding. Such processes, which are run by government, corporations or foundations, allocate scarce funds.
A serious adverse event (SAE) in human drug trials is defined as any untoward medical occurrence that at any dose
In health care, a clinical trial is a comparison test of a medication or other medical treatment, versus a placebo, other medications or devices, or the standard medical treatment for a patient's condition.
Medical ghostwriters are employed by pharmaceutical companies and medical-device manufacturers to produce apparently independent manuscripts for peer-reviewed journals, conference presentations and other communications. Physicians and other scientists are paid to attach their names to the manuscripts as though they had authored them. The named authors may have had little or no involvement in the research or writing process.
The Physician Payments Sunshine Act is a 2010 United States healthcare law to increase transparency of financial relationships between health care providers and pharmaceutical manufacturers.
AllTrials is a project advocating that clinical research adopt the principles of open research. The project summarizes itself as "All trials registered, all results reported": that is, all clinical trials should be listed in a clinical trials registry, and their results should always be shared as open data.
The Pediatric Trials Network (PTN) is a consortium of clinical research sites located around the United States that are cooperating in the design and conduct of clinical trials to improve health care for young patients. The network is sponsored by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).
Clinical trials can be promoted and funded by a variety of sponsors, including pharmaceutical companies, government, research charities, foundations, medical organizations, and voluntary groups, such as patients' associations.
Conflict of interest in the health care industry occurs when the primary goal of protecting and increasing the health of patients comes into conflict with any other secondary goal, especially personal gain to healthcare professionals, and increasing revenue to a healthcare organization from selling health care products and services. The public and private sectors of the medical-industrial complex have various conflicts of interest which are specific to these entities.
The US carries out 46% of global research and development (R&D) in life sciences, making it the world leader.
