Good Pharmacovigilance Practices (GPPs)

BayBiotech.NET
Pharmacovigilance is a branch that involves the identification and evaluation of safety signals generated by the usage of a medical product.

Safety Signal: is a concern raised when excess of adverse events are observed compared
to what would be expected with a product's use. Signals can arise from collection of post marketing data, preclinical data and events associated with other products in the same pharmacologic class.

Even a single well-documented case report can be viewed as a signal, particularly if the report describes an event that is extremely rare in the absence of drug use.

Signals indicate the need for further investigation, which may or may not lead to the conclusion that the product caused the event.

After a signal is identified, it should be further assessed to determine whether it represents
a potential safety risk and whether other action should be taken.

Good Pharmacovigilance Practice is based on acquiring complete data from
spontaneous adverse event reports, also known as case reports.

In order to understand and interpret the adverse events, good and well documented reports are emphasized following Good Reporting Practice guidelines:

Good Reporting Practices

A good and well documented Case reports of adverse events submitted to the sponsor and FDA, as well as reports from the medical literature or clinical studies, may generate signals of adverse effects of drugs.

A good quality report is critical for appropriate evaluation of the adverse events caused by the usage of the product.

FDA recommends that reasonable attempts be made to obtain complete information for case assessment during initial contacts and subsequent follow-up, especially for serious events.

Sponsors may use trained and well informed health care practitioners to query reporters.

Computer-assisted interview technology, targeted questionnaires, or other methods developed to target specific events can help focus the line of questioning.

When the report is from a consumer, it is often important to obtain permission to
contact the health care practitioner familiar with the patient’s adverse event to obtain further
medical information and to retrieve relevant medical records, as needed.

It is further recommended that the most aggressive follow-up efforts be directed towards serious
adverse event reports, especially of adverse events not known to occur with the drug.

Amendments for High Risk Device Type Regulatory Pathway

BayBiotech.NET Government Accounting Office (“GAO”) has issued a long-awaited report evaluating the use of the 510(k) process by the Food and Drug Administration (“FDA” or the “Agency”) in the January of 2009. Report mainly focused on Preamendment class III devices. Although most high-risk class III medical devices are subject to the demanding premarket approval (“PMA”) process, preamendment class III devices may be cleared through the 510(k) pathway until FDA issues regulations requiring a PMA. Under the Safe Medical Devices Act of 1990, FDA was required either to reclassify preamendment class III devices into class I or II, or (2) issue regulations requiring PMA approval for the devices, GAO noted that 20 preamendment class III device types have not yet been addressed by the Agency. GAO has urged FDA to take required steps to address the remaining class III devices that continue to be eligible for 510(k) review. As a result of the report, FDA has committed to address al...

Harmonization by Doing (HBD): Japan & U.S. Collaboration

BayBiotech.NET HBD is an international cooperative effort by Japan and US for regulatory convergence for Medical Devices. The efforts are focused on to develop global clinical trials and address regulatory barriers for timely device approvals. To address the needs for additional evaluation, the HBD initiative is a pilot project launched jointly by FDA and MHLW-PMDA for the premarket review of device cardiovascular technology. Instead of taking a theoretical approach to harmonization, HBD is focused on Proof of concept by utilizing parallel development, application submissions and review of actual medical device projects. HBD Study intends to collect and analyze regulatory submission data from multiple applications in the U.S. and Japan. The purpose of the study is to further understand differences that may exist with format and content, to define best practices and to improve globally harmonized processes.

510(k) Summary or Statement

BayBiotech.NET A premarket notification from a manufacturer must include either a summary of the 510(k) safety and effectiveness information of the product upon which the substantial-equivalence determination is based or a statement that this information will be made available by the 510(k) applicant to any person within 30 days of a written request. As per FDA definition, these are the definition of Summary and Statements: Summaries are released by FDA regarding a 510(k) clearance when requested under the Freedom of Information (FOI) Act whereas Statements are used to arrange for this FOI request to be fulfilled by the 510(k) applicant. 510(k) Summaries: If a summary is included, it must be submitted with the 510(k) notification as per FDA guidelines. The summary must be complete and correct in order for FDA to complete its review of a 510(k) submission. FDA will accept summaries and amendments until it issues a determination of substantial equivalence. If a summary has be...
