Real-world Longitudinal Follow-up Study of a Digital Health Application in Erectile Dysfunction

The goal of this observational study is to assess the long-term effectiveness of a digital health application for treating erectile dysfunction in men aged 18 and older. The main questions it aims to answer are:

* Will participants maintain an improvement of their erectile function, that means maintain an improvement of at least 3 points in the IIEF-5 score at 3 months post-therapy? * How does the application affect overall health status and disease-related quality of life?

Participants will:

* Complete validated questionnaires (IIEF-5, PGI-I, QOL-Med) to track erectile function, overall health status, and quality of life at up to two follow-up points after using the app with a 3-month self-management program combining cardiovascular training, pelvic floor exercises, psychological support, and educational content. * Provide information on demographics, risk factors, and other relevant health characteristics for subgroup analysis.

About this study

The intervention that needs to be completed prior participation in this study involves a digital therapy program delivered via a smartphone or tablet application. This program includes several components aimed at addressing different aspects for the treatment of erectile dysfunction:

  • Pelvic Floor Exercises
  • Cardiovascular Exercises
  • Physiotherapeutic Exercises
  • Mental or sexual therapeutic Exercises
  • Educational Content

Overall, the digital therapy program is designed to provide comprehensive support for men with erectile dysfuntion, addressing both physical and psychological aspects of the condition to improve symptom severity, quality of life, and patient activation.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Men with erectile dysfunction of organic origin (ICD 10 code N48.4) and IIEF-5 score < 21 as determined at therapy start with Kranus EDERA
  • Completion of the 12-week app-based therapy with Kranus EDERA
  • Improvement in the IIEF-5 score of ≥ 3 points after completion of the Kranus EDERA therapy compared to the score at the start of the therapy
  • Age over 18

Exclusion criteria

  • Failure to provide informed consent
  • Started a new therapy with Kranus EDERA between the end of the last therapy cycle and patient survey
  • Started PDE-5 inhibitor treatment during the Kranus EDERA therapy or between the end of the last therapy cycle and patient survey
  • Underwent prostatectomy (removal of the prostate gland), radiation or seeds of the prostate gland during the Kranus EDERA therapy or between the end of the last therapy cycle and patient survey
  • Performed auto-injection therapy (SKAT, MUSE) during the Kranus EDERA therapy or between the end of the last therapy cycle and patient survey
  • Obtained a penile implant during the Kranus EDERA therapy or between the end of the last therapy cycle and patient survey
  • Underwent major surgery in the small pelvis with probable impairment of the neurovascular supply (e.g., rectum resection, urinary bladder removal) during the Kranus EDERA therapy or between the end of the last therapy cycle and patient survey
  • Nervous diseases (e.g., multiple sclerosis (MS), Parkinson's disease, stroke, dementia, psychiatric diseases) acquired during the Kranus EDERA therapy or between the end of the last therapy cycle and patient survey
  • Developed pronounced circulatory disorders (peripheral arterial occlusive disease) during the Kranus EDERA therapy or between the end of the last therapy cycle and patient survey
  • Trauma involving the pelvis/penis/spine during the Kranus EDERA therapy or between the end of the last therapy cycle and patient survey
  • Any other newly developed diseases potentially affecting erectile function (e.g., leading to a longer period of hospitalization) during the Kranus EDERA therapy or between the end of the therapy cycle and patient survey

Treatment and study plan

Primary outcomes

  1. Assessment of the real-world longitudinal effect of the intervention

    Time frame: 6 months after start of the app-based therapy

    The primary endpoint is the rate of patients maintaining an IIEF-5 score improvement of ≥ 3 points compared to baseline (start of app-based therapy) after the app-based therapy

Secondary outcomes

  1. Assessment of the real-world effect of the intervention on overall improvement of patients' health status

    Time frame: 6 months after start of the app-based therapy

    Assessment of overall improvement of patients' health status using the PGI-I questionnaire

  2. Assessment of the real-world effect of the intervention on disease-related quality of life

    Time frame: 6 months after start of the app-based therapy

    Assessment of disease-related quality of life using the QOL-Med questionnaire

Other outcomes

  1. Other outcome measures/variables

    Time frame: 6 months after start of the app-based therapy

    • Demographics and patient characteristics (specified in the study protocol)
    • IIEF-5

    •. PGI-I

    • QOL-MED
    • BMI changes
    • Responders (A priori responder definition of patients with the minimal important difference (MID) of an ≥ 3 points IIEF-5 score improvement to assess the maintenance of a therapeutic effect according to the hypothesis this study aims to investigate)

    Derived variables

    • Changes of IIEF-5 from baseline
    • Changes of IIEF-5 from baseline
    • Changes of IIEF-5 from end of therapy
