While we have received regulatory approval for the commercialization of Ampligen in Argentina (pending additional release testing and subsequent steps), all of our drugs and associated technologies, other than Alferon N Injection, are investigational in the U.S. and must receive prior regulatory approval by appropriate regulatory authorities for commercial distribution and sale and are currently legally available only through clinical trials in the U.S. with specified disorders. At present, Alferon N Injection is approved for the intralesional treatment of refractory or recurring external genital warts in patients 18 years of age or older. However, it is not at present available for purchase on the market. Use of Alferon N Injection for other indications will require regulatory approval in the United States and abroad.
Our products, including Ampligen, are subject to extensive regulation by numerous governmental authorities in the U.S. and other countries, including, but not limited to, the U.S. FDA, the Health Protection Branch ("HPB") of Canada, the Agency for the European Medicines Agency ("EMA") in Europe; and the Administracion Nacional de Medicamentos, Alimentos y Tecnologia Medica ("ANMAT") in Argentina. Obtaining regulatory approvals is a rigorous and lengthy process and requires the expenditure of substantial resources. In order to obtain final regulatory approval of a new drug, we must demonstrate to the satisfaction of the regulatory agency that the product is safe and effective for its intended uses and that we are capable of manufacturing the product to the applicable regulatory standards. We require regulatory approval in order to market Ampligen or any other proposed product and receive product revenues or royalties. We cannot assure you that Ampligen will ultimately be demonstrated to be safe and efficacious. While Ampligen is authorized for use in clinical trials in the U.S., we cannot assure you that additional clinical trial approvals will be authorized in the United States or in other countries, in a timely fashion or at all, or that we will complete these clinical trials. In addition, although Ampligen has been authorized by the FDA for treatment use under certain conditions, including provision for cost recovery, there can be no assurance that such authorization will continue in effect.
While we received approval of our Argentinian NDA from ANMAT for commercial sale of rintatolimod (U.S. tradename: Ampligen) in the Argentine Republic for the treatment of severe ME/CFS, ANMAT approval is only an initial, but important, step in the overall successful commercialization of our product. In September 2019, we received clearance from the FDA to ship Ampligen to Argentina for the commercial launch and subsequent sales. However, there are a number of additional actions that must occur before we would be able to commence commercial sales in Argentina. For example, Ampligen is still in the process of release testing the product that has already been sent.
The FDA's regulatory review and approval process is extensive, lengthy, expensive and inherently uncertain. To receive approval for a product candidate, we must, among other things, demonstrate to the FDA's satisfaction with substantial evidence from well-controlled pre-clinical and clinical trials that the product candidate is both safe and effective for each indication for which approval is sought. Before we can sell Ampligen for any use or promote Alferon N Injection for any use other than as Alferon N Injection for treatment of refractory or recurring genital warts, we will need to file the appropriate NDA with the FDA in the U.S. and the appropriate regulatory agency outside of the U.S. where we intend to market and sell such products. At present the only NDA we have filed with the FDA is the NDA for the use of Ampligen to treat CFS. The FDA issued a Complete Response Letter ("CRL") in February 2013 for this NDA and provided recommendations to address certain outstanding issues before they could approve Ampligen for Commercial Sales. The Agency stated that the submitted data do not provide substantial evidence of efficacy of Ampligen for the treatment of CFS and that the data do not provide sufficient information to determine whether the product is safe for use in CFS due to the limited size of the safety database and multiple discrepancies within the submitted data. The FDA indicated that we needed to conduct additional work. Therefore, ultimate FDA approval, if any, may be delayed indefinitely and may require us to expend more resources than we have available. It is also possible that additional studies, if performed and completed, may not be successful or considered sufficient by the FDA for approval or even to make our applications approvable. If any of these outcomes occur, we may be forced to abandon one or more of our future applications for approval, which might significantly harm our business and prospects. As a result, we cannot predict if or when we might receive regulatory approval for the use of Ampligen to treat CFS or for the use of any other products. Even if regulatory approval from the FDA is received for the use of Ampligen to treat CFS or eventually, for the use of any other product, any approvals that we obtain could contain significant limitations in the form of narrow indications, patient populations, warnings, precautions or contra-indications or other conditions of use, or the requirement that we implement a risk evaluation and mitigation strategy. In such an event, our ability to generate revenues from such products could be greatly reduced and our business could be harmed.
If we are unable to gain necessary FDA approvals related to Ampligen and Alferon N Injection on a timely basis, or we are unable to generate the additional data, successfully complete inspections or obtain approvals as required by the FDA on a timely manner, or at all, or determine that any of our clinical studies are not cost/justified to undertake or if, for that or any other reason, Ampligen, Alferon N Injection or one of our other products or production processes do not receive necessary regulatory approval in the U.S. or elsewhere, our operations most likely will be materially and/or adversely affected.
Generally, obtaining approval of an NDA by the FDA, or a comparable foreign regulatory authority, is inherently uncertain. Even after completing clinical trials and other studies, a product candidate could fail to receive regulatory approval for many reasons, including the following:
- not be able to demonstrate to the satisfaction of the FDA that our product candidate is safe and effective for any indication; - the FDA may disagree with the design or implementation of our clinical trials or other studies; - the results of the clinical trials or other studies may not demonstrate that a product candidate's clinical and other benefits outweigh its safety risks; - the FDA may disagree with our interpretation of data from clinical trials or other studies; - the data collected from clinical trials and other studies of a product candidate may not be sufficient to support the submission of an NDA;- the approval policies or regulations of the FDA may significantly change in a manner rendering our clinical and other study data insufficient for approval; and - the FDA may not approve the proposed manufacturing processes and facilities for a product candidate.
