However the act was considered inactivated because. False statements made about a drug by a manufacturer were held by the courts not to be misbranding. Sulfanilamide, a drug used to treat streptococcal infections, had been shown to have dramatic curative effects and had been used safely for some time in tablet and powder form.
Experiments showed that sulfanilamide would dissolve in diethylene glycol. No pharmacological studies had been done on the new sulfanilamide preparation and so there was a failure to note one characteristic of the solution. Diethylene glycol, a chemical normally used as antifreeze, is a deadly poison.
This preparation took lives of more than people in 15 states 4. The drug and the deaths led to the passage of the Food, Drug, and Cosmetic Act, which increased FDA's authority to regulate drugs. Among other things, this law required new drugs to be tested for safety before marketing, the results of which would be submitted to FDA in a new drug application NDA.
The law also required that drugs have adequate labeling for safe use. All drug advertising was assigned to the Federal Trade Commission.
The term label is a term of art. The law requires that if certain information is required to be on the label of a drug, the information must also be on the outer or the inner label clearly visible through such outer wrapper. This new label, in addition to require proof of safety, expanded the meaning of adulteration and misbranding that previously had been strictly enforced by the law.
Labels were now required to provide adequate directions for use to the consumer 5. Durham — Humphrey Amendment of exempted certain drugs from the requirement that their labelling contains adequate direction for use.
The act was amended to formally distinguish between prescription and over the counter drugs. Until that time all drugs could be purchased over the counter by the consumers. Prescription drugs were required to contain the warning that the drugs could be dispensed legally only with the authorisation of a health professional 6.
Nuremberg code includes ten principles to guide physician investigators in experiments involving human subjects. These principles, particularly the first principles on voluntary consent, primarily were based on legal concepts because medical codes of ethics existence at the time of the Nazi atrocities did not address consent and other safeguards for human subjects.
The need to define the basic principles for the conduct of human research was focused on the patient protection and made no distinction between research with patient subjects and healthy persons, be there prisoners or volunteers. In Germany Nuremberg code is regarded as a guideline for medical research. Many of the principles are still valid today.
That is the necessity of informed consent, the rule that the patient can withdraw from the experiment at any time and the ban against experimentation that in any way could result in major injury or death of the experimental subject.
The ten principles of Nuremberg are rarely applied now-a-days. Its due mostly to the fact that they do not distinguish between therapeutic and purely scientific experiments and that there have been super seated by the revised declaration of Helsinki of the World Medical Association. In , thalidomide, a sleeping pill developed and widely used abroad, was being studied for use in the United States.
William S Merrell Company of Cincinnati was using the drug investigationally when it was discovered that the drug could harm the foetus when taken by a pregnant women during the first trimester of pregnancy.
Children born to such mothers often were born without arms or other severe deformities. It was clear that people were taking drugs and neither the prescriber nor the manufacturer had a clear knowledge of the effects 8 9. Under these circumstances the Durham Humfrey amendment was simply inadequate to protect the public. The series of law suits demonstrated that large prescribers are relying on manufactures for the information about the drugs and that information in some instances had been based on inadequate testing.
This resulted in Kefauver — Harris Amendments of which addressed the issue of effectiveness and safety Good Clinical Practice GCP is an international ethical and scientific quality standard for designing, conducting, recording and reporting trials that involve the participation of human subjects.
Compliance with this standard provides public assurance that the rights, safety and well-being of trial subjects are protected, consistent with the principles that have their origin in the Declaration of Helsinki, and that the clinical trial data are credible. This guideline should be followed when generating clinical trial data that are intended to be submitted to regulatory authorities.
The principles established in this guideline may also be applied to other clinical investigations that may have an impact on the safety and well-being of human subjects. Evolutions in technology and risk management processes offer new opportunities to increase efficiency and focus on relevant activities. When the original ICH E6 R1 text was prepared, clinical trials were performed in a largely paper-based process.
Advances in use of electronic data recording and reporting facilitate implementation of other approaches. Each individual involved in conducting a trial should be qualified by education, training, and experience to perform his or her respective task s. Freely given informed consent should be obtained from every subject prior to clinical trial participation.
All clinical trial information should be recorded, handled, and stored in a way that allows its accurate reporting, interpretation and verification. The confidentiality of records that could identify subjects should be protected, respecting the privacy and confidentiality rules in accordance with the applicable regulatory requirement s.
Investigational products should be manufactured, handled and stored in accordance with applicable Good Manufacturing Practice GMP. They should be used in accordance with the approved protocol. Systems with procedures that assure the quality of every aspect of the trial should be implemented.
All clinical trials should be conducted in accordance with ethical principles, sound scientific evidence and clear detailed protocols. The benefits of conducting trials should outweigh the risks. The rights, safety and well-being of trial participants are of paramount importance and these should be preserved by obtaining informed consent and maintaining confidentiality.
The care must be given by appropriately qualified personnel with adequate experience. Records should be easily accessible and retrievable for accurate reporting, verification and interpretation.
Investigational products should be manufactured according to Good Manufacturing Practice 8. It is also important to mention the participants of GCP in clinical trials and their respective responsibilities. These are summarised in Table 3. Since the conception of the ICH-GCP guidelines, many countries in the Asia-Pacific region realised the need to formulate guidelines of their own based on the framework of the original guidelines [ 7 ].
This is clearly seen in Table 4 that tabulates the adoption of GCP in our country and its neighbours. In Malaysia, similar guidelines were formulated in the wake of greater demand by the pharmaceutical industry to conduct clinical trials in the country. To know the answer to this, we have to look to the historical background that led to the formulation of GCP guidelines in the United States and Europe and also to the formation of the ICH. The events that led up to the culmination of the ICH-GCP guidelines brought forth public awareness that there was a need to control and regulate clinical trials dealing with drugs and human subjects.
The violation of human rights played a large role and that is why the Declaration of Helsinki and The Nuremberg Code remain as the framework of the present guidelines. National Center for Biotechnology Information , U. Biomed Imaging Interv J. Published online Jan 1. However, at trial they argued that there was in fact no law in place or even an informal statement suggesting that this experimenting should not be carried out. After these trials, and in order to protect the rights of the individual taking part in research, two American Doctors, who had been present in Nuremberg, devised a list of 10 points defining how valid and legitimate research should be conducted.
The key points of this code indentified and prioritised the rights of the individual and included, for the first time in an international document, such principles as voluntary participation, informed consent and allowing the participant to withdraw from the experiment at any time.
It also suggested that measures should be taken in order minimise any risk to the participant, and that the benefits of the research should outweigh the potential risks. In the World Medical Association, which had formed in to address in particular the non clinical issues that Physicians might be faced with, enhanced the points highlighted in the Nuremberg Code and created a more formal statement of ethical principles. Its purpose was to provide specific guidance to physicians, and any other interested participants, who work in any medical research that involves human subjects.
The Declaration of Helsinki has itself been updated and revised several times over the past 47 years, the latest being in This in turn led to delays in getting the product to market and created an increase in the costs to the pharmaceutical industry. The solution to this problem came about in when a series of conferences were held in order to unify the differing codes of practice. All parties from various countries agreed to follow the same code of good practice, leading to an internationally recognised, uniform standard to which all countries could commit.
It provides guidance on such issues as.
