EXPLANATION OF PROGRAM

American consumers rely on the FDA to improve health by ensuring that safe and effective medicines are available and that unsafe or ineffective drugs stay off the market, and to ensure clear, unbiased easily understandable drug information is available to prescriber, patients and consumers.

Before new drugs can be marketed in the United States, they must undergo an independent review by FDA scientists. If the review establishes that a drug is both safe and effective it is approved for marketing. In addition to prescription drugs, FDA reviews and regulates over-the-counter drugs and the generic counterparts of prescription and over-the-counter drugs and drugs designated as Orphan Drugs.

Neither FDA nor the industry can learn everything about the safety of a drug before it is approved. Continued vigilance by FDA is required after a drug is approved. This includes monitoring the quality and safety of manufacturing products, regulating the advertising and promotion of prescription drugs, ongoing surveillance for adverse events and use problems, and promoting informational and educational programs that address both medical and consumer interests.

The Office of Orphan Products Development (OOPD) Program promotes the development of products that demonstrate promise for the diagnosis and/or treatment of rare diseases or conditions. To locate such products, the OOPD interacts with the medical and research communities, professional organizations, academia, and the pharmaceutical industry, as well as rare disease groups. The OOPD administers the major provisions of the Orphan Drug Act (ODA) which provide incentives for sponsors to develop products for rare diseases. The program began in 1983 and has seen the approval of drugs for diseases such a pulmonary hypertension in the newborn, hairy cell leukemia, severe combined immunodeficiency syndrome (SCIDS), and many more rare and most often life-threatening diseases.

FY 2001 BUDGET REQUEST

ASSURING SAFETY/STRENGTHENING SCIENCE INITIATIVES

PREMARKET INITIATIVES + $2.3 MILLION, 3 FTE

Bringing Products of New Technology to Market + $2.3 million, 3 FTE

Limited scientific knowledge delays health and safety benefits and may lead to over-regulation because of inadequate understanding of the risks involved. Requested resources will be used to improve the premarket review process through:

POSTMARKET INITIATIVES + $19.5 MILLION, 119 FTE

Internet Drug Sales + $9.7 million, 75 FTE

Over the past couple of years, FDA has become aware of fraudulent activities involved with the sale of approved and unapproved prescription drugs over the Internet. The Agency is deeply concerned about maintaining the integrity of drug sales within the United States. The requested increase would allow FDA to:

Reduce the illegal promotion, sales, and distribution of approved and unapproved prescription and non-prescription pharmaceuticals via the Internet. Protect consumers from obtaining unsafe, ineffective, and fraudulent products that present a real danger to the public health. 2

Medical Errors + $6.0 million, 13 FTE

The Institute of Medicine's (IOM) 1999 report on medical errors emphasized the need for the American medical community to reevaluate practices and procedures that may lead to fewer deaths. Additional resources of $6 million in this area will be used in FY 2001 to do the following:


2 We have attempted to align the budget request and performance plan goals. All italicized items represent performance goals in the Agency's performance plan, with the specific reference following. More information on these goals and past performance can be found in the performance plan. Inspectional Activities + $3.8 million, 31 FTE

FDA will increase the inspectional coverage rate of both domestic and foreign establishments while the overall inventory continues to expand. The request for $3.8 million for inspectional activities will be used to:  

USER FEES

PREMARKET

Current Law User Fees +$2.2 million

Prescription Drug User Fee Act II (PDUFA II) + $ 2.25 million

FDA proposes to revise the distribution of projected spending of PDUFA fees for FY 2001 among the Human Drugs, Biologics, and Other Activities programs to reflect recent patterns of actual spending within the PDUFA program. This is similar to reallocations approved by the Appropriations Committees in both FY 1998 and FY 1999, and will not increase FDA's total spending for Other Activities. The net change for this reallocation is zero.

