Patent Application
20080153122
Fungal nail infections (onychomycoses) are caused when a fungus enters the tip or side of the nail and continues to grow under the nail. Fungal nail infections are very common and more often occur in males. Infections can occur due to aggressive nail clipping or nail injury, which provide access for fungus to enter under the nail.
Onychomycoses caused by dermatophytes are the most difficult to treat and contribute greatly to the spread of infectious fungi. All current treatments, whether topical or systemic, require long-term administration of agents, typically 48 weeks or longer of daily administration of topical agents and around 6 months for systemic agents. Failure to diligently follow treatments, for topical agents in particular, can lead to unsuccessful treatment outcome and relapse of the condition. Further, although systemic administration may be preferable to ensure patient compliance, oral administration of fungus-inhibiting agents such as itraconazole and ketoconazole are undesirable due to the potential for side effects of such drugs. In fact, the currently approved orally administered antifungal medications require periodic liver toxicity monitoring.
Topically applied antifungal compositions offer an alternative to orally administered compositions, such as those described in U.S. Pat. No. 4,957,730 (substituted 1-hydroxy-2-pyridone compounds, including ciclopirox); U.S. Pat. No. 6,017,920 (antifungal compositions for external use being retentive in the stratum corneum); U.S. Pat. No. 6,143,794 (antifungal agents having benzylamine moiety applied with excipient to adhere to the surface of a nail so that the antifungal is delivered through the nail plate); U.S. Pat. No. 6,231,875 (acidified nail lacquers containing antifungal); and U.S. Pat. No. 7,094,422 (antifungal agents applied with a nail penetration enhancers). However, the compositions known in the art typically require a prescription and frequent visits to a doctor for nail maintenance to ensure treatment compliance and absence of relapse.
a illustrates an example group of items that may be included in an onychomycosis treatment kit, according to an example embodiment of the present invention.
b illustrates an example container for an onychomycosis treatment kit, according to an example embodiment of the present invention.
It would be useful to have a composition readily available to consumers for use without a prescription for treatment of onychomycosis. To accompany such compositions, it would be useful to provide a method or system to assist in treatment compliance in order to help ensure a successful treatment outcome.
One example embodiment of the present invention provides an article of manufacture which may be used to reduce medication error and enhance therapeutic compliance with use of topical medications for treatment of onychomycosis. The article of manufacture may include (a) a pharmaceutical composition for topical application comprising at least one antifungal agent; (b) indicia for self diagnosis of onychomycosis; (c) nail growth monitoring device; (d) coordinating instructions for application of said antifungal medication(s) in a therapeutic regimen; and (e) a unifying container.
Another example embodiment of the present invention provides a prepackaged unitary dispenser for organizing, storing, instructing, and dispensing topical medicament regimens and enhancing patient compliance. The unitary dispenser may contain (a) at least one topically applied antifungal medication; (b) a device to measure the effectiveness of using the antifungal medication(s); and (c) instructions for coordination of the antifungal medication(s) and device as a treatment regimen.
Another example embodiment of the present invention further provides a nail growth monitoring device.
Another example embodiment of the present invention further provides a medical therapy compliance management system for the treatment of onychomycosis with a topically applied antifungal agent, the system comprising instructions for self-diagnosis of onychomycosis, instructions for proper nail trimming for fungal nails, devices and procedures for tracking growth of healthy nail, and instructions for procedures to prevent relapse.
Another example embodiment of the present invention further provides a medical therapy management system for managing medical therapy to a patient, the system comprising: an interactive system for obtaining data from the patient, wherein the interactive system contains a compliance controller coupled to the interactive system, the compliance controller being configured to receive data from the interactive system, the compliance controller configured to generate notifications and or reports to the patient based upon the data received.
In certain embodiments, at least a portion of the nail growth monitoring device comprises a material that allows for at least semi-permanent markings to be made. The material that allows for at least semi-permanent markings may be positioned under at least a portion of the second plurality of horizontal lines 103. In additional embodiments, at least a portion of the nail growth monitoring device comprises a transparent or translucent material. In certain embodiments, the transparent or translucent material is positioned under at least a portion of the first plurality of lines 104. The transparent or translucent areas may allow the patient (e.g. the person with the actual nail fungus or a person that is helping to administer or monitor treatment for the person with the nail fungus) to place the nail growth monitoring device over the toenail to aid in tracking treatment progress and healthy nail growth. The treatment tracking area for nail growth may be associated with an area for notation-marking. For example, a single space 100 within the first plurality of horizontal lines 104 may be directly related to a single space 101 within the second plurality of horizontal lines 103. Part of the second plurality of horizontal lines 103 may be made of a material that allows for semi-permanent markings to be made. A patient may then track nail growth and write notes, such as the date, color of the nail, dosage used, topical drug used, etc. Other approaches to distinguishing different associations may be alternately colored spaces, boxed areas, matching numbers or symbols for corresponding measurement points and writing areas, or a combination thereof. Instructions 105 on the use of the nail growth monitoring device may also be displayed on the surface.
