Low Dose Immunotherapy Status
in the United States


     EPD was administered in the United States for several years under an Investigational Review Board (IRB) study. The IRB study showed that EPD was extremely safe (safer than "conventional" allergy shots) and effective for 80% of the people treated for most allergic conditions. When the IRB expired, application was made with the FDA for Investigational New Drug (IND) status for EPD. The IND application was denied and in April, 2001 the FDA "shut down" EPD.

     This FDA action abruptly ended all EPD treatment in the United States, leaving thousands of desperately ill citizens with no access to any effective treatment for their problems (Most EPD patients are taking it because other treatments have failed to help them). When something essential to life is taken away, we must act, so a patient group called The EPD Patient Alliance was formed. A letter-writing campaign was organized, and many, many EPD patients wrote to the FDA, their congressmen, and the President.

     During the summer of 2001, as it became apparent that the British manufacturer’s IND application was going to take some time to be submitted and would probably exclude most former EPD patients, some patients researched the possibility of directly importing EPD for personal use. The FDA website section on "Personal Importation and Use of Unapproved Products" said that in cases of dire need the FDA may allow patients to import for personal use a less-than-three-month supply of unapproved products in baggage or by mail with the appropriate documentation. Therefore, personal importation seemed like a solution to the problems. However, the FDA had already put EPD on "Import Alert" and told us that this makes it "illegal" to import EPD for personal use.

     At this point, things looked pretty grim for EPD patients, especially those who live far from the Canadian border. However, as Christian EPD patients petitioned the President, the FDA, and members of Congress for help with our problem, we also remembered Who is really in control, and petitioned Him as well. "The king’s heart is in the hand of the Lord; He directs it like a watercourse wherever He pleases." (Proverbs 21:1) We formed a prayer group that is still "up and running."

     Our prayers were answered, and an American-made alternative to EPD now exists. This injection is called LDA (for Low Dose Allergens) and is based on the same principle as EPD, although it is in many ways different and improved. LDA is compounded in a licensed American pharmacy from American-made antigens manufactured in FDA licensed laboratories. The antigens used are the same as in conventional allergy desensitization shots, but in very low concentrations. In addition to common allergens, LDA contains uniquely American antigens which are not present in EPD such as cottonwood, sage, mountain juniper, some New World evergreens, American perfumes, "new" foods such as avocado, etc. Because LDA is so new, there is not much data available on it yet, but many patients I have talked to have had very good results with LDA. My personal experience is that I had mediocre results on food allergies in over 35 shots during 9 years of treatment with EPD. It was always three steps forward and then two steps back; with some shots I’d be able to add a food or two to my diet, and then I might "lose" it with the next shot. After 9 years of treatment, I was no longer starving, for which I was very grateful. My diet consisted of game meats, less-common kinds of fish, some nuts, some vegetables, and some fruits. After one shot of LDA I have been able add several new foods to my diet including some very "normal" ones such as legumes and dairy products. My son is also doing very well with his first shot of LDA. In fact, he is doing better on pollen than he did with EPD. In the July-August "Mastering Food Allergies" article on EPD, it was explained that one of the reasons EPD worked better than other types of desensitization was because all of the patient’s allergies were treated at once. In my opinion, I expect LDA to work better than EPD for American patients because it is designed to "fit" the allergic exposures Americans experience rather than the exposures that the British experience.

     A new IND for EPD was submitted to the FDA in the fall of 2001 and was accepted. The IND study, which will be for seasonal hayfever only, is expected to begin in 2003. It will probably be several years before EPD could be approved for food allergies.
