FDA advisory committees and the new drug approval process.

To determine the impact of FDA advisory committee review on the approval time of new drug applications (NDAs) approved during the five-year period 1983 through 1987, we compared NDA phase lengths of reviewed new chemical entities (NCEs) with those that were not reviewed and examined the elapsed time from final committee recommendation for approval to NDA approval. Of the 95 drugs approved during the study period that met the Center for the Study of Drug Development's definition of an NCE, 40 (42%) were submitted for review--mean NDA phase length was 36.9 months versus 32.4 months for unreviewed drugs. Reviewed drugs in the neuropharmacologic division had a longer NDA phase, while those in the metabolic/endocrine and oncology/radiopharmaceutical divisions had shorter NDA phases, than unreviewed drugs in those divisions. For NCEs grouped by therapeutic rating, reviewed drugs in each category had longer NDA phases than unreviewed drugs; the difference was largest for 1-B rated drugs. The elapsed time from committee recommendation for approval to NDA approval as a percent of the total NDA phase was greatest for drugs submitted by the metabolic/endocrine division (83.0% of NDA phase) and for drugs rated 1-A (63.2%). Results indicate that advisory committee review is associated with a small overall delay in NDA approval when compared with the regulatory fate of drugs not submitted for review.

General recommendations on immunization: recommendations of the Advisory Committee on Immunization Practices (ACIP).

This report is a revision of General Recommendations on Immunization and updates the 2002 statement by the Advisory Committee on Immunization Practices (ACIP) (CDC. General recommendations on immunization: recommendations of the Advisory Committee on Immunization Practices and the American Academy of Family Physicians. MMWR 2002;51[No. RR-2]). This report is intended to serve as a general reference on vaccines and immunization. The principal changes include 1) expansion of the discussion of vaccination spacing and timing; 2) an increased emphasis on the importance of injection technique/age/body mass in determining appropriate needle length; 3) expansion of the discussion of storage and handling of vaccines, with a table defining the appropriate storage temperature range for inactivated and live vaccines; 4) expansion of the discussion of altered immunocompetence, including new recommendations about use of live-attenuated vaccines with therapeutic monoclonal antibodies; and 5) minor changes to the recommendations about vaccination during pregnancy and vaccination of internationally adopted children, in accordance with new ACIP vaccine-specific recommendations for use of inactivated influenza vaccine and hepatitis B vaccine. The most recent ACIP recommendations for each specific vaccine should be consulted for comprehensive discussion. This report, ACIP recommendations for each vaccine, and other information about vaccination can be accessed at CDC's National Center for Immunization and Respiratory Diseases (proposed) (formerly known as the National Immunization Program) website at http//:www.cdc.gov/nip.

The role of BCG vaccine in the prevention and control of tuberculosis in the United States. A joint statement by the Advisory Council for the Elimination of Tuberculosis and the Advisory Committee on Immunization Practices.

