Item 7.01.  Regulation FD Disclosure.

On April 13, 2017, InVivo Therapeutics, Inc. (the “Company”) posted an updated corporate presentation in the “Investor Relations” section of its website at www.invivotherapeutics.com.

Item 8.01.  Other Events.

On April 13, 2017, the Company announced that it intends to amend its protocol for The INSPIRE Study to include an additional arm (the “Benchmark Arm”) in order to gather baseline and outcome measures on thoracic, complete spinal cord injury patients.  The Company plans to include those patients who have presented at INSPIRE sites since January 1, 2016 but who were excluded from The INSPIRE Study because they did not meet all inclusion criteria or who presented before the sites opened or were enrolling patients.  The Company estimates that 20 to 40 additional patients will participate in the Benchmark Arm, and does not expect the Benchmark Arm to impact the timeline for The INSPIRE Study. The Company plans to submit the amended protocol to the United States Food and Drug Administration in the second quarter of 2017.
