Study summary

BEAT-BK will see the effect of immunosuppression reduction/modification with and without IVIG on BKPyV infection, allograft function, allograft loss, acute transplant rejection, immunosuppression load and death in kidney and simultaneous kidney pancreas transplant recipients with polyomavirus infections (BKPyV).

Read the detailed description

BKPyV infection is a rare but also devastating disease in kidney and SPK transplant recipients. Immunosuppression used in transplantation minimises the risk of acute rejection and eventual graft loss, but suppression of the immune system increases the risk of opportunistic infections and reactivation of latent viruses causing disease, such as BKPyV infection. Therefore, balancing the complications of excessive versus inadequate immunosuppression is a key priority for patients and health professionals. The BEAT-BK trial is designed through a structured, consensus process, and informed by the pilot observational data generated by the investigators. The conventional immunosuppression reduction approach may include judicious reduction in the doses of calcineurin inhibitors and anti-proliferative agents, or conversion to less potent immunosuppression therapy such as a switch from tacrolimus to cyclosporine, or mycophenolate to azathioprine. While adjuvant therapy is not commonly used, 63% of participants would consider IVIG as a 'rescue', when conventional therapy has failed, or the graft function is deteriorating rapidly. IVIG is a nondepleting agent containing natural antibodies with potential antiviral and immunomodulatory properties. It is used against some chronic infections (Epstein-Barr virus) and the treatment of antibody-mediated rejection in kidney transplantation. In BKPyV infection, the certainty of the evidence for IVIG is very low due to imprecision, and high risk of bias (small, case series, retrospective cohorts), but it holds promise based on findings from our observational data (n = 50). Recipients with BKPyV-DNAemia who received IVIG as adjuvant therapy were more likely to achieve complete viral clearance at 12 months (77.3% vs. 33.3%, p \< 0.01) and less likely to relapse (11% vs. 27.3%, p=0.01) compared to recipients who received conventional therapy alone.

No

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Aged 2 years or above
  2. Have received a kidney or simultaneous pancreas-kidney transplant
  3. Have BKPyV-Viremia (detected by RT-PCR) with a viral count ≥ 5,000 copies per mL, or histological confirmation of BKPyVAN, within 3 weeks prior to randomisation.
  4. Be able to provide or consent given by a parent or guardian (if age \<18 years) or other authorised person

Exclusion criteria

Exclusion Criteria:

  1. to receiving IVIG as a treatment
  2. Current active acute rejection (≤ 3 months prior)
  3. Treating clinicians would regard as unsafe to be enrolled
  4. Limited (\< 12 months)
  5. Receiving Belatacept as part of their protocol
  6. Currently undergoing or who have previously received, viral-specific T-cell therapy for BK viremia
  7. Prior infection and treatment for BKPyV-Viremia
  8. Received IVIG treatment in the past with last IVIG treatment \< 4 weeks prior to randomisation
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. Composite ordinal outcome based on all cause death, allograft loss, eGFR decline, acute allograft rejection or BKV load > 1000 copies/mL, and immunosuppression load.

    All participants will be allocated a rank at 12 weeks between rank 5 (worst) and rank 1 (best). The primary comparison of interest is between participants randomised to intravenous immunoglobulin (IVIG) and participants randomised to the control arm. Outcome measures include: Rank 5 - all cause death, allograft loss, eGFR decline ≥10mls/min 1.73². Rank 4 - acute allograft rejection or BK viral load to \>1000 copies/mL. Ranks 3, 2, and 1 - the degree of immunosuppression reduction relative to baseline immunosuppression.
