EU/3/16/1766 - orphan designation for treatment of diffuse large B-cell lymphoma
Venetoclax
OrphanHuman
Overview
Please note that this product was withdrawn from the Union Register of orphan medicinal products in February 2025 on request of the Sponsor.
On 14 October 2016, orphan designation (EU/3/16/1766) was granted by the European Commission to Abbvie Ltd, United Kingdom, for venetoclax for the treatment of diffuse large B-cell lymphoma.
The sponsorship was transferred to AbbVie Deutschland GmbH & Co. KG, Germany, in May 2018.
Diffuse large B-cell lymphoma is a type of blood cancer and the most common form of a group of blood cancers known as non-Hodgkin lymphomas.
Diffuse large B-cell lymphoma affects a type of white blood cell called B lymphocytes, or B cells. In patients with this cancer, the B cells multiply too quickly and live for too long, so there are too many of them in the lymph nodes. The first sign of the disease is usually a lump in the neck, under the arm or in the groin area, which is caused by an enlarged lymph node. Patients with diffuse large B-cell lymphoma may also have fever, tiredness, night sweats or weight loss that have no obvious cause.
Although some people with diffuse large B-cell lymphoma can be cured, it remains a serious and life-threatening disease, particularly when the disease is diagnosed late or has come back after treatment.
At the time of designation, diffuse large B-cell lymphoma affected approximately 4 in 10,000 people in the European Union (EU). This was equivalent to a total of around 205,000 people*, and is below the ceiling for orphan designation, which is 5 people in 10,000. This isbased on the information provided by the sponsor and the knowledge of the Committee for Orphan Medicinal Products (COMP).
* Disclaimer: For the purpose of the designation, the number of patients affected by the condition is estimated and assessed on the basis of data from the European Union (EU 28), Norway, Iceland and Liechtenstein. This represents a population of 513,700,000 (Eurostat 2016).
At the time of designation, several medicines were authorised for the treatment of diffuse large B-cell lymphoma in the EU. The main treatment was chemotherapy (medicines to treat cancer) usually in combination with medicines called monoclonal antibodies and sometimes with radiotherapy (treatment with radiation). Autologous haematopoietic (blood) stem-cell transplantation was also used in patients at risk of the disease coming back after treatment. This is a procedure where the patient's bone marrow is replaced with the patient's own stem cells to form new bone marrow that produces healthy blood cells.
The sponsor has provided sufficient information to show that venetoclax might be of significant benefit for patients with diffuse large B-cell lymphoma because data from a few patients showed that venetoclax may be effective in patients whose disease had come back after or had not responded to previous treatment. This assumption will need to be confirmed at the time of marketing authorisation, in order to maintain the orphan status.
Venetoclax is expected to work by blocking proteins called Bcl-2. These proteins allow cells to stay alive by preventing the natural process that leads to cell death (apoptosis). Bcl-2 proteins can be found in high levels in cancer cells. By blocking the action of these proteins, the medicine is expected to make cancer cells more responsive to this natural process, causing their death and slowing the growth of the cancer.
The effects of venetoclax have been evaluated in experimental models.
At the time of submission of the application for orphan designation, clinical trials with venetoclax in patients with diffuse large B-cell lymphoma were ongoing.
At the time of submission, venetoclax was not authorised anywhere in the EU for diffuse large B-cell lymphoma. Orphan designation of the medicine had been granted in the EU and the United States for chronic lymphocytic leukaemia and for acute myeloid leukaemia, and in the United States for diffuse large B-cell lymphoma.
In accordance with Regulation (EC) No 141/2000 of 16 December 1999, the COMP adopted a positive opinion on 8 September 2016 recommending the granting of this designation.
- the seriousness of the condition;
- the existence of alternative methods of diagnosis, prevention or treatment;
- either the rarity of the condition (affecting not more than 5 in 10,000 people in the EU) or insufficient returns on investment.
Designated orphan medicinal products are products that are still under investigation and are considered for orphan designation on the basis of potential activity. An orphan designation is not a marketing authorisation. As a consequence, demonstration of quality, safety and efficacy is necessary before a product can be granted a marketing authorisation.
