Conduct presentations, distribute information, meet with current and potential scientists, make a splash with new drug developments, and receive named recognition at this 2-days event.
World-Renowned Speakers, the most recent techniques, developments, and the newest updates in Pharmacovigilance are Hallmarks of this Conference. Due to the higher medical needs and increasing disease prevalence, developing countries are becoming a hub for clinical trial execution. The clinical trials market has been estimated to reach USD Whether started by industry or by scholastic clinical examiners and research is frequently performed in national, European and overall consortia, which can be expansive ones. Clinical research brings up moral and security issues. To encourage and coordinated efforts crosswise over fringes.
Incidence of death due to ADRs is unknown; suggested rates of 0. Incidence and severity of adverse drug reactions vary by patient characteristics eg, age, sex, ethnicity, coexisting disorders, genetic or geographic factors and by drug factors eg, type of drug, administration route, treatment duration, dosage, and bioavailability.
Incidence is higher with advanced age and polypharmacy. Monitoring unlicensed, off labels and orphan drugs is major task in risk management. Also it is important to concentrate on Signal investigation by gathering the information on new or unknown drug effects that is potentially caused by a medicine and that finally should lead to ensuring safety. Pharmacy practice is the field of pharmacy which involves developing the professional roles of pharmacists.
Good data quality management in pharmacovigilance can be relied only on information gathered from the collection of individual case safety reports and other pharmacoepidemiological data. Quality management consists of quality planning, quality control, quality assurance and quality improvements. The pharmacovigilance data processing cycle starts with data collection and, in computerised systems, data entry; the next step is data storage and maintenance; followed by data selection, retrieval and manipulation. The resulting data output is analysed and assessed.
Finally, conclusions are drawn and decisions are made. Close examination, however, demonstrates the strong patient safety and advocacy responsibility of nurses who work in the pharmaceutical industry. Drug safety requires ongoing monitoring and surveillance to protect consumer safety.
PV at C3i Solutions support companies in the pharmaceutical industry as they monitor the safety profiles of their products and report safety information to regulatory authorities both in the US and globally. Our PV Team consistently monitors the regulatory landscape to ensure that the drug safety reporting that we do is in compliance with the most up to date regulatory intelligence. For example, in March, , the FDA issued guidance known as the Final Rule , which indicated that a pharmaceutical company should have evidence suggesting causality of the event to a drug or device before expediting a report to the FDA.

The non-expedited reports are presented in an aggregate format for review by the FDA. The reality is that regulatory authorities want to make reporting of safety information as easy as possible and a mixed method of surveillance is most effective. In the US, the FDA uses both passive and active surveillance to overcome the obstacles of under-reporting of events. Passive surveillance is voluntary reporting of adverse events.
These reports come into an electronic database from HCPs, manufacturers, and patients for review and assessment. At the same time, the FDA also does active surveillance called the Sentinel Initiative , which uses data from multiple sources to assess the safety of approved products. In this initiative, data mining and outreach through electronic health records and health claims is utilized to identify and assess adverse events while protecting the privacy and data security of patients.
In addition, the FDA and other global regulatory authorities continuously monitor safety reporting processes to provide guidelines like the Final Rule that help to encourage and streamline reporting.
As technology continues to change, the industry has also expanded surveillance into areas such as social media to ensure that events discussed in this arena are not missed. In conjunction with the regulatory authorities, the industry encourages the reporting of events through as many avenues as possible. ADE vs.
ADR e intensity e. Objectivity refers to adverse reactions that are measured primarily in numerical or objective terms e. It may be pseudo-quantitative e. In these trials, critical efficacy endpoints are identified in advance and sample sizes are estimated for an adequate assessment of effectiveness. In contrast, with few exceptions, phase trials are not designed to test specified hypotheses about safety nor to measure or identify adverse reactions with any pre-specified level of sensitivity. The exceptions occur when a particular concern related to the drug or drug class has arisen and when there is a specific safety advantage being studied.
In these cases, there will often be safety studies with primary safety endpoints that includes all the features of hypothesis testing, including blinding, control groups, and pre-specified statistical plans 6.
Drug Safety and Pharmacovigilance in Clinical Practice
Since safety of the subject is of utmost importance in a clinical trial, it is necessary to determine whether the subject is fit for the trial or not. For this, investigation brochure IB findings are applied to the protocol and a prospective subject. Pharmacology of the drug or pharmacologically related drugs can be useful in the identification and exploration of major safety concerns. For example, the clearance pathway of a drug can be indicative of certain potential drug-drug interactions or certain effects of decreased renal or hepatic function.
Similarly, the pharmacologic class, and prior experience, could lead to focus on particular laboratory or clinical abnormalities e. Unexpected fatal or life-threatening suspected adverse reactions represent especially important safety information and, therefore, must be reported more rapidly to FDA. If the safety report submitted within 7 calendar days is complete, an additional submission within 15 days from day zero is not required. The sponsor must also report expeditiously any findings from clinical, epidemiological, or pooled analysis of multiple studies or any findings from animal or in vitro testing that suggest a significant risk in humans exposed to the drug e.
