ClinConnect Summary

The Pediatric Lupus Nephritis Mycophenolate Mofetil (PLUMM) Study is a clinical trial looking at how well a medication called Mycophenolate Mofetil (MMF) works for children and young adults aged 8 to 21 who have a condition known as lupus nephritis, which affects the kidneys. This study will last for one year and is designed to compare two different ways of giving MMF: one based on the patient's body size and the other tailored to individual needs based on specific measurements in the blood. The goal is to see which method is safer and more effective for treating this kidney condition.

To be eligible for the study, participants must be newly diagnosed with a specific type of lupus nephritis and able to take MMF as prescribed by their doctor. They should also be willing to follow the study’s requirements, which include regular visits and completing questionnaires in English or Spanish. Throughout the trial, participants can expect to receive careful monitoring and support while helping researchers learn more about treating this serious condition. If you or someone you know might be interested in joining the study, it’s important to discuss it with a healthcare provider to see if it’s a good fit.

• • 14. Herbal supplements with pharmaceutical properties must be discontinued at least 1week prior to Baseline visit, unless there are sufficient data available regarding the duration of an herbal medication's pharmacokinetic and pharmacodynamic effects to allow a shorter or longer washout to be specified (e.g., 5 half-lives).
