About this study

Patients affected by Autosomal Dominant Polycystic Kidney Disease (ADPKD) need a safe and effective long-term treatment regimen. Unfortunately, there are still no disease-specific treatment for ADPKD approved in the US. A rational step towards identifying such agents is to test therapies that have a proven safety profile with mechanisms of action that can counter the disease progression.

The purpose of this study is to investigate whether drinking increased amounts of water (water loading) might slow down polycystic kidney growth or kidney function decline. Water loading can cause the suppression of a pathway that causes fluid buildup and cyst growth. High water intake has been safely used in the clinical setting, such as in the case of kidney stone therapy. New York State tap water is widely available and safe, making it highly cost-effective as well.

Read the detailed description

The study will involve 11 visits to the study site over 19 months. Participants will need to follow specific dietary and fluid recommendations. There will be physical examinations and medical history assessments at each visit. Testing will include undergoing magnetic resonance imaging (MRI), blood and urine tests. Study participants will be compensated for their time. Detailed study procedures will be reviewed upon contact with the study team.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • High Water IntakeOther

    After 6 months of usual, unchanged diet and fluid intake, participants will be asked to increase the daily fluid intake based on the principal investigator's prescription. The actual amount of extra water prescribed will depend on the results of the participant's 24 hour urine test.

Usual Water IntakeNo interventionFor the first 6 months of the study, the participants will continue their usual water intake.
High Water IntakeExperimentalAfter a 6 month period of usual water intake, a high water intake daily amount will be prescribed for 1 year.
Receives: Other: High Water Intake

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in total kidney volume, as measured from magnetic resonance imaging

    Total kidney volumes will be measured before and after the period of high water intake. Kidney volume growth with high water intake will be compared to baseline kidney volume growth.

    Measured: 18 months

Secondary outcomes (2)
  1. Kidney function change

    Blood creatinine levels will be measured and compared before and after the high water intake period.

    Measured: 18 months

  2. Change in urine and blood markers of response to high water intake

    Blood and urine biomarkers of response to high water intake will be measured before and after the period of high water intake.

    Measured: 18 months.

Questions about this trial

What is this clinical trial studying?

A study testing High Water Intake in people with Autosomal Dominant Polycystic Kidney, run by The Rogosin Institute at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in total kidney volume, as measured from magnetic resonance imaging (time frame: 18 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03102632, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2023.
