New therapeutic approach to facilitate healing of bed sores
Researchers from UBC and Vancouver Coastal Health are developing natural plant compounds into a healing gel that could speed up recovery and prevent wounds from returning
VANCOUVER, British Columbia, Nov. 17, 2025 (GLOBE NEWSWIRE) -- Every day in hospitals and long-term care homes, people with limited mobility develop painful pressure injuries, commonly known as bed sores. These wounds heal slowly and often reoccur in the same spot. Researchers from the University of British Columbia (UBC) and Vancouver Coastal Health are now creating a topical, plant-based gel that could help these chronic wounds heal faster with improved strength to prevent recurrence.
Led by Dr. David Granville (Professor, UBC Faculty of Medicine) and Heather Mak (Executive Director, Vancouver Coastal Health), the project is funded through Genome British Columbia’s (Genome BC) Genesolve program with support from viDA Therapeutics Inc. The team is working to develop natural compounds already approved by Health Canada into a clinically ready treatment that could move more quickly from the lab to the bedside.
Tackling a Growing Health Challenge
“Non-healing wounds are a silent epidemic,” said Dr. Granville. “Patients may suffer for many months with sores that never fully heal. And if they do heal, the healed wound is usually much weaker leaving it prone to tearing or further injury. By using safe, plant-derived compounds that block the enzyme responsible for this damage, we hope to restore the skin’s ability to repair itself and help people heal permanently.”
Pressure injuries are among the most common wounds encountered in healthcare. They develop when prolonged pressure on the skin, such as lying or sitting in one position for too long, disrupts blood flow and damages tissue. The resulting ulcers can result in significant pain, infection and a loss of independence, especially among older adults and those with limited mobility. British Columbia’s aging population means these injuries are becoming an even greater challenge for hospitals and care homes.
The Science Behind the Solution
Dr. Granville’s lab found that a protein called Granzyme B, an enzyme that cuts other proteins like scissors, accumulates in aging skin and slow-healing wounds. As its levels rise, the enzyme eats away at key structural proteins in the skin and hinders healing. By blocking Granzyme B with natural, plant-based compounds, the researchers believe that wounds will heal quicker and more completely, lowering the risk of reopening.
The team will test three Health Canada-approved compounds in topical gels using a standard model of pressure injury. Their results will form the basis for clinical trials and future healthcare use.
“Chronic wounds take a huge toll on patients, caregivers and the healthcare system,” said Dr. Heather Mak, Executive Director, Professional Practice and Education, Nursing, Vancouver Coastal Health. “By combining clinical insight with discovery research, we’re moving toward practical solutions that can improve recovery and quality of life.”
A Made-in-BC Collaboration
The project combines academic research, clinical expertise and biotech innovation. ViDA Therapeutics, a Vancouver-based company co-founded by Dr. Granville and Alistair Duncan, brings its experience developing granzyme inhibitors for age related and inflammatory conditions. The partners aim to translate these findings into a scalable, manufacturable gel that could be ready for clinician-sponsored trials as early as 2027.
“This project embodies what our Genesolve program was created to do: turn cutting edge discoveries into tangible health benefits,” said Dr. Federica Di Palma, Chief Scientific Officer and Vice President, Research and Innovation at Genome BC. “In this case, delivering real benefits to the healthcare system and patients."
