Levels of Containment against a Biohazardous Agent

BayBiotech.NET
As per definition of Office of Health and Safety, “containment" is a term used for describing safe methods for managing infectious materials in the laboratory environment where they are being handled or maintained.
The main objective of containment is to reduce or eliminate exposure of laboratory workers, other persons, and the outside environment to potentially hazardous agents.
Two levels of containment defined are Primary and Secondary containment. Whereas, primary containment refers to the protection of personnel and the immediate laboratory environment from the infectious agents, the secondary containment refers to the protection of the environment external to the laboratory from the exposure to the infectious agent/ material.
Primary containment is provided by good microbiological techniques and use of appropriate safety equipments. Secondary containment is provided mainly by a combination of facility design and operational procedures.
A combination of risk assessment for a specific infectious agent, good practices, use of safety equipments and facility design will provide appropriate containment.

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.

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...

Risk Based Clinical Monitoring

BayBiotech.NET FDA's recommendation of Risk Based Monitoring of Clinical Trials , as published in their Draft Guidance in August 2011. For the first time, FDA provided guidance on monitoring of clinical investigations in 1988 which was recently withdrawn, stated that the “most effective way” to monitor an investigation was to “maintain personal contact between the monitor and the investigator throughout the clinical investigation.” At the time the guidance was issued, sponsors had only limited ways to effect meaningful communication with investigators other than through on-site visits.   This guidance recommends an assessment by the sponsor for the need of 100% on-site monitoring. Such an assessment may be based on the complexity of the study protocol and not be generally applicable to all trial types. It explains the importance of remote monitoring facilitated by the use of electronic data capture system (EDC) and also emphasizes the need of the identifying crit...
