Arch Therapeutics, Inc.

Additional data covered a variety of specialties, including vascular surgery, plastic surgery, general surgery, and podiatry, to further support clinical efficacy of AC5® Advanced Wound System in acute, chronic, and challenging wounds.

FRAMINGHAM, Mass., April 13, 2022 (GLOBE NEWSWIRE) -- Arch Therapeutics, Inc. (OTCQB: ARTH) (“Arch” or the “Company”), a marketer and developer of novel self-assembling wound care and biosurgical devices, today announced that two clinical case reports on the use of AC5^® Advanced Wound System (“AC5”) were presented as Poster Presentations and three additional cases were presented during a live Open Air Studio session at the 2022 Symposium on Advanced Wound Care (SAWC) Spring. The Open Air Studio video, featuring Terry Treadwell, MD, FACS, and Brock Liden, DPM, will be shared as it becomes available from SAWC.

Terrence W. Norchi, MD, President and CEO of Arch, said, “The data continues to support that the observed clinical benefits provided by AC5^® Advanced Wound System may be a game-changer for interventional wound care, which includes acute, chronic, and challenging wounds.”

The clinical case reports examined the use of AC5^® Advanced Wound System in patients with challenging wounds:

A New Treatment Modality to Expedite Healing in the Case of a Transmetatarsal Breakdown
Jean W. Gillon, MD – Vascular Surgeon, Sequoia Hospital
Poster Number: CS-004
Summary: This case report presents a patient with a history of several co-morbidities, a prior left below-the-knee amputation, and a recent right transmetatarsal amputation that was failing, resulting in extensive wet and dry gangrene. Due to the extensive infection, a right below-the- knee amputation was recommended. A second opinion was sought, and the surgeon's treatment strategy included weekly debridement and application of AC5^®. After three weekly applications of AC5^®, the wound bed was filled with healthy pink granulation tissue. This strategy played a crucial role in saving the limb and avoiding further amputation. Treatment of other patients using AC5^® Advanced Wound System may provide better understanding and outcomes for diverse wounds prone to failure and breakdown.

Optimizing the Wound Bed for Application of a Skin Graft with a Novel Adaptive Self-Assembling Peptide Barrier Scaffold and Peptide Technology
Thomas A. Davenport, MD – Plastic Surgeon, Long Island Plastic Surgical Group, PC
Poster Number: CS-109
Summary: This series presents two cases using AC5^® to optimize the wound bed prior to skin grafting. The first case was a traumatic wound on which a prior skin graft had failed, resulting in bone and tendon exposure. The second case was a post Mohs surgery resulting with a contour defect. Both cases required the wound bed to be filled with healthy tissue prior to closure with a skin graft. One application of AC5^® was used to prepare and optimize the wound beds for skin graft, resulting in complete closure of the wounds. Using AC5^® Advanced Wound System in wound bed preparation ahead of a graft with other patients may provide better understanding and outcomes for skin graft success.
