What is Orphan Drug Designation (ODD)?

Orphan Drug Designation (ODD) is a regulatory designation that applies to those types of medicine which have been specifically designed to treat a rare disease commonly referred to as an orphan disease. These diseases affect a small fraction of the population, and because of the limited market potential, pharmaceutical companies historically had little incentive to develop treatments. Important incentives to promote innovation in this underserved field are given by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA).

Conceptualization of the Orphan Drug Designation (ODD).

Regulatory authorities (e.g., FDA, EMA) award it to drugs developed to treat rare diseases: those with few patients. These products are frequently granted accelerated approvals, conditional marketing approvals and post-marketing commitments because of limited clinical trial evidence.

As a pharmacovigilance audit perspective, ODD is not a regulatory term in itself: it is a direct matter to design, execute, and manage the safety monitoring system.  This makes it a critical audit category.

The Process to Obtain Orphan Drug Designation

A drug sponsor needs to apply to the relevant regulatory body to obtain the Orphan Drug Designation. This application must include evidence that:
  • The drug is intended to treat a rare disease or condition as defined by the population thresholds.
  • There is a scientific rationale suggesting the drug may be effective for the disease.
  • The designation is granted to enable the drug to benefit the above when it is in its development and review stage.

Why the Orphan Drug Designation is Essential to the Treatment of Rare Diseases.

Hundreds of orphan drugs have been developed and approved as a result of the program, which has transformed the lives of millions of people around the world. It stimulates pharmaceutical firms to pursue projects that they would not have undertaken because of high costs and small size. ODD is a source of hope and a way to new treatments that can significantly increase quality of life and survival of patients and their families living with rare diseases.

It plays a vital role in the future of treating rare diseases with the aim to encourage the innovation process and eliminate obstacles to the development process.
