Key preclinical data for HypoPet’s cat allergy vaccine (HypoCat™ / VC001) published in leading allergy journal.

Zürich Switzerland 17th of April 2019 – HypoPet AG today announced the publication of important preclinical data for their cat allergy vaccine, HypoCat™. The data were published online 17th of April 2019 in an article entitled “Immunization of cats to induce neutralizing antibodies against Fel d 1, the major feline allergen in human subjects. “in the Journal of Allergy and Clinical Immunology.

The published work, led by HypoPet’s Zurich-based research team (in collaboration with researchers from the Latvian Biomedical Research and Study Centre Riga, Vetsuisse Faculty University of Zurich and the Functional Genomics Centre Zürich, University of Zürich), showed that HypoPet’s virus-like particle vaccine targeting the major feline allergen (i.e. Fel d 1) to which humans are allergic, successfully induced Fel d 1 binding antibodies in cats and that these antibodies neutralized the allergen. Furthermore, the HypoCat™ vaccine was reported to be well tolerated without any overt toxicity. The data described in the paper were generated from 4 separate studies involving a total of 54 cats.

Dr Gary Jennings, CEO of HypoPet AG, commented, “We are very pleased to publish this data which shows our HypoCat™ vaccine is able to produce high levels of antibodies in cats and that these antibodies can bind and neutralize the Fel d 1 allergen produced by the animals. This work was a key step in the milestone driven development of HypoCat™, the lead project in our product pipeline. Moreover, our development partner Benchmark Holdings recently announced successful completion of other key safety and efficacy trials and transfer of the HypoCat manufacture process to GMP. Consequently, we are pressing ahead with registration studies and discussions with European and U.S regulators with the hope of bringing this much-needed product to the market”

About cat allergy and HypoCat

Allergy suffered by humans to companion animals such as cats and dogs and the lack of effective therapies for those who suffer these allergies is an area of significant unmet medical and veterinary need. Ten percent of the general human population suffers from cat allergy and ~ 25% of households have cats. Moreover, sensitization to cats is a strong risk factor for children to develop asthma. There is no effective treatment for cat allergy in humans; treatment of symptoms or avoidance of animals are the usually prescribed recourses. Separation of owners and families from their beloved pets is traumatic for both animal and human and in many cases can not even be contemplated. Nevertheless, allergy suffered by owners, friends & relatives is a leading cause of cat abandonment. Sadly, of the 3.4 million cats abandoned annually to U.S cat shelters, approximately 1.4 million of these animals are euthanized. Allergy is also a leading reason for abandonment of cats into urban and native environments. In addition to the suffering experienced by the abandoned animals, problems are created for native fauna through predation.

HypoPet's novel approach to this shared problem of pets and their owners is to intervene at the source by lowering the allergenicity of the pet itself. A "low" allergenic cat could enable the trauma of separation to be avoided and the negative health consequences of human allergy to be lessened. To achieve this goal HypoPet is leveraging its innovative virus-like particle vaccine technology as a means for safely reducing the allergenicity of pets. After vaccination the pet will produce allergen-specific antibodies which bind the target allergen and lower or neutralize its allergenic effect in humans. The veterinary and commercial potential of our concept was recognized when HypoPet became a winner of the Swiss Innovation Forum, Technology Award in November 2013 for its HypoCat™ vaccine and a recipient of a research grant from the Swiss Commision for Technology and Innovation in 2014.
HypoPet’s lead project HypoCat™, is a vaccine to lower the allergenicity experienced by humans towards cats. Fel d 1, a cat protein secreted into saliva and tears and found on the pelt, is the principle allergen to which cat allergy sufferers react. Indeed, more than 85% of cat allergic patients have potent allergy-inducing IgE antibodies against this protein. It is known that decreasing exposure of allergic humans to Fel d 1 has a significant benefit on symptoms and health. HypoPet’s innovative approach is to intervene “at the source“ i.e. lower allergenic Fel d 1 on the cat itself. To achieve this HypoPet is developing a vaccine, based upon its patented VLP paltform technology, to induce anti-Fel d 1 antibodies in the cat. HypoCat™, is a Fel d 1 virus-like particle conjugate vaccine that has been demonstrated to overcome the inherent immune-tolerance to self-molecules such as Fel d 1 and induce strong and lasting anti-Fel d 1 antibody responses in cats1, 2. These antibodies bind Fel d 1 and thus have the ability to lower or neutralize its allergenic effect in humans. The veterinary/medical and commercial potential of the HypoCat™ vaccine was recognized when HypoPet won the Swiss Technology Award in 2013. Subsequently, in 2014, HypoPet received a Grant from the Swiss Commision for Technology and Innovation to advance the HypoCat project. Development of HypoCat™ has been further advanced through a commercialization, manufacture, and distribution agreement entered into with Benchmark Holdings PLC in September 2014.

