Atorvastatin and Alkali Therapy in Patients With Autosomal Dominant Polycystic Kidney Disease
A Phase 2 study testing Atorvastatin 20 Mg Oral Tablet and Sodium Bicarbonate 600 Mg Oral Tablet in people with Autosomal Dominant Polycystic Kidney Disease and Chronic Kidney Diseases, run by Taipei Medical University Shuang Ho Hospital at 3 sites in Taiwan.
Trial summary
Polycystic Kidney Disease (PKD) is the most common genetic disease leading to End Stage Kidney Disease (ESKD), affecting between 1 in 500-1000 individuals from every ethnic group. The autosomal dominant (ADPKD) form arises from a two-hit downregulation of proteins encoded by either PKD1 or PKD2. Read more about this study

This diagnosis will take place prior to recruitment / inclusion into the study.

About this study
Official title: Atorvastatin and Alkali Therapy in Patients With Autosomal Dominant Polycystic Kidney Disease, A Pilot Trial for Safety and Feasibility
Polycystic Kidney Disease (PKD) is the most common genetic disease leading to End Stage Kidney Disease (ESKD), affecting between 1 in 500-1000 individuals from every ethnic group. The autosomal dominant (ADPKD) form arises from a two-hit downregulation of proteins encoded by either PKD1 or PKD2. Although many potential therapies have been studied to slow progression of ADPKD, none to date have been proven to be both safe and effective in slowing disease progression. Cholesterol-lowering agents called statins have shown promise in the treatment of younger ADPKD patients, reducing inflammation and progression as assessed by kidney growth, but their utility appears to be limited in older populations and those with more advanced chronic kidney disease (CKD). Recent evidence suggests that acidosis, as often seen in patients with worsening CKD and which may enhance CKD progression, limits the effectiveness of statins and enhances their potential toxicity. The investigators thus hypothesize that correction of acidosis along with statin treatment will be a safe and effective therapeutic regimen to slow CKD progression in the adult ADPKD population and improve overall quality of life in these patients. To test this hypothesis, the investigators will conduct a pilot open-label randomized clinical trial in ADPKD patients with estimated GFR >45 min (Stage 1-3a CKD) comparing three treatment groups: control, atorvastatin (20 mg po qd), and atorvastatin plus sodium bicarbonate tablets (upto 1800mg po total daily dose) over one year. At the beginning of the study, the investigators will determine the genotype of the trial participants. During the study period, through study visits along with serial blood draws and urinary measurements, the investigators will evaluate safety and tolerability of these treatment regimens, follow renal function and investigate the role of these treatments on acidosis, inflammatory and metabolic biomarkers in patients enrolled at an outpatient facility. Serial follow-up imaging study will also be done in selected patients. This study will establish the framework for larger clinical trials in ADPKD. Moreover, if the results of this study suggest safety/tolerability or potential benefits of statins and alkali therapy in this ADPKD population, the investigators will seek extramural funding for a larger clinical trial to test this therapeutic strategy in ADPKD.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Atorvastatin 20 Mg Oral Tablet and Sodium Bicarbonate 600 Mg Oral Tablet in people with Autosomal Dominant Polycystic Kidney Disease and Chronic Kidney Diseases, run by Taipei Medical University Shuang Ho Hospital at 3 sites in Taiwan.
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 14 inclusion and 15 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: enrolling by invitation, as of the sponsor's last update on 23 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Taiwan. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Changes in kidney function in patients enrolled in different arms of the study (time frame: 12 months). The study lists 11 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 NCT05870007, 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 23 May 2023.
