Orphan designation

Please note that this product was withdrawn from the Community register of designated orphan medicinal products in February 2013 on request of the sponsor.

On 26 November 2010, orphan designation (EU/3/10/809) was granted by the European Commission to Abraxis BioScience Limited, United Kingdom, for nanoparticle albumin-bound paclitaxel for the treatment of pancreatic cancer.

The sponsorship was transferred to Celgene Europe Limited, United Kingdom, in August 2011.

What is pancreatic cancer?

Pancreatic cancer is cancer of the pancreas, a small organ that lies behind the stomach. The pancreas has two functions: to produce a juice that helps with the digestion of food, and to produce hormones such as insulin. Due to the absence of symptoms in the early stages of pancreatic cancer, the majority of patients are diagnosed when the cancer has spread locally or to other parts of the body.

Pancreatic cancer is a very severe and life-threatening disease that is associated with shortened life expectancy.

What is the estimated number of patients affected by pancreatic cancer?

At the time of designation, pancreatic cancer affected approximately 1.3 in 10,000 people in the European Union (EU). This was equivalent to a total of around 66,000 people*, and is below the threshold for orphan designation, which is 5 people in 10,000. This is based 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 27), Norway, Iceland and Liechtenstein. At the time of designation, this represented a population of 506,300,000 (Eurostat 2010).

What treatments are available?

At the time of designation, several medicines were authorised for treating pancreatic cancer in the EU. The choice of treatment depended on several factors, including how advanced the disease is. Treatments included surgery, radiotherapy (treatment with radiation) and chemotherapy (medicines to treat cancer).

Nanoparticle albumin-bound paclitaxel is already authorised in the EU for the treatment of breast cancer under the name ‘Abraxane’. The sponsor has provided sufficient information to show that the medicine might be of significant benefit for patients with pancreatic cancer, as early studies show improved outcomes in patients when it is used in combination with other treatments. This assumption will need to be confirmed at the time of marketing authorisation, in order to maintain the orphan status.

How is this medicine expected to work?

Paclitaxel, the active substance in nanoparticle albumin-bound paclitaxel, belongs to the group of anticancer medicines known as the ‘taxanes’. Paclitaxel blocks the ability of cancer cells to break down their internal ‘skeleton’ that allows them to divide and multiply. With their skeleton still in place, the cells cannot divide and they eventually die.

Paclitaxel has been available as an anticancer medicine since 1993 but is not authorised for pancreatic cancer. Conventional types of paclitaxel contain substances that dissolve the paclitaxel, but which can cause hypersensitivity (allergic) reactions. Nanoparticle albumin-bound paclitaxel does not contain these substances. Instead, the paclitaxel is attached to a human protein called albumin in tiny particles known as ‘nanoparticles’. This makes it easy to prepare a suspension of paclitaxel, which can be infused into a vein. The nanoparticles may also modify the way the medicine is distributed within the body, and this is expected to have a positive effect on its benefits and risks, in comparison with conventional medicines containing paclitaxel.

What is the stage of development of this medicine?

The effects of nanoparticle albumin-bound paclitaxel have been evaluated in experimental models.

At the time of submission of the application for orphan designation, clinical trials with nanoparticle albumin-bound paclitaxel in patients with pancreatic cancer were ongoing.

At the time of submission, nanoparticle albumin-bound paclitaxel was authorised under the name ‘Abraxane’ for the treatment of breast cancer in the EU and in several countries outside the EU.

At the time of submission, nanoparticle albumin-bound paclitaxel was not authorised anywhere in the EU for pancreatic cancer. Orphan designation of the medicine had been granted in the United States for this condition.

In accordance with Regulation (EC) No 141/2000 of 16 December 1999, the COMP adopted a positive opinion on 9 September 2010 recommending the granting of this designation.

Opinions on orphan medicinal product designations are based on the following three criteria
  • 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 European Union) 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.
