Overview

On 4 February 2002, orphan designation (EU/3/01/079) was granted by the European Commission to Discovery Laboratories, Inc., United Kingdom, for sinapultide, dipalmitoylphosphatidylcholine, palmitoyl-oleoyl phosphatidylglycerol and palmitic acid (Surfaxin) for the treatment of acute lung injury.

The sponsorship was transferred Pharm Research Associates (UK) Limited, United Kingdom, in September 2010.

The sponsorship was transferred to Pharmaceutical Research Associates Group B.V., Netherlands in May 2019.

Acute lung injury (ALI) is a pulmonary disorder characterised by lesions of lung cells and acute lung inflammation. It may occur as a result of direct injury to the lung such as toxic gas inhalation or chest trauma, or it may be associated with a wide variety of disorders affecting other organs such as blood infections, non-thoracic trauma, acute pancreatitis or cardio-vascular shock. ALI is a life-threatening condition.

At the time of designation, acute lung injury affected approximately 1.8 in 10,000 people in the European Union (EU)*. This is equivalent to a total of around 68,000 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: The number of patients affected by the condition is estimated and assessed for the purpose of the designation, for a European Community population of 377,000,000 (Eurostat 2001). This estimate is based on available information and calculations presented by the sponsor at the time of the application and may thus differ from the true number of patients affected by the condition.

There was no medicinal product specifically authorised to treat this condition in the European Union at the time of submission of the application for orphan drug designation. Beside correction of the cause of ALI when possible, available therapies are supportive, consisting in symptomatic measures (including oxygen and in severe cases mechanical ventilation).

Surfaxin is a surfactant agent. Surfactant substances are naturally produced in lungs and contribute to maintain pulmonary alveoli open and thus functional. The natural surfactant is destroyed in patients with ALI. Surfaxin is intended to compensate the loss of natural surfactant in patients with ALI and thus aims to improve the pulmonary function of these patients.

The effects of Surfaxin have been evaluated in experimental models and clinical investigations to measure the effect of Surfaxin in ALI were ongoing at the time of submission of the application for orphan designation. Patients included are adults presenting the most severe form of ALI: acute respiratory distress syndrome.

Surfaxin had not been authorised in any country at the time of submission of the application for orphan designation. In the US orphan drug status was granted in the treatment of acute respiratory distress syndrome in adults.

In accordance with Regulation (EC) No 141/2000 of 16 December 1999, the COMP adopted a positive opinion on 21 November 2001 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
