Orphan drug

From WikiMD's Wellnesspedia

An Orphan Drug refers to a pharmaceutical agent developed specifically to treat, diagnose, or prevent diseases that are so rare they are often overlooked by the mainstream pharmaceutical industry. The United States Food and Drug Administration (FDA) grants Orphan Drug designation to encourage development of treatments for diseases affecting fewer than 200,000 individuals in the country.

History

The concept of orphan drugs arose in the 1980s, with the United States Congress passing the Orphan Drug Act (ODA) in 1983. This legislation was created to address the need for drugs for rare diseases, which were not being adequately developed by the pharmaceutical industry due to the limited potential for profitability.

Orphan Drug Designation

The FDA's Orphan Drug Designation program provides various incentives for drug developers, including tax credits for clinical trial costs, assistance in the drug development process, and exclusive marketing rights upon approval.

Global Impact

Following the success of the ODA in the United States, similar regulatory frameworks have been established worldwide, including in Europe under the European Medicines Agency (EMA) and in Japan through the Ministry of Health, Labour, and Welfare.

Challenges and Controversies

While the Orphan Drug Act has significantly boosted the development of treatments for rare diseases, it has also faced criticism. Concerns include high prices of orphan drugs and companies exploiting the system for financial gain.

Orphan disease

An orphan disease is a rare disease or condition that affects fewer than 200,000 people in the United States.

Importance

Orphan diseases are often serious or life threatening.

US law

In 1983, the U.S. government passed a law, called the Orphan Drug Act, to give drug companies certain financial benefits for developing orphan drugs that are safe and effective.
