About this study

Official title: Deciphering the Role of Thyroid Hormones in Autosomal Dominant Polycystic Kidney Disease

Autosomal dominant polycystic kidney disease (ADPKD) is a monogenic, rare and life-threatening disease, characterized by the pathological formation of multiple fluid-filled cysts that arise from renal tubules and alter kidney architecture and function. In most patients, the progressive deterioration of renal function ultimately leads to end-stage kidney disease (ESKD) and the need for dialysis or kidney transplantation.

Save the conventional anti-hypertensive strategies, there are currently two disease-specific treatments for ADPKD (Tolvaptan and Octreotide-LAR). However, these drugs are only available to patients at high risk of progression to ESKD, while a remarkable number of ADPKD patients progress to ESKD despite the treatments.

Cyst formation in ADPKD is determined by mutations in two genes encoding two transmembrane proteins: polycystin1 and polycystin2. The pathogenesis of the disease involves a series of phenotypic alterations, including the de-differentiation of epithelial cells, uncontrolled proliferation and abnormal secretion of fluids in the cysts, metabolic remodeling, all phenomena that lead to the progressive loss of renal structure and function . Therefore, to try to investigate the mechanisms of the disease, the investigators should go in search of pleiotropic molecules capable of simultaneously modulating structure, function and metabolism.

Research done so far suggests that thyroid hormones (TH) may also act as pleiotropic modulators in the patho-biology of ADPKD. TH signals play a crucial role in the regulation of cell de-differentiation and cell cycle reactivation, as well as in the metabolism and evolution of cardiac and renal diseases. Interestingly, changes in TH levels have been detected in approximately 80% of patients with chronic renal failure (CKD), whereas patients with ADPKD show a higher incidence of clinical and subclinical hypothyroidism. Despite these evidences, the ability of TH to modulate anti-cystogenic and renoprotective processes in ADPKD has not yet been studied.

The objective of this study is to determine the levels of THs in the serum of ADPKD patients with normal renal function and mild, moderate or severe renal dysfunction, and to correlate them with renal functional parameters.

Study groupRoleWhat they receive
ADPKD patientsExperimentalThe study will include 90 patients with diagnosis of ADPKD based on renal ultrasonography findings or genetic test. Specifically, five groups of patients will be identified according to KDIGO classification: * 18 subjects with normal or high renal function: eGFR ≥90 ml/min/1.73m2 - CKD G1 stage * 18 subjects with mildly decreased renal function: eGFR 89-60 ml/min/1.73m2 - CKD G2 stage * 18 subjects with mildly to moderately decreased renal function: eGFR 59 to 45 ml/min/1.73m2 - CKD G3a stage * 18 subjects with moderately to severely decreased renal function: eGFR 44 to 30 ml/min/1.73m2 - CKD G3b stage * 18 subjects with severely decreased renal function: eGFR 29 to 15 ml/min/1.73m2 - CKD G4 stage.
Receives: Other: Blood sampling

Questions about this trial

What is this clinical trial studying?

A study testing Blood sampling in people with Autosomal Dominant Polycystic Kidney, run by Mario Negri Institute for Pharmacological Research at 1 site in Italy.

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 9 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 28 Mar 2024. 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 Italy. 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?

Serum levels of total and free triiodothyronine (T3). (time frame: Once during the study.). The study lists 4 primary outcomes in all. 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 NCT05646420, 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 28 Mar 2024.
