GREENWOOD VILLAGE, Colo., Feb. 25, 2013 /PRNewswire/ -- Ampio Pharmaceuticals, Inc. (NASDAQ :AMPE ) announced today that it's Phase III clinical study of Ampion™ for the treatment for osteoarthritis of the knee will include a dose-escalation run-in study as recommended by the FDA.
Dr. Vaughan Clift, Ampio's Chief Regulatory Officer, explained "In the Australian trial, a single 4 ml dose provided promising results from the Ampion™ treated patients suffering from osteoarthritis. This run-in portion of the Phase III trial that will be launched in the US is designed primarily to determine if the 4 mL treatment could be improved by administering a 10 ml volume of Ampion™, the volume commonly injected into the knee with other therapeutic agents."
Dr. Clift further noted "Accordingly, the Company has modified the original study design to accommodate the FDA recommendations and submitted this upgraded IND study protocol for clearance to begin treating patients. A Clinical Research Organization (CRO) has been engaged and multiple clinical sites have been selected that are ready to enroll patients in the study. The dose ranging run-in study will commence shortly and will include 320 patients in total comparing 4 ml to 10 ml injection using the WOMAC pain scale."
Michael Macaluso, Chairman and CEO of Ampio, commented "The FDA has been very helpful by recommending a single run-In study to begin our Phase III pivotal trial that will provide us deeper understanding of the treatment effect and an optimized dose that may well reduce the patient requirement, and the associated time and costs as the number of combined patients in the run-in/phase III study may be significantly less than the 1600 patients planned for the two, phase III studies in the original IND application."
About the Australian Ampion™-In-Knee (AIK) trial
In May 2012, Ampio announced the full results of the Ampion™-In-Knee (AIK) trial which demonstrated prolonged and sustained pain relief in osteoarthritis following Ampion™ treatment. There was a statistically significant improvement in pain relief at 84 days following a single injection of Ampion™ compared to placebo and overtime. The treatment was well tolerated with no significant adverse events and no minor adverse events in the Ampion™ group compared to the placebo group.
Ampion™ is a non-steroidal anti-inflammatory biologic that has the potential to be used in a broad array of inflammatory conditions and autoimmune diseases. The active ingredient is aspartyl-alanyl diketopiperazine, referred to as DA-DKP, which is derived from two amino acids from human albumin and appears to have a significant role in the homeostasis of inflammation. Ampion™ is protected by composition of matter, use, and synthetic form patents. Ampio has published a number of studies and articles on the anti-inflammatory activity of DA-DKP.
Osteoarthritis (OA) is the most common form of arthritis, affecting 27 million people in the US.1 Symptomatic OA of the knee occurs in 10-13% of individuals over the age of 60.2 OA 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, narrowing of the joint space, synovial membrane thickening, osteophyte formation and increased density of subchondral bone.3 These changes eventually result in chronic pain and disability, and deterioration of the joint despite drug therapy may require eventual surgery of total joint replacement. Current drug treatment for OA of the knee relies on pain control with analgesics, and anti-inflammatory treatment with NSAIDs and intra-articular injections of steroids or hyaluronates. The current drug treatments have been shown to have mixed results and may have significant limitations due to various adverse effects such as gastrointestinal irritation and bleeding4.
