Summary description of the investigational device:
The RITA "Remote Intelligence for Therapeutic Adherence" application was designed, on the
doctor's side, as a support for the management of the onco-hematological patient and, on the
patient's side, as a first aid tool for the management of the most common problems, as well
as an efficient and "non-invasive" means of communication with the doctor. The system also
allows the caregiver and general practitioner to be included in the communication group.
The added value of the app consists in improving the relationship between the patient and the
doctor, creating an effective communication channel, increasing the safety the patient has
when facing his difficult path, reducing the number of visits to the facility and, in
general, making those visits more efficient, thus creating savings both in terms of time and
resources. RITA is also designed to communicate and receive information on the quality of
life and side effects, thus making the medical doctor aware of the progress of treatments in
his patient population.
Often occurs that the mild drug/disease related symptoms that the patient perceive during the
treatment period are underestimated, leading to a more severe symptomatology that could
impair the patient adherence to treatment. Thanks to the app RITA, on the patients side it
will be easier to notify their daily physical condition, while on the physician side it will
be easier to manage and solve the mild symptoms the patient could face during the treatment
period, improving the overall adherence to the treatment.
The mobile app, which can also be used on a conventional desktop or laptop, aims to optimize
the interaction between the onco-hematological patient and the referring physician. The
hospital doctor will have access to the website, in order to manage all the functions through
the appropriate dashboard.
Intended purpose of the investigational device in the proposed clinical investigation:
The application allows, on the patient side, to:
- - record the relevant symptoms, with a simple classification, to be reported to the doctor
at the next visit;
- record Quality of Life (QoL) data at pre-selected timepoints;
- inform the doctor about the necessary drug prescriptions;
- contact the doctor for advice for the same day;
- receive suggestions, through both video and text, specific to the most common problems
that patients may face (the advice can be specific in relation to the type of treatment
carried out).
The consultation is personalized by the attending physician based on the
clinical characteristics of the patient, and the personalization takes place through the
selection of a series of profiles created for the different types of patients (e.g.
fever in patients with mild, moderate or severe impaired immune system, etc.);
- - monitor relevant clinical parameters, such as: temperature, heart rate, blood pressure,
oxygen saturation, respiratory rate, glycemia;
- report information on the quality of life by filling in a specific questionnaire at
defined timepoints;
- monitor the intake of specific drugs;
- manage contacts with the caregiver.
While, on the hospital doctor side, the website allows to:
- - have a quick and complete overview of the problems suffered by the patient in the period
since the last visit, thus making the visit faster and more productive;
- have information related to different and relevant clinical parameters measured and
inserted from the patient, including temperature, heart rate, blood pressure, oxygen
saturation, respiratory rate, glycemia; the collection of this information will allow
the doctor to have patient's information necessary to carry out the appropriate clinical
assessments on response to therapy, stability and/or relapse of the disease.
For
example, the temperature value can be communicated directly to the doctor to anticipate
the prescription of the antibiotic;
- - facilitate the home management of the most common clinical problems that the patient can
face, through videos and texts, customizable by the doctor, which explain how to deal
with the most common symptoms in an initial phase;
- know in advance the drug prescriptions needed by the patient, thus allowing to assign
the prescription activity to the support staff;
- collect in a single "container" all daily communications of patients, which are normally
dispersed in a multiplicity of channels (telephone calls, faxes, e-mails), in order to
be able to manage them conveniently;
- easily communicate with the caregiver;
- monitor patients' QoL prospectively.
Description of the specific medical procedures involved in the use of the investigational
device:
Possible features of the RITA app:
- - possibility of reminder for drugs intake;
- possibility of creating a grading or threshold levels in case of symptoms such as fever
(e.g., temperature at 37.1°C or 39°C); then a response is generated based on the grading
(e.g., "go to the emergency room" or "take a drug'');
- possibility for the doctor to select the advice to send to the patient;
- possibility for the doctor to select the type of pathology and the characteristics of
the patient (e.g., immunodepressed patient);
- possibility of integrating diets and ad hoc menus based on drugs administered;
- possibility of inserting tutorials (e.g., how to send blood counts values);
- possibility of uploading contents: both the doctor and the patient can send texts or
multimedia contents;
- possibility of sending a warning about adherence to therapy both to the doctor and to
the caregiver.
Rationale for benefit-risk ratio.
The major risk for onco-hematologic patients is the progression of their underlying disease
and the consequent reduction in the quality of life, which can be accelerated by a reduced
adherence to the therapy. Risks associated with participation in the clinical investigation
are the same as the risks identified for the general use. No additional risk is identified,
specifically related to the participation in the clinical investigation, as the patient does
not receive a lowered standard of care. Moreover, no special risks are reported due to the
use of applications for adherence to treatment.
Therefore, the potential risks identified in association with the treatment administered with
the App RITA are justified by the anticipated benefits resulting from the implementation of
the standard of care aiming at improving the patients' involvement in their own health
management and intended increase of adherence to treatment.
Primary Objective. The primary objective is the evaluation of patients' compliance to treatment through the use
of the app RITA, thanks to more efficient management of the patients' mild symptoms that
could, if not promptly treated, lead to a more severe condition and sometimes to the
treatment interruption.
Secondary Objectives.
- - Reduction of grade 3-4 treatment-related adverse events.
