Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: ImlifidaseExperimental Treatment1 Intervention
Subjects randomized to imlifidase treatment received one intravenous dose of imlifidase, 0.25 mg/kg, administered over 15 minutes.
Group II: Plasma ExchangeActive Control1 Intervention
Subjects randomized to plasma exchange (PE) treatment received 5-10 sessions of PE, as judged by the investigator. Immunoadsorption (IA) could replace PE, at the discretion of the investigator.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the participant recruitment rate for this research project?

"Currently, enrolment for this medical trial is closed; it was first published on April 30th 2019 and last updated November 16th 2022. However, there are currently 30 clinical trials enrolling patients with rejection; transplant kidney issues as well as 5 studies in need of participants studying Imlifidase."

Answered by AI

Is Imlifidase an acceptable risk for patients considering its therapeutic effects?

"While there is evidence of Imlifidase's safety, its efficacy still needs to be evaluated. Consequently, we have assigned it a score of 2 on our scale from 1-3."

Answered by AI

Is there capacity for additional participants in this research endeavor?

"This particular study, posted on April 30th 2019 and last updated November 16th 2022, is not currently enrolling patients. However, 35 other clinical trials are actively recruiting participants for their research studies."

Answered by AI

Have any additional experiments been conducted surrounding Imlifidase?

"At present, 5 trials exploring Imlifidase are live with 1 in Phase 3. These clinical studies have 37 locations spread across the United States, most notably New york City."

Answered by AI

What clinical conditions is Imlifidase typically administered for?

"Imlifidase has been demonstrated to be a useful intervention for desensitizing kidneys prior to transplantation."

Answered by AI

What is the current geographic scope of this research endeavor?

"This clinical trial is being hosted at the Brigham and Women Hospital in Boston, Mayo Clinic in Rochester, and Cedars-Sinai Medical Center in Los Angeles. Additionally it will be conducted out of 4 other medical sites as well."
