EU/3/21/2458 - orphan designation for treatment of biliary tract cancer
zanidatamab
Orphan
Human
Overview
This medicine was designated as an orphan medicine for the treatment of biliary tract cancer in the European Union on 19 July 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:
The human epidermal growth factor receptor 2, or HER2, is a protein found at very high levels on the surface of some types of cancer cells. HER2 sends signals to the cell that can promote the growth and/or spread of cancer. Zanidatamab is a bispecific (dual-targeting) monoclonal antibody that can recognize and simultaneously bind two separate sites on HER2. This results in increased binding, removal of HER2 from the cell surface, and blocking of HER2-mediated tumour cell growth. By attaching to HER2, zanidatamab activates cells of the immune system to kill the cancer cells. These effects lead to the death of cancer cells.
Based on description provided by sponsor
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 biliary tract cancer 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 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.
