Safety and Efficacy Study of VM202 in the Treatment of Chronic Non-Healing Foot Ulcers. This study will assess the safety and efficacy of using gene therapy via intramuscular injections of the calf for patients with chronic non-healing foot ulcers.
The first patient has been dosed in a Phase III trial assessing ViroMed’s VM202, the first pivotal study of a gene therapy indicated for patients with nonhealing diabetic foot ulcers (NHU) and concomitant peripheral artery disease (PAD).
The Phase III trial (NCT02563522) is a double-blind, placebo-controlled, multicenter study designed to evaluate VM202 for safety and efficacy in 300 adults with a diabetic foot ulcer and concomitant PAD. Two hundred patients will be randomized to VM202 and the other 100 to placebo, ViroMed’s U.S. division VM BioPharma said yesterday. (more…)
Scars are a particularly sore subject for most people. Not only are they aesthetically unpleasing, but some of them can prove painful. That’s why research into minimizing the appearance of scars continues to be a central priority of wound care-related research. In the last several months alone, there have been quite a few exciting such breakthroughs. (more…)
Scientists at Ohio State University have developed a new method that has the capability of changing the body’s existing cells into new cells to promote healing. The method, called Tissue Nanotransfection (TNT), reprograms cells through a device that uses nanotechnology. The way it would work: First, doctors would apply a light electrical stimulation to the surface of the skin. They would then place a small chip about the size of a cuff link onto the site of the wound. In less than a second, this chip would deliver reprogramming factors (pre-programmed DNA or RNA) non-invasively into living skin cells via a high-intensity, focused electric field, converting them into whatever type of cells a scientist or doctor may choose.

Washington, D.C. — In a presentation to the American Chemical Society meeting, Ankit Agarwal, a postdoctoral researcher at the University of Wisconsin-Madison, described an experimental approach to wound healing that could take advantage of silver’s anti-bacterial properties, while sidestepping the damage silver can cause to cells needed for healing.
Silver is widely used to prevent bacterial contamination in wound dressings, says Agarwal, “but these dressings deliver a very large load of silver, and that can kill a lot of cells in the wound.” (more…)
A new study has identified a peptide, derived from the Komodo dragon, called VK25, which can be synthesized and used as an antimicrobial peptide to promote wound healing.
The new research has identified (see below) a peptide found from the Komodo dragon (Varanus komodoensis), called VK25, which appears to be useful as a cationic antimicrobial peptide (CAMP). There is currently considerable interest in antimicrobial peptides in a world where antibiotic effectiveness is in decline. These peptides are potent, broad spectrum antibiotics which demonstrate potential as novel therapeutic agents. (more…)
Pennsylvania state trooper Matt Uram was talking with his wife at a July Fourth party in 2009 when a misjudged spray of gasoline burst through a nearby bonfire and set him alight. Flames covered the entire right side of his body, and after he fell to the ground to smother them, his wife beat his head with her bare hands to put out his burning hair. It was only on the way to the ER, as the shock and adrenaline began to wear off, that the pain set in. “It was intense,” he says. “If you can imagine what pins and needles feel like, then replace those needles with matches.” (more…)
An innovative “Smart Scar-Care” pad which serves the dual functions of reinforcing pressure and occlusion has been designed by researchers to treat hypertrophic scars from burns, surgeries and trauma.
Compared with the traditional pressure pads and silicone gel sheets, “Smart Scar-Care” pad has the advantages of both.
It showed good performance in reducing pigmentation and vascularity, improving elasticity and preventing dehydration in a clinical trial. It is more durable and user-friendly compared with the traditional pad (polyethylene foam) as reported by the patients. This innovative design has won the Grand Award and Gold Medal with the Congratulations of Jury at the 45th International Exhibition of Inventions of Geneva, 2017. (more…)
MicroRNAs are interesting target structures for new therapeutic agents. They can be blocked through synthetic antimiRs. However, to date it was not possible to use these only locally. Researchers at Goethe University Frankfurt have now successfully achieved this in the treatment of impaired wound healing with the help of light-inducible antimiRs.
MicroRNAs are small gene fragments which bond onto target structures in cells and in this way prevent certain proteins from forming. As they play a key role in the occurrence and manifestation of various diseases, researchers have developed what are known as antimiRs, which block microRNA function. The disadvantage of this approach is, however, that the blockade can lead to side effects throughout the entire body since microRNAs can perform different functions in various organs. Researchers at Goethe University Frankfurt have now solved this problem. (more…)
A substance found in parasitic worms’ spit might help prevent thousands of amputations a year, scientists in north Queensland have said. James Cook University researchers in Cairns are harnessing the molecule produced by a Thai liver parasite that can “supercharge” the healing of wounds.
Australian Institute of Tropical Health and Medicine parasitologist Michael Smout said non-healing wounds were of particular concern for diabetics and smokers. Dr Smout said the parasite used the molecule to keep its host healthy and prolong its own life. “It’ll live for a decade or two, and it’s munching around your liver, and zipping up the wounds as it goes,” he said.

It’s necessary for the skin to heal the wounds after getting injured. For the first time, scientists discovered that the changing stem cell dynamics contribute to wound healing. The main purpose of these studies was to understand how stem cells differentiate, migrate, and proliferate to repair the tissue damage after trauma.
A team from Université libre de Bruxelles (ULB) started their research on stem cells. Professor of ULB, Dr. Cédric Blanpain MD/Ph.D, WELBIO investigator and the lead researcher of this study, defined the cellular and molecular mechanisms that play active roles in wound healing. The research report was first published in the Journal of Nature Communications.
The skin of a creature is just like an outer shield which protects the inner tissues and other organs from outer injuries. If somehow the outer shield gets disrupted then body activates a cascade of cellular and molecular event to repair the damage and restore skin integrity. ScienceDaily reported that minor defects in these events lead to improper repair causing acute and chronic wound disorders.
In the new study, scientists revealed that distinct stem cells populations contribute in healing the wound. Although it is not cleared yet how proliferation, differentiation, and migration get balanced by stem cell populations during the healing process. Co-author of this study Dr.Sophie Dekoninck said in a statement,“The molecular characterization of the migrating leading edge suggests that these cells are protecting the stem cells from the infection and mechanical stress allowing a harmonious healing process”.
Each team has taken a different approach or tackled a unique situation or medical ailment, and that ensures a more well-rounded coverage that helps a larger pool of patients. However, few scientists have a more grand scope than Ronke Olabisi, a professor of biomedical engineering at Rutgers University.
Reaching for the stars
As the university explained in a recent press release, Olabisi is hard at work on several projects aimed at improving wound healing both on earth and during manned space missions. During space travel, especially as astronauts spend months at a time in stations, the lack of gravity has a huge impact on the human body. Muscle and bones will actually start to deteriorate, and tissues will lose much of their elasticity. Olabisi’s main goal is to study in-depth why this occurs and how to fix, and she believes she can apply much of the same knowledge to wound care on Earth.
