Hemispherx Highlights Year-To-Date Progress, Outlines Key Objectives

Posted on: 19 Dec 17

Letter to Shareholders Posted on Website

Revenue Up, Burn Rate Down Dramatically; Progress Cited with FDA Discussions on Ampligen; Manufacturing Facility for FDA-Approved Alferon N Fully Repaired; Immuno-oncology Seen as Major Opportunity

PHILADELPHIA, Dec. 19, 2017 (GLOBE NEWSWIRE) -- Hemispherx Biopharma (NYSE American:HEB) announced the posting of a letter to shareholders on its website,, in which CEO Thomas K. Equels reviews corporate activities progress over the past nine months and outlines key objectives going forward.

The letter appears below:

To our shareholders:

We have achieved significant milestones during the short period of time I have been CEO. We are making steady progress with our plans to commercialize Alferon N Injection®, expand the market opportunities for Ampligen®, and streamline operating infrastructure and related costs to put us on a stronger financial footing.

Drastically reduced our cash burn rate while aggressively opening new opportunities for Ampligen in the fast-growing field of immuno-oncology

Specifically, revenue for the first nine months of 2017 totaled $387,000, a greater than five-fold increase compared to $76,000 a year ago, and our net loss for the quarter ended September 30, 2017 decreased by more than 50 percent to $1.3 million from $2.9 million a year-ago. The more than fifty-percent decrease is attributed to a reduction of operating expenses of $0.5 million and an increase in revenue of $1.4 million resulting from the revaluation of the redeemable warrants as of September 30, 2017.  Operating costs and expenses, inclusive of research and development, were $2.7 million in the quarter just ended vs. $3.2 million in the year-ago period. The bottom line is we have achieved important milestones and reduced expenses as compared to prior years.

Moreover, we have tremendous confidence in our product portfolio. I believe Ampligen is the ‘shape of things to come’ in immunology. It is poised to potentially become an important therapy in the rapidly expanding field of immuno-oncology. It is the only activator of Toll-like Receptor 3 with a well-established safety record.

Some of the key developments in our Ampligen program have included regulatory approval in one of South America’s largest markets, a stepped-up collaboration to support a regulatory submission for ME/CFS in Canada, positive results from an intranasal safety study, and several new initiatives to leverage the immunotherapeutic properties of Ampligen in state-of-the-art cancer treatment strategies.

Key Advancements For Ampligen

  • Ampligen has been approved in Argentina for severely debilitated Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) patients and we are pursuing similar approvals in Chile and Peru. We are collaborating with Millions Missing Canada to bring Ampligen to Canadians suffering from ME/CFS. In addition, we are in continuing discussions with the FDA regarding our New Drug Application in ME/CFS. Ampligen is the only drug to have completed a Phase 3 clinical trial in the U.S. in ME/CFS, a condition which according to the Center for Disease Control (CDC) afflicts more than one million people in this country.  Taking into account that trial’s results, and the FDA’s indication at our last meeting that they would be open and receptive to review a proposal by the Sponsor (Hemispherx), we plan to seek approval tied to a protocol we are developing for conducting a study, limiting enrollment to patients with high responder potential.

  • Earlier this year we began supplying Ampligen for pancreatic cancer patients in an Early Access Program (EAP) in the Netherlands managed by myTomorrows, an international leader in providing physicians with early access to experimental drugs. 

  • Significant research at the University of Pittsburgh and Roswell Park Cancer Center is underway to determine the extent to which Ampligen alone and in combination with other agents may prime the tumor microenvironment in ways that could improve the lethality of cancer-killing T cells in conjunction with PD-1 and PD-L1 checkpoint inhibitors, such as Keytruda from Merck and Opdivo from Bristol-Myers Squibb. The success of these studies and others being planned could lead to a significant advance in the fast-growing field of immuno-oncology.

