LSALT Peptide (Metablok), is the company’s lead drug candidate targeting organ inflammation in the lungs, liver and kidneys.
LSALT peptide trials and development

In 2023, the company produced new human safety and efficacy data in a Phase I dose escalation study and announced that it has received FDA permission to proceed with a new Phase II human trial targeting organ inflammation in other applications such as cardiac surgery-associated kidney injury (CS-AKI).

Previous Phase II and III trials during the pandemic accelerated Arch’s drug development plans and shortened the path toward the approval and commercialization of LSALT peptide. Inflammation in the lungs was a common complication of hospitalized pandemic patients and LSALT peptide was used for the first time in a Phase II trial to treat acute lung inflammation in that setting. Successful results accelerated LSALT peptide’s inclusion in a national Phase III trial in Canada looking for new treatments to treat acute lung inflammation in the later stages of the pandemic.