This report updates and replaces previous recommendations regarding the use of Bacillus of Calmette and Guerin (BCG) vaccine for controlling tuberculosis (TB) in the United States (MMWR 1988;37:663-4, 669-75). Since the previous recommendations were published, the number of TB cases have increased among adults and children, and outbreaks of multidrug-resistant TB have occurred in institutions. In addition, new information about the protective efficacy of BCG has become available. For example, two meta-analyses of the published results of BCG vaccine clinical trials and case-control studies confirmed that the protective efficacy of BCG for preventing serious forms of TB in children is high (i.e., > 80%). These analyses, however, did not clarify the protective efficacy of BCG for preventing pulmonary TB in adolescents and adults; this protective efficacy is variable and equivocal. The concern of the public health community about the resurgence and changing nature of TB in the United States prompted a re-evaluation of the role of BCG vaccination in the prevention and control of TB. This updated report is being issued by CDC, the Advisory Committee for the Elimination of Tuberculosis, and the Advisory Committee on Immunization Practices, in consultation with the Hospital Infection Control Practices Advisory Committee, to summarize current considerations and recommendations regarding the use of BCG vaccine in the United States. In the United States, the prevalence of M. tuberculosis infection and active TB disease varies for different segments of the population; however, the risk for M. tuberculosis infection in the overall population is low. The primary strategy for preventing and controlling TB in the United States is to minimize the risk for transmission by the early identification and treatment of patients who have active infectious TB. The second most important strategy is the identification of persons who have latent M. tuberculosis infection and, if indicated, the use of preventive therapy with isoniazid to prevent the latent infection from progressing to active TB disease. Rifampin is used for preventive therapy for persons who are infected with isoniazid-resistant strains of M. tuberculosis. The use of BCG vaccine has been limited because a) its effectiveness in preventing infectious forms of TB is uncertain and b) the reactivity to tuberculin that occurs after vaccination interferes with the management of persons who are possibly infected with M. tuberculosis. In the United States, the use of BCG vaccination as a TB prevention strategy is reserved for selected persons who meet specific criteria. BCG vaccination should be considered for infants and children who reside in settings in which the likelihood of M. tuberculosis transmission and subsequent infection is high, provided no other measures can be implemented (e.g., removing the child from the source of infection). In addition, BCG vaccination may be considered for health-care workers (HCWs) who are employed in settings in which the likelihood of transmission and subsequent infection with M. tuberculosis strains resistant to isoniazid and rifampin is high, provided comprehensive TB infection-control precautions have been implemented in the workplace and have not been successful. BCG vaccination is not recommended for children and adults who are infected with human immunodeficiency virus because of the potential adverse reactions associated with the use of the vaccine in these persons. In the United States, the use of BCG vaccination is rarely indicated. BCG vaccination is not recommended for inclusion in immunization or TB control programs, and it is not recommended for most HCWs. Physicians considering the use of BCG vaccine for their patients are encouraged to consult the TB control programs in their area.

Advisory Committee: A Powerful Tool for Helping Decision Makers inEnvironmental Issues

/ It has been suggested that the general public should be moreinvolved in environmental policy and decision making. It is important forthem to realize that they will have to live with the consequences ofenvironmental policies and decisions. Consequently, policy makers shouldconsider the concerns and opinions of the general public before makingdecisions on environmental issues. This raises questions such as: How can weintegrate the perceptions and reactions of the general population inenvironmental decisions? What kind of public participation should weconsider? In the present study, using a new regional ecosystem model, weattempted to integrate these aspects in its decision making model byincluding the formation of an advisory committee to resolve problems relatedto waste management. The advisory committee requested the activeparticipation of representatives from all levels of the community: economic,municipal, and governmental intervenors; environmental groups; and citizens.Their mandates were to examine different management strategies available inthe region, considering all the interdisciplinary aspects of each strategy,elaborate recommendations concerning the management strategies that are mostsuitable for all, and collaborate in communication of the information to thegeneral population. The results showed that at least in small municipalitiessuch an advisory committee can be a powerful tool in environmental decisionmaking. Conditions required for a successful consultation process, such aseveryday lay language and the presence of a facilitator other than ascientific expert, are discussed.KEY WORDS: Public consultation; Environmental policies;Interdisciplinary aspects; Municipal sewage sludge management; Generalpopulation; Decision-making process

A seat at the table: membership in federal advisory committees evaluating public policy in genetics.

OBJECTIVES: This study examined who participates in federal government advisory committees regarding public policy in human and medical genetics, what parties they represent, and to what extent the general public is meaningfully represented. METHODS: Analysis focused on 7 federal government documents published from January 1990 to February 1995. Advisors were categorized into 4 groups based on the professional affiliations that were listed in the publications. After a search of several references and data-bases, the study examined whether these individuals also had other affiliations not listed in the government publications. RESULTS: Individuals whose principal affiliations were with academia (n = 32; 44%) or industry (n = 19; 26%) represented nearly three fourths of the sample, followed by government employees (n = 13; 18%) and consumer advocates (n = 8; 11%). At least 16% of the advisors serving on the federal committees, mostly members of academia, had a dual affiliation. CONCLUSIONS: These data indicate that the public has modest representation on key federal advisory committees making policy recommendations regarding human genetics technology and clinical practice and that there is ample room for additional public participation.

