Building on a decades-long legacy in transplantation, Sanofi is dedicated to redefining outcomes for patients at every stage of their journey. We partner with patient communities, clinicians and advocacy groups to advance science, expand access and champion holistic care. Today, our commitment extends from solid organ transplantation to addressing complex conditions associated with bone marrow/stem cell transplantation, like chronic graft-versus-host disease (cGVHD). Through innovation and real-world applications, our mission is to protect the promise of transplant.

Kidney Transplantation:
94,000+
people on the national transplant waiting list need a kidney. 1
3-5
years average wait time for a deceased donor kidney. Black and Hispanic patients may wait even longer. 2-3
13
people die each day waiting for a kidney. 4
Chronic Graft-Versus-Host Disease:
~50%
of patients develop cGHVD after receiving an allogeneic (donor-derived) stem cell transplant.5
~10,000
people receive an allogeneic bone marrow/stem cell transplant each year in the U.S. and could be at risk for developing cGVHD.6,7,8
#1
cGVHD is the leading cause of late chronic illness and death after an allogeneic transplant.9

The Gift of Life Through Transplant
Of the 94,000+ patients in the U.S. on the kidney transplant waitlist, many are bound to dialysis machines for several hours a week and may wait years for a match. Kidney donation offers more than just a procedure—it’s a second chance at life.
Every 10 minutes, a new name is added to the waiting list, while 13 lives are lost every day waiting for a kidney.10 Every minute counts.
But there is hope. A kidney transplant from a deceased or living donor can transform someone’s life. Successful transplantation can free patients from the burden of dialysis, offering a path away from the machine and toward a future defined by possibility, not limitation.
At Sanofi, we’re committed to supporting this transformation. Discover how Sanofi partners with the transplant community and highlights these transplant heroes:

Understanding cGVHD and Its Impact
Chronic graft-versus-host disease (cGVHD) is a serious complication that can occur after a bone marrow or stem cell transplant. It happens when a donor’s new immune cells (the graft) mistake the recipient’s body (the host) as foreign and attacks healthy tissue.
The impact can be systemic and debilitating. cGVHD can turn recovery into an everyday struggle. For patients, this means navigating an unpredictable “new normal”—facing not only painful physical symptoms but also the heavy emotional toll of living with a complex, long-term condition.11 At Sanofi, we are dedicated to redefining survivorship—shifting the focus from simply surviving to living in authenticity.
