TAVNEOS for Wegener's Granulomatosis

This trial tests a new treatment called TAVNEOS (also known as Avacopan) for individuals with Wegener's Granulomatosis, a condition causing inflammation in blood vessels and affecting areas like the ears, nose, and throat. The trial aims to determine if TAVNEOS, when added to standard care, can manage symptoms more effectively than a placebo. Participants will receive either TAVNEOS or a placebo alongside their usual treatment and will be monitored for a year. Those diagnosed with active ear, nose, and throat symptoms from Wegener's Granulomatosis might be suitable candidates. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

The trial does not specify if you need to stop your current medications. However, you will continue with your standard treatment as determined by your doctor, and you cannot use certain medications like strong inducers of CYP450 (a group of enzymes that process drugs in the body). It's best to discuss your current medications with the trial team.

Research has shown that Avacopan, also known as TAVNEOS, is generally well-tolerated in clinical studies. In a study with 330 participants who had conditions similar to Wegener's Granulomatosis, 72% of those taking Avacopan achieved remission, meaning their symptoms improved significantly. This suggests the treatment works well for many people.

Regarding safety, Avacopan showed similar results to other treatments like prednisone, which is often used. The studies did not find any major safety issues specific to Avacopan.

Unlike the standard of care for Wegener's Granulomatosis, which typically involves corticosteroids and immune-suppressing drugs, TAVNEOS (avacopan) works by targeting the complement system, specifically the C5a receptor. This approach helps reduce inflammation without the broad suppression of the immune system seen with traditional treatments. Researchers are excited about TAVNEOS because it offers the potential for fewer side effects and a more focused mechanism of action, which could lead to better outcomes for patients.

Research has shown that TAVNEOS (avacopan), which participants in this trial may receive, yields promising results for treating granulomatosis with polyangiitis (GPA). In a study with 330 participants, 72% of those taking TAVNEOS went into remission, significantly improving their symptoms. Another study found that 55.9% of patients remained in remission for a year while using TAVNEOS. These findings suggest that TAVNEOS might effectively reduce GPA symptoms, particularly in the ears, nose, and throat areas.¹²⁴⁵⁶
