About this study

International multicenter open-label single-arm confidence-interval-estimation based Phase II clinical trial, aiming to estimate a plausible range of the proportion of patients experiencing efficacy failure in the population, to provide evidence for efficacy and safety of the induction regimen with rATG and infliximab and a go/no go rule for further clinical development.

Read the detailed description

A total of 75 patients will receive the proposed induction regimen, with expected 68 completers accounting for drop-outs and non-compliances with the protocol. If up to 27 out of the 68 completers experience efficacy failure, a progression into a larger trial will be considered justifiable. If the number of patients experiencing efficacy failure is between 28 and 34 out of 68, the merits of a larger non-inferiority design will be considered depending on the risk/benefit assessment. If more than 34 out of the 68 completers experience efficacy failure, a progression into a larger trial would be considered unjustifiable. 1st kidney transplant recipients (low risk: PRA/cPRA < 20%, no DSA) will receive short rATG induction (2x1.5 mg/kg) given perioperatively and on first postoperative day. All patients will receive one shot Infliximab mAb at day 2. Since POD1, maintenance IS consists of Tac and tapered steroids therapy. All patients will be followed up for one year.

At the POD 0 the first rATG dose (1.5mg/kg) will be given according to the local practice and Methyprednisolon 500mg will be given before reperfusion. At the POD 1 patients will receive methylprednisolon 500mg i.v. followed by second rATG dose (1.5mg/kg). Infliximab 5mg/kg b.w. will be given in slow infusion on POD2. Tacrolimus will be given the first dose before surgery at dose 0.1 mg/kg and next from POD1 at 0.2mg/kg/day and doses adjusted according to blood trough levels (10-15 ng/mL, POD1-POD13, 5-8ng/mL POD 14-90, 4-6ng/mL POD >90. Prednison (or appropriate dose of methylprednisolone) will be initiated POD 2 at a dose of 20mg/day and slowly tapered down to 5 mg at the POD 7 (POD2: 20mg, POD3: 15mg, POD4-5: 10mg, POD6-7: 7,5mg, > POD7: 5mg).

    • Normal
    • Antibody mediated rejection
    • Borderline
    • T cell mediated rejection:

    Type IA: cases with significant interstitial infiltration (> 25% of parenchyma affected, i2 or i3) \& foci of moderate tubulitis (t2) Type IB: cases with significant interstitial infiltration (> 25% of parenchyma affected, i2 or i3) \& foci of severe tubulitis (t3) Type IIA: cases with mild to moderate intimal arteritis (v1) Type IIB: cases with severe intimal arteritis comprising > 25% of luminal area (v2) Type III: cases with transmural arteritis or arterial fibrinoid change \& necrosis of medial smooth muscle cells with accompanying lymphocytic inflammation (v3) Chronic allograft arteriopathy

    Measured: 12 month

  10. Health-related quality of life using SF-36v2 questionnaires at baseline (pre Transplantation), Month 1, Month 3, Month 6, and Month 12

    The SF-36v2 provides scores for each of the eight health domains and psychometrically-based physical component summary (PCS) and mental component summary (MCS) scores SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.

    The eight sections are: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, mental health

    Measured: baseline (pre transplantation), Month 1, Month 3, Month 6, and Month12

  11. Assessment of patient-specific resource consumption using a trial specific questionnaire at initial discharge, Month 3, Month 6, Month 12, and in cases of repeated hospitalization

    The questionnaires capture relevant apsects of resource consumption:

    • In which ward(s) a patient was hospitalized
    • Additional services (diagnostics / procedures / operations)
    • Potential dialysis procedures (past and expected frequency in the future)
    • Potential outpatient visits and the services consumed
    • Employment status and potential depency on care-giving The completion requires a review of inpatient records. Part II and Part III also require a short interview with the patient about potential outpatient visits during the study period, their employment status, and potential depedency on care-giving.

    Measured: initial discharge, Month 3, Month 6, Month 12, and in cases of repeated hospitalization

  12. Health-related quality of life using EQ5D-5L questionnaires at baseline (pre Transplantation), Month 1, Month 3, Month 6, and Month 12

    EQ-5D is a standardized instrument for measuring generic health status. It has been widely used in population health surveys, clinical studies, economic evaluation and in routine outcome measurement in the delivery of operational healthcare.

    The EQ-5D-5L is a Patient Reported Outcome (PRO) instrument that can generally assess the quality of life of patients, regardless of their disease, over 6 questions. It also includes a vertical EQ visual analog scale (EQ VAS, 0-100 points) and a descriptive EQ-5D-5L system, which considers the following 5 dimensions or subscales over 5 levels or possible answers.

    dimensions: mobility, self-sufficiency, General Activities, Pain / Physical complaints, fear / dejectedness levels: Level 1: No problems/ No pain/ Not afraid; Level 2: Slight problems/ Slight pain/ A little anxious; Level 3: Moderate problems/ Moderate pain/ Moderate anxiety; Level 4: Major problems / Severe pain/ Very anxious; Level 5: Not able to/ Extreme pain/ Extremely anxious

    Measured: baseline (pre transplantation), Month 1, Month 3, Month 6, and Month12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Antithymocyte Immunoglobulin (Rabbit) in people with Renal Transplant Rejection, run by Prof. Dr. Petra Reinke at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite endpoint of efficacy failure [(treated biopsy-proven acute rejection, graft loss, death, or loss to follow-up) and renal function (estimated glomerular filtration rate)] of the induction regimen (time frame: 12 months post transplantation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04114188, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2021.
