AIM AIM ImmunoTech Inc

AIM ImmunoTech Inc. (NYSE American: AIM) (“AIM” or the “Company”) today announced its initiation of a plan to advance Ampligen as a vaccine adjuvant for avian influenza as part of the Company’s antiviral priority development pipeline.

AIM has engaged Amarex Clinical Research (“Amarex”), its Clinical Research Organization (“CRO”), with the application and eventual management of a follow-up Investigational New Drug (“IND”) application for the study of a potential avian influenza combination therapy of AIM’s Ampligen and AstraZeneca’s FluMist, a nasal spray vaccine that helps prevent seasonal influenza. AIM is seeking collaborative grants from government and industry to defray the cost of the study.

The new proposed clinical trial would expand upon previous Company-sponsored clinical research at the University of Alabama-Birmingham (“UAB”) (Overton 2014), which indicated that intranasal delivery of Ampligen after the intranasal delivery of the FluMist seasonal influenza vaccine not only increased the immune response to seasonal variants in the vaccine by greater than four-fold, but most importantly induced cross-reactive secretory Immunoglobulin A against highly pathogenic avian influenza virus strains H5N1, H7N9 and H7N3.

See ClinicalTrials.gov: NCT01591473 – “Safety Study of FluMist With and Without Ampligen”

AIM CEO Thomas K. Equels stated: “The avian flu has emerged as a serious and ever-growing public health threat. We believe there is the potential for an influenza vaccination program that provides broader coverage than the currently approved vaccination programs, with the added simplicity of being delivered intranasally. Specifically, there is already both pre-clinical and clinical data which demonstrates potential for synergy between our lead compound Ampligen to provide greater efficacy and potential epitope spreading and cross-reactivity for avian influenza when combined with AstraZeneca’s FluMist vaccine. Based on the UAB clinical data to date, we believe such a combination therapy could also be an effective barrier against avian flu infections.”

This Company’s belief stems directly from the pre-clinical and clinical work performed with Ampligen and multiple influenza variants, some of which supported the conception of the original UAB study.

• Previous pre-clinical work showed that when Ampligen was administered with the then-standard seasonal trivalent flu vaccine — which included influenza A H1N1, influenza A H3N2 and influenza B Shanghai strain — intranasally to laboratory mice, it manifested cross-reactivity of mucosal and serum antibodies against H5N1. Furthermore, to demonstrate whether the H5N1 antibodies generated by intranasal Ampligen combined with intranasal vaccine conferred immunity to H5N1, mice were challenged with three H5N1 variants 14 days after final inoculation. At 14 days post H5N1 challenge, 50% survival protection from influenza A Vietnam strain compared to 0% in uninoculated mice was observed and 100% survival from influenza A Hong Kong strain and influenza A Indonesia strain viruses, compared to 60% and 20% respectively in naïve controls.
• Intranasal delivery of Ampligen in combination with NIBRG14 H5N1 vaccine conferred serum and mucosal antibodies and protected non-human primates from H5N1 symptoms, including lung fibrosis (scarring) and death, when challenged with the homologous H5N1 pathogen. In addition, it also provided neutralizing antibodies against other H5N1 strains, indicating that the intranasal immunization with the Ampligen-combined influenza A H5N1 vaccine can provide non-human primates with cross-protective immunity against influenza A H5N1 virus challenge.
• An AIM-sponsored study to assess the safety, tolerability and biological activity of intranasal Ampligen in humans found that repeated administration in four cohorts of 10 subjects each was generally well-tolerated with no serious treatment-related adverse events.

AIM believes that the totality of this pre-clinical and clinical work to date — combined with the ever-growing threat of Avian influenza — strongly supports its decision to move forward with this second Ampligen and FluMist study in humans.
