Ampio Announces Top-Line Results of the Double-Blind Multiple Intra-Articular Injections (STRUT) Study of Ampion™ in Patients with Moderate to Severe Osteoarthritis of the Knee

ENGLEWOOD, Colo., Feb. 25, 2015 /PRNewswire/ -- Ampio Pharmaceuticals, Inc. (NYSE MKT: AMPE) today announced results of the double-blind, multiple injection, vehicle controlled STRUT study (N=40) at 20 weeks.

The forty patient randomized (1:1) phase of the STRUT study was conducted to assure that multiple injections of Ampion™ were safe and effective.  Each patient received three 4 mL intra-articular injections of Ampion™ or saline at baseline, 2 weeks and 4 weeks. There were no drug related serious adverse events reported during the 20 weeks of this trial; the top-line results are as follows:

• WOMAC A: The primary endpoint that is required for FDA approval, WOMAC A pain score, improved by 64% from baseline to 20 weeks. Ampion™ improved by -1.41 (0.81) compared to saline vehicle control which improved by -0.85 (0.64), p=0.0231. 
• Responder Rate: Responder rate is defined as a change of at least 1 point in the WOMAC A pain subscale. Responder rate for Ampion™ was 79% compared to 47% of saline patients, p=0.0451.

Detailed results of the STRUT study will be published in peer reviewed journals and presented at scientific conferences.

Data for the larger, multi-site STRIDE study (similar design to STRUT study) is expected in second quarter 2015.