A unique code 102 of the patient may also be listed on the nail growth monitoring device. The unique code may be submitted in order to allow the patient to input and track treatment progress and interact with a compliance controller without having to submit contact information. This may be used in circumstances where a user may be too embarrassed to input his or her own contact information. However, in other embodiments, the code may be a blank space to allow a patient to enter a personal contact information which the patient may later use to create a personal treatment page on a website.
The nail growth monitoring device of the invention included as part of the example embodiments is configured to monitor the growth of health nail as a result of treatment. Administration of the antifungal agent according to procedures described in the example embodiments will typically require a period of time, in some instances up to about six months, before the fungus is entirely killed and new, healthy nail can begin to grow. In fungal nail infections, spread of fungus occurs from the tip of the nail towards the cuticle, whereas nail growth occurs in the opposite direction. As the spread of infection is relatively slow (on the order of days and weeks), a subject will be able to determine the extent of fungus growth by a change in color in the nail by a line demarking the boundary between fungal-infected nail and healthy nail. After a period of treatment to kill the fungus, this fungal boundary will cease its progression towards the cuticle and new, healthy nail growth will be seen emanating from cuticle, forcing the fungal boundary towards the nail tip. Typically, the nail growth monitoring device of the included as part of the example embodiments will be used to measure the extent of healthy nail growth, which will increase over time as treatment is continued to completion according to instructions.
The monitoring device may also include a marking area 113 where the user may record the results of measurements taken using the device, e.g., with a marking instrument such as a pen or pencil. The marking area 113 may include a plurality of indicia related to and associated with the measurement indicia 114, which may be disposed in another section of the measurement device, e.g., along the opposite edge from the measurement indicia 114. The marking area 114 may include printing indicating spaces provided for a patient to take notes and monitor treatment progress. e.g., ovals 111 and 115. The individual marking spaces may be distinguished as separate shapes, e.g. ovals, or different colors, or using letters 116 and 117 or other symbols. The lines in the transparent measurement section 114 may be correspondingly associated to the plurality of indicia by the use of corresponding letters or symbols, such as 118 associated with 117, or matching colors or shading, such as 120 associated with 121. The letters in the figure are ordered upwards from the bottom of the measurement indicia, to symbolize the direction of the growth to the user; however, other orderings of letters, symbols, or numbers may be used.
The plurality of indicia 113 may also be printed on a detachable sheet 119 that may be connected to the growth monitoring device by an attachment mechanism, such as Velcro, tape, or a removable adhesive layer. This would enable the growth monitoring device to be reusable, or usable over a longer period of time, or used for different toes of the same patient. A unique code 112 of the patient may also be listed on the nail growth monitoring device. Instructions 115 on the use of the nail growth monitoring device may also be displayed on the surface.
A patient may have multiple toe nails that have fungus or onychomycosis. The second nail growth monitoring device may indicate which toes are treated and the nail growth monitoring devices of

A nail growth monitoring device 311, such as the example in
The medical therapy compliance management system comprises a compliance controller 404 which generates treatment reminders. In certain embodiments the compliance controller 404 may be configured to receive information concerning compliant treatments. In certain preferred embodiments, the compliance controller 404 may be configured to adjust the generation of the reminders based upon compliant treatments recorded. In certain example embodiments, the medical therapy compliance simply sends reminders to ensure that the patient continues the treatment regimen.
In other example embodiments, the medical therapy compliance management system may also have a medical therapy management system, additionally comprising a database 405, wherein the database may store information such as notes made by the patient, treatment results, treatment effects, dosage levels used, pharmaceutical compositions used, patient contact information, and patient physical profile, such as age, race, etc. The database 405 may use this information in order to monitor the patient's progress, interact with the compliance controller 404 to send reminders to the patient, and adjust the treatment plan as needed. The compiled information of all the patients may also be used to improve the dosage and treatment plans and the compliance controller may also utilize the data from the database 405 to generate detailed reports.
In certain embodiments of the medical therapy compliance management system the reminders are sent electronically or through the communication medium 402, for example as electronic voice messages or text messages sent to a phone, blackberry, or other data receiving device. In additional embodiments, the reminders may comprise text messages sent to an e-mail account.