The reallocation within PDUFA is necessary to assure that PDUFA fee revenues are used to pay their fair share of the costs of FDA management (Other Activities). To make this change permanent, our FY 2001 budget request reflects our proposal to fully utilize these funds for Other Activities and possibly avoid a reprogramming later in the year. This $5 million of Salaries and Expenses funds will be made available to FDA operating programs (excluding Tobacco), as a partial alleviation of the cost impact of the recent 4.8 percent general pay raise.

The total PDUFA budget request for the Agency in FY 2001 is $149.27 million and 920 FTE, including $99.3 million and 620 FTE for the Human Drugs program. As a result of the proposal to reallocate PDUFA funds, the program will experience a decrease of $3.5 million, the difference between the $5.7 million reallocation from the Human Drugs program and a $2.245 million increase in inflationary costs. The user fees have enabled FDA to improve its performance for drug review and approval times. In FY 1991, the median approval time for human drug applications was 21 months. For all open cohorts during FY 1999, the Human Drugs program took 185 actions on New Drug Applications (NDA), 77 of which were approvals and the median approval time was 11.9 months. The fees collected in FY 2001 will enable the FDA to continue to meet its PDUFA II performance goals, which include the following:

SPECIAL PROGRAM INITIATIVES

Countering Bioterrorism + $1.2 million, 3 FTE

FDA plays a critical role in the preparation for bioterrorist attacks by reviewing new drugs and drugs used in combination with other types of products to counter the effects of anthrax and other potential bioterrorism events. The Agency must also conduct Good Manufacturing Practice inspections of drug manufacturers whose products may be stockpiled as a part of the government's bioterrorist efforts. As part of the interagency effort FDA intends to:

JUSTIFICATION OF BASE

The Human Drugs Program focuses on several primary initiatives that include meeting the mandates of the Food and Drug Modernization Act, the goals of the Prescription Drugs User Fee Act, continuing the Orphan Drug Program, and initiatives such as pediatric labeling that have a major impact on the public health. A brief description of base activities include:

FOOD AND DRUG MODERNIZATION ACT OF 1997 (FDAMA):

PREMARKET REVIEW

Prescription Drug User Fee Act of 1992 (PDUFA). Exceeded the progressively more stringent PDUFA performance goals for each successive fiscal year under PDUFA, despite unexpected, continued growth in the number of applications for original new drug applications (NDAs), resubmissions of original NDAs, efficacy supplements and manufacturing supplements to already approved marketing applications. PDUFA is a proven success for the industry, FDA, and consumers.

New Drug Evaluations. Took 185 actions on New Drug Applications (NDAs), 77 of which were approvals. The median approval time was 11.9 months, a one percent decrease in median approval time compared with FY 1998. Forty-nine of these NDAs were approved in 12 months or less. Of these 77 approvals, 27 were for new molecular entities (NMEs) - drugs that are chemically different in structure from those already on the market. The median approval time for NMEs was 9.0 months, a 25 percent decrease compared with FY 1998. Of the 27 NMEs, 19 were drugs given a priority review (products offering a significant improvement over currently marketed drugs).

6.0 months

treatment of metastatic carcinoma of the ovary that is refractory to some chemotherapy regimens.

Approved 37 priority applications (19 NMEs, nine NDAs that were not NMEs, and 9 efficacy supplements).

Pharmacology/Toxicology. Improved guidance to conduct and evaluate modern toxicological programs that support rapidly progressing clinical trials and drug reviews. To speed the drug development process, FDA reviewed 56 carcinogenicity protocols for studies prior to their initiation. FDA is involved in a number of collaborative efforts with academia, industry and the international community to evaluate the development and incorporation of new toxicological methods, both nationally and internationally.

Extended into two clinical pharmacology cooperative agreements with the University of Illinois at Urbana Champaign ($369,100) and with Meharry Medical College ($130,900).

