Decreased Immunologic Activity clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT02120482 Terminated - Clinical trials for Antibody-mediated Rejection

Combined Apheresis for ABO-incompatible Transplantation - a Pilot Study

Start date: October 2014
Phase: N/A
Study type: Interventional

Recipient desensitization is a prerequisite for successful ABO-incompatible kidney transplantation (ABOi-KTX). Published desensitization protocols commonly include the use of plasmapheresis or selective (i.e. antigen-specific) immunoadsorption (IA), together with distinct immunomodulatory measures (e.g. CD20 antibody rituximab). Selective IA represents an efficient but cost-intensive therapy. An alternative could be the use of semi-selective (non-antigen-specific) IA. Even though highly efficient in depleting ABO-specific IgG, semi-selective IA may only marginally affect levels of ABO-specific IgM, which might - due to the strong complement activating potential of this Ig class - exhibit a potential risk for (hyper)acute antibody-mediated rejection (Wahrmann et al. 2012, Nephrol Dial Transplant). In a randomized crossover trial (Eskandary et al. 2014, Nephrol Dial Transplant; www.clinicaltrials.gov, NCT01698736) we have recently shown that the combination of semi-selective IA together with membrane filtration, a technique primarily used in the field of LDL apheresis, can yield excellent elimination of both IgM and IgG reactivities, as well as essential macromolecules such as the classical complement key component C1q. In this two-center phase 2 pilot study (N=10) we plan to evaluate the safety and efficacy of this alternative desensitization strategy in ABOi-KTX.
