HEB Hemispherx Biopharma Inc New

Hemispherx Biopharma, Inc. (NYSE American: HEB), an immuno-tech company focused on the research and development of immunological agents to treat multiple types of cancers and immune-deficiency diseases, such as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), today announced that it has changed its name to AIM ImmunoTech Inc. effective September 3, 2019. Additionally, the Company announced that effective September 3, 2019, the Company’s ticker will change to “AIM.” The Company’s common stock will continue to trade on the NYSE American.

“Amplified Immunological Modulation — or ‘AIM’ — is what our company is all about. We are delighted to announce this name change, which we believe better reflects the core mission of the Company — developing synergistic immunological agents in the fields of lethal cancers and severe ME/CFS. We are a small company, fighting hard to bring meaningful cures to sick people currently without hope. Our AIM is to help others by advancing immunology and unlocking the human body’s ability to heal itself, in both ME/CFS and in highly lethal malignancies,” said CEO Thomas K. Equels. “Further, I am very proud of our extensive clinical pipeline and cost-effective approach. We believe the fact that all our oncology trials are paid for by third-party entities through grants from government, NGOs and leading pharmaceutical companies provides significant validation of our clinical potential and a de facto de-risking of the programs.”

Ampligen in Oncology

• Five Ampligen clinical trials that are open for enrollment evaluating the safety and ability of Ampligen to increase the effectiveness of cancer immunotherapy, creating synergy for checkpoint blockade drugs by reprogramming the tumor microenvironment
• Six additional cancer trials in various pre-enrollment stages using Ampligen plus checkpoint blockade or chemokine modulation

Ampligen in ME/CFS

• In the late-stage development/pre-commercial phase for ME/CFS to meet this serious unmet medical need
• An Orphan Drug Designation granted by the U.S. Food and Drug Administration in ME/CFS and the U.S. Food and Drug Administration has granted authorization for ME/CFS compassionate care clinics
• Received Argentine commercial approval for the treatment of severe ME/CFS in 2016

“We remain highly encouraged by the clinical data to date, which supports the biological activity and strong safety profile of Ampligen,” Equels continued. “As such, we look forward to announcing a number of key upcoming catalysts, which we believe will help drive significant shareholder value. As our new name suggests, we are taking AIM at these serious and lethal unmet medical needs.”
