Development and Evaluation of a New Technological Way of Engaging Patients and Enhancing Understanding of Drug Tolerability in Early Clinical Development: PROACT

Abstract

Introduction

During early clinical testing of a new medication, it is critical to understand and characterise patient tolerability. However, in early clinical studies, it is difficult for patients to contribute directly to the sponsors’ understanding of a new compound. Patient reported opinions about clinical tolerability (PROACT) provides a new, simple and innovative way in which patients can collaborate using an application downloaded to a mobile computer or smartphone.

Methods

PROACT was designed with special consideration given to patient confidentiality, patient engagement and data security. A pilot study was conducted to investigate patient uptake of PROACT and to characterize clinical trial information it captured. Patients recruited to Phase I oncology trials at a UK center were eligible to participate but were required to have a tablet computer or smartphone. Patients used PROACT to upload audio/video messages that became available instantly to their clinical team, who were able to reply to the patient within PROACT. The patient’s message was also analyzed, personally-identifiable information removed and anonymized information then made available to the sponsor in an analytics module for decision-making. In parallel, a patient focus group was engaged to provide feedback on communication needs during early clinical trials and the PROACT concept.

Results

Of the 16 patients informed of PROACT, 8 had a smart device and consented to take part. Use of PROACT varied and all messages volunteered were relevant and informative for drug development. Topics disclosed included tolerability impacts, study design, and drug formulation. Alignment with the clinical study data provided a richer understanding of tolerability and treatment consequences. This information was available to be shared among the clinical team and the sponsor, to improve patient support and experience. Patient forum feedback endorsed the concept and provided further information to enhance the application.

Conclusion

Overall, PROACT achieved proof of concept in this small pilot study and delivered a secure end-to-end system that protected patient privacy and provided preliminary insight into patient experiences beyond the usual clinical trial data set. The use of mobile devices to interact actively with participants in clinical trials may be a new way of engaging and empowering patients. Further validation of this technology in larger patient cohorts is ongoing.

Introduction

Pharmaceutical innovation is based on cutting edge science with the ultimate aim of improving patients’ lives. However, the path from innovation through development is complex and highly regulated [1] with well-defined but proscriptive technical requirements for the conduct of clinical trials [2]. Furthermore, patient outcomes are also dependent on compliance [3], and those who do not engage, and therefore, do not comply are likely to derive lesser benefit. It is no longer acceptable to rely solely on the scientific output of the clinical study when the patient’s experience of the drug and choices made may be of equal importance, both to the sponsor and to the patient.

The principal objective in an open-label Phase I oncology study, is to understand safety, tolerability and other aspects of the drug profile, and thus help define a recommended dose for further investigation [4]. A major component in determining this is deciding which dosing regimen is best tolerated by patients for the duration of study treatment. This is not easy to address with the clinical dataset alone, which is entered by the clinical teams in the clinical trial site, and categorical in the nature of the data collection, particularly recording of adverse events. For example, there may be significant resolution in the severity or distribution of an event which still remains within the same severity category, e.g., mild. As the patients themselves cannot ordinarily share their experiences directly with a clinical study sponsor, it is generally the information in the case report form [5] that is solely relied upon for drug development decisions. In this case, this gives the impression of constancy when in fact, there may have been, to the patient at least, a significant reduction in the treatment burden experienced. Incorporating patient-driven insight, that is shared directly with both the medical teams and study sponsors, into this understanding is likely to provide a step-change in interpretation capability and to result in more informed decisions [6, 7], particularly for those adverse events that are not categorized as being serious.

Laws and regulations governing clinical trials and data privacy are there to protect patients not to stifle innovation and productivity. Yet, industry, in general, has found it a challenge to embrace technology within this clinical trial environment. One of the main concerns among clinical trial researchers about technology is the risk that the integrity of the clinical study gets compromised by introducing technology aimed at giving some level of control back to the patient. PROACT (patient reported opinions about clinical tolerability) is an application that is designed to empower patients participating in early clinical studies by giving them a way to directly contribute to drug development on their terms. Patients are at complete liberty to decide whether they want to participate, what information they volunteer, and when they do so, giving them the unique opportunity to contribute as a partner in drug development. In designing this approach, the PROACT team embraced the principles of relevant laws and regulations as part of the solution, not the problem. They used privacy by design and managed to balance the need to maintain the integrity of the clinical trial process so that the clinical trial itself remained objective, unbiased, and uncompromised in its scientific integrity. PROACT breaks through the traditional pharma concept of a ‘communication gap’ between the patients in studies and the researchers developing the drug.

