Description

Injectable Medication Adherence Tracking SystemCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 63 / 667,426 filed July 3, 2024. and titled ‘Injectable Medication Adherence Tracking System,” the entirety of which is incorporated herein by reference.FIELD OF THE INVENTION

[0002] The invention relates to injection devices, such as autoinjectors for injecting liquid medicines into patients for therapeutic treatments and, more particularly, relates to an adherence tracking system for injection devices.BACKGROUND OF THE INVENTION

[0003] Injection devices for administering liquid medicines are known. One type, known as autoinjectors or injector pens, are medical devices that allow patients or their caregivers to self-administer their medications outside a hospital or physician's office and are often used for the management of chronic diseases. One typical autoinjector consists of a prefilled syringe in a mechanical device that deploys a needle and delivers the liquid medication with a single push of a release button. Autoinjectors may also be disposable, and can include safety mechanisms to shield the needle both before and after injection. Examples of known medications that use auto injectors include Mounjaro®, Ozempic®, EpiPen®, etc. Known autoinjectors can be of single use or multiuse. In multiuse systems, the needle of the injector is replaced after each use and the volume of the dose can be controlled by any known component such as a dial.

[0004] Medication non-compliance is a major problem in health care. Medications in the form of pills, capsules, gel-caps, pellets, tablets, etc., are typically provided to a user in adisposable plastic container with a cap, such as a childproof cap. Injectable medications are prescribed through autoinjectors or injector pens. When physicians prescribe medications, they typically advise the patients of a proper medication administration, such as to take the medication at appropriate times in appropriate quantities, to continue taking the medication for the full prescribed regimen, even if the patient feels better, etc. Unfortunately, many patients exhibit poor compliance in properly following the regimens set out by their physicians.

[0005] A variety of products and techniques for reminding patients to take their medications, as prescribed, are known. Some compliance intervention systems offered by health care providers are designed to remind the patient to take the medication and alert a remote caregiver if the patient does not comply with taking the medication as prescribed. Some of these compliance intervention systems include sensors / reminders in the home, a network connection, and outbound messaging to a caregiver or even back to the patient.

[0006] Compliance for medications administered through autoinjectors is an increasing concern.SUMMARY OF THE INVENTION

[0018] The figures show embodiments of the injectable medication adherence tracking (or injectable adherence tracking) (IAT) system in accordance with preferred embodiments of the invention. The system is easy-to-use for patients, with a minimal learning curve, is usable with many existing single-use or multi-use injectors, and can be used in conjunction with known smart caps for unit-of-use medications and a known smart hub to monitor patient vitals. In one embodiment, the IAT system utilizes LTE cellular data transmission such that a patient smartphone app is not needed. The IAT system can also be Bluetooth® based. The device usable with the system can incorporate a text message-based notification system that can provide reminders for medication compliance. With the IAT system, the adherence data is easy to integrate into pharmacy and electronic health record (EHR) systems. The system is also simple to incorporate into existing enterprise workflow s.

[0019] A main component of the IAT system is a tracking device 10 according to a first embodiment that is attachable to an autoinjector 100. In the embodiment of FIGs. 1A to 1C and 2 A to 2D, tracking device 10 is of a clam shell shape, including two hinged halves, namely, main base 12 and connector or front cover or clip 14. which can snap together to secure a provided autoinjector 100 therebetween. The shape of the front cover / clip 14 is adapted to allow the user to adjust the injector for unlocking, priming, and dosage without the need to remove the injector from the IAT device 10. That is, the unlocking, priming, and dosage adjustment can be effected by opening the front cover / clip 14 so as to expose the pertinent dials / buttons on the autoinjector 100 without dismounting from the main base 12. The location of an injector detection switch 16 is shown isolated in FIG 2B. In one embodiment, the injector detection switch 16 is a mechanical switch that is switched from one position if the autoinjector 100 is not mounted, and to a second position when the autoinjector is mounted, with the body of the autoinjector pushing against switch 16 to causethe change in position of the switch. Alternatively, the switch 16 can be of any preferred design, such as infrared emitters and receivers, a non-contact proximity sensor, etc. An administering button 18 is shown in FIGs. 1C and 2D and can be movably attached to the main base 12. Button 18 is designed to engage with the activation button disposed on the autoinjector 100. In this example, the activation button is disposed on the end of the autoinjector 100 that is mounted on main base 12.

[0020] An alternative embodiment is shown in FIGs. 3A and 3B, in which tracking device 20 includes a main base 22, and a connector 24. Connector 24 can wrap around the circumference of autoinjector 100 to secure it to base 22. Connector 24 can utilize any know n type of securing device such a Velcro®, or snap fittings. The second embodiment with connector 24 can more readily accommodate various sizes of autoinjectors 100.