  • Attracting a greater number of antigen-specific cytotoxic T cells into the tumor microenvironment while increasing their ratio to immunosuppressive Treg cells is expected to significantly improve the overall effectiveness of checkpoint inhibitors, a new class of drugs designed to destroy the blocking mechanisms that prevent effector cytotoxic T cells from attacking tumor cells. The use of checkpoint inhibitors is growing rapidly (Cowan & Co. projects sales to grow to $30 billion annually by 2020) and we are developing Ampligen with the anticipation of it becoming an integral part of combinational therapies tapping into that growth.

  • We recently commenced full data analysis of an intranasal vaccine study of Ampligen plus FluMist.  Intranasal Ampligen was generally well-tolerated in this study. Numerous studies have shown that Ampligen is a generally well-tolerated and highly selective Toll-like Receptor 3 agonist capable of inducing the innate immune responses needed for adaptive protective immunity. Monkeys immunized with H5N1 vaccine and Ampligen showed enhanced protection against a highly pathogenic H5N1 virus. Mouse models showed Ampligen generates cross-protection against 3 clades of highly pathogenic H5N1 using a seasonal vaccine. The human intranasal safety study demonstrated antibodies against viral strains not present in the immunizing vaccine. Highly pathogenic bird strains of influenza remain a clear and present human danger for a devastating influenza pandemic. Only one or two mutations in the viral attachment receptor of these highly pathogenic bird influenza viruses are required to provide an easily spread and highly lethal virus in humans. The clinical data from our FluMist study extends the mouse and monkey studies. The experimental data suggests that intranasal immunization with Ampligen may provide a rapid and well tolerated means of protection in at-risk humans. We are currently exploring co-development partnerships with vaccine producers. 

Our cancer-directed programs with Ampligen build on a safety data base consisting of approximately 100,000 Ampligen doses, primarily in ME/CFS trials, and earlier Phase 1/2 oncology clinical studies including renal cell carcinoma and metastatic melanoma.

We have finalized a commercial-scale “fill and finish” production agreement to fulfill our forecasts for Ampligen demand in 2018. New inventory is planned to be available 2Q18 for Argentina, for US based clinical studies and for Early Access Program sales in Europe.

New Jersey manufacturing facility - completed work to resume production and awaiting funding and FDA re-certification

It will cost about $10 million to put the Alferon manufacturing line at the New Brunswick, NJ plant back into full operation. We are exploring several avenues for funding. While the insurance has fully covered the physical damage to the plant, we are still working to get additional coverage under policy provisions which will help us defray the costs of restarting production. In the interim we are also examining other options, including co-development opportunities.As many of you know, we experienced a major setback in our Alferon N Injection program when a broken water main for the sprinkler system flooded key sections of our New Jersey manufacturing facility. Insurance has reimbursed us for all the physical damage and all repair and reconstruction work has been completed. The next step is FDA re-certification of the facility.

We have an agreement with Asembia, a leading national supplier to specialty pharmacies, to market and distribute the product in the U.S. when manufacturing resumes.  Alferon N is approved for refractory or recurring external genital warts in the US and Argentina, and is also approved in Argentina for any patient refractory to recombinant interferon.

In summary, the stage is set for Hemispherx to capitalize on significant new opportunities during the balance of this year and 2018. We have repaired our flood-damaged manufacturing facility.  It is now ready, pending additional start-up funding and FDA certification, to produce FDA-approved Alferon N Injection. A marketing and distribution agreement is in place. We have secured our first country approval for Ampligen in ME/CFS and we expect several more in the coming years. We are steadily expanding our EAP strategy for Ampligen internationally.  We are making progress in defining the next steps for FDA registration of Ampligen. We are aggressively opening new opportunities for Ampligen in the fast-growing field of immuno-oncology.  All of this is being accomplished with cautious use of capital and our commitment to increasing shareholder value. Our new management motto is EFFICIENT EXECUTION OF PRIORITY GOALS. We have accomplished all the above while slashing the burn rate by 50 percent.

I look forward to keeping you updated on our progress.
