TECHNICAL FIELDThat this application is generally related to the delivery of immunomodulators to a patient.
BACKGROUNDImmunotherapy (IT) is recognized as one of the most curative treatment for allergies. By exposing the immune system to slowly increasing concentrations of immunomodulators such as an allergen or antigen, it will eventually stabilize and regain control the portion that is hypersensitive to the allergen or antigen. In general, immunotherapy is the “treatment of disease by inducing, enhancing, or suppressing an immune response.” Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies. The active agents of immunotherapy are collectively called immunomodulators. They are a diverse array of recombinant, synthetic and natural preparations, often cytokines.
Immunotherapy involved in the treatment of allergies is a type of suppression immunotherapy, often termed desensitization or hypo-sensitization. This is compared with allergy treatments such as antihistamines or corticosteroids which treat only the symptoms of allergic disease. Immunotherapy is the only available treatment that can modify the natural course of the allergies, by reducing sensitivity to the immunomodulators such as antigens or allergens. An antigen and an allergen can both cause one's immune system to respond. An allergen is an antigen, but not all antigens are allergens. An antigen is any substance that is capable of causing one's immune system to produce antibodies. They are typically organic, or living, produced proteins. An allergen is any antigen that causes an allergic reaction. A non-allergen antigen could be a bacteria, virus, parasite, or fungus that causes an infection. This could also be something else that causes antibody immune system response, like toxins, chemicals, tissue cells involved in transplants or blood cells from a blood transfusion. An allergen is an environmentally produced substance that causes an allergic reaction, although the substance may not be harmful. Allergens cause no reactions in some individuals, while possibly causing a hypersensitive reaction in others. Common allergens include such things as pollen, plants, smoke, feathers, perfumes, dust mites, toxic mold, food, drugs, animal dander, and insect bites and stings.
The exact mechanisms of how IT works are not fully understood, but they involve shifting a patient's immune response from a predominantly “allergic” T-lymphocyte response to a “non-allergic” T-lymphocyte response.
Current accepted processes for performing allergy immunotherapy include injecting immunomodulator matter in the form of antigen material into patient subjects. This is referred to as subcutaneous immunotherapy (SCIT), requiring a patient to visit a doctor's office for weekly injections. It's is very expensive and time-consuming. A second technique, sublingual immunotherapy (SLIT), involves the application of allergy extracts (antigens), and allergens placed into a pill form and swallowed by the patient or disposed in “allergy drops” which are placed under the tongue for the allergens/antigens to be absorbed into the oral mucosa. Transdermal patches may have been used without much success and mostly were used for patch testing to see if a patient reacts to various chemicals or allergens.
Of the people who start traditional subcutaneous injected immunotherapy (SCIT), 90% fail to complete their therapy due to needle fatigue and not being able to see a doctor in their office once or more per week for several years. Further, doctors charge for every one of those visits. Further, doctors trained to give injections for allergy are concentrated in high population and upper middle class places. People in rural areas and people who do not live in upper middle class areas cannot get to an allergist for shots. Consider an inner city kid having to ride public transportation and pay a high copay just to get a high risk injection if an alternative therapy were available!
Allergies are also linked to depression and suicide and are among the top ten reasons for missed work and lost productivity. Lastly, allergies and asthma result in billions of dollars in lost productivity and healthcare costs among the 90% of allergy patients that either never get immunotherapy or fail immunotherapy delivered under its current administration methods.
Currently, allergens are not readily reimbursed when received from a pharmacist for the simple reason that the National Drug Code (NDC) code is not included in the database to which the pharmacist has access. Without an NDC code in the database, the pharmacist cannot access that information. By not being able to access information, the pharmacist cannot interface with a benefits provider for reimbursements nor can they have access to the Average Wholesale Price (AWP), which is the benchmark that has been used for many years for pricing and reimbursement of prescription drugs for both government and private payers. Initially, this AWP was intended to represent the average price that wholesalers used to sell medications to providers, such as physicians, pharmacies, and other customers. However, the AWP is not a true representation of actual market prices for either generic or brand drug products. AWP has often been compared to the “list price” or “sticker price”, meaning it is an elevated drug price that is rarely what is actually paid. AWP is not a government-regulated figure, does not include buyer volume discounts or rebates often involved in prescription drug sales, and is subject to fraudulent manipulation by manufacturers or even wholesalers. As such, the AWP, while used throughout the industry, is a controversial pricing benchmark.
