Kidney transplant breakthrough: Biopsy-Guided drug adjustments could save grafts
NCT ID NCT02444429
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a routine biopsy three months after kidney transplantation can help doctors adjust immunosuppressive drugs to prevent graft loss and reduce side effects. 346 patients were split into two groups: those with mild inflammation received extra steroids, while those without inflammation had their steroids reduced. The goal was to see if these tailored approaches improve kidney function and reduce damage.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Corticosteroid boluses (methylprednisolone) and corticosteroid withdrawal
- What this could lead to
- If successful, this could lead to better long-term kidney transplant survival and fewer side effects from immunosuppressants.
- What could go wrong
- This is a completed phase 3 trial, but results may not apply to all transplant patients. Risks include rejection or infection from changing immunosuppression.

Inclusion Criteria: 1. Common to both sub-studies (A and B) * Renal transplant patient aged between 18 and 75. * Patient who received a first or second renal graft * Immunosuppressive treatment consisting of an anti-calcineurin \[cyclosporine (trough levels: 150\<T0\<300)\], or tacrolimus (trough levels: 8\<T0\<12), mycophenolate mofetil and corticosteroids. * Patient who benefited from a screening renal biopsy 3 months after the graft * Patient who gave their informed consent * Patient affiliated to a social security scheme or being a beneficiary of such a scheme 2. Specific to sub-study A * Presence of "borderline" inflammatory infiltrates on the screening biopsy at 3 months as defined by the Banff classification 2013: * Absence of vascular lesions (v0) and: * tubulitis regardless of its significance (t1-3) with minimum interstitial infiltrate (i0-i1) OR * interstitial infiltrates (i2-3) without significant tubulitis (≤ t1) 3. Specific to sub-study B Absence of significant inflammatory infiltrates (i0-1 and t0) on the screening biopsy at 3 months Exclusion Criteria: 1. Common to both sub-studies (A and B) * Histological subclinical rejection criteria on the screening biopsy at 3 months (Banff 2009: \> i2+t2) * Donor specific antibodies in historical serum or de novo appearance during the first 3 months * Humoral lesions on the 3-month biopsy (Banff score g+ptc\>2) * "Classic" acute rejection episode proven by biopsy during the first 3 months * Multiorgan transplantation * 3rd (or subsequent) renal transplantation * BK virus-associated nephropathy on the screening biopsy * Contraindication to the 1-year screening biopsy 2. Specific to sub-study B Initial nephropathy with a high risk of recurrence on corticosteroid withdrawal: segmental and focal and segmental glomerulosclerosis, lupus nephritis, vasculitis, or membranous glomerulonephritis