[0021] Main bases 12, 22 of tracking devices 10, 20 include various components in order to enable the smart features of the IAT system. These components include a central processing unit (CPU) or printed circuit board (PCB) as well as appropriate memory, such as a read only memory (ROM) and / or a random access memory (RAM), to control the device, a communications module, such as 5G cellular module or a Bluetooth® module (or other wired or wireless module) for remote communication, a global positioning system (GPS) module, an accelerometer, various sensors such as temperature and humidity sensors, a pressure sensor, and contact sensors, a battery, such as a rechargeable battery, lighting unit(s) such as light emitting diodes (LEDs), a piezoelectric element / device or speaker for audible alerts, one or more buttons or switches, and a display such as an LCD display. Sensors can also be provided to determine whether the cap of the injector 100 has been removed.

[0022] Figure 5 is a schematic diagram of the foregoing electrical / electronic components of the system. Controller 220 of the device 10 can be in the form of a PCB. which receives from and transmits signals to the several electrical components of the device. Controller 220is provided with any suitable memory 215 that it can use as a workspace and to store and retrieve data and programs. The device 10 is provided with a temperature and / or humidity sensor 402, an accelerometer 404, a pressure sensor 410, and a global positioning system (GPS) unit 406 in communication with controller 220. These sensors can be of any configuration known to those in the art. The temperature and / or humidity sensor 402 can sense ambient temperature and / or humidity conditions of the device 10 and can convert those conditions into an electrical signal to supply to controller 220. The pressure sensor 410 can sense pressure applied to the device 10 and / or the injector 100 and can convert those measurements into an electrical signal to supply to controller 220. The pressure sensor 410 can be in the form of a strain gauge, for example, and can be mounted on base 12.

[0023] Controller 220 can be programmed to control the injection operation depending on current or recent temperature and / or humidity conditions. For example, if the temperature or humidity detected by sensor 402 is above a threshold level stored in memory 215, controller 220 can engage a locking mechanism so as not to allow the activation button disposed on the autoinjector 100 to be depressed even if a user has pressed on button 18. This is because certain medications may not be usable if exposed to extreme temperature and humidity conditions. If the ambient conditions potentially render the medication unusable, this feature can prevent the user from using unsafe or ineffective medication. A message indicating that the unit has been in undesirable temperature or humidity conditions can be also displayed on LCD 205 to notify the user as to why dispensing is not being permitted.

[0024] Accelerometer 404 is incorporated into device 10 and can be used to determine the orientation of the device and its movements. Signals from the accelerometer 404 are fed to the controller 220 for processing. Controller 320 can also process the signals from accelerometer 404 to determine whether the device is moving, its velocity and acceleration, and its orientation. The orientation of the device 10 (and hence the orientation of theinjector) at the time of button push can be used to infer the possible injection site. For example, when the user is in a sitting position and the medication is to be self-injected, the orientation of the device will likely differ depending on whether the injection site is the user’s stomach or thigh. Machine learning and user / caregiver feedback can be utilized to improve determination of the injection site. This information can be used to guide the user on future injections per medical recommendations.

[0025] The pressure sensor 410 also can be used to infer the possible injection site, either alone or in conjunction with the accelerometer. That is, the pressure sensor can provide information used to distinguish the site of injection based on the required pressure. For example, an injection site on the human thigh would need more pressure compared to the stomach / abdomen area due to the differing quantities of subcutaneous fat and muscle for a given patient. Other factors will be force or pressure exerted by dominant versus nondominant hand to potentially indicate the side of the body being injected. This analysis, as well as other analyses performed by the IAT system, can be improved with a generative artificial intelligence application (GenAI application).

[0026] Another use of the accelerometer 404, is in damage monitoring. For example, if the controller determines that the device is moving at gravitational acceleration, it assumes that the injector has been dropped and is falling. A locking device (not shown) can be incorporated into the device and be actuated when the controller senses the device is falling, so as to lock movement of the activation button on the injector. Upon detecting a drop, the system can also be programmed to send a message to the user / caregiver to check for damage before the next use.

