More than one million people in the United States today are fighting blood cancer. While a traditional allogeneic stem cell transplant has been the best hope for many, the transplant itself can prove fatal or lead to serious conditions, such as graft vs. host disease. Orca Bio is a late-stage biotechnology company redefining the transplant process by developing next-generation cell therapies with the goal of providing significantly better survival rates with dramatically fewer risks. With our purified, high-precision investigational cell therapies we hope to not only replace patients' blood and immune systems with healthy ones, but also restore their lives.
We operate a dedicated clinical manufacturing facility in Sacramento, CA (3400 Business Drive), which has historically served as the foundation for producing our high-precision cell therapy products. This site plays a critical role in advancing our clinical pipeline and ensuring the consistent, reliable supply of therapies for patients participating in our trials.
