Introducing Amferia wound dressing for animal care — binds and kills bacteria without harming the body

How antimicrobial hydrogel can revolutionize clinical treatments

Binds and kills 99.99% of bacteria without harming the body – even resistant bacteria

Introducing Amferia wound dressing for animal care — binds and kills bacteria without harming the body

Antimicrobial dressing:

Amferia has invented a new antimicrobial hydrogel that targets, binds, and rapidly kills up to 99.99% of bacteria upon contact. The hydrogel consists of amphiphilic antibacterial polymers mimicking the immune system. Because the hydrogel binds those polymers in place, nothing is released into the wound, making the dressing safe for the body. 

Amferia is producing an antimicrobial hydrogel wound dressing for animal care, that has successfully undergone clinical testing in multiple countries across Europe. For more information about our products and availability, contact us now.

Appropriate for acute and low exuding wounds—such as post-surgical incisions—this product can be used as a wound contacting hydrogel pad supported on the wound by a secondary dressing.

Meant exclusively for veterinary in-clinic use, in places such as surgical care units or in-patient care, all products are supplied sterile and will include instructions for use.

Evidence of safety and efficacy in post-surgical wounds

Clinical case reports:

Amferia has collaborated with five leading veterinary clinics across Europe and obtained over 100 case reports on a variety of post-surgical wounds of cats and dogs.

In each case, Amferia’s hydrogel dressing enabled safe healing of wounds with no complications. Furthermore, the product could be adapted easily to the complex contours of the animals' bodies and adjusted to the required sizes.

The surgeons who used the dressings have provided excellent feedback on the usability, safety and existing evidence of antimicrobial efficacy.

Infected wounds — killing multi-resistant bacteria

Chronic wounds:

Clinical case reports involving Amferia hydrogel dressings have been performed on infected chronic wounds in collaboration with two clinics in Germany and the Netherlands.

Together with Amferia, the clinics have performed five case evaluations of the Amferia hydrogel dressing in hard-to-heal infected wounds of one dog and four cats, all colonized with multi-resistant pseudomonas aeuruginosa or MRSA bacteria. 

All wounds were open wounds from either trauma or chronic complications, and the patients suffered from recurring wound complications over a period of two to three months. The attending wound specialist requested Amferia dressing for trials on the patients and noted a clear effect within 24 hours, noting bio-burden reduction and formulation of new granulation tissue.

100 times reduction of bacterial load in deep infected wounds

In-vivo study:

Amferia collaborated on an in-vivo infection model study with Chalmers University and the Department of Biomaterials at Sahlgrenska University. 

The study results, published in ACS Biomaterials Science, describe a wound model in mice heavily infected with bacteria. The results demonstrated 100 times reduction of bacterial load in the wounds treated with the amphiphilic antimicrobial hydrogel.  

This is especially impressive, given that the wound was deep and the bacterial load was extremely high. The results demonstrated the strong effect the hydrogel had on bacterial removal, from the wound in a statistically significant manner, without releasing any substances into the body.

Amferia’s first human clinical study published

June 26, 2023

We are thrilled to share that our dedicated team at Amferia in collaboration with Chalmers tekniska högskola has published a randomised controlled study in the Journal of Wound Care that demonstrates the outstanding antibacterial performance of our hydrogel wound dressing.  We studied our wound dressing on intact human skin as a model to evaluate the speed and efficacy of the dressing to kill bacteria — and the results were truly remarkable!

By utilizing the Amferia Antimicrobial Hydrogel technology, we eradicated bacteria when placed in contact with skin within a short period of three hours.

By utilizing the Amferia Antimicrobial Hydrogel,   bacteria was eradicated within three hours.

These findings demonstrate the potential of our antibacterial wound dressing to significantly reduce the risk of infection in wounds, offering new possibilities for improved patient outcomes. This study lays the foundation for our future clinical studies in human wounds.

Amferia raises SEK 15.4 million to launch innovative antimicrobial wound care dressing

January 27, 2023

The financing was raised from Almi Invest, Chalmers Ventures, and with several angel investors to support launch of Amferia’s first product, a wound care dressing with a patented hydrogel that actively combats infections and kills antibiotic-resistant bacteria.

