Efficacy of Belatacept in Reducing DSA

July 6, 2017 updated by: Paul Bolin, East Carolina University

An Exploratory, Open-label, Single Center Study to Assess the Efficacy of NULOJIX (Belatacept) in Reducing Donor Specific Human Leukocyte Antigen (HLA) Antibody (DSA) Strength in Maintenance Kidney Transplant Recipients

The primary objective of this study is to demonstrate that administration of belatacept in maintenance kidney transplant recipients may cause a reduction in Donor Specific HLA Antibody (DSA).

Study Overview

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

The aim of this study is to evaluate patients converted to belatacept in combination with Mycophenolate Mofetil (MMF) with corticosteroids with respect to their DSA titer. Patients in this study will be converted from their calcineurin inhibitor (CNI) to belatacept from baseline in an attempt to down-modulate antibody production by B-cells. Dosing will be calculated per prescribing information for dosing maintenance phase (5mg per kg every 28 days.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Recipients of cadaveric, living related or living unrelated kidney transplant with positive DSA titer (two positive tests) and enrolled within 6 months of DSA detection.
  • Patients with stable renal function. Stable renal function is defined as one serum creatinine (SCr) value that is +/- 10% of the baseline SCr within 3 months of enrollment (eGFR >/= 35 and </= 75 mL/min/1.73m^2).
  • Patients who are EBV seropositive
  • Males and females, 18-75 years of age;
  • Patients currently receiving mycophenolic acid (MPA) (CellCept daily or myfortic daily), cyclosporine or tacrolimus with corticosteroids as part of their immunosuppressive regimen
  • Patients willing to be converted to belatacept from cyclosporine or tacrolimus.
  • Females of childbearing potential must have a negative pregnancy test prior to enrollment. The test should be performed at baseline visit. Effective contraception must be used during the trial, and for 4 weeks following discontinuation of the study medication;
  • Patients who are willing and able to participate in the full course of the study and from whom written informed consent has been obtained.

Exclusion Criteria:

  • Multi-solid or cellular organ transplants (e.g. combined with pancreas, liver, islet, bone marrow), either concurrent or previous (with exception that a second kidney transplant is allowed);
  • Evidence of graft rejection or treatment of acute rejection within 14 days prior to Baseline visit;
  • Patients who have received any investigational drug within 4 weeks prior to study entry;
  • Patients with HLA identical
  • Patients who are Epstein-Barr virus (EBV) seronegative
  • Presence of clinically significant infection requiring continued therapy, chronic infection (e.g. HIV, Hep B and Hep C), malignancy (within last 5 years, except excised squamous or basal cell carcinoma of the skin), lymphoma or renal toxicity that would interfere with the appropriate conduct of the study;
  • Evidence of severe liver disease (incl. abnormal liver profile i.e. Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) or total bilirubin >/= 3 times ULN) or severe diarrhea or active peptic ulcer disease that would interfere with the appropriate conduct of the study;
  • Abnormal physical or laboratory findings of clinical significance within 2 weeks of inclusion which would interfere with the objectives of the study;
  • Patients with symptoms of significant somatic or mental illness or evidence of drug and/or alcohol abuse;
  • Patients receiving > 10 mg/day prednisone dose;
  • History of hypersensitivity to any of the study drugs or to drugs with similar chemical structures to belatacept;
  • Patients not making DSA antibodies;
  • Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test (local); females of childbearing potential who are unwilling to use effective study-approved contraceptives and who are planning to become pregnant; Sexually active fertile men must use effective birth control if their partners are women of child bearing potential;
  • Any other medical condition that, in the opinion of the site investigator based on recall or chart review would interfere with completing the study, including but not limited to visual problems or cognitive impairment.

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
Change of Donor Specific Antibodies (DSA)
Time Frame: one year
DSA levels will be measured using microbeads coated with Class I or Class II human leukocyte antigens (HLA) and read using a Luminex flow cytometer. Participants will be converted from their current Mycophenolate Mofetil (MMF) to once a month infusions of Belatacept.
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.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
