Study summary

This study aims to determine if the CloudCath device can detect infections related to peritoneal dialysis (peritonitis) as fast or faster than the current standard methods used by patients and doctors to detect such infections.

Read the detailed description

This study will evaluate the safety and effectiveness of the CloudCath System to detect the onset of peritonitis as compared to standard of care.

Study Participants will connect the CloudCath System to their home peritoneal dialysis unit and the CloudCath System will analyze the effluent dialysis solution for changes associated with peritonitis. The system will alert the participant and healthcare provider if it detects a possible infection so they can be formally diagnosed by their healthcare provider.

Following enrollment, Study Participants will use the CloudCath System for 12 continuous months.

Study results from the ACT study will be compared to the results of the CATCH Study (Protocol number CC-P-001; NCT04515498). In CATCH, the Study Participants used a CloudCath System; however, the notification capabilities (per the CloudCath System algorithm) were deactivated.

Eligibility criteria

Key Inclusion Criteria:

  • currently using peritoneal dialysis
  • provides
  • willing to comply with the requirements of the study
  • has cellular data coverage at home

Key Exclusion Criteria:

  • active or history of cancer requiring chemotherapy within prior 6 months
  • signs or symptoms of an active infection within 14 days prior to enrollment
  • peritonitis diagnosis within 30 days prior to enrollment
  • participating in another device or drug study that may potentially affect study results
  • other medical, social or psychological problems that, in the opinion of the investigator, exclude the study participant from the study
Terms in these criteria, in plain language(2)

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Study arms

  • Experimental
    CloudCath detection

    Active monitoring of dialysate effluent by the CloudCath System.

    Device: CloudCath System

Interventions

  • DeviceCloudCath System

    The CloudCath System enables drainage and measures turbidity, reported as a numeric score, in peritoneal dialysate effluent.

06

What researchers measure

Primary outcomes

  1. Time to peritonitis diagnosis

    The time between detection by the CloudCath System and laboratory confirmation of peritonitis.

    Time frame: 12-months

Secondary outcomes

  1. Agreement in peritonitis detection between the CloudCath System and clinical criteria.

    clinical criteria include: white blood cells (WBC) (\>100 cells per microliter or \>0.1 x10\^9/L), polymorphonuclear cells (PMN) (\>50%), microbiology culture results, gram staining, and peritonitis symptoms

    Time frame: 12-months

  2. Agreement in detection of clinically actionable events between the CloudCath System and laboratory reports and/or diagnosis

    Clinically actionable events defined as an event which requires treatment (i.e., prescribing medications, cleaning an exit site, etc) or intervention (i.e., PD catheter manipulation, removal). Events of interest for this protocol include, but are not limited to, peritonitis, exit site or tunnel infection, and peritoneal dialysis (PD) catheter dysfunction (including PD catheter-related bleeding and PD catheter-related drainage issues).

    Time frame: 12-months

  3. Agreement in detection of clinically relevant events based on CloudCath System, as compared to clinical laboratory results or diagnosis of a clinically relevant event.

    Clinically relevant events are defined as clinically actionable events, events treated preventatively or medically relevant events.

    Time frame: 12-months

  4. Sensitivity and Specificity of the CloudCath System to detect peritonitis as compared to diagnostic laboratory testing

    Analysis of sensitivity and specificity of CloudCath System detection of peritonitis, as compared to diagnostic laboratory testing

    Time frame: 12-months
