ABILIFY MYCITE: A FIRST FDA APPROVAL FOR mHEALTH AND CONNECTED MEDICAL DEVICES

On 13 November 2017, we have probably reached a historical new step in digital health (and mHealth) with this market approval from the FDA for “Abilify MyCite“, the first digital tracking-pill which sends data to your doctor. This connected pill is used to track whether patients sufferring from schizophrenia, bipolar I disorder, and depression have taken their medication, which is used for Personal Health Monitoring (‘PHM‘).

As mentionned by Pharmacytimes:

“the approval of the pill and the sensor together represents a first for the FDA“

even if the sensor itself that is used along with aripiprazole (substance used for patient suffering from schizophrenia) was first cleared for use by the FDA in 2012. As secondary or side effects, the clinical trials revealed adverse events such as nausea, vomiting, constipation, headache, dizziness, uncontrollable limb and body movements (akathisia), anxiety, insomnia, and restlessness. However, the common adverse events associated with the sensor were related to the patch, and were predominantly skin irritation.

TECHNOLOGY AND FUNCTIONALITIES – How it works

On the technology side, the sensor embedded into the Ability MyCite pill syncs with a smartphone and sends an alert to the patient’s smartphone. The doctor receives also a notification through the App when the medication is ingested via a patch that is worn on the surface of the skin of the patient. If the patient shares its data with his practitioner, the latter has the ability to monitor whether the patient has ingested properly. According to the US TV channel PBS, researchers are also trying to manufacture ePills that collect and process other body-related data by monitoring internal heat of the body for several days long.

TECHNICAL ASPECTS OF THE DEVICE

According to LiveScience, the technical aspects are as follows:

“It’s a partial power source, “the patient becomes the battery”. The pill integrates a silicon chip with a logic circuit and contains copper and magnesium.  The chip’s logic circuit makes a small modulated current — a graph of the current levels would look like a sine wave. Since the human body is conductive, the wearable sensor can pick up the changes. The modulated current can encode ones and zeroes, similar to an FM signal. “It works in a similar way as an EKG,” or electrocardiogram. These machines pick up on changes in electrical current in the body to monitor heartbeats. The wearable sensor does the same thing, though the current is smaller.” The pill is designed to work for only about 3 minutes. That’s just enough time for it to send a signal to the wearable sensor that it should wake up and start gathering data. That saves battery power and allows the wearable sensor to work for a week at a time.

The patch and sensor is manufactured by the company Proteus Digital Health and aripiprazole marketed by Otsuka Pharmaceutical.

ETHICS AND LEGAL ISSUES

PATIENT MONITORING AND REDUCING HEALTH COSTS

Personal Health Monitoring (‘PHM ‘) contains at least two major advantages.

MEDICAL COMPLIANCE – being the “consistency and accuracy with which someone follows the regimen prescribed by a physician or other health professional“. In the context of mental disability, the physician must ensure that the patient suffering from a mental disorder takes the prescribed medication on a regular basis. This may be particularly interesting for patients who may find themselves incapable of making a proper judgement (such as elder people). In the USA, a study from the National center for biotechnology information showed that “an estimated 50% of those who respond well to medications are nonadherent to their treatment regime“. Therefore, medical compliance is also a important challenge for patients who are suffering from a mental illness; and

HEALTHCARE COSTS – which could be reduced if more patients would take their pill properly. Consequences are both medical and financial. When a patient do not or, forgets to, take a pill, or do not follow the treatment as prescribed, his/her health may be worsened and this person may require treatment adjustment, more medicine, another hospitalisation or even a further surgery should there be a need to. In particular, this article indicates that the “loss that the taxpayer incurs when patients fail to take their medication, the cost of which is assumed to be at least $100 billion. According to an American report, these numbers could even be between $100 et $300 billion.

TECHNOLOGICAL ADVANCEMENT: YES.  BUT AT WHAT COST AND
TO WHAT EXTENT DOES THIS REMAIN A PROGRESS?

Although such technological advancement (connected pill to track patient’s medical compliance) is remarkable for healthcare costs reduction, not everybody agrees to it, especially within the medical profession. Moreover, it is legitimate to ask to what extent such technology can constitute a practical improvement, not just a scientific progress.

What value does this progress add for patients, the healthcare system and the society in general? What does it improve, is it better than before? If yes, how and what are the bad sides of it? What is the balance between the bad and good sides of this? Will the benefits for the patient override financial benefits?

Some people already rose their voice and expressed reluctance to Personal Health Monitoring (‘PHM’), which scientists have already looked into and published on this complex topic. (see additional notes on that topic at the end of this article).

Altough a few have called this practice “medical Big Brother (or biomedical Big Brother according to the New York Times), PHM raises a number of ethical questions, which can lead to at least 8 key  points and interrogations:

1. Privacy – for personal health monitoring, two types of privacy aspects can emerge, which are personal privacy and data privacy. This also relates to risk of interference in the private life of the patient by collecting and processing health (sensitive or even biometric) patient data. Is such data processing in compliance with explicit consent of the patient, who may not able to make a proper judgement?  This article describes very well some privacy aspects  that personal health monitoring are raising.

