EU/3/21/2508 - orphan designation for prevention of bronchopulmonary dysplasia

allogeneic umbilical cord mesenchymal cells-derived extracellular vesicles

Overview

This medicine was designated as an orphan medicine for the prevention of bronchopulmonary dysplasia in the European Union on 15 October 2021.

This means that the developer will receive scientific and regulatory support from EMA to advance their medicine to the stage where they can apply for a marketing authorisation.

Orphan designation does not mean the medicine is available or authorised for use. All medicines, including designated orphan medicines, must be authorised before they can be marketed and made available to patients in the EU.

During the medicine's development, doctors may be able to enrol patients in clinical trials investigating the medicine. For information on ongoing clinical trials in the EU, see:

• EU Clinical Trials Register

• ClinicalTrials.gov

How the medicine is expected to work

This medicine is made of small particles (nanoparticles) naturally released from cells, containing proteins and nucleic acids, enclosed in a double layer of lipids.

The particles have anti-inflammatory, immunomodulating and pro-regeneration effects, and are expected to reduce lung damage and inflammation, improving the structure of lung alveoli, attenuating lung fibrosis (scarring), and increasing exercise capacity. Their intratracheal administration is expected to prevent the symptoms of bronchopulmonary dysplasia in preterm newborn babies.

Stage of development at time of orphan designation

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 patients at risk of bronchopulmonary dysplasia had been started.

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

About orphan designation

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 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.