Cancer. Successful implementation of the four initiatives from, "Reinventing the Regulation of Cancer Drugs" (released in 1996). The first initiative shortened approval times for cancer therapies by expanding the use of the accelerated approval mechanism. FDA approved three therapies under this mechanism in FY 1999. The second initiative expanded access of investigational agents to ensure that cancer patients in the US have access to potentially beneficial treatments approved by recognized foreign regulatory authorities, but are not yet marketed in the US. FDA found that few drug products approved outside of the US are considered similar or superior to those approved in the US. The third initiative included cancer patients in the review process. All FDA cancer therapy advisory committee meetings of the Oncologic Drugs Advisory Committee (ODAC) include an ad hoc member who has personal experience with the illness for which a product is being considered. The fourth initiative clarified regulations for exempting a marketed drug product from the requirements for an Investigational New Drug application (IND) when the drug is undergoing clinical testing in an unlabeled indication.

Over-the-Counter (OTC) Drug Products. Approved five new drug products and/or new indications for OTC marketing - Lamisil Cream (topical antifungal), Tagamet HB suspension (heartburn), and Pepsid AC Gelcap (heartburn), Zantac 75 Efferdose Tablet for the prevention of heartburn, and Children's Motrin Suspension for use in children six months to two years of age.

Fourteen monograph-rule making documents were published in the Federal Register, including the final rule for: alcohol warnings on anti-pyretic/analgesic products; professional labeling for aspirin, buffered aspirin, and aspirin in combination with antacid drug products; and the final rule for OTC stimulant laxative products to establish that the ingredients danthron and phenolphthalein are not generally recognized as safe and effective.

Pregnancy Labeling. Improved the current system of labeling products to make it more comprehensive and clinically meaningful by integrating input from multiple government agencies, consumer groups, medical experts, and the pharmaceutical industry.

Antibiotic Resistance. Addressed the growing problem of antibiotic resistance and its effects on drug development and regulation. Interacted with CDC on resistance activities, and NIH on developing a research plan to address the emergence of glycopeptide resistance in Staphylococcus aureus. Developed approaches to provide education on the problem of antibiotic resistance and to provide information on the appropriate use of antibiotics to health care professionals and to consumers. Developed statements to be added to antibacterial labels on antimicrobial resistance and the use of these products.

Bioterrorism. Developed regulatory policy options for stockpiling and using drug products that may be needed to respond effectively in the event of the deployment of biological weapons. Developed options for the resolution of issues; provided information on the regulatory status of various antibiotics for use against likely biological weapons; evaluated and recommended options for making unapproved products available; and provided recommendations for responding to a Department of Defense inquiry on stockpiling drug products. FDA is pursuing a collaborative relationship with the Centers for Disease Control to mutually facilitate the use of the IND mechanism for the distribution of unapproved products. This includes marketed products that are recognized by experts as the agent of choice for treatment or prophylaxis of infection following exposure to causative organisms for which the products are not approved.

Generic Drug Review. With the additional $1.0 million added to this program, approved 198 abbreviated new drug applications (ANDAs), 40 of which represent the first time a generic drug was available for the brand name product. Examples of first time approvals include: (1) Ranitidine tablets (over the counter), an H2 receptor histamine antagonist used in the treatment of ulcers (generic for Zantac 75 by Glaxo Wellcome), (2) Nicotine gum, an over-the-counter smoking deterrent (generic for Nicorette by SmithKline Beecham), (3) Cyclosporine oral solution, an agent used in prophylaxis of organ transplant rejection (generic for Neoral by Sandoz), and (4) Terazosin capsules, used for hypertension and benign prostatic hyperplasia (generic for Hytrin by Abbott Laboratories).

Issued tentative approval to 68 ANDAs. A tentative approval is issued to ANDAs awaiting expiration of patent(s) on a brand name drug. Examples of these tentative approvals include (1) Lovastatin tablets, a cholesterol lowering agent (generic for Mevacor by Merck & Co., Inc.), (2) Midazolam injection, an anesthetic agent (generic for Versed by Roche and (3) Fluoxetine capsules, an anti-depressant (generic for Prozac by Eli Lilly).

Decreased the number of review cycles from 2.7 to 2.4 cycles needed to approve abbreviated applications, as a result of FDA's initiative to contact applicants that undergo two or more major deficiency cycles.