Amferia's innovative, anti-microbial solution can be used on wide-ranging wounds from simple skin injuries, post-operative wounds to chronic wounds and trauma / burn wounds. The WHO predicts that antibiotic-resistant infections, including those from wounds could become one of the leading causes of both illness and death over the next ten years.

“I am grateful to all our committed investors: Every year, nearly 1 million people die globally because of infections caused by antibiotic-resistant bacteria and at least a quarter of those infections begin with a simple wound on the skin. Amferia's wound care solution is a game-changer and will save lives. The resistance problem is even more challenging within the animal health sector.”, says Agneta Edberg, Chairperson of Amferia.

Amferia's wound care solution is a game-changer and will save lives.

Amferia's patented material, an antimicrobial amphiphilic hydrogel, has been developed through several years of research in collaboration with Chalmers University of Technology and contains molecules inspired by body’s own immune system. The material instantly kills all bacteria (even antibiotic resistant) by binding to and disrupting their cell membranes, all without damaging the body’s own cells or entering the bloodstream. The first product from this technology is a hydrogel wound-care dressing for dry-to-low exuding wounds, while the material is also being investigated for development in several other areas, including sprays for deep wounds, and coatings for implants and a variety of catheters. In September of 2022, Amferia launched its first wound dressings for animal health in Sweden and plan on expanding across Europe during 2023. In parallel, the company is preparing to file for regulatory clearance in the US for human health.

The wound care market currently generates sales for over US $ 2 billion globally with a projected CAGR of 5 %. However, existing alternatives on the market often contain antibiotics that carry the risk of causing resistance or antiseptics that may harm body cells and negative environmental impact.

We already have our first product on the market for animal wound care in Sweden

“The investment enables us to perform three key tasks: scale up and launch our products for animal health in Europe, file for FDA clearance of the application for human health and thirdly initiate more clinical studies in both market segments. This ambition is supported by the fact that we already have our first product on the market for animal wound care in Sweden”, says Anand Kumar Rajasekharan, CEO of Amferia.

Pre-clinical research on new antimicrobial spray and coating technology published

January 26, 2023

Amferia announced today that it has, in collaboration with Chalmers University of Technology, published two important scientific articles in peer-reviewed journals that describe the pre-clinical studies of its platform technology, Amphiphilic Antimicrobial Hydrogel as sprays and coatings for various medical device applications.

Amferia’s platform technology is an amphiphilic antimicrobial hydrogel material that can rapidly bind and kill all types of bacteria, even resistant bacteria, without harming the body. In an effort to enable further applications of this material, Amferia collaborated with Chalmers University of Technology to test and develop the patented technology as sprayable formulation and as coatings fight off bacterial infections in medical devices.

Today, the extensive pre-clinical data from this research has been published in two scientific articles in peer-reviewed journals*. The research was built on the formulation of the Amphiphlic Antimicrobial Hydrogel as small discrete particles, which were then further developed as sprayable form for wound care and as a coating on existing materials like silicone catheters. The results from these studies show powerful antimicrobial effect, safety to human cells while being stable in biological environments such as serum.

The material has been shown to be effective against many different types of bacteria, including those that are resistant to antibiotics

Martin Andersson, Professor at Chalmers University and Co-founder of Amferia − “Our innovation can have a dual impact in the fight against antibiotic resistance. The material has been shown to be effective against many different types of bacteria, including those that are resistant to antibiotics, such as Methicillin-resistant Staphylococcus aureus (MRSA), while also having the potential to prevent infections and thus reduce the need for antibiotics,.”

The research was undertaken based on the strong potential of Amferia’s technology, but also based on a clear need from the human and animal health care system on fighting infections in the context of deep infected wounds as well as for various medical devices such as urinary catheters. Amferia and Chalmers will continue to collaborate on this research and are planning to further study the use of the new formulations in clinical settings, both for human and animal care.

We are seeing the great potential of our technology going beyond wound care into the realm of broader medical devices

Anand Rajasekharan,CEO of Amferia − “This is an important achievement for Amferia as we are seeing the great potential of our technology going beyond wound care into the realm of broader medical devices such as coatings and sprayable systems. Our current product is a wound dressing and we look forward to follow-up the same with these pipeline products that will have a stronger impact for addressing antibiotic resistance.”
