Brief Summary

Since the start of the COVID-19 pandemic, the approach to solid organ transplantation has evolved. Transplants using organs (excluding lungs) from COVID-19-positive donors have shown short-term safety, but there is limited data on recipients who are SARS-CoV-2 positive. Currently, kidney transplants in such recipients are delayed until symptoms resolve and a negative PCR is preferred, despite the risks of prolonged dialysis and increased cold ischemia time.

Recent data from the Omicron era suggest that early antiviral treatment may reduce complications. Immunosuppressive therapy might even help mitigate severe inflammatory responses. The proposed study aims to show that kidney transplantation can be safely performed in asymptomatic or mildly symptomatic COVID-19-positive recipients who begin antiviral treatment (remdesivir) within 24 hours before transplant and continue for 10 days. This could reduce waiting times and improve outcomes.

Remdesivir is an antiviral safe for use in patients with low kidney function, including those on dialysis or post-transplant, with minimal side effects. The hypothesis is that this treatment strategy can prevent progression to severe COVID-19 and allow safe transplantation

Patients with end-stage kidney disease that are included on the local kidney transplant waiting list who get an offer of a compatible organ and, subsequently, have a transplant procedure scheduled in the next 24 (+/-) 12 hours, or patients with end-stage kidney disease that are planned to receive a non-cadaveric donor kidney transplant on the following 5 days.
  3. Have a positive SARS-CoV-2 nasopharyngeal PCR or RAT within 5 days prior to transplant surgery.
  4. Have previously received at least three SARS-CoV-2 vaccine doses, with a minimum time elapsed of 3 months since the last dose received.
  5. Are asymptomatic or have mild acute COVID-19 symptoms during the previous 5 days (headache, sore throat, cough, chest pain, nausea, diarrhea, fatigue, loss of smell or taste, myalgia) excluding fever in the previous 48 hours (>38ºC) or shortness of breath.
  6. Post-menopausal or fertile females (females who are not surgically sterile or postmenopausal defined as amenorrhea for >12 months) that agree to avoid pregnancy during the study. If sexually active fe-male; using highly effective contraceptive methods (hormonal contraception, intra-uterine device (IUD), or anatomical sterility in self or partner*) while on study treatment. All female volunteers must be willing to undergo urine pregnancy tests at time of enrollment.

  9. Active liver disease with AST or ALT >3 ULN, Total bilirubin ≥2 × ULN (for Gilbert's syndrome, direct bilirubin >ULN is exclusionary) within the past 3 months, or liver function impairment with Class B or C per Child Pugh classification.
  10. Suspected or confirmed concurrent active respiratory infection other than COVID-19 that may interfere with the evaluation of response to the study intervention.
  11. Any comorbidity requiring hospitalization and/or surgery within 7 days prior to study entry, or that is considered life threatening within 30 days prior to study entry, as determined by the investigator.
  12. Prior participation in this trial.