Any relevant additional information that the sponsor obtains that pertains to a previously submitted IND safety report must be submitted as a Follow-up IND Safety Report without delay, as soon as the information is available, but should be submitted no later than 15 calendar days after the sponsor receives the information.
The IND annual safety reporting is required of all IND holders and should include most frequent and most serious AEs by body system, list of subjects who died, including cause and list of subjects who dropped out in association with an adverse experience. The occurrence of a serious adverse event is very unusual because the number of subjects enrolled in such a study is small, subjects are usually healthy volunteers, and drug exposure is typically brief. However, FDA occasionally receives safety-related information associated with these types of studies, which could reflect either a problem with the drug product being evaluated or with the study design being used.
For these reasons, the occurrence of any serious adverse event, whether or not it is considered drug related, is of interest. Timely review of this safety information is critical to ensuring the safety of study subjects. FDA recommends that 7-day notifications be made by telephone, email, or facsimile transmission. If the safety report submitted within 7 calendar days is complete, an additional submission within 15 days from day zero is not required 3. An inherent problem in pharmacovigilance is that most case reports concern suspected adverse drug reactions.
Adverse reactions are rarely specific for the drug, diagnostic tests are usually absent and a rechallenge is rarely ethically justified. Statistical analysis can lead to structured and harmonized assessment of causality by decreasing disagreement between assessors, classifying relationship likelihood, marking individual case reports and improvement of scientific evaluation.
It can be particularly useful for evaluation of common adverse events. Causality assessment can be performed simply by categorizing evidence by the quality of its sources and evaluating the evidence of a causal relationship using standard guidelines. Various sources for causality assessment can be clinical trials, cohort or case-control studies, time-series studies and case-series. Use of standard guidelines for evaluating the evidence of a causal relationship may include a temporal relationship b strength of association, c dose-response relationship d replication of findings e biologic plausibility f consideration of alternate explanations g cessation of exposure h specificity of the association and i consistency with other knowledge.
FDA approves a product when it judges that the benefits of using a product outweigh the risks for the intended population and use. A major goal of the premarketing review is to ensure that products are truthfully and adequately labeled for the population and use.
Labeling is given considerable emphasis because it is the chief tool the Agency uses to communicate risk and benefit to the healthcare community and patients. Once medical products are on the market, however, ensuring safety is principally the responsibility of healthcare providers and patients, who make risk decisions on an individual, rather than a population, basis. They are expected to use the labeling information to select and use products wisely, thereby minimizing adverse events.
To assist with post marketing risk management, the Agency maintains a system of complex post marketing surveillance and risk assessment programs to identify adverse events that are not identified during medical product development and premarketing review. FDA monitors suspected adverse events associated with the use of an approved medical product. The Agency uses this information to initiate labeling updates and, on rare occasions, to reevaluate the marketing decision 9 Fig.
Postmarketing surveillance PMS is the practice of monitoring the safety of a pharmaceutical drug or medical device after it has been released on the market and is an important part of the drug safety. Since drugs are approved on the basis of clinical trials, which involve relatively small numbers of people who normally do not have other medical conditions which may exist in the general population - postmarketing surveillance can further refine, or confirm or deny, the safety of a drug after it is used in the general population by large numbers of people who have a wide variety of medical conditions.
These data are reviewed to highlight potential safety concerns in a process known as data mining. For ensuring drug safety on long term and on a wider population, regulatory authorities ask the marketing authorization holders MAH for reporting of AEs and periodic submission of safety reports. For serious and unexpected AEs, FDA recommends reports to be submitted within 15 calendar days either foreign or domestic. A Follow-up to day alert reports should be submitted within 15 calendar days. Safety reports are pharmacovigilance documents intended to provide an evaluation of the risk-benefit balance of a medicinal product for submission by marketing authorisation holders at defined time points during the postauthorisation phase.
In USA, periodic adverse drug experience reports PADER are submitted quarterly within 30 calendar days of the data lock point day 0 for 3 years from date of approval, then annually within 60 calendar days of the data lock point day 0. The timeline for the submission of ad hoc PSURs requested by competent authorities are specified in the request, otherwise the ad hoc PSURs has to be submitted within 90 calendar days of the data lock point FDA recently adopted the guidance for industry E2F Development Safety Update Report , which describes a common standard for periodic reporting on drugs under development among the ICH regions and is intended to meet the IND annual reporting requirements.
C of this document. The Agency does not expect the IND safety reporting requirements to have any impact on the adverse reaction information presented in prescription drug labeling. Medical products today are developed and used within a complex system involving a number of key participants: 1 manufacturers who develop and test products and submit applications for their approval to the FDA; 2 the FDA, which has an extensive premarketing review and approval process and uses a series of post marketing surveillance programs to gather data on and assess risks; 3 other participants in the healthcare delivery system, including healthcare practitioners; and 4 patients, who rely on the ability of this complex system to provide them with needed interventions while protecting them from injury.
All participants in the medical product development and delivery system have a role to play in maintaining this benefit-risk balance by making sure that products are developed, tested, manufactured, labeled, prescribed, dispensed, and used in a way that maximizes benefit and minimizes risk. Medicinal products provide great benefit to the public, but same time they can also be harmful.
