Item 7.01 Regulation FD Disclosure.

On Tuesday, February 13, 2018 at 9:00 AM (Eastern Time), Biostage, Inc., or the Company, hosted a conference call with investors, or the Investor Call, during which the Company provided an update on recent events at the Company and discussed other matters relating to the business, including operations, plans and outlook. These updates included, among other things:

- An update regarding the compassionate use patient that received the first esophageal implant in May 2017 as part of a broader FDA approved compassionate use surgery. The 75 year old patient had a large tumor spanning his heart, lung, and esophagus. The surgery was performed to remove the tumor, repair the heart, one lung, and a section of the esophagus. Following the surgery, the patient was discharged and the hospital reported to the Company there had been clear signs of regeneration with respect to the esophageal implant. The Company was informed yesterday by the principle investigator, the patient’s surgeon, that after living for over eight months following the surgery, the patient had died. He stated that the cause of death was stroke, and that the stroke was unrelated to the Company’s esophageal implant. The principle investigator also informed the Company that a preliminary autopsy shows the Company’s esophageal implant resulted in a regenerated esophageal tube in the patient except for a very small (approximately 5mm) hole on the lateral wall that was right up against a synthetic graft inserted as part of the patient’s heart repair on the pericardium in that same surgery. The synthetic graft on the pericardium was not related to the Company’s esophageal implant product. The principle investigator also informed the Company that the esophageal regeneration in this patient was consistent with the regeneration previously observed in the Company’s large-animal studies.

A replay of the Investor Call, including any questions and answers that occurred on the Investor Call following the scripted portion, will be available for one week following the call and can be accessed during that period by dialing (877) 660-6853 (domestic) or (201) 612-7415 (international) with Conference ID #: 13676470.