The AWP may be determined by several different methods. The drug manufacturer may report the AWP to the individual publisher of drug pricing data, such as Medi-Span. The AWP may also be calculated by the publisher based upon a mark-up specified by the manufacturer that is applied to the wholesale acquisition cost (WAC) or direct price (DIRP). The WAC is the manufacturer's list price of the drug when sold to the wholesaler, while the DIRP is the manufacturer's list price when sold to non-wholesalers. Typically a 20% mark-up is applied to the manufacturer-supplied WAC or DIRP, which results in the AWP figure.
The publishers then in turn sell these published AWPs to government, private insurance, and other buyers of prescription drugs, who use these data tables to determine reimbursement and retail prices. Because AWP is a component of the formulas used to determine reimbursement, elevated AWP numbers can drastically increase the dollar amount that government, private insurance programs, and consumers with coinsurance must pay.
Pharmacies typically buy drugs from a wholesaler and then sell them to the public. Many patients have coinsurance or copayments, where they only pay for a portion of their prescription cost. The insurance company then pays the rest of the cost (the reimbursement) to the pharmacy. Insurance companies include prescription benefit manager (PBM), health maintenance organization (HMO) or government programs, such as Medicaid or Medicare Part B or D. In addition, the pharmacy receives a dispensing fee for filling the prescription. Fees are, for example, set between $3 to $5 per prescription, but may vary by state.
Reimbursements are based on AWPs. However, pharmacies purchase drugs based on the WAC. The difference between the WAC (what the pharmacy actually paid for the drug) and the reimbursement from insurance (based on AWP) is known as the spread, and equates to the profit that the pharmacy receives.
Market pricing on brand drugs tend to be about 16.6 percent less than the AWP. However, the relation of AWP to generic pricing is not clear. Older generics tend to have a large spread between the AWP and WAC, which in turn gives a large spread, and higher profit margins for the pharmacy or other provider of the drug. Many payers, such as PBMS or HMOs, will determine a maximum allowable cost (MAC) pricing on generics to avoid being overcharged. Newer generic products, compared to older generics, may not have as favorable of a spread, thus the need for MAC.
Collusion between AWP publishers and wholesalers to artificially inflate the AWP, and in turn increase the spread, has led to court cases in the U.S. In these cases, it was alleged that increasing the spread benefited the wholesaler because customers (pharmacies and large institutions) were more likely to buy from them than a competing wholesaler where the spread was not as desirable. The publisher of AWPs profited because pharmacies were more likely to buy the pricing lists from the publisher that noted the higher AWPs used in calculating the spread, than to buy them from other publishers with lower AWPs. Due to this pricing fraud, many payers, including government payers, are no longer using AWP for pricing, and are switching to other more transparent pricing benchmarks, such as WAC or AMP (average manufacturers price). However, AWP may still be found in use in the U.S. because it has been the standard for decades.
However, in order for a pharmacist to access the AWP and to be able to interface with benefits providers, the product associated with an NDC must be in the database. Currently, allergens are on item that does not exist in the database.