[0027] GPS unit 406 can be used to track the location of the device 10. This data can be used to track the habits of the user. The device 10 is also provided with a transceiver 225 and / or a USB port 226 connected to controller 220. This allows communication with thedevice remotely or directly. In this manner, any information stored in memory 215 can be downloaded so as to track injection times and compliance. These connections can also be used to program the controller when needed, such as when upgrading its software

[0028] Some injectors include a window' through which one can observe the level of the liquid medication as well as the position and movement of the plunger of the injector 100. With this in mind, device 10 can be further equipped with one or more sensors 28, such as an optical infrared (IR) sensor that includes an emitter-receiver pair to detect presence or breakage of the IR beam as show n in FIG. 2A. If unobstructed, the IR beam emitted from the emitter is received by the receiver. The receiver sends a signal to controller 220 when that signal is received. With the beam being directed through the w indow, sensor 28 can be used to detect the liquid medication level or the plunger position. Controller 220 is programmed to determine the liquid level and or plunger position based on the beam reception or break. The resulting analysis by the controller can be used to determine whether the injector has been actuated and even how much liquid has been injected. This is particularly useful in multiuse systems in which not all of the liquid medication is used in a single dose and the remaining volume can be monitored.

[0029] Other features of the device can be included. For example, some users may lack the strength to press the (and hold down) the actuator button of the injector 100 to dispense / administer the medication. The device can be equipped with a mechanism that engages the actuator button of the injector 100 and presses and holds that button for the necessary duration, so the patient does not have to hold down the button as needed for the autoinjector to administer the required dosage. This mechanism can be triggered by the administering button 18 of the device 10, but relies on the mechanical advantage of the mechanism using springs and / or other components to apply the necessary force to the actuator button of the injector 100. Alternatively, any type of drive device, such as a steppingmotor, can be used to depress the actuator button of the injector 100 once the administering button 18 of the device 10 id depressed. This will make the injector easy to use for those who may have an issue pressing and holding down the injector.

[0030] In an alternate embodiment, the device 30 can be formed as a unitary component attachable to the actuation end of the injector or pen 100 as show n in FIG. 6. The device can detect the actuation of or actuate the injector or pen button or can sense the push of the pen or injector during the injection process. The device can be designed to fit over the actuator button of the injector or pen 100 and includes a trigger or button 32. Triggering the trigger 32 of the device will trigger the actuator button of the injector, by mechanical coupling or otherwise The device can also include sensors which can detect the plunger position. Such can be detected optically when the injector or pen housing has a window or using electric or magnetic (capacitive or electromagnetic) field changes to detect the movement of the plunger of the injector or pen 100. For multi dose injectors rotating the device will adjust the dose selector of the injector, so the dose quantity can be monitored. This version of the device would include similar sensing and control components as the previous embodiments so as to be able to perform similar functions as in the other embodiments.

[0031] As another modification of the unitary device, such can be designed to replace the cap of the injector 100. A switch or other detector can detect that the injector has been removed and sensors, such as the optical IR sensor 28 described above, can be provided to determine the change in levels of the medication before and after administration, allowing the system to determine if the correct dose was administered.

[0032] In one version, the IAT tracking device 10, 20, 30 is provided with three buttons in order to detect injection and device removal. The device can monitor battery state, signal level, location (for example, within about 1 mile accuracy), and firmware events. The device connects wirelessly to a network after each injection. If there is no injection, the device canconnect periodically to report status in a configurable manner. During each connection, the device can check for configuration updates and new firmware. The device can communicate directly with a backend, and the communication is secured via transport layer security7(TLS). In case the device cannot connect to the network, it can store the events to be sent when the network is available. Periodic retries can be programmed.

[0033] The main base unit 12, 22 contains the CPU or PCB and is connected to the injector detection switch 16 and to the administering button 18. The CPU consists of a processing unit and transmission unit. Each event is recorded and transmitted to the data cloud over a wireless connection (e.g., cellular, Bluetooth® or Long Range (LoRa)), or even a wired connection. When the injectable device 100 is inserted into the IAT device 10, 20, 30, the CPU registers the presence of the device. The administering of the medication is recorded when the cap removal is detected and the button 18 is pushed. As noted above, the button 18 is mechanically connected to the actuation button on the injectable device 100, such as through abutment or any suitable connection.

