Filing Alert: Arch Therapeutics Chapter 11
Arch Therapeutics Files Chapter 11 in District of Massachusetts
Arch Therapeutics, Inc. and its debtor affiliate⁽¹⁾, a Framingham, MA-based biotechnology company developing self‑assembling peptide-based wound care products, filed for Chapter 11 protection on Apr. 18 in the U.S. Bankruptcy Court for the District of Massachusetts.
The filing follows significant challenges in accessing capital markets, including multiple unsuccessful attempts to uplist from the OTC markets to a national exchange – a requirement tied to burdensome convertible note covenants. According to court filings, these difficulties, compounded by high legal costs associated with financing efforts and regulatory filings (approximately $1.6 million over 18 months), hampered the commercialization of its lead product, AC5.
As liquidity tightened and noteholders became reluctant to provide further funding under workable terms, the company was left unable to meet obligations, including payroll, leading to the Chapter 11 filing. Arch now aims to secure DIP financing to fund a Chapter 11 sale process designed to maximize the value of its integrated assets, including intellectual property, regulatory clearances, and inventory.
The company reports $1 million to $10 million in assets and $10 million to $50 million in liabilities. The filing indicates that there will be funds available for distribution to unsecured creditors. The case number is 25-40409.