As the PROACT approach is so radically different to traditionally accepted methodology, and shifts the information flow from the sponsor and/or clinical teams, to the patients who drive and choose content, testing this system for the first time brought with it a high level of uncertainty. Therefore, we developed a pilot system, and conducted a pilot study that was limited in scale so that the utility of PROACT could be explored in the clinical oncology setting, without inadvertently increasing risks in other areas. Furthermore, we conducted in parallel a patient forum meeting to enhance our learning and implementation of the system by gathering information on communication needs within early clinical trials and pulling this into the PROACT approach. It is the learning gathered during the pilot and the correlating patient focus group meeting that is presented in this report.

Methods

PROACT Design and Development

PROACT was a password-protected mobile application developed with ease of use and security in mind. It had a help function that contains a video on how to use the application, and a link to a technical support team for help with password resets and any technical issues. The application allowed patients to record messages (audio/video) and for these to be streamed to a server and made instantly viewable to the patient’s onsite clinical team who were then able to respond appropriately. Patients received a return video/audio message in a chronologically arranged ‘message list’ that they were able to view at will.

After a delay of 32 days, the patient’s message was sent through to a small group of independent analysts. This delay was to ensure that any adverse event information was discussed between the patient and their onsite clinical team and that all relevant updates were entered into the clinical study database for reporting as per the clinical study protocol. The analysts removed personally-identifiable information while capturing the patient message which was then relayed to the sponsor’s study team for further analysis (see Fig. 1).

Information flow using PROACT

Patients and medical team members had the ability to trigger deletion of any of their own videos recorded and uploaded to the PROACT system by pressing the ‘delete’ button within the application. This triggered total deletion of that video and associated information (but not analyzed/anonymized data).

Data Storage and Protection

Rigorous controls were implemented to ensure data protection and patient confidentiality. All connections to the PROACT application were secured via https using a digital certificate. Within the PROACT environment, encrypted data were hosted by the Safe Harbor Certified Provider (Rackspace) in accordance with national and international standards on data protection [8–10]. User access to decrypted data was granted at different levels dependent on role (patient, investigator, administrator, sponsor).

Pilot Study Objectives

The pilot study was conducted using a clinical protocol, which had been developed, written and submitted to an Ethics Committee for approval. The objectives were to investigate the uptake and use of PROACT when made available to patients undergoing treatment for cancer in a clinical trial setting and to characterize the information that patients volunteered. The principal focus in this respect was to understand the technicalities and practicalities of the application. The study was also designed to preliminarily assess the potential benefit of receiving direct feedback from patients for the sponsor, and to explore analysis methods that would convert the information into an interpretable dataset while also protecting patient privacy. The objectives were developed with the long-term aim of PROACT being used in a way that fits with patients’ day-to-day lives.

Study Design, Participants, and Data Collection

Patients aged ≥18 years recruited to Phase I AstraZeneca (the sponsor) oncology studies at the Sarah Cannon Research Institute, London, UK were eligible to participate. Patients were also required to have a “smart” phone or tablet computer that they were willing to use (without reimbursement) for the transmission of audio/video recordings. Provision of informed written consent was also required.

Following enrolment, patients downloaded the PROACT application to their “smart” phone or computer tablet and were instructed on its technical use. Beyond technical advice, patients were provided minimal guidance on use of the system. This allowed the sponsor to gather insight into the nature and level of support that PROACT use may require in the future, albeit from a small sample of patients already comfortable with using mobile devices. Patients’ messages were created, transmitted and handled as described previously.

