Orphan products: drugs and devices for rare diseases.

The issues of orphan products include an inadequate definition of orphan status that hampers implementation of the legislation, difficulties in evaluating the products themselves in order to ensure safety and effectiveness, neglect in developing orphan devices, and conflict over creating unnecessary monopolies and excessive profits. However, it has been demonstrated that the ODA is effective in stimulating the development of these much needed drugs and devices. The next efforts therefore can be directed toward increasing the effectiveness and ensuring the equity of the program.

Orphan drug product regulation--United States.

The legislative history of the United States Orphan Drug Act began with rare, unanimous approval by the United States Congress. The Act, mid consequently the Regulations, have evolved since then. The two-stage process of Orphan Drug designation and approval is outlined, as well as the incentives that are offered to commercial companies for their implementation. Orphan Drugs are likely to be over-represented among drugs used under "Treatment" INDs. For patent- and "drug-difference" reasons, the benefits under the Orphan Drug Act are especially valuable to those who develop biologics. By any measure, this legislation, which requires only voluntary participation, has been a success; because the human genome is likely to lead to more biologicals than orthodox drugs, this success is likely to continue into the future. But even so, the 18-year experience with Orphan Drugs in the United States has led to some 225 Orphan Product approvals that benefit many millions of patients.

Evaluation of orphan products by the U.S. Food and Drug Administration.

Orphan drug products generally are used in treating or preventing rare diseases. The small number of patients available for study may create special problems in the evaluation of these products. This paper examines some of the special problems that are associated with the design and implementation of studies to evaluate the safety and efficacy of orphan drugs. The U.S. Food and Drug Administration (FDA) has not established special criteria for evaluating orphan drugs per se, but the FDA has been flexible in evaluating drug products that present special problems, especially when these products are for treatment of serious of life-threatening illnesses. The FDA and other U.S. governmental agencies also have taken steps to promote the development and availability of drugs for rare diseases, including making these products available to patients who are in need, even before the drugs have full FDA marketing approval.

Orphan drugs: the question of products liability.

Orphan drugs, essential for the treatment of persons with rare diseases, generally are unprofitable for manufacturers to develop and market. While congressional and administrative efforts to promote the development of orphan drugs have met with modest success, application of products liability doctrine to orphan drug sponsors could subvert those efforts. This Note describes the provisions of the Orphan Drug Act and analyzes products liability law with respect to orphan drug litigation. It argues that the goals of tort law support the imposition of liability for design defect, failure to warn and negligence in testing. Finally, the Note acknowledges that liability costs create disincentives for orphan drug development and suggests mechanisms for reducing manufacturers' liability concerns.

Information service on treatment for rare diseases: the National Information Center for Orphan Drugs and Rare Diseases.

The amount of information available on rare diseases and the drug products used to treat them increases every year. The Orphan Drug Act, enacted in 1983, not only stimulated the development of orphan-drug products but also empowered the Food and Drug Administration to assist in the dissemination of information on these products to all health-care professionals. As the health-care professionals legally responsible for the dispensing of all drugs, pharmacists especially must be as informed as possible about any medication dispensed by them to their patients. The growing list of orphan-drug products makes this an almost impossible task. To assist in accessing this information, a new resource has been created.

Lucinactant (Discovery Laboratories).

Discovery Laboratories Inc (formerly Acute Therapeutics Inc (ATI) is developing lucinactant, originally identified at the Scripps Research Institute and sublicensed from Johnson & Johnson, for the potential treatment of respiratory diseases [174059], [357077], [361765], [422819]. The company anticipated filing an NDA for lucinactant in 2002, and by March 2002, lucinactant was in two pivotal phase III international trials for respiratory distress syndrome (RDS) in premature infants, a phase III trial for meconium aspiration syndrome (MAS) in full-term infants, and a phase II trial for acute lung injury/acute respiratory distress syndrome (ALI/ARDS) in adults. The company expected to complete trials by late 2003 [400846], [445166]. In February 2002, lucinactant was awarded Orphan Drug product designation in Europe for the treatment of ALI, which incorporates ARDS [440083]. By April 2001, Orphan Drug status in the US had been granted for lucinactant for MAS [301112], RDS and ARDS [404160]. The FDA also designated the drug a Fast Track product for the treatment of MAS [302120] and ARDS [301562], [302176], [404160].

