EU/3/21/2486: Orphan designation for the treatment of multiple myeloma

Talquetamab, also known as JNJ-64407564, is an antibody, a protein that attaches to specific targets in the body. The targets for talquetamab are CD3, a protein found on T-cells (part of the immune system, the body’s natural defences) and GPRC5D, a protein found on the surface of myeloma cells. By attaching to both a T-cell and a myeloma cell, the medicine brings them into contact, encouraging the T-cell to attack and destroy the cancerous cell. This is expected to reduce growth of the cancer and control its symptoms.

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

The effects of the medicine had been evaluated in experimental models.

Clinical trials with the medicine in patients with multiple myeloma were ongoing.

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.
