ConfIdeS Trial Summary

This trial is testing whether a new treatment can help kidney transplant patients with high levels of antibodies to get a kidney from a deceased donor.

Who is the study for?
This trial is for adults aged 18-70 with chronic kidney disease stage 5, highly sensitized (cPRA ≥99.9%), and on the waitlist for a deceased donor kidney transplant. They must be able to follow the study plan and join a 4-year extension trial. Pregnant or breastfeeding individuals, those with certain infections like HIV/HBV/HCV, active tuberculosis, or severe conditions that prevent transplantation are excluded.Check my eligibility
What is being tested?
The study tests if imlifidase used before a kidney transplant can improve renal function in patients who have high antibody levels against potential donors. It's compared to standard care including anti-CD20 antibodies and other treatments like PLEX and IVIg in an open-label, randomized Phase 3 trial over one year.See study design
What are the potential side effects?
Possible side effects include reactions related to immune system suppression such as increased risk of infections, infusion-related reactions from medications given through veins, allergic responses to drugs used during desensitization processes like Imlifidase or Eculizumab.

ConfIdeS Trial Design

2Treatment groups
Experimental Treatment
Group I: ImlifidaseExperimental Treatment1 Intervention
Imlifidase, is provided as a freeze-dried powder for concentrate for solution for infusion, 11 mg per vial. After reconstitution with sterile water for injection, the concentrate contains 10 mg/mL imlifidase. Imlifidase is administered intravenously as one infusion of 0.25 mg/kg over 15 minutes generally 24 hours prior to transplantation. A second dose of 0.25 mg/kg may be given if the first imlifidase dose is considered not to have had sufficient effect.
Group II: Best available treatmentExperimental Treatment5 Interventions
Institution-specific desensitization protocol (i.e. any combination of plasma exchange (PLEX), intravenous IVIg, anti-CD20 antibody, and eculizumab) where appropriate OR remain on wait list for a more compatible organ offer

Would I be eligible to help with this research?

"The prerequisites for enrolment in this clinical trial are that patients must have kidney disease and be between 18-70 years old. So far, 64 individuals have been admitted to the study."

Answered by AI

What other research studies have there been on Imlifidase?

"Imlifidase was first researched in 1993 at National Institutes of Health Clinical Centre. Since then, there have been 1015 completed trials with 469 currently active ones. The majority of these ongoing trials are based in San Antonio, Texas."

Answered by AI

Answered by AI

What is the main disease that Imlifidase has been shown to help with?

"Imlifidase is most commonly used to make a deceased donor's organs compatible with a positive crossmatch patient. It can also treat other conditions such as b-cell lymphomas, polyangium, neuromyelitis optica."

Answered by AI

What is the maximum amount of participants that can be in this study?

"To move forward, this study requires the recruitment of 64 individuals that meet a set of specific inclusion criteria.