Data Analysis

Data evaluation focused on identifying contextual key words and topics, using manual text analysis of transcribed data. Patient-identifiable data was removed while capturing the message a patient wanted to convey in an interpretable dataset. To enable this, a hierarchical dictionary and flexible coding database were created to allow for aggregation of data, while linking back to the patient’s own words (see Fig. 2). The database comprised a series of entries, each comprising a coded patient identity, date of communication, data category (e.g., safety, efficacy, convenience), data group (e.g., system affected), topic (e.g., specific treatment burden), the patient quote, status of the communicated event/issue, and response/outcome. Also, a simple color scale was included to visualize the impact of the reported topic upon that patient’s wellbeing or daily activities [green, minimal impact on quality of life (also used to describe if an event had resolved or was improving); amber, moderate impact on quality of life, able to generally continue daily living activities with some limitation (also used to describe an ongoing event); red, significant impact on quality of life (also used to describe a new or worsening event)]. The nature and content of the messages, therefore, drove the development of the dictionary and coding database in an iterative process. These outputs were then assessed to see whether they were able to capture the core elements of the patient contribution in a format that would be useful for contributing to drug programme decisions.

Ethical Approval

The study received Ethical Research Committee approval (with positive comments regarding steps taken to ensure patient confidentiality and data protection) and it was conducted in accordance with applicable regulatory requirements and other relevant guidelines, such as patient data privacy requirements previously described [8–10].

Patient Forum

In parallel with the pilot study, we conducted an interactive meeting with patient and carer representatives of the National Cancer Research Institute’s Consumer Forum (in the UK). Participants in a patient focus group were invited to provide insights into the needs of cancer patients during treatment with a focus on communications in the clinical trial environment. Open forum discussions initially concentrated on three main areas: (1) current clinical practice, (2) patient needs, and (3) carer needs and contributions. The first half of the discussion focused on people’s experiences and opinions before the PROACT concept was unveiled (to mitigate against any bias that proposing PROACT may have introduced). The second half of the session focused on discussion and input into PROACT itself: the concept, approach, use, and guidance. Information gathered was used to assess whether any improvements could be made to the use of PROACT during the pilot study, and as well as aiding development of an enhanced version if further evaluation of the application was deemed appropriate.

Results

Patients

Of the 16 patients informed of the PROACT initiative (12 male, 4 female), 8 patients already possessed and used a computer tablet or smartphone and consented to take part. Participating patients were marginally younger (mean age 61 years; range 45–68 years) than those ineligible to participate through lack of access to mobile technology (mean age 67 years; range 51–80 years).

Usage and Information Shared

The use of PROACT varied between individuals, with some patients using the application many times a week and others rarely or not at all (the latter stated that they did not feel that they had much or anything to share). All messages volunteered by patients were very relevant and informative for drug development. Topics covered included the impact of safety and tolerability, relay of self-monitored results (e.g., blood pressure), feedback on study design, and information relating to the formulation of the medications (see Table 1). Patient feedback on the PROACT approach itself was also positive, highlighting the patient’s role in drug development (e.g., “It is gratifying to know that I have a role in the development of the drug. To believe that this may help others in the future is a real reward too.”).

Patient feedback via PROACT provided an extra level of insight. Alignment with the clinical study data provided a richer understanding of tolerability, the impact on patients and the overall consequences (see Table 2).

Data Analysis

The coded database was visualized in a series of graphs to explore potential signals (Fig. 3). All data points were supported with the patient’s own words and these were readily accessible so that the patient’s intended message could be seen by the clinical team.

This ability to work with both aggregated individual data provided efficient interpretation and alignment of patient contributions. Thus, the study sponsor was able to (1) spot trends, such as the most frequently talked about topics and the temporal emergence of topics, (2) identify the aspects of study treatment and/or study conduct having most impact on patients, and (3) identify management techniques that provide the greatest benefit for patients, including some techniques being developed by patients themselves.

