Study summary

The objective of the It MATTERS registry is to collect Real-World Data (RWD) to monitor the safe and effective use of commercially available Boston Scientific Corporation (BSC) penile prostheses

Read the detailed description

IT MATTERS is a prospective, multicenter, observational registry that is part of planned, active post market clinical follow-up (PMCF) activity associated with each device.

The study will include adult males who undergo penile prothesis implantation with a market approved BSC device to treat erectile dysfunction.

Study population

Adult males who meet the indications for surgical correction of erectile dysfunction will be enrolled.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. ≥ 18 years of age.
  2. Males who are determined to be suitable candidates and scheduled to undergo surgical implantation of a market approved BSC penile prothesis by their physician.
  3. Willing and able to complete the process.
  4. Willing and able to comply with the follow-up requirements.

Exclusion criteria

Exclusion Criteria:

  1. Males who are deemed by their physician as not suitable candidates for a penile prosthesis.
  2. In the opinion of the investigator, it is not in best interest of the patient or the study for the patient to participate.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Change from baseline to six months in the Erectile Function domain ofthe International Index of Erectile Function (IIEF-EF) questionnaire for Tactra

    The International Index of Erectile Function (IIEF) is a validated, widely used, multidimensional self-report instrument for the evaluation of erectile function. It consists of 15 items that assess sexual function in five domains: erectile function (Q1, 2, 3, 4, 5,15), orgasmic function (Q9,10), sexual desire (Q11,12), intercourse satisfaction (Q 6,7,8) and overall satisfaction (Q 13,14). A score of 0-5 is awarded to each of the 15 questions. The IIEF-15 total score is the sum of the ordinal responses to the 5 domains. The erectile function (EF) domain is the most sensitive domain of the IIEF. IIEF-EF score ranges from 1 to 30 and is derived by scoring 0 (poorest function) to 5 (best function) on each of six questions function (Q1, 2, 3, 4, 5, 15). There are five categories of erectile function based on EF domain score: severe (1-10), moderate (11-16), mild to moderate (17-21), mild (22-25) and no ED (26-30).

    Time frame: Baseline to 6 months

Secondary outcomes

  1. Change in depressive symptoms and overall sexual function at Post-Surgery, 6 months, and 12 months post device implantation compared to baseline, as measured by the PHQ-9 Depression Questionnaire and the IIEF: Total Score.

    The Patient Health Questionnaire (PHQ) is a diagnostic tool for mental health disorders used by health care professionals. The PHQ contains: mood anxiety, alcohol, eating, and somatoform modules. The PHQ-9, is a validated tool specific to depression, scoring each of the 9 DSM-IV criteria. Scored from 0-27, the PHQ-9 is separated into five different diagnoses: minimal depression (0-4), mild depression (5-9), moderate depression (10-14), moderately severe depression (15-19), and severe depression (20-27).

    Time frame: Post-Surgery, 6 months, and 12 months

  2. Change in quality of life at 6 months, and 12 months post device implantation compared to baseline as measured by the WPAI:GH Questionnaire.

    The WPAI:GH (Work Productivity and Activity Impairment Questionnaire: General Health) is a validated tool that asks a series of questions about the effect of subject health problems, both physical and emotional, on their ability to work and perform regular activities. The WPAI:GH outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes, as following 6 questions: 1 = currently employed, 2 = hours missed due to health problems, 3 = hours missed other reasons, 4 = hours actually worked, 5 = degree health affected productivity while working, 6 = degree health affected regular activities. Scores are then multiplied by 100 to be expressed in percentages.

    Time frame: 6 months, and 12 months

  3. Change in erectile function at post-surgery, and 12 months post device implantation compared to baseline, as measured by the International Index of Erectile Function Domain (IIEF).

    The International Index of Erectile Function (IIEF) is a validated, widely used, multidimensional self-report instrument for the evaluation of erectile function. It consists of 15 items that assess sexual function in five domains: erectile function (Q1, 2, 3, 4, 5,15), orgasmic function (Q9,10), sexual desire (Q11,12), intercourse satisfaction (Q 6,7,8) and overall satisfaction (Q 13,14). A score of 0-5 is awarded to each of the 15 questions. The IIEF-15 total score is the sum of the ordinal responses to the 5 domains. The erectile function (EF) domain is the most sensitive domain of the IIEF. IIEF-EF score ranges from 1 to 30 and is derived by scoring 0 (poorest function) to 5 (best function) on each of six questions function (Q1, 2, 3, 4, 5, 15). There are five categories of erectile function based on EF domain score: severe (1-10), moderate (11-16), mild to moderate (17-21), mild (22-25) and no ED (26-30).

    Time frame: Post-Surgery, and 12 months

Other outcomes

  1. Device satisfaction at post-surgery, 6 months, and 12 months a measured by the Likert scale.

    The Likert scale has the options of Very Satisfied, Dissatisfied, Neither Satisfied nor Dissatisfied, Satisfied and Very Satisfied. Responses will be evaluated categorically.

    Time frame: Post-surgery, 6 months, and 12 months

  2. Assess for outcomes and adverse events on AMS Tools at Post Procedure.

    AMS tools will be assess by a physician survey as part of the post-procedure case report form.

    Time frame: Collected only at Post-Procedure
