The global market for drugs that treat rare diseases is growing. Orphan drug products often sit at a complicated intersection of medical science and regulatory law. From orphan drug designation and authorisation, through to the legal protections that follow, our life sciences team has the specialist knowledge to advise on all legal aspects of the orphan drug product lifecycle.

Clear, commercial advice on orphan drug law

Orphan drugs are medicines developed for rare diseases: conditions that affect only small numbers of patients individually, but which collectively represent a significant area of unmet medical need. The cost of research and development into treatments for small patient populations may be hard to justify commercially, but the UK and the European Union offer incentives to encourage investment in this area, including an entitlement to a period of market exclusivity (orphan market exclusivity) once the product is authorised. During this time, other companies may not launch an equivalent or similar product for the orphan medical condition.

In practice, the precise scope of orphan market exclusivity is often unclear; in particular, regarding whether a new product is genuinely ‘similar’ to one that is already benefiting from orphan exclusivity, or whether an exception applies because the new product offers a meaningful clinical improvement. These questions sit on the boundary of regulatory requirements and clinical evidence and the conclusions can have significant commercial consequences.

Since Brexit, the UK and EU orphan regulatory regimes are gradually diverging, with further major changes expected soon. A product’s orphan status may now differ depending on which medicines regulator is involved. Companies operating across both markets need practical advice that reflects the current and evolving legal landscape.

The combination of expertise, lateral thinking and client-centric approach sets them apart from other firms.

Cipla, global pharmaceuticals company

Our life sciences lawyers have a range of expertise and experience that makes them particularly well suited to advising in this area. We have a high level of medical and scientific literacy, based on our prior experiences in clinical and research environments, as well as deep practical knowledge of, and familiarity with how the exclusivities actually work in the UK and EU. In addition, our experts possess an understanding and a practical, commercial appreciation of how businesses plan around exclusivity over the life of a product.

Members of our life sciences litigation team can provide advice on any related disputes, including enforcement of, and challenges to, both regulatory exclusivities and patent rights. This means that we can help clients see clearly where they stand, whether that is protecting a hard-won orphan market exclusivity, or working out if there is genuine room in the market for a competing product.
