Item 7.01 Regulation FD Disclosure

On March 29, 2016, Ampio Pharmaceuticals, Inc. (the “Company”) issued a press release announcing that enrollment is now complete in the PIVOT trial of Ampion^TM for the treatment of pain due to osteoarthritis-of-the-knee. A copy of the press release is furnished hereto as Exhibit 99.1.

The information contained in this Item 7.01 and Exhibit 99.1 to this report shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liability of that section, and shall not be incorporated by reference into any filings made by the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except as may be expressly set forth by specific reference in such filing.

Item 9.01 Financial Statements and Exhibits.

This Current Report on Form 8-K and Exhibit 99.1 contain forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements typically are identified by use of terms such as “may,” “project,” “should,” “plan,” “expect,” “anticipate” “believe,” “estimate” and similar words, although some forward-looking statements are expressed differently. Forward-looking statements represent our management’s judgment regarding future events and include statements regarding the Company’s expectations with respect to the Ampion™ PIVOT trial, as well as risks associated with clinical trials, expected results, regulatory approvals, and changes in business conditions and similar events. These forward-looking statements also include statements regarding the Special Protocol Assessment as well as the classification of Ampion™ as a novel biologic with 12 years exclusivity. Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, the Company can give no assurance that such expectations will prove to be correct. All statements other than statements of historical fact included in this Current Report on Form 8-K and in Exhibit 99.1 are forward-looking statements. Except as required by applicable law, the Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. The Company cannot guarantee the accuracy of the forward-looking statements, and you should be aware that the Company’s actual results could differ materially from those contained in forward-looking statements due to a number of factors, including the statements under “Risk Factors” found in the Company’s Annual Reports on Form 10-K’s and its Quarterly Reports on Form 10-Q’s on file with the Securities and Exchange Commission.
