Biostage Activated Mayo Clinic as The First Site for Clinical Trial in Severe Esophageal Disease


HOLLISTON, Mass., July 18, 2023 /PRNewswire/ -- Biostage, Inc (Formerly Known As Harvard Apparatus Regenerative Technology) (OTCQB: BSTG) ("Biostage" or the "Company"), a clinical-stage biotechnology company developing the technology to regenerate organs inside the body to treat severe diseases, including cancer, trauma and birth defects initially in the esophagus and the airway, today announced that it officially activated the site with Mayo Clinic for its clinical trial as to severe esophageal disease, being its first clinical trial in the United States.

"We are thrilled to announce the initiation of our first clinical study for our esophageal implant, marking an important milestone for Biostage," said Jerry He, Chairman and CEO of Biostage. "Our numerous preclinical studies have demonstrated our technology as an effective platform for tubular organ regeneration. We look forward to testing the esophageal implant in the clinics as we further our understanding of its potential benefits for patients. As a leader in the field of organ regeneration and regenerative medicine, we feel a strong sense of responsibility to act swiftly to bring better treatment for suffering patients as soon as possible," Jerry further emphasized.

Dr. Shunfu Hu, VP of Operations and Business Development, commented with his excitement, "After years of collaboration with the Mayo Clinic, we are thrilled that our innovative organ regeneration platform is undergoing clinical trial evaluation, ready to recruit patients in the US."

The Phase 1, first-in-human study approved by the FDA will evaluate both safety and efficacy in up to ten patients requiring the removal of up to 6 cm of their esophagus (including cancer, trauma or birth defects) at up to five hospitals in the U.S. The primary endpoint is the development of a continuous biological neo-conduit at three months following implantation.

Further details of the study are posted on

About Biostage

We are a clinical-stage biotechnology company developing regenerative-medicine treatments for disorders of the gastro-intestinal system and the airway resulting from cancer, trauma or birth defects. Our technology is based on our proprietary cell-therapy platform that uses a patient's own stem cells to regenerate and restore function to damaged organs. We believe that our technology represents a next-generation solution for restoring organ function because it allows the patient to regenerate their own organ, thus eliminating the need for human donor or animal transplants, the sacrifice of another of the patient's own organs or permanent artificial implants.

We conducted the world's first successful regeneration of the esophagus in a patient with esophageal cancer in August 2017. This surgery was performed by Dr. Denis Wigle, Chair of Thoracic Surgery at the Mayo Clinic. The results were published in the Journal of Thoracic Oncology Clinical and Research Reports in August 2021. The procedure demonstrated that our technology was able to successfully regenerate esophageal tissue, including the mucosal lining, to restore the integrity, continuity and functionality of the esophageal tube. 

Biostage has 13 issued U.S. patents, 2 issued in China and 2 orphan-drug designations which can provide seven years of market exclusivity in addition to any exclusivity granted by patents.