Patient Forum Feedback

A total of five patients participated in open discussions regarding communication in early clinical trials and provided evaluation of the PROACT concept. General feedback on communication within early clinical trials showed that there is a need for greater communication involving patients, carers and health care providers, with a focus on patient experience to build empathy, provide reassurance, ensure transparency and to document more patient-orientated information (see Table 3). In the following session, patients were briefly told of the PROACT concept and were asked to discuss its potential features and usage (see Table 4). The group generally agreed that the concept was advantageous and that having a means to send messages between site visits would provide extra insight into the patient experience. Patients considered that being able to send messages ad hoc and at scheduled times to both be beneficial, and they considered an option to receive messages, particularly relating to study status, a key attribute. However, they considered that uptake and usage would depend on ease of use, while security features should be pitched at an appropriate level so as to not be off putting.

Discussion

This study was intended to provide feedback on the utility of PROACT in a small cohort of patients in early oncology clinical trials. Mobile technology has been previously shown to improve clinical outcomes when an interactive application was used by patients and health care providers outside a clinical trial [11]. However, the PROACT interactive application is the first to our knowledge to have been used to give patients a way to contribute to drug understanding on their own terms within a clinical trial. Indeed, this pilot study demonstrated that PROACT is a valid approach to engage and empower patients in early oncology clinical trials and to gain further insight into their experience beyond that captured in the traditional clinical data set. It facilitated communication between patients, the clinical team, and the sponsor, on specific topics such as, safety, dosage administration, and study design, while also providing added and complementary information on tolerability.

The development of PROACT has required successful navigation through the complex regulatory, ethical, and legal landscape of the pharmaceutical industry and regulatory environments. The outcome was a system and process that ensured patient confidentiality and security of data. PROACT also demonstrated that patient communications could be captured and interpreted in a useful format by implementing a hierarchical dictionary and flexible coding database. Bringing these elements together, this small study showed that there are significant potential benefits for patients, the clinical team, and the sponsor. Patients receive an easy-to-use video communication application and a way of linking to a key ‘anchor’ person at the clinical trial site. The onsite clinical team is able to see and review the patients simply and quickly between visits. As patients’ insight is also aggregated for the overall study population, they also receive a better understanding of drug tolerability, thereby gaining a direct understanding from patients across the whole study and in a non-clinical setting, i.e., at home. This enables better understanding and better patient management of tolerability issues during an ongoing clinical study and builds a ‘patient’ knowledge base, which may be used for subsequent related studies. Also, the sponsor receives broad insight into the impact the drug is having on patients that includes information related to tolerability, formulation, convenience, and study conduct. This enables assessment of the recommended dose on a comprehensive dataset generated from both the clinical report form and direct patient feedback.

Limitations of this pilot study include the small sample size, the iterative process that led to the development of the coded database (no saturation criteria were used for feedback topics), use of an early version of the application, and the low uptake rate due to patients not possessing the appropriate technology. Of note, feedback from patients on the use of the application itself was positive, but in spite of this, it became apparent that patients, in general, were not aware of the value their contribution could make. Patients sometimes did not share insight in the pilot study simply because they did not think that anyone would want to know about it. This is a hurdle that needs to be overcome, so that decisions in clinical management and drug development can be based on a broad and rich understanding of patient experiences and needs. Additional guidance will be developed and made available for both patients and medical teams in future. This will include the points that have been learned from the pilot study, topics of interest, the usefulness and value of the information, and imbedding PROACT within standard clinical study communication channels. Additional insight from the patient forum will be used to develop an enhanced version of the PROACT application that will also be made available for download to laptop/desktop computers. It is intended to provide more information on the use of the application and information relating to the study medication together with comprehensive management guidelines (including practical tips from previous patient experiences when taking the drug). In the wider context, it is intended that PROACT be incorporated as an element in the drug development process, contributing to bioinformatics and providing patients with personalized data feedback.

Conclusions

In summary, PROACT achieved initial proof of concept and delivered a secure end-to-end system that protected patient privacy while providing preliminary patient insight into clinical trial participation. In this respect, it appears to provide a new way of engaging and empowering patients with the potential to change the communication paradigm for an ongoing clinical trial. As previous studies have shown, engaged patients who have the skills, ability, and willingness to help manage their own health have better health outcomes at lower cost to the health system [12]. Further validation of this technology in larger patient cohorts using an enhanced application is ongoing.
