What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether giving a drug called Grafalon to kidney transplant recipients with early signs of rejection can prevent long-term kidney damage. About 80 low-risk patients will receive either Grafalon plus standard care or standard care alone. Researchers will measure kidney scarring and function after two years to see if the extra treatment helps preserve the transplanted organ.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Grafalon (anti-thymocyte globulin) given as a single-day infusion to treat early borderline lesions in kidney transplant recipients
What this could lead to
If effective, this approach could slow kidney scarring and preserve graft function, potentially extending the life of the transplanted kidney.
What could go wrong
This is a small, early-stage trial, and the treatment may not slow scarring or improve function. Grafalon can cause side effects like infusion reactions and increased infection risk.

Inclusion Criteria: * Patients of either sex, older than 18 years, with no immunological risk (PRA\<20% and absence of DSA), who receive their first deceased donor or living donor KT. * Presence of BL, excluding isolated inflammation (t0, i\>0) and isolated tubulitis (t\>0, i0). * Patients receiving tacrolimus in combination with mycophenolic acid (MPA) and steroids. * Absence of clinical or subclinical and histological immunological dysfunction before randomization. * Absence of de novo DSA anti-HLA antibodies at the time of randomization. * Provision of written informed consent. * Acceptance of efficient contraception in women. Exclusion Criteria: * Recipients of a multi-organ transplant. * Re-transplants. * Patients without inflammation in the third month protocol biopsy (i0,t0), or with isolated inflammation without tubulitis (t0,i\>0) or isolated tubulitis without inflammation (t\>0,i0). * Presence of DSA antibodies before transplantation or at randomization. * Cold ischemia time \>30 hours. * Serum creatinine \>2.5 mg/dl or proteinuria \>1 g/day at randomization. * Presence of significant thrombopenia (\<100,000/mm3) or leukopenia (\<3000 mm/3) at randomization. * Previous episode of clinical or subclinical rejection (≥IA) before randomization. * CMV disease in the first three months after transplantation. * BK-polyomavirus nephropathy at randomization. * Recurrent or de novo glomerulonephritis. * Treatment with immunosuppressive drugs other than those in this clinical trial. * Patients who are positive for the human immunodeficiency virus (HIV) or with severe systemic infection, who, in the opinion of the investigator, require continued therapy. * Previous (within the last 5 years) or present malignancy, except excised basal or squamous cell carcinoma.
