Over the next six to eight weeks Dalton will be completing the quality control process which will culminate with the release of a first-ever, stand-alone cilastatin drug product to be used in a Phase II trial targeting drug toxin related AKI in hospitalized patients. Arch has agreed to be an industry partner with a group of Canadian clinical researchers in a planned Phase II clinical trial targeting drug toxin-related AKI, which is expected to start in late 2024. The Company will be acting as a study partner for grant funding opportunities, providing cilastatin drug product and providing scientific and regulatory advice. Arch has method of use patents in several jurisdictions including North America and Europe for repurposing cilastatin as a treatment for AKI. The patents are proprietary and/or exclusively licensed to Arch. Today’s announcement marks the completion of an important milestone in the Company’s plans to repurpose cilastatin as a new treatment to prevent toxin related AKI. Cilastatin has a slightly different mechanism of action compared with Arch’s novel drug candidate, LSALT peptide (Metablok) a non-enzymatic DPEP1 inhibitor. Whereas LSALT peptide specifically blocks DPEP1-mediated inflammation in the kidney, lungs and liver, cilastatin also has off target-effects that prevent toxin uptake in the kidneys. Thus, cilastatin is particularly effective for toxin-related AKI, but not suitable for other forms of non-toxin related AKI targeted by LSALT peptide. AKI reflects a broad spectrum of clinical presentations ranging from mild injury to severe injury that may result in permanent and complete loss of renal function. Clinically, the causes of AKI include sepsis, ischemia-reperfusion injury, and various endogenous as well as exogenous (drug) toxins. There is no specific therapeutic treatment available in the market today that prevents AKI. In the worst cases, the kidneys fail, requiring kidney dialysis or kidney transplant for survival. Exogenous toxins include a wide range of pharmaceutical drugs such as antibiotics (vancomycin, aminoglycosides), chemotherapeutic agents and radiographic contrast. Drug toxin-induced AKI represent approximately 30% of all AKI in hospitalized patients. As stated above, cilastatin is particularly suited to preventing AKI caused by drug toxins due to a unique off-target effect that blocks their uptake into the kidney tissue. Several in vitro and in vivo studies indicate that cilastatin prevents AKI induced by multiple nephrotoxic drugs (exogenous toxins).
