On 2 April 2012, orphan designation (EU/3/12/978) was granted by the European Commission to Dr Nicola J Robertson, United Kingdom, for melatonin for the treatment of perinatal asphyxia.
The sponsorship was transferred to Chiesi Farmaceutici S.p.A., Italy, in July 2016.
- What is perinatal asphyxia?
Perinatal asphyxia happens when babies are born without enough oxygen in their blood. This is generally due to interruptions of the oxygen supplied by the mother through the placenta or the umbilical cord. Perinatal asphyxia can cause damage to the brain and other organs.
Perinatal asphyxia is a long-term debilitating disease because it can lead to the child being severely handicapped, with mental retardation and physical disabilities. It is also life threatening, as up to a fifth of the babies with the condition will die within the first days after birth.
- What is the estimated number of patients affected by the condition?
At the time of designation, perinatal asphyxia affected less than 1 in 10,000 people in the European Union (EU)*. This is equivalent to a total of fewer than 51,000 people, and is below the ceiling 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. This represents a population of 506,300,000 (Eurostat 2011).
- What treatments are available?
At the time of orphan designation, there was no treatment for perinatal asphyxia authorised in the EU. Babies with perinatal asphyxia received supportive treatment, and they were sometimes cooled down to a body temperature lower than normal (hypothermia) for 12 to 72 hours after birth to reduce the extent of the damage caused by the asphyxia.
- How is this medicine expected to work?
Melatonin is a naturally occurring hormone. The exact way in which it could work in perinatal asphyxia is not fully understood, but data from experimental models show that it has a protective effect on nerve cells by increasing their survival.
- What is the stage of development of this medicine?
At the time of submission of the application for orphan designation, the evaluation of the effects of melatonin in experimental models was ongoing.
At the time of submission, no clinical trials with melatonin in patients with perinatal asphyxia had been started.
At the time of submission, melatonin was not authorised anywhere in the EU for perinatal asphyxia or designated as an orphan medicinal product elsewhere for this condition.
In accordance with Regulation (EC) No 141/2000 of 16 December 1999, the COMP adopted a positive opinion on 8 February 2012 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 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.

Review of designation
The Committee for Orphan Medicinal Products reviews the orphan designation of a product if it is approved for marketing authorisation.