SURVEILLANCE

Adverse Event Reporting System (AERS). Received approximately 261,000 individual safety reports (ISR) into AERS. FDA evaluates this spontaneous reporting data from AERS to identify any serious, rare, or unexpected adverse events or an increased incidence of events.

Establishment Inspections. Conducted 773 domestic establishment evaluations for Good Manufacturing Practices compliance in support of New Drug Applications. An additional 1,775 domestic establishment evaluations were conducted in support of ANDAs. Over 200 foreign establishment inspection reports (EIRs) were reviewed. The majority were in support of NDAs or ANDAs and covered the production processes including testing of an active pharmaceutical ingredient.

Recall and Drug Shortages. Recalled over 400 drugs, 16 of which were classified as Class I. (A Class I recall is a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death). Managed 10 drug shortage situations to assure the availability of medically necessary drug products to treat serious life threatening diseases, e.g., myasthenia gravis, tuberculosis, AIDS and cancer.

RESEARCH

The Product Quality Research Initiative (PQRI). Began PQRI to conduct collaborative research with scientists from academia, industry, and FDA in the areas of pharmaceutical chemistry, biopharmaceutics, and science management to identify better test methods for assessing quality of products, identify optimal manufacturing and management processes. This collaboration will enable consistent and reasonable requirements for all product quality information submitted in a regulatory filing and will streamline the drug development and approval processes for industry and FDA.

OUTREACH  

Improved communication with consumers and patients through seminars on new drug therapies and labeling; brochures for consumer and patient use; information available via the Internet; programs to make promising investigational drugs, and therapies available to patients with serious and life-threatening diseases; assuring that patient representatives are included on advisory committees considering products for HIV/AIDS, cancer and other serious diseases; and disseminating information about new and existing products.

Developed easy to read, user-friendly information for consumer in partnership with the American Pharmaceutical Association, the National Consumers League, and the National Council on Patient Information and Education. Provided consumer focused information on new and innovative drugs approvals via a new drug page at www.fda.gov/cder/consumer info/default.htm. Implemented public information campaigns, including the dangers of GHB and GBL, Y2k and Medicines, and Over-the Counter Labeling.

Expanded the pharmacist education outreach program to help pharmacists better explain the drug approval process to consumers. Updated the publication: From Test Tube to Patient: New Drug Development in the US (www.fda.gov/fdac/special/newdrug/ndd_toc.html) which describes the drug development process in lay terms for the public.

Electronic Submissions. Expanded Electronic Document Room was expanded to manage the receipt and handling of full electronic NDAs. Conducted workshops to assist industry in preparing their electronic submissions, and classes were held for FDA reviewers to train them on how to use the electronic documents. FDA received 36 NDAs that included some electronic components and nine full electronic NDAs.

Expanded the electronic document management system (EDMS). Approximately 47,000 review documents have been filed using the system which gives reviewers the capability to electronically capture, sign, and archive their regulatory review products. The Agency also completed a requirements analysis and product evaluation and conducted a pilot for a new electronic document query capability that will allow reviewers to access any electronic document directly from the desktop. These activities should help reduce review times.

Enforcement Initiatives: Enforcement Actions - Reviewed legal or administrative enforcement actions initiated by the Agency to protect consumers by removing violative products from commerce or to obtain compliance with the law. These included:

Recall and seizures. Monitored 3,756 product recalls and seizure of 25 products. As a result, numerous violative, potentially harmful products never reached consumers.

New Import Alerts in 1999 covered food, drugs (animal and human), biologic, medical device, radiation emitting devices, and cosmetic products. Examples include: bacterial contamination in mouth rinse (IA 53-20); neo-natal kidney cells (IA 57-13); allergy patches (IA 57-15); and non-sterile plastic bandages (IA 79-01).

Import Automation: Enhanced the Operational and Administrative System for Import Support, (OASIS) to allow screening of electronic import entries for attributes previously not possible using the U.S. Customs ACS system.
