Ampio Provides Update on Osteoarthritis of the Knee (OAK) Program, Reiterates Compelling Data in Earlier Phase III Trials of Ampion in Severe OAK
Ampio Pharmaceuticals (AMPE) announced integrated data from four earlier clinical trials of Ampion for severe osteoarthritis of the knee (OAK). This analysis involved 585 patients and demonstrated significant pain reduction compared to saline at multiple intervals. The data highlights Ampion's efficacy, with reductions in pain of up to 38.1% at ten weeks. The FDA has agreed that one pivotal trial supports a future Biologics License Application (BLA). Despite COVID-19 delaying other trials, Ampio remains optimistic about upcoming results and aims to be the first novel OAK therapy in over 20 years.
- Significant pain reduction in severe OAK patients (up to 38.1% at ten weeks).
- Largest dataset (585 patients) demonstrating efficacy in severe OAK.
- FDA agreement on pivotal trial supporting future BLA submission.
- Ampion has proven safe with no serious adverse events reported.
- Ongoing delays in the Phase III AP-013 clinical trial due to COVID-19.
ENGLEWOOD, Colo., June 17, 2021 /PRNewswire/ -- Ampio Pharmaceuticals (NYSE American: AMPE), a biopharmaceutical company focused on the advancement of immunology-based therapies for prevalent inflammatory conditions, today reported newly integrated data from four of its earlier clinical trials with consistent inclusion, exclusion, and demographic populations utilizing Ampion for treating osteoarthritis of the knee (OAK). Data from these 585 patients categorized as severe (i.e., Kellgren-Lawrence grade 4, or KL 4) demonstrates Ampion's consistent and statistically significant clinical effect in the reduction of pain compared to saline at two, ten, and twelve-week intervals subsequent to intra-articular injection.
"These 585 KL 4 patients in our earlier trials represent the largest available and reported dataset of severe OAK patients to date, and the data analysis clearly show Ampion as the first therapy to demonstrate clinical efficacy in patients suffering from severe OAK," said Michael Macaluso, President and CEO of Ampio. "Severe OAK remains a critical unmet medical need. We have already secured one pivotal trial that the FDA has agreed we can use to file our Biologics License Application (BLA), and, while our latest Phase III AP-013 clinical trial in OAK had to be paused because of the COVID-19 pandemic, the high degree of efficacy seen in the integrated data for KL 4 patients from the previous four trials gives us confidence to expect a positive outcome when it comes time to unblind this study."
Top-line results from Ampio's AP-003-A, AP-003-B, and AP-004 trials were previously published in Orthopedics (Orthopedics. 2018; 41(1):e77-e83), which reflected a clinically and statistically significant reduction in pain at weeks ten and twelve following a single injection, compared to saline, using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale. In addition, Ampion showed a
Today's announcement integrates data from severe OAK patients who were enrolled in Ampio's AP-003-C Phase III clinical trial with the previously published results. The pooled data show an even greater statistical significance, with a reduction in pain of
Ampion has proven safe in thousands of enrolled and randomized patients, supporting repeat administration. No drug-related serious adverse events (SAEs) or treatment-related deaths have occurred, and the majority of adverse events (AEs) were unrelated to treatment. The incidence and severity of adverse events are similar for Ampion and saline, and the incidence of related AEs is far lower than that reported for existing therapies.
"Ampion is on track to become the first novel drug with unique mechanisms of action on the market for OAK in over 20 years. Ampion treatment has demonstrated consistent clinical efficacy in patients suffering from OAK across multiple trials, periods of time and clinical sites. In addition, the FDA has provided written confirmation that the AP-003-A study provides evidence of the effectiveness of Ampion" continued Macaluso. "We continue to remain confident the data from the suspended Phase III AP-013 trial will show similar safety and efficacy, but the decision whether to unblind this double masked, randomized controlled study or to continue adding patients ideally should be jointly decided with future potential partners."
About Osteoarthritis of the Knee (OAK)
According to a recent estimate published in The Lancet, around 650 million people worldwide suffer from osteoarthritis of the knee (OAK), an inflammatory, progressive, incurable disease characterized by elevated cytokines. Beyond being a mere quality of life issue, people who suffer from osteoarthritis have a significantly higher mortality rate than the general population.
Elevated levels of the cytokines TNFα and IL-12 are associated with pain and loss of function, while IL-1β and IL-6 are associated with disease severity. Ampion is the only therapy with demonstrated efficacy in severe OAK. Ampion's mechanism of action targets multiple pathways responsible for elevated cytokines to provide a therapeutic effect. Multiple human in vitro models have demonstrated the anti-inflammatory action of Ampion, reducing CXCL10 by up to
