Ampio Completes Enrollment in Pivotal Clinical Trial of AMPION™

ENGLEWOOD, Colo., March 29, 2016 /PRNewswire/ — Ampio Pharmaceuticals, Inc. (NYSE MKT: AMPE) announced today that enrollment is now complete in the PIVOT trial of Ampion™ for the treatment of pain due to osteoarthritis-of-the-knee (OAK).

Michael Macaluso, Ampio’s CEO explained: “The PIVOT trial is a randomized, placebo-controlled, double-blind study to evaluate the efficacy and safety of an intra-articular injection of AMPION in adults with pain due to osteoarthritis of the knee that was conducted in accordance with a Special Protocol Assessment (SPA) issued by the FDA. A Special Protocol Assessment (SPA) is a written agreement between the FDA and the sponsor company (Ampio Pharmaceuticals), which defines the clinical trial end-points required for approval and significantly reduces the risk of bringing a drug to market. This second pivotal trial is clinically identical to the previously successful Spring Study, which was confirmed by the agency as one of the two pivotal trials required for approval.  Our goal is to meet the clinical obligations for a novel biologic, a special designation that comes with 12 years of market exclusivity.

When we commenced the PIVOT Phase III Study in September 2015, we estimated the trial to require 484 patients. However the written guidance from the FDA required 464 patients, powered at 88%. The trial closed at 480 patients with approximately 60% of the patients already completing the 12-week period following dosing. Accordingly, we expect final results to be available mid-year 2016. A full description of the trial is outlined at:

About Osteoarthritis
Osteoarthritis is the most common form of arthritis, affecting over 27 million people in the United States. It is a progressive disorder of the joints involving degradation of the intra-articular cartilage, joint lining, ligaments, and bone. The incidence of developing osteoarthritis of the knee or hip over a lifetime is approximately 46% and 25%, respectively. Certain risk factors in conjunction with natural wear and tear lead to the breakdown of cartilage. Osteoarthritis is caused by inflammation of the soft tissue and bony structures of the joint, which worsens over time and leads to progressive thinning of articular cartilage. Other symptoms include narrowing of the joint space, synovial membrane thickening, osteophyte formation and increased density of subchondral bone.

We are developing compounds that decrease inflammation by (i) inhibiting specific pro-inflammatory compounds by affecting specific pathways at the protein expression and at the transcription level; (ii) activating specific phosphatase or depletion of the available phosphate needed for the inflammation process; and (iii) decreasing vascular permeability.
