Arch Biopartners’ Cilastatin Drug Candidate to Participate in the PONTIAC Phase II Trial Targeting Acute Kidney Injury Caused by Drug Toxins
Arch Biopartners Inc. (TSX Venture: ARCH, OTCQB: ACHFF) announced that its drug candidate cilastatin will participate in the PONTIAC Phase II trial, targeting acute kidney injury (AKI) caused by drug toxins. The 900-patient trial, funded by $1.9 million in grants, will evaluate cilastatin's efficacy in preventing AKI from antibiotics, chemotherapeutics, and radiographic contrast. Arch is repurposing cilastatin, a dipeptidase-1 inhibitor, as an AKI treatment, leveraging its unique ability to block toxin uptake in kidney tissue. This trial complements Arch's ongoing Phase II study of LSALT peptide for cardiac surgery-associated AKI. Together, these trials target about 50% of hospital AKI cases, for which no treatment currently exists.
Arch Biopartners Inc. (TSX Venture: ARCH, OTCQB: ACHFF) ha annunciato che il suo candidato farmaceutico cilastatina parteciperà alla sperimentazione clinica di Fase II PONTIAC, mirata a combattere l'insufficienza renale acuta (AKI) causata da tossine farmacologiche. Lo studio, che coinvolgerà 900 pazienti e sarà finanziato con 1,9 milioni di dollari in sovvenzioni, valuterà l'efficacia della cilastatina nel prevenire l'AKI derivante da antibiotici, chemioterapici e mezzo di contrasto radiografico. Arch sta riproponendo l'uso della cilastatina, un inibitore della dipeptidasi-1, come trattamento per l'AKI, sfruttando la sua abilità unica di bloccare l'assorbimento delle tossine nei tessuti renali. Questo studio si aggiunge alla ricerca in corso di Arch sulla peptidasi LSALT per l'AKI associato alla chirurgia cardiaca. Insieme, questi studi mirano a trattare circa il 50% dei casi di AKI in ospedale, per i quali attualmente non esiste alcun trattamento.

El ensayo de 900 pacientes, financiado con 1,9 millones de dólares en subvenciones, evaluará la eficacia de la cilastatina en la prevención de AKI causado por antibióticos, quimioterapéuticos y contraste radiográfico. Arch está reutilizando la cilastatina, un inhibidor de dipeptidasa-1, como tratamiento para el AKI, aprovechando su capacidad única para bloquear la absorción de toxinas en el tejido renal. Este ensayo complementa el estudio en curso de Arch de péptido LSALT para AKI asociado a cirugía cardíaca. Juntos, estos ensayos apuntan a tratar alrededor del 50% de los casos de AKI en hospitales, para los cuales actualmente no existe tratamiento.

TORONTO, Aug. 02, 2024 (GLOBE NEWSWIRE) -- Arch Biopartners Inc., (“Arch” or the “Company”) (TSX Venture: ARCH and OTCQB: ACHFF), announced today that cilastatin, the Company’s second drug candidate for preventing acute kidney injury (AKI), will participate in the upcoming investigator led trial entitled “Prevention Of NephroToxin Induced Acute kidney injury with Cilastatin” (PONTIAC). PONTIAC is a 900 patient Phase II trial that will evaluate the efficacy of the dipeptidase-1 inhibitor cilastatin for preventing AKI caused by drugs such as antibiotics, chemotherapeutic agents and radiographic contrast.
The PONTIAC clinical team of investigators, based out of the Universities of Calgary and Alberta, was awarded
The PONTIAC clinical team sponsoring the trial is based in Calgary and is currently preparing to submit a Clinical Trial Application (CTA) to Health Canada to proceed with the trial by the fourth quarter of 2024. Arch is acting as a study partner for grant funding opportunities, providing cilastatin drug product and providing scientific and regulatory advice.
Cilastatin is an enzymatic dipeptidase-1 (DPEP1) inhibitor approved by the FDA in 1985 for use as fixed combination with imipenem to treat different types of bacterial infections. Arch has method-of-use patents for repurposing cilastatin as a treatment for acute kidney injury (AKI) in several jurisdictions, including North America and Europe. There is no commercial history of cilastatin as a stand-alone drug product.
The drug 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 has off target-effects that prevent toxin uptake in the kidneys. As such, cilastatin is particularly effective for toxin-related AKI.
The PONTIAC trial builds on research published by lead Arch scientists and their colleagues in JCI (The Journal of Clinical Investigation) in 2018, when cilastatin was shown in pre-clinical models to effectively inhibit leukocyte recruitment and drug toxin uptake in the kidney, thereby preventing AKI caused by radiographic contrast.
Today’s announcement provides Arch’s drug development program with a second target indication to prevent acute injury to the kidneys. The Company is currently dosing patients with its lead drug candidate, LSALT peptide, in an ongoing, international Phase II study targeting cardiac surgery-associated AKI (CS-AKI).
Quote from Mr. Richard Muruve, CEO Arch Biopartners:
“We are excited to be the industry partner of the PONTIAC trial while we continue to sponsor the Phase II trial for LSALT peptide targeting CS-AKI. The PONTIAC and CS-AKI trials combined are targeting about half of all AKI cases occurring in hospitals today. We are very driven to complete these trials and improve global kidney care with the first ever therapeutics to prevent acute kidney injury.”
About 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 (drug) toxins. There is no specific therapeutic treatment available in the market today that prevents AKI. In the worst cases, the kidneys fail, requiring dialysis or kidney transplantation for patient survival.

About Cilastatin
Cilastatin was originally developed in the early 1980s by Merck Sharp & Dohme Research Laboratories to limit DPEP1’s role in the breakdown of imipenem, a β-lactam antibiotic used for the treatment of systemic infections. Cilastatin was approved for use as fixed combination with imipenem to treat different types of bacterial infections. This fixed combination, approved by the FDA in 1985, is currently marketed under different names, including Primaxin® (USA, UK, Australia, Italy), Tienam® (Spain, Belgium) or Zienam® (Germany). Patents for imipenem and cilastatin have expired and the combination drug is currently in a generic phase. There is no commercial history of cilastatin as a stand-alone drug product.
