Ampligen® has orphan drug status in the U.S. for treatment of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome
Hemispherx Biopharma, Inc. (NYSE American:HEB), focused on pharmaceutical research, today commented on the overall market opportunity for its Ampligen®
drug candidate in treating Myalgic Encephalomyelitis/Chronic Fatigue
Syndrome (ME/CFS), given the recent announcement by clinicians
regarding the failure of Rituximab ME/CFS trial in Europe. See Link:

ME/CFS is a serious, debilitating condition that imposes a burden of
illness on millions of people in the U.S. and around the world, leaving
hundreds of thousands seriously disabled worldwide.
In the U.S., there are no approved treatments for ME/CFS. Ampligen®, which enjoys orphan drug status for ME/CFS, is the only drug in late-stage clinical development. The company has completed CFS Phase I/II/III studies in the U.S. for Ampligen®, which has demonstrated clinically significant improvements in patient exercise performance in two randomized, placebo-controlled pivotal trials and the FDA is requiring a confirmatory trial. Ampligen® is already approved in Argentina, where it is the first and only drug ever approved anywhere in the world as a therapy for ME/CFS.
The Company is focusing its NDA and confirmatory trials in the U.S. for severely debilitated ME/CFS patients on a target population of approximately ~100,000. The company estimates that a market penetration of only 10 percent would result in peak annual sales of over $500 million1. Hemispherx is in the final stages of producing commercial lots with some of its recently acquired funding, which are needed to launch Ampligen® in Argentina. Increasing Ampligen production is also essential for upcoming clinical activities in both ME/CFS and oncology to move forward in the U.S, Europe and Canada.
Dr. Daniel Peterson, a world renowned independent expert in the treatment of ME/CFS and in the clinical use of Ampligen® (or rintatolimod), states that it “… is a potentially useful drug for a subset of severely ill ME/CFS patients to improve quality of life and functional status. Based on extensive clinical experience and testing, rintatolimod has an excellent safety profile. In addition, there are clear outcome measures that can be used to assess the drug’s efficacy in planned confirmatory trials.”
“We are optimistic about the prospects for Ampligen® and its potential to help tens of thousands of people who currently have no treatment options. Our company is focused on getting Ampligen® to the final stage for regulatory approval for ME/CFS in the U.S. and preparing for an ME/CFS commercial launch in Argentina,” said Thomas K. Equels, chief executive officer of the company. Mr. Equels recently wrote an address to Hemispherx’s Stockholders and Employees about the importance of seeking an approved therapy for ME/CFS.