HypoPet scientists publish data showing proof-of-principle achieved for a vaccine targeting osteoarthritic pain

Zürich Switzerland 19th of March 2019 – HypoPet AG today announced the publication of proof of principle data for a vaccine with the potential to translate into a novel therapy for osteoarthritic pain in companion animals. The data were published online 12th of March 2019 in an article entitled “Active immunisation targeting nerve growth factor attenuates chronic pain behaviour in murine osteoarthritis” in the Annals of the Rheumatic Diseases

A research collaboration between Martin Bachmann’s research groups at the Jenner Institute University of Oxford and University of Bern and academic researchers from the Kennedy Institute of Rheumatology University of Oxford and Latvian Biomedical Research and Study Center demonstrated the succesfull development and testing of a VLP-based vaccine with the potential to treat chronic pain caused by osteoarthritis. The virus-like particle vaccine triggers the immune system to produce antibodies that block the activity of nerve growth factor – a key mediator of inflammatory and chronic pain.

Professor Martin Bachmann CSO of HypoPet AG commented, “I am happy to see the vaccine platform perform so well, and look forward to seeing the vaccine enter clinical testing in companion animals in the near future”.

The Annals of the Rheumatic Diseases (ARD) is an international peer review journal committed to promoting the highest standards of scientific exchange and education. It covers all aspects of rheumatology, which includes the spectrum of musculoskeletal conditions, arthritic disease, and connective tissue disorders.

About pain and osteoarthritis
Effective and safe treatment of chronic pain associated with degenerative joint disease and cancer in companion animals is a major unmet need in veterinary medicine. The incidence of such diseases is increasing as companion animals age and live longer. As an example, mostly dogs but also cats and horses are affected by degenerative joint diseases. About 20% of dogs will develop osteoarthritis. The mainstays of current treatment are non-steroidal anti-inflammatory drugs, however, they are not sufficiently effective, have side effects and suffer convenience and compliance issues. Therefore, the need for new treatment options is significant. Experimental and clinical studies have identified a number of key molecules that mediate inflammatory and neuropathic pain and cancer pain. One of these molecules, nerve growth factor (NGF), is an ideal target for controlling pain using antibody based therapies. Indeed, in humans, dogs and cats, efficacy and safety have been demonstrated in with monoclonal antibodies that target NGF or its receptor.

Proof of concept data for HypoPet’s virus-like particle vaccine for treating canine atopic dermatitis published in leading allergy journal.

Zürich Switzerland 11th of April 2018 – HypoPet AG today announced the publication of Proof of Concept data for a vaccine for treating canine atopic dermatitis (CAD) in the renowned Journal of Allergy and Clinical Immunology. The data were published online 4th of April 2018 in an article entitled “Vaccination against IL-31 for the treatment of atopic dermatitis in dogs”. Furthermore, the paper on canine atopic dermatitis is published “back to back” with a manuscript entitled “Treating insect bite hypersensitivity in horses with active vaccination against IL-5”. The vaccine described in this second work utilizes the same platform technology as that used by HypoPet.
Dr Gary T. Jennings CEO of HypoPet AG commented, “The encouraging result we achieved with the CAD vaccine (VC002) in a dog model of atopic dermatitis is a significant development milestone and suggests VC002 has the potential to make an important contribution to the treatment of this devastating condition. The tandem publications also show that our therapeutic virus-like particle vaccine platform is able to induce clinically effective levels of neutralizing antibodies against different targets and in different species. This ably demonstrates the potential of our technology to be developed in to effective veterinary medicines.”
The Journal of Allergy and Clinical Immunology publishes high-impact, cutting-edge clinical and translational research papers for allergists, immunologists, dermatologists, gastroenterologists, and other physicians and researchers interested in allergic diseases and clinical. The JACI is the most-cited journal in the field of allergy and clinical immunology.

About the CAD vaccine (VC002)
VC002 is a therapeutic vaccine in development for the treatment of canine atopic dermatitis (CAD). The product candidate VC002 represents a unique and novel approach to the treatment of CAD. Interleukin 31 is a key itch-inducing cytokine produced by immune cells in the skin during the allergic reaction in atopic dogs. The pruritic action of IL-31 can be neutralized with antibodies thereby providing marked clinical benefits to dogs suffering from CAD. VC002 is a virus-like particle nanoparticle vaccine designed to induce anti-IL31 antibodies when administered to dogs. In November 2015, Animal health company Benchmark Holdings PLC entered into an exclusive worldwide license agreement with Saiba Animal Health GmbH to develop and commercialize the CAD vaccine (since termed VC002). In May 2017, HypoPet AG merged with Saiba Animal Health and the CAD vaccine became part of HypoPet’s product pipeline.

About canine atopic dermatitis
Canine atopic dermatitis (CAD) is an allergic disease that affects up to 10 % of dogs. It stems from a genetic predisposition to develop allergic symptoms following exposure to substances that are usually harmless. Dogs afflicted with CAD develop itching, excessive scratching and rubbing, hair loss, greasy or flaky skin with a foul odor, excessive chewing on the paws, groin and armpits. Over time, the affected skin becomes raw, inflamed and infected. Treatment of the condition is life-long and until recently comprised allergen avoidance, symptomatic treatment, desensitization therapy and immunosuppressive therapies. These treatments had limited efficacy and were associated with side effects. Next generation biologic therapies, which includes HypoPet’s therapeutic vaccine, have the potential to provide better treatment options for CAD.
