Brief summary

The main aim is to describe how the treatment burden and challenges of participants, relatives, and doctors during regular Factor VIII and Factor IX infusions to treat hemophilia evolve using a virtual-reality (VR) based solution. The study also aims to find out how well the VR based solution is tolerated and how satisfied the participants, relatives, and doctors are with it. The VR-based solution includes a mobile phone app and a 3D mask. Participants will use the VR-based solution while receiving prophylactic Factor VIII and Factor IX infusions for 4 weeks at home. Participants will visit the clinic for the last infusion; at this time data will be collected from participants, relatives, and doctors

Interventions

DEVICEVirtual-reality (VR) Based Solution

VR-based solution comprises a mobile phone application including explanation on the different steps to be followed to perform infusions in satisfactory conditions, notably as regards safety, as well as VAS for pain and anxiety to be completed at each Factor VIII or Factor IX infusion between inclusion and the Week 4 visit. It also comprises a 3D mask (to be used before or during infusions) including simulation of the infusions themselves (before infusion) and a relaxing and distracting content (during and after infusions).

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With a Patients' Global Impression of Change (PGIC) Score Greater Than (>) 3 Among Participants and CaregiversAt Week 4The PGIC is a 7-point Likert scale, a verbal rating scale that asked the respondent to best describe change in symptoms compared to the beginning of study. Participants/caregivers selected from scale range of 1 (very much worsened) to 7 (very much improved). Higher score indicated improved outcome.
Number of Participants With Absolute Adherence to Infusions Measured by 4-Item Morisky Medication Adherence Scale (MMAS-4) ScoresBaseline up to Week 4The Morisky Medication Adherence Scale in the original version (MMAS-4) is a structured self-report measure of medication-taking behaviour. It consisted of 4 items, with binary scoring (yes/no). Participants scored one point for every 'Yes' answer. A score of 0 to 1 indicated low adherence; a score of 2 to 3 indicated medium adherence, and a score of 4 indicated high adherence.
Number of Participants With Changes in Adherence to Infusions Measured by MMAS-4 by ClassesBaseline up to Week 4The Morisky Medication Adherence Scale in the original version (MMAS-4) is a structured self-report measure of medication-taking behaviour. It consisted of 4 items, with binary scoring (yes/no). Participants scored one point for every 'Yes' answer. A score of 0 to 1 indicated low adherence; a score of 2 to 3 indicated medium adherence, and a score of 4 indicated high adherence.
Number of Participants Who Scored 4 (High Adherence) Using MMAS-4 Scale at Week 4At Week 4The Morisky Medication Adherence Scale in the original version (MMAS-4) is a structured self-report measure of medication-taking behavior.

Number of All Participants With Decrease of at Least One Level of State-Trait Anxiety Inventory Severity (STAI-S)

The STAI-S is a psychological assessment tool used to measure the level of anxiety a person is experiencing at a particular moment in time that assesses both State anxiety (STAI-Y1) and Trait anxiety (STAI-Y2). Each type of anxiety has its own scale of 20 different questions each that are scored on a 4-point scale evaluating how respondents feel right now, at this moment (e.g. from 'Almost Never to 'Almost Always'). Total scores for each (Y1 and Y2) range from 20 to 80, with higher scores correlating with greater anxiety. Severity for each STAI-Y1 and STAI-Y2 is defined by the scores on STAI-S: 20-35 (very low) 36-45 (low) 46-55 (moderate) 56-65 (high) 66-80 (very high). Number of participants with decrease of at least one level of State-Trait Anxiety Inventory- Severity (STAI-S) are reported.

Relative Variation of All Participants Anxiety Measured by State-Trait Anxiety Inventory (STAI-Y) Score

The STAI is a psychological inventory consisting of 40 self-report items on a 4-point Likert scale. The STAI measures two types of anxiety - state anxiety (STAI-Y1) and trait anxiety (STAI-Y2). Higher scores were positively correlated with higher levels of anxiety. Each type of anxiety has its own scale of 20 different questions and were rated on a 4-point scale (e.g. from 'Almost Never to 'Almost Always'). Low scores indicated a mild form of anxiety, and high scores indicated a severe form of anxiety. STAI score ranged from 20 to 80 where higher scores indicated greater anxiety and negative value indicated worst anxiety. Relative variation from baseline at visit (%) = 100 \* Absolute change from baseline at visit (in units) / value at baseline (in units).

Time frame: At Week 4

Population: The FAS included all the participants of the IS for whose at least one assessment at the Week 4 visit was available. Here, number analyzed signifies participants who were evaluable at specified timepoints.

Relative Variation of Caregivers and Adult Participants Quality of Life Measured With the European Quality of Life 5 Dimensions 3-Levels (EQ-5D-3L) Health State Index Score

The EQ-5D-3L is a standardized instrument for use as a measure of health outcome and was administered to adult participants to assess the effect of the treatment on the participants' quality of life. Adult participants selected answer for each of the following 3-level dimensions: 1) mobility; 2) self-care; 3) usual activities; 4) pain/discomfort; 5) anxiety/depression used to compute an index score ranging from 0 (worst imaginable health state) to 1 (best imaginable health state). An increase in the EQ-5D-3L index score indicated improvement and negative value indicated worst health. Relative variation from baseline at visit (%) = 100 \* Absolute change from baseline at visit (in units) / value at baseline (in units).

Time frame: At Week 4

Population: The FAS included all the participants of the IS for whose at least one assessment at the Week 4 visit was available. Here, overall number of participants analyzed signifies participants who were evaluable for this outcome measure and number analyzed signifies participants who were evaluable at specified timepoints.

Relative Variation of Participants Depression Measured by Patient Health Questionnaire (Module 9) (PHQ-9) Depression Severity

The PHQ-9 measures self-reports of depressive symptoms within the prior 2 weeks and has been well-validated, shown high test-retest reliability, shown high internal consistency, and shown to be responsive to changes in treatment. Response options were on a 4-point scale (0 = not at all, 3 = nearly every day). The overall PHQ-9 score ranged from 0 to 27 where 0-5 (none) 5-10 (mild) 10-15 (moderate) 15-20 (moderately severe) 20-27 (severe). Higher values represented more severe depression status. Relative variation from baseline at visit (%) = 100 \* Absolute change from baseline at visit (in units) / value at baseline (in units).
