Biostage Announces Positive Preclinical Data of Cellspan™ Esophageal Implant Presented at the International Society for Stem Cell Research 2017 Annual Meeting

Cellspan Esophageal Implants utilize the Company's proprietary Cellframe™ technology and may offer improved outcomes for patients by potentially simplifying surgical techniques to reduce postoperative complications and improve quality of life, by prompting regeneration of the patient's own esophagus. Cellspan implants are intended to offer numerous advantages over standard surgical resection including: eliminating the use of the stomach or intestine to create a mock esophagus, reduced complications and improve post-surgical morbidity.

In November 2016, the Company's Cellspan Esophageal Implant was granted Orphan Drug Designation by the U.S. Food and Drug Administration ("FDA") to restore the structure and function of the esophagus subsequent to esophageal damage due to cancer, injury or congenital abnormalities.

About Biostage

Biostage is a biotechnology company developing bioengineered organ implants based on the Company's new Cellframe™ technology which combines a proprietary biocompatible scaffold with a patient's own stem cells to create Cellspan organ implants. Cellspan implants are being developed to treat life-threatening conditions of the esophagus, bronchus or trachea with the hope of dramatically improving the treatment paradigm for patients. Based on its preclinical data, Biostage has selected life-threatening conditions of the esophagus as the initial clinical application of its technology.

Cellspan implants are currently being advanced and tested in collaborative preclinical studies. Preclinical, large-animal safety studies, conducted in compliance with the U.S. Food and Drug Administration ("FDA") Good Laboratory Practice ("GLP") regulations, for the Company's Cellspan Esophageal Implant product candidate are ongoing, in support of Biostage's goal of filing an Investigational New Drug application ("IND") with the FDA in the third quarter of 2017. Upon IND approval, the Company plans to initiate its first-in-human clinical trials for its esophageal implant product candidate by the end of 2017.