An overview of the FDA publication Approved Drug Products with Therapeutic Equivalence Evaluations.

The history, purpose, and content of FDA's Approved Drug Products with Therapeutic Equivalence Evaluations (the "Orange Book") are described. When cost guidelines established in the 1970s for Medicare reimbursement prompted most states to permit generic drug product selection, an official list of interchangeable drug products was needed. Regulations for determining bioavailability and bioequivalence were published in 1977, and FDA first published Approved Drug Products in 1980. The Orange Book includes products that have been fully reviewed by FDA for both safety and effectiveness and for which new drug applications (NDAs) or abbreviated new drug applications (ANDAs) and special applications (From 5s or 6s) for antibiotics have been approved. Pursuant to the 1984 Drug Price Competition and Patent Term Restoration Act, FDA added approved nonprescription products to the Orange Book along with information about patents and periods of marketing exclusivity. Orphan drug products and certain testing and application procedures are also provided. Equivalence evaluations are provided in the Orange Book only for multisource prescription drug products that contain the same active ingredients and can be expected to have the same clinical effect when administered to patients under the conditions specified in the labeling. A coding system is used to indicate the products' equivalence evaluations according to FDA criteria, and indexes by product name and manufacturer are included. Monthly Cumulative Supplements are issued. The Orange Book contains public information and advice, but it is not an official national compendium; FDA has no position on state regulation of drug product selection by pharmacists. The equivalence evaluations do not relieve practitioners from exercising care in prescribing and dispensing products according to patients' individual needs.

Developing treatments for inborn errors: incentives available to the clinician.

Disorders resulting from inborn errors of metabolism (IEM) affect very small numbers of individuals. The entire population, however, of patients suffering the results of inherited metabolic disorders is large, and has been of increasing concern to patient groups and health care professionals in the United States as well as other countries throughout the world. The 1983 US Orphan Drug Act (ODA) serves to facilitate the development of drugs to treat rare diseases by providing several economic incentives. The sponsor of a product designated as an orphan by the Food & Drugs Administration (FDA) Office of Orphan Products Development (OPD) qualifies for tax credits on clinical trial expenses, the award of grant funding by FDA, through the OPD, and 7 years of marketing exclusivity for a designated drug, or biological product that receives FDA market approval. Orphan drug legislation in the US has benefited victims of IEM by encouraging development of drugs for metabolic deficiencies affecting populations that otherwise would be ignored. America's solution to the orphan drug problem has had worldwide impact. The success of this legislation was a factor leading to the 1993 orphan drug law in Japan; the 1997 implementation of a process whereby most FDA-approved orphan drugs and biological products will be similarly approved in Australia; and, in 1999, regulation on orphan medicinal products in the European Union (EU). Today, international support for rare disease research is providing stimulus and motivation to overcome the financial barriers and encourage development of treatment for very rare diseases throughout the world.

A proposal to improve the supply of orphan drugs.

Industrial medicinal products are not always available for the treatment of some specific patients or diseases. Appropriate research on orphan drugs, neglected doses or administration routes and patients' sensitivity to excipients, as an example, might lead to interesting results in this respect. In the United States, a specific legislation on orphan drugs dates back to 1983; in the European Union, regulations are currently being studied. The industrial production of orphan drugs might be improved following the adoption of adequate incentives. New regulations should also take care of neglected doses, and stimulate the preparation of galenic products, as an example by including a number of monographs on orphan drugs in Pharmacopoeias and National Formularies. As a matter of fact, magistral and officinal preparations made in community and hospital pharmacies in accordance with a medical prescription or with the prescription of a Pharmacopoeia or an Official Formulary, can represent an effective alternative. In this paper, the regulations enforced in the USA and Japan, the European situation, possible incentives to the industry and the role of galenic products will be discussed.