[0034] The IAT tracking device 10, 20 is capable of detecting 1) if the injectable device is in place (loaded / attached to the tracking device) using detection switch 16, which can be a contact sensor, 2) if the administration process has been initiated (e.g., by means of a button push of administering button 18), 3) the datetime stamp and approximate location of the device using the CPU and GPS module, 4) if the administration process conforms with the recommended process (e.g., if the administering button 18 was pressed down for ‘x’ seconds, 5) the orientation of the injectable at the time of button push and / or the pressure applied to the injector to infer the possible injection site (using the accelerometer and / or the pressure sensor), 6) if the dose has been adjusted (e.g., by rotation of a dosage dial on the injectable 100). 7) when the unit has been primed, 8) if the injectable device 100 has been unlocked for dispensing / locked for storage, 9) if the injectable device 100 has been uncapped / capped. 10)if a used injectable device 100 was removed from the IAT tracking device and replaced with anew / fresh device, 11) if the injector 10, 20 is stored within the recommended temperature range, and 12) if a needle was removed / replaced on a multiuse injectable device 100. As to inferring the injection site, the CPU can monitor the orientation of the injectable at the time the injection button is actuated and throughout the injection process using the accelerometer. Upon analyzing the acquired information and comparing with stored data and patient injection history, a probable injection site, such as the patient’s stomach or thigh, can be determined and recorded. Other sensors, such as the pressure sensor, can provide further data to improve accuracy of the inference. This analysis, as well as other analyses performed by the IAT system, can be improved with a generative artificial intelligence application (GenAI application).

[0035] The IAT device 10, 20 in conjunction with the data cloud can notify users with alerts from the IAT device directly or via text message reminders (or via automated voice calls or app based notifications). Alerts and notifications are sent for conditions, such as upcoming medication scheduled doses, missed dose alerts, care manager / provider alerts for missed doses, low adherence alerts, and abuse or overutilization alerts.

[0036] The device 10 is provided with one or more interactive components for communication with the user / caregiver. For example, the CPU can control a speaker 206 to emit various sounds or voice messages and an LED display 204 to emit light of various colors and durations according to particular events or changes in status. The following are examples of lighting scenarios, but are in no way intended to be limiting. The device flashes green when the patient or caregiver removes the cap from the injector 100. The device flashes blue when the patient or caregiver removes the cap from the injector 100 for a second time within two hours of the previous removal, indicating potential medication errors or overdose. When a battery 250 is low, the light flashes red. The device flashes green consistently after thepatient or caregiver removes the cap from the injector and it is ready for use. In this status, the device is waiting for user to inj ect the syringe and push the button. The device emits the green light while the button on the injector is pressed and the cap is removed. This indicates the medication is being administered. After the medication has been administered for the prescribed length of time, the device starts to flash orange until the button is released.

[0037] A basic patient workflow of the IAT system is shown in FIG. 4. In the first step SI, patient onboarding is handled via SMS messaging through the patient’s or caregiver’s smartphone. This can include welcome messages, training videos, etc. After onboarding, the patient and / or caregiver will receive an SMS medication reminder as per medication schedule as in step S2. Then, the caregiver or patient administers the medication and the IAT device 10, 20 monitors the process in step S3. The system can be configured to coach the user through the process. Data is automatically transferred from the IAT device to a system portal for review in step S4. In step S5, the patient or caregiver will be alerted for refill management after each single use application, or after the prescribed number of doses in multi-use applications. When the caregiver or patient is issued a prescription refill in step S6, the depleted injector 100 is removed and a new injector is placed into the IAT device 10, 20. In step S7, usage and monitoring continues as before. Any additional device support can be handled via SMS or other forms of interaction with patients in step S8.

[0038] As noted previously, the IAT system of the present invention can be implemented through LTE and / or Bluetooth® systems, but the invention is not limited to these communication systems. In the LTE system, the IAT system uses cellular network coverage, can use a rechargeable Li-ion battery, and includes a USB port 226 for charging as well as to read the IAT device ID and perform configuration. Firmware upgrades can be performed via the cellular network or USB. In this version, the system can track the replacement of the injector pen 100. track the push of the button 18 to detect the administration of medication,and detect the removal of the injector pen cap. The system can further document if the patient administered the medication properly, identify changes to the injection area, ensure the injector is stored as recommended, and record administered dosages.

[0039] In the Bluetooth® system, the IAT sy stem uses a central device, such as the RxCap DataHub®. The device of this system can be of a smaller form and use a disposable coin cell battery. Near-field communication (NFC) can be used to read in bulk and wakeup the device to allow configuration without opening the box. Firmware upgrades can be performed via Bluetooth® by using a smartphone or the DataHub®. This version can perform all of the functions of the LTE version. It also enables coaching of the patient and prompting the patient through the preparation and administration process.

[0040] Although this invention has been described with respect to certain specific exemplary embodiments, many additional modifications and variations will be apparent to those skilled in the art in light of this disclosure. It is, therefore, to be understood that this invention may be practiced otherwise than as specifically described. Thus, the exemplary embodiments of the invention should be considered in all respects to be illustrative and not restrictive, and the scope of the invention to be determined by any claims supportable by this application and the equivalents thereof, rather than by the foregoing description.
