Arch has the opportunity to sponsor a Phase II trial for cilastatin in toxin-related AKI targeting either nephrotoxic drug and/or rhabdomyolysis-associated AKI (explained further below).
The PIND meeting provided the Arch team with guidance from the FDA for the content of a future IND application for cilastatin. An IND application is a request to the FDA for authorization to administer a new drug to patients in a human trial. The Arch team received clarity on several items including cilastatin pharmacology; manufacturing of a cilastatin drug product; design of phase II study protocol targeting toxin-related AKI; and the regulatory path that would lead to a New Drug Application (NDA).
Arch is acting as an industry partner with clinical researchers in
Arch management is overseeing the development and manufacturing of a first-ever, stand-alone cilastatin drug product. Arch has arranged for the production of the first lot of a cilastatin to occur during the summer of 2024.
Arch has method of use patents in several jurisdictions for repurposing cilastatin as a treatment for AKI. The patents are either proprietary or exclusively licensed to Arch.
Quote from
“The PIND meeting was the first major milestone in the effort to commercialize cilastatin, Arch’s second drug targeting DPEP-1. Third-party research and clinical interest to test cilastatin as a first ever treatment for both rhabdomyolysis-associated AKI and drug toxin-related AKI have provided the catalyst for Arch to advance this technology toward an NDA in parallel with the LSALT peptide program. We look forward to working with our research and clinical collaborators to establish cilastatin and DPEP-1 inhibition as a new treatment to prevent toxin-related AKI.”
About Cilastatin
Cilastatin is an enzymatic dipeptidase-1 (DPEP-1) inhibitor originally developed in the early 80´s by
Cilastatin has a slightly different mechanism of action compared with Arch’s novel drug candidate, LSALT peptide (Metablok) a non-enzymatic DPEP-1 inhibitor. Whereas LSALT peptide specifically blocks DPEP-1-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 the LSALT peptide.
Cilastatin as a potential treatment for AKI
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 toxins.
Exogenous toxins include a wide range of pharmaceutical drugs such as antibiotics (vancomycin, aminoglycosides), chemotherapeutic agents and radiographic contrast. The incidence of AKI is approximately 30% of all hospitalized patients receiving nephrotoxic medications.
Endogenous toxins include heme-pigments such as myoglobin released during severe muscle injury (rhabdomyolysis) due to crush or blunt trauma, prolonged immobilization or drugs. Heme-pigments are avidly taken up by the kidney where they directly damage cells resulting in AKI. The kidney is particularly susceptible to heme-pigment induced injury with AKI occurring in up to 50% of patients experiencing rhabdomyolysis.
As stated above, cilastatin is particularly suited to preventing AKI caused by exogenous and endogenous 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 acute kidney injury (AKI) induced by multiple nephrotoxic drugs (exogenous toxins) and/or heme-pigments (endogenous toxins).