2. Visibility or  obstrusiveness – Visibility appears to refer to “the degree to which a PHM device is noticeable by the user and other individuals, both at home and in public“. In accepting the use of tracking devices for dementia patients, cognitively intact older adults identified ease of use, size and weight as important in accepting a tracking technology. One consider the patient differently, being seen as an ill human being. This may create a risk of discrimination by the society and the person might be more vulnerable;

3. (over)Medicalization – the devices have the effect of reminding the user or occupants of a medical condition in a non-medical environment. The home could be turned into a medical environment or “de facto intensive care unit” as well as creating stigmatization linked to the fact that the person feels under surveillance;

4. Social isolation – the patient monitored will reduce or cease going to the hospital or to see the physician for regular check-ups. Therefore, this could increase patient’s loneliness and social isolation with psychological and medical consequences with a lack of motivation and reduction of the mentality;

5. Autonomy – what room remains to the patient with PHM to decide how to take the pill or not? What if the patient wishes to stop taking the pill, for good reasons? Where are we talking about pressure on the patient will?

6. Shame et identity – what consequences could there be on the personality of the patient, who may be perceived by the society as marginal human being, in particular when the treatment is visible?

7. Providing healthcare – with remote care, to what extent does this improve or reduce its effectiveness, especially when the patient does not move him/herself anymore? Is this an efficient manner to treat a patient, shall this remain the exclusive way of doing it or should we combine it with physical appointments?

8. Security and reliability of the technology. This element is obviously central for both privacy and health reasons.

Do these aspects reduce or delete the patient’s responsibility or does it create an over-responsibility? With or without benefits?

How about from an insurance point of view if the patient do not takes the pill while he/she is being monitored with or without worsening of his/her health? Suspension, reduction, cessation of the payment by the insurance or the medical measures? To what extent can the insurance have access to such information or personal health-related data?

A PRIVACY PERSPECTIVE?

As this article pointed out, despite huge costs reductions (around 100 billion) and health benefits of this mHealth technology for the healthcare system and patients, patient’s privacy is an area of concern which is even more related to medtech technologies with Big data and IoT (Internet of Things) in the healthcare sector. Combined with the patch worn by the patient, the sensors that are embedded into the pill may provide far more data about the patient than just taking a pill or not.  The device may be used in a way to gather data from the patient’s body, such as the heart rate, how much the patient sleeps, how fit the patient is, etc.

The major concern is the misuse of such sensitive data, which could be used by corporations or government to collect more personal and biometric information about citizens that they had consented to revealing. Furthermore, since the technology has only recently come into the public domain, very few regulations exist to police it, says this article. Misuse for marketing purposes, is one thing. Data breach, criminal intents, or cyberattack on the device itself are another thing with severe consequences for both patients’ health, privacy and reputations of tech and pharma organizations. Further, another study explains that it appears impossible to obtain informed consent from recipients of PHM because full understanding of the implications of using PHM cannot be gained without actually using the technology. Therefore, using the technology without informed consent, may be considered as illegal processing, which creates a vicious circle. This article suggests that piloting methods such as storytelling and prototyping may present a possible solution to this problem and avoid collecting personal data without the proper legal basis for processing.

________________________________

PRIVACY AND INFORMATION SECURITY 

From an EU and Swiss perspective, health-related data (health or biometric) is considered as a special category of personal data that we call “sensitive data“, where the processing is generally prohibited, unless the controller can demonstrate a legal ground for the processing, such as the patient’s explicit consent (art. 9 §2 (a) GDPR, art. 4 al. 5 and 13 al. 1 of the Swiss DPA), the provision of medical services by a health professional tied by a secrecy obligation (art. 9 §2 (h) and 9 §3 of the GDPR) or private overriding interests (art. 13 al. 2 of the Swiss DPA). As one can read in the press almost everyday now, cyberattacks can happen, and a data breach may lead authorities to impose hefty fines, with 4% of worldwide annual turnover according to article 83 of the GDPR, although fines should remain a last resort in the sanction mechanism applied by the authorities. I wrote a note in this article about the envisaged approach with fines and sanction pursuant to the GDPR.

In addition, the doctor would also have to require the patient’s prior explicit consent before sharing, or allowing any third party to access, any sensitive data . See my previous note on recommendations for outsourcing in the context of medical billing for healthcare professionnals.

There are many other obligations under these regulations, which this article does not intend to cover.

CONCLUSION

This FDA approval sounds like a very good “signal” to pharmaceutical companies developing connected drugs and advanced digital life science technologies, mHealth and medical devices.  This can improve the life of many patients, while saving costs and improving efficiencies in the treatment.

There is no need for scaremongering. However, remaining careful using the device for the purpose of the treatment, informing the patient and gathering explicit consent, processing only the data that is necessary for the purpose of the treatment, working with ethics and respect for the individual, especially if these patients have a reduced of discernment, are some good steps to ensure the individual’s privacy.
