## Summary

FDA-cleared IND for CRISPR-edited pig kidney (ESKD Phase 1/2/3). First patient dialysis-free at 7+ months post-transplant. 69-gene-edited pig — most complex CRISPR ever.

## Company Overview

eGenesis is developing gene-edited pig organs for human transplantation — xenotransplantation — using a 69-gene CRISPR editing protocol that simultaneously knocks out pig genes that trigger human rejection, adds human immune tolerance genes, and eliminates porcine endogenous retroviruses. The company received FDA clearance for its IND for EIGEN-2784 (a gene-edited pig kidney) for end-stage kidney disease, and its first transplant patient remained dialysis-free at more than 7 months post-transplant — the longest reported survival for a xenotransplantation recipient.

The 69-gene edit represents the most complex CRISPR modification ever applied to a large animal, developed over a decade of research at Harvard Medical School. The clinical trial now enrolling is pivotal: if positive results are sustained, it would establish gene-edited pig kidneys as a viable alternative to human donor organs — addressing the chronic shortage of 100,000+ patients on the US kidney transplant waiting list, of whom 13 patients die each day awaiting a kidney.

eGenesis's approach is systematically addressing the three barriers to xenotransplantation: hyperacute rejection (pig galactose antigens), chronic rejection (human immune response), and the risk of porcine viral transmission (PERV elimination). The 69-gene protocol represents the most thorough published solution to all three barriers simultaneously, making eGenesis the most clinically advanced xenotransplantation program globally.

## Frequently Asked Questions

### What does eGenesis do?
Develops CRISPR-edited pig kidneys for human transplantation — 69 genetic modifications to prevent rejection, add human immune tolerance, and eliminate viral risks. FDA-cleared IND, patient dialysis-free 7+ months.

### What makes the 69-gene edit remarkable?
The most complex CRISPR modification ever applied to a large animal — simultaneously addresses all three xenotransplantation barriers: hyperacute rejection, chronic rejection, and porcine viral transmission.

### What is the clinical status?
FDA-cleared IND for EIGEN-2784. Phase 1/2/3 trial now enrolling. First patient dialysis-free at 7+ months — longest reported xenotransplantation survival.

### Why does xenotransplantation matter?
100,000+ patients on the US kidney transplant waiting list. 13 patients die per day awaiting a kidney. Gene-edited pig organs could eliminate the organ shortage entirely.

### What is eGenesis' UThrive program and clinical status?
eGenesis' lead program uses kidneys from pigs edited with 69 genetic modifications to remove porcine retroviruses, add human complement regulatory proteins, and modify pig-specific antigens that trigger human immune rejection. The company has conducted compassionate use cases of xenotransplantation in patients with end-stage renal disease who were not eligible for conventional transplant, with recipients surviving months with functioning pig kidneys — the longest xenotransplant survival times recorded.

### How does xenotransplantation address the organ shortage?
Over 100,000 people in the US are on the kidney transplant waitlist; 13 people die daily waiting for a transplant. Pig organs are anatomically similar to human organs and pigs are bred at sufficient scale to potentially eliminate the organ shortage entirely. eGenesis's multi-gene edited pigs could produce an effectively unlimited supply of transplantable organs — solving a public health problem that kills more Americans than most cancer types annually.

### What immune rejection challenges remain for xenotransplantation?
Even with 69 gene edits, chronic rejection remains a challenge — human immune systems mount T cell and antibody responses against remaining pig antigens over months to years. eGenesis's recipients typically require intensive immunosuppression similar to or exceeding conventional transplant protocols. The company is pursuing additional genetic modifications and potentially tolerance induction protocols to extend xenotransplant survival. Antibody-mediated rejection and accommodation (a form of immune adaptation) are active research areas.

### What is eGenesis' regulatory pathway to commercialization?
eGenesis is working with FDA on a regulatory framework for xenotransplantation — a novel category requiring new guidance on safety monitoring (particularly for porcine endogenous retroviruses, or PERVs), manufacturing standards for gene-edited pig breeding, and clinical trial design. The FDA issued xenotransplantation guidance updates in 2023 acknowledging the clinical progress. eGenesis expects to enter formal Phase 1 IND-approved clinical trials in the 2025-2026 timeframe after its compassionate use experience informs protocol design.