SUMMARYIn one embodiment, a method for delivering allergens to a pharmacist in a pre-diluted kit form is provided. The method comprises providing a bulk container of base concentrate antigen containing at least one antigen at a predetermined concentrated level, providing a plurality of sequential bulk containers each containing a fixed amount of a carrier solution for diluting antigens. The method further comprises creating a sequential and more diluted sequence of antigens by the steps of a) dispensing from the bowl container a fixed amount of the base concentrate antigen containing at least one the antigen at the predetermined concentrated level to a first of the sequential bulk containers for being diluted in the carrier contained therein, b) dispensing a fixed amount of the contents of the first of the sequential bulk containers to a next of the sequential bulk containers for being diluted in the carrier contained therein, and c) sequentially repeating step b dispensing a fixed amount of the contents of a previous one of the sequential bulk containers to the next of the sequential bulk containers for being diluted in the carrier contained therein until the last of the sequential bulk containers has contents dispense therein from the previous of the sequential bulk containers. The method further comprises providing a plurality of end-use sealable containers that can receive a finite end amount of diluted antigens, dispensing from each of the sequential bulk containers a finite end amount of diluted antigens into one of the plurality of end-use sealable containers, where in the end-use seal containers filled from each of the sequential bulk containers comprises a group of end-use sealable containers associated with each of the sequential bulk containers, sealing each of the end-use containers after diluted antigens are disposed therein, and disposing a select number of the sealed end-use sealable containers from each of the groups of end-use sealable containers into a container comprising a kit to provide a plurality of kits for dispensing to a patient.
For a more complete understanding, reference is now made to the following description taken in conjunction with the accompanying Drawings in which:
Referring now to the drawings, wherein like reference numbers are used herein to designate like elements throughout, the various views and embodiments of a method for delivering immunomodulators to a patient for the treatment of allergies in pre-dilution sets are illustrated and described, and other possible embodiments are described. The figures are not necessarily drawn to scale, and in some instances the drawings have been exaggerated and/or simplified in places for illustrative purposes only. One of ordinary skill in the art will appreciate the many possible applications and variations based on the following examples of possible embodiments.

Allergen extract is typically comprised of a non-allergenic material, a non-allergenic protein and an allergenic protein. The extraction solutions can be aqueous containing saline and phenol which could be a glycerinated solution. The allergen is added, the units of measure are sometimes referred to as “AU” for “allergy units,” typically used for mites. These are referred to as “AU/mL.” For such things as grass and cats, the term “BAU” is used for “bioequivalent units.” For other allergens, the terminology is, for example, 1:20 w/v, which stands for 1 g source material per 20 mL of fluid. The relationship between BAU and 1:20 w/v depends upon the extract. In any event, there is a defined amount of extract contained within the concentrate.
When concentrated extracts are formulated by an authorized vendor, they are typically provided in standardized versions and non-standardized versions. In standardized versions, they typically are provided in a 50% glycerin dilutant. They can either be a single allergen extract or they can be a mix. For example, one can obtain a “9 Southern Grass Mix (concentrate)” which contains equal parts of: 2 Bermuda at 10,000 BAU/mL, P27 7 Grass at 100,000 BAU/mL, and 15 Johnson at 1:20 w/v. For non-standardized extracts, these are typically provided in either a glycerin dilutant or an aqueous dilutant such as saline. They can be a single extract or a mix. Thus, whenever a concentrated extract is referred to hereinbelow, this refers to a formulation that is provided by an authorized vendor that can be diluted in accordance with the processes described hereinbelow. These are typically provided in the 50 mL bottles with a needle compatible.

In general, the typical distribution chain requires that the allergist or other medical professional purchase the base concentrate and then perform the dilution process. However, this procedure typically requires breaking the seal on the base concentrate bottle and then inserting a needle into the base concentrate bottle for the first dilution step. This occurs multiple times. Thus, multiple needles, each being sterile, can be used one time or, more commonly, a single needle is utilized in association with the base concentrate bottle, with the assumption that, since it does not involve insertion into human flesh, it is still sterile. In any event, this needle must penetrate the rubber stopper seal on the base concentrate bottles multiple times. In fact, these bottles could typically be held upside down and they would leak and, once the seal is broken, there is no sterile cover over the rubber stopper. This is a result of the multiple needle piercings of the rubber stopper. This is also the case with the small 5 mL bottles in that each has to be penetrated at least twice in the higher concentrate bottles. Thus, the last bottle that the allergist has would be a 5 mL bottle and this bottle would already have one piercing of the rubber stopper seal in order to provide the initial dilution level into the carrier material, such as saline. Thereafter, a patient might be able to receive 5 or 10 doses from that particular bottle, requiring 5 or 10 more piercings of the rubber stopper. During this time, of course, there is no seal over the rubber stopper.
