Study summary

This study evaluates the safety and tolerability of Renaparin in adult patients receiving a deceased donor kidney treated ex-vivo with Renaparin prior to transplantation. Half the patient group will receive a kidney treated with Renaparin, while the other half of the patient group will receive a kidney treated with placebo.

Read the detailed description

Kidney transplantation is the last resort for end-stage renal disease (ESRD). A key problem after transplantation is Delayed Graft Function (DGF). Short term, DGF will result in patients being put on dialysis in the immediate time-period after transplantation. In the longer perspective DGF is associated with increased risk of graft failure, thus decreasing the efficacy of the kidney transplantation.

Renaparin is a new product under development for the prevention of DGF in association with kidney transplantation. The product binds to the kidney vascular endothelium and its pharmacological effect is based on a local and effective presentation of heparin. Renaparin is administered ex vivo to the kidney by adding it to the preservation solution during Hypothermic Machine Perfusion (HMP) prior to transplantation.

Inclusion criteria

Organs:

  • Kidney must come from a deceased donor above 18 years of age
  • The regular protocols for organ donation according to Swedish law can be followed

Patients:

  • Male and female patients 18 - 75 years of age.
  • Ability to provide written .
  • Mentally stable and able to comply with the procedures of the study protocol
  • Patient has been listed for kidney transplantation from a deceased donor at the clinical sites included in this study.
  • Negative crossmatch test prior to transplantation and no existence of donor-specific antibodies
  • Receiving first or second renal transplantation

Exclusion criteria

Exclusion Criteria:

Organs:

  • Organs from donors deceased due to cardiac death.
  • Organs which have not been adequately perfused during HMP, as judged by the transplantation surgeon on call.

Patients:

  • Use of an drug or other investigational treatment, that could interfere with the outcome of the present trial, in the 30 days' period before Study Day 1
  • Increased risk of thrombosis (ex. homozygous APC-resistance) or bleeding (>1.5)
  • Anticoagulant treatment with Warfarin for indication unrelated to the kidney transplantation
  • History of heparin-induced thrombocytopenia (HIT)
  • History of or positive for , , or
  • History of oncological within the last five years, except excised squamous or basal cell carcinoma of the skin
  • Scheduled to undergo multi-organ transplantation or dual kidney transplantation
  • Current drug and/or alcohol abuse
  • Known fish allergy
  • History or presence of a medical condition or disease or psychiatric condition that in the investigator's assessment would place the patient at an unacceptable risk for study participation
  • Lactating or pregnant women or women who intend to become pregnant
  • Women of , defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of during study treatment. Acceptable birth control methods are those with a failure rate of less than 1% per year when used consistently and correctly. Such methods include (in "Recommendations related to contraception and pregnancy testing in clinical trials", supplied from www.hma.eu/):

    1. Combined (estrogen and progestogen containing hormonal contraception associated with inhibition of ovulation

      • oral
      • intravaginal
      • transdermal
    2. progestogen-only hormonal contraception associated with inhibition of ovulation

      • oral
      • injectable
      • implantable
    3. intrauterine device
    4. intrauterine hormone-releasing system
    5. bilateral tubal occlusion
    6. vasectomized partner
  • Patients who the investigator considers not eligible to give
  • Presence of -based evidence of acute myocardial infarction, unstable angina, decompensated heart failure, third degree of heart block or cardiac arrhythmia associated with hemodynamic stability
  • Patients with any condition or any circumstance that in the opinion of the investigator would make it unsafe to undergo a kidney transplantation
Terms in these criteria, in plain language(10)

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 1, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
