AM-Pharma, an Inventages portfolio company, raises €116m to conduct a pivotal Phase III Trial of recAP in Acute Kidney Injury

  • Proceeds to be used for the 1,400-patient international pivotal Phase III trial of recombinant human Alkaline Phosphatase (recAP) in patients with sepsis-associated acute kidney injury (SA-AKI)
  • AKI is a devastating disease, with a high mortality rate and no approved pharmacological treatments

 

Bunnik, The Netherlands, – AM-Pharma B.V. (‘AM-Pharma, the Company’), a clinical stage biopharmaceutical company, leading in the development of a treatment for acute kidney injury (AKI) with its innovative recombinant human Alkaline Phosphatase therapeutic (recAP) today announces that it has raised €116m [$133m] from a European syndicate of new and existing investors. These new funds will be used to carry out a multi-national pivotal Phase III trial of recAP in 1,400 patients with sepsis-associated acute kidney injury (SA-AKI). Last year AM-Pharma reported promising results from its STOP-AKI Phase II clinical trial, which demonstrated significant improvements in survival and kidney function.

AKI is a devastating disease, with a high mortality rate and no approved pharmacological treatments. The most important cause of AKI, which affects millions of patients worldwide, is sepsis. 1,2 AM-Pharma was awarded Fast Track designation by the US Food and Drug Administration in 2016 and recAP has the potential to be a first-in-class medicine for AKI.

The results of AM-Pharma’s adaptive Phase II STOP-AKI study of recAP in 301 sepsis patients with AKI, demonstrated a significant relative reduction in mortality of more than 40% in the treatment group compared to the placebo group. Whilst the primary endpoint – short term kidney function – was missed, long-term kidney function was significantly improved. Throughout the study, recAP was shown to be safe and well tolerated. These results were published in the Journal of the American Medical Association (JAMA).3

This new capital will be used to support the largest ever clinical trial in SA-AKI, seeking to enroll up to 1,400 patients with SA-AKI at multiple sites in approximately 12 countries. Following recent discussions with regulatory authorities in the US and Europe, AM-Pharma plans to submit market authorization applications following the successful completion of this upcoming single pivotal Phase III study.

About Acute Kidney Injury (AKI)

Acute Kidney Injury (AKI) involves inflammatory processes in the kidney which can lead to complete loss of renal function. Hospital‐acquired AKI affects annually around 3 million patients in Europe, the US and Japan, and is associated with mortality in roughly 700,000 patients. It occurs in 40-60% of critical care admissions. Depending on the severity and cause of renal injury, mortality ranges from 10% to as high as 60%. In the US alone, hospitals spend around $10 billion each year on managing this major medical problem. The most important causes of AKI are sepsis, cardiovascular surgery, exposure to nephrotoxic drugs and trauma. Currently the only treatment options are dialysis and supportive care. No drugs are approved to treat this condition. Typically, these patients are treated in Intensive Care Units, often with support of nephrologists.1,2,3,4

AKI – recAP Mechanism of Action

Acute Kidney Injury (AKI) is a severe inflammation and damage of the kidney resulting in a sudden drop in kidney function, which can sometimes result in complete kidney failure. AM-Pharma has discovered that one key function of the enzyme Alkaline Phosphatase (AP) is to protect organs against inflammation and tissue damage.

AP acts as a detoxifying agent by removing phosphate from extracellular substrates. The dephosphorylation of pro-inflammatory substances like lipopolysaccharides (LPS) and extracellular ATP plays an important anti-inflammatory role. Research has shown that ATP dephosphorylation has a double effect in protecting against kidney injury. When the pro-inflammatory ATP is dephosphorylated the resulting adenosine further reduces inflammation through the activation of the immunosuppressive adenosine A2a receptor pathway (A2aR).


About recAP

AM-Pharma’s therapeutic candidate, recAP (recombinant Alkaline Phosphatase), is a proprietary recombinant human AP constructed from two naturally occurring human isoforms of the AP enzyme. recAP is highly stable and active and has a dual mechanism of action via dephosphorylation of lipopolysaccharides (LPS) and extracellular ATP. AM-Pharma has shown that treatment of patients with exogenous AP not only reduces local and systemic inflammation but also protects the kidney against further damage.

Awarded fast track designation by the US Food and Drug Administration in 2016, recAP has the potential to be a first-in-class medicine. The results of an adaptive Phase II STOP-AKI study of recAP in 301 sepsis patients with AKI were published in 2018 in the prestigious Journal of the American Medical Association (JAMA). recAP demonstrated a significant relative reduction in mortality of more than 40% in the treatment group compared to the placebo group without any safety observations of concern. AM-Pharma is now preparing for the pivotal Phase III study of recAP in patients with sepsis associated kidney injury.
