EU/3/22/2711: Orphan designation for the treatment of Menkes disease

This medicine is a synthetic copper transporter and belongs to the class of: Immunomodulators

The synthetic copper transporter is a copper nanocluster organised as an aggregate of copper atoms conjugated to acetate, histidinate and ascorbate ions.

Due to their size of less than 1 nanometer, the copper nanoclusters are able to cross physiological barriers so they can be distributed throughout the body, delivering copper to the deficient organs and restoring the copper-dependent physiological functions altered by Menkes disease.

At the time of submission of the application for orphan designation:

• The evaluation of the effects of the medicine in experimental models was ongoing.
• No clinical trials with the medicine in the patients with Menkes disease has been started.

More information on how potential new medicines are tested during their development is available on Authorisation of medicines.

Medicines intended for rare diseases can be granted an orphan designation during their development.

The orphan designation allows the developer to benefit from:

• scientific and regulatory support to advance their medicine to the stage where they can request marketing authorisation;

• market exclusivity once the medicine is on the market.

To qualify for orphan designation, a medicine must meet a number of criteria:

• it must be intended for the treatment, prevention or diagnosis of a disease that is life-threatening or chronically debilitating;

• the prevalence of the condition in the EU must not be more than 5 in 10,000 or it must be unlikely that marketing of the medicine would generate sufficient returns to justify the investment needed for its development;

• there are no satisfactory alternative methods for the diagnosis, prevention or treatment of the condition or, if such a method exists, the medicine is of significant benefit to those affected by the condition.

EMA's Committee for Orphan Medicinal Products (COMP) is responsible for issuing opinions on applications for orphan designations.

The Agency sends the COMP opinion to the European Commission, which is responsible for granting the orphan designation. The full list of orphan designations is available in the Community register of orphan medicinal products for human use.