- - Reduction in the number of visits to the emergency room for complications not requiring
hospitalization: careful monitoring of the patient, both during follow-up visits and
through the use of the RITA app, allows for better control of complications, reducing
the patient's need to access the emergency room.
- - Reduction in the number of visits to the emergency room for severe complications
requiring hospitalization: careful monitoring of the patient, both during follow-up
visits and through the use of the RITA app, allows for better control of complications,
reducing the patient's need to access the emergency room.
- - Reduction in the average number of days in hospital stay: through careful monitoring of
the patient, both during follow-up visits and through the use of the RITA app, it is
possible to reduce the occurrence of severe complications that may require the patient
to be hospitalized.
This objective evaluates the average number of days of
hospitalization of the patient due to the onset of complications.
- - Improvement in the quality of life perceived by the patient: the use of tools in order
to assess the quality of life (for example: questionnaires) allows the medical doctor to
check the patient's perception of health and identify any limitations in daily life
activities.
A constant survey allows to identify timely and more effective solutions
aimed at improving the patient's quality of life.
- - User Experience: the use of digital tools (for example: apps, web systems, etc..
), to
support the doctor-patient clinical health interactions, allows continuous monitoring of
the patient both with respect to any clinical complications and with regard to a
worsening of the quality of life. The indicator monitors the overall degree of patient
satisfaction in relation to the use of the RITA app. In this way, it is possible to
verify the real effectiveness of the app and intercept any elements of attention with
respect to the features present.
Primary Endpoint The primary endpoint is the evaluation of the therapeutic adherence measured
as at least the 80% of the relative dose intensity (defined as the ratio of delivered dose
intensity to the prescribed referenced dose intensity, expressed as a percentage) during the
study period. The effectiveness of the RITA app use will be evaluated by comparing results on
therapeutic adherence with a historical group of cancer patients.
Secondary Endpoint. Secondary endpoints based on the comparisons between groups:
- - Number of visits to the emergency room for complications not requiring hospitalization:
analysis will be performed on the population enrolled in the trial versus an historical
control, evaluating the recorded number of visits to the emergency room for minor
complications not requiring hospitalization.
This information will be obtained by
consulting the management control of the hospital or the emergency room system.
- - Number of visits to the emergency room for severe complications requiring
hospitalization: analysis will be performed on the population enrolled in the trial
versus an historical control, evaluating the recorded number of visits to the emergency
room for severe complications requiring hospitalization.
This information will be
obtained by consulting the management control of the hospital or the emergency room
system.
- - Average number of days in hospital stay: analysis will be performed on the population
enrolled in the trial versus an historical control, dividing the number of days in
hospital stay for hematological patients by the number of hematological patients taken
care of.
This information will be obtained by consulting the management control of the
hospital.
- - Number of AE/minor complications not requiring assistance notified by the patient during
the study period, through the app RITA and directly during the clinical visit, compared
to the historical control group.
- - To measure quantitatively the therapeutic adherence through the mean relative dose
intensity (defined as the ratio of delivered dose intensity to the prescribed referenced
dose intensity, expressed as a percentage) during the study period.
Secondary endpoints on the safety assessment of RITA APP:
- - Occurrence of individual adverse events (%) reported during the follow-up period, during
the user session, and during intervals between one use session and the following.
- - Occurrence of device adverse events (%) during the user session.
Medical Device CLASS IIA. Determination of Sample Size With a total of 112 patients (56 patients in the interventional
arm and 56 in the patient-level historical group), this investigation will have 80% power to
detect a 20% improvement in treatment adherence (i.e., in the intervention group, 90% or more
as compared to 70%) (Passardi et al., 2022), with a one-sided type I error rate of 0.05. We
set a goal of enrolling 124 patients to account for a drop-out rate of 10% (Passardi et al.,
2022), with a consequent enrollment of 62 patients per arm.
Statistical Analyses. In the primary analysis, all the patients observed until the end of the study will be
included.
Patients in the historical group will be matched with patients in the prospective
interventional study according to cancer diagnosis and type of anticancer treatment.
The main characteristics of the patients will be reported using descriptive analyses by
tabulating frequencies and percentages (categorical variables) and mean and median values,
standard deviations (SD), quartiles and extreme values (continuous variables). With reference
to comparison between groups, odds ratios (OR) and 95% confidence intervals (CI) will be
calculated to evaluate the effectiveness of the RITA app, using logistic regression models.
The statistical significance limit will be accepted as 5%, and the results below this value
(P < .05) will be considered statistically significant. Comparisons within group (i.e., in
the interventional study group) will be performed by using the paired t-test or the
corresponding Wilcoxon signed-rank test, a non-parametric test for paired samples, after
checking data were normally distributed (based on the Shapiro-Wilk statistic). Comparisons
between groups (i.e., interventional and historical) for continuous data will be analysed
using a two-sided Student's t-test, after checking data were normally distributed (based on
the Shapiro-Wilk statistic) and a two-sided Wilcoxon's rank-sum test otherwise. For
categorical data comparisons between groups will be performed by using the contingency table
analysis with the Chi-square or Fisher's exact test, when appropriate. Explorative analyses,
with descriptive purpose only, will be performed in the subgroups of potential determinants
of adherence of anticancer treatments, including age, gender, educational status, stage of
disease, comorbidities, poly-pharmacy and complexity of oral anticancer
regimens(weekly/daily). Adverse events occurring during the study follow-up will be
tabulated.
