TGActhar: Treatment of Chronic Antibody-mediated Rejection in Kidney Transplant With Acthar
Study Details
Study Description
Brief Summary
This is an open label safety and feasibility trial using Acthar® in addition to the investigators center-specific standard therapy, which could include increase in maintenance immunosuppression, high dose IVIG (2 g/Kg), and/or Rituximab, in patients with CAMR.

Phase 4 |
Detailed Description
Subjects will receive Acthar® 40 units twice a week subcutaneously for 2 weeks. If the drug is well tolerated the dose will be increased to 80 units twice a week for another 22 weeks. The patients will be maintained on their center-specific standard maintenance regimen, typically consisting of Tacrolimus, mycephenolate mofetil/Sodium, and prednisone.
After screening for the inclusion/exclusion criteria, the patients will be consented and enrolled in the study. The initial visit and subsequent study-related visits at 4, 8, 12, 24, 36 and 52 weeks will include routine evaluation and physical examination and laboratory studies including CBC, electrolyte panel, eGFR, albumin, liver enzymes, and CNI/sirulimus drug level, according to the center's standard of care. DSA will be tested at week 24, and 52 and patients will undergo a biopsy at week 52, as a part of the investigators standard of care. The biopsies will be evaluated by light and electron microscopy using standard histological Banff criteria, and staining for CD68.

Outcome Measures
Primary Outcome Measures
- Efficacy end point (Composite of graft loss, death, decrease in eGFR>10%, and increase in proteinuria) [12 months]
Composite of graft loss, death, decrease in eGFR>10%, and increase in proteinuria (defined as >50% increase if baseline proteinuria <2 g, or persistence of proteinuria >2 g otherwise)
Secondary Outcome Measures
- Safety (Serious adverse events) [12 months]
Serious adverse events
- Graft loss (Kidney allograft failure or death) [12 months]
Kidney allograft failure or death
- Graft function (>10% decrease in eGFR) [12 months]
>10% decrease in eGFR
- Proteniuria (Increase in proteinuria >50% if baseline proteinuria<2 g, or persistence of proteinuria >2 g otherwise) [12 months]
Increase in proteinuria >50% if baseline proteinuria<2 g, or persistence of proteinuria >2 g otherwise
