Whilst the toxicology studies continue to be required for regulatory submissions, there are opportunities to both reduce the number of animals and refine procedures used within the studies, by implementation of best practice study designs and processes identified by NC3Rs-industry data sharing projects. With the rapid expansion of biotherapeutics within the industry expected to continue or increase, the number of compounds within company pipelines, and hence the number of NHPs used for testing, are likewise anticipated to grow.

While most of these barriers apply also to the use of other vertebrate species, there is arguably a greater imperative to overcome them in the case of the NHPs, given their high sentience and the degree of societal concern about their use. To do so will require greater awareness among researchers of the availability and scientific benefits of 3Rs approaches; increased funding for the development of new research models and tools, infrastructure and training; more robust scientific and ethical review of research proposals involving NHPs; better retrospective evaluation of the benefits accrued from NHP research; and improved knowledge transfer.
