Apremilast is in development as an oral treatment for oral ulcers in people with active Behçet’s disease. Behçet’s disease (or Behçet’s syndrome) is a rare and poorly understood condition that results in inflammation of the blood vessels and tissues. The condition is characterised by flare-ups (relapses) followed by periods where the symptoms disappear (remission). The cause of Behçet’s disease is thought to be an interaction between genetics and environmental factors. As Behçet’s disease affects multiple systems it has various symptoms such as mouth or genital ulcers, painful eyes and blurred vision, acne-like spots and painful joints. The most commonly reported symptoms are oral and genital ulcers.
Apremilast works by suppressing the activity of inflammatory pathway caused by molecules such as interleukins and tumour necrosis factors. In turn this reduces inflammation. Currently, specific curative treatment options for Behçet’s disease are very limited and treatment relies on controlling symptoms and relieving pain. Apremilast has shown promise in targeting oral ulcers in patients with Behçet’s disease, and if licensed it could be an effective treatment option for this patient group.
BCX7353 is an oral treatment that works by blocking the activity the specific pathway that becomes overactive in patients with angioedema. By blocking this pathway, BCX7353 is expected to reduce the number of angioedema attacks. Early studies of BCX7353 has shown that it helped to prevent swelling and inflammation in HAE. In addition, BCX7353 has the distinct advantage over current treatment of being administered orally, making it easier to use for routine prevention of HAE attacks.
