Inventory Disclosure [Abstract]
Inventories	(3) Inventories The Company uses the lower of first-in, first-out (“FIFO”) cost or net realizable value method of accounting for inventory. Commercial sales of Alferon in the U.S. will not resume until new batches of commercial filled and finished product are produced and released by the Food and Drug Administration (“FDA”). While the facility is approved by the FDA under the Biologics License Application (“BLA”) for Alferon, this status will need to be reaffirmed by an FDA pre-approval inspection. The Company also will need the FDA’s approval to release commercial product once it has submitted satisfactory stability and quality release data. Currently, the manufacturing process is on hold and there is no definitive timetable to have the facility back online. The Company estimates it will need approximately $10,000,000 to commence the manufacturing process. Due to the Company extending the timeline of Alferon production to an excess of one year, the Company reclassified Alferon work in process inventory of $1,095,000 to other assets within our balance sheet as of December 31, 2018 and 2017 and due to the high cost estimates to bring the facility back online. The above estimated cost includes additional funds needed for the revalidation process in the Company’s facility to initiate commercial manufacturing, thereby readying itself for an FDA Pre-Approval Inspection. If the Company is unable to gain the necessary FDA approvals related to the manufacturing process and/or final product of new Alferon inventory, its operations most likely will be materially and/or adversely affected. In light of these contingencies, there can be no assurances that the approved Alferon N Injection product will be returned to production on a timely basis, if at all, or that if and when it is again made commercially available, it will return to prior sales levels. The Alferon work in process is currently compliant with our internal protocols, is stored in a controlled state, and the Company regularly monitors the stability of the product. All of these factors contribute to the potential sale of the Alferon work in process, after validation lots have been produced and including a successful pre-approval inspection.
