Comparison Thymoglobulin® and Grafalon® (THYGRET)

July 6, 2020 updated by: University Hospital, Brest

Comparison Thymoglobulin® Versus Grafalon® in Renal Transplantation - Spiesser Group (Retro/Prospective Study) I

This is a prospective, multicenter, observational, non -interventional study with comparison with an historical cohort Investigators will compare the efficacy and safety of Thymoglobulin (Sanofi-Aventis) versus Grafalon (Neovii, previously ATG-Fresenius) in renal transplantation by evaluating patient survival, graft survival, delayed graft function, acute rejection, DSA occurrence and toxicities, various infections including CMV and BK virus incidence, MACE (major cardiac adverse event) and cancer.

Investigators will also compare cumulative treatment and follow up costs and other key criteria available in the ASTRE database.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective, multicenter, observational, non -interventional study with comparison with an historical cohort Investigators will compare the efficacy and safety of Thymoglobulin (Sanofi-Aventis) versus Grafalon (Neovii, previously ATG-Fresenius) in renal transplantation by evaluating patient survival, graft survival, delayed graft function, acute rejection, DSA occurrence and toxicities, various infections including CMV and BK virus incidence, MACE (major cardiac adverse event) and cancer.

Investigators will also compare cumulative treatment and follow up costs and other key criteria available in the ASTRE database.

Justification for a non-interventional study: in the study the medicinal products will be prescribed in the usual manner in accordance with the terms of the marketing authorisation. The assignment of the patient to the product is not decided in advance by a trial protocol but falls within current practice of the centre and the prescription of the medicine is clearly separated from the decision to include the patient in the study. No additional diagnostic or monitoring procedures are applied to the patients and epidemiological methods are used for the analysis of collected data.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients who have received or are receiving induction ATGs at the time of transplantation and whose data are collected from the ASTRE base in the 13 renal transplant centrers participating in the study.

Description

Inclusion Criteria:

  • For the Grafalon prospective group: all first 11-12 patients from the 13 transplant centres receiving Grafalon according to the local practice
  • For the Thymoglobulin group: a group of 130 patients matched for:

age (donor and recipient) gender indication (immunological indication versus DFG) CMV status

Exclusion Criteria:

  • Patient younger than 18 years old
  • Living donor
  • Donor after cardiac death (because the Maastricht 3 donors are authorized recently in France)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparison adverse events of the 2 ATGs and data collected thanks to the ASTRE database
Time Frame: During one year
All events: Death, graft loss, acute rejection, DGF, de novo DSA Severe infection (SAE), hematological adverse event (SAE), CMV infection, BK virus infection, MACE(major cardiac adverse event) and cancer
During one year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Recipient Efficacy (any adverse events)
Time Frame: During one year
comparison during the first year between the two groups for: patient and graft survival, delayed graft function, one year rate of acute rejection, occurrence od de novo DSA, renal function at one year (eGFR,MDRD)
During one year
Recipient Safety (any adverse events)
Time Frame: During one year
Comparison during the first year between the two groups for various infections (virus, bacteria, fungi), hematological adverse event (SAE or not)
During one year
Reconstitution of the T, and B cell populations
Time Frame: During one year
Reconstitution of the T, and B cell populations at D0, D7, M3, M12
During one year
