As the Company anticipated, Biostage received questions from the FDA following its IND application in late October. Biostage provided preliminary responses to these questions and notified the agency that a complete response would follow. The FDA's November 27th message noted its understanding that additional time is needed to fully answer the agency's questions, and that the FDA will send a more detailed letter regarding the application's hold status within 30 days. The Company is working to finalize responses to the FDA questions.

About Biostage, Inc.

Biostage is a bioengineering company that is developing next-generation esophageal implants. The Company's Cellspan technology combines a proprietary, biocompatible scaffold with a patient's own cells to create an esophageal implant that could potentially be used to treat pediatric esophageal atresia and other conditions that affect the esophagus. The Company's Cellspan esophageal implant leverages the body's inherent capacity to heal itself. The CEI is implanted as a cellular 'living tube' delivered via a temporary removable scaffold cell delivery device. The CEI facilitates regeneration of esophageal tissue and triggers a positive host response resulting in a tissue-engineered neo-conduit that restores continuity of the esophagus. These implants have the potential to dramatically improve the quality of life for children and adults. At Biostage, we believe the future of medicine has been inside us all along.
