Ainos Announces Positive Results from Preclinical Studies of Its Low-dose Oral Interferon Formulation Against COVID-19

Hamsters Receiving Ainos’ VELDONA Formulation Demonstrate Protection from COVID-19 Based on Prespecified Indicators of Clinical Outcomes

AN DIEGO, CA / ACCESSWIRE / June 27, 2022 / Ainos, Inc. (OTC PINK:AIMD) ("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 the topline results from its COVID-19 antiviral efficacy study in hamsters (the “Study”). The available results show that its low-dose oral interferon alpha (“IFN-α”) formulation, VELDONA, has a protective effect on lungs infected with the SARS-CoV-2 (the “Delta variant”) virus by regulating the immune response, thus expediting recovery of infected animals. The Company will begin to prepare the application documents for U.S. FDA Phase 2/3 clinical trials. Further information regarding the Study can be found on the Company’s  website (

The Study evaluates the effectiveness of VELDONA over a seven-day course of treatment of Delta-variant-infected hamsters. Compared with hamsters in the control group receiving solution without VELDONA (the “Control Group”), the hamsters in the group receiving solution with VELDONA (the “VELDONA Group”) demonstrated resistance to body weight loss during the first four days, then showed a similar recovery trend in the following two days. The body weights of the hamsters in the VELDONA Group remained more stable than those of the hamsters in the Control Group. Among the symptoms exhibited by hamsters infected with SARS-CoV-2 are interferon dysregulation and loss of body weight. VELDONA increases the secretion of interferon in the body, thereby enhancing immunoreaction.

Percentage of Weight Change

Delta variant viral infection mainly occurs in the upper respiratory tract, but in severe cases it will extend to the lower respiratory tract (i.e., the lungs) causing serious irreversible complications. The Study found that on the sixth day after infection, the amount of virus in the nasal cavities of the hamsters in the VELDONA Group declined significantly, with a maximum reduction ratio of 551.16. More importantly, hamsters in the VELDONA Group had less virus present in the lungs on the third day, and on the sixth day, the hamsters in the VELDONA Group demonstrated a significant reduction in virus, with a maximum reduction ratio of 720510.66.


Viral Load Determination

For pathological indicators, on the sixth day, the hamsters in the VELDONA Group showed 20-30% mixed-cellular inflammation, peribronchial infiltration, and perivascular infiltration, compared to 40-50% in the Control Group. Hamsters in the VELDONA Group in general showed promising results in treating indicators of mild/moderate COVID-19 infection, indicating viral clearance in moderate severity pneumonia (40-50%). The viral qPCR showed viral load (0-6175) in the VELDONA Group compared to viral load (7-21258) in the Control Group.

“A pre-clinical animal study we conducted since March of this year validated the effectiveness of our low-dose oral interferon to protect against COVID-19. We replicated this study in May, with double the sample size, and obtained the same confirmative outcomes. These consistent results support the efficacy potential in inducing significant systemic immunomodulatory to fight against the COVID-19 virus. We believe that VELDONA may have the potential to become an important tool and a viable solution for the treatment of COVID-19 and other viral infections in the future. In addition, we also want to thank both the Taiwan Ministry of Science and Technology and the Emerging Infectious Disease Core Facility Platform of the National Core Facility for Biopharmaceuticals (NCFB) for their support and professional technical services provided in the Study.” said Chun-Hsien Tsai, Ainos’ Chairman of the Board, President, and Chief Executive Officer.
