Brief Summary

The smartNTx trial: Prospective, randomized controlled trial (RCT) to investigate additional interventional telemedical management versus standard aftercare in kidney transplant recipients (KTR). STUDY PURPOSE: To demonstrate that additional interventional telemedical management will lead to a higher chance for long-term graft survival, increase adherence, quality of life (QoL), and reduce complications and healthcare costs after kidney transplantation.

Study Arms (2)

Intervention group "Additional telemedical management"

EXPERIMENTAL

Patients in the interventional arm will receive a predefined additional telemedical management including regular telemedicine visits and automatic data transfer (e.g. vital signs, well-being, medication plan laboratory data and chat) between the patient at home and KTC through a certified smartphone application.

Combination Product: Additional interventional telemedical management

Control group "Routine posttransplant aftercare"

NO INTERVENTION

Patients in the control group will receive routine posttransplant aftercare.

Interventions

Predefined additional telemedical management including regular telemedicine visits and automatic data transfer (e.g. vital signs, well-being, medication plan laboratory data and chat) between the patient at home and KTC through a certified smartphone application.

Eligibility Criteria

Age1 Year - 99 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Ability to use a smartphone or tablet or with help of someone close by
  • For children \< 12 years parents have to take over the use of the smartphone
  • Patients who are willing and able to participate in the study and from whom written informed consent has been obtained prior to study participation or pediatric patients with parenteral consent
  • Ability to communicate in German or English
  • Adequate and stable renal function (eGFR \> 30 ml/min, Proteinuria \< 1g/g creatinine) eGFR will be determined according to CKD-EPI for adults \[81\] or Schwartz formula for children \[82\]

You may not qualify if:

  • Patient with mental dysfunction or inability to comply with the study protocol or pediatric patients whose parents cannot comply with the study protocol
  • Any significant diseases or clinically significant findings, including psychiatric and behavioral problems, medical history and/or physical examination findings that would in the opinion of the investigator preclude the patient from participating in the study

  • Participation in any other interventional clinical trial less than 1 month before participation in this study
  • Patients who have been institutionalized by official or court order
  • Patients with a combined kidney transplant or multi-organ recipients (other solid organ (e.g. pancreas) or bone marrow)
  • Presence of DSA with MFI \> 1000 at time of transplantation
  • Recurrence of underlying kidney disease (e.g. focal segmental glomerulosclerosis (FSGS) or atypical hemolytic uremic syndrome (aHUS)
  • Patient with active malignancy post-transplant with the exception of local, non-invasive, fully excised, cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma, or cervical carcinoma in situ
  • Patients with clinically symptomatic congestive heart failure (CHF) or symptomatic coronary artery disease
  • Patients with documented (either by serology and/or nuclear acid testing (NAT) clinically active infections (e.g. with a known hepatitis B (HBV), hepatitis C (HCV), HIV, CMV or BK virus infection).