Update: vaccine side effects, adverse reactions, contraindications, and precautions. Recommendations of the Advisory Committee on Immunization Practices (ACIP)

This report provides updated information concerning the potential adverse events associated with vaccination for hepatitis B, poliomyelitis, measles, mumps, diphtheria, tetanus, and pertussis. This information incorporates findings from a series of recent literature reviews, conducted by an expert committee at the Institute of Medicine (IOM), of all evidence regarding the possible adverse consequences of vaccines administered to children. This report contains modifications to the previously published recommendations of the Advisory committee on Immunization Practices (ACIP) and is based on an ACIP review of the IOM findings and new research on vaccine safety. In addition, this report incorporates information contained in the "Recommendations of the Advisory Committee on Immunization Practices: Use of Vaccines and Immune Globulins in Persons with Altered Immunocompetence" (MMWR 1993;42[No. 44-4]) and the "General Recommendations on Immunization: Recommendations of the Advisory Committee on Immunization Practices (ACIP)" (MMWR 1994;43[No. RR-1]). Major changes to the previous recommendations are highlighted within the text, and specific information concerning the following vaccines and the possible adverse events associated with their administration are included: hepatitis B vaccine and anaphylaxis, measles vaccine and a) thrombocytopenia and b) possible risk for death resulting from anaphylaxis or disseminated disease in immunocompromised persons; diphtheria and tetanus toxoids and pertussis vaccine (DTP) and chronic encephalopathy; and tetanus-toxoid-containing vaccines and a) Guillain-Barre syndrome, b) brachial neuritis, and c) possible risk for death resulting from anaphylaxis. These modifications will be incorporated into more comprehensive ACIP recommendations for each vaccine when such statements are revised. Also included in this report are interim recommendations concerning the use of measles and mumps vaccines in a) persons who are infected with human immunodeficiency virus and b) persons who are allergic to eggs; ACIP is still evaluating these recommendations.

A global perspective on vaccine safety and public health: the Global Advisory Committee on Vaccine Safety.

Established in 1999, the Global Advisory Committee on Vaccine Safety advises the World Health Organization (WHO) on vaccine-related safety issues and enables WHO to respond promptly, efficiently, and with scientific rigor to issues of vaccine safety with potential global importance. The committee also assesses the implications of vaccine safety for practice worldwide and for WHO policies. We describe the principles on which the committee was established, its modus operandi, and the scope of the work undertaken, both present and future. We highlight its recent recommendations on major issues, including the purported link between the measles-mumps-rubella vaccine and autism and the safety of the mumps, influenza, yellow fever, BCG, and smallpox vaccines as well as that of thiomersal-containing vaccines.

Poliomyelitis prevention in the United States. Updated recommendations of the Advisory Committee on Immunization Practices (ACIP).

These recommendations of the Advisory Committee on Immunization Practices (ACIP) for poliomyelitis prevention replace those issued in 1997. As of January 1, 2000, ACIP recommends exclusive use of inactivated poliovirus vaccine (IPV) for routine childhood polio vaccination in the United States. All children should receive four doses of IPV at ages 2, 4, and 6-18 months and 4-6 years. Oral poliovirus vaccine (OPV) should be used only in certain circumstances, which are detailed in these recommendations. Since 1979, the only indigenous cases of polio reported in the United States have been associated with the use of the live OPV. Until recently, the benefits of OPV use (i.e., intestinal immunity, secondary spread) outweighed the risk for vaccine-associated paralytic poliomyelitis (VAPP) (i.e., one case among 2.4 million vaccine doses distributed). In 1997, to decrease the risk for VAPP but maintain the benefits of OPV, ACIP recommended replacing the all-OPV schedule with a sequential schedule of IPV followed by OPV. Since 1997, the global polio eradication initiative has progressed rapidly, and the likelihood of poliovirus importation into the United States has decreased substantially. In addition, the sequential schedule has been well accepted. No declines in childhood immunization coverage were observed, despite the need for additional injections. On the basis of these data, ACIP recommended on June 17, 1999, an all-IPV schedule for routine childhood polio vaccination in the United States to eliminate the risk for VAPP. ACIP reaffirms its support for the global polio eradication initiative and the use of OPV as the only vaccine recommended to eradicate polio from the remaining countries where polio is endemic.

Geographic distribution of physician manpower: the GMENAC (Graduate Medical Education National Advisory Committee) legacy.

The Graduate Medical Education National Advisory Committee (GMENAC) projected the need for and supply of physicians and other providers, recommended time and access standards for health care services, and developed guidelines for the geographic distribution of physicians. Since this study, analysts have given scant attention to national problems of physician geographic distribution. The issue deserves additional scrutiny in light of the current continuing problems of underservice in rural areas. The emergence of geographic information systems offers a unique opportunity to acquire data on provider distribution and provide a framework for developing and testing redistribution policy.
