Ainos Publishes Preclinical Data Demonstrating its VELDONA Formulation's Potential as Treatment Candidates for the Most Common Medical Conditions for Companion Animals

VELDONA® interferon-alpha formulation has shown potential as a treatment candidate for feline chronic gingivostomatitis and canine atopic dermatitis

Ainos advances its product pipeline as it targets commencing clinical studies duringthe second quarter of 2023

SAN DIEGO,Nov. 21,2022 -- Ainos,Inc. (NASDAQ: AIMD,AIMDW) ("Ainos",or the "Company"),a diversified medtech company focused on the development of novel point-of-care testing,low-dose interferon therapeutics,and synthetic RNA-driven preventative medicine,today announced that it has published preclinical data demonstrating the potential of its low-dose oral interferon-alpha (IFNα) formulation,VELDONA®,as treatment candidates for the two most common medical conditions for dogs and cats. The preclinical data can be accessed here.

Ainos intends to begin clinical studies to assess VELDONA®'s potential use in the treatment of feline chronic gingivostomatitis (FCGS) and canine atopic dermatitis (CAD) during the second quarter of 2023. The Company initially applied VELDONA® to feline coronavirus (FCoV)-infected fcwf-4 (feline microphage) systems to determine potency and dose translation. According to the results,the EC50 value of VELDONA® was 1062 IU/mL (5.29x10-3 ng/ml). Based on VELDONA®'s effective antiviral efficacy,the Company is planning an expansion of its use for the treatment of humans to treatment of animals. Ainos is designing dose-finding field studies to identify optimal VELDONA® dose via oromucosal administration for feline FCGS and canine CAD.

A report compiled by Research and Markets and published by Mordor Intelligence shows that the global pet dental health market is projected to grow at a CAGR of 6.2%,reaching US$9.98 billion by 2030.The dog market segment accounted for the largest revenue share at over 55.0%,and thecatmarket segment is anticipated to expand at a CAGR of 6.9%. It is also reported that the global CADmarket size is projected to grow at a CAGR of 12.6% to reach US$221.20 billion by 2027.

FCGS is a severe oral mucosal inflammatory disease afflicting cats,while CAD is an inflammatory skin disease found in dogs. Both of these diseases are common,difficult to diagnose,and have complex multifactorial etiologies,with complex causes including environmental factors,bacterial or viral infections,and aberrant host immune systems. Once infected,the host animal will display an inappropriate immune response which may require life-long medication to control.

Estimates of the prevalence of FCGS among cats range from 0.7% to 12% and the prevalence of CAD among dogs is estimated to be between 3% and 15%. The estimated ownership of cats and dogs in the U.S. numbers 85.5 million and 78 million respectively,suggesting up to 10.3 million cats suffer from FCGS and up to 11.7 million dogs suffer from CAD. The rate of companion animal ownership in the U.S. continues to increase,especially among young people. Approximately 44% of all U.S. households have a dog and 35% of U.S. households have a cat.

Presently,medical management of FCGS and CAD remains highly diverse,and is often dependent upon comorbidities in individual cases. In general,existing pharmacotherapies for FCGS and CAD include antibiotics,antihistamines,and immunosuppressive agents such as corticosteroids or cyclosporine,which are often the first line of treatment for afflicted animals. However,the long-term adverse effects of these immunosuppressive agents are serious,and include type II diabetes and opportunistic infections. At present,no medication exists for animals that are not responsive to anti-inflammatory or immunosuppressive treatments,and there is no ideal long-term solution available to pet owners.

Over the course of several years,the Company's VELDONA® formulation exhibited systemic effects in mice,cats,dogs,rats,guinea pigs,horses,cattle,and swine,involving such indications as feed efficiency in swine and lethal virus infection in other species (e.g.,canine parvovirus,horse herpes virus,and feline coronavirus). These in vivo studies indicate that VELDONA® can have a therapeutic or prophylactic effect at sites distal to the oral mucosa. VELDONA® modulates systemic and mucosal immunity in the absence of serious adverse effects,first-pass effect and proteolytic degradation associated with other administration routes.

Chun-Hsien Tsai,Ainos' Chairman of the Board,President,and Chief Executive Officer commented,"Following our acceleration of five VELDONA® candidates to Phase 3 trials and commercialization,this preclinical data indicates the formulation's promising potential for an array of applications. It also demonstrates that we are successfully executing on our strategy to broaden VELDONA®'s market,and our progress in advancing the monetization of our innovative product pipeline. More and more people are taking to pet ownership,and it has become all the more important that pet owners have access to safe and effective solutions for their animals' medical issues. As we look ahead to the process of conducting clinical trials to assess VELDONA®'s potential use in the treatment of FCGS and CAD,we are proud to be able to offer a potential treatment for two conditions that combined affect millions of creatures."