In certain embodiments, the medical therapy compliance management system may also have a sales system 406, which may determine whether a patient may need certain types of pharmaceutical supplements. The patient may place the order from the system, make a recurring order, or the system may automatically send the necessary drugs for treatment to the patient if the patient provided a shipping address.
If the patient had not purchased a pre-packaged therapeutic device, the patient may access the interactive medical therapy compliance management system, and using the data previously entered by the patient, which may have included the toes that have onychomycosis, the degree of injury to the nails, etc., in 502, the patient may receive a diagnosis and treatment from the system.
In 503, if the patient had not received the pre-packaged therapeutic device, after receiving the diagnosis, the patient may receive a recommendation for a pre-packaged therapeutic device that may be best suited for the patient. For example, if the patient has several toes that have onychomycosis the pre-packaged device may contain more of the topical drug than the patient may receive from a pre-packaged therapeutic device that is purchased in a store. The patient may also choose to modify the pre-packaged therapeutic device. For example, the patient may remove certain tools, such as compliance stickers, or nail trimming tools if the patient wants to reduce price. The patient may already have the tools if the patient had bought previous kits, or if the patient wanted to rely on reminders sent from the system rather than using compliance stickers. The tailored pre-packaged therapeutic device may also provide an option of a variety of different types of topical drugs. For example, if the patient is allergic to certain types of creams, alternatives that are available on the system may be provided. The patient may then place an order to purchase the pre-packaged therapeutic device.
In 504, if the patient had not started treatment, the medical therapy compliance management system may track whether the patient has received the shipment and remind the user to start treatment. The patient may adjust how and when to receive reminders. The patient may receive reminders through a text message, e-mail, or voice mail reminder on a data receiving device (e.g. a phone, blackberry, PDA, laptop, etc.). The patient may also choose to send the reminder once a day or several times a day. For example, the patient may choose to receive a voice mail message in the morning at 7 AM when the patient first wakes up, and an e-mail reminder at 11 PM before the patient is going to bed.
In 505, the patient may follow the instructions provided in the pre-packaged therapeutic device or instructions provided from the medical therapy compliance management system, either from the patient logging into the system to receive instructions or provided along with the reminder message. After the patient has applied the treatment, in 506, the patient may update the patient data online and on the nail growth monitoring device. Using the nail growth monitoring device, the patient may use the transparent portion to make notes or indicate treatment effects online. On the system, the date may automatically be recorded, but on the nail growth monitoring system, the patient may have to write the date and results in.
In 507, after inputting the results, if the treatment is not performing as planned, the system may automatically adjust the treatment plan, such as using a higher dose or more frequent treatment, and this may be recommended to the patient. The treatment may be performing on track, and the patient may receive a progress report comparing the expected progress and the patient's progress. If the patient has multiple toes being treated, treatment for one toe may be progressing better than another. Therefore, when reminders are sent, treatment plans may diverge for the different toes. In 508, if a treatment plan is altered or additional medicine is recommended, the patient may receive a recommended order to receive additional drugs or products which the patient may choose to accept or decline.
In 509, if the treatment plan has not ended, the patient would repeat the process of 504 to 508. Otherwise, if the onychomycosis has been eliminated and the treatment is completed, in 510, the patient may stop using the topical drugs.
In the medical therapy compliance management system, in 550 the system may receive registrations from multiple patients or for the same patient but for multiple toes. If a unique code were being used, each profile may be stored as a different foot for the same patient, but the patient may be able to provide a contact information and the unique code numbers in order to consolidate all the reports and treatment under the same patient. In 551, the system would receive patient profile data as input by the patient, and associate data for each toe under the same patient. In 552, the patient may have already self-diagnosed the condition; however, the system may still provide a diagnosis based on the available data provided by the patient. If the patient has not already received a pre-packaged therapeutic device, the system may optionally, in 503, recommend a tailored therapeutic device. The patient may modify the package and the treatment may then be shipped to the patient.
In 554, a compliance controller may determine that the patient is ready to receive a reminder, which may be based on the patient's preferences. The patient may modify reminders, or have the reminders turned off; however, as a default the patient may receive a reminder at a default contact provided by the patient. In 555, the system may receive any updates on the condition of the various toes that are being treated. This information is recorded and in 556 used to either alter the treatment plan or to provide a progress report for the various toes. If the system recommended a new plan, in 557 an order recommendation may also be provided which may include additional supplies or alternative supplies. The system may then send the order if the patient accepts the new treatment plan. If a new plan is not recommended, the patient may still request additional supplies.
In 558, if the system determines that the treatment is complete, in 559 the system may indicate this to the patient and end the process. Otherwise, 554 to 557 may be repeated until the patient's onychomycosis for all the toes has been treated.
