OCALA, Fla., Nov. 03, 2025 (NYSE American: AIM) ("AIM" or the "Company") today announced that the European Patent Office has officially granted AIM's European Patent No. 4,096,675, titled "Compositions for Treating LONG COVID," covering compositions of matter of AIM's proprietary dsRNAs including, for example, Ampligen® (rintatolimod) for use in the treatment of Long COVID.
"While AIM's immediate and primary focus is to build upon the continued positive results from our late-stage pancreatic cancer clinical program, this new European patent in Long COVID strengthens our intellectual property portfolio while providing additional validation of our belief in Ampligen's potential as a broad-spectrum immunotherapy," commented AIM CEO Thomas K. Equels.
Ampligen is AIM's RNA product candidate designed to modulate the immune system. Data from in vitro, pre-clinical and clinical experiments suggest that Ampligen has a broad-spectrum, early-onset antiviral effect by stimulating a strong innate immune response. The Company has conducted Ampligen experiments in SARS-CoV-1 showing a significant decrease in viral replication. Since the viral genome of SARS-CoV-1 is highly homologousdemonstrating Ampligen to be generally well tolerated and efficacy results offering evidence that Ampligen may reduce fatigue in subjects with post-COVID conditions such as Long COVID. Upon final analysisof the clinical patient data from the AMP-518 clinical trial, the Company believes Ampligen has the potential to be a therapeutic for people with moderate-to-severe Long COVID.
