Descrição detalhada

This research study is for adults who are planning to have a kidney transplant from a living donor.

In Brief:

Those who have a transplant take immunosuppressive therapy to prevent the body from rejecting the transplanted organ. Rejection occurs when the body's defense system (immune cells) recognizes the transplant as a foreign object. These immune cells and the substances they produce can damage the transplanted kidney. It is important to prevent rejection episodes, so the kidney transplant lasts as long as possible.

Most transplant doctors in the United States give a combination of two or three drugs to prevent rejection. People with a transplant must take these drugs every day. Although kidney transplant recipients usually do well in the first five years after transplant, researchers want to find new ways to prevent rejection and avoid the side effects that the current drugs can cause.

This study will test a new combination of four drugs to evaluate whether this combination is safe for kidney transplant recipients:

  • lulizumab pegol (BMS-931699)
  • tocilizumab
  • belatacept and
  • everolimus.

Belatacept and everolimus are already approved for use as anti-rejection drugs in kidney transplant recipients. Lulizumab pegol and tocilizumab act on specific molecules (specifically CD28 and interleukin 6, respectively) on immune cells: these actions are different from how the older rejection drugs work.

Summary: This is a prospective multicenter open-label clinical trial of 10 living donor kidney transplant recipients. Safety of lulizumab pegol (BMS-931699) in the context of a novel immunosuppressive regimen (anti-thymocyte globulin (rabbit) (ATG), steroids,) Nulojix® (belatacept), Actemra® (tocilizumab), and Zortress®(everolimus)) will be assessed. Study participation involves a minimum of one year of follow-up post-transplant.

*** IMPORTANT NOTICE: *** The National Institute of Allergy and Infectious Diseases and the Clinical Trials in Organ Transplantation (CTOT) do not recommend the discontinuation of immunosuppressive therapy for recipients of cell, organ, or tissue transplants outside of physician-directed, controlled clinical studies. Discontinuation of prescribed immunosuppressive therapy can result in serious health consequences and should only be performed in certain rare circumstances, upon the recommendation and with the guidance of your health care provider.

Descrição da medida
Prazo
The Proportion of Participants Who Remain Free of Biopsy-proven Acute T-cell Mediated or Antibody-mediated Rejection (as Defined by Banff Criteria) at 6 Months Post-transplantation.
Prazo: 6 months post-transplantation

Acute T-cell mediated rejection was defined using the Banff 2007 criteria. Participants with a Banff grade of greater than or equal to 1A were determined to have met the endpoint. Severity is graded as 1A, 1B, 2A, 2B, or 3, with 1A being the mildest form of cellular rejection and 3 being the most severe form of cellular rejection. Antibody mediated rejection was defined as diffusely positive staining for C4d, presence of circulating anti-donor antibodies, and morphologic evidence of acute tissue injury. Clinical rejection occurring prior to 6 months, defined as treated rejection without biopsy confirmation was included as acute rejection with respect to the endpoint.
