World Kidney Day: Top 5 Breakthroughs in Kidney Disease Treatment

Chronic kidney disease (CKD) is an escalating global health challenge, impacting over 35 million individuals in the United States and an estimated 100 million across Europe. Despite its widespread prevalence, CKD remains underdiagnosed until its advanced stages, leading to severe complications, including kidney failure, cardiovascular disease, and increased mortality.

However, recent scientific and medical advancements are transforming the landscape of nephrology, offering new therapeutic avenues and improved patient outcomes. From regenerative medicine and bioengineered organs to precision gene therapies and novel pharmacologic interventions, innovation is reshaping the future of kidney disease treatment.

In recognition of World Kidney Day, we highlight five groundbreaking breakthroughs that are revolutionizing kidney care and bringing new hope to millions of patients worldwide.

First Genetically-Edited Pig Kidney Transplant in a Living Human

On March 16, 2024, Massachusetts General Hospital achieved a historic milestone by successfully transplanting a gene-edited pig kidney into a living patient, Rick Slayman, who was suffering from end-stage kidney disease. Utilizing CRISPR-based genetic modifications, the pig kidney was engineered to enhance human compatibility and minimize immune rejection.

Key Scientific and Clinical Advancements:

• First gene-edited pig kidney transplant in a living human (prior xenotransplants were conducted only in brain-dead patients).
• The transplanted organ demonstrated immediate and sustained functionality, establishing xenotransplantation as a viable alternative for organ replacement therapy.
• Despite Slayman’s passing seven weeks post-surgery due to cardiac complications, no signs of organ rejection were observed, marking a pivotal success in xenotransplantation research.
• The success of this procedure has accelerated regulatory approvals, with the FDA greenlighting multi-patient xenotransplantation trials in 2025 (United Therapeutics Corporation, eGenesis).

Why It Matters for Kidney Patients:

• Addresses the global organ shortage, with over 92,000 patients currently awaiting kidney transplants in the U.S. alone.
• Reduces dependence on dialysis, improving quality of life and long-term survival rates.
• Establishes a foundation for xenotransplantation as a mainstream therapeutic option.

FDA Approval of Ozempic for Chronic Kidney Disease (CKD) Progression

On January 28, 2025, the FDA granted approval for Ozempic (semaglutide) as the first GLP-1 receptor agonist indicated for reducing the risk of kidney disease progression, kidney failure, and cardiovascular mortality in patients with type 2 diabetes and CKD.

Key Clinical Findings (FLOW Phase 3b Trial):

• 24% reduction in kidney disease progression, kidney failure, and cardiovascular death vs. placebo.
• Trial was terminated early due to overwhelming efficacy, underscoring its transformative impact on CKD management.
• Expands nephrology treatment options beyond SGLT2 inhibitors and RAAS blockers.

Why It Matters for Kidney Patients:

• Delays CKD progression, potentially preventing the need for dialysis or transplantation.
• Reduces cardiovascular mortality, a major cause of death in CKD patients.
• Enhances therapeutic strategies for the 40% of type 2 diabetes patients who develop CKD.

HIV-Positive Kidney Transplants: A Safe and Effective Option

A landmark study from Johns Hopkins Medicine has provided long-term clinical validation that kidney transplants between HIV-positive donors and recipients are as safe and effective as transplants from HIV-negative donors.

Key Scientific and Policy Implications:

• First large-scale study demonstrating comparable survival and graft success rates between HIV-positive and HIV-negative transplant groups.
• No significant differences in organ rejection, graft failure, or mortality.
• Findings support the expansion of donor eligibility, potentially increasing the available donor pool.
• Results could drive policy changes, increasing organ accessibility for HIV-positive patients with end-stage kidney disease.

Why It Matters for Kidney Patients:

• Expands transplant eligibility for HIV-positive patients.
• Shortens organ wait times, addressing critical shortages.
• Improves long-term survival and quality of life.

Awake Kidney Transplantation: Redefining Recovery Standards

On June 24, 2024, Northwestern Medicine performed its first-ever awake kidney transplant, utilizing regional spinal anesthesia instead of general anesthesia. This innovative approach significantly reduced post-surgical risks and accelerated recovery.

Key Clinical Advancements:

• First successful awake kidney transplant.
• Eliminated general anesthesia risks, making transplantation safer for high-risk patients.
• Enabled rapid post-operative mobilization, with the patient discharged in less than 24 hours (vs. the standard 2-3 days).

Why It Matters for Kidney Patients:

• Offers a safer alternative for patients with anesthesia-related complications.
• Accelerates recovery, improving post-operative outcomes.
• Potential to redefine transplant protocols, increasing procedural accessibility.

AAV Gene Therapy: A Paradigm Shift in Kidney Disease Treatment

A breakthrough study in Nature Communications has pioneered the development of adeno-associated virus (AAV) gene therapy for targeting renal tubules and podocytes—critical structures in kidney function. This innovation holds transformative potential for genetic kidney disorders and CKD progression.

Key Scientific Innovations:

• First kidney-optimized AAV vector (AAV-KP1) for targeted gene therapy.
• Demonstrated high-efficiency transduction of renal tubules while minimizing liver toxicity.
• Successfully bypassed pre-existing anti-AAV immunity using localized renal pelvis injection.
• Holds promise for treating genetic kidney diseases (e.g., Alport syndrome) and chronic kidney conditions.

Why It Matters for Kidney Patients:

• Potential to slow CKD progression, reducing long-term dialysis dependence.
• Expands treatment options for genetic kidney diseases.
• Minimizes off-target effects, enhancing safety compared to systemic gene therapies.
