Is the future clear?

As Mia’s need for targeted treatment becomes clear, the evolution of therapeutic options provides hope for the future

The treatment landscape is changing due to recent and ongoing clinical trials offering evidence-based therapeutic options for childhood psoriasis, including those already licensed for use in adults. Secukinumab is one example of a biologic treatment which has recently gained approval in Europe for children following positive results in adults and proven effectiveness in Phase III trials.

As the treatment landscape continues to evolve, you can see the journey through investigation and approval processes that many of the treatments for paediatric psoriasis have taken.

Clinical trials are ongoing for more targeted biologic therapies

The IL-17R inhibitor brodalumab (NCT03240809¹) is in paediatric clinical trials for psoriasis along with the IL-23 inhibitors guselkumab (NCT03451851²) and tildrakizumab (NCT03997786³), and the TNF-a inhibitor certolizumab pegol (NCT04123795⁴).

Recent data suggests adult treatments are also effective in children

While limited data from clinical trials has been reported, results appear to be consistent, if not better than, adult data.

Professor Paller gives us her summary of the efficacy and safety in children vs adult data.

Having well-controlled psoriasis in paediatric patients will reduce the impact of psoriasis in later life

There is concern that undertreating children may facilitate the ‘psoriatic march’ from severe untreated inflammation in childhood and its associations to cardiovascular morbidity and mortality in adults⁹.

Professor Vakirlis describes why early treatment is so important.

In making treatment decisions, it is important for physicians to consider each child’s physical presentation, comorbidities and the effect on QoL, along with the patient’s family. Given that there is no ‘one size fits all’ treatment algorithm⁹, having as many treatments available to children with psoriasis will offer patients a much greater chance of successful disease control early on with the added bonus of improving long-term health.
