The global market demand for cyclodextrins continues to grow. A recent study (by QY Research Cyclodextrin Research Center) cites global demand as having almost doubled between 2009 and 2013 from 191,900 metric tons to 353,160 metric tons. Within the last 10 years, many more European countries have approved the use of cyclodextrins in food products. In the United States, major starch companies are renewing their earlier interest in cyclodextrins as food and nutraceutical additives. We believe the food additive industry world-wide will continue to increase its use of cyclodextrins.
Natural cyclodextrins have been confirmed to be generally recognized as safe (GRAS) in most of the world, now including the U.S. Moreover, approvals of products containing cyclodextrins by the U.S. Food and Drug Administration (FDA) since 2001 suggest that regulatory approval for new products may be easier in the future. In 2001, Janssen Pharmaceutica, now a subsidiary of Johnson & Johnson, received FDA approval to market Sporanox®, an antifungal which contained hydroxypropyl beta cyclodextrin as an excipient. In 2008, one of our clients used our product, Trappsol® hydroxypropyl beta cyclodextrin, in an FDA approved compassionate use investigational new drug protocol for the treatment of Niemann-Pick Type C disease. We now sell this product under our trademark Trappsol® Cyclo™. Our customer successfully applied to the FDA to designate Trappsol® Cyclo™ as an orphan drug in the treatment of Niemann Pick Type C disease in support of an Investigational New Drug protocol. Under the Orphan Drug Act, companies that develop a drug for a disorder affecting fewer than 200,000 people in the United States may seek designation as an orphan drug and, if such application is approved, they have the ability to sell it exclusively for seven years, and may get clinical trial tax incentives. On May 17, 2010, the FDA designated Trappsol® Cyclo™ as an orphan drug for the treatment of Niemann-Pick Type C disease.
Applications of cyclodextrins in personal products and for industrial uses have appeared in many patents and patent applications. Cyclodextrins are used in numerous brand-name household goods, including fabric softeners and air fresheners. With increased manufacturing capacity and supply the prices of the natural cyclodextrins have decreased to the point that use of these materials is considered in even the most price sensitive goods. We believe this will result in increasing demand for commercial uses of cyclodextrins.
In Japan, at least twelve pharmaceutical preparations are now marketed which contain cyclodextrins; there are also multiple products in Europe and the United States. The cyclodextrins permit the use of all routes of administration. Ease of delivery and improved bioavailability of such well-known drugs as nitroglycerin, dexamethasone, PGE(1&2), and cephalosporin permit these “old” drugs to command new market share and sometimes new patent lives. Because of the value added, it is management’s opinion that the dollar value of the worldwide market for products containing cyclodextrins and for complexes of cyclodextrins can be a hundred times that of the market sales of the cyclodextrin itself. This value increment portends opportunities for company growth in the pharmaceutical grade cyclodextrins and in custom cyclodextrin complexes.
