Ampio to request approval from the FDA for the treatment of pain due to severe osteoarthritis of the knee.
ENGLEWOOD, Colo., June 30, 2016 /PRNewswire/ — Ampio Pharmaceuticals, Inc. (NYSE MKT: AMPE) announced today the results of the Ampion™ PIVOT clinical trial as well as a comprehensive analysis that integrates trial data from three single injection studies that will be presented to the FDA.
The PIVOT trial, which included 480 patients, was a double-blind saline-controlled phase III clinical trial performed in 20 sites across the US to examine the safety and efficacy of Ampion™ intra-articular injection in patients with pain due to osteoarthritis (OA) of the knee. The primary endpoint was the change in WOMAC A pain at week 12 as compared to saline. Additional analyses included adverse events (AEs), Patient Global Assessment (PGA), and responder status defined as 20% improvement in pain at week 12.
Ampion™ was demonstrated to be safe and well-tolerated with no drug-related serious AEs and an overall AE rate that was similar in the Ampion™ and saline groups. OA severity was defined by the Kellgren Lawrence scale (KL). Ampion™ improved WOMAC A pain significantly over baseline in all KL grades (KL 2: 52%, KL 3: 36%, and KL 4: 33% reductions in pain) but the primary end point was not met. The Company observed the largest differentiation between Ampion™ and saline in the most severe OA patients (KL 4), where no available non-surgical therapy exists. KL 4 patients have been historically excluded from knee OA trials because of the advanced stage of their condition.
Ampio to seek FDA approval
A comprehensive analysis that integrates trial data from three single injection studies demonstrates patients with KL 4 severity have significant benefit with Ampion™ over saline in more than 400 patients. The analysis showed statistically significant improvement:
WOMAC A pain (p = 0.016)
Patient Global Assessment (p = 0.001)
Responder status (p = 0.006)
Safety data will be presented to support the clinical benefit, as there were no drug-related safety issues observed.
Mr. Macaluso, Ampio’s CEO stated, “Ampio has the opportunity to provide treatment where there is a clear unmet medical need. Even though we did not meet the primary end point in the PIVOT study, we are pleased with the consistent effect Ampion™ demonstrated in all of our clinical trials. Ampio is requesting a meeting with the FDA to present our data in support of Ampion™.”
Ampio will host a conference call at 4:30pm ET on Tuesday, July 5th. Participants are invited to dial in using the instructions as follows:
