Notice of public workshop.
The Food and Drug Administration (FDA) is announcing the following meeting: “Public Workshop on Burkholderia: Exploring Current Issues and Identifying Regulatory Science Gaps.” An interagency planning committee led by FDA, in collaboration with the Defense Threat Reduction Agency; the National Institute of Allergy and Infectious Diseases, a component of the National Institutes of Health; the Centers for Disease Control and Prevention; the U.S. Army Medical Research Institute of Infectious Diseases; the Biomedical Advanced Research and Development Authority; the Chemical Biological Medical Systems Joint Project Management Office; the U.S. Strategic Command Center for Combating Weapons of Mass Destruction; and the Joint Science and Technology Office for Chemical and Biological Defense, developed this workshop to present the most current information on melioidosis (caused by Burkholderia pseudomallei) and glanders (caused by B. mallei), with the general purpose of building on information presented at previous meetings and identifying future areas of research needed to advance animal model development and to advance candidate medical countermeasures (MCMs) for approval, licensure, or clearance.
This public workshop will be held on Thursday, November 29, 2012, from 8 a.m. EST to 5 p.m. EST, and Friday, November 30, 2012, from 8 a.m. EST to 12 noon EST. Persons interested in attending the workshop in person or viewing via Webcast must register by Wednesday, November 21, 2012, at 5 p.m. EST.
The public workshop will be held at FDA White Oak Campus, 10903 New Hampshire Ave., Bldg. 31 Conference Center, the Great Room (Rm. 1503A), Silver Spring, MD 20993-0002. Information regarding special accommodations due to a disability, visitor parking, and transportation may be accessed at: http://www.fda.gov/AdvisoryCommittees/default.htm; under the heading “Resources for You,” click on “Public Meetings at the FDA White Oak Campus.” Please note that visitors to the White Oak Campus must enter through Building 1.

B. pseudomallei is a gram-negative bacterial pathogen that causes melioidosis, a disease endemic in Southeast Asia and northern Australia. Melioidosis is historically associated with a high mortality rate due to the speed with which septicemia develops and the inherent resistance of the bacteria to several classes of antibiotics. For example, a 20-year prospective study of melioidosis in northern Australia found an overall mortality of 14 percent and a 50 percent mortality rate for patients with septic shock (Ref. 1). A 9-year prospective study of melioidosis in northeast Thailand found an overall mortality rate of 42.6 percent (Ref. 2). Prolonged courses of antibiotics are required to treat melioidosis (Ref. 3). Despite prolonged antimicrobial therapy, recurrent disease is common (at a rate of greater than or equal to 6 percent in the first year) (Refs. 1 and 4). In addition to the public health threat posed by naturally occurring infections, B. pseudomallei has been determined to pose a material threat sufficient to affect the United States' national security (Ref. 5).
B. mallei (formerly Pseudomonas mallei) is a gram-negative, bacterial pathogen that causes glanders and is primarily a zoonotic disease in Africa, Asia, the Middle East, and Central/South America. Natural glanders infections occur primarily in horses, donkeys, and mules, but most mammals have some degree of susceptibility. While human susceptibility to B. mallei infection has not been studied indepth, the organism is highly infectious in the laboratory setting. Prolonged antimicrobial therapy is required to treat B. mallei infection and prevent its relapse (Refs. 6 and 7). B. mallei has also been determined to pose a material threat sufficient to affect the United States' national security (Ref. 5).
Because of the lengthy antibiotic therapy required to treat melioidosis and glanders and the suboptimal clinical outcomes, lack of vaccines, possible biothreat applications, and public health implications, there is significant interest in developing new MCMs as well as improved animal models to evaluate candidate MCMs for these diseases. This public workshop was designed with specific goals that include, but are not limited to:
- Review of the current state of the knowledge of human melioidosis and glanders;
- Discussion of the availability of relevant animal models and their current state of development;
- Discussion of the availability, development, procurement, and stockpiling of relevant MCMs, including diagnostic tests; and
- Identification of the scientific and regulatory considerations associated with testing and development of MCMs for safe and effective treatment or prevention of these diseases.
II. How to Register