In order to solve this problem, a process is provided whereby the concentrate bottles are produced from a sterile environment container which Artie has the dilutant provided thereto. This is illustrated in
Once the concentrated level or dilution level in the bottle has been defined, this is then utilized to provide a controlled amount of diluted allergen to a second dilution bottle 216 through a metering valve 218. This is repeated for multiple bottles down the line to a last bottle 220. Thus, there are then provided a plurality of larger vessels with controlled dilution levels at each diluted stage in a sterile environment. Each of these bottles 204, 216 and 220 has associated therewith a control metering valve 222 and a dispensing nozzle 224 that is operable to dispense diluted allergen material into a receptacle. This metering valve 222 and associated nozzle 224 are all approved to interface with an approved bottle.
In the dispensing process, there are provided for each dilution stage a plurality of bottles 230. Each of these bottles has a shape and opening that is approved to be interfaced with the nozzle. Each is passed by the nozzle and an exact amount of diluted material, the allergen, dispense therein. Thereafter, each bottle 230 is then subjected to a Procedure which inserts the rubber stopper and the seal there over. The result is a bottle with a defined dosage amount at a defined concentration level for a known batch of allergen, all of which is a sterile environment. The allergist or medical professional need only then remove this seal, insert the needle through the rubber stopper and extract the appropriate amount of diluted allergen. This particular bottle 230 is designed to be a single dose. Thus, the actual amount of material disposed within the bottle will be approximately 1 mL. Typically, the bottles are 5 mL bottles. In this situation, that 5 mL bottle can be modified to maintain the same size but only provide for a single 1 mL dose. This will be described hereinbelow.

After the dilution level is determined for the initial desensitization or at any level in the desensitization regimen, the program flows to a function block 1108 wherein the pharmacist selects concentrate antigen and then goes to the dilution process required order to achieve the desired diluted level. The program then proceeds to a function block 1110 where in the pharmacist enters the NDC code for the base concentrate level and the script level. Basically, what the pharmacist does is enter the antigen name and the dosage level provided by script. The program then proceeds to a function block 1112 in order to perform a lookup in the PBM database for the particular antigen that is associated with the script. This lookup does a correlation, as will be described hereinbelow, to the lowest concentrate level having an NDC for that particular antigen. Knowing the dilution level and the procedure, it is possible to determine what amount of the NDC-carrying concentrate level for that particular antigen was utilized and then a reimbursement obtained and four. This is indicated by the function block 1114 and 1116. The program then flows to an initial End block 1118.

Alternatively, there is provided a vial 1404 which is the result of a different selection of cocktails from the D4 level. This, again, would have the re-antigens in the concentrate level D4/D4/D4. This would again pre-provided to the PDM database which would then, based upon the dilutant level for each of the antigens and the procedure utilized to achieve that dilutant level to relate this back to the antigens utilized at the NDC-carrying concentrate level. If, for example, this vial 1404 resulted in 9 mL of material but the physician only required three doses of 1 mL each for two weeks, this would only required 6.0 mL. The pharmacist might only dispense 6 mL out of the 9 mL to the patient or professional. Even though he doses distributed or 6.0 mL, this 6 mL of final product of D4/D4/D4 of Cat/Dog/Pollen antigen has to be related back to the original antigen value.
In an alternate embodiment, there is a vial 1406 provided that has been provided where in it receives diluted antigens from slightly different and vials. In this operation, the three antigens are D5/D6/D6 and this is provided back to the PDM database. Of interest is that all three vials 1402, 1404 and 1406 will each the input to the PDM system with their procedure and the result will be that, for this example specifically, at the reimbursable be the same, as the starting dilutant will be identical. This is procedure specific and script specific, with the cocktail noted as being patient-specific. The antigens/allergens 902, 904, and 906 may also have been part of the kit described with respect to
