Is Rituximab Effective? New Insights into EGPA Treatment

Imagine your immune system suddenly decides your own blood vessels are the enemy. It floods them with white blood cells, causing inflammation that can damage lungs and nerves. This condition is rare, but for patients, finding the right EGPA treatment is a daily priority. Doctors often rely on strong drugs to calm this internal storm, yet knowing which drug works best remains a challenge.

A recent systematic review analysed clinical trials published between 2018 and 2023. The researchers wanted to know if two specific biologics—rituximab and benralizumab—perform better than existing options.

Comparing options for EGPA treatment

First, the team looked at rituximab. If you administer this drug, it targets specific immune cells to stop the attack. The study measured remission rates after 180 days. The results showed that 63.5% of patients on rituximab achieved remission, compared to 60.4% on conventional therapy. This is a negligible difference. The data suggests that rituximab provides no clear benefit over standard care based on current evidence.

Next, the researchers examined benralizumab. In this case, the drug was compared directly against mepolizumab, another established medication. The measurements showed nearly identical results. Remission rates hovered around 58% for both groups. Relapse rates were also consistent at 30%.

If a patient switches between these two drugs, the study implies they might expect a similar outcome. However, the certainty of this evidence is low. While the study measured specific recovery rates, the small number of trials means the picture is still slightly out of focus. We have options, but we do not yet have a magic bullet.
