ClinConnect Summary

This clinical trial is studying a new drug called GNG-DE to see how well it works and how safe it is compared to an existing reference drug for preventing infections caused by meningococcal bacteria. The trial is for males and females aged 3 to 55 years old who are in good health, meaning they won’t have any serious illnesses or recent infections that could affect the study. Participants will need to provide consent, and for younger participants, their parents will need to sign a consent form as well.

If you join this trial, you will receive either the new drug or the reference drug through an injection. Throughout the study, you will make several visits to the clinic where the team will monitor your health and any reactions you might have to the drug. It’s important to note that there are specific criteria for joining, such as not having allergies to the drugs being tested or having certain medical conditions. The trial is currently not recruiting participants, but it aims to gather important information about the safety and effectiveness of GNG-DE when compared to the existing treatment.
