Clinical Trial Summary

Patients undergoing kidney transplantation alone (either de-novo or re-transplant) at a participating hospital are routinely surveyed with interval blood tests as part of standard post-operative care through outpatient consultation. These tests include serum creatinine, blood sugar as well as DSA testing at various intervals. The ability to screen patients to better identify those who may be at risk of developing an adverse event using AlloSure cfDNA is likely to be advantageous, with the potential to improve graft survival and outcomes for transplant patients. The addition of AlloSure to the interventional group will be the focus of this study. Patients will have quarterly AlloSure cfDNA testing (every 3 months) and DSA as part of their post-transplant surveillance for a period of 5 years.Participants will attend outpatient visits/follow-up visits as part of their standard care, these will include appointments where they will have blood tests taken as part of post-transplant surveillance. For AlloSure cfDNA and DSA, blood will be taken quarterly.

Eligibility

Inclusion Criteria:

• Participants with single kidney transplant (de-novo or re-transplant) who are = 6 months and = 36 months post-transplant. Participants and will need to have a draw in this time period .

• Participant is willing and able to give informed consent for participation in the trial.

Exclusion Criteria:

• Participant who is pregnant, lactating or planning pregnancy during the trial.

• Significant hepatic impairment (determined by the PI).

• Scheduled elective surgery or other procedures requiring general anaesthesia during the trial.

• Participant with life expectancy of less than 6 months, or inappropriate for diagnostic monitoring through regular blood sampling.

• < 6 months and > 36 months post-transplant

• Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial.

• Participants who have participated in another research trial involving an investigational product in the past 12 weeks.

• Multi-organ transplant (e.g., Kidney-Pancreas).

Related Conditions & MeSH terms

• Kidney Transplant Rejection

Intervention

Device:
• AlloSure
AlloSure is an analytically validated targeted next-generation sequencing (NGS) assay that uses single-nucleotide polymorphisms (SNPs) to measure the fraction of dd-cfDNA in transplant patients without the need for genotyping either the donor or the recipient.8
